Abstract
The utility model discloses a kind of air spring system of external auxiliary chamber, comprise pneumatic spring, pneumatic spring upper-end surface is provided with dunnage, pneumatic spring lower end surface is provided with lower cover plate, lower cover plate is communicated by throttle orifice with the upper cover plate of auxiliary chamber, and upper cover plate is made up of regulator plate and fixed plate, is connected between regulator plate and fixed plate by screw, fixed plate is fixed on auxiliary chamber, and pneumatic spring side is connected with air compressor.The utility model, by pneumatic spring outer installment auxiliary chamber, serves the effect of vibration damping well.
Description
Technical field
The utility model relates to a kind of air spring system, especially a kind of air spring system of external auxiliary chamber.
Background technique
Along with the fast development of Domestic Automotive Industry and improving constantly of people's living standard, and the intensification gradually that heavy-duty car is familiar with the road damage origin cause of formation, be all strongly required improve vehicle performance and strengthen road transportation management P.Reduce automobile to the destruction of road, improve the road friendliness of vehicle, improve smoothness when vehicle travels and riding comfort simultaneously, vehicle mounting air spring suspension systems is a kind of approach preferably.
Air spring suspension systems has the characteristic of variation rigidity, low vibration frequency, anti-road shocks, effectively can improve the run smoothness of vehicle, riding comfort and control stability, also can reduce the performances such as the destruction of vehicle road pavement.And air spring system is the critical component of air spring suspension systems, be a kind of novel vibration isolation elastic system, the requirement improving vehicle suspension system performance can be met.At present, air spring for automobile often adopts bellow type air spring or diaphragm typeair spring, during use, although improve stationarity when car travels to a certain extent, but run into some emergency case or comparatively jolt road surface time, the natural frequency of vibration of pneumatic spring can be very high, can not play the effect of vibration damping well, and the swept volume of pneumatic spring is limited, surge pressure can be very large.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of air spring system of external auxiliary chamber, can play the effect of vibration damping well.
For achieving the above object, the technical solution of the utility model is: a kind of air spring system of external auxiliary chamber, comprise pneumatic spring, pneumatic spring upper-end surface is provided with dunnage, and pneumatic spring lower end surface is provided with lower cover plate, and lower cover plate is communicated by throttle orifice with the upper cover plate of auxiliary chamber, upper cover plate is made up of regulator plate and fixed plate, be connected by screw between regulator plate and fixed plate, fixed plate is fixed on auxiliary chamber, and pneumatic spring side is connected with air compressor.
As the further setting of such scheme, the aperture of the upper and lower two-port of throttle orifice is equal and be greater than aperture, middle.
The beneficial effects of the utility model are: the setting of auxiliary chamber, increase the gas gross of pneumatic spring, have impact on the vibration characteristics of pneumatic spring; Throttle orifice limits the flowing velocity of gas, gas flow through throttle orifice time produce damping function, play the effect of attenuation vibration.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: pneumatic spring 1, dunnage 2, lower cover plate 3, auxiliary chamber 4, upper cover plate 5, regulator plate 51, fixed plate 52, throttle orifice 6, screw 7, air compressor 8.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of air spring system of external auxiliary chamber, comprise pneumatic spring 1, pneumatic spring 1 upper-end surface is provided with dunnage 2, and pneumatic spring 1 lower end surface is provided with lower cover plate 3, and lower cover plate 3 is communicated by throttle orifice 6 with the upper cover plate 5 of auxiliary chamber 4, upper cover plate 5 is made up of regulator plate 51 and fixed plate 52, be connected by screw 7 between regulator plate 51 and fixed plate 52, fixed plate 52 is fixed on auxiliary chamber 4, and pneumatic spring 1 side is connected with air compressor 8.
The aperture of throttle orifice about 6 two-port is equal and be greater than aperture, middle.
Working principle of the present utility model is: dunnage 2 is when being subject to applied external force, pneumatic spring 1 produces deformation compression or stretches, between pneumatic spring 1 and auxiliary chamber 4, gas produces pressure difference, and under the effect of pressure difference, gas can back and forth flow, and produces gas exchanges.The existence of auxiliary chamber 4, increases pneumatic spring 1 internal gas total amount and working space, have impact on the vibration characteristics of pneumatic spring 1.Throttle orifice 6 limits the flowing velocity of gas, gas flow through throttle orifice 6 time produce damping function, play the effect of attenuation vibration.The speed of gas flow when throttle orifice 6 reaches, when changing regulator plate 51, as long as turn on screw 7 by changing regulator plate 51.The wherein setting of air compressor 8, inflates to pneumatic spring 1 to facilitate.
Claims (2)
1. the air spring system of an external auxiliary chamber, comprise pneumatic spring (1), described pneumatic spring (1) upper-end surface is provided with dunnage (2), it is characterized in that: described pneumatic spring (1) lower end surface is provided with lower cover plate (3), described lower cover plate (3) is communicated by throttle orifice (6) with the upper cover plate (5) of auxiliary chamber (4), described upper cover plate (5) is made up of regulator plate (51) and fixed plate (52), be connected by screw (7) between described regulator plate (51) and fixed plate (52), described fixed plate (52) is fixed on auxiliary chamber (4), described pneumatic spring (1) side is connected with air compressor (8).
2. the air spring system of a kind of external auxiliary chamber as claimed in claim 1, is characterized in that: the aperture of the upper and lower two-port of described throttle orifice (6) is equal and be greater than aperture, middle.
