Abstract
The utility model discloses a rubber auxiliary spring for bus. A mounting hole (2) is drilled on a close end of a drum-shape auxiliary spring main body (1); at least one decompression hole (4) is provided on the sidewall of the auxiliary spring main body (1); a cavity (3) of the auxiliary spring main body (1) is connected with the outside through the decompression hole (4). The utility model can ensure that, the cavity of the auxiliary spring main body is always communicated with the outside via the decompression hole, which can effectively eliminate fatigue damage on the sidewall because of high pressure in the cavity when the auxiliary spring works, so that service life of the rubber auxiliary spring can be guaranteed. The utility model has the advantages of simple structure, easy execution and is suitable for large-scale expansion and application.
Description
Technical field
The utility model relates to a kind of passenger vehicle parts, especially passenger vehicle rubber auxiliary spring.
Background technique
At present, general passenger vehicle rubber auxiliary spring is a tubular structure.Closed end at the auxiliary spring body has mounting hole, and bolt passes this mounting hole from the bottom up the auxiliary spring body is fixed on the auxiliary spring bracket of vehicle frame side, and the open-mouth end of auxiliary spring body is unsettled.Travel on the road surface of passenger vehicle at hollow, when the spring amplitude was big, back axle was upwards jumped, and the steel plate on the back axle upwards pushes the rubber auxiliary spring, and this moment, the rubber auxiliary spring played cushioning effect.But the inner chamber open-mouth of rubber auxiliary spring is sealed by steel plate, the air pressure in the inner chamber is increased, and outwards push the sidewall of auxiliary spring body, makes sidewall constantly frequent flexible, easily causes its fatigue damage.Particularly under the weather conditions condition of severe, the weakness of rubber auxiliary spring sidewall is easier to break because of fatigue damage, makes can not get ensureing the working life of rubber auxiliary spring.
The model utility content
For solving above technical problem, the purpose of this utility model is to provide a kind of can effectively eliminate the passenger vehicle rubber auxiliary spring that fatigue damage takes place greatly because of chamber pressure.
The technical solution of the utility model is as follows: a kind of passenger vehicle rubber auxiliary spring, closed end at tubular auxiliary spring body has mounting hole, its key in: the sidewall of described auxiliary spring body is provided with at least one vent, and the inner chamber of auxiliary spring body communicates with the external world by this vent.
When passenger vehicle travels on uneven road surface, when the rubber auxiliary spring plays cushioning effect, vent can guarantee that the chamber pressure of auxiliary spring body equates with ambient pressure all the time, thereby has eliminated because of chamber pressure makes sidewall generation fatigue damage greatly, has prolonged the working life of rubber auxiliary spring.
The inner chamber of above-mentioned auxiliary spring body has two cydariform sections from top to bottom, respectively opens a vent at the middle part of two cydariform sections, and these two vent separations are at the opposite side of auxiliary spring body.
The center line of above-mentioned vent is vertical mutually with the shaft axis of auxiliary spring body.
Because the inner chamber of auxiliary spring body has two cydariform sections, the wall thickness of two cydariform section center is less, therefore vent is located at the middle part of cydariform section, can better protect the weakness of auxiliary spring chamber body sidewall, prevented that it from breaking because of fatigue damage, the working life of rubber auxiliary spring is secure; Two vents are lived apart at the opposite side of auxiliary spring body, more help exhaust.
Beneficial effect: the utility model can guarantee that by vent the inner chamber of auxiliary spring body is in communication with the outside all the time, make sidewall generation fatigue damage greatly because of chamber pressure when effectively having eliminated auxiliary spring work, ensured the working life of rubber auxiliary spring, it has advantages such as simple in structure, that enforcement is easy, is suitable for large-scale promotion application.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, auxiliary spring body 1 is tubular, and its closed end has mounting hole 2, and bolt passes this mounting hole 2 from the bottom up auxiliary spring body 1 is fixed on the auxiliary spring bracket of vehicle frame side during installation.The inner chamber 3 of auxiliary spring body 1 is made up of two cydariform sections and a straight section from top to bottom, respectively opens a vent 4 on the wall at two cydariform sections middle part, and these two vents, 4 separations are at the opposite side of auxiliary spring body 1.The inner chamber 3 of auxiliary spring body 1 communicates with the external world by this vent 4.The center line of described vent 4 is vertical mutually with the shaft axis of auxiliary spring body 1.
Claims (3)
1, a kind of passenger vehicle rubber auxiliary spring, closed end at tubular auxiliary spring body (1) has mounting hole (2), it is characterized in that: the sidewall of described auxiliary spring body (1) is provided with at least one vent (4), and the inner chamber (3) of auxiliary spring body (1) communicates with the external world by this vent (4).
2, passenger vehicle rubber auxiliary spring according to claim 1, it is characterized in that: the inner chamber (3) of auxiliary spring body (1) has two cydariform sections from top to bottom, respectively open a vent (4) at the middle part of two cydariform sections, and this two vents (4) separation is at the opposite side of auxiliary spring body (1).
3, passenger vehicle rubber auxiliary spring according to claim 1 and 2, it is characterized in that: the center line of described vent (4) is vertical mutually with the shaft axis of auxiliary spring body (1).
