Embodiment Construction

[0022] as attached figure 1 And attached figure 2 Shown: The drive axle assembly is mainly composed of axle housing assembly 1, central disc brake assembly 2, wheel service brake assembly 3, wheel side reducer 4, wheel hub 5, half shaft bushing 6, half shaft 7, The differential gear 8, the final reducer housing 9, the final reducer 10 and its accessories are composed. The axle housing assembly 1 is cast integrally at one time.

[0023] Such as image 3 , Figure 4 central disc brake shown, and combined figure 1 , due to the limited space of the axle housing assembly, in order to double the brake execution force without changing the size of the brake cylinder, the present invention designs a clamp-type self-energizing mechanism. The principle of the pliers-type self-energizing mechanism is similar to a hand pliers, except that the jaws and the handle are on the same side of the fulcrum. When the brake is released, the external air pressure acts on the vacuum booster cyli...

Abstract

The invention relates to a driving axle assembly of a large-speed ratio mining vehicle, and provides a driving front axle of a large-speed ratio mining vehicle which comprises an axle case and a central brake. The driving front axle of the large-speed ratio mining vehicle is characterized in that the axle case is an integral-combination axle case; the central brake also comprises a pincers type force self-amplifying mechanism which comprises a vacuum boosting cylinder, a piston rod, a brake rocker and a rocker backing pin, wherein the vacuum boosting cylinder is fixedly connected to a support, the lower end of the brake rocker is installed on a brake pincers body through the rocking backing pin, the upper end of the brake rocker is connected with the piston rod of the vacuum boosting cylinder, and the middle of the brake rocker is provided with a bulge which can be in contact with a brake shoe. The invention has the characteristics of simple structure, large transmission speed ratio, low processing cost and wear resistance.

Description

technical field [0001] The invention relates to the field of vehicle drive axles, in particular to a drive axle assembly of a mine vehicle with a high speed ratio. Background technique [0002] Domestic integral axle housings are all integrally cast. Although the requirements for strength and rigidity are met, the process is complicated and the processing cost is too high. The existing pneumatic central brakes in China require a large braking force from the outside to brake, and require a large-sized vacuum booster as an auxiliary, and there are many supporting parts. In addition, the existing domestic spherical gaskets between the bevel gear of the differential and the differential housing are all made of a single material, which has a high probability of wear and poor effect. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a large-speed-ratio mining vehi...
