Problems solved by technology
The welded structure leads to the axle and axle terminal must be a one-piece structure, which limits the modular design
If the axle and the axle terminal are changed to an assembly structure, the problem of the installation space of the brake and the space for the oil pipe cannot be solved
[0005] The current installation structure of the terminal brake, the installation position of the brake disc to the hub assembly is not reasonable enough, the braking heat is easily transferred to the bearing and oil seal, resulting in overheating failure

Embodiment Construction
[0024] The present invention will be further described below according to the accompanying drawings and embodiments.
[0025] Such as Figure 1 to Figure 5 Described, a kind of vehicle axle terminal brake installation structure of mine dump truck, comprises axle housing 1, half shaft bushing 2, brake disc 4, terminal brake 10, bracket 11 and wheel hub assembly 6; Said bracket 11 is semi-circular structure, the terminal brake 10 is connected to the bracket 11 through the first hexagon socket bolt 12 and the second hexagon socket bolt 13, such as image 3 As shown, the index circle diameter of the second hexagon socket bolt 13 is greater than the index circle diameter of the first hexagon socket bolt 12 (that is, the second hexagon socket bolt 13 is located on the bracket 11 outside the first hexagon socket bolt 12). The bracket 11 is provided with a counterbore for accommodating the head of the hexagon socket bolt 12, and the socket bolt 12 will not interfere when the bracket ...

The invention belongs to the technical field of mining dump trucks, and in particular relates to an installation structure and installation method of an axle terminal brake of a mining dump truck, including an axle housing, a half shaft bushing, a brake disc, a terminal brake, a bracket and a hub assembly The bracket is a semi-circular structure, the terminal brake is movably connected to the bracket, the axle housing, the axle sleeve and the bracket are movably connected as a whole, and the axle housing is also connected to the frame of the mining dump truck; The brake disc is set on the half shaft sleeve, and the brake disc is movably connected with the hub assembly, the hub assembly is connected with the tire rim of the mining dump truck, and the brake disc is connected with the hub assembly There is an adjusting spacer between them. The application solves the installation problem of the assembled axle terminal. The structure is simple and reliable. The structure of the brake disc clearance is adjusted through the adjustment gasket of the improved structure. The installation and adjustment process is simple and does not depend on the experience of personnel.
Description
technical field [0001] The invention belongs to the technical field of mining dump trucks, and in particular relates to an installation structure and installation method of an axle terminal brake of a mining dump truck. Background technique [0002] The axle of the mining dump truck is the load-carrying and driving functional device of the vehicle, and the terminal drive is a part of the axle, which is used to install tires, transmit the driving torque from the transmission system, and has a reliable braking function, so that the vehicle has the ability to stop And the function of controlling the speed of the ramp. [0003] Dry disc brakes are commonly used brake components for axle terminals, and have the characteristics of simple structure and stable and reliable braking performance. The installation and use of the terminal brake of the current axle terminal mainly has the following problems: [0004] Since the installation space of the terminal brake is inside the rim a...
