Problems solved by technology
[0003] As users put forward higher and higher requirements for vibration damping performance, when the road conditions are bad, the vibration of the vehicle body is much larger than that of ordinary road conditions, and long-term vibration will cause dizziness and fatigue to the driver. The air spring shock absorber on the top can only realize the adjustment of stiffness, but not the adjustment of damping, and cannot well meet the needs of users

The invention provides an air spring vibration damper, which comprises a shell and a piston cylinder. The shell comprises a first end, a second end and an elastic shell arranged between the first end and the second end, the shell is sleeved on the piston cylinder, a piston rod of the piston cylinder is fixedly connected to the first end, and a cylinder barrel of the piston cylinder is fixedly connected to the second end. The air spring vibration damper also comprises at least one damping adjusting device, each damping adjusting device comprises an auxiliary air chamber and a damping block, wherein the auxiliary air chambers are arranged on the shell; the shell is provided with auxiliary air openings; the auxiliary air chambers are communicated with an air source through the auxiliary air openings; an opening is formed in each auxiliary air chamber; the damping blocks are retractably arranged at the openings and seal the openings; and the pressure of the damping blocks to the piston rod is adjusted by adjusting the air pressure in the auxiliary air chambers, so that resistance to the piston rod is adjusted when the piston rod moves. The invention also provides a vehicle. According to the technical scheme, damping can be adjusted, and the vibration damping property of the vibration damper is optimized.
Description
technical field [0001] The invention relates to the technical field of vehicle vibration reduction, in particular to an air spring shock absorber and a vehicle. Background technique [0002] At present, the shock absorbers used in domestically produced cars and cabs are mostly hydraulic shock absorbers, and hydraulic shock absorbers are generally divided into coil spring shock absorbers and air spring shock absorbers. Among them: the coil spring shock absorber uses the elastic effect of the metal spring itself, its stiffness is a fixed value, cannot be adjusted, the vibration damping effect is poor, and its life is low, easy to fatigue and fracture, and its use is limited; while the air spring shock absorber is adjusted by adjusting The pressure value of the air changes the stiffness of the air spring, and the cab can obtain a satisfactory stiffness value no matter it is empty or fully loaded, and with the function of the height valve, the stiffness can be automatically adju...
