Abstract

The utility model provides a kind of brake caliper piston, belongs to technical field of automobile accessories.It solves the problems such as existing brake caliper piston matter weight, poor heat radiation.This brake caliper piston includes cylindrical body, one end of body offers the connection blind hole being coaxially disposed with body, the other end of body offers several radiating blind holes, and radiating blind hole is circumferentially uniformly distributed around the axis of body and the blind hole that radiates at least is deep at the half of body.The utility model has the advantages that in light weight, thermal diffusivity is good and structural strength is good.

Description

A kind of brake caliper piston
Technical field
The utility model belongs to technical field of automobile accessories, is related to a kind of piston, more particularly to a kind of brake caliper piston.
Background technology
Hydraulic brake caliper generally comprises caliper, brake(-holder) block, piston, and piston promotes brake(-holder) block to abut in brake disc to realize Braking, in order to which braking effect is preferable, is all promoted respectively on present vehicle in caliper using symmetrically arranged two pistons Brake(-holder) block.
Existing brake caliper piston one end has cavity, and the other end is blind end, its heavier-weight, if piston wall thickness is subtracted It is small, though energy loss of weight, structural strength decline and shorten service life, and in braking procedure, heat caused by braking It is not easy to distribute, brake fluid temperature can be caused to raise, cause brake efficiency to decline, the discharge of piston chamber air is not prompt enough in addition, Cause air pressure rise too fast and cause brake fluid to leak.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of structural strength is good, The good brake caliper piston of in light weight and thermal diffusivity.
The purpose of this utility model can be realized by following technical proposal:A kind of brake caliper piston, including it is cylindrical Body, it is characterised in that one end of described body offers the connection blind hole being coaxially disposed with body, described body The other end offers several radiating blind holes, and described radiating blind hole is circumferentially uniformly distributed and described scattered around the axis of body Hot blind hole is at least deep at the half of body.
This brake caliper piston is convenient to be connected with adjusting screw rod by connecting the setting of blind hole, by the setting for the blind hole that radiates, The weight of body is alleviated, and without wall thickness is made into frivolous, the structural strength of body is ensure that, in addition in braking procedure In, heat is distributed by the blind hole that radiates, and brake fluid temperature will not be caused to rise, be ensure that brake efficiency.
In a kind of above-mentioned brake caliper piston, described body radially offers steam vent, the connection of described steam vent At the bottom hole of connection blind hole.Steam vent is easy to discharge air, avoids air pressure rise too fast and causes brake fluid to leak.
In a kind of above-mentioned brake caliper piston, a ring annular groove, described steam vent are offered on described body Aperture be located in described annular groove.The setting of annular groove expands exhaust space, smooth in exhaust.
In a kind of above-mentioned brake caliper piston, described body has a circle coaxial with body in the end of radiating blind hole Set and axially projecting bulge loop, described bulge loop surround described radiating blind hole and set.The setting of bulge loop avoids installation from interfering, Also so that the region that bulge loop surrounds forms heat-dissipating space, it is easy to radiate.
In a kind of above-mentioned brake caliper piston, described body is provided with fillet in the edge of the end of connection blind hole.This Sample fillet plays guide effect, is easy to body to install.
Compared with prior art, the structural strength of this brake caliper piston is high, and in light weight and easy for installation, thermal diffusivity is good, Avoid brake fluid temperature from raising and influence brake efficiency, smooth in exhaust, avoid air pressure rise too fast and cause brake fluid leakage.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this brake caliper piston includes cylindrical body 1, and one end of body 1 offers and this The connection blind hole 2 that body 1 is coaxially disposed, the other end of body 1 offer several radiating blind holes 3, and radiating blind hole 3 surrounds body 1 Axis be circumferentially uniformly distributed and the blind hole 3 that radiates at least is deep at the half of body 1.
Further describe in detail, in the present embodiment radiate blind hole 3 quantity be six, radiating blind hole 3 be deep to body 1 three/ At two.Brake fluid is caused to leak in order to avoid air pressure rise is too fast, the radial direction of body 1 offers steam vent 4, and steam vent 4 connects At the bottom hole of connection blind hole 2, a ring annular groove 5 is offered on body 1, the aperture of steam vent 4 is located in annular groove 5.
In order to avoid installation interference and it is easy to radiate, body 1 has a circle coaxial with body 1 in the end of radiating blind hole 3 Set and axially projecting bulge loop 6, bulge loop 6 surround radiating blind hole 3 and set;For the ease of installation, body 1 is in connection blind hole 2 The edge of end is provided with fillet 7.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
