Problems solved by technology

[0003] In order to overcome the deficiency that the existing braking device cannot select the braking direction, the present invention proposes a braking device capable of selecting the braking direction. When the vehicle slips backwards, the brakes are actively performed, and when the vehicle is moving forward, the brakes are automatically released.

Abstract

A slippage preventing system for vehicular hill starting is mounted on an axle of driven wheels by a one-way brake starter through a support. The one-way brake starter comprises a ratchet wheel, a flywheel in a pawl structure or a ratchet-gear wheel in a shell, a rack push rod meshed with the flywheel in a pawl structure or the ratchet-gear wheel and a return spring on the rack push rod and a truckle, mounted on a same shaft with the flywheel or the ratchet-gear wheel, outside the shell. The slippage preventing system is controlled by a hydraulic passage or an inhaul cable connected with the same and disposed in a cab. During hill starting, the truckle is combined with a rim part of a brake disk or a hub, when slippage occurs, the rotating rim of the brake disk or the hub drives the truckle outside the shell and the flywheel or the ratchet-gear wheel in the shell to poke the rack push rod outwardly so as to compress an auxiliary brake pump piston at the position, braking is achieved by the aid of the hydraulic passage connected with the auxiliary brake pump and a driven wheel brake caliper or an auxiliary brake caliper, and braking stops when a vehicle advances.

Description

Technical field [0001] The invention relates to an automobile brake, which can realize one-way braking and prevent the vehicle from slipping backward under the control of the driver when starting on a slope. Background technique [0002] At present, the known vehicle braking device cannot select the braking direction, and vehicles other than automatic transmission must be started on a hill with the cooperation of the hand brake, clutch and accelerator pedal. When the cooperation is not good, the vehicle will slip backwards, the engine will stall, causing traffic jams and even traffic accidents. Contents of the invention [0003] In order to overcome the deficiency that the existing braking device cannot select the braking direction, the present invention proposes a braking device capable of selecting the braking direction. When the vehicle slips backwards, it actively brakes, and when the vehicle moves forward, the brake is automatically released. . [0004] The technica...
