Embodiment Construction

[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] An embodiment of an airbag inflation and deflation system for a tag axle

[0013] like figure 1 As shown, the air bag reverse charging and discharging system of the tag axle includes two identical charging and deflation units, and each charging and deflation unit includes an air bag height control valve 1, a normally open solenoid valve 2, an overflow valve 3, a follow-up Bridge air bag 4, middle bridge air bag 5 and height control valve intake pipeline 6. The air intake line 6 of the height control valve is connected to port 1 (intake port) of the airbag height control valve 1, and port 21 (air outlet) of the air bag height control valve 1 is connected to port 1 (normal port) of the normally open solenoid valve 2 , port 22 (air outlet) of the airbag height control valve 1 is connected to the air inlet of the middle bridge airbag 5,...

Abstract

The invention relates to a rear axle airbag inflating and deflating system and a three-axle vehicle using same. The system comprises an airbag height control valve, a rear axle airbag, a normally open solenoid valve and an overflowing valve; a normally open hole of the normally open solenoid valve is connected with an air outlet of the airbag height control valve, while the other normally open hole is connected with an air inlet of the rear axle airbag; a normally close hole of the normally open solenoid valve is connected with an air inlet of the overflowing valve, and a control interface of the normally open solenoid valve is connected with a reverse gear signal circuit of the three-axle vehicle; and the normally open solenoid valve is controlled to be opened or closed to realize the function of automatically inflating and deflating the rear axle airbag according to a reverse gear signal. The rear axle airbag inflating and deflating system is simple to realize and low in cost, and the three-axle vehicle using the system can reduce the rear axle load without changing the existing suspension structure thereof in the braking process, thereby reducing abrasion of the rear axle tire.

Description

technical field [0001] The invention relates to an air bag inflation and deflation system of a traveling axle and a three-axle vehicle using the system. Background technique [0002] For the three-axle vehicle installed with air suspension, the air bag inflation and deflation system of the tag axle includes: height control valve, air bag of tag tag, mid-bridge air bag and air intake pipeline of height control valve, air inlet of air bag height control valve It is connected with the air intake pipeline of the height valve, and the two air outlets of the height control valve are respectively connected with the air inlet of the middle bridge airbag and the air inlet of the follower axle airbag. Because the turning radius of the trailing axle of the three-axle vehicle does not match the turning radius of the front two axles, when the three-axle vehicle using this kind of trailing axle airbag inflation and deflation system reverses, the friction between the trailing axle tires an...
