Problems solved by technology

When braking, the piston of the brake cylinder stretches out, pushing the brake pads forward, and the friction pads on the brake pads rub against the brake disc to generate noise. The front end of the piston of the sub-pump has a very small contact area with the sound-absorbing plate, and the front end of the piston is also equipped with a central blind hole, so the material utilization rate of the sound-absorbing plate is not high, and it is wasteful
When replacing brake pads, the new brake pads often do not come with sound dampening pads as an accessory, and maintenance personnel often forget to install the old sound deadening pads on the new pads

Embodiment Construction

[0009] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0010] like figure 1 The shown brake cylinder piston with noise reduction function includes a body 1, a central blind hole 5 is provided at the front end of the body 1, and an annular groove 2 is opened on the inner wall of the central blind hole 5, and the front end surface of the body 1 is covered with The circular sound-absorbing sheet 3 is provided with a central through hole. In order to improve the effect of reducing noise, the front end surface of the circular sound-absorbing sheet 3 is corrugated (not shown in the figure), and the rear end of the circular sound-absorbing sheet 3 is evenly distributed in the circumferential dir...

Abstract

The invention discloses a brake cylinder piston with a noise reduction function. The brake cylinder piston with the noise reduction function comprises a body, the front end of the body is provided with a central blind hole, the inner wall of the central blind hole is provided with an annular groove, a circular silencing sheet covers the end face of the front end of the body, a central through hole is formed in the circular silencing sheet, the end face of the front end of the circular silencing sheet is provided with corrugation in a pressing mode, and four hook-shaped clamping pins which are clamped in the annular groove are evenly distributed on the circumference of the rear end of the circular silencing sheet.

Description

technical field [0001] The invention relates to a brake cylinder piston with noise reduction function. Background technique [0002] Automobile disc brakes include brake discs, brake pads, brake cylinders, etc., and brake pads include steel backs and friction plates fixed on the front of the steel backs. When braking, the piston of the brake cylinder stretches out, pushing the brake pads forward, and the friction pads on the brake pads rub against the brake disc to generate noise. The front end of the piston of the sub-pump has a very small contact area with the sound-absorbing plate, and the front end of the piston is also provided with a central blind hole, so the material utilization rate of the sound-absorbing plate is not high and is rather wasteful. When replacing brake pads, the new brake pads often do not come with noise dampening pads as an accessory, and service personnel often forget to install the old noise dampening pads on the new pads.
