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.
