    An electrically assisted cycle wherein the electrical assistance is provided by an electric drive arrangement carried on the frame of the cycle and powered by a battery also carried by the frame. The output of the drive arrangement is coupled to the driven wheel of the cycle so that operation of the electric drive arrangement can propel the cycle. The drive arrangement is mounted on the frame for limited movement relative to the frame against the action of a resilient bias provided by rubber mounting bushes. An electrical switch is operated by movement of the drive arrangement relative to the frame and the electrical switch is arranged in the energizing circuit of the motor of the electric drive assembly. The switch is operated by movement of the drive arrangement from a rest position to a position wherein the rubber bushes are stressed. Until the switch is so operated the motor cannot be energized. Movement of the drive arrangement relative to the frame is effected by the rider applying driving force to the panel of the cycle. Thus until the rider of the cycle starts to propel the cycle by pedalling the electric motor cannot be energized to aid the rider. Similarly should the rider cease pedalling then immediately the motor will return under the resilient bias to its rest position and the motor will be de-energized by opening of the switch.

    1The invention relates to single-track vehicles and concerns auxiliary electric bicycles.
    The auxiliary electric drive bicycle contains a main drive, made in the form of driving and driven stars, encompassing an infinite inextensible flexible traction element, a power source mounted on the frame and connected to the auxiliary drive motor, the latter being kinematically connected to the main drive. , actuator, and manual control device containing motor switch, 1b
    The disadvantage of this bike is that it is set in motion only with the help of an electric motor and at every moment of time when moving, the cyclist must expend some effort to ensure the movement of the bike.
    The purpose of the invention is to provide automatic activation of the electric motor at the initial moment of movement.
    For this, the bike is equipped with an additional gear and an additional switch, one contact of which is mounted on the frame and the other on the electric motor, the output shaft of which is connected to the follower element of the additional gear and the driving element of this transmission is connected to the drive sprocket. and an additional gear transmission is mounted on the frame with the possibility of limited movement relative to it.
    FIG. 1 shows a bicycle, side view; FIG. 2 - part of the bicycle in FIG. I, enlarged view; in fig. 3 is a section A-A in FIG. 2
    The bicycle contains frame 1 made of metal pipes. A rear driving wheel 2 is installed on the back of the frame, and in front is a hand-held steering unit, and the lower part of which is the front running wheel 3, which is used to control the bicycle. Attach an asterisk 4 on which the non-stretch driver hopes is endless
    drive chain 5. This chain runs forward along the frame and wraps around a large-diameter drive sprocket 6 rotating on frame 1. The rotation plane of the sprocket 6 is parallel to the plane of the ragfl 1. Two pedals are attached to the eede 6 on either side of the sprocket with its diametrically opposite sides. Driving sprocket 4 may contain an overrunning clutch, so that the reverse movement of chain 5 does not affect the movement of a bicycle that has the ability to overtake the driving sprocket, for example, when driving downhill. To assist the driver in moving the bike, an electric motor 7 mounted on the frame and a battery of batteries 8 connected to it are also installed on the frame 1. The electric motor 7 and the additional gear 9, the body of which is rigidly fixed on the motor frame, form a single drive the node mounted on the frame 1. An additional gear transmission 9 transmits the rotation of the axis of the electric motor 7 to the leading gear element 10, which rotates in the same plane as the plane of the sprocket b and the chain 5 surrounding the sprocket 4. But in order for the auxiliary drive to be used only to assist the cyclist, and not to allow the bike to move without much effort on the driver’s side, an additional switch 11 is provided that controls the activation of the electric motor 7 be closed so that the motor 7 can operate. In practice, an additional switch
    11 is a microswitch designed for a relatively low current and not able to directly control the motor 7. In the preferred embodiment, the switch 11 controls the switching on of the relay with contacts for strong currents, and their current to the motor. In order for the AND switch to close,
    when the driver applies force to the pedals, the electric motor and additional gear are mounted on the frame with the possibility of limited movement, and the switch 11 is sensitive to this movement. For this, the electric motor 7 and the gear 9 are connected to the frame 1 by means of the first and second connecting elements 12 and 13. The element 12 is connected at one end with a bracket 14 mounted on the gear train 9, and on the other with a bracket 15, mounted on the frame. The element 12 is connected to the brackets 14 and 15 using rubber liners, whereby the connecting element 12 can be rotated relative to the brackets 14 and 15 due to the deformation of the rubber bush. Thus, the rubber liners allow rotational movement, but at the same time resist it with and provide an elastic displacement that returns the connecting element 12 to its original position relative to the brackets 14 and 15. The connecting sheeting 13 is connected at one end to the bracket 1b, and the other with the bracket 17 fixed on the element 18 of the frame 1. In an anesthetic way, the connection of the element 13 with the brackets 16 and 17 is carried out with the help of rubber inserts that allow
    5 turns of element 13 relative to
    koonshteyn, while at the same time providing an elastic displacement, returning the connecting element 13 to its original position relative to the brackets
    0 16 and 17.
    FIG. Figure 3 shows a cross section of a preferred joint between the element 13 and the bracket 17, but the structure of the other connections is similar to this. The connecting element 15 is made with two links 19 and 20. Between the links 19 and 20 there is a bracket 17 in which a hole 21 is made, longitudinally
    The Q axis of which is perpendicular to the plane of the frame 1. Inside the hole 21 is a hollow rubber insert 22, in which, in turn, is a sleeve 23. The axes of the hole 21
    5 and the sleeves 23 are the same, but the sleeve 23 is longer, so that its ends protrude on both sides of the bracket 17. In addition, the relative sizes of the hole 21, sleeve 23 and the rubber liner 22 are chosen so that the inner surface of the insert 22 is pressed to the outer surface of the sleeve 23 and its outer surface is pressed to the surface of the hole 21 of the bracket 17. Therefore, any attempt to rotate the sleeve 23 inside the bracket 17 meets the resistance of the liner 22 and deforms it, so that after the release of the sleeve 23 it returns to its original polo life when restoring the rubber liner 22. One end of each of the links
    19h 20 adjoins the corresponding axial end of the sleeve 23, and through the links 19, 20 and the sleeve 23 passes
    bolt 24. The head of the bolt attaches to the link 20, and the nut on its opposite end to the link 19, so that the bolt firmly presses the links 19 and

    20 to the protruding ends of the sleeve 23. Pressing prevents the links from moving over the sleeve 23, so that the only possibility of moving the element 13 relative to the bracket 17 is deformation of the insert 22, and after releasing the connecting elements they return to their original position under the influence of the insert 22. Similarly element 12 is connected to the bracket 14 and 15. In the absence of any external forces applied to the auxiliary electric drive, the latter is disconnected - elastic rubber inserts hold in the initial position relative to the frame 1. The case of the switch 11 is connected to the electric motor, and its rod is mounted on the connecting element 13. Any deviation of the auxiliary electric drive with respect to the frame 1, allowed by rubber inserts, will change the location of the auxiliary electric drive relative to the element 13, and this element will rotate relative to the frame 1. The device switch 11 provides that in the initial position of the auxiliary electric drive with respect to the frame 1 contact switch - are open, and the motor 7 is switched off. Because the drive chain 5 connecting the sprocket b and the sprocket 4 on the rear wheel, also hits the gear element 10, when the TP motor is off, the force applied by the cyclist to the sprocket 6 increases the tension of the upper part of the chain 5, i.e. where the chain is attached to the gear element 10. An increase in tension in the upper portion causes a force applied to the gear element 10, which tends to shift this element 10 to the sprocket b, which causes the auxiliary electric drive to move relative to frame I, allowed by the elements 12 and 13, causing resistance to rubber liners. At the same time, the auxiliary electric drive is scored relative to the frame 1; the switch body 11 is moved away from the element 13, the switch contacts, which makes it possible to turn on the electric motor 7. It is suitable to use the normal switch as the switch 11, which is open in the initial position of the auxiliary electric drive relative to ralfl 1 The switch 11 is not the only one that controls the electric motor 7, since it is desirable to have a manual control of the engine using the installed on the handlebars of the switch 24. Such a switch 24 may be connected in series with the switch II, so that to turn on the engine, the closed position of both switches is necessary. If the driver wants to set the bike in motion, he should close the manual control switch and start pushing the pedals. The initial application of the driving force of the pedal m displaces the auxiliary electric drive relative to the ramp 1, causing the switch 11 to close and turning on the electric motor 7. After that, the electric motor 7 helps the cyclist during movement and while the driver continues to apply the driving force to the sprocket 6 through the pedals, the electric drive remains in the shifted position and the switch 11 is turned on. But if the cyclist stops pressing the pedals, the auxiliary electric drive returns to its original position under the action of rubber inserts on the connecting elements 12 and 13, so that the switch 11 is opened and the electric motor 7 stops working regardless of the position of the manual steering switch. Obviously, if desired, the switch 11 may be de-activated when the auxiliary electric drive leaves the initial position; in this case, the electrical circuit must be arranged so that the opening of the switch 11 causes the electric motor 7 to close. It is advisable to provide the connection of the gear element 10 and the gear mechanism 9 with an overrunning clutch so that the sprocket B can overtake the gear element 10, for example, so that the driver can move the bike into motion without overcoming the resistance of the gear train 9.
