Embodiment Construction

[0035] Embodiments of the present invention are described by taking a 4-wheel amphibious vehicle as an example.

[0036] Such as figure 1 As shown, the retractable oil-pneumatic suspension system of a wheeled amphibious vehicle includes a hydraulic power module, a front left suspension oil-pneumatic spring module, a front right suspension oil-pneumatic spring module, a rear left suspension oil-pneumatic spring module, and a rear right suspension oil-pneumatic spring module module. Among them, the structure and composition of the four suspension oil-pneumatic spring modules are completely consistent. The following is an example of the front right suspension oil-pneumatic spring module, which includes a working cylinder, an accumulator, the first damping valve assembly, the second Damper valve assembly and solenoid valve group.

[0037] Such as figure 1 As shown in , the hydraulic power module provides hydraulic energy for each suspension oil-pneumatic spring module.

Abstract

The invention discloses a wheel-type amphibious vehicle retractable type oil gas suspension system and a control method of the system. Except for achieving of buffer vibration damping function, the double-direction driving motion is achieved, and wheel retractable functions and vehicle body height adjusting functions are achieved. According to the system, a hydraulic power module is connected to suspension oil gas spring modules through an oil supply channel and an oil returning channel; the hydraulic power module provides hydraulic energy for the suspension oil gas spring modules; each suspension oil gas spring module comprises a working oil cylinder, an energy accumulator, a first damping valve assembly, a second damping valve assembly and an electromagnetic valve set; an upper lug ring of each working oil cylinder is connected with the vehicle body; a lower lug ring of each working oil cylinder is connected to a suspension lower cross arm lug ring support; the first damping valve assemblies are arranged between rodless cavities of the working oil cylinders and the energy accumulators; the second damping valve assemblies are arranged between rod cavities and the rodless cavities of the working oil cylinders; and the electromagnetic valve sets are used for controlling oil liquid for enabling the hydraulic power module to enter and go out of the rod cavities and the rodless cavities of the working oil cylinders and whether the rod cavities and the rodless cavities of the working oil cylinders are communicated or not.

Description

technical field [0001] The invention relates to a vehicle suspension system, in particular to a suspension system for a wheeled amphibious vehicle, which belongs to the field of vehicle engineering. Background technique [0002] Wheeled amphibious vehicles are widely used in military and civilian transportation, emergency rescue and disaster relief, and leisure and entertainment because of their strong mobility in areas where rivers, ditches, and lakes and ponds are densely covered with water networks. [0003] At present, the speed of amphibious vehicles on water is mostly about 10 km / h. An important reason affecting the speed of amphibious vehicles on water is that the wheels immersed in water produce greater navigation resistance. If the wheels of the amphibious vehicle can be lifted up when navigating on water, it can reduce sailing resistance and thus increase speed. [0004] The wheels of the wheeled amphibious vehicle are connected with the vehicle body through a su...
