Steering wheel connecting shaft dislocation device for automobile

Abstract

The invention discloses a steering wheel connecting shaft dislocation device. The steering wheel connecting shaft dislocation device comprises a shell, a rotating shaft and a gear fixed to the bottom of the rotating shaft; the interior of the bottom of the shell is connected with the side face of the rotating shaft through a tooth structure, the bottom face of the bottom of the shell is fixedly provided with an anti-collision gasket which has the same size as that of the bottom face of the bottom of the shell; a limiting shaft is fixed to the center of the top of the rotating shaft, a hollow structure for allowing the limiting shafts to be inserted is arranged in the shell, and the portion, over the hollow structure, in the shell is provided with a hollow section, a through hole structure for communicating the hollow section with the hollow structure is arranged between the hollow section and the bottom of the hollow structure, the portion, located at the bottom of the hollow structure, of the through hole structure is provided with a limiting head, a piston is arranged in the hollow section, a connecting rod is fixed to the center of the top of the piston, the top of the connecting rod is connected with a threaded plate, and the side face of the threaded plate is connected with the interior of the shell through a threaded structure. Accordingly, when collision occurs, a dislocation phenomenon can be generated; in addition, gas can be supplemented, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of automobile mechanical parts, in particular to a steering wheel connecting shaft dislocation device for automobiles. Background technique [0002] At present, in order to prevent the steering wheel from moving up and hurting the driver during the collision, a dislocation device is installed in the steering wheel connection shaft of the car. Once a collision occurs, the displacement can occur, which can effectively prevent the steering wheel from moving up. The current dislocation device uses the elasticity of the coil spring. When it hits, the error is relatively large, so the device has certain limitations. In addition, because the coil spring is exposed to the air for a long time, its performance will also decline. So there is a certain risk. [0003] In addition, there are some common car steering wheel connecting shafts. The rod body is divided into two parts. The two parts of the rod body are tangent...
