Description
Technical field
The utility model relates to a kind of piston, especially a kind of piston with returning quickly function.
Background technique
Piston is a kind of component for moving back and forth in cylinder body, and piston is usually used in multiple devices on automobile, than
Such as brake callipers, the braking effect of brake callipers just extremely relies on piston, after brake callipers are fixed by braking bracket,
To be pushed up outside the piston of itself using hydraulic oil, the friction block being connected at this time with piston will withstand on brake block, reach deceleration or
The effect of brake does not need after slowing down or braking, piston driving friction block return, and the return of piston is by being installed on piston
The rectangular seal in annular groove on body is come what is completed, and when pushing up outside piston, flexible deformation can occur for rectangular seal, finally
Rectangular seal can be by natural resiliency by piston reset, but rectangular seal is all rubber material, after long-term use, pole
The case where being easy to happen aging or flexibility missing, cause piston easily there is a situation where return is slow or can not return, if brake
Caliper piston return it is slow or can not return, the problem of brake callipers can then drag brake, jeopardize traffic safety, not can guarantee row
The personal safety of vehicle personnel.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of pistons with returning quickly function, it can be in rectangle
The case where sealing ring aging or flexibility missing, still can guarantee brake callipers piston returning quickly.
The technical scheme in the invention for solving the above technical problem are as follows:
The utility model discloses a kind of piston with returning quickly function, including piston top, piston body, sets on piston body
There is annular groove, matched rectangular seal is installed in annular groove, it is characterised in that: is equipped with a bullet in the piston body
Property ball；The elastic ball is all connected with a fixed link in four sides of front and back up and down；The piston body, which is equipped with, to match with fixed link
Through-hole；One end of the fixed link is located in through-hole, and the fixed link end is hinged with an elastic piece；The elastic piece is metal material
Matter, elastic piece one end are exposed to outside through-hole；The elastic ball is connected with a connecting rod, and connecting rod one end is connected with elastic string；The work
Cock body is equipped with a connecting hole to connect with annular groove；Described elastic string one end passes through connecting hole and is connected with rectangular seal
It connects.
The fixed link is equipped with a seal groove being mutually close to piston body inner wall；It is equipped in the seal groove and its phase
Matched O-ring.
The outer of the piston top is equipped with chamfering.
The beneficial effects of the utility model are:
Compared with prior art, it is pushed using the piston with returning quickly function of the utility model structure by hydraulic oil
Afterwards, the rectangular seal being installed in annular groove is squeezed, so that elastic deformation occurs, since rectangular seal passes through elasticity
Rope is connected with connecting rod, and connecting rod is then connected on elastic ball, therefore when elastic deformation occurs for rectangular seal, elastic string is same
Sample is pullled, and elastic string and elastic ball all can play the role of auxiliary to rectangular seal by the elasticity of itself, increases square
Elastic force when shape sealing ring resets, enables rectangular seal by the elastic force of enhancing rapidly by brake callipers piston return, no
Can there is a situation where brake callipers to drag brake, guarantee the traffic safety of driving personnel, and the elastic auxiliary energy of elastic string and elastic ball
The probability for reducing rectangular seal flexibility missing, extends the service life of rectangular seal.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the piston that the utility model has returning quickly function；
Fig. 2 is the enlarged drawing in the portion Figure 1A；
Fig. 3 is the right side view for the piston that the utility model has returning quickly function.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
It please referring to Fig.1 to Fig.3, the utility model provides a kind of piston with returning quickly function, including piston top 1,
Piston body 2, piston body 2 are equipped with annular groove 3, are equipped with matched rectangular seal 4, the piston in annular groove 3
An elastic ball 5 is equipped in body 2；About 5 front and back of elastic ball, four sides are all connected with a fixed link 6；The piston body 2 is equipped with
The through-hole 7 to match with fixed link 6；One end of the fixed link 6 is located in through-hole 7, and the end of fixed link 6 is hinged with an elastic piece
8；The elastic piece 8 is metal material, and 8 one end of elastic piece is exposed to outside through-hole 7；The elastic ball 5 is connected with a connecting rod 9, even
9 one end of bar is connected with elastic string 10；The piston body 2 is equipped with a connecting hole 11 to connect with annular groove 3；The elastic string
10 one end pass through connecting hole 11 and are connected with rectangular seal 4.
The fixed link 6 is equipped with a seal groove 12 being mutually close to 2 inner wall of piston body；It is equipped in the seal groove 12
Matched O-ring 13.
The outer of the piston top 1 is equipped with chamfering.
The application method of the utility model is as follows:
When automobile is slowed down or is braked, hydraulic oil can be poured rapidly in the caliper of brake callipers, push position
Piston is moved in the piston top 1 of the piston in brake callipers, as piston is pushed by hydraulic oil, is installed in annular groove
Rectangular seal 4 be squeezed, so that elastic deformation occur, since rectangular seal 4 is connected by elastic string 10 with connecting rod 9
It connects, and connecting rod 9 is then connected on elastic ball 5, therefore when elastic deformation occurs for rectangular seal 4, elastic string 10 is equally drawn
It pulls, and elastic string 10 and elastic ball 5 all can play the role of auxiliary to rectangular seal 4 by the elasticity of itself, increase rectangle
Elastic force when sealing ring 4 resets enables rectangular seal 4 by the elastic force of enhancing rapidly by brake callipers piston return, no
Can there is a situation where brake callipers to drag brake, guarantee the traffic safety of driving personnel, and elastic string 10 and the elasticity of elastic ball 5 assist
The probability of 4 flexibility missing of rectangular seal can be reduced, the service life of rectangular seal 4 is extended.
Since four sides of the front and back of elastic ball about 5 are all connected with fixed link 6, piston body 2 is equipped with to match with fixed link 6
One end of through-hole 7, fixed link 6 is located in through-hole 7, and the end of fixed link 6 is hinged with elastic piece 8, therefore outside piston is by hydraulic oil
When top, as rectangular seal 4 elastic deformation also occurs for elastic piece 8, after brake callipers slow down or brake, elastic piece
8 will pass through itself elasticity auxiliary rectangular seals 4 drive piston return, it follows that the utility model by elastic piece 8 with
Rectangular seal 4 drives piston return simultaneously, is equivalent to using two strands of elastic force and completes the return of piston, and piston can be at two strands
Rapid return under the action of elastic force, will not there is a situation where brake callipers to drag brake.
Rectangular seal 4 is since easily there is a situation where agings for itself rubber material, but elastic piece 8 is metal material, is not easy
There is a situation where agings, therefore even if rectangular seal 4 is followed the string due to aging, piston can also be completed by elastic piece 8
Return, will not there is a situation where brake callipers to drag brake.
Fixed link 6 is equipped with the seal groove 12 being mutually close to 2 inner wall of piston body, is equipped in seal groove 12 and matches with it
O-ring 13, the presence of O-ring 13 can guarantee that hydraulic oil will not be penetrated into piston by through-hole 7, will not influence hydraulic oil
Hydraulic pressure guarantees that piston can be stablized and quickly be ejected outward by hydraulic oil.
