Problems solved by technology

[0003] At present, the braking system of heavy-duty trucks is mostly based on drum brakes. In recent years, the caliper disc brake system (disc brake) has been gradually applied in the field of heavy-duty trucks due to its good heat dissipation and stability. However, the traditional The application of the caliper disc brake system on heavy trucks has inherent limitations such as limited braking torque potential and strict working conditions. Therefore, the existing caliper disc brakes are not widely used on heavy trucks, so there is an urgent need A disc brake with high braking force and good stability

Abstract

The invention provides a full-disc brake for a heavy vehicle. The brake comprises a base, a brake disc and an execution device for pressing a friction plate to the brake disc, wherein the base comprises a base cover body; a power input shaft in the execution device is mounted on the base cover body; the power input shaft extends into the base cover body from the outside of the base cover body towards the brake disc; the power input shaft is driven by an external rotating mechanism, and a first transmission part is arranged at the end, facing the brake disc, of the power input shaft; a middle driving piece is arranged in the base cover body and provided with a second transmission part; the middle driving piece is provided with a driving part which faces the brake disc and gradually rises towards the brake disc; a thrust frame and a plurality of ejector rods are arranged between the middle driving piece and the brake disc; one end of each ejector rod abuts against the driving part of themiddle driving piece, and the other end of each ejector rod abuts against or is fixed to the thrust frame; the ejector rods and the middle driving piece are configured in the manner that when the middle driving piece rotates; and the ejector rods are pushed by the driving part to move towards the brake disc.

Description

Technical field [0001] The present invention relates to the field of automobile braking, in particular to a full disc brake for heavy vehicles. Background technique [0002] A brake is a device that has functions such as decelerating, stopping or maintaining a stopped state of moving parts or moving machinery. Automobile brakes in the prior art generally include drum brake systems and disc brakes. Drum brake is a traditional braking system. To put it simply, drum brake is composed of hydraulic mechanism or pneumatic mechanism, brake shoes, brake pads and drum chamber. When braking, it is composed of hydraulic mechanism or pneumatic mechanism. The brake shoes exert force to press against the inner wall of the drum, and the brake drum is prevented from rotating by friction to achieve the braking effect. Disc brakes also use air pressure or hydraulic pressure as the power source. The main components include brake discs, air chamber or hydraulic mechanisms, brake calipers, friction...
