Abstract
The invention relates to an air-tight steering telescopic shaft which sequentially comprises an upper rotating shaft, a first universal joint, a telescopic shaft spline housing, a telescopic spline shaft, a second universal joint, a lower steering shaft and a third universal joint from top to bottom, wherein the upper end of the upper rotating shaft is connected with a steering wheel through a spline, the lower end of the upper rotating shaft is connected with the upper end of the telescopic shaft spline housing through the first universal joint, and the upper end of the telescopic spline shaft is provided with an external tooth spline. The invention has the advantages that: the sliding bearing seat is connected with the connecting seat in a spherical surface hinged mode, the connecting seat is installed on the floor of the vehicle body through a bolt, the contact surface is good in sealing, and the sliding bearing seat can meet the requirement that each degree of freedom of the lower steering shaft in the use adjusting range is flexible in operation.
Description
Technical field
The present invention relates to a kind of airtight sexual deviation telescopic shaft, belong to mechanical engineering transmission device field.
Background technology
The function for turning to telescopic shaft is that the steering moment that driver acts on steering wheel is passed into steering gear, its top
It is connected with the steering wheel in vehicle body, bottom is connected with the steering gear of body exterior.Turn to the rotation that telescopic shaft is insertion body platform
Transhipment dynamic component.The structure type, for the vehicle body that has seal request, is a prominent unfavorable factor.Vehicle is driven to improve
The riding comfort of personnel, vehicle body will not be used with vehicle frame and is rigidly connected, but use rubber mounting or suspension spring to buffer
And the vibration of the vehicle frame upper end transmission that decays.So, in vehicle travel process, vehicle body and vehicle frame can occur vertical relative bounce and
Laterally, the torsion of longitudinal direction.To solve to turn to sealing problem of the telescopic shaft at body platform, such as conventional steering telescopic shaft is existed
Directly fixed on body platform, when vehicle body and vehicle frame relative position change, telescopic shaft will occur clamping stagnation, influence vehicle
Turning function and driving safety.
The content of the invention
To overcome the defect of prior art, the present invention to provide a kind of airtight sexual deviation telescopic shaft, technology of the invention
Scheme is：
A kind of airtight sexual deviation telescopic shaft, includes top rotary shaft, the first universal joint, telescopic shaft spline successively from top to bottom
Set, extension shaft, the second universal joint, lower steering shaft and the 3rd universal joint, the upper end of the top rotary shaft by spline with
Steering wheel is connected, and lower end is connected by the first universal joint with telescopic shaft spline set upper side, and the upper end of the extension shaft is set
There is external spline, stretched in telescopic shaft spline housing from the lower end of flexible spline housing, the extension shaft is slided with flexible spline housing
Dynamic to coordinate, the lower end of the extension shaft is connected by the second universal joint with the upper end of lower steering shaft, and described bottom turns to
Axle is arranged on bearing seat assembly, and is connected with steering gear by the 3rd universal joint.
Described bearing seat assembly includes plain bearing housing, bushing, connecting seat, dust ring and back-up ring, and described bottom turns
To axle through the centre bore of plain bearing housing, it is slidably mounted on plain bearing housing, the lower steering shaft and plain bearing housing
Between be sequentially installed with bushing, dust ring and back-up ring from top to bottom, described connecting seat is arranged on the periphery of plain bearing housing, with
Linked together by the way of sphere is hinged between plain bearing housing, the connecting seat is arranged on underbody by bolt.
It is an advantage of the invention that：Plain bearing housing is connected by way of sphere is hinged with connecting seat, and connecting seat passes through spiral shell
Bolt is arranged on body platform, contact surface good seal, and plain bearing housing can meet lower steering shaft and use regulation model
Each free degree in enclosing goes slick.
Brief description of the drawings
Fig. 1 is agent structure schematic diagram of the invention.
Fig. 2 is the structural representation of Fig. 1 bottom bracket assemblies.
Specific embodiment
Further describe the present invention with reference to specific embodiment, advantages of the present invention and feature will be with description and
It is apparent.But these embodiments are only exemplary, do not constitute any limitation to the scope of the present invention.People in the art
Member to the details of technical solution of the present invention and form it should be understood that can enter without departing from the spirit and scope of the invention
Row modification is replaced, but these modifications and replacement are each fallen within protection scope of the present invention.
Referring to Fig. 1 and Fig. 2, the present invention relates to a kind of airtight sexual deviation telescopic shaft, rotated including top successively from top to bottom
Axle 2, the first universal joint 3, telescopic shaft spline housing 4, extension shaft 5, the second universal joint 6, the universal joint of lower steering shaft 7 and the 3rd
9, by being sequentially connected for above-mentioned part, such that it is able to realize that driver will operate the moment of torsion of steering wheel, it is transferred to turn to successively
Device, realizes the turning function of vehicle.The upper end of the top rotary shaft 2 is connected by spline with steering wheel 1, and lower end passes through the 10000th
It is connected with the upper end of telescopic shaft spline housing 4 to section 3, the upper end of the extension shaft 5 is provided with external spline, from flexible spline housing
4 lower end is stretched in telescopic shaft spline housing 4, and the extension shaft 5 is slidably matched with flexible spline housing 4, so as in occupant's post
When vehicle body is beated when pipe is adjusted or in vehicle travel process, the need for meeting the axial length regulation of telescopic shaft of the present invention；This is stretched
The lower end of contracting splined shaft 5 is connected by the second universal joint 6 with the upper end of lower steering shaft 7, and described lower steering shaft 7 is arranged on
On bearing seat assembly 8, and it is connected with steering gear by the 3rd universal joint 9.
Described bearing seat assembly includes plain bearing housing 10, bushing 11, connecting seat 12, dust ring 13 and back-up ring 14, institute
The lower steering shaft 7 stated is slidably mounted on plain bearing housing 10 through the centre bore of plain bearing housing 10, and the bottom turns to
Bushing 11, dust ring 13 and back-up ring 14, described connecting seat 12 are sequentially installed between axle 7 and plain bearing housing 10 from top to bottom
The periphery of plain bearing housing 10 is arranged on, is linked together by the way of sphere is hinged between plain bearing housing 10, the company
Joint chair 12 is arranged on underbody by bolt.
Plain bearing housing is connected by way of sphere is hinged with connecting seat, and connecting seat is arranged on body platform by bolt
