Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like figure 1 As shown, the present invention provides a braking system of a light truck, including a service braking unit, a parking braking unit and an exhaust auxiliary braking unit. The service brake unit includes brake pedal assembly 1, vacuum booster and brake master cylinder assembly 2, oil storage cup 3, ABS valve body 10, first front axle brake assembly 5, second front axle brake assembly 11. The first rear axle brake assembly 8 and the second rear axle brake assembly 9. The brake pedal assembly 1 is installed on the body floor, the vacuum booster and brake master cylinder assembly 2 are installed on the brake pedal assembly 1, and the oil storage cup 3 i...

Abstract

The invention discloses a braking system of a light truck. The braking system comprises a service braking unit, a parking braking unit and an exhaust aid braking unit, wherein the exhaust aid braking unit comprises a vacuum pump, a vacuum electromagnetic valve and a vacuum tank which are connected with an outlet pipeline of the vacuum pump, and an exhaust butterfly valve connected with the vacuum electromagnetic valve; the vacuum pump is arranged on an engine; and the exhaust butterfly valve is arranged on an exhaust pipe. By applying the exhaust aid braking unit, when the truck runs in a long downgrade section, the working frequency of the service braking system can be reduced, abrasion and consumption of a service braking system material and abrasion of tyres due to braking are reduced, and braking deviation is reduced; by using an anti-skid brake system (ABS), the truck can effectively avoid the locked working conditions of the front and rear wheels under various working conditions; and by using front and rear bridge disc type brakes, the risk that the braking torque greatly declines can be avoided when the brake is overheated and soaked into water, so that the braking stability is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a braking system suitable for high-grade light trucks. Background technique [0002] At present, the braking system of domestic light trucks includes a hydraulic service brake unit and a central parking brake unit, and is rarely equipped with an exhaust auxiliary brake unit, and the hydraulic service brake unit uses front and rear drum brakes. Some models Equipped with hydraulic load sensing proportional valve. [0003] This braking system has the following problems: [0004] 1. Compared with disc brakes, drum brakes: poor heat dissipation; poor thermal and water stability of the brake; poor braking stability; during long-term and multi-frequency braking, the braking torque will be greatly increased Attenuation; and when the car is in forward and reverse driving states, there is a big difference in braking torque. [0005] 2. The load-sensing proportional valve can properl...
