Abstract
The utility model discloses a sleeve-type rubber air spring, which comprises a tubular airbag. An upper cover plate is fixedly inserted in the upper end opening of the tubular airbag. An inlet for filling air in the tubular airbag is arranged on the upper cover plate; a plunger is fixedly inserted in the lower end opening of the tubular airbag. A fixed screw hole fixedly connected with a carriage is arranged on the plunger. In this way, a damping system consisting of the tubular airbag which compressed air can be filled in and the plunger is adopted to achieve flexible damping effect, which is effective in damping, improves the comfort of drivers during vibration, prevents a metal spring from colliding with the carriage and being damaged in case of high vibration, improves the service life of the damping system, reduces the damage of automobiles to the road, and relieves the fatigue of drivers. Accordingly, the utility model provides the sleeve-type rubber air spring which can damp vibration well, is very comfortable with long performance life, which is used for the damping system of an automobile cab.
Description
Technical field
The utility model relates to air bellow, is specifically related to a kind of telescoping rubber air spring.
Background technology
The vibration insulating system of automobile cab mainly is to make between vehicle frame and the operator's compartment to get in touch as elasticity, bears and transmit vertical load, relaxes and the caused impact of resistance uneven road surface.The vibration insulating system of traditional automobile cab adopts steel spring or wire spring usually, though can reach effectiveness in vibration suppression, effectiveness in vibration suppression is undesirable, the chaufeur comfort level is relatively poor, and easily cause the damage of metal spring damage and vehicle body on the road surface of jolting, reduce its service life.Rubber pneumatic bag has been widely used in making in the air bellow as soft elastomeric material, as China Patent No. is 01272547.1, name is called the utility model patent of suspension-type automobile rubber air bellow, disclose the air bellow of rubber barrel-like structure, the bucket wall is equipped with the buffering blob of viscose by outer glue-line, inner glue layer and inside, is respectively fitted with the air bellow of upper and lower cover plate up and down at the bucket wall.
Summary of the invention
It is good that technical problem to be solved in the utility model provides a kind of cushioning performance, comfort level height, the telescoping rubber air spring of the vibration insulating system that is used for automobile cab of long service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of telescoping rubber air spring, comprise the tubulose air bag, upper port at described tubulose air bag fixedly is plugged with upper cover plate, described upper cover plate is provided with gas filed induction opening in described tubulose air bag, lower port at described tubulose air bag fixedly is plugged with piston, and described piston is provided with the fixing threaded hole of captiveing joint with vehicle frame.
Be outside equipped with clamping ring in the upper port of described tubulose air bag.
Lower port at described tubulose air bag is outside equipped with clamping ring down.
Above-mentioned tubulose air bag is divided into three layers, and skin is the ageing-resistant rubber cover of oil resistant, and the middle level is high-intensity cord casing play, and internal layer is the good rubber layer of air-tightness.
Compared with prior art, advantage of the present utility model is fixedly to be plugged with upper cover plate in the upper port of tubulose air bag, upper cover plate is provided with gas filed induction opening in described tubulose air bag, lower port at the tubulose air bag fixedly is plugged with piston, piston is provided with the fixing threaded hole of captiveing joint with vehicle frame, realized the damping of vibrations of flexibility like this with the vibration insulating system that can fill compressed-air actuated tubulose air bag and piston composition, has the better damping effect, improved the comfort level of chaufeur when vibration, prevented when bigger vibration metal spring and the vehicle frame collision phenomenon that is damaged, improved the service life of vibration insulating system, reduce the infringement of automobile road pavement simultaneously, alleviated the driver fatigue sense; Therefore the utility model is that a kind of cushioning performance is good, comfort level height, the telescoping rubber air spring of the vibration insulating system that is used for automobile cab of long service life.Last clamping ring and following clamping ring are fixedly to peg graft more firmly, prevent that bigger vibration from causing separating of upper cover plate and piston and tubulose air bag; Strengthen the sealing property of the port of tubulose air bag simultaneously, reduced the generation of gas leak phenomenon.
