Abstract

The invention relates to a kind of automobile brake, which changes the present symmetric brake hoofs into the brake with four brake hoofs superposing; two brake cams match with the brake hoofs; the leading screw nut device drives the two brake cams. It is characterized in that the brake air chamber connects the brake base plate through the connecting base; one end of the connecting base connects the air chamber and the other end connects the brake base plate; a inside screw thread is in one joint end of the connecting base and the brake base plate, and the screw lead angle matching with the inside screw thread is bigger than the self-locking angle; one end of the leading screw connects the push pole on the connecting base through the driving device and the other end joints the brake cam. The invention effectively ensures the stability of the contacting areas of the brake assistants and the brake moment, and improves the comprehensive stability and cooling capability of the brake system.

Description

technical field [0001] The invention relates to an improvement of an automobile brake, in particular to a drum-type four-shoe pneumatic automatic gap-adjusting brake. Background technique [0002] The braking system is used to slow down or stop the car while driving, to control the speed of the car when going downhill, and to stop on a slope. The safety of a car mainly depends on the working conditions of the steering system and braking system. The braking system should meet the basic requirements in four aspects: reliable braking force, easy handling, ensuring the stability of the braking system and good and reliable heat dissipation of the braking system. Existing drum brakes realize the purpose of braking by the contact friction resistance between the friction plates fixed on the brake shoe and the brake drum. During the braking process, due to the friction between the friction plate and the brake drum, wear will occur, which will change the contact area between the fri...
