Abstract
The utility model relates to a self sealing type air spring bag for vehicles. The utility model comprises a short transition zone in a stop opening point, 3-5 uniformly distributed convex semi-circular sealing rings, and a layer of soft rubber layer covered on the stop opening point. The utility model has the advantages of simple structure and good manufacturability, so the general rubber adopted as the air spring of the air bag material replacing the special rubber has the higher air tightness index. So, the vehicle body declining caused by the gas leakage can be avoided, the vehicle performance can be improved, and the manufacturing quality of the air spring can be enhanced.
Description
The utility model relates to the device of a kind of vehicle with pressure self-sealing air bellow.
In the pressure self-sealing air bellow of existing vehicle, its air bag is by specific rubber and cord and is wound with one group of steel wire at stop portion and makes after sulfuration, air bag (2) is having transition region of long not uniform thickness with loam cake (1) and following the stop portion that (3) are connected, this structure leaks air air bag easily at stop portion when using the ordinary rubber material manufacture instead, cause tilting of car body, serious situation is turned round car body, influence the attractive in appearance of vehicle and prolong inflationtime, and when driving, also increase the work number of times of levelling valve, influence the vehicle in-use performance.
The purpose of this utility model is to solve above-mentioned weak point of the prior art and the air bag of the good air bellow of a kind of air-tightness of using ordinary rubber to make is provided, and when air bag is worked, the variation of shape does not influence its confined state, thereby further improve its air-tightness, avoided the work number of times of tilting of car body and minimizing levelling valve to improve the vehicle in-use performance.
The purpose of this utility model can reach by following measure: a kind of vehicle is having the transition region of a weak point with the air bag (2) of pressure self-sealing air bellow with loam cake (1), following the stop portion that (3) are connected, the projection half garden V-shaped ring (5) that to be evenly equipped with 3～5 radiuses on the surface of stop portion be R0.5～1.2mm, and on the surface of the transition region of stop portion the topped soft rubber layer (4) that one deck 1～1.5mm is arranged.
The utility model can use ordinary rubber to replace specific rubber to make air bag, keeps its air-tightness.When air bag is worked, after air bag is deformed to (2 ') by (2), do not influence the confined state of stop portion, its air-tightness of unlikely destruction, and under interior pressure effect, press tight more more.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the partial enlarged drawing of the loam cake (1) in Fig. 1 I detail drawing
Fig. 3 is the partial enlarged drawing in Fig. 1 I detail drawing
Fig. 1～Figure 3 shows that embodiment of the present utility model, air bag (2) is to use ordinary rubber (8) and cord (7) and stop portion to be wound with one group of steel wire (6) and makes after sulfuration, at the stop portion of air bag (2) length being arranged is the transition region of 16～20mm, on the conical surface of stop portion, be evenly equipped with half garden V-shaped ring (5) of two projectioies, and half garden V-shaped ring (5) of a projection is arranged on the surface of stop portion, radius R 0.8mm, the topped soft rubber layer (4) that a bed thickness 1.2mm is arranged on the surface of the transition region of the stop portion of air bag (2).
The utility model is good through trial effect, simple structure, and good manufacturability has preferably air-tightness. Adopt air spring of the present utility model to have higher air-tightness index, make through after parking 24 hours, press pressure drop to be brought up to by the original index that is not more than 20KPa in the air spring and be not more than 5KPa, improved the workmanship of air spring, thereby improved the serviceability of vehicle.
Claims (3)
1, a kind of vehicle is characterized in that air bag (2) and loam cake (1) with the air bag of pressure self-sealing air bellow, and the stop portion that following seat (3) is connected has the transition region of a weak point, is evenly equipped with half garden V-shaped ring (5) of 3～5 projectioies on the surface of stop portion.
2, a kind of vehicle according to claim 1 is characterized in that with the air bag of pressure self-sealing air bellow the radius of half garden V-shaped ring (5) of described projection is R0.5～1.2mm.
3,, it is characterized in that the topped soft rubber layer (4) that a bed thickness 1～1.5mm is arranged on the surface of transition region of stop portion of described air bag according to claim 1 and 2 described a kind of vehicles air bag with pressure self-sealing air bellows.
