Problems solved by technology

Currently commonly used resin-based friction materials have excellent friction and wear properties, light weight, less braking sparks, and good braking effects, but have poor thermal conductivity and difficulty in dissipating braking energy. The biggest problem is that the thermal recession is severe, resulting in reduced braking efficiency

Abstract

The invention discloses a disc brake adopting a novel brake material for a load-carrying vehicle, and relates to the technical field of automobile brakes. The disc brake comprises a brake disc, a semicircular brake caliper, and a parking disc which is connected with an in-vehicle handbrake. The disc brake is characterized in that conical brake bodies are mounted on two end surfaces of the brake disc; an arc rack is arranged at the bottom of a work station slot; a brake block A is arranged on two end surface of the upper part of the work station slot, a hydraulic cylinder is arranged at the end corresponding to the right end of the upper part of the work station slot; a brake block B is arranged at the left end of a brake piston; the surfaces, opposite to the brake bodies, of the brake block A and the brake block B are matched with the shapes of the surfaces of the brake bodies; a sliding slot is formed in the right end of the brake caliper; the sliding slot is in sliding fit with a sliding pin nail; the sliding pin nail is fixed on a vehicle frame; a horizontal control tank is arranged on one side of the lower part of the brake caliper; and a support rod is arranged on the parking disc and is connected with the control tank in a sliding manner. The disc brake has the beneficial effects that the shape of a conventional brake disc is optimized, the brake effect is improved, the parking is relatively stable, and clearance adjustment is relatively simple.

Description

Technical field [0001] The invention relates to the technical field of automobile braking. Background technique [0002] The rear disc brake is the brake execution device in the car and mini car brake system, and is a key component in the car brake system. Its working principle is to use the hydraulic pressure generated by the brake master cylinder assembly, which is transmitted to the rear brake caliper body through the brake pipeline, so that the brake pads and the rear brake disc contact and generate frictional resistance to prevent the rotation or rotation of the wheels. trend. The rear disc brake has more components than the drum brake, and can integrate the emergency braking system and the parking brake system into the brake caliper body, so the structure is more compact and the maintenance is more difficult, but the rear brake caliper is relatively The advantages over the rear drum brake are also obvious. The braking efficiency is stable, the brake balance is good, the h...
