Problems solved by technology

In the case where the inner and outer friction plates cannot be completely separated, the inner friction plate will always rub against the outer friction plate, causing the friction plate to heat up, and the higher the speed is, the more obvious the heat will be, which may cause the friction plate to burn out and reduce the braking efficiency of the brake , thereby reducing the safety of vehicle use

Abstract

The invention relates to the technical field of brake, and discloses a wet brake. The wet brake comprises a device body, a first flange, a second flange, a first piston, a second piston, at least one elastic element, a connecting mechanism, a first friction plate, a second friction plate and a pressing plate. According to the wet brake, the friction plates can be kept still in the driving state or in the braking state, the situation that due to the fact that the friction plates are connected to rotating elements, heating is caused by rotary friction of the friction plates in the driving process is avoided, and therefore the friction plates are prevented from being burnt out when rubbing each other, braking efficiency of the brake is ensured, and safety is ensured when a vehicle is used.

Description

technical field [0001] The invention relates to the technical field of brakes and is mainly applicable to wet brakes. Background technique [0002] Existing wet brakes are multi-disk full-disc brakes, mainly composed of outer friction plates, inner friction plates, pressure plate, piston, fixed element, rotating element, return spring and other parts. The outer friction plate and the fixed element are connected by splines, the inner friction plate and the rotating element are connected by splines, and the inner and outer friction plates are arranged alternately. Although the traditional wet brake also has the functions of driving and parking braking, the inner friction plate always rotates with the rotating element in the non-braking state. In the case that the inner and outer friction plates cannot be completely separated, the inner friction plate will always rub against the outer friction plate, causing the friction plate to heat up, and the higher the speed is, the more ...
