Electric retractable suspension system for amphibious vehicles

Abstract

The invention relates to a suspension system for amphibious vehicles and belongs to the field of vehicle engineering. The suspension system comprises a suspension guide mechanism lower cross arm, a suspension guide mechanism upper cross arm, a spring, an electric cylinder, a steering knuckle, a wheel and a shock absorber, and a peripheral part comprises a vehicle body. The wheel is connected with the steering knuckle, the lower end of the steering knuckle is in hinged connection with the suspension guide mechanism lower cross arm, the upper end of the steering knuckle is in hinged connection with the suspension guide mechanism upper cross arm, the middle of the suspension guide mechanism lower cross arm is in hinged connection with the shock absorber, the right end of the suspension guide mechanism upper cross arm is in hinged connection with the vehicle body, the electric cylinder is used for providing power for retracting the wheel by means of retractable movement and is locked by means of reverse self locking, the spring and the shock absorber are parallelly connected on the lower portion of the electric cylinder, and a suspension guide mechanism and the electric cylinder are respectively in hinged connection with the vehicle body. Driving resistance of the amphibious vehicles in water can be fundamentally reduced, and driving speed of the amphibious vehicles in water can be increased.

Description

technical field [0001] The invention relates to a vehicle suspension system, in particular to a suspension system for amphibious vehicles, which belongs to the field of vehicle engineering. Background technique [0002] With people's continuous pursuit of vehicle performance, amphibious vehicles are becoming more and more important in the military, and civilian vehicles are also actively involved in the amphibious vehicle market. Amphibious vehicles have become the latest hot spot in the automotive industry. The research on amphibious vehicles in foreign countries started earlier, with a solid foundation and advanced core technologies. Although the research on amphibious vehicles in my country started late, it developed rapidly. [0003] The electric cylinder is an easy-to-purchase power component. The internal structure includes a motor, a reduction mechanism, a screw, a nut, and a power-off switch at a limit position. The telescopic movement of the electric cylinder is co...

AI Technical Summary

Problems solved by technology

The wheels of ordinary amphibious vehicles fall on the outside of the vehicle body when driving in the water, which affects the streamlined part of the vehicle in the water and greatly increases the driving resistance of the vehicle in the water
