Abstract

Disclosed is a pneumatic spring which comprises a cylinder body (6), a piston (5), a piston rod (3) and a guide sleeve (2); a bowl-shaped seal ring (1) is arranged in the guide sleeve (2); the pneumatic spring is characterized in that O-shaped seal rings (4) are respectively mounted on the position where the outer diameter of the guide sleeve (2) in the cylinder body (6) is contacted with the cylinder body (6), and the position where the inner hole of the guide sleeve (2) is contacted with the piston rod (3). The pneumatic spring can eliminate the oil gas leakage inside the cylinder body and prevent the outside dust and impurities from entering the cylinder body.

Description

Air spring
Technical field
The utility model relates to a kind of air spring, belongs to the auto parts machinery field.
Background technique
When present air spring cylinder body and guide sleeve sealing, only adorn a bowl ring and seal, because the mutual motion between piston rod and the guide sleeve easily produces oil, gas leakage in guide sleeve the inner.
Summary of the invention
Technical problem to be solved in the utility model is: at the problems referred to above, design and a kind ofly can reduce or eliminate oil and gas leakage and can prevent effectively that external dust from entering the air spring in the cylinder.
The technical solution of the utility model is, a kind of air spring, comprise cylinder body, piston, piston rod and guide sleeve, a bowl ring is arranged in the guide sleeve, it is characterized in that: on position that contacts with cylinder body on the guide sleeve external diameter in the cylinder body and the guide sleeve endoporus with on the position that piston rod contacts an O RunddichtringO is housed respectively.
The utility model is by respectively being equipped with an O RunddichtringO on the position that contacts with cylinder body on the guide sleeve external diameter in cylinder body and the guide sleeve endoporus with on the position that piston rod contacts, make between cylinder body and guide sleeve external diameter and piston rod and the guide sleeve endoporus and play the secondary seal effect, eliminated the leakage of oil gas in the cylinder body and can prevent that external dust impurity from entering in the cylinder body.
Through the actual tests checking, the utility model has effectively been eliminated the leakage of oil, gas in the cylinder body, and external dust can't enter in the cylinder.
Description of drawings
Accompanying drawing is an air spring structural profile schematic representation
Embodiment
A kind of embodiment of the present invention is described in conjunction with the accompanying drawings.
A kind of air spring, comprise cylinder body 6, piston 5, piston rod 3 and guide sleeve 2, a bowl ring 1 is arranged in the guide sleeve 2, it is characterized in that: on position that contacts with cylinder body 6 on guide sleeve 2 external diameters in the cylinder body 6 and guide sleeve 2 endoporus with on the position that piston rod 3 contacts an O RunddichtringO 4 is housed respectively.
