Description

A kind of car steering tube column

Technical field

This utility model relates to technical field of automobile parts, more specifically a kind of car steering tube column.

Background technology

At present, the electric hydraulic power-assisted steering used on existing domestic motor bus, new forms of energy car and electric coach The commonly used flow controlling steering according to GES in system EHPS, reaches the purpose of power steering, but all Have ignored wheel steering angle and steering moment signal, make EHPS systemic-function not perform to ultimate attainment；Along with people are to greatly Passenger vehicle, newly energy energy passenger vehicle and the raising of electric coach performance requirement, automatically controlled smooth ride system Electronic Stabilty Program(is called for short ESP) gradually can find application at motor bus, integral new-energy passenger and electric coach, ESP system System equally can gather steering wheel wheel steering angle and steering moment signal, the side of being integrated with the most not being suitable for To the angle steering gear of dish steering angle and steering moment signals collecting, it is simply that because there is no a kind of suitably steering angle, turning to Torque signals harvester.

Summary of the invention

For overcoming the deficiencies in the prior art, this utility model provides one can provide steering angle and steering moment defeated A kind of car steering tube column gone out.

For achieving the above object, a kind of car steering tube column that this utility model provides, including protective cover, tubing string, turn to Circle, protecgulum, upper bracket, lower carriage under axle, torsion bar, bearing pin, lower axle, end cap, sea pull sensor body, sea pull sensor；It is special Levy and be: tubing string is bolted with protective cover by being welded on the protecgulum of tubing string lower end, be provided with in tubing string center cavity Steering spindle, steering spindle lower end is connected with lower axle, and described lower axle is quill shaft, and steering spindle lower surface is centrally along the axial side of steering spindle To offering a blind hole, torsion bar is stretched in described blind hole through lower axle center cavity and is connected with steering spindle by bearing pin, described Torsion bar and lower axle interference fit.

It is welded with end cap in described protective cover；End cap central is provided with bearing, and lower axle and described bearing are suitable；Described turn The end being positioned at protective cover to axle is provided with a round end key-like boss in round end key-like, sea pull sensor body and round end Key-like boss is fixing to be connected；The axial facade of round end key-like boss assumes diamond in shape convex shape；Lower axle is in the end face of steering spindle one end The heart is provided with strip groove, and described strip groove is suitable with described round end key-like boss；Biography is drawn in described lower axle outer surface and sea Under sensor, circle is fixing connects.

The beneficial effects of the utility model are: this utility model clear principle, simple in construction, using the teaching of the invention it is possible to provide steering angle and Steering moment signal, makes automatically controlled smooth ride systemic-function perform to ultimate attainment.

Accompanying drawing illustrates:

Accompanying drawing 1 is structural representation of the present utility model；

Accompanying drawing 2 is the structural representation that round end key-like boss of the present utility model coordinates with bar-shaped trough；

In accompanying drawing: 1, protective cover, 2, tubing string, 3, steering spindle, 4, torsion bar, 5, bearing pin, 6, lower axle, 7, end cap, 8, Hai Lachuan Sensor body, 9, enclose under the pull sensor of sea, 10, protecgulum, 11, upper bracket, 12, lower carriage.

Detailed description of the invention:

Clearer, below in conjunction with this utility model for the purpose making this utility model implement, technical scheme and advantage Accompanying drawing, this utility model is further described in more detail.

To in description of the present utility model, it is to be understood that being described as based on attached of indicating position or position relationship Orientation shown in figure or position relationship, be for only for ease of description this utility model and simplify description rather than instruction or hint The device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this The restriction of utility model protection scope.

In fig. 1 and 2, a kind of car steering tube column that this utility model provides, including protective cover 1, tubing string 2, turn to Axle 3, torsion bar 4, bearing pin 5, lower axle 6, end cap 7, sea pull sensor body 8, sea pull sensor under enclose 9, protecgulum 10, upper bracket 11, Lower carriage 12；It is characterized in that: tubing string 2 is bolted with protective cover 1 by being welded on the protecgulum 10 of tubing string 2 lower end, pipe Being provided with steering spindle 3 in post 2 center cavity, steering spindle 3 lower end is connected with lower axle 6, and described lower axle 6 is quill shaft, steering spindle 3 times End face offers a blind hole centrally along the axial direction of steering spindle 3, and torsion bar 4 stretches in described blind hole through lower axle 6 center cavity And be connected with steering spindle 3 by bearing pin 5, described torsion bar 4 and lower axle 6 interference fit.

Described protective cover 1 is metal plate punching part, interior welding metal plate punching part end cap 7；End cap 7 is provided centrally with bearing, under Axle 6 and described bearing are suitable；The end that described steering spindle 3 is positioned at protective cover 1 is provided with a round end in round end key-like Key-like boss, sea pull sensor body 8 is fixing with round end key-like boss to be connected；The axial facade of round end key-like boss assumes diamond in shape projection Shape；The lower axle 6 end face near steering spindle one end is provided centrally with strip groove, described strip groove and described round end key-like boss Suitable, rhombus projection limits the steering spindle 3 rotational angle relative to lower axle 6, and protection torsion bar 4 will not damage because of inordinate rotation Bad；Described lower axle 6 outer surface is connected with under the pull sensor of sea, circle 9 is fixing.
