Abstract

The invention discloses an oil-pneumatic spring rear suspension system for mining vehicles, which includes a vehicle frame and a suspension mechanism installed on the vehicle axle. The suspension mechanism is installed on the vehicle frame. The suspension mechanism includes four oil-pneumatic springs and two high and low pressure springs Accumulator and a set of guide mechanism; four oil-pneumatic springs are respectively arranged at the two ends of the lower middle and rear axles. Vertical load, the oil and gas springs on the middle and rear axles are interconnected through oil pipes to realize the function of balanced suspension; the guide mechanism is installed inside the frame, and the invention solves the problem of poor carrying capacity and poor comfort of the vehicle in the prior art, and the vehicle Technical problems with short service life.

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....
