Description

Steering intermediate shaft assembly and automobile

Technical Field

The utility model relates to a vehicle field especially indicates a turn to jackshaft assembly and car.

Background

Along with the rapid development of social economy, people who like the off-road vehicle are more and more, and the road condition of the off-road vehicle is worse, so the performance requirement on automobile parts is higher. The current telescopic spline type steering intermediate shaft is widely used due to lower cost. In order to ensure the sealing property of the steering intermediate shaft and prevent abnormal abrasion of the spline caused by the entering of silt, the steering intermediate shaft is abnormal in sound, and a plug is welded at the upper end of the steering intermediate shaft generally. In order to ensure lower axial force of the steering intermediate shaft, a layer of grease is coated on the spline of the steering intermediate shaft, so that the axial force of the steering intermediate shaft is reduced. The plug of the upper end of the existing telescopic spline type steering intermediate shaft is welded and cannot be detached, and grease cannot be filled in the later period for maintenance, so that the axial force is too large, and the steering system is affected to collapse during collision, so that the safety is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a turn to jackshaft assembly and car, the current end cap that turns to the jackshaft upper end is welded, can't dismantle, and the unable filling grease in later stage is maintained, leads to the axial force too big, influences the steering system and crumples during the collision, leads to the security to reduce.

In order to solve the above technical problem, an embodiment of the present invention provides the following solutions:

a steering intermediate shaft assembly comprises a first section fork, a second section fork, a spline shaft, a spline housing, a third section fork and a fourth section fork,

the first section fork and the second section fork are connected through a first cross shaft, the second section fork is fixedly connected with the spline shaft, and the spline shaft is sleeved with a spline sleeve;

the outer side wall of the end part of the spline sleeve is fixedly connected with the third fork, a detachable plug is arranged at one end of the spline sleeve connected with the third fork, and a sealing ring is arranged at the other end of the spline sleeve;

and the third section fork and the fourth section fork are connected through a second cross shaft.

The plug is made of elastic materials, is arranged in the spline sleeve and is connected with the spline sleeve in an interference fit mode.

The plug is provided with a through hole, a bolt is installed in the through hole, the end of the screw rod of the bolt is provided with a thin gasket, and two sides of the thin gasket are respectively provided with a first thin nut and a second thin nut.

The plug is made of rubber.

An automobile comprises the steering intermediate shaft assembly.

The above technical scheme of the utility model at least include following beneficial effect:

the above technical scheme of the utility model, the end cap that turns to the jackshaft upper end adopts detachable construction, has both guaranteed turn to the leakproofness of jackshaft, make its silt road conditions who is applicable to cross country vehicle betterly, the later stage filling grease of also being convenient for simultaneously maintains it.
