[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Please see Figures 1 to 4This utility model provides a technical solution: an ultra-short brake half-shaft, including an axle assembly 1 and an axle mounting flange 8. The axle assembly 1 is mounted inside the axle mounting flange 8. Mounting bolts 4 inside the brake chamber bracket mounting plate 2 and the detachable brake chamber bracket 3 are located near the four corners of the brake chamber bracket mounting plate 2. The mounting bolts 4 provide a stable connection between the brake chamber bracket mounting plate 2 and the detachable brake chamber bracket 3, enabling quick disassembly of the brake chamber bracket mounting plate 2 and the detachable brake chamber bracket 3, facilitating disassembly and assembly during subsequent maintenance and improving equipment usability. Simultaneously, the four mounting bolts 4 stably fix the axle assembly 1 and the brake chamber bracket mounting plate 2. The brake chamber bracket mounting plate 2 is welded to the outside of the axle assembly 1, and the detachable brake chamber bracket 3 is provided on the outside of the brake chamber bracket mounting plate 2. The top surface of the spring washer 5 is in contact with the bottom surface of the brake chamber bracket mounting plate 2, and the detachable brake chamber bracket 3... The vertical cross-section is an obtuse triangle. The axle assembly 1 is first installed with the axle mounting flange 8. The brake chamber bracket mounting plate 2 is installed on the outside of the axle assembly 1. The detachable brake chamber bracket 3 and brake chamber 7 are fixed with bolts. Then, the spring washer 5 is placed between the mounting nut 6 and the brake chamber bracket mounting plate 2. The mounting bolt 4 is inserted from above and downwards from the detachable brake chamber bracket 3. The mounting bolt 4, the spring washer 5 and the mounting nut 6 are used to stably fix the brake chamber bracket mounting plate 2 and the detachable brake chamber bracket 3. Then, the brake adjusting arm 9 and the brake chamber 7 are installed. The brake chamber bracket mounting plate 2 and the detachable brake chamber bracket 3 are internally fitted with four mounting bolts 4.
