Front disc brake chamber of truck brake system

Abstract

The invention discloses a front disc brake chamber of a truck brake system, which is provided with a diaphragm. The edge R surface of the diaphragm is clamped at R, connected with a cover assembly, of a shell assembly. The diaphragm is connected with one end of a push rod assembly. The other end of the push rod assembly has a ball head, and is extended out of the shell assembly. An air inlet is formed on the cover assembly. A resetting spring is arranged between the diaphragm and the shell assembly, and is sleeved on the push rod assembly. In the technical scheme, a common connecting way adopted by a drum brake chamber is changed, the shortcomings of the drum brake chamber are overcome, and the ball head of a push rod functions in guiding when moving in a pit of a lever of a brake so as to avoid swing and make more stable and comfortable the braking; a magnifying mechanism of the brake can produce high braking torque, so that a heavy truck running at high speed can be rapidly braked in short time to achieve high braking efficiency; and the front disc brake chamber still can work normally for long in severe natural environments, thereby prolonging the service life of the product.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and relates to the braking technology of construction machinery. More specifically, the invention relates to a disc-type front brake air chamber of a truck braking system. Background technique [0002] At present, the front brake air chambers used in most domestic construction machinery are drum brakes, which directly convert the air pressure into push rod force to achieve braking. There is no guide during the movement process, and the connecting fork drives the brake adjustment arm to move. There is a swing phenomenon, the performance is unstable, and the push rod force generated by the air pressure is directly determined by the size of the diaphragm and the air chamber housing, which cannot be amplified by the amplification mechanism, the braking performance is poor, and the service life is short. Contents of the invention [0003] The problem to be solved by the present invent...
