Description
Technical field
The utility model relates to a kind of vehicle height control valve, particularly relates to a kind of for the vehicle height control valve in the vehicle suspension system with air bellow (air bag).
Background technology
In prior art, due to the change of bodywork height in AIRMATIC Dual Control, drive levelling valve adjustable connecting-rod up-and-down movement, the spool control stalk that adjustable link position change promotes levelling valve rotates, and realizes air bellow air inlet, the function of protecting gas and exhaust.Due to the accuracy of manufacture of bodywork parts and the impact of suspension welding precision, after causing the installation of conventional height valve, there is certain difference in real balance position and the Theoretical Equilibrium height of air bellow, if difference is too large, can produce harmful effect to the attitude of vehicle body and stability.Therefore, need the adjustable connecting-rod of professional's Manual height valve to make vehicle body reach balance to compensate manufacturing errors, but this control process not only bothers, and waste time and energy, if number of vehicles is many, the work capacity of professional will increase greatly.
Summary of the invention
The purpose of this utility model is, there is provided a kind of by air inlet, the three groups of actions protecting gas and exhaust, to regulate the vehicle height control valve of air spring height, eliminate after levelling valve is installed and need professional to the adjustment process of height regulating rod, to overcome prior art deficiency.
The technical solution of the utility model: a kind of vehicle height control valve, comprise valve body and spool, spool can slide in valve body, gap is provided with between the inwall of valve body and the outer wall of spool, the oral area of valve body keeps being sealed and matched by the outer wall of seal ring and spool, the sidewall of valve body upper end is provided with the admission port be communicated with body cavity, the sidewall of spool lower end is provided with the air extractor duct be communicated with valve core cavity, the through hole that level runs through valve core cavity is provided with in the upper end of air extractor duct, upper binding head is fixedly connected with in the upper end of valve body, lower union joint is fixedly connected with in spool lower end.
The upper end of spool is provided with counterbore, the boss bearing fit in this counterbore and valve body.
The oral area of valve body being provided with dust ring, for wiping the foreign material that spool is stained with off, ensureing the service life of seal ring and the fluency of valve core movement.
Rubber or polyurethane is provided with in described upper binding head and the torsion sleeve of lower union joint.
Described upper binding head is fixedly connected on by thread rod on the boss in valve body.
Owing to adopting technique scheme, the utility model has the advantage of: when the utility model being used for the vehicle suspension system with air bellow, admission port on valve body is communicated with external air source, by entering of the air extractor duct on spool and air bellow, deflation hole is communicated with, thus realize air bellow inflation by the change of lead to the hole site on spool, protect the function of gas and exhaust, namely when the height of suspension changes, by the linear reciprocating motion of spool in valve body, when valve core movement is to body cavity, air bellow is communicated with admission port by levelling valve, realize air inlet, when valve core movement is to meta, air bellow neither air inlet is not vented yet and is in state of equilibrium, when the through hole on spool moves to valve body outside, air bellow gas circuit is exhausted by spool.Therefore, the utility model not only structure is simple, reasonable in design, time saving and energy saving, and instead of prior art manually regulating valve stem length to realize air bellow air inlet, protect gas and degassing function, substantially increase the installation effectiveness of levelling valve.

Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
The structural representation of vehicle height control valve as shown in Figure 1, comprise valve body 2 and spool 5, spool 5 can slide in valve body 2, gap is provided with between the inwall of valve body 2 and the outer wall of spool 5, the oral area of valve body 2 keeps being sealed and matched by the outer wall of seal ring 3 with spool 5, the sidewall of valve body 2 upper end is provided with the admission port 12 be communicated with body cavity 10, the sidewall of spool 5 lower end is provided with the air extractor duct 7 be communicated with valve core cavity 13, the through hole 9 that level runs through valve core cavity 13 is provided with in the upper end of air extractor duct 7, upper binding head 1 is fixedly connected with in the upper end of valve body 2, lower union joint 6 is fixedly connected with in spool 5 lower end.The upper end of spool 5 is provided with counterbore 8, and this counterbore 8 and boss 11 bearing fit in valve body 2, arrange the action radius that can increase spool 5 like this, and then improve the modification scope of levelling valve.The oral area of valve body 2 being provided with dust ring 4, for wiping the foreign material that spool 5 is stained with off, ensureing the service life of seal ring 3 and the fluency of spool 5 motion.Rubber is provided with in described upper binding head 1 and the torsion sleeve of lower union joint 6; Described upper binding head 1 is fixedly connected on by thread rod on the boss 11 in valve body 2.
Principle of work of the present utility model:
See Fig. 1, when the utility model being used for the vehicle suspension system with air-spring bellows, the admission port 12 on valve body 2 is communicated with external air source, the air extractor duct 7 on spool 5 is communicated with the inlet and outlet hole of air bellow.When the air pressure in air bellow reduces, therefore the height of suspension reduces, thus cause the entire length of levelling valve to reduce, namely spool 5 moves in valve body 2, when spool 5 moves to body cavity 10, by the through hole 9 on spool 5, the admission port 12 on valve body 2 is communicated with the air extractor duct 7 on spool 5, now realizes air bellow air inlet; Along with the increase of suction quantity, when spool 5 moves to meta, the through hole 9 on spool 5 is in the position of valve body 2 oral area seal ring 3, now air bellow neither air inlet be not also vented, be in state of equilibrium; When the air pressure in air bellow is too high, therefore the height of suspension raises, and make through hole 9 on spool away from the position of valve body 2 oral area seal ring 3, move to the outside of valve body 2, now air bellow gas circuit is exhausted by the through hole 9 on spool.Therefore, the utility model realizes air bellow inflation by the change of through hole on spool 9 position, protects the function of gas and exhaust.
