Problems solved by technology

However, the above designs have a big disadvantage that they are very destructive. In the steering system of the damaged vehicle, except for the steering wheel, almost all other parts need to be replaced, which is inconvenient for maintenance and high in cost.

Abstract

The invention discloses a reusable energy-absorbing steering column of an automobile. The reusable energy-absorbing steering column comprises a steering wheel and a steering shaft, and is characterized in that the steering shaft is connected with a hollow shaft by three plastic pins which are circumferentially and uniformly distributed, a sleeve is connected onto the hollow shaft by a clamp ring, a compression spring is arranged in the hollow shaft, the upper end of the compression spring sleeves a shaft end of the steering shaft, the lower end of the compression spring is arranged in a compression spring stop table arranged at a head end of the hollow shaft, a first slider and a second slider are arranged on the steering shaft and are connected with each other by a light compression spring arranged between the first slider and the second slider, and an annular clamp groove is formed in the hollow shaft and is positioned in the middle of the sleeve. The reusable energy-absorbing steering column has the advantages of reasonable structure, convenience in assembling and disassembling, good safety, low maintenance cost and the like. Besides, secondary injury to drivers can be prevented by the aid of the reusable energy-absorbing steering column.

Description

technical field [0001] The invention relates to an automobile steering device, which is a reusable automobile energy-absorbing steering column. Background technique [0002] At present, there are many specific structural forms of energy-absorbing steering columns, but the basic principle of various forms of energy-absorbing steering columns is the same, that is, to effectively absorb the secondary impact of the driver and the steering column system when the car collides head-on. Collision energy, protect the driver's safety. There are many types of energy-absorbing steering columns, the most common of which are sleeve-type and mesh column-type energy-absorbing steering columns. The working principle of the mesh energy-absorbing steering column is: when the car has a frontal collision, the collision first cuts the injection pin in the connection box, so that the steering system is disengaged from the body, and the mesh part on the steering column is compressed after 3-5ms ,...
