专利摘要:
A sensor responsive to the rate of change of changing rotational speeds of a rotatable element in which a flyweight is yieldably coupled with the rotatable element through an interconnecting element at any relative rotational position of the flyweight and interconnection for normal rotation thereof at a known ratio of rotational speed while accommodating decoupled rotation of the flyweight upon a change in rotational speed of the driving element at such a rate as to cause a torque in excess of a determinable threshold torque to act between the interconnection and the flyweight. During decoupled rotation, the flyweight is limited to deceleration at a controlled, substantially constant rate. Any occurrence of decoupled rotation of the flyweight is signalled as indicating that the rate of change of the changing rotational speed of the rotatable element exceeds a determinable rate. In the particular instance of an automotive vehicle wheel, the signalled occurrence indicates wheel slip and sensor signals may be used with an appropriate brake modulator for varying braking force.

The inertia load in the form of the flywheel 1 is rotatably mounted on the shaft 2 by means of appropriate bearings, for example rolling bearings. Outer ring 3 ball bearing

The engagement of two fingers 6 and 7 respectively on disk 4 and flywheel 1 limits the relative rotation of this flywheel 1 with respect to the disk 4 and the shaft 2.

shown by the arrow). The corresponding conductors microswitch 9 is connected to the sliding rings 11 and 12 and the corresponding
5 by brushes 13 and 14 so that microswitch-9 can transmit the corresponding ry brake module (not shown) with information related to the degree of change in the angular velocities of the shaft 2 and the rotating element (wheel) to which the shaft is connected. The sensor in FIG. 2 differs from the sensor in FIG. 1 by the presence of the rocker arm 15 to limit the relative angular positions in which the disk 16 and the flywheel 17 are connected. In particular, the rocker arm 15 has a protrusion 18 extending radially to the outside, which is enclosed between two fingers 19 and 20 protruding from the disk 16 in axial direction. In addition, the yoke 15 and the axial pin 21, coming out of the flywheel 17, are connected by a radially acting g initially adjusted spring 22, which holds the channel 1 in engagement with the two axial grooves 23 and 24 in the flywheel 17. The protruding from the flywheel 17 25 interacts with a pair of micro switches 26 to 27 in order to generate signals indicating that the speed is exceeded during both acceleration and deceleration.
The sensor in FIG. 2 is completely symmetrical. Consequently, when the threshold moment of rotation set by the spring 22 is overcome, the rocker arm 15 rises from the respective channels.

23 and 24, depending on the direction of the relative rotation of the disk 1 6 and the flywheel 17. In this case, the flywheel 17 rotates relative to the disk 16, causing the radial pin 25 to close one or the other microswitches 26 and 27.
The device in FIG. 3 is similar to the device in FIG. 2, but provides for an asymmetrical yoke 15, thereby providing a distinction between the degree of change, acceleration and the degree of change of inhibition. Such a possibility of differences in permissible threshold torque values is significant in sensors used on motor vehicles so that wheel slip does not reach dangerous values during braking and that excessive driving points are not attached. In a particular example of passenger vehicles, a reasonable torque limit value for a sensor that signals during braking, for example, is twice the torque threshold value for a sensor that signals during acceleration, in part because all four wheels act during braking and only two during acceleration.
Another modification of the sensor may include a hinged rocker 28 of FIG. 4) with a counterweight 29 designed to compensate for any action of centrifugal forces, as well as a beam 28 (FIG. 5) operating in a recess or groove 30 having different inclinations to distinguish the limiting torques.
The centrifugal means are preferably 101st the shape of a flywheel 31, (FIG. B) mounted for rotation relative to the drive means in the form of a shaft 32. The flywheel 31 in working condition is connected to the disk 33 by flexible means of communication for selectively disengaging and re-engaging, preferably in the form of a tape spirally wound on the circumferential surface 34 of the flywheel 31. The tape contains a spirally wound coil 35, the ends 36 and 37 of which are bent outward, forming two radially directed shoulders. Between the ends 36 and 37, a spring 38 is inserted to tighten the ends 36 and 37 towards each other.

To a friend, the functions of the spring 38 constitute the installation of a torsional control torque, which can be controlled by appropriate means, for example, by passing through one end 37 with a threaded screw 39:
It is desirable that the inner diameter of the coil 35 be slightly larger than the diameter of the surface 34 of the flywheel 31 in the absence of a bias force developed by the spring 38.
FIG. 6-11, the sensor has a pair of Axial pins 40 and 41 protruding from the disk 33 to interact with the One end 36 of the roller 35. This end 36 is normally held in retraction with the limiting fingers 41 by a force initially tuned by a spring 42 connected with the end 36 and the finger 40 (Fig. 8). This mode is characteristic of the sensor during rotation of the flywheel 31 and the disk 33 with a transmission ratio in angular velocity of 1: 1. A screw 43 passing through the pin 40 is provided for adjusting the initially tuned spring 42. As the braking force is applied to the corresponding vehicle wheel, the torque developed by the flywheel 31 relative to the disk 33 increases in the direction of the threshold value, the force developed by the initially tuned spring 42 caused one of the ends 36 to move toward the actuating finger 44 of the microswitch 45 (Fig. 9). By . As the vehicle wheel reaches the desired angular deceleration limit, the end 36 engages with the actuating finger 44 and changes the conductive state of the microswitch 45 so as to provide a signal to the electrically activated braking modulator (Fig. 10). With the continued excessive braking, the vehicle wheel tends to unwind the coil 35 against the force of the spring 38. While the end 36 is held up by the micro switch finger 44, the second end 37 moves (clockwise, as shown in Fig. 11), the flywheel 31 and disk 33 and resolving the relative rotation between them.
The disengagement of the flywheel 31 and the disk 33 continues until the angle
the wheel speed will not drop to a value less than the angular velocity of the flywheel, and while the opposite changes. The angular acceleration of the wheel will not restore the rotation of the disk 33 to the required gear ratio with the rotation of the flywheel 31.
When the rotational speeds return to the required gear ratio, the disk and flywheel re-clutch (Fig. 10) reappears, the flywheel is accelerated, moving the sensor from position to. FIG. 12 to the position in FIG. 8. The cycle of movements from the positions in FIG. 9 to the positions in FIG. 11 and back is then repeated as required during the course of the braking or until the vehicle stops.
It is assumed that while maintaining the above described operating principles shown in FIG. 6-11 devices can be modified. In addition, it is assumed that when the initially set threshold value of the torque is reached, a quick response of the sensor is ensured. Otherwise, it is advisable to prunshna
On the axial axis, a swing shaft 47 connected in working condition with an initial adjustment spring 42 and a torque control spring 38 with radially directed fingers 48 and 49. The rotation of the shaft 47 around its axis tightens and weakens a flexible element (preferably, synthetic,
Q non-expandable filament), performing the function of coil 35. The sensor action in FIG. 12 fully coincides with the operation of the sensor in FIG. 9-11.
The sensor (Fig. 14) has the same structural elements. The sensor in FIG. 14 differs from the sensor in FIG. 12; the fact that the rotation of the shaft 47 acts through the crank 50 on the shoe 51, withdrawing it from the engagement with the circular surface 34, flywheel 31. During operation of the sensor (Fig. 14), the engagement between the shoe 51 and the circular surface 34 is pulsing jammed

the action of which should move to a different approach to the fast repetition 36 when the microswitch was turned on, had very little or negative elasticity constant. It is desirable that as the end 36 moves from its normal position, the force rapidly decreases, developing when this end is limited. One solution to achieve this.
Multiple engagement and disengagement cycles is illustrated in FIG. 15, similar to FIG. 1, the sensor components are indicated by the same reference numerals. The difference between the devices in FIG. 15 and 1 is that between the flywheel 1 and the bearing element 52 for the radial pin 7, which
The test is to use mag Q to control the action of microswitching melodion to two relatively movable elements, such as a finger 41 and an end 36, with or without an additional spring 42. As soon as a small air gap appears between these elements (FIG. 9 ), then the effective restraint force quickly falls off.

By appropriately connecting an electromagnetic device 53 with a microswitch 9, the flywheel 1 can be disengaged and reconnected to the carrier element 52 to perform work in accordance with the present invention. Electromagnetic device 52 can also be used in combination with any of the devices in FIG. 2-5 and can be replaced by another clutch device under CONDITIONS, which will ensure the release and re-coupling with the required repetition frequencies.

The rotation of the shaft 47 around its axis tightens and weakens the flexible element (preferably, synthetic,
an inextensible thread) that performs the function of coil 35. The sensor action in FIG. 12 fully coincides with the operation of the sensor in FIG. 9-11.
The sensor (Fig. 14) has the same structural elements.

9, an electromagnetic device 53 is inserted. By appropriately connecting an electromagnetic device 53 with a microswitch 9, the flywheel 1 can be disengaged and reconnected to the carrier element 52 to perform work in accordance with the present invention. Electromagnetic device 52 can also be used in combination with any of the devices in FIG. 2-5 and can be replaced by another clutch device under CONDITIONS, which will ensure the release and re-coupling with the required repetition frequencies.
The means (Fig. 1b, the interconnecting shaft 32 (rotationally coupled with the rotating element, for example; the wheel of the vehicle) and the motor 713460388
Hovik 31 include a planetary gear-rotation of the orbital toothed gear 54, mounted on the sa 58, which is surrounded by the coil 35.
One of the ends 36 of the coil 35, which is mounted against the movement, engages the locking fingers 64 and 65, which are fixed relative to the rotating elements of the sensor. The elongated shafts 59 of the planetary serrated shaft 10 of the timber 56 are directly driven from the shaft 32. During operation, the flexibility of the interconnecting means is provided by rotating the orbital gear 58.
15 In FIG. 18 shows the following modification of the sensor in which rotating elements, for example a vehicle wheel and a flywheel, normally rotate with a known transmission ratio of 1: 1. A microswitch 45 is mounted on a disk 33, which rotates with a shaft 32 operatively associated with a rotating member, such as a wheel of a vehicle 25. With this arrangement, the microswitch and interaction with one of the ends 36 of the belt mounted on the rotatable element 60, which engages the planetary gear 56, comes with the coil 35 of the belt. In addition to the ZO flywheel 31 can be fixed from the rear, the rotating element 60 is mounted relative to the intermediate shaft 55, dp of rotation relative to the shaft 32. while the operation is provided, the tape has a pair of radially running qi in accordance with the invention, ends 36 and 37 and a bias spring 38. Another variant of the sensor that is acting between them. One of the combinations of certain features of the sensors 36 is fixed relative to the disk 61 of the forks in FIG. 17 and 18, shown in a pair of axially extending fingers 62 of FIG. 19, where the structural members and 63. ts similar to the structural members of the handwheel 31 are normally given in FIG. 18 are denoted by the same rotation with known gear from-to numbers. The difference between the angular velocity gearing in FIG. 18 and 19 consists in mounting whose rotation from shaft 32 through coil fingers 5 and 6 and microswitch 45
motionless relative to other elements of the sensor, thereby eliminating
the interconnecting shaft 55 for transmitting rotation to the disk 33 on which microswitch 45 is mounted, having a working finger 44. The flywheel 31 has a radially protruding finger 7 normally biased in engagement with the restricting finger 6 of the restrictive spring 8 that connects the radial finger 7 with the second finger 5, leaving the disk 33.
The planetary gear 54 additionally has three planetary gears 56, each of which is engaged with both the sun gear 57 and the orbital gear 58. The orbital gear 58 is braked, while the planetary gears 56. in rotation with a soft coupling. In particular, each of the planetary gears 56 is mounted on a corresponding protruding shaft 59 extending from the ribbon-enclosed element 60. The element 60 defines a circular surface 34 which is the hook 35 of the belt, the rotatable element 60, the planetary gear 54 and the interconnecting shaft 55. One of the preferred is the need to use sliding
rings or the like.
Limiters acting on one of the ends 36 of the coil 35 5: 1 sensor. In the case of operation in accordance with FIG. 12-20, when operating with a sequence of events, 50 a significant acceleration of the flywheel gear ratios relative to the rotation of the vehicle wheel is a sign that was indicated when referring to FIG. 6-11, a flexible connection is established between the rotating member 60 and the disk 61, which are normally coupled by a tape reel 35.
FIG. 17 shows a modification of the sensor in FIG. 16. The difference between the sensors in FIG. 16 and 17 is that it is possible
ka with unlimited torque rotates when re-coupling. In the examples where planetary gears are used, the invention assumes that by effectively limiting the transmitted torsional moment, the planetary gear is protected. This design is shown in FIG. 20.

The sensor in FIG. 20, generally along with one of a pair of hooks 68 and 69. The fitting of the sensor in FIG. 16, and therefore the gins 70 and 71 of the initial installation, the elements to be compared are indicated by the same 1 positions. The design differences are the installation of the limiting pin 63 and the acceleration limiting spring 66, acting between the tape end 36 and the finger 63. During operation, the sensor (Fig. 20} functions like the sensors described above to the point where the accelerating rotating element or wheel the means do not reattach to the flywheel. When re-engaging, the end 36 of the tape is retracted from the stop pin 62, while the second end 37 moves towards the stop
finger 63. As the torque develops, the flywheel 31 tends to rotate and is sufficient to overcome the force developed by the spring 66, the other end 3.7 meshes with the finger 63, allowing the ends 36 and 37 to be disengaged.
Accelerating torque control is also acceptable for the sensors shown in FIG. 22 and 23, at
The second normal gear ratio of the balance bar includes the first and second shifts is 1: 1. Sensor elements to ground. The first mass is the flywheel 31 discussed above. However, it has been fixed to it by means of appropriate fastening means. 22 and 23, corresponding to the elements described above, are denoted by the same positions. The sensor (Figs. 22 and 23) uses spring 66 to perform 35 of the stepping part 77. At the protruding function provided by the fingers and part 77 there is a ball bearing 78, etc. in the gauges of the previous figures. With. On which the second spring is mounted, one and one springs 67 and 66 are executed by the driver 79. By means of corresponding with open side hooks of the freewheel sprocket, preferably. (Fig. 23) to provide, relatively, in the form of a spiral wound twist and end 36 in one. coil 80 attached with a single board. The spring 66 is preferably made with an internal voltage and more rigid compared to the spring 67.
Another form of the sensor is shown in FIG. 21 and is designed to operate both an acceleration sensor and a braking sensor, which functions in both directions of rotation of the flywheel 31 with respect to the rotation of the disk 33. Elements that are common to the sensors considered above are indicated by the same positions.
The flywheel 31, together with the coil 35, is able to turn a small angle in either direction relative to the disk 33 until one of the ends 36 and 37 of the coils stops the coils at the ends 36 and 37 through the hooks 68 and 69 and are clamped between
corresponding washers 72 and 73 and brackets 74 and 75. Threshold moments for sensing acceleration and deceleration can be adjusted to different values in two directions of relative rotation by selecting different forces developed by two springs 70 and 71. Springs 70 and 71 are under preliminary tension gom
using locking means in the form of washers 76. However, the inertia of the flywheel 31 is the same in both directions.
In some applications, for example, with vehicles having automatic systems such as dL braking control and acceleration control, it is advisable to have excellent adjustments to the sensing acceleration and braking not only with respect to adjusting the spring force, but also with respect to inertial adjustments . One example of such a differentiation in inertial adjustments is shown in FIG. 24, - where
The protruding part 77 is fixed. The protruding part 77 has a ball bearing 78, on which a second flywheel 79 is mounted. By means of a corresponding one-way clutch, preferably in the form of a helically wound coil 80, attached at one end to the second flywheel 79, the first and second masses are operatively coupled with each other for rotation with a common angular velocity in one direction and operatively disengaged for rotation of only one mass in the opposite direction.
