Steering column assembly and vehicle with same

Abstract

The invention discloses a steering column assembly and a vehicle having the same. The steering column assembly comprises a steering column, a fixed bracket and a shear ring. The fixed bracket is used for being fixedly installed to a vehicle body; the fixed bracket is provided with an energy absorption guide groove; the shear ring is fixedly connected to the steering column and the fixed bracket. When the impact exerted on the steering column is greater than a set threshold, the shear ring is disconnected with the fixed bracket and can perform energy absorption and slide in the energy absorption guide groove under the drive of the steering column. According to the invention, the connection space between the steering column and the fixed bracket is fully used, the crumple energy absorption structure is simplified, the arrangement space of the steering column assembly on the vehicle is decreased, the production cost is lowered, and the shear ring of the steering column assembly performs energy absorption and slides in the energy absorption guide groove and has a fixed trajectory.

Description

technical field [0001] The invention relates to the field of automobile steering systems, in particular to a steering column assembly and a vehicle with the same. Background technique [0002] During the frontal collision of the car, the front compartment of the car will be blocked by obstacles and move towards the driver, while the driver will move towards the steering wheel under the action of inertial force and hit the steering wheel. In order to reduce the impact on the driver National regulations require that the steering column in the steering system of an automobile has the function of collapsing and absorbing energy during a vehicle collision. [0003] In the prior art, the steering column mostly adopts special guide structures, energy-absorbing mechanisms and other auxiliary parts, so as to achieve the purpose of energy-absorbing collapse. A special guiding structure or energy-absorbing mechanism is used, but the space in the front cabin is narrow, which increases ...

AI Technical Summary

Problems solved by technology

A special guiding structure or energy-absorbing mechanism is used, but the space in the front cabin is narrow, which increases the difficulty of designing a special guiding structure or energy-absorbing mechanism, which not only increases the development cost of the steering column, but also makes the structure of the steering column too large. Complicated and affecting the arrangement of pipe strings on the vehicle
