    This device, which is intended to brake a wheel of a vehicle rotated by a drive shaft carrying at its free end an epicyclic train reducer housed in a casing, is characterized in that it is fixed on the outer face of the bottom of the casing and comprises a watertight case enclosing at least one friction disc interlocked in rotation with the sun wheel of the reducer, as well as an annular plate for moving the disc axially and applying it against at least one internal friction surface, this plate being itself axially movable towards the disc under the action of control means situated inside the casing.

    The invention relates to the automotive industry, in particular to drive wheel drive mechanisms.
    The closest to the proposed g technical solution is the drive wheel drive mechanism of the car, which contains a drive shaft protruding from the bridge girder, a planetary gear, the sun gear that is mounted on the drive shaft, the crown gear connected to the holder the bridge, and the satellites are mounted on axles fixed in the end wall of the closed crank case of the crankcase connected to the hub, while a sealed box is attached to the outer side of the indicated wall A brake device 20 consisting of a brake disk connected to the drive shaft and a pressure disk for pressing the brake disk under the action of the brake actuator to the friction surface is placed
    on the end wall of the hermetic box 1,
    However, the mechanism has inadequate operational reliability, complex construction and considerable size.
    The purpose of the invention is to increase operational reliability, simplify maintenance and reduce size.

    Claims (3)
    [1]
    This goal is achieved by the fact that the satellite axes are hollow, and the brake actuator is made in the form of pushers, passed through the specified axes and abutting the pressure disk, placed inside the ring holder connecting the free ends of the pushers, the rotary ring plate, installed with the possibility of axial movement and press against said ring, returnable elastic means, two-arm swinging levers fixed on a non-rotatable ring plate and contacting with one arm only by the holder, and each they are the ssilovye nodes of the brake drive. Cavities are made in the end wall of the crankcase, and the returnable means are made in the form of springs installed in the said cavities and fixed by machines in contact with the ring. The holder has holes with edges in contact with the shoulders of the two shoulders, on which the cam surfaces are made. Grooves are made in the holder, and the brake actuator assembly is made in the form of an annular element freely mounted on the bridge beam and equipped with pushers passed through the groove in the holder and in contact with the shoulders of the double shoulders, the annular element being in contact with the piston a hydraulic cylinder mounted on a bridge beam. I The drawing shows the drive mechanism for driving a car. The mechanism contains a drive shaft 1 placed in beam 2 of the bridge, a planetary gear including sun gear 3, mounted on the free end of shaft 1., and satellites (one of which is visible in the drawing), interacting with the ring gear 5 connected to the holder 6, mounted on beam 2. The satellites are mounted on axles 7 fixed in the crankcase 8, rotating with the wheel hub 9 mounted rotatably on beam 2 on two bearings 10 and 11. The brake device is mounted on the outer side of the crankcase and extends from the outside to forest. It contains a sealed box 12, closing the brake disk 13, rotating from gear 3 and a pressure disk 14, designed to move the disk 13 in the axial direction and press it to the inner friction surface 15. The box 12 may contain several disks located between internal friction surfaces The brake actuator contains pushers 16 placed in axles of 7 satellites. The pushers are supported on the disk 14 by one of their ends, and the other end is riveted in a ring 17 placed inside the holder 6. In addition, the brake actuator contains. a rotary ring plate 18 located behind the ring 17 and pressed against it in order to overcome the action of the return springs 19 under the influence of the double-arm swing arms 20 (the drawing shows one of them to move the disk 14o) Each of the springs 19 rests on the bottom of the cavity 21 made in the inner wall surface of the crankcase 8, and on the plate 18, on which glasses 22 are provided for this purpose. The two shoulders levers 20 are mounted with the possibility of swinging on the legs of the plate 18, to which they are pressed against the cam surface 23, and From the ends, they are pressed against the edge of the hole 24 in the holder 6. The number of double-arm levers does not necessarily equal the number of satellites. For stability, their number can be three. The brake actuator assembly also contains an annular element 25 mounted slidably on the beam 2. and carrying pushers 2b, the free ends of which each rest on the end of a two-armed lever that does not rest on the edge of the hole 24, as well as an annular cylinder 27 mounted on the beam 2, the piston 28 of which acts in the direction opposite the action of the return spring 29, to move the pusher 26 to the double-shouldered levers. Pushers 2b pass through bores made in the rear part of the holder 6, on which the ball bearing 11 is supported, and the piston 28 moves under the pressure of brake fluid flowing into the cylinder 27 through channel 30 in the sleeve 31 bearing the ball bearing 10. Brake fluid is supplied through the hole 32, made in the back of the sleeve 31, and the blowing is carried out through a channel (not yet shown in the drawing) located at the top of the cylinder 27. The mechanism contains two sealing gaskets 33 and 34 that do not let moisture through active braking of the box 12. They can be excluded in the event that the work is intended to brake the gear oil. . The mechanism works as follows. When the driver presses the brake pedal, the brake58 on the fluid through the channel 30 penetrates the cylinder 27 and puts pressure on the piston 28 acting on the element 25. The latter moves in the direction of the arrow F, and the pushers 2b turn the two shoulders 20 on their support in the holes x 2 of the holder 6. Two-arm levers 20. with their cam surface 23 press plate 18, to ring 17 which transfer pressure in the direction of arrow F to the pushers 16 "Disc 14 presses against disk 13, which in its The sequence is pressed to the friction surface. The wheel is thus braked and the braking reaction is received by the crown gear, which transfers it to the beam 2 through holder 6. The design described allows to increase the reliability of the drive wheel drive mechanism of Invention 1. A drive wheel drive mechanism containing a drive shaft protruding from the bridge girder, a planar gear, the sun gear of which is mounted on the drive shaft, the crown gear is connected to a holder rigidly connected and the satellites are mounted on the axles fixed in the end wall of the crankcase closing the planetary gear unit connected to the hub, while an airtight box is attached to the outer side of the indicated wall, in which the braking device is placed; the drive shaft and the pressure plate to press the brake disk under the action of the brake actuator to the friction surface on the end wall of the sealed box, characterized in that, in order to increase the operational hedgehog 36 simplify servicing and downsizing, the satellite axes are made hollow, and the braking drive is made in the form of pushers, passed through the indicated axes and abutted on a pressure disk, placed inside the ring holder connecting the free ends of the pushers, a non-rotating ring plate that is axially mounted displace and press against the ring of, recurrent elastic means, two-arm swinging levers fixed on a non-rotating ring plate and contacting with one shoulder with elem, and others - with the force of the brake actuator assemblies.
