Dislocation type rotating shaft for connection of automobile steering wheel

Abstract

The invention discloses a dislocation type rotating shaft for connection of an automobile steering wheel. The dislocation type rotating shaft comprises a middle rotating shaft. When the dislocation phenomenon does not occur, a steering wheel rotating shaft can drive the middle rotating shaft and a worm connecting shaft to rotate under the pressure action of a first inclined face, a second inclined face and a main spiral spring, and the normal rotation driving function is achieved; when dislocation phenomenon occurs, the force from the lower portion enables the middle rotating shaft to move towards one side under the action of the first inclined face and the second inclined face; and when the axis position of the steering wheel rotating shaft and the axis position of the worm connecting shaft and the axis position of the middle rotating shaft are completely staggered, a safe moving distance exists between the steering wheel rotating shaft and the worm connecting shaft, so that the case that the shaft body hurts people due to dislocation can be prevented. In the aspect of control capability, control is carried out by utilizing the radial elastic force of the spiral spring, so that the elasticity of the spiral spring is effectively utilized; and the spiral spring is positioned in the part, so that the negative influence of the external environment on the spiral spring can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automobile components, in particular to a dislocation rotating shaft for connecting automobile steering wheels. Background technique [0002] At present, in order to prevent the occurrence of personnel damage caused by the directional movement of the steering wheel due to the directional movement of the connecting rotating shaft when the car collides, dislocation-connected shafts are used. Most of the existing dislocation-connected rotating shafts are limited by coil springs. In actual work, due to the continuous exposure of the coil spring, its elasticity and its own performance are greatly reduced, and there is a great potential safety hazard. Contents of the invention [0003] The object of the present invention is to provide a dislocation rotating shaft for connecting the steering wheel of an automobile, so as to solve the problems raised in the background technology above. [0004] In order to ach...
