Abstract

The invention discloses a mining vehicle hydro-pneumatic spring rear suspension system. The mining vehicle hydro-pneumatic spring rear suspension system comprises a vehicle frame and a suspension mechanism mounted on a vehicle axle. The suspension mechanism is mounted on the vehicle frame and comprises four hydro-pneumatic springs, two high-low pressure energy accumulators and a guiding mechanism.The four hydro-pneumatic springs are arranged at the two ends of an intermediate axle and a rear axle correspondingly and connected with the high-low pressure energy accumulators through oil pipes. Variation of the empty load and the full load is achieved through variation of the oil pressure; the hydro-pneumatic springs bear the vertical load; the hydro-pneumatic springs on the intermediate axleand the rear axle are inter-linked through oil pipes, and the function that a suspension is balanced is achieved; a guiding mechanism is mounted in the vehicle frame; and by means of the mining vehicle hydro-pneumatic spring rear suspension system, the problems that in the prior art, a vehicle is low in bearing capacity and comfort level, and the service life of the vehicle is short are solved.

Description

technical field [0001] The invention relates to the technical field of suspension mechanisms for mining vehicles, in particular to an oil-pneumatic spring rear suspension system for mining vehicles. Background technique [0002] The existing rear suspension is a leaf spring balance suspension, and its main function is to transmit all forces and moments between the wheels and the vehicle frame (or vehicle body). And ease the impact of the car when driving on uneven roads, and attenuate the vibration of the bearing system caused by it, so as to ensure the ride comfort of the car. Among them, the vertical leaf spring is installed on the balance shaft. When the loads of the middle axle and the rear axle are inconsistent, the leaf spring rotates around the center of the balance shaft to play a role of balance compensation. The leaf spring bears the vertical load and transmits the lateral force, while the longitudinal force and moment are borne by the upper and lower thrust rods....
