Description
Technical field
The invention belongs to hydraulic pressure of motor vehicle disk brake technical field, more particularly to a kind of vehicle braking distance that reduces
Clamp structure.
Background technology
In hydraulic pressure of motor vehicle disc brake field, most brakes use single rectangular seal.
Every time during braking, piston produces movement in the presence of hydraulic pressure, while piston can drive rectangular seal to occur elastic deformation, when
Clamp after brake disc, piston stops movement, produce brake force, now brake fluid can make up whole piston displacement space and rectangle is close
Seal deformation space.After end of braking, rectangular seal drives piston return, while rectangular seal self-deformation recovers.
During the present invention is realized, inventor has found that prior art at least has problems with：Due to existing structure
Rectangular seal produces elastic deformation during brake, and clamp are needed liquid measure to have more to be obviously improved, and needs liquid measure big
Pedal travel can be influenceed, so that braking distance is influenceed, so the shortcoming of prior art is on the premise of piston return amount is certain,
Clamp need liquid measure larger.
The content of the invention
The technical problems to be solved by the invention are to provide one kind in the case where piston return amount is constant, reduce caliper
Liquid measure is needed to reduce the clamp structure of vehicle braking distance.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of reduction vehicle braking distance
Clamp structure, including caliper and piston, the piston are slidably mounted in the caliper, and the piston is contacted and energy with friction plate
Band movable friction plate motion is so as to clamping brake disc；The caliper inwall is provided with the rectangular seal contacted with piston outer periphery, described
Caliper inwall is provided with the sealing ring being connected with piston seal close to rectangular seal position；When piston driving friction plate clamping braking
When disk, vehicle braking, the screen resilience that the rectangular seal is deformed upon and produced is more than the slip between sealing ring and piston
Frictional force.
The sealing ring is O-ring.
The O-ring is located at rectangular seal close to the side of plunger shaft.
The distance between the O-ring and rectangular seal are 1-10mm.
The O-ring is EPDM with rectangular seal material.
It is interference fit between O-ring and piston and caliper inwall.
A technical scheme in above-mentioned technical proposal has the following advantages that or beneficial effect, using rectangular seal and O
The Double seal ring structure of type circle, in the case where piston return amount is constant, reduction caliper needs liquid measure, can reduce brake pedal
Priming stroke, improves sensitivity.
Brief description of the drawings
Fig. 1 is the structural representation of the clamp structure for reducing vehicle braking distance provided in the embodiment of the present invention；
Fig. 2 is the partial enlarged drawing of Fig. 1 O-ring position；
Mark in above-mentioned figure is：1st, piston, 2, O-ring, 3, rectangular seal, 4, Brake pad, 5, friction plate, 6,
Caliper, 7, brake disc.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1, a kind of clamp structure of reduction vehicle braking distance, including caliper 6 and piston 1, piston 1 are slidably installed
In caliper 6, piston 1 contacts with friction plate 5 and can be with the motion of movable friction plate 5 so as to clamping brake disc 7；The inwall of caliper 6 is provided with
The rectangular seal 3 contacted with the periphery of piston 1, the inwall of caliper 6 is provided with close to the position of rectangular seal 3 and is tightly connected with piston 1
Sealing ring；When piston 1 is with the clamping brake disc 7 of movable friction plate 5, vehicle braking, rectangular seal 3 is deformed upon and produced
Screen resilience is more than the force of sliding friction between sealing ring and piston 1, piston 1 is produced in the deformation of rectangular seal 3
Piston 1 is driven to retract in the presence of screen resilience.Sealing ring is O-ring 2.
An O-ring 2 is added inside clamp.Rectangular seal 3 plays return effect, and O-ring 2 plays sealing and made
With.When vehicle is braked, piston 1 produces movement in the presence of hydraulic pressure, while piston 1 can drive rectangular seal 3 to occur bullet
Property deformation, when clamp brake disc 7 after, piston 1 stop movement, produce brake force, due to there is O-ring 2 to isolate, now brake fluid only
The displacement space of piston 1 is filled up, will not cause because rectangular seal 3 is deformed and need liquid measure to increase.Vehicle is released after braking, and rectangle is close
Seal 3 retracts with piston 1, while overcoming the sliding force of O-ring 2, the self-deformation of rectangular seal 3 recovers.Caliper needs liquid measure
It is small, brake pedal priming stroke can be reduced, sensitivity is improved, pedal travel is small, and braking distance is short.Surveyed through overtesting
Amount, is calculated when typically reaching 0.6g by vehicle deceleration, and pedal effective travel can about reduce 10%, reduces brake-pedal travel effect
Fruit highly significant.
O-ring 2 is located at rectangular seal 3 close to the side of plunger shaft.
As shown in Fig. 2 the distance between O-ring 2 and rectangular seal 3 are L, between O-ring 2 and rectangular seal 3
Distance is shorter, is more conducive to the axial arranged of clamp；But apart from more short more be unfavorable for product self-strength and processing and manufacturing, pass through
Demonstration, it is optimal that distance is arranged on 1-10mm, can balance both demands.
O-ring 2 is EPDM with the material of rectangular seal 3.
It is interference fit between O-ring 2 and piston 1 and the inwall of caliper 6, realizes reliable sealing.
After above-mentioned structure, using the Double seal ring structure of rectangular seal 3 and O-ring 2, in the return amount of piston 1
In the case of constant, reduction caliper needs liquid measure, can reduce brake pedal priming stroke, improves sensitivity.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
