Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described.
nullAs shown in Figure 1，The automobile belt parking brake self-regulated caliper of the present embodiment，Including caliper 1、On、Lower friction plate 21、22、Brake block 3 and self-regulated screw rod 4，Offer in caliper 1、Lower chamber 101、102，Self-regulated screw rod 4 is through、Lower chamber 101、In 102，And self-regulated screw rod 4 upper end connecting stay wire 5，Ball dish is set in upper cavity 101，Ball dish includes、Lower ball dish 61、62 and spin 63，On、Lower ball dish 61、Three grooves are all offered on 62，Coordinate is upper、Lower ball dish 61、Three spin 63 are set between 62，On the upside of upper ball dish 61, locating dowel 64 is set，Described locating dowel coordinate be inserted in upper cavity 101 in offer location hole 103，Lower ball dish 62 is fixed on self-regulated screw rod 4 on the ball dish platform 41 arranged，Below ball dish platform 41, disc spring 7 is set，Disc spring 7 upper end arranges packing ring，First plane bearing 8 is set between packing ring and ball dish platform 41，Piston 9 is set in lower chamber 102，Self-regulated nut 10 is set in piston 9，Self-regulated nut 10 is threadeded with self-regulated screw rod 4 lower end，Second plane bearing 11 is set on self-regulated nut 10，It is also provided with packing ring on second plane bearing 11，Spring 12 is set on packing ring，The other end of spring 12 withstands on the back-up ring 91 arranged on piston 9，Piston 9 lower end contacts with upper friction plate 21，Lower friction plate 22 is fixed on caliper 1，Brake block 3 is arranged on、Lower friction plate 21、Between 22，Upper cavity 101 upper end is provided with dust plug 13，Between piston 9 and caliper 1, sealing ring is set，It is also provided with sealing ring between self-regulated screw rod 4 and caliper 1.
nullWhen described automobile belt parking brake self-regulated caliper uses，When abrasion occurs in friction plate，Distance between friction plate and brake block 3 increases，Now the elastic force of spring 12 is applied on self-regulated nut 10，Due to threaded between self-regulated screw rod 4 and self-regulated nut 10，And it is the most locked，Self-regulated nut 10 screws out downwards a segment distance under elastic force effect，Self-regulated nut 10 drives outside sheathed piston 9 to move downwardly together again，Drive upper friction plate 21 downwards near brake block 3 by piston 9，Realization is automatically adjusted，Keep frictional force constant，Ensure that the brake force of caliper is stable，When parking of automobile，Self-regulated screw rod 4 is pulled to turn an angle by bracing wire 5，Self-regulated screw rod 4 drives lower ball dish 62 to rotate，Spin 63 is made to roll out in groove，On、Lower ball dish 61、Distance between 62 increases，Owing to upper ball dish 61 is fixed，Following ball dish 62 drives self-regulated screw rod 4 to move downward one end distance，Self-regulated screw rod 4 drives piston 9 to move downward again，Piston 9 acts on upper friction plate 21，Make、Lower friction plate 21、22 hold brake block 4 tightly，Fix brake block 4，Fix wheel，Realize parking brake function.
