Description

Four-wheel all-terrain vehicle direction post mounting structure

Technical field

The utility model relates to the four-wheel all-terrain vehicle, specifically refers to the mounting structure of four-wheel all-terrain vehicle direction post on vehicle body.

Background technology

The four-wheel all-terrain vehicle mainly travels on the soft sandy beach, just because of its special field of employment, for some structure special requirement is arranged.For example the direction post just requires rotation more flexible than common motor bike, otherwise the control of direction is difficult more, and big end float misalignment can not be arranged, and this all will bring difficulty to the control of direction.Existing common direction post mounting structure as shown in Figure 1, direction post 1 is one-body molded, direction post upper end and 15 welding of handle pipe mount pad, lower end and spindle arm 6 are fixing, though this structure is simple, parts are few, economy, but the very flexible of rotating, feel is tightly puckery, clamping stagnation is obvious, and travel direction is very difficult to control on the sandy beach.Four-wheel all-terrain vehicle direction post mounting structure after a kind of the improvement as shown in Figure 2, the direction post is formed by connecting by universal-joint 17 by two sections, fixing by upper plate 18 on epimere direction post 1-1 with handle pipe mount pad 15, on hypomere direction post 1-2, be provided with spindle arm 6, on vehicle frame, be provided with direction post lower support 11, be provided with lower bearing 5 in the direction post lower support 11, hypomere direction post 1-2 passes from lower bearing 5, on hypomere direction post 1-2, be provided with lining 19, directly produce application force in the axial direction to avoid hypomere direction post and lower bearing.Though the more common direction post of the structure after the improvement rotates alerting ability and is improved, complex structure, the part processing difficulty increases, especially after the direction post constitutes by two sections, processing and be connected work and increase, the installation of direction post self simultaneously becomes complicated, influences the efficiency of assembling of direction post.

The utility model content

At the prior art above shortcomings, the purpose of this utility model provides a kind of direction post does not have play, rotate four-wheel all-terrain vehicle direction post mounting structure more flexibly.

The technical solution of the utility model is achieved in that four-wheel all-terrain vehicle direction post mounting structure, it comprises direction post, spindle arm and handle pipe mount pad, (passing through bearing cap shim) is provided with head bearing in vehicle frame direction post standpipe, on vehicle frame, be provided with direction post lower support, be provided with lower bearing in the direction post lower support and by back-up ring chucking, the direction post passes from head bearing and lower bearing; The handle pipe mount pad is provided with sleeve, and sleeve is placed in direction post upper end and by bolt sleeve and direction post is locked; Spindle arm is placed in direction post lower end by spline and locks by jam nut.

Described lower bearing is the aligning oscillating bearing, is provided with lining I between lower bearing and back-up ring; Head bearing is a tapered roller bearing, is provided with the lining II that head bearing is compressed between head bearing and sleeve.

Between jam nut and spindle arm, be provided with flat gasket and spring washer, so that the jam nut non-loosening.

Described jam nut is a hexagon slotted nut, and a spring cotter passes hexagon slotted nut and the direction post lock onto hexagon slotted nut on the direction post, and this structure has guaranteed that further jam nut can not become flexible.

Compared to existing technology, the utlity model has following beneficial effect:

1, the production fitting process is fairly simple, improves efficiency of assembling.

2, direction post upper end, reduces the concentricity requirement of upper end vehicle frame direction post standpipe with following extreme direction post mount pad welding with the assembling of aligning oscillating bearing greatly with tapering bearing, lower end.

3, because direction post and spindle arm are by spline fitted, reduce steering gap, effectively improved the alerting ability that the four-wheel all-terrain vehicle turns to, alleviated the feel of steering operation, improved maneuvering performance.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Referring to Fig. 3, from the figure as can be seen, the utility model four-wheel all-terrain vehicle direction post mounting structure, it comprises direction post 1, spindle arm 6 and handle pipe mount pad 15, in vehicle frame direction post standpipe, be provided with head bearing 3 by bearing cap shim 2, be provided with direction post lower support 11 on vehicle frame, be provided with lower bearing 5 in the direction post lower support 11 and pass through back-up ring 4 chuckings, direction post 1 passes from head bearing 3 and lower bearing 5.Handle pipe is installed in handle pipe mount pad 15, is set with sleeve 16 on handle pipe mount pad 15, and sleeve 16 is placed in direction post 1 upper end.Be provided with connecting bore on sleeve and direction post, bolt 14 passes connecting bore with

sleeve

16 and 1 locking of direction post.Spindle arm 6 is placed in direction post 1 lower end and by jam nut 8 lockings spindle arm 6 is close on the lower bearing 5 by spline.

In order to reduce vehicle frame direction post standpipe and following extreme direction post mount pad welding concentricity requirement, described lower bearing 5 is selected the aligning oscillating bearing for use, is provided with lining I 10 between lower bearing 5 and back-up ring 4; And head bearing 3 is selected tapered roller bearing for use, is provided with the lining II 13 that head bearing is compressed between head bearing 3 and sleeve 16, scurries on the head bearing 3 preventing.
