The utility model discloses the damping is effectual, and the security is high.
Description
Technical field
The utility model relates to a kind of auxiliary chamber of pneumatic spring.
Background technique
Pneumatic spring is the vitals of air spring suspension systems in vehicle mounting; significantly can weaken car vibration in the process of moving; sometimes in order to increase the gas gross of pneumatic spring; reduce the natural frequency of vibration; often can increase and auxiliary chamber is set; auxiliary chamber is generally rigid construction, and its common structure has: storage pot type, piston are portable.Wherein the existing application at present of piston movable type is more.But when Long-Time Service, such 2 problems also often can be encountered:
1, when some are had a lot of social connections comparatively badly or waviness is very large suddenly, pneumatic spring is by external influence in the process of auxiliary chamber transmitting vibrations power, and piston can be mobile rapidly, causes effectiveness in vibration suppression not to be clearly.
2, in the rapid moving process of piston, if brake not in time, be easy to collide with the cylinder cap of auxiliary chamber, cause damage.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of auxiliary chamber of pneumatic spring, good damping result, and Security is high.
For achieving the above object, the technical solution of the utility model is: a kind of auxiliary chamber of pneumatic spring, comprise cavity, cavity closed end is connected with pipeline, cavity open end is fixedly connected with cover plate by screw, inside cavity is provided with piston, seal ring is equipped with on the surface that piston contacts with cavity, piston centre place is fixedly linked by nut and piston rod, piston face is provided with the through hole centrally in a determining deviation helical pattern, snakelike through there being elongated flexible tube between often adjacent through hole, with piston rod joint, limit stoper is installed below piston, piston rod also and cover plate surface of contact is provided with seal element through cover plate, piston rod top is provided with driving mechanism connection set.
As the further setting of such scheme, number of openings is odd number.
The beneficial effects of the utility model are:
1, by a part of air pressure is flowed into elongated flexible tube, to form Yong Sai, turbulent phenomenon, produce vapour lock, reach damping function, damping vibration.
2, the setting of limit stoper, when preventing piston fast downlink and cylinder cap bump against the generation of phenomenon, improve the Security of work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of piston.
In figure: cavity 1, pipeline 2, screw 3, cover plate 4, piston 5, seal ring 6, nut 7, piston rod 8, through hole 9, elongated flexible tube 10, limit stoper 11, seal element 12, driving mechanism connection set 13.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of auxiliary chamber of pneumatic spring, comprise cavity 1, cavity 1 closed end is connected with pipeline 2, cavity 1 open end is fixedly connected with cover plate 4 by screw 3, cavity 1 inside is provided with piston 5, seal ring 6 is equipped with on the surface that piston 5 contacts with cavity 1, to ensure the sealing of piston 5 when mobile and between cavity 1, piston 5 center is fixedly linked by nut 7 and piston rod 8, piston 5 surface is provided with the through hole 9 centrally in a determining deviation helical pattern, snakelike through there being elongated flexible tube 10 between often adjacent through hole 9, with piston rod 8 joint, limit stoper 11 is installed below piston 5, piston rod 8 also and cover plate 4 surface of contact is provided with seal element 12 through cover plate 4, to ensure the sealing of piston rod 8 when moving and between cover plate 4, piston rod 8 top is provided with driving mechanism connection set 13, the drive form of driving mechanism can be hydraulic pressure or electronic or connecting rod.
Through hole 9 quantity is odd number, to ensure that two ports of elongated flexible tube 10 are respectively in the both sides on piston 5 surface.
The utility model is by shunting a part in elongated flexible tube 10 by all for script air pressure acting on piston 5 surface, because elongated flexible tube 10 snakelike coiling in the through hole 9 of piston 5, can form Yong Sai, turbulent phenomenon when air pressure passes into, produce vapour lock, reach damping function, thus reduce vibration.In addition, the setting of limit stoper 11, can prevent piston 5 at the fast speed row time and cylinder cap bump against, improve the Security of work.
