The purpose of this utility model be for the above-mentioned problems in the prior art, provide a kind of operating noise it is low,
The preceding brake caliper piston of the timely return of brake(-holder) block can be driven.
The purpose of this utility model can be realized by the following technical scheme: a kind of preceding brake caliper piston, including be in cylinder
The ontology of shape, the top surface of the ontology offer the blind hole with ontology coaxial arrangement, which is characterized in that the bottom of the ontology
Face is fixed with several circumferentially uniformly distributed rubber parts, and each rubber parts protrudes from the setting of ontology bottom surface and each rubber parts protrudes
The height of ontology bottom surface is consistent, and the ontology has the interconnecting piece for connecting with brake(-holder) block.
Rubber parts protrusion ontology bottom surface setting in brake caliper piston, avoids being formed between ontology bottom surface and caliper bottom before this
Vacuum state, brake fluid can rapidly enter between ontology bottom surface and caliper, ensure that braking effect, and when ontology return,
Rubber parts plays buffering noise reduction effect, avoids the generation of touch noise, and in addition interconnecting piece makes brake(-holder) block be connected with ontology, makes
Brake(-holder) block with ontology timely return together, avoid brake(-holder) block heel and toe wear, extend service life.
In a kind of above-mentioned preceding brake caliper piston, the bottom surface of the ontology is equipped with coaxially setting and recessed appearance
Liquid bath, the rubber parts are uniformly distributed around liquid bath is held.Hold liquid bath and provide accommodation space for brake fluid, so that the system of ontology bottom surface
Hydrodynamic will not lack, and while ensure that braking effect, also ensure the circulation of brake fluid, play heat spreading function.
In a kind of above-mentioned preceding brake caliper piston, periphery wall of the ontology close to bottom surface has one section of undergauge section,
The outer diameter of the undergauge section is less than the outer diameter of ontology, and the height of the undergauge section is the body height of one third.Undergauge
It is flowed between section and caliper inner wall for brake fluid, guarantees that brake fluid sufficiently to improve braking effect, and convenient for brake fluid flowing, mentions
High thermal diffusivity.
In a kind of above-mentioned preceding brake caliper piston, the interconnecting piece is what ontology had on the periphery wall of top surface
External screw thread.Brake(-holder) block is connect with external screw thread, to be displaced together with ontology.
In a kind of above-mentioned preceding brake caliper piston, the top surface of the ontology has one to enclose the gear radially-inwardly turned down
Side.Rib increases the contact area of body top surface and brake(-holder) block, so that positioning is steady between the two after ontology is connect with brake(-holder) block
Gu.
As another situation, in a kind of above-mentioned preceding brake caliper piston, the interconnecting piece has for inner body wall
Internal screw thread.Brake(-holder) block is connect with internal screw thread, to be displaced together with ontology.
In a kind of above-mentioned preceding brake caliper piston, the periphery wall of the close top surface of the ontology has to be drawn a circle to approve for sealing
The annular groove of position.Facilitate the installation of sealing ring in this way.
In a kind of above-mentioned preceding brake caliper piston, the bottom edge of the ontology has the conical surface, the conical surface two
Side passes through round-corner transition.Guiding role is played in the setting of the conical surface and fillet, facilitates installation, and ensure that brake fluid circulation
Fluency.
In a kind of above-mentioned preceding brake caliper piston, the rubber parts rectangular-blocklike and rubber parts is in length direction
Extended line is arranged perpendicular to body axis, and the quantity of the rubber parts is eight.Such stabilized structure can guarantee ideal slow
Rush noise reduction effect.
Compared with prior art, brake caliper piston circulates before this convenient for brake fluid, good braking effect, and energy and brake(-holder) block
It is connected, so that brake(-holder) block is displaced together with ontology, avoids brake(-holder) block heel and toe wear, extend service life, work nothing is made an uproar
Sound, good operating stability.
