Abstract
The utility model discloses a front axle assembly of a mine truck. The front axle assembly of the mine truck is characterized by comprising front shafts (1), a steering knuckle (5), a main pin base (15), a gasket (14), an upper nylon spacer (2), a lower nylon spacer (16), a rubber spacer (4), an adjusting spacer (3), a hub brake drum assembly (8), a hub inner bearing (9), a hub outer bearing (12), an oil seal base ring (7), a hub oil seal assembly (6), a sealing oil seal assembly (13), a rubber ring (10) and a locking nut (11). The front shaft and the steering knuckle (5) can meet requirements of high load bearing and a complicated structure, and the nylon spacers replace a thrust bearing and can not only meet bearing requirements but also has a certain self lubrication function. When the nylon spacers are used, the size structure does not need to be maintained. The rubber spacer is added to the front axle assembly, and the rubber spacer has a buffer function and has a certain protection function on the front axle assembly of the mine truck under a terrible road condition. Due to the fact that a sealing oil seal bearing and the rubber ring are added to the hub brake drum assembly, the sealing effect and the lubricating effect are improved, and maintaining frequency of the hub inner bearing and the hub outer bearing is reduced.
Description
Technical field
The utility model belongs to mining car vehicle bridge technical field, is specifically related to a kind of mining car front axle assy.
Background technology
Domestic mining car has been widely used in the heavy construction transportation at present, and the user requires more and more higher to reliability, the ease for maintenance of mining car.But domestic 6 * 4 traditional mining car front axle assy structural reliabilities are low, the maintenance is inconvenient, cause mining car front axle assy damage of components, and for example: preceding axle fracture, steering swivel fracture, hub bearing damage, the stub thrust bearing is along fault such as bad.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of mining car front axle assy is provided, and mainly solves existing mining car front axle assy front axle easy fracture, steering swivel easy fracture, fault such as hub bearing is fragile and thrust bearing is fragile.
The technical solution of the utility model is: a kind of mining car front axle assy, its special character are that front axle assy comprises front axle, steering swivel, stub seat, packing ring, following nylon spacer, rubber sheet gasket, adjustment pad, wheel hub brake drum assembly, hub inner bearing, wheel hub outer bearing, oil sealing seat ring, hub oil seal assembly, sealing oil seal assembly, rubber ring, jam nut, goes up nylon spacer; Weld stub on the described front axle, the stub seat is installed on the stub of front axle welding, and steering swivel is assemblied on the front axle by the stub seat, and the stub that welds on front axle freely rotates; In the stub seat of steering swivel bottom, set nylon spacer, packing ring, in the stub seat of steering swivel top, establish nylon spacer, adjust pad and rubber sheet gasket, establish the oil sealing seat ring at steering swivel, in the outer ring that wheel hub brake drum assembly wheel hub inner chamber is established hub oil seal assembly, rubber ring, sealing oil seal assembly, hub inner bearing, wheel hub outer bearing, establish the inner ring of inner ring, wheel hub brake drum assembly and the wheel hub outer bearing of hub inner bearing at steering swivel, establish jam nut at steering swivel.
A kind of mining car front axle assy described in the utility model compared with prior art has following good effect: 1, front axle, steering swivel can be realized the requirement of high-mechanic, labyrinth; 2, nylon spacer replaces thrust bearing, both can satisfy the requirement of carrying, and have certain self-lubricating function, does not need in the use dimensional structure is safeguarded; 3, increase rubber sheet gasket, play cushioning effect, under abominable road conditions, mining car front axle assy is had the certain protection effect; 4, increase sealing sealed-bearing, rubber ring in the wheel hub brake drum assembly, improve sealing and lubricant effect, reduce hub inner bearing, wheel hub outer bearing maintenance number of times.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the I position enlarged drawing of Fig. 1;
Fig. 3 is the II position enlarged drawing of Fig. 1.
The drawing explanation:
1 front axle; Nylon spacer on 2; 3 adjust pad; 4 rubber sheet gaskets; 5 steering swivels; 6 hub oil seal assemblies; 7 oil sealing seat rings; 8 wheel hub brake drum assemblys; 9 hub inner bearings; 10 rubber rings; 11 jam nuts; 12 wheel hub outer bearings; 13 sealing oil seal assemblies; 14 packing rings; 15 stub seats; 16 times nylon spacers.
The specific embodiment
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail.
Embodiment 1, referring to Fig. 1, at first, steering swivel 5 is assemblied on the stub of welding on the front axle 1 by stub seat 15, and the stub that can weld on front axle 1 freely rotates; To descend nylon spacer 16, pad 14 to be assemblied in the stub seat 15 of steering swivel 5 bottoms then, and carry out shutoff; To go up nylon spacer 2 again, adjust pad 3, rubber sheet gasket 4 is loaded in the stub seat 15 on steering swivel 5 tops, carries out after the gap adjusts, and with the shutoff of stub seat, replaces thrust bearing in the present front axle assy with nylon spacer, increases rubber sheet gasket simultaneously; Oil sealing seat ring 7 is assemblied in steering swivel 5; Again hub oil seal assembly 6, rubber ring 10, sealing oil seal assembly 13, the outer ring of hub inner bearing 9, the outer ring of wheel hub outer bearing 12 are assemblied in wheel hub brake drum assembly 8, make wheel hub brake drum assembly 8 on traditional architecture basics, increase sealing oil seal assembly 13, rubber ring 10; The inner ring of hub inner bearing 9 is assemblied in steering swivel 5, then the above-mentioned wheel hub brake drum assembly 8 that assembles is assemblied in steering swivel 5, at last, the inner ring of wheel hub outer bearing 12 is assemblied in steering swivel 5, hub inner bearing 9, wheel hub outer bearing 12 excessively cooperate with steering swivel 5; Be assemblied on the steering swivel 5 by screw thread fit with jam nut 11 then, and adjust bearing space, jam nut 11 also plays the effect of oil sealing seat ring simultaneously.
Below by reference to the accompanying drawings the specific embodiment of the present utility model is described; but these explanations can not be understood that to have limited scope of the present utility model; protection domain of the present utility model is limited by the claims of enclosing, and any change on the utility model claim basis all is protection domain of the present utility model.
