Abstract

The invention relates to a steering and suspension frame adjustment composite system and an engineering vehicle, wherein the steering and suspension frame adjustment composite system comprises a steering wheel, a full-hydraulic steering gear, a steering system and a suspension system; the full-hydraulic steering gear is connected with the steering wheel in a torque transmission manner and is provided with a right-turn working oil port and a left-turn working oil port; the steering system comprises a steering wheel and a steering oil cylinder for controlling the rotating angle of the steering wheel; the suspension system comprises at least two suspension oil cylinders and at least two energy accumulators, the energy accumulators are communicated with the right-turn working oil port and the left-turn working oil port in a controllable on-off mode, and a rod cavity and a rodless cavity of each suspension oil cylinder are communicated with the two different energy accumulators respectively. According to the suspension frame adjusting system and the steering system, power oil is provided through the same full-hydraulic steering gear, sharing of a hydraulic oil source is achieved, the suspension frame adjusting system and the steering system are independent and do not interfere with each other, and thus the complexity of the hydraulic system is reduced, the use cost of a vehicle is reduced, and the failure rate is reduced.

Description

technical field [0001] The present disclosure relates to a combined steering and suspension tuning system and work vehicle. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In engineering vehicles, the steering system is usually connected between the steering wheel and the steering axle by a full hydraulic steering gear to assist the driver's steering operation. The full hydraulic steering gear drives the steering cylinder in the steering bridge through hydraulic pressure. The suspension system is supported between the car body and the frame, and is used to transmit the force and moment of the wheels and the frame, ease the impact generated by the wheels, and attenuate the vibration of the load-bearing system. [0004] For engineering vehicles, due to the heavy load and complex driving conditions, the suspension system mostly uses oil-pneumatic s...
