Abstract
The utility model provides an automobile-used electronic tubular column lower shaft assembly device which characterized in that: the lower shaft assembly device of the vehicular electric pipe column comprises an electric steering pipe column assembly, a combination bolt and a transmission shaft assembly; wherein: the electric steering column assembly is connected with the transmission shaft assembly through a combination bolt. The transmission shaft assembly adopts a dotting interference fit structure, namely a press-riveting structure. The utility model has the advantages that: automobile-used electric tubular column lower shaft assembly device, the impact load that steering column can bear is adjusted. Interference fit does not influence under the non-atress condition and turns to, and when the car bumps and assaults and reach certain degree, the lower axle assembly relative motion of electric column area played the effect of absorbing the collision energy, can adjust the impact load that steering column can bear.
Description
Technical Field
The utility model relates to an automobile steering mechanism field, in particular to automobile-used electronic tubular column lower shaft assembly device.
Background
The existing lower shaft assembly structure of the electric tubular column for the vehicle generally has higher requirements on the processing sizes of an upper tubular column and a lower tubular column. After the parts produced in the same batch are assembled, the shock absorption capacity of the assembly is greatly different due to dimensional tolerance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the above problem, and in particular provides an automobile electric tubular column lower shaft assembly device.
The utility model provides an automobile-used electronic tubular column lower shaft assembly device, its characterized in that: the vehicular electric pipe column lower shaft assembly device comprises an electric steering pipe column assembly 1, a combination bolt 2 and a transmission shaft assembly 3; wherein: the electric steering column assembly 1 is connected with the transmission shaft assembly 3 through the combination bolt 2.
The transmission shaft assembly 3 adopts a dotting interference fit structure, namely a press-riveting structure.
And a universal joint device is arranged between the electric steering column assembly 1 and the transmission shaft assembly 3.
The two end parts of the transmission shaft assembly 3 are provided with universal joint devices
Wherein: the electric steering column assembly 1 is connected with the transmission shaft assembly 3 through the combination bolt 2.
The transmission shaft assembly is pressed and riveted by adopting a dotting interference structure, so that abnormal sound caused by clearance caused by spline fit can be eliminated. For the round pin isotructure of moulding plastics of other products, the crushing force is more stable, and assembly efficiency is more high-efficient.
The utility model has the advantages that:
