Problems solved by technology

On the one hand, the heat makes the mechanical structure of the brake heat up, and the heat caused will make the gap between the parts smaller, which is easy to cause interference problems; on the other hand, the gas in the hydraulic oil is heated and precipitated, and the air bubbles trapped in the hydraulic oil It will lead to problems such as poor movement and failure of the piston ejection
Eventually, the braking ability of the vehicle will decrease or even fail.

Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] Such as figure 1 , 2 The shown heat dissipation brake piston includes a piston rod formed by cold extrusion and a nose at the front end of the piston rod for connecting the brake block. The disc-shaped installation section 2 connected to the brake block and the heat dissipation section 3 located between the connection section 1 and the installation section 2, the heat dissipation section 3 includes a plurality of circumferential distributions that are conducive to supporting the stressed structure, and the two ends are respectively connected to the connection section 1 With the cooling columns 31 of the installation section 2 , the space between the plurality of cooling columns 31 forms a fluid passage 32 . When the brake is working, the contact and friction between the brake block and the wheel generates heat, which is transferred from the mounting section 2 to the h...

Abstract

The invention aims at providing a cooling brake piston. The cooling brake piston comprises a piston column and a nose part located at the front end of the piston column and used for being connected with a brake pad. The nose part comprises a connecting section fixedly connected with the piston column, a mounting section connected with the brake pad, and a cooling section located between the connecting section and the mounting section. The cooling section comprises multiple cooling columns with the two ends connected with the connecting section and the mounting section, and fluid passageways are formed in interval spaces between the cooling columns. By means of the cooling brake piston, heat generated by the brake pad can be effectively dissipated outwards at the position of the piston, conduction of the heat into an actuator body is reduced, thus, the effective working stability of a brake of a vehicle under the long-time working condition is improved, and the heat exhaustion failure status is reduced.

Description

technical field [0001] The invention relates to the field of automotive brake system components, in particular to a heat dissipation brake piston. Background technique [0002] In the brake caliper of the vehicle, the piston on it is pushed out by applying hydraulic pressure to achieve frictional braking with the hub of the vehicle. During the braking process, especially in frequent braking situations such as long downhill, the brake block connected to the front end of the brake piston will conduct the heat generated by friction to the inside of the brake. On the one hand, the heat makes the mechanical structure of the brake heat up, and the heat caused will make the gap between the parts smaller, which is easy to cause interference problems; on the other hand, the gas in the hydraulic oil is heated and precipitated, and the air bubbles trapped in the hydraulic oil It will lead to problems such as poor movement and failure of the piston ejection. It will eventually lead to...
