Description

Unpowered hydraulic damping device for large-sized automobile Technical Field The invention relates to the technical field of automobile assembly, in particular to unpowered hydraulic damping equipment for a large automobile. Background At present, a disc type or drum type friction braking mode is generally adopted in an automobile braking system, particularly a large automobile, and a strong retarding force is usually generated by means of contact friction between a high-pressure pneumatic driving brake shoe and a brake drum, so that the deceleration braking of the automobile is realized, however, the braking mode has obvious potential safety hazards in the actual transportation production process, especially when a large truck runs in severe road environments such as mountain roads, long slopes, steep slopes and the like. The frequent braking for a long time can cause overheat of the automobile hub or damage and locking of brake parts, so that the braking performance of the automobile is reduced, and even tire burst, accidents and the like of the automobile are caused when the braking performance is serious, thus endangering the life safety and property safety of personnel. In addition, in order to avoid the running safety accident caused by the heating of the brake drum, some users can privately refit the vehicle type, and the water tank is additionally arranged to spray water to cool the wheels, so that the method can temporarily relieve the heating phenomenon of the wheels, but the long-time spraying water can lead to water inflow between the brake shoe and the brake drum, the friction coefficient is reduced, even the braking is out of order, and the running safety risk is further increased. Meanwhile, the water tank is additionally arranged, so that the total load mass of the vehicle is increased, and overload and oil consumption are increased. More importantly, the existing friction braking mode enables a brake shoe and a brake drum of the motor vehicle to be vulnerable parts, the service life is short, the maintenance cost is high, and energy waste is caused by mass production of the parts. Although the existing automobile braking technology is mature, the potential safety hazard caused by high temperature generated by mechanical strong friction cannot be eliminated, and the high cost of the automobile in the processes of assembly, manufacture and use cannot be reduced.
