Description
Technical Field
The invention relates to a mining vehicle axle housing, and belongs to the technical field of manufacturing of mining dump trucks.
Background
The mining dump truck has the characteristics of large bearing capacity, short transportation distance and high transportation efficiency. Because the road-mounted hydraulic system is often operated in mining areas or construction sites for engineering construction, road conditions are poor, and overload is serious. While the axle acts as a critical load bearing member, the impact of the sprung mass is all that is required to be borne by the axle.
At present, mining dump trucks running in mining areas in China can be divided into 4 multiplied by 2 and 6 multiplied by 4 structures according to driving modes, the 4 multiplied by 2 structures are basically electric transmission and mechanical transmission mining trucks, A-shaped frames and transverse stabilizer bars are arranged on a rear axle, and the axle is often designed to be very firm and heavy. Most of 6×4 structures are off-highway mechanical transmission wide dump trucks, and the axles of the dump trucks are matched with the steel plate springs and the thrust rods to be used, so that the steel plate spring seats are often broken due to stress concentration and the like.

The technical scheme is as follows: in order to solve the technical problems, the invention adopts the following technical scheme:
a mining vehicle axle housing comprising: the upper surfaces of two ends of the axle housing are cast with oil cylinder brackets; the upper wing surface and the lower wing surface on two sides of the axle housing are provided with longitudinal pull rod supports; a tie rod support is arranged on one side of the top surface of the axle housing; the center of the top surface of the axle housing is cast with a pipe clamp support; four supports are cast on the front side surface and the rear side surface of the axle housing respectively; the axle shell is provided with an arc-shaped axle bag, the axle bag is symmetrical about the horizontal central line of the axle, and a space is arranged between the vertical central line of the axle bag and the vertical central line of the axle.
Preferably, the cross-sectional shape of both ends of the axle housing is rectangular or circular.
As a preferable scheme, a boss is arranged on the oil cylinder support, and two threaded holes are arranged on the boss left and right; the two oil cylinder supports are bilaterally symmetrical relative to the vertical center line of the axle.
As an optimal scheme, grooves for installing snap springs and end faces for fixing bearings are machined on the longitudinal pull rod support, and the two groups of longitudinal pull rod support are bilaterally symmetrical relative to the vertical center line of the axle.
As a preferable scheme, the connecting lines of the centers of the holes of the oil cylinder support and the longitudinal pull rod support are on the same vertical plane, and an included angle alpha is formed between the connecting lines and the vertical plane of the center of the axle.
Preferably, the included angle alpha is set to be 2-5 degrees.
Preferably, two threaded holes are arranged on the pipe clamp support left and right,
preferably, the support is provided with two threaded holes vertically, and the support on the front side and the rear side of the axle housing is symmetrical relative to the vertical center line of the axle.
The beneficial effects are that: the axle housing of the mining vehicle axle provided by the invention can be applied to a rear axle assembly in a mining vehicle, and an oil cylinder support, a longitudinal pull rod support and a transverse pull rod support cast on the axle housing can form a novel suspension structure with corresponding parts. Compared with an axle housing provided with a leaf spring, the invention has the advantages of simple structure and light weight.
