Fig. 1 is the schematic top plan view of the utility model one preferred embodiment;
Fig. 2 is the M-M generalized section of Fig. 1.
Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to shown in Fig. 1 to Fig. 2, the preferred embodiment of the integrated parking brake caliper of the utility model electric vehicle, comprises rear braking clamp body 1, rear mounting bracket 2, bonnet 3, swinging mounting 4, rear construction bolt 5, return spring 6, friction plate 7, taper spring 8, threaded guide rod 9, piston assembly 10, rectangular loop 11, steel ball 12 and steel ball sleeve 13.
Rear mounting bracket 2, bonnet 3 and swinging mounting 4 are coupled to each other respectively at rear braking clamp body 1, and bonnet 3 is fixedly connected with rear braking clamp body 1 by rear construction bolt 5.The friction plate 7 of brake use is fixed on rear mounting bracket 2.The cylinder hole that mutual perforation is set respectively in rear braking clamp body 1 and bonnet 3 inside, piston assembly 10, rectangular loop 11, taper spring 8, threaded guide rod 9, steel ball 12 and steel ball sleeve 13 are arranged in cylinder hole.Rectangular loop 11 is arranged on cylinder hole inwall and is socketed in the outer surface of piston assembly 10, and threaded guide rod 9 one end connect with piston assembly 10, and its other end connects with swinging mounting 4; On threaded guide rod 9, be provided with convex shoulder 14, taper spring 8, steel ball 12 and steel ball sleeve 13 are socketed on threaded guide rod 9, and be positioned at the cylinder body of bonnet 3, steel ball 12 and steel ball sleeve 13 are positioned at convex shoulder 14 near rear braking clamp body 1 side, and taper spring 8 is positioned at the opposite side of convex shoulder 14.Swinging mounting 4 is positioned at the outer end of bonnet 3; On swinging mounting 4, be provided with return spring 6, the other end of return spring 6 is arranged on bonnet 3.
The utility model adopts taper spring 8, steel ball 12 and steel ball sleeve 13 is placed in bonnet 3, thereby makes the use amount of saving component simple in structure, and better avoids the inefficacy causing because of component.Swinging mounting 4 is fixed on threaded guide rod 9, apply power rear thread guide rod 9 to swinging mounting 4 and rotate and pull return spring 6, threaded guide rod 9 drives steel ball 12 move and compress taper spring 8 along the track in steel ball sleeve 13, when threaded guide rod 9 move on and elimination and piston assembly 10 in gap after, promote again piston assembly 10 and move toward friction plate 7, and cause rectangular loop 11 to be out of shape.After piston assembly 10 contacts with friction plate 7, promotion friction plate 7 clamps brake disc and reaches parking braking effect.When eliminating after the power of swinging mounting 4, return spring 6, taper spring 8 and rectangular loop 11 drive piston assembly 10, steel ball 12 and swinging mounting 6 to get back to home position, eliminate parking braking power.
