Abstract
The utility model discloses a double -piston rubber air spring, including pneumatic rubber capsules, the fixed upper end cover that is provided with in pneumatic rubber capsules's upper end, pneumatic rubber capsules's lower extreme is fixed and is provided with the bottom end cover, fixes being provided with the suction nozzle on the bottom end cover, is provided with the air inlet that is linked together with pneumatic rubber capsules on the suction nozzle, and characteristics are that the fixed cover in pneumatic rubber capsules's upper end is equipped with the upper piston, and pneumatic rubber capsules's lower end fixing cover is equipped with the lower piston, upper piston and automobile frame fixed connection, lower piston and automobile axle fixed connection, the advantage is equipped with upper and lower piston because the cover is do not fixed to pneumatic rubber capsules's upper and lower tip, and when the rubber air spring compressed, pneumatic rubber capsules's upper and lower both ends are compress simultaneously for upper and lower stroke when gasbag compressed and release is short, has lengthened the life of gasbag, thereby also makes whole rubber air spring's life long.
Description
Technical field
The utility model relates to the elastic member in vehicle air suspension system, particularly relates to a kind of double-piston rubber air spring.
Background technique
Vehicle air suspension system mainly makes the intercropping elasticity of vehicle frame and vehicle bridge contact, and bears and transmits normal load, relaxes and resists the impact caused by uneven road surface.And rubber air spring is the primary resilient element in vehicle air suspension system, it is filled with pressurized air in flexible encapsulated container, utilizes the compressibility of air to realize the nonmetal spring of one of elastic reaction.The Long travel rubber air spring used in current vehicle air suspension system, when compressing, the stroke of air bag is long, causes the working life of such rubber air spring short.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of double-piston rubber air spring increased the service life.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of double-piston rubber air spring, comprise rubber pneumatic bag, the upper end of described rubber pneumatic bag is fixedly installed upper end cap, the lower end of described rubber pneumatic bag is fixedly installed lower end cap, described lower end cap is fixedly installed air inlet nozzle, described air inlet nozzle is provided with the suction port be connected with described rubber pneumatic bag, the upper end portion fixed cover of described rubber pneumatic bag is provided with upper piston, the underpart fixed cover of described rubber pneumatic bag is provided with lower piston, described upper piston is fixedly connected with automobile frame, described lower piston is fixedly connected with automotive axle.
Described upper end cap is fixedly installed connecting bolt, described upper piston is set in the upper end portion of described rubber pneumatic bag, described connecting bolt is upward through described upper piston, described connecting bolt is bolted with upper cap nut and is fixed by described upper piston by described upper cap nut.
Described lower piston is set in the underpart of described rubber pneumatic bag, and described air inlet nozzle is passed down through described lower piston, described air inlet nozzle is bolted with lower nut and is fixed by described lower piston by described lower nut.
Described rubber pneumatic bag small in ends up and down, broad in the middle.
Described upper end cap and described lower end cap are fixed with the end integrated vulcanizing of the rubber pneumatic bag described in its corresponding end respectively, can play sealing supporting effect.
Described rubber pneumatic bag forms by three layers, and skin is the ageing-resistant rubber cover of oil resistant, and centre is the cord framework layer of high strength, and internal layer is the rubber layer that tightness is good.
Compared with prior art, the utility model has the advantages that due to rubber pneumatic bag upper and lower end portion respectively fixed cover be provided with upper and lower piston, when the rubber air spring of Long travel is compressed, the two ends up and down of rubber pneumatic bag can be compressed simultaneously, stroke up and down when making air bag be compressed and discharge is short, extend the working life of air bag, thus also make the long service life of whole rubber air spring; And structure is simple, easy to assembly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model when being compressed;
Fig. 2 is the structural representation after the utility model removes upper and lower piston.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in the figure, a kind of double-piston rubber air spring, comprise rubber pneumatic bag 1, rubber pneumatic bag 1 small in ends up and down, broad in the middle, the upper end integrated vulcanizing of rubber pneumatic bag 1 is fixed with upper end cap 2, the upper end portion of rubber pneumatic bag 1 is arranged with upper piston 3, upper end cap 2 is fixedly installed connecting bolt 4, connecting bolt 4 is upward through upper piston 3, connecting bolt 4 be bolted with upper cap nut 41 and by upper cap nut 41, upper piston 3 fixed, the lower end integrated vulcanizing of rubber pneumatic bag 1 is fixed with lower end cap 5, lower end cap 5 is fixedly installed air inlet nozzle 6, air inlet nozzle 6 is provided with the suction port 61 be connected with rubber pneumatic bag 1, the underpart of rubber pneumatic bag 1 is arranged with lower piston 7, air inlet nozzle 6 is passed down through lower piston 7, air inlet nozzle 6 be bolted with lower nut 8 and by lower nut 8, lower piston 7 fixed, upper piston 3 is fixedly connected with automobile frame (not shown), lower piston 7 is fixedly connected with automotive axle (not shown).
In above-described embodiment, rubber pneumatic bag 1 forms by three layers, and skin is the ageing-resistant rubber cover of oil resistant, and centre is the cord framework layer of high strength, and internal layer is the rubber layer that tightness is good.
