Amphibious vehicle turnover suspension structure and amphibious vehicle

Abstract

The invention discloses an amphibious vehicle turnover suspension structure and an amphibious vehicle. The suspension structure comprises a frame (8); wheels (1); a suspension, which is arranged between the frame (8) and the wheels (1) and comprises an upper cross arm (3), a lower cross arm (2), a rotating shaft (4), a rocker arm (5) and a hydro-pneumatic spring (7), wherein one end of the hydro-pneumatic spring (7) is connected with the rocker arm (5), and the other end of the hydro-pneumatic spring (7) is installed on the frame (8); and an angular displacement feedback mechanism. The hydro-pneumatic spring integrating the suspension elastic element function, the shock absorber function and the turnover suspension driving power source function is adopted, the hydro-pneumatic spring is transversely arranged on the vehicle left and right, the shock absorption and buffering effect of land running of the amphibious vehicle is achieved, the wheel position is lifted when wheels sail on water, the wheel lifting position is fed back through an angle displacement sensor, and the stability of the wheel lifting height is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, more specifically, to an amphibious vehicle flip suspension structure and an amphibious vehicle. Background technique [0002] The wheels of the wheeled amphibious vehicle are connected with the vehicle body through the suspension. As an important part of the vehicle, the suspension is mainly composed of shock absorbers, elastic elements, guide mechanisms and other components. smoothness and stability. In addition to driving on the road, wheeled amphibious vehicles also have good performance in water. [0003] One of the important factors affecting the speed of the wheeled amphibious vehicle on the water is that the wheels are not raised above the waterline when driving in the water, resulting in greater resistance in the water. Lifting the wheels above the waterline can reduce the resistance generated by the wheels and accessories when the vehicle is running in water, and quickly increase...

AI Technical Summary

Problems solved by technology

However, the suspension structure has the following deficiencies: (1) it adopts a link mechanism for transmission, and there are many hinge points for connection. Mechanism realization, the turning mechanism is arranged in the middle, occupying the space of the passenger compartment and the engine compartment, which is not conducive to the layout of the whole vehicle; (3) the turning structural unit and the suspension damping spring are two separate structures, which are separated from the turning power source and are not integrated , the overall structure is complex

Patent CN201520663070.5 discloses a wheel flip suspension for amphibious vehicles. The technical solution uses the torsion shaft as the flip shaft and the suspension torsion bar spring elastic element at the same time. Driving performance, but the rigidity of the turning shaft is poor, which cannot guarantee the stability of the wheel after turning over; and the longer turning shaft occupies more layout space, which is not conducive to the layout of the whole vehicle
