Description

Mining front axle knuckle assembly

Technical Field

The utility model relates to a mining car axle technical field, specifically say a mining front axle knuckle assembly.

Background

The steering knuckle is one of main parts on an automobile steering axle, can enable an automobile to stably run and sensitively transfer the running direction, and has the functions of bearing the front load of the automobile, supporting and driving a front wheel to rotate around a main pin so as to steer the automobile. Currently there are two main structures: conventional enclosed structures and tiled structures.

The traditional closed structure, namely the steering knuckle notch part is a solid body, and the existing problems are that: 1. the main pin must be a disconnected upper main pin and a disconnected lower main pin, the coaxiality of the upper main pin and the lower main pin is not guaranteed well, and the steering is not light; 2. the upper and lower bushings are made of tin bronze, so that the weight is heavy and the cost is high; 3. the main pin is difficult to disassemble during later maintenance, liquid nitrogen is generally adopted for cold assembly in factories, and liquid nitrogen is absent in general places during actual use, so that the maintenance is inconvenient;

the structure of the tile cover, namely the gap part of the steering knuckle, is continuously enlarged, the semicircular tile cover is simultaneously added, the tile cover is fixed with the steering knuckle by two bolts, and the problem of the structure is as follows: 1. although the main pin can adopt an integral structure, in order to ensure the processing precision, the steering knuckle and the tile cover are integrally processed after being assembled, the tile cover needs to be disassembled when the axle assembly is assembled, and the tile cover is assembled after the main pin is assembled, so that the product precision is not well ensured, and the process is complex; 2. and the tile cover is added, so that the product is heavy.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the shortcomings existing in the prior art, and providing a front axle steering knuckle assembly for mining.

The utility model provides a technical scheme is: a mining front axle steering knuckle assembly comprises a steering knuckle, an upper main pin boss and a lower main pin boss, and is characterized in that the upper part and the lower part of the steering knuckle are respectively provided with an open notch structure, an installation plane and a threaded hole, the upper installation plane of the steering knuckle is connected with the upper main pin boss, and the lower installation plane of the steering knuckle is connected with the lower main pin boss; the nylon bush is arranged in the inner hole of the upper main pin base in an interference press-fitting manner; and the lower nylon bush is pressed in the inner hole of the lower main pin base in an interference fit manner.

Further, an inner hole, an outer circle and a bolt through hole are respectively formed in the upper main pin boss and the lower main pin boss; the upper nylon bush and the lower nylon bush are both cylindrical with inner holes, and the inner holes are matched with the main pin.

The utility model has the advantages that: 1. because the upper part and the lower part of the steering knuckle are designed in a notch mode, compared with the traditional closed structure and the structure with the tile cover, the structure is simple, the main pin can adopt an integral structure, and meanwhile, the assembly can be directly carried out through the notch part of the steering knuckle, so that the assembly and the maintenance are easy; 2. the nylon bush is arranged inside the automobile, so that the automobile has the advantages of light weight, low cost, good self-lubricating effect, better driving stability, higher reliability and lower cost.

Detailed Description

For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 1, 2, 3, 4 and 5, a mining front axle steering knuckle assembly comprises a steering knuckle 1, wherein the upper part and the lower part of the steering knuckle 1 are respectively provided with an open notch structure, a mounting plane and a threaded hole, the width of the notch is slightly larger than the diameter of a main pin, and components such as a tile falling cover, a positioning pin, a mounting bolt and the like are optimized; the upper main pin base 2 and the lower main pin base 4 are respectively provided with an inner hole, an excircle and a bolt through hole, the upper nylon bush 3 and the lower nylon bush 5 are both cylindrical with inner holes, the inner holes are matched with the main pins, and the bushes are made of nylon; an upper nylon bush 3 is press-fitted in an inner hole of an upper main pin base 2 in an interference manner, and a lower nylon bush 5 is press-fitted in an inner hole of a lower main pin base 4 in an interference manner; and then the upper kingpin base 2 is fixed on the mounting plane at the upper part of the steering knuckle 1 through a bolt 6, and the lower kingpin base 4 is fixed on the mounting plane at the lower part of the steering knuckle 1 through a bolt 6.

The utility model discloses a mining front axle knuckle assembly, knuckle breach position size just crosses the swizzle, can direct parallel mount to the swizzle on, upper and lower swizzle seat has the reinforcing effect to knuckle breach position through the bolt fastening in knuckle upper and lower portion, prevents simultaneously that the swizzle from deviating from; when the steering knuckle rotates around the main pin, the self-lubricating effect of the nylon bushing is better, and the running is more stable.

The above description is provided for the embodiments of the present invention with reference to the accompanying drawings, but these descriptions should not be construed as limiting the scope of the present invention, the scope of the present invention is defined by the appended claims, and any modification based on the claims is the scope of the present invention.
