    The invention relates to vehicles, and specifically to devices for cleaning windshields of vehicles.
    Closest to the invention, the technical solution is a car wiper, driven by a reversing engine, containing a crank, the finger of which is connected to a connecting rod connected to the brush, means for setting the amplitude of the reciprocating movement of the connecting rod in one direction of rotation of the crank of a larger amplitude · when opposite to the right 5 to rotation [1].
    In the known construction, the finger moves relative to the crank in the corresponding slot, and when turning on and off the electric motor * of the wiper drive, the finger hits the edge of the slot, which. leads to wear, interacting 25 between these elements and to reduce the operational reliability of the wiper as a whole.
    The purpose of the invention is to increase durability and simplify the design.
    The goal is achieved in that the finger is rigidly attached to the crank, and the specified tool includes an eccentric mounted on the finger with the possibility of rotation about the axis of the latter and having a protrusion, the axis of symmetry of which is parallel to the axis of the finger with the possibility of relative displacement of these axes in the radial direction when changes in the direction of rotation of the crank, with the stops fixed to the eccentric, the crank has stops for their alternate interaction with the mentioned stops, and the connecting rod is located in constant contact with the cam.
    A spring-loaded lock is mounted on the eccentric, mounted with the possibility of joint rotation with the last one and connected with the connecting rod.
    A notch is made in the eccentric, and the crank has a protrusion mounted in. the recess, while both stops are formed by the edges of the specified protrusion, and both stops - the opposite edges of the recess.
    In FIG. 1 shows the drive mechanism: yes of a vehicle wiper, axial split of FIG. 2 mechanism in two extreme positions with the forward direction of rotation of its crank, top view; in FIG. 3 mechanism, working in the opposite direction, top view 1 ; in FIG. 4 - 5 the amplitude of movement of the brush, driven by the specified mechanism of the wiper with forward and reverse directions of rotation of the crank; in FIG. 5 is a circuit diagram 10 illustrating the power supply of a reversible electric motor used to actuate said wiper mechanism.
    The vehicle’s wiper drive mechanism 15 comprises nylon gears 1 mounted on a short roller 2 and driven by a reversible electric motor (not shown) through a worm gear 20 (not shown).
    Wheel 1 and roller 2 are installed in the housing, to which the motor housing is attached.
    Attached to the upper part of the wheel 1 is a metal plate 3 bearing a crank pin 4, which is directed upward from the wheel 1, and whose longitudinal axis runs parallel to the longitudinal axis of the roller 2 at some distance from it. An eccentric 5 is mounted on the crank pin 4, which rests on the support flange 6, from which the pin 4 leaves, held in place by a spring latch 7, which is included in the ring groove 8, made in the upper part of the pin 4, and under the spring latch 7, a washer 9 is provided to facilitate the rotation of the eccentric 5 relative to the finger 4 of the curved-40 spike.
    to
    The eccentric 5 has a through hole 10 for the crank pin 4. The eccentric 5 also has a lower flange 11 extending outward 45, a round thickening 12 and a protrusion 13 having a pair of flats 14 (Figs. 2 and 3).
    The outer surface of the bulge 12 surrounds the finger 4 and is located on a circle whose axis runs parallel to JU parallel to the axis of the finger 4 at some distance from it. On the bottom side of the flange 11 is formed an arcuate recess 15 extending almost 180 ° at the lower side of the flange 11. The anti 5th bying faces recesses 15 form respective first and second stops 16 and 17.
    The wiper also contains a connecting rod 18 having at one end a through circular hole 19. The eccentric bulge 12 enters the hole 19, so that the axis of the hole 19 is aligned with the axis of the outer surface of the bulge 12, and therefore / 65 runs parallel to the axis of the crank pin 4 on some distance from it. The opposite end of the connecting rod 18 (not shown), as in conventional vehicle wiper drives, carries a hinge axis that enters the slider moving in a straight line and to which one end of the toothed belt is attached .. The toothed belt passes to the pair of gears to which it is attached accordingly, a pair of wiper arms with brushes mounted on them, the swing angle of which depends on the length of the reciprocating movement of the slider.
    The connecting rod 18 is held. In connection with the bulge 12 by means of a cup-shaped clamp 20 pressed against the connecting rod 18 by means of a spring 21 held in place by a spring latch · Icoy 22 and a washer 23 mounted on the protrusion 13 of the cam, the clamp 20 is made with a through hole corresponding to the outer the surface of the protrusion 13, so that the latch 20 is forced. make an angular movement with the eccentric 5, but can move relative to it in the axial direction. The connecting rod 18 is pressed by means of a spring 21 and a latch 20 to the upper surface of the flange 11 (Fig. 1) .j
    On the 'plate 3, an upwardly arched protrusion 24 is protruded using an incomplete shift operation, the opposite edges of which form the first and second stops 25 and 26. The protrusion 24 enters a recess 15 made in the eccentric 5 under the flange 41.
    When the wheel 1 rotates in the direction of the arrow F (FIG. 2), i.e. in the forward direction, the eccentric 5 rotates relative to the crank pin 4 and the plate 3, until the first stop 16 comes into contact with the first stop 25. After this, with the further rotation of the gear 1, the angular movement of the eccentric 5 relative to the crank pin 4 stops, so that both the eccentric and the finger move together. along a circular path around the axis of rotation, wheels 1. The radius of the circular path, i.e. the effective radius of the crank (T ^, Fig. 2) is the distance between the axis of rotation of the wheel 1 and the axis of the thickening 12, i.e. axis relative to the rotation between the eccentric and the connecting rod 18. The first stop 25 and the first stop 16 are so located relative to the bulge 12 that when the wheel 1 rotates, the axis of the bulge 12 moves along a circular path that is radially inside from the circular path along which the axis
    Finger 4 crank. The length of the reciprocal, translational movement of the slider and, therefore, the toothed belt is equal to 2 T ^, while the brushes swing along the swing arc A (Fig. 4, brush 27) Thus, the brush 27 moves along the swing axis a during normal operation , i.e. when color 1 rotates forward F.
    As shown in FIG. 5, a limit switch 29 is connected to the reversible motor 28. A hand-operated switch 30 having four positions I-IV is also included in the circuit. The switch 30 is selected of the type in which the connections made by the switch 30 at each of its four positions are displayed on the indicator. ' At position I, the motor brushes 31 and 32 are connected to the positive and negative sides 12 V of the DC source, respectively, to drive the motor 28, which rotates the wheel 1 in the forward direction F with greater speed. At position II, the brushes 33 and 32 of the motor 28 are connected to the positive and negative sides of the power source to drive the motor 28, which drives the wheel 1 in the forward direction F at low speed.
    When you want to stop the wiper blade 27, select position III. In this position, the motor brush 32 is connected to the positive 'side of the power source, and the brush 33 to the negative side of the power source through a unit 34 containing a time delay controller ·, and a relay and terminal switch 29.
    In this case, the relay of block 34 is in the position shown in FIG. 5 in a solid line, and the limit switch 29 is in the position shown in FIG. 5 with a dashed line. As a result, the direction of the current passing through the motor 28 is reversed and the direction of rotation of the motor is reversed. After changing the direction of rotation of the reversing motor to the reverse wheel 1, it moves in the opposite direction, as shown by arrow R in FIG. 3. When the wheel 1 moves in the opposite direction, the eccentric 5 freely rotates relative to the crank pin 4 until the second stop 17 comes into contact with the second stop 26. When this happens, the eccentric 5 will be limited from turning relative to the crank pin 4, in resulting in the eccentric and the finger moving together in a circular path around the axis of rotation of the wheel 1. '
    Due to the difference in the diameters of the bearing surfaces of the pin 4 and the eccentric 5 and the bearing surfaces of the connecting rod 18 and the eccentric 5, the difference in the friction resistance between the two pairs of bearing surfaces contributes to the relative angular displacement between the eccentric 5 and the pin 4. This difference in the friction resistance is increased by using a cup-shaped retainer 20 and springs 21 pressing the connecting rod 18 to the flange 11 of the cam 5. As a result of changing the relative positions of the stop 26, the stop 17 and the bulge 12, the axis of the bulge 12 moves to position that is outside the axis of the crank pin 4. relative to the axis of rotation of the wheel 1, so that the radius of the crank increases and becomes T ^, as shown in FIG. 3.
    This gives a general increase in the angle of brushing 27 (Fig. 4, arc b). The limit switch 29 is located on the path of the slide, which drives it when it reaches a position corresponding to the lower limit of movement of the wiper blades when they swing along the arc b. In this case, the limit switch 29 moves to the position shown in FIG. a solid line connecting both motor brushes 32 and 33 to the positive side of the power source. This causes dynamic braking of the engine 28, as a result of which the wiper drive mechanism quickly stops, and the wiper blades fit into the initial park position P (Fig. 4). Depending on the moment the driver 30 activates the switch relative to the angular position of the wheel 1, the wiper blades may or may not move to the upper limit of travel before going down to park position P. In the event that the wiper blades 27 must thus move, they move to the limit defined by the arc b, and therefore clean further; than they usually clean during the reciprocating movement along the arc This prevents the formation of an undesirable strip, which would be the case if the brushes 27 were moved to the park position simply by moving the arc a down.
    When the switch 30 is turned to the IV position, the motor brush 32 is connected to the positive side of the power supply, and the relay of the block 34 containing the time delay controller and the relay is energized and moves to the position shown in FIG. 5 with a dashed line.
    Ί
    In this case, the brush of the motor 33 is connected to the negative side of the power source, and the engine starts to work in the opposite direction, so that either jog cleaning (cleaning the windshield with one brush stroke) can be performed when the switch 30 is turned to position IV for some period, or time-delayed cleaning, in which the windshield is cleaned with single movements of the wiper blades with a predetermined time interval set by the time delay controller in block 34. The windshield wiper l in this mode is activated for a moment, and perform complete cleaning of the entire arc b at each movement.
    In the described embodiment, the arc b described by the wiper blades 27 during the course toward the park position is <10 ° greater than the arc a at each end of the course.
    The described device is simply constructive and relatively silent in operation. The frictional effect of the latch 20 on 1 connecting rod 18 ensures that when the direction of rotation of the engine is reversed relative movement between the eccentric 5 and the crank pin 4 from the first rotation position to the second will occur without delay.

    The invention relates to a transport technique, and specifically to devices for cleaning windscreen glasses of transport vehicles. The closest technical solution to the invention is a car wiper having a drive from a reversing engine, comprising a crank, a finger of which is connected to a connecting rod connected to a brush, means for setting the amplitude of the reciprocating movement of the connecting rod in the single direction of rotation of a larger amplitude at the opposite direction of rotation 1. In a known construction, the finger moves relative to the crank in the corresponding slot, and when the electric motor is turned on and off ha wiper drive bodies finger hits against the edges of the slit that. leads to wear and tear, interacting. between these elements and to reduce the operational reliability of the wiper in general. The purpose of the invention is to increase durability and simplify the design. The goal is achieved by the paleC. rigidly attached to the crank, and ykazannaya means includes an eccentric mounted on the finger can be rotated relative to the axis of the latter and having a protrusion whose axis of symmetry is parallel to the axis of the finger with the possibility of relative displacement of these axes in the radial direction with changes in the direction of rotation of the crank, and the eccentric stops are fixed, the crank has stops for their alternate interaction with the said stops, and the connecting rod is in constant contact with the eccentric rykom. On the eccentric, a truncated retainer is installed, mounted with the possibility of joint rotation with the latter and connected with the connecting rod. In the eccentric, a recess is made, and the crank has a protrusion installed in the recess, wherein both limiters are formed by the edges of said protrusion, and both stops are opposite edges of the recess. FIG. 1 shows a vehicle wiper drive mechanism, axial section; in fig. 2 a mechanism in two extreme positions with a forward direction of rotation of its crank, top view; in fig. 3 mechanism working in the opposite direction, from above; in fig. 4 shows the amplitude of the movement of the brush actuated by the indicated wiper mechanism in the forward and reverse directions of the crank rotation in FIG. 5 is a schematic electrical circuit for supplying a reversible electric motor used to drive said glass cleaner mechanism. The vehicle windshield wiper drive mechanism contains nylons. The gear 1 is mounted on a short roller 2 and is driven into rotation by a reversible electric motor (not shown) through a worm gear (not shown). The wheel 1 and the roller 2 are installed in the housing / to which the engine case is attached. A plate 3 is attached to the upper part of the wheel 1 on metal 1, bearing on itself the finger 4 of the crank, which is directed upwards from the wheel 1, and whose longitudinal axis runs parallel to the longitudinal axis of the roller 2 on which is a distance from it. An eccentric 5 is mounted on the crank pin 4 resting on the support flange 6, from which the pin 4 departs, held in place by a spring latch 7 entering the annular groove 8 formed in the upper part of the finger 4, and provided under the spring latch 7 Ball 9 to facilitate the rotation of the eccentric 5 relative to the crank pin 4. The eccentric 5 has a through hole 10 for the finger 4 of the crank. The eccentric 5 also has a lower outwardly extending flange 11, a thickening 12 9 of a round shape and a protrusion 13 having a pair of bald spots 14 (Fig. 2 and 3). The outer surface of the bulge 1 surrounds the finger 4 and is located on a circle, the axis of which passes parallel to the axis of the finger 4 at some distance from it. On the lower side of the flange 11, an arcuate opening 15 is made, passing almost to the lower side of the flange 11. Against the positive edges of the recess 15, the first and second stops 16 and 17 form a responsible manner. The wiper also contains a connecting rod 18 that has a through circular end at one end hole 19. In from version 19 enters a thickening of 12 ex. centric, so that the axis of the hole 19 is coaxial with the axis of the outer surface of the thickening 12, and therefore; runs parallel to the axis of the finger 4 of the crank at some distance from it. The opposite end of the connecting rod 18 (not shown), as in conventional vehicle windscreen drives, bears the hinge axis entering the slide moving in a straight line and to which one end of the toothed belt is attached. Gear toe goes to a pair of gearboxes to which are attached respectively a pair of wiper arms with brushes mounted on them, the swing angle of which depends on the length of the reciprocating movement of the slide. The rod 18 is held in connection with the bulge 12 by means of a cup-shaped clamp 20, pressed against the rod 18 by means of a spring 21 held in place by a spring latch 22 and a washer 23 mounted on the eccentric protrusion 13, the clamp 20 is provided with a through hole corresponding to the outer surface of the protrusion 13 so that the latch 20 is forced to make an angular movement together with the eccentric 5, but can move relative to it in the axial direction. The rod 18 is pressed through the spring 21 and the latch 20 to the upper surface of the flange 11 (Fig. 1). I On the plate 3 is performed using the operation of incomplete shear protruding upward arcuate protrusion 24, the opposite edges of which form the first and second limiters 25 And 26. The ledge 24 enters the recess 15, made in the eccentric 5 under the flange 41. When: wheel 1 rotates in the direction of arrow F (Fig. 2), i.e. in the forward direction, the eccentric 5 rotates relative to the crank pin 4 and plate 3, until the first stop 15 comes into contact with the first limiter 25. Then, with further rotation of the gear 1, the angular movement of the eccentric 5 relative to the crank pin 4, so that both the eccentric and the finger move together. along a circular trajectory around the axis of rotation, wheel 1. The radius of the circular trajectory, i.e. The effective radius of the crank (T, Fig. 2) is the distance between the axis of rotation of the wheel 1 and the axis of thickening 12, i.e. axis relative to the rotation between the eccentric and the connecting rod 18. The first stop 25 and the first stop 16 are so located relative to the thickening 12 that when the wheel 1 rotates, the thickening axis 12 moves along a circular path that is radially inside from the circular path along which the axis of the crank pin 4 moves . The reciprocating movement of the slide and, consequently, the toothed belt is 2 T, while the brushes swing along the swing arc A (Fig. 4, brush 2). Thus, the brush 27 moves along the arc a swing during normal operation, i.e. when wheel 1 rotates c in the forward direction F. As shown in Fig. 5, limit switch 29 is connected to the reversing motor 28. A hand-operated switch 30 with four positions I-IV is also inserted in the circuit. of the type in which the connections made by the switch 30 m at each of its four positions are displayed on the indicator.At position I, the slits 31 and 32 of the engine are connected respectively with the positive and negative sides of a 12 V DC power source to excite the engine 28, which causes the wheel 1 to rotate. in the forward direction F at a higher speed. At position II, the brushes 33 and 32 of the engine .28 are connected to the positive and negative sides of the power source to energize the engine 28, which causes the rotation of the wheel 1 in the forward direction F at low speed. When it is necessary to stop the wiper blade 27, select position III. At this position, the motor brush 32 is connected to the positive side of the power source, and the negative brush side 33 has the power source through the block 34, containing the time delay controller and the relay, and the thumb switch 29. The relay of the block 34 is in the position shown in FIG. 5 by a solid line, and the limit switch 29 is in the position shown in FIG. 5 by a dashed line. As a result, the direction of the current passing through the motor 28 is reversed and the direction of rotation of the motor is reversed. After changing the direction of rotation of the reversing motor to the reverse, wheel 1 moves in the opposite direction, as indicated by arrow R in FIG. 3. When the wheel 1 moves in the opposite direction, the eccentric 5 rotates freely with respect to the crank pin 4 until the second stop 17 comes into contact with the second stopper 26. When this happens, the eccentric 5 will be restricted from turning with respect to the crank pin 4, as a result which, the eccentric and the finger will move together in a circular t-axis around the axis of rotation of the wheel 1. Due to the difference in diameters of the bearing surfaces of the finger 4 and the eccentric 5 and the bearing surfaces of the connecting rod 18 and eccentric 5, the difference in resistance The friction between the two pairs of bearing surfaces contributes to the relative angular movement between the eccentric 5 and the finger 4. This difference in friction resistance is increased by using the cup-shaped retainer 20 and the spring 21 pressing the connecting rod 18 to the flange 11 of the eccentric 5. As a result of the change stop 17 and thickening 12, the axis of the thickening 12 moves to a position that is outside the axis of the finger 4 of the crank relative to the axis of the rotation of the wheel 1, so that the radius of the crank increases and anovits Tij, as shown in FIG. 3. This gives an overall increase in the cleaning angle of the brushes 27 (FIG. 4, arc b). The limit switch 29 is located on the path of movement of the slider, which actuates it when it reaches the position corresponding to its lower limit of movement of the wiper blades npU and swing along the arc b. In this case, the limit switch 29 moves to the position shown in FIG. A solid line connects both brushes 32 and 33 of the engine to the positive side of the power source. This causes the engine to brake dynamically, causing the wiper drive mechanism to stop quickly, and. the wiper blades are laid in the initial park position P (Fig. 4). Depending on the moment of actuating the switch 30 by the driver relative to the angular position of the wheel 1, the wiper blades may or may not move to the upper limit of displacement before going down to the park position P. In the case where the wipers 27 of the wiper thus have to move, they move to the limit defined by arc b, and, therefore, are cleaned further / than they are usually cleaned during the reciprocating motion along arc d. This prevents the formation of undesirable stripes, which would have occurred if the brushes 27 were moved to the park position simply by shifting the arc a downwards. When the switch 30 is switched to position IV, the motor brush 32 connects to the positive side of the power supply source, and the relay of the unit 34 containing the time control knob and the relay is energized and moves to the position shown in FIG. 5 line by line. In this case, the brush of the electric motor 33 is connected to the negative side of the power source, and the engine starts to work in the opposite direction, so that either jogging can be performed (cleaning the windshield with one movement of the brushes) when the switch 30 is switched to position IV for some period or a time delay cleaning, in which the windshield cleaning is performed by single movements of the wiper blades with a predetermined time interval, set by the time delay regulator in block 34. In this mode, the torch works for an instant, and a full sweep is performed along the entire arc b with each movement. In the described embodiment, the arc b described by the wiper blades 27 at the course of the park position, is do more than the arc a at each end of the turn. The described device is simply constructive and relatively silent in operation. The frictional action of the latch 20 does not have the connecting rod 18 ensures that when the direction of rotation of the engine is reversed to the opposite relative movement between the eccentric 5 and the crank pin 4 from the first position to the second one, delays. Claim 1.
