Abstract
The utility model discloses a zero drags hydraulic braking calliper, including setting up at the epaxial brake caliper of wheel, install the piston in the brake caliper pneumatic cylinder, the open ring cavity has been offered on keeping away from the terminal surface of friction disc to the piston, has offered the annular on lieing in the piston outer peripheral face of open ring cavity, is provided with the spring steel band in the annular, and the width of spring steel band is lighter than the width of annular, and the both ends of spring steel band incurve from the opening part of open ring cavity respectively to extend to in the open ring cavity, lie in and has offered a slide opening and a screw on the flexion spring steel area of open ring cavity respectively, adjusting bolt's tip slide pass the slide opening and with screw looks spiro union, linked firmly the adjusting wheel on adjusting bolt. The utility model discloses the advantage lies in eliminating current brake caliper and has the defect that drags, reaches to reduce fuel consumption, extension friction disc life purpose.
Description
Technical field
The utility model relates to brake device for car, especially relates to zero and drags hydraulic braking clamp.
Background technique
During car brakeing, brake caliper working procedure is: driver steps on brake petal, make braking overall pump smaller volume and the brake fluid extruded, the oilhole of brake fluid by the road on self-retention clamp enters left chamber and promotes piston and move to right, also there is deformation in the rectangular seal closely matched with piston thereupon, eliminate the setting gap between friction plate and brake disc, and then tightly clamp and make wheel stall with the brake disc of wheel coaxial rotating and realize car brakeing.During brake release, braking overall pump volume recovers, and the deformation release of brake caliper seal ring promotes piston and moves to left, and brake fluid is back in braking overall pump, and friction plate is removed and returned to original setting gap to the clamping of brake disc.
But, by the many factors such as distortion and vehicle life cycle of accuracy of manufacturing, brake caliper rectangular seal, piston reset stroke after brake release is also inconsistent, the setting gap of friction plate and brake disc all reliably can not return to setting value at every turn, travel under this state just causing vehicle to depart from not exclusively (clamp residual) at friction plate and brake disc, drag (be commonly called as and dawdle) occur and cause fuel consume to increase, also shorten the working life of friction plate simultaneously.
Summary of the invention
The utility model object is to provide a kind of zero to drag hydraulic braking clamp.
For achieving the above object, the utility model takes following technical proposals:
Described in the utility model zero drags hydraulic braking clamp, comprises the brake caliper be arranged on wheel shaft, is installed on the piston in described brake caliper oil hydraulic cylinder; Described piston offers open annular cavity away from the end face of friction plate, the piston outer periphery face being positioned at described open annular cavity offers annular groove, Spring Steel Band is provided with in described annular groove, the width of described Spring Steel Band is less than the width of annular groove, the two ends of Spring Steel Band curve inwardly from the opening of open annular cavity respectively, and extend in open annular cavity; The curved part Spring Steel Band being positioned at open annular cavity offers a slide opening and a screw respectively, the end of adjustment bolt slide through described slide opening and with described screw bolt, described adjustment bolt is fixed with regulating wheel.
Described Spring Steel Band is provided with shell fragment away from the side of friction plate stretches out.
Described regulating wheel is ratchet.
The utility model advantage is that eliminating existing brake caliper exists the defect dragged, and reaches and reduces fuel consume, prolongation friction plate object in working life.

Fig. 3 is the left TV structure schematic diagram of Fig. 2.
Fig. 4 is the structural representation of Spring Steel Band described in the utility model.
Embodiment
As Figure 1-4, described in the utility model zero drags hydraulic braking clamp, comprises the brake caliper 1 be arranged on wheel shaft, is installed on the piston 2 in described brake caliper 1 oil hydraulic cylinder; The end face of described piston 2 away from friction plate 3 offers open annular cavity 4, piston 2 outer circumferential face being positioned at described open annular cavity 4 offers annular groove 5, Spring Steel Band 6 is provided with in described annular groove 5, the width of described Spring Steel Band 6 is less than the width of annular groove 5, the side of Spring Steel Band 6 away from friction plate 3 stretches out and is provided with multiple shell fragment 7, described shell fragment 7 is structure as a whole with Spring Steel Band 6, the two ends of Spring Steel Band 6 curve inwardly from the opening 8 of open annular cavity 4 respectively, and extend in open annular cavity 4; The curved part Spring Steel Band 6 being positioned at open annular cavity 4 offers a slide opening and a screw respectively, the end of adjustment bolt 9 slide through described slide opening and with described screw bolt, described adjustment bolt 9 is fixed with adjustment ratchet 10.
Utility model works principle is summarized as follows:
During car brakeing, the brake fluid of the braking overall pump oilhole 11 by the road on self-retention clamp 1 enters left chamber and promotes piston 2 and move to right, because Spring Steel Band 6 tensioner is in the cylinder wall of brake caliper 1, the attachment damping formed is greater than the elastic force of shell fragment 7, therefore shell fragment 7 by compression and energy storage be transferred to after on the right side of annular groove 5 to setting gap width (i.e. the width of Spring Steel Band 6 and the difference of annular groove 5 width), Spring Steel Band 6 and piston 2 start synchronizing moving, promote the brake disc 12 that friction plate 3 tightly clamps rotation, until realize braking completely.
During brake release, braking overall pump volume recovers, the deformation power of brake caliper 1 seal ring 13 and the elastic force synchronous release of shell fragment 7, continue to move to left after promoting the clamping that piston 2 moves to left, friction plate 3 is removed brake disc 12, until reach setting gap width (i.e. the width of Spring Steel Band 6 and the difference of annular groove 5 width).
Adjustment bolt 9 is fixed with adjustment ratchet 10, by rotating adjustment ratchet 10 different rotation direction, Spring Steel Band 6 can be made to tighten bottom annular groove 5 or tensioner in the cylinder wall of brake caliper 1.
