Abstract

The invention discloses a novel oil-air suspension mechanism and a vehicle, and relates to the technical field of vehicle oil-air suspensions. The novel oil-air suspension mechanism comprises two guide arms, two oil-air cylinders and an energy storage device; the two guide arms are oppositely arranged on the left side and the right side of a frame, one end of each guide arm is connected with the frame through a first support, and the middle of each guide arm is connected with an axle through a U-shaped bolt; the two oil-gas cylinders are oppositely arranged on the left and right sides of the frame, cylinder bodies of the oil-gas cylinders are connected with the frame through a second support, and piston rods of the oil-gas cylinders are hinged to the other ends of the guide arms; and the energy storage device is fixed to the frame through a third support and connected with the oil-gas cylinders.

Description

technical field [0001] The invention relates to the technical field of vehicle oil-pneumatic suspension, in particular to a novel oil-pneumatic suspension mechanism and a vehicle. Background technique [0002] GB7258-2017 stipulates that the rear axle of dangerous goods transport trucks with a total mass ≥ 12000kg, and all dangerous goods transport semi-trailers should be equipped with air suspension. With the implementation of GB7258-2017, air suspension has been widely used in recent years. Airbag air suspension has ideal variable stiffness characteristics, but it has disadvantages such as small load, large space size, and easy aging and damage. Currently, the oil-pneumatic suspension is mainly used in mining dump trucks and military vehicles. The structure of the oil-pneumatic suspension presented in the present invention is simple, and meets the load-carrying and vibration-reducing requirements of the vehicle when it is empty or fully loaded. Contents of the invention ...
