Embodiment
The below contrasts accompanying drawing, and the description by to embodiment is described in further detail the specific embodiment of the present invention, to help those skilled in the art inventive concept of the present invention, technological scheme is had more complete, accurate and deep understanding.
The of the present invention structure expressed such as Fig. 3, Fig. 4 for a kind of engineering machinery Zipper-type Parking Brake, comprises pivoted arm 7, and described break is installed in the bridge end of vehicle axle.The Zipper-type disk parking brake is connected to vehicle bridge end by mounting nuts 6.Flexible axle zip one end is connected with pivoted arm, and the other end is connected with brake handle.
What the present invention related generally to is the engineering machinery Zipper-type disk parking brakes such as loader, road roller.
In order to solve the problem that prior art exists and to overcome its defective, the goal of the invention that realizes improving the usefulness of break and reduce its installing space, the technological scheme that the present invention takes is:
As shown in Figure 3, Figure 4, engineering machinery Zipper-type Parking Brake provided by the present invention, described vehicle bridge is equipped with Moving plate 12, and described break is provided with the first caliper 1 and second caliper 5 of parallel distribution, and described the first caliper 1 and the second caliper 5 all are sleeved on the construction bolt 3; In these two calipers, be provided with the first friction plate assembly 10 and the second friction plate assembly 11, these two friction plate assemblies are clipped in described brake disc 12 between it; Pass described the first caliper 1 and the second caliper 5 with turnbuckle 9; End at described turnbuckle 9 connects running shaft, and at this end of turnbuckle 9 ball bearing mechanism 8 is installed, described ball bearing mechanism 8 is established the baffle plate of two annulars, be equipped with ball grooves on the opposing side of two ring baffles, be provided with ball in described ball grooves, the groove depth of described ball grooves forms variation from shallow to deep.
