Description

Technical Field

[0001] The utility model relates to the technical field of excavator loader axles, in particular to a novel excavator loader axle. Background Art

[0002] The axle of an excavator loader refers to a special engineering machinery used for excavating, loading and transporting large materials such as earth, stone, coal, etc. The axle is an important part of its mechanical structure. Generally speaking, an excavator loader has at least two axles, namely the front axle and the rear axle. The main structural components of the axle include wheel hubs, gears, bearings, main reducers, etc. Its main function is to transmit power and bear loads, and it plays an important role in the operation of the machinery.

[0003] The axle needs to support the up and down shaking of the backhoe loader during its driving process. When the road is bumpy, the suspension of the body can buffer most of the impact, but the axle itself also has to bear part of the impact. However, in actual application, it is found that the existing shock-absorbing structure has poor shock-absorbing effect. Therefore, we propose a new type of backhoe loader axle. Utility Model Content

A reinforcing nut is threadedly connected to the reinforcing bolt, and the reinforcing nut abuts against the inner side of the inverted U-shaped gasket.

[0014] As an improved technical solution, the buffer leaf spring includes an upper leaf spring, which is movably connected to the fixed structure, a middle leaf spring is provided at the bottom of the upper leaf spring, and a lower leaf spring is provided at the bottom of the middle leaf spring. The outer surfaces of the upper leaf spring and the middle leaf spring are buckled with leaf spring buckles, and the lower leaf spring is movably connected to an inverted U-shaped gasket. The upper leaf spring, the middle leaf spring and the lower leaf spring are all provided with through holes for the reinforcing bolts to pass through.

[0015] As an improved technical solution, the lengths of the upper leaf spring, the middle leaf spring and the lower leaf spring gradually shorten, and all have a structure that is low in the middle and raised at both ends.

[0016] As an improved technical solution, both raised ends of the upper leaf spring are curled to form a cylindrical shape.

[0020] After adopting the above technical solution, the beneficial effects of the utility model are:

[0021] 1. When the backhoe loader encounters bumps while driving on the road, the suspension on the backhoe loader buffers most of the impact force, and the impact force of the axle-bearing part is absorbed by the buffer leaf spring composed of the upper leaf spring, the middle leaf spring and the lower leaf spring through elastic deformation to achieve buffering and shock absorption, thereby facilitating the buffering of the vertical downward impact force, and the buffering and shock absorption effect is good.
