As shown in Figure 8, the second boss 111 is provided with the second end face 113, second end face 113 and the first end face 131 to being oppositely arranged.Second end face 113 is provided with direction recess, is the second direction recess.As shown in Figure 8, second end face 113 is circumferentially evenly provided with three the second direction recess 116, second direction recess 116 identical with the structure of the first direction recess 131, three the second direction recess 116 on three the first direction recess 132 and the second end face, be oppositely arranged, one_to_one corresponding.
Convex surface of the present invention is provided by the ball on ball bearing 12, ball bearing 12 is arranged between the first end face 131 and the second end face 113, have three balls, be separately positioned between three the first direction recess 132 and the sphere of three the second direction recess 116, to contact with the second direction recess with the first direction recess 132 and connect, the radius of ball and the radius r matching size of sphere close.
As shown in Figure 2, rob support 22 is bolted on caliper 100, and parking pull bar 6, when under tension occurrence positions moves, is subject to the spacing of rob support 22.One end of pull bar return spring 23 is connected with driving pull bar 6, and one end is connected with rob support 22, when parking braking is cancelled, parking pull bar 6 depart from rob support 22 spacing after, in the effect of pull bar return spring 23 elastic deformation force, can mounting point be returned to.
Integral type brake caliper of the present invention, when service brake, brake fluid in braking line is inputted by oil inlet hole 101, promotes piston 5 by hydraulic coupling, and then promotes inner attrition piece 4, be adjacent to brake disc (not shown), caliper 100 is subject to the reaction force of hydraulic coupling, and the opposite direction of moving to piston 5 moves, and then promotion outside friction disc is adjacent to brake disc, thus clamping brake disc, realize service brake.After hydraulic coupling is removed, rectangular seal 24 pulls piston 5 to reset, and removes service brake.
As shown in Figure 9, when vehicle needs to stay dynamic braking, driver is after parking pull bar 6 force of integral type brake caliper of the present invention, and parking pull bar 6 rotates along piston 5 axis, and is subject to lasting pulling force, keeps parked state.Drive shaft 11 rotates under the drive of parking pull bar 6.Due to the position-limiting action of the spacing block set 133 of thrust axle sleeve 13, thrust axle sleeve 13 can not rotate with drive shaft 11, the second direction recess 116 that ball on ball bearing 12 is subject on the second end face 113 rotates the tangential force produced, roll along the first direction recess 132 and the second direction recess 116, because ball diameter remains constant, and the degree of depth of the first direction recess 132 and the second direction recess 116 diminishes gradually, first direction recess 132 must be subject to the extruding force of ball axis, thus make thrust axle sleeve 13, thrust axis 19 and piston 5 move axially, piston 5 promotes inner attrition piece 4 and to fit brake disc (not shown), caliper 100 is subject to the reaction force of parking thrust, the opposite direction of moving to piston 5 moves, and then promotion outside friction disc 3 is adjacent to brake disc (not shown), thus clamping brake disc, realize parking braking.During parking braking, first Compress Spring 14 one end is by the stop being subject to position-limited rack 16, and the other end is subject to the extruding of the first boss 134, can produce elastic deformation force; When parking pull bar 6 departs from the spacing of rob support, when removing parked state, end thrust disappears, piston 5 return under the effect of rectangular seal 24, brake off dish clamped condition; Thrust axle sleeve 13 moves to parking pull bar direction under the effect of the first Compress Spring 14, drives the ball on ball bearing 12 to keep in the center.
When inner attrition piece 4, outside friction disc 3 may wear to a certain degree, after lower thickness, piston 5 automatically moves forward under the effect of hydraulic action, compensate inside and outside friction plate thinning after the gap of generation.Now piston 5 departs from the abutting contact of thrust axis, and can gap be produced between thrust axis, because volute spring 17 remains compressive state, and the screw thread between thrust axis 19 and thrust axle sleeve 13 is for being in transmission connection, not locked, thrust axis 19 under spring force, rotates and moves to piston 5 moving direction, and the gap between piston 5 and thrust axis 19 is eliminated because of the effect of spring force.
Of the present inventionly only direction recess can be set on the first end face 131, convex surface be set on the second end face 113 simultaneously; Or direction recess is set on the second end face 113, the first end face 131 establishes convex surface, when can be implemented in parking braking equally, will the function moved axially be changed into.
Embodiment in the present invention, only for the present invention will be described, does not form the restriction to right, other equivalent in fact substituting, all in scope that those skilled in that art can expect.
