Steering column device

Abstract

The invention provides a steering column device. The device comprises a steering column, a dustproof sleeve and an automobile body metal plate floor located at the bottom of a cockpit, sponge is bonded to the mounting face, making contact with the automobile body metal plate floor, of the dustproof sleeve, a nylon bush is mounted on the inner side of an extending opening, a circle of protrusion is arranged in the middle of the outer side of the nylon bush, a circle of groove is further formed in the middle of the inner wall of the extending opening, the shape of the groove matches the shape of the protrusion, and the nylon bush is in interference fit with the dustproof sleeve. A lock hole is formed in the end, located in the cockpit, of the steering column, the steering column is connected with an ignition lock through the lock hole, at least two support installation platforms are arranged on the ignition lock, and combined switch supports are detachably installed on the support installation platforms. The steering column device has the beneficial effects that the dustproof function of a heavy truck is improved, the noise in the cab is reduced, the assembly of related accessories such as a combination switch is simplified, the assembly precision is improved, and the product reliability is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of steering column devices for heavy trucks, and in particular relates to a steering column device, which can improve the dustproof performance and reliability of the steering column device for heavy trucks and realize the integrated assembly of combined switch brackets. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements for the interior environment, noise and comfort of the cab. In the prior art, a dust cover is generally installed on the steering column device to prevent external dust from entering the cab and noise from entering the cab. Add combination switch bracket for accessory installation. However, there are some defects in the dust cover and the combination switch bracket installation structure of the steering column device of the existing heavy truck. [0003] In the prior art, the lower end of the protruding opening of...
