Abstract
The utility model belongs to the technical field of vehicle parts and particularly relates to a vehicle air cylinder damper. The vehicle air cylinder damper comprises a damping lower shaft sleeve, a damping spring, an air cylinder assembly and an upper shaft sleeve. The air cylinder assembly comprises a cylinder body, a piston and a piston rod, wherein the piston is arranged inside the cylinder body, one end of the piston rod is fixed on the upper shaft sleeve and the other end of the piston rod is fixedly connected with the piston, the cylinder body is fixed on the damping lower shaft sleeve, an oil filling nozzle is arranged in one side of the damping lower shaft sleeve, the oil filling nozzle is communicated with an inner cavity of the damping lower shaft sleeve, and the damping spring is fixed between the damping lower shaft sleeve and the upper shaft sleeve. According to the vehicle air cylinder damper, when the damper is shocked, abrasion caused by direct collision between the damping spring and the damping lower shaft sleeve is avoided through a limiting fixing ring arranged at the contact position between the damping lower shaft sleeve and the damping spring. After damping oil is filled into the inner cavity of the damping lower shaft sleeve through the oil filling nozzle, the piston rod and the damping oil interact when the damper is shocked, shock is resolved, and soft damping is achieved. Therefore, collision and friction between the piston and the damping lower shaft sleeve are avoided, and the service life of the piston is prolonged and the damping effect of the whole damper is improved.
Description
Technical field
The utility model belongs to the vehicle body fittings technical field, refers in particular to a kind of vehicle cylinder vibration damper.
Background technique
At present, the vehicle rear shock absorber, the cushion pad that its damping mainly relies on damping spring and piston rod top to install, be connected between piston and the Lower shaft sleeve and restore the damping spring, but piston bottom the Lower shaft sleeve inwall between no any damping device, in case the piston pressurized is bigger, can cause the violent bump in piston and Lower shaft sleeve inwall bottom, influence the whole damping effect of rear shock absorber, and rear shock absorber has influence on the working life of back damping greatly also easily because collision causes damage.Existing patented technology, be to avoid the violent bump of piston bottom the Lower shaft sleeve inwall by a buffer stopper is set in Lower shaft sleeve inwall bottom among the CN102011823A as application publication number, but the hard cushioning effect that the physical impacts of this contact reaches still can't be avoided the wearing and tearing of rear shock absorber fully.
