Abstract
The utility model discloses a chassis air spring, which is characterized in that the bottom end of a capsule is pressed with the side wall of a piston; the upper end of the capsule is fastened with an upper cover plate; one end of the upper cover plate is respectively provided with an air pipe joint and a locating pin; the air pipe joint is hollow and is communicated with the inside of the capsule; the middle of the lower end of the upper cover plate is provided with a bulge which is connected with an emergency stop catch; the whole piston is made of metal material and is in an integral structure; and the bottom end of the piston is further provided with a bolt hole. With the device, the utility model improves the damping effect and consequently meets the requirements of light-weighted technology and comfort of the prior vehicle. The utility model is applicable to various complex road conditions of the vehicles.
Description
Technical field
The utility model relates to a kind of novel commercial car shock absorber component, definite a kind of air spring assembly that is applied to chassis suspension fork of vehicle of saying so.
Background technique
Commercial car chassis suspension system uses leaf spring to carry out vibration damping more at present, because leaf spring natural frequency height, vehicle is when overturning road traveling, effectiveness in vibration suppression difference and working life are short, the weight of leaf spring on the other hand can not satisfy the trend of current vehicle technology lightweight, comfortableization development.
Summary of the invention
, shortcoming such as working life short and weight big poor for natural frequency height, the effectiveness in vibration suppression of improving current leaf spring, the utility model is satisfying under the prerequisite of original performance, and its structure and material thereof are improved.
Concrete technological scheme is: be fitted together in the bottom of capsule and the side wall and pressure of piston, the upper end of capsule is withheld with upper cover plate and is connected, end at upper cover plate is respectively equipped with a gas-tpe fitting and locating stud, gas-tpe fitting is hollow and is communicated with capsule, center bottom at upper cover plate is provided with a projection, emergent backstop projection therewith connects, and whole piston is metallic material and integral type structure, also is provided with a bolt hole in the bottom of piston.
The utility model makes the gas seal of column in capsule by upper press cover and piston, formed the locking system of air spring assembly, air spring assembly feeds pressurized air in the locking system when work, form fixed system, air spring assembly utilizes pressurized gas as Elastic medium; For fixed system, when load increased, volume of air reduced, and it is big that spring constant becomes.On the contrary, when load reduced, gas expanded, and volume increases, and spring constant reduces.Therefore, used the suspension system natural frequency of air spring assembly to change, improved the high shortcoming of natural frequency of leaf spring, improved the effectiveness in vibration suppression of air spring assembly along with the variation of load; In addition, the capsule halves of air spring assembly is rubber folder fabric layer structure, and is more in light weight than original Steel Spring Plate, improved effectiveness in vibration suppression simultaneously again, and then satisfied the requirement of current vehicle technology lightweight, comfortableization, can satisfy the requirement of vehicle driving in various complex road conditions.

Embodiment
As shown in Figure 1, the side wall and pressure of the bottom of capsule 5 and piston 6 is fitted together, the upper end of capsule 5 is withheld with upper cover plate 3 and is connected, end at upper cover plate 3 is respectively equipped with a gas-tpe fitting 1 and locating stud 2, gas-tpe fitting 1 be hollow and with capsule 5 internal communication, be provided with a projection in the center bottom of upper cover plate 3, emergent backstop 4 projection therewith connects, whole piston 6 is metallic material and integral type structure, also is provided with a bolt hole in the bottom of piston 6.Gas-tpe fitting 1 is mainly used in the connection gas piping; Locating stud 2 main effects are installing and locating, and upper cover plate 3 is used for the effect of sealing gas and installation; Emergent backstop 4 main effects are the backstop of meeting an urgent need under unexpected situation; Capsule 5 is an elastic element, plays buffering vibration, and piston 6 plays sealing, supports and is connected.
