Amphibious steering column for amphibious vehicle

Abstract

The invention belongs to the technical field of steering columns, and particularly discloses an amphibious steering column for an amphibious vehicle. The steering column comprises a lower shaft, an upper shaft, an outer shell, a combination and separation sleeve, a switching locking module and a damping automatic centering module, the lower shaft and the upper shaft are coaxially arranged in sequence, a first key groove is formed in the lower shaft, a second key groove is formed in the upper shaft, and a key groove is formed in the inner side wall of the outer shell; the combination and separation sleeve is arranged on the peripheries of the lower shaft and the upper shaft in a sleeving manner, an inner key is arranged on the inner side wall of the combination and separation sleeve, an outer key is arranged on the outer side wall, the inner key can slide in the first key groove and the second key groove, and the outer key can move in the axial direction; and the switching locking module and the damping automatic centering module are arranged on the outer side wall of the combination and separation sleeve, and the switching locking module is used for shifting the combination and separation sleeve to slide in the axial direction and lock the combination and separation sleeve so as to achieve the combination or separation of the upper shaft and the lower shaft and the combination and separation of the lower shaft and the outer shell. The steering column has a amphibious steering switching and locking mechanism, and a water steering automatic centering and damping function.

Description

technical field [0001] The invention belongs to the technical field of steering column, and more specifically relates to an amphibious vehicle amphibious steering column. Background technique [0002] Amphibious vehicles have two steering conditions: land steering and water steering, and there are large differences in actuators, system principles, and steering requirements between land steering and water steering. Land steering is transmitted to The steering gear is used to drive the wheels to turn. When turning on water, another set of devices needs to be manipulated to control the direction of the jet nozzle or the steering rudder. The steering devices under the two working conditions are often independent, so the system is more complicated. In addition, in order to reduce the resistance of water navigation, the wheels need to be lifted out of the water and locked in the neutral straight position, so as to avoid the occurrence of wheel damage to the vehicle body caused by ...

AI Technical Summary

Problems solved by technology

At the same time, after the steering column is separated, the steering gear does not have a locking function

In the field of intelligent driving, the clutchable steering column mainly relies on the return spring and the electromagnetic suction plate to realize the combination and separation, the control is complicated and the cost is high
