Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing embodiment:

[0012] figure 1 The shown air suspension alarm includes an air suspension and an air bag inside it, an air pressure sensor, a control chip, an indicator light and a buzzer. There are two airbags, namely right airbag 1A and left airbag 1B, two air pressure sensors, respectively right air pressure sensor 2A and left air pressure sensor 2B, and two indicator lights, respectively right indicator light 6A and left There are two indicator lights 6B and two buzzers, namely a right buzzer 7A and a left buzzer 7B. A right air pressure sensor 2A is installed on the right air bag 1A, a left air pressure sensor 2B is installed on the left air bag 1B, and a parking brake signal switch 3 is installed at the handbrake lever; right air pressure sensor 2A, left air pressure sensor 2B and the parking brake signal switch 3 are all electrically connected to the input end 51 of the...

Abstract

The invention discloses an air suspension alarm which comprises an air bag installed in an air suspension. The air bag is provided with an air pressure sensor which is electrically connected with an input end of a control chip of an alarm main machine arranged in a driving room; the input end of the control chip is also connected with a parking braking signal switch triggered by a manual braking mechanism; an output end of the control chip is connected with an indicating lamp and a buzzer electrically; when parking braking signals are generated, if the value of air pressure in the air bag, which is detected by the air pressure sensor, is greater than or equal to the pressure set value, the control chip simultaneously is connected with the indicating lamp and the buzzer; when the parking braking signals are not generated, if the value of air pressure in the air bag, which is detected by the air pressure sensor, is greater than or equal to the pressure set value, the control chip is only connected with the indicating lamp. Compared with the prior art, the air suspension alarm solves the problem that the overload of a vehicle which is provided with the air suspension but is not provided with the necessary air suspension alarm is difficult to detect.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an air suspension alarm for trucks. Background technique [0002] In the past, the suspension of trucks on the market generally used spring steel shock absorbers. At present, more and more trucks have adopted air suspension shock absorbers. After adopting this kind of air suspension, trucks have the following advantages: 1. Air suspension The frame stiffness is non-linear and adjustable to adapt to different load requirements. The natural frequency remains unchanged, and a lower natural frequency can be obtained. The driving smoothness is good, the ride is comfortable, the service life of the vehicle is prolonged, and the damage of the vehicle to the road surface is reduced. 2. The height of the air suspension is adjustable, which can keep the vehicle level at a certain height, and can also raise or lower the height as needed. 3. The air suspension is light in ...
