Abstract
The utility model discloses a kind of parking self-regulated caliper, the purpose of this utility model is a kind of rational in infrastructure, parking self-regulated caliper that using effect is good of design.The technical solution of the utility model is, a kind of parking self-regulated caliper, it comprises caliper, return spring, driving cam is arranged on the top in caliper, and adjusting nut contacts with driving cam, on adjusting nut, be set with return spring, return spring bottom is provided with thrust-bearing, back-up ring is fixed thrust-bearing, and the screw rod on piston screws in adjusting nut, and the bottom of piston is provided with seal ring.The utility model is rational in infrastructure, and using effect is good, and processing technology is more reasonable, easy, and the utility model changes to involute cam by driving mechanism and drive, and can make resistance arm is a steady state value, thereby ensures that driving force is stable; Cancel return spring abutment, the nut of rotation is fixed in caliper hole, simplified structure makes reliability of structure of the present utility model greatly improve simultaneously.
Description
Technical field:
The utility model relates to the parking device that automobile is used, particularly a kind of parking self-regulated caliper using during for automobile parking.
Background technique:
Existing parking self-regulated caliper is by eccentric groove and push pedal drive screw, thereby promotes piston; While returning, under the promotion of return spring, adjusting screw rod return back to original position, because seal ring has been return resistance to piston, thereby make to produce pulling force between adjusting screw rod and the nut of internal piston, force nut to roll on smooth ball, thereby make to produce relative rotation between nut and screw rod, screw rod is screwed out from nut, ensure brake clearance, but the structure of existing parking self-regulated caliper, and it adopts eccentric groove and push pedal drive screw at drive part, making resistance arm is a variate, thereby causes driving force unstable; The return spring abutment of standing screw is complex-shaped, assembling difficulty, and after assembling, return spring abutment, because assembling is not in place or elasticity weakens, easily causes return spring abutment to come off, thus cause caliper parking to be lost efficacy, and therefore reliability is lower; And the nut of rotating part is assemblied in piston, and its structure is more complicated, and processing technology difficulty is larger.
Summary of the invention:
The purpose of this utility model is a kind of rational in infrastructure, parking self-regulated caliper that using effect is good of design.
The technical solution of the utility model is, a kind of parking self-regulated caliper, it comprises caliper, return spring, is characterized in that: driving cam is arranged on the top in caliper, and adjusting nut contacts with driving cam, on adjusting nut, be set with return spring, return spring bottom is provided with thrust-bearing, back-up ring is fixed thrust-bearing, and the screw rod on piston screws in adjusting nut, and the bottom of piston is provided with seal ring.
The utility model is rational in infrastructure, and using effect is good, and processing technology is more reasonable, easy, and the utility model changes to involute cam by driving mechanism and drive, and can make resistance arm is a steady state value, thereby ensures that driving force is stable; Cancel return spring abutment, the nut of rotation is fixed in caliper hole, simplified structure makes reliability of structure of the present utility model greatly improve simultaneously.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, specific embodiment of the utility model is, a kind of parking self-regulated caliper, and it comprises caliper 1, return spring 4, driving cam 2 is arranged on the top in caliper, and adjusting nut 3 contacts with driving cam, is set with return spring, return spring bottom is provided with thrust-bearing 5 on adjusting nut, back-up ring 6 is in thrust-bearing bottom, thrust-bearing is fixed, and the screw rod on piston screws in adjusting nut, and the bottom of piston is provided with seal ring 7.In use, vehicle is in the time of parking for the utility model, and driving cam drives adjusting nut, and the piston on nut lead-screw, stretches out piston, finally makes brake pad press-fit brake disc, thereby realizes parking.While unclamping parking, return spring makes adjusting nut return, thereby pull piston return, along with the increase of piston return amount, seal ring increases gradually to the return resistance of piston, in the time that the slip resistance between the screw rod on adjusting nut and piston is less than the return resistance of seal ring, piston stops return, force adjusting nut to slide on thrust-bearing, thereby the overhang of screw rod is increased, realize the self-regulated of brake clearance.
The utility model is rational in infrastructure, and using effect is good, and processing technology is more reasonable, easy, has improved the using effect of parking self-regulated caliper, has improved the quality of product of parking self-regulated caliper.
