Abstract
The utility model discloses a special high pressure heave load quick lift air bag for an automobile chassis dynamometer, which comprises a rubber air bag with openings at both ends, an upper cover plate and an upper base plate which are in seal and fixed connection with the rubber air bag are arranged at the upper opening, an lower cover plate and a lower base plate which are in seal and fixed connection with the rubber air bag are arranged at the lower opening; the lower cover plate is provided with an air inlet and a waist hoop is arranged in the middle along the lifting direction of the outer wall of the rubber air bag, which makes the rubber air bag assume a butterfly-shaped structure with two ends bigger than the middle. The utility model has the technical advantages that because the rubber air bag is made into a butterfly-shaped structure with two ends bigger than the middle via the waist hoop and thus the air bag can lift rapidly even under a high pressure and heavy load state.
Description
Technical field
The utility model relates to a kind of road simulation dynamometer, relates in particular to the special-purpose lifting gasbag of a kind of road simulation dynamometer.
Background technology
At present, lifting gasbag generally is used for heavy type (the heavy 15t of axle) road simulation dynamometer lifting beam lifting, conveniently to be examined vehicle turnover dynamometer machine stand.Road simulation dynamometer has following requirement to lifting gasbag: enough big lifting force should be arranged; The lifting stroke is greater than 110mm; The lifting beam rises and was less than fall time 5 seconds.There is following difficulty in the requirement that reaches high pressure heavy load fast lifting: lifting gasbag limits because of being subjected to spatial volume between the major-minor cylinder, can not be by the augmented airbag diameter to improve lifting force; If improve lifting force by increasing gas pressure means, it is withstand voltage to improve air bag to increase the air bag wall thickness, causes the air bag screen resilience to increase so again, makes that the lifting beam rises, decline rate is slack-off, can not satisfy decline rate requirement in 5 seconds.The lifting gasbag of prior art comprises the rubber pneumatic bag of both ends open, be provided with upper cover plate and the upper plate that is sealedly and fixedly connected with rubber pneumatic bag in upper shed place, be provided with lower cover and the lower shoe that is sealedly and fixedly connected with rubber pneumatic bag under shed, on lower shoe, be provided with air admission hole.The lifting gasbag of prior art does not reach the requirement of high pressure heavy load fast lifting.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of special-purpose lifting gasbag of road simulation dynamometer of high pressure heavy load fast lifting is provided.
The technical scheme that the utility model adopted is: road simulation dynamometer special high-pressure heavy load fast lifting air bag, the rubber pneumatic bag that comprises both ends open, be provided with upper cover plate and the upper plate that is sealedly and fixedly connected with rubber pneumatic bag in upper shed place, be provided with lower cover and the lower shoe that is sealedly and fixedly connected with rubber pneumatic bag under shed, on lower shoe, be provided with air admission hole, outer wall at rubber pneumatic bag is located to be provided with the waist hoop in the middle of the lifting direction, makes rubber pneumatic bag form the little butterfly structure in big centre, two.
The utility model beneficial technical effects is: because rubber pneumatic bag makes the little butterfly structure in big centre, two with the waist hoop, make it can also fast lifting under the situation of high pressure heavy load.
Description of drawings
Fig. 1: be structural representation of the present utility model;
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in the figure, road simulation dynamometer special high-pressure heavy load fast lifting air bag, the rubber pneumatic bag 1 that comprises both ends open, be provided with upper cover plate 2 and the upper plate 3 that is sealedly and fixedly connected with rubber pneumatic bag 1 in upper shed place, be provided with lower cover 4 and the lower shoe 5 that is sealedly and fixedly connected with rubber pneumatic bag 1 under shed, on lower shoe 5, be provided with air admission hole 6, outer wall at rubber pneumatic bag 1 locates to be provided with waist hoop 7 in the middle of the lifting direction, make rubber pneumatic bag 1 form the little butterfly structure in big centre, two, promptly two is dolioform.As further improvement, waist hoop 7 is with the annulus of the global formation of weldless steel tube car system or forging, has the good non-damageable advantage of intensity, establishes rubber at the outer bread of waist hoop 7, and its damage and wearing and tearing to rubber pneumatic bag 1 are reduced to a minimum.The structure of rubber pneumatic bag 1 wall thickness xsect is that inside and outside wall is a rubber, and the centre is soft cord 8, makes the load-bearing capacity of rubber pneumatic bag 1 and intensity better.In addition, it is bigger that the area of upper cover plate 2 and lower cover 4 is done, and under the situation of identical pressure, has bigger lifting force.
