The present invention allows the vehicle to rotate by combining the reverse gear installed on the coaxial shaft with the reverse gear installed with a plurality of brake pieces which are inserted and detached on the driving bebe balance gear in the rear dehydrator driving the rear wheel by transmitting the engine power of the vehicle. When the vehicle is temporarily stopped while the vehicle is started on a sloped hill, the braking piece is pushed by the reverse gear to automatically prevent the car from going backward.In addition, the braking piece also stops when the car is turned off and parked. The present invention relates to a reverse automatic braking apparatus when stopping a hill of a vehicle, which is firmly pressed on the vehicle so that the vehicle automatically brakes forward and backward movements.

Conventionally, the brake pedal should be pushed by foot when stopping at a slope on a slope while driving a car.When starting the vehicle again on a hill, such as a pedal pedal, after pressing the brake pedal, the vehicle is not reversed quickly. If you are a beginner driver who has insufficient driving experience, you have to work hard to move forward. Many accidents had occurred.

Also, when the car is parked, the side brake lever inside the car is pulled to prevent the car from moving forward and backward by the inclined road surface. As the cable line of the cable was extended, the defect that could not function as the brake brake of the car occurred, and when the car was parked on the sloped hill, the car rolled back and forth, causing various accidents. It was inconvenient, such as having to stick to the wheels of each one.

The present invention has been devised to solve the above problems in view of the related art, and the structure, operation, and effect will be described in detail with reference to the accompanying drawings.

The driven bevel gears (9, 7 ') installed on the driving bevel gears (10) laid on the rear wheel shaft of the automobile are interlocked with each other, so that the case (8) is screwed together, and a plurality of protrusions ( 5 ') protruding drive rings 5 and 6 into the insertion section 3' 'provided in the braking piece 3, to be joined to the support piece 3', and to the reverse gear (1) (2). One end of the brake pin (3) is installed on the top of the brake to be detached with a spring (15), and the spring 12 is installed on the bonded dolphin (5 '') of the driving ring (5) (6) When the cylinder 11 and the reversing gear are operated, the solenoids 14, which are extended from the conducting line of the reversing indicator light, are installed in opposite directions, respectively.

In the drawings, reference numeral 13 denotes a suction nozzle.

After attaching the case 8 of the present invention to the vehicle's differential (rear defocus) to allow the driven bevel gear 10 to interlock with the driven bevel gear 10, the hill sloped while driving the car. When the vehicle is stopped by placing the accelerator pedal on the back and stopping the brake pedal, the engine's engine low speed is lowered. Therefore, through the suction cylinder 11 spoken to the suction nozzle 13 from the intake valve of the engine. Since the driving rings 5 and 6, which have been kept in a pulled state (see also the fourth (b) in the drawing), are returned to their original state by the elasticity of the spring 12, the reverse gear 1 by the protrusion 5 '. Since a plurality of brake pins 3 spaced apart from (2) are pinched on the reverse gears 1 and 2 by the elasticity of the spring 15 (see also FIG. 4 (a) in the drawing). Even if you don't press the brake pedal, you can prevent the car stopped on the slope. Since it is possible to advance the car by pressing the accessory pedal a little when starting the vehicle, it is possible to reduce the unnecessary consumption of fuel, and to prevent the collision with the rear car when the traffic is crowded. When the vehicle is parked with the engine turned off at a certain place after the operation of the vehicle, the suction force in the suction cylinder 11, which is addressed to the intake valve 13 to the intake valve of the engine, is extinguished. 6) is rotated in one direction by the elasticity of the spring 12 so that the dolphin (5 ') pushing the braking pieces (3) (4) to the outside run from the support pieces (3', 4 ') The brake pins (3) and (4) are inserted onto the reverse gears (1) and (2) arranged in opposite directions by the elasticity of the springs (15), which automatically brakes the forward and reverse of the vehicle. Cars move even in sloped places The driving ring is operated by the operation of the solenoid 14 installed from the conductor which lights the reverse indicator when the shift lever is operated in the reverse state by using the shift lever. (5) (6) is rotated so that the dolphin (5 ') integrally protruding from the driving ring (5) (6) pushes the support pin (3') of the braking piece (3) to the outside and the reverse gear (1 The braking pins (3) (4) that were inserted on the (2) is running, so that the reverse of the car is made.

As described above, the automatic reverse braking device of the present vehicle installs the case to the rear side of the differential so as to engage the driven bevel gears with the reverse gears alternately with the driving bevel gears built in the center of the rear wheel axle. During operation, the suction force of the external air sucked through the intake valve of the engine pulls the shaft of the suction cylinder through the suction nozzle, so that the driving ring rotates so that the brake piece is detached from the reverse gear so that normal operation of the vehicle is achieved. When the vehicle is stopped for a while, the engine's rotation speed (RPM) is significantly reduced, so the air suction force on the intake valve of the engine is also reduced. The braking piece is automatically shoveled on the reverse gear When the car is turned off and the engine is turned off, the air suction force on the intake valve of the engine is completely dissipated. Since the braking piece is squeezed firmly by the elasticity of the spring on the reverse gear, it is possible to firmly brake the forward and backward movement of the car, thus making it easier and safer to park the car on the inclined road surface. Since the gear oil is filled inside the case with the built-in reverse gear in contact with the side, it prevents the wear of the reverse gear and the braking piece, and prevents the noise generated when the brake piece is in contact with the reverse gear. Its simple structure makes it possible to mass production system. Since it can be used by attaching it to the same car's differential (rear de Hurenchal), it does not have to be troublesome and inconvenient to change the structure of the car, and its durability is excellent and its failure rate during use is long. It is a new useful practical design.

Claims (1)

The case 8 is screwed into place by allowing the driven bevel gear 9, which is mounted with tapered bearings 7, 7 ', to mate on a normal drive back gear 10 built on the center of the rear wheel shaft of the vehicle.
