Long-service-life and wear-resistant wheel disc type brake device of truck, formula and manufacturing process of wheel disc type brake device

Abstract

The invention relates to the technical field of truck braking, in particular to a truck wheel disc type braking device long in service life and resistant to abrasion and a manufacturing process thereof.The truck wheel disc type braking device comprises a back plate and is characterized in that a silencing plate used for silencing in the braking process is installed on one side of the back plate, and a plurality of braking mechanisms are arranged on the back plate; the brake mechanisms are fixedly connected with the back plate through fixing mechanisms, cooling mechanisms are arranged on the back plate, the silencing plate and the brake mechanisms, a control mechanism is installed on one brake mechanism, and the cooling mechanisms are connected with the control mechanism. Wherein one braking mechanism is provided with the buffering mechanism, when a driver steps on the brake pedal, the braking mechanisms abut against the discs at the positions of the wheels, braking is achieved, the control mechanism abuts against the discs while braking is conducted, water leakage of the control mechanism is controlled, heat dissipation of the braking mechanisms is achieved, and loss of a brake assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of truck brakes, in particular to a long-life and wear-resistant large truck wheel disc brake device and a manufacturing process thereof. Background technique [0002] Automobile braking system refers to a series of special devices that exert a certain force on certain parts of the automobile (mainly the wheels) to perform a certain degree of mandatory braking. The function of the braking system is to make the driving car decelerate or even stop forcibly according to the driver's request; the disc brake on a large truck is composed of a brake oil pump, a brake disc connected to the wheel and a brake caliper on the disc. .When braking, the high-pressure brake oil pushes the piston in the caliper, and presses the brake shoe against the brake disc to produce a braking effect. [0003] However, at present, when large-scale trucks are transported, they need to brake for a long time on the continuous downhill sec...

AI Technical Summary

Problems solved by technology

[0003] However, at present, when large-scale trucks are transported, they need to brake for a long time on the continuous downhill section. During the braking process, the temperature of the brake pads will rise, the friction body will be gradually consumed, and the brake pads need to be replaced frequently. The friction plate is usually a whole piece and is not set separately. When the friction plate is partially worn, the entire friction plate and the back plate need to be replaced, which wastes resources and is inconvenient to operate. When the brakes are used for a long time, the temperature of the brake pads will Higher, in the existing way of heat dissipation of the brake pads, the driver regularly pours cold water directly to scatter the heat, and there is no cooling mechanism on the back plate, which is not conducive to the heat dissipation of the brake pads, and the loss is large
