Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brake calipers for a loader driving axle, in particular to an anti-loosening structure for fixing bolts of brake calipers for a loader driving axle. Background Art
[0002] The existing dry loader drive axle is generally composed of an axle housing, a main reducer assembly, a wheel reducer assembly, a half shaft and a brake caliper assembly, and the brake caliper is fixed to the brake caliper bracket of the axle housing by a hexagonal bolt. In actual use, the brake caliper fixing structure is prone to loosening of the hexagonal bolt due to frequent braking, which in turn causes the caliper body of the brake caliper assembly to break, shortening the product life and affecting safety. Summary of the invention
[0003] The utility model aims to solve the above defects and provide a loader drive axle brake caliper fixing bolt anti-loosening structure with simple structure, low manufacturing and maintenance costs, good brake caliper fixing bolt anti-loosening effect, long product service life, and safe and reliable operation.
[0004] To achieve the above purpose, the utility model loader drive axle brake caliper fixing bolt anti-loosening structure comprises a wheel side reducer assembly 1, a bridge housing 2, a brake caliper bracket 2-1, a hexagonal bolt 3, a brake caliper assembly 4, a double-hole stop washer 5 with a hole 5-1 and a limit block 5-2, the brake caliper assembly 4 is fixed to the brake caliper bracket 2-1 of the bridge housing 2 by the hexagonal bolt 3; the double-hole stop washer 5 is arranged at the fitting surface where the brake caliper assembly 4 is connected with the hexagonal bolt 3, according to the structural characteristics of the mounting hole of the brake caliper assembly 4, A single brake caliper assembly is provided with two double-hole stop washers 5, which are arranged in an eight-shaped shape. Each bolt hole of the double-hole stop washers 5 is provided with two protrusions with a larger inner end and a smaller outer end. The protrusions are bent to form limit blocks 5-2. A limit block 5-2 for each hole 5-1 of each double-hole stop washers 5 is located on the horizontal axis of the line connecting the two holes 5-1, and the other limit block 5-2 is at an angle of 60° to the horizontal axis, so that the hexagonal head of the hexagonal bolt 3 has two vertical surfaces restricted by the limit blocks 5-2 of the double-hole stop washers 5.
[0005] The above-mentioned anti-loosening structure of the brake caliper fixing bolt of the loader driving axle has the following technical characteristics and beneficial effects by adding an anti-rotation gasket at the brake caliper fixing bolt:
[0006] 1. By adding a double-hole stop washer at the fixing position of the hexagonal bolt, the hexagonal bolt is prevented from loosening, thereby preventing the brake caliper fixing bolt from loosening. The protrusion at each bolt hole of the double-hole stop washer is designed to be large at the inner end and small at the outer end, and is designed in two pieces, which further improves the anti-loosening effect and is easy to be bent into a limit block; 2. The structure is simple and compact, the production cost is low, the operation is safe and reliable, and the service life is long. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The specific embodiment of the anti-loosening structure of the brake caliper fixing bolt of the loader drive axle of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0012] Figure 1-Figure 3 As shown, the utility model loader drive axle brake caliper fixing bolt anti-loosening structure comprises a wheel side reducer assembly 1, a bridge housing 2, a brake caliper bracket 2-1, a hexagonal bolt 3, a brake caliper assembly 4, a double-hole stop washer 5 with a hole 5-1 and a limit block 5-2, the brake caliper assembly 4 is fixed to the brake caliper bracket 2-1 of the bridge housing 2 by the hexagonal bolt 3; the double-hole stop washer 5 is arranged at the fitting surface where the brake caliper assembly 4 is connected to the hexagonal bolt 3. According to the structural characteristics of the mounting hole of the brake caliper assembly 4, a single The brake caliper assembly is provided with two double-hole stop washers 5, which are arranged in an eight-shaped shape. Each bolt hole of the double-hole stop washers 5 is provided with two protrusions with a larger inner end and a smaller outer end. The protrusions are bent to form limit blocks 5-2. A limit block 5-2 for each hole 5-1 of each double-hole stop washers 5 is located on the horizontal axis of the line connecting the two holes 5-1, and the other limit block 5-2 is at an angle of 60° to the horizontal axis, so that the hexagonal head of the hexagonal head bolt 3 has two vertical surfaces restricted by the limit blocks 5-2 of the double-hole stop washers 5.
[0013] During installation, first insert the hexagonal bolt 3 into the hole 5-1 of the double-hole stop washer 5, and then fit the brake caliper assembly 4 onto the brake caliper bracket 2-1, with the bolt holes aligned; after screwing the hexagonal bolt 3 into the bolt hole of the brake caliper bracket 2-1 for 2 to 3 threads, use a pneumatic gun to lock the hexagonal bolt 3, and use a torque-fixing device to apply force to the hexagonal bolt 3. After completion, use a tool to bend the protrusion of the double-hole stop washer 5 into a limit block 5-2. After the limit block 5-2 is attached to the vertical surface of the hexagonal bolt 3, the assembly is completed.
