Description
Technical field
The utility model belongs to hydraulic pressure of motor vehicle disk type braker technical field, particularly relates to a kind of clamp structure reducing car brakeing distance.
Background technique
In hydraulic pressure of motor vehicle disc brake field, most break uses single rectangular seal.When braking at every turn, piston produces mobile under the effect of hydraulic pressure, and piston can drive rectangular seal generation resiliently deformable simultaneously, when after clamping brake disc, piston stops mobile, and produce braking force, now brake fluid can make up whole piston displacement space and rectangular seal deformation space.After end of braking, rectangular seal drives piston return, and rectangular seal self-deformation recovers simultaneously.
Realizing in process of the present utility model, model utility people finds that prior art at least exists following problem: because rectangular seal during existing structure brake produces resiliently deformable, need liquid measure to have comparatively significantly to promote to clamp, and need liquid measure conference to affect pedal travel, thus affect stopping distance, so the shortcoming of prior art is under the prerequisite that piston return amount is certain, clamp need liquid measure larger.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of when piston return amount is constant, and reducing brake calipers needs liquid measure to reduce the clamp structure of car brakeing distance.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of clamp structure reducing car brakeing distance, comprise caliper and piston, described piston is slidably mounted in described caliper, and described piston contacts with friction plate and movable friction plate can be with to move thus clamp brake disc; Described caliper inwall is provided with the rectangular seal contacted with piston outer periphery, and described caliper inwall is provided with the seal ring be connected with piston seal near rectangular seal position; When piston driving friction plate clamping brake disc, car brakeing, described rectangular seal generation deformation and the spring-back force that produces are greater than the force of sliding friction between seal ring and piston.
Described seal ring is O type circle.
Described O type circle is positioned at the side of rectangular seal near piston cavity.
Distance between described O type circle and rectangular seal is 1-10mm.
Described O type circle and rectangular seal material are EPDM.
O type circle and be interference fit between piston and caliper inwall.
A technological scheme tool in technique scheme has the following advantages or beneficial effect, adopt the Double seal ring structure of rectangular seal and O type circle, when piston return amount is constant, reducing brake calipers needs liquid measure, brake petal priming stroke can be reduced, improve sensitivity.
Accompanying drawing explanation
The structural representation of the clamp structure of reduction car brakeing distance of Fig. 1 for providing in the utility model embodiment;
Fig. 2 is the partial enlarged drawing of the O type circle position of Fig. 1;
Mark in above-mentioned figure is: 1, piston, and 2, O type circle, 3, rectangular seal, 4, brake shoe, 5, friction plate, 6, caliper, 7, brake disc.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
See Fig. 1, a kind of clamp structure reducing car brakeing distance, comprises caliper 6 and piston 1, and piston 1 is slidably mounted in caliper 6, and piston 1 contacts with friction plate 5 and movable friction plate 5 can be with to move thus clamp brake disc 7; Caliper 6 inwall is provided with the rectangular seal 3 contacted with piston 1 periphery, and caliper 6 inwall is provided with the seal ring be tightly connected with piston 1 near rectangular seal 3 position; When piston 1 is with movable friction plate 5 to clamp brake disc 7, car brakeing, the spring-back force that rectangular seal 3 deformation occurs and produces is greater than the force of sliding friction between seal ring and piston 1, driven plunger 1 rollback under the effect of the spring-back force that piston 1 can be produced in rectangular seal 3 deformation.Seal ring is O type circle 2.
An O type circle 2 is added in clamp inside.Rectangular seal 3 plays return effect, and O type circle 2 plays seal action.When car brakeing, piston 1 produces mobile under the effect of hydraulic pressure, piston 1 can drive rectangular seal 3 that resiliently deformable occurs simultaneously, when after clamping brake disc 7, piston 1 stops mobile, produces braking force, isolates owing to there being O type circle 2, now brake fluid only fills up piston 1 displacement space, can not cause need liquid measure to increase because rectangular seal 3 is out of shape.After vehicle brake off, rectangular seal 3 drives piston 1 rollback, overcomes O type circle 2 sliding force simultaneously, and rectangular seal 3 self-deformation recovers.Brake calipers needs liquid measure little, can reduce brake petal priming stroke, and improve sensitivity, pedal travel is little, and stopping distance is short.Measure through overtesting, calculate when generally reaching 0.6g by car load retardation, pedal effective travel about can reduce 10%, reduces brake-pedal travel effect highly significant.
O type circle 2 is positioned at the side of rectangular seal 3 near piston cavity.
As shown in Figure 2, the distance between O type circle 2 and rectangular seal 3 is that the distance between L, O type circle 2 and rectangular seal 3 is shorter, is more conducive to the axial arranged of clamp; But distance is more short is more unfavorable for product self-strength and manufacturing, and through demonstration, distance is arranged on 1-10mm optimum, can balance both demands.
O type circle 2 and rectangular seal 3 material are EPDM.
O type circle 2 and be interference fit between piston 1 and caliper 6 inwall, realizes reliable sealing.
After adopting above-mentioned structure, adopt the Double seal ring structure of rectangular seal 3 and O type circle 2, when piston 1 return amount is constant, reducing brake calipers needs liquid measure, can reduce brake petal priming stroke, improves sensitivity.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
