Problems solved by technology

In the above two braking methods, both the brake pads and the wheel drum or brake disc generate a large braking force through sliding friction. When the vehicle is running at low speed, it can brake safely, but when driving at high speed, in case of emergency, emergency When braking, the sliding friction force has a greater braking impact on the wheel drum or brake disc, and the car will also bear a greater impact and rush forward. Due to the sudden deceleration of the vehicle, it will still rush forward under the action of inertial force , prone to accidents such as rollovers, and easy to damage the brake device

Abstract

The invention discloses a hand brake mechanism of a motor vehicle, which comprises a brake drum and a brake disc, wherein the brake disc is sleeved with the brake drum; gear teeth are uniformly distributed on the inner circumference surface of the brake drum; tooth grooves are formed between the adjacent gear teeth; two support pins are fixed on the brake disc; two elastic steel plates are symmetrically arranged on the brake disc; one end of each elastic steel plate is articulated with each support pin; the other end of each elastic steel plate is free; a rotatable cam is fixed on the brake disc; the free ends of the two elastic steel plates are propped against the cam; extension springs are arranged between the elastic steel plates; brake shoes are fixed on the elastic steel plates; one end, far away from each elastic steel plate, of each brake shoe is articulated with brake rolls; and the brake rolls are matched with the tooth grooves of the brake drum in size. The brake mechanism can perform slow brake, prevents the vehicle from a traffic accident due to an overturn accident or brake system damage owing to inertia during emergency brake, slows down the vehicle gradually, and reduces the brake failure probability or provides response time for a driver to avoid the traffic accident.

Description

technical field [0001] The invention relates to a braking mechanism, in particular to a manual braking mechanism of a motor vehicle. Background technique [0002] At present, various commonly used brake mechanisms mainly adopt two types: disc brake mechanism and drum brake mechanism: disc brakes are equipped with brake pads on both sides of the brake disc driven by the wheel, and the brake pads are pushed by the sub-pump piston to clamp the brake pads on both sides. The drum brake mechanism is equipped with two arc-shaped brake pads in the wheel drum. Using the principle of leverage, the piston of the sub-pump pushes the brake pads into contact with the inner surface of the drum to generate friction and brake. In the above two braking methods, both the brake pads and the wheel drum or brake disc generate a large braking force through sliding friction. When the vehicle is running at low speed, it can brake safely, but when driving at high speed, in case of emergency, emergenc...
