Abstract
The utility model relates to a relevant part of vehicle, in particular to a vehicle front axle device, which comprises a knuckle, a front shaft, a knuckle bushing and an adjusting gasket; the knucklebushing is arranged in a knuckle hole; seal rings are arranged above and below the knuckle bushing. The knuckle bushing is free of processing and is not needed to be reprocessed by directly pressing the knuckle bushing into the knuckle hole. Rubber sealing parts are increased, which reduces the possibility that lubricating grease leaks to the outside.
Description
Technical field
The utility model relates to the associated components of automobile, a kind of specifically automobile front axle device.
Background technology
No matter be that Light-duty Vehicle or the employed steering knuckle bush of heavy goods vehicles propons are will approach the copper alloy layer sintering earlier to roll into cylindrical behind steel backing on the market at home at present, after being pressed in the knuckle bores then steering swivel belt material cover assembly one is reinstated reamer and process again, reach the size of expection.The good oil groove of processing in advance or extruding is arranged on the steering knuckle bush, grease is injected oil groove, reach lubricating effect.Generally when the 4000-5000 kilometer, need to motor all-purpose grease of steering knuckle bush filling when the propons of this kind structure maintains, and, have a strong impact on steering safety in case untimely maintenance can cause lining and stub to wear and tear fast.
Existing automobile front axle structure as shown in Figure 1, respectively there is a fist shape part at front axle 4 two ends, and through hole is arranged, and are connected with left and right steering swivel 6 by stub 2, with screwed wedge shape lock pin stub 2 are fixed in the front-axle hole, and it can not be rotated relative to front axle 4.When motor turning, steering drop arm is swung in longitudinal plane, by steering drag link, vertical pulling lever arm, left and right sides spindle arm and tierod, handles vehicle front and turns over certain angle, thereby change the travel direction of automobile.Steering knuckle bush 1 forms for bimetal liner rolls, and mainly plays wear-resisting effect.In left and right steering swivel 6 sides lubrication adapter 7 is housed, oil is clamp-oned in the oil groove of lining, to reduce wearing and tearing by lubrication adapter 7.Adjust the clearance between steering swivel 6 and the front axle 4 has adopted one group bearing cap shim 3.When assembling,, come control gap with measuring the initial moment size of steering swivel 6 when front axle 4 rotates.To turn to lightly flexibly in order making, thrust bearing 5 to be housed between the ear under front axle lower end and the steering swivel.Existing this automobile front axle structure has been taked seal approach at steering swivel 6 upper and lower end faces, and steering swivel 6 and front axle 4 contact surfaces are not taked any seal approach, easily extrudes from bearing cap shim 3 and thrust bearing 5 when injecting grease.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming that above prior art exists, propose a kind of steering knuckle bush and exempt from processing, reduce lubricating grease to external leakage, the automobile front axle device that maintenance cycle is obviously reduced.
The technical scheme that the utility model solves above technical matters is:
The automobile front axle device comprises steering swivel, front axle, steering knuckle bush and bearing cap shim, and steering knuckle bush is located in the knuckle bores, all is provided with seal ring up and down at steering knuckle bush.
Automobile front axle device of the present utility model, the upper-lower seal circle of steering knuckle bush is a v-ring.Also be provided with an O-ring seals at the bearing cap shim place.
The utility model is compared with existing preceding bridge construction, and have the following advantages: (1) steering knuckle bush is exempted from processing, and steering knuckle bush directly is pressed in the knuckle bores, need not reprocessing; (2) rubber seal increases, and has reduced the possibility of lubricating grease to external leakage; (3) maintenance cycle is obviously reduced, propons only needs when the 80000-100000 kilometer to motor all-purpose grease of steering knuckle bush filling, prolonged the life-span of steering knuckle bush, the corresponding damage of part when having reduced frequency of maintenance and dismounting has also reduced the grease consumption.
Description of drawings
Fig. 1 is existing automobile front axle structural representation.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 2, a kind of automobile front axle device, comprise steering swivel 6, front axle 4, steering knuckle bush 1 and bearing cap shim 3, steering knuckle bush 1 is located in the knuckle bores, in order to improve the sealing property of structure, at the v-ring of increase up and down 8 (being highly resistant to outside contamination) of steering knuckle bush 1.Roughness＜the 0.4mm on stub surface, diameter dimension class of accuracy are h8, and steering swivel diameter of bore dimensional accuracy grade is H7.The steering knuckle bush 1 that will have v-ring 8 directly is pressed in the knuckle bores, need not reprocessing.The lubricated of steering knuckle bush 1 also has an O shape to enclose 9 by two ends lubrication adapter 7 injections up and down at bearing cap shim 3 places, also can effectively stop overflowing of grease.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
Claims (4)
1. the automobile front axle device comprises steering swivel, front axle, steering knuckle bush and bearing cap shim, and described steering knuckle bush is located in the knuckle bores, it is characterized in that: all be provided with seal ring up and down at described steering knuckle bush.
2. automobile front axle device as claimed in claim 1 is characterized in that: described seal ring is a v-ring.
