Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings of the specification.

Example 1:

as shown in fig. 1, the present embodiment relates to a split axle, which includes an axle main body 1; the middle of the axle main body 1 is provided with a differential assembly 2, two ends of the axle main body 1 are detachably connected with an axle shaft 3, and the end part of the axle shaft 3 is detachably connected with a brake disc 4. The utility model adopts the disc brake mode, which is favorable for heat dissipation, and changes the force transmission structure through the differential mechanism assembly 2, so that the transmission torque is increased, and the traction force of the tractor is improved; and a split structure is adopted, so that the device is convenient to maintain and replace independently, and the cost is saved.

One end of the axle shaft 3 is connected with the brake disc 4 through a flange, and the other end of the axle shaft extends into the axle main body 1 and is connected with the differential assembly 2.

The working principle is as follows: when the utility model is used, the brake is carried out by the disc brake mode of the brake disc 4, thus solving the problem that the drum brake is difficult to radiate heat; the differential assembly 2 is used for changing a force transmission structure, so that the transmission torque is increased, and the traction force of the tractor is improved; the brake disc 4, the axle shaft 3 and the axle main body 1 are connected by adopting a split structure, so that the single maintenance and replacement are convenient, the traction device is suitable for six-wheel drive, eight-wheel drive, ten-wheel drive and other traction locomotives, and has wide application range and large traction force.
