Abstract
The utility model relates to the field of motor steering shafts, in particular to a motor steering shaft medium joint shaft with a novel positioning structure. The motor steering shaft medium joint shaft comprises a universal joint fork, a medium joint shaft, a thrust sliding bearing, a shaft circlip, a sliding bearing and a sleeve support, wherein the medium joint shaft is connected with the universal joint fork, the sliding bearing is arranged in the sleeve support, and the thrust sliding bearing is in contact with the sliding bearing. According to the motor steering shaft medium joint shaft with the novel positioning structure, the thrust sliding bearing made of nylon and the common sliding bearing are together used for positioning, meanwhile, the thrust sliding bearing has functions of seal rings, the structure of a whole mechanism is simplified, the weight of the whole mechanism is greatly reduced, besides, compared with friction of traditional rolling bearings, the friction between bearings and the shaft is less, noises during operation are avoided, and the service life of the whole mechanism is prolonged.
Description
Technical field
The present invention and steering axles field, particularly save transmission shaft in a kind of steering axles with Novel positioning structure.
Background technique
In steering shaft, the supporting of nodal axisn is located traditionally, select a deep groove ball bearing to support, general supporting point is selected in the neutral position of middle nodal axisn, bearing is except bearing radial force, also need to bear axial force or even moment of flexure, very easily produce vibrations and noise with being coupling while touching, greatly reduce the working life of bearing, and relatively general sliding bearing, the cost of deep groove ball bearing is higher.Due to the close cab floor in middle joint mounting point, easily enter dust simultaneously, so the sealing of middle joint has strict requirement, usually adopt former and later two seal rings, this has increased weight and the cost of production of car load after the assembling undoubtedly.Therefore provide nodal axisn in a kind of steering axles with Novel positioning structure to have great importance.
The model utility content
The present invention is intended to address the above problem, and nodal axisn in a kind of steering axles with Novel positioning structure is provided.
For achieving the above object, the technical solution adopted in the present invention is as follows: nodal axisn in a kind of steering axles with Novel positioning structure, comprise: universal-joint fork, middle nodal axisn, thrust slide bearing, circlip for shaft, sliding bearing, bush support, wherein, described middle nodal axisn is connected with described universal-joint fork, described sliding bearing is arranged on described bush support inside, and described thrust slide bearing contacts with described sliding bearing.
Further, described middle nodal axisn two ends are connected with described universal-joint fork by spline, and described spline is extrusion modling.
Further, described middle nodal axisn one end is provided with the Step Shaft projection, and described sliding bearing one end contacts with this Step Shaft projection, and the sliding bearing the other end contacts with described thrust slide bearing.
Further, described circlip for shaft is arranged between sliding bearing and thrust slide bearing, better to clamp sliding bearing.
Further, the material of described thrust slide bearing is nylon, and thrust slide bearing inside has the step protruding structure, and during work, this step projection contacts with sliding bearing.
Further, described bush support is fixed on cab floor, and described bush support is threaded with described thrust slide bearing.
Nodal axisn in steering axles with Novel positioning structure provided by the invention, adopt thrust slide bearing and the conventional sliding bearing of nylon material jointly to position, thrust slide bearing plays the effect of seal ring simultaneously, whole mechanism structure is simplified, greatly alleviated the weight of whole mechanism, compared with traditional rolling bearing, reduced the friction between bearing and axle simultaneously, avoid the generation of noise in running, extended the working life of whole mechanism.
The accompanying drawing explanation
Fig. 1 is nodal axisn structural representation in the present invention
Fig. 2 is the axial sectional view schematic diagram of Fig. 1
In figure 1, upper cardan fork 2, middle nodal axisn 3, thrust slide bearing 4, circlip for shaft 5, sliding bearing 6, bush support 7, lower cardan fork.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As Fig. 1, shown in 2, middle nodal axisn 2 is connected with universal-joint fork 1 by the spline at two ends, to realize being linked of the two, one end of middle nodal axisn 2 is provided with the Step Shaft projection, this Step Shaft projection of sliding bearing 5 one ends and this contacts, the other end contacts with thrust slide bearing, in addition, also be provided with a circlip for shaft 4 between sliding bearing and thrust slide bearing, be used for better clamping sliding bearing, anti-skidding bearing 5 axial floats, sliding bearing 5 is arranged on the inside of bush support 6, tube stent 6 is fixedly connected with cab floor, bush support 6 is threaded with thrust slide bearing 3, wherein the material of thrust slide bearing is nylon, with the rolling bearing that tradition is used, compare, no longer metal be coupling tactile, therefore reduced the friction between bearing and axle, avoided the generation of a large amount of noises during work.During work, upper cardan fork 1 with on steering drive axle successively fork is connected, lower cardan fork 7 with successively pitch and be connected under steering drive axle, when upper joint transmission shaft rotation, pitch 1 by upper cardan middle nodal axisn is rotated, middle nodal axisn is pitched 7 by lower cardan again and is driven the rotation of lower joint transmission shaft.
Protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses, and the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
