Embodiment Construction
[0009] Attached below figure 1 The present invention will be further described.
[0010] A lifting bridge reversing lifting device, comprising: a cab lifting bridge switch 2 connected to a car key power supply 1 and a lifting bridge solenoid valve 5, the lifting air bag is connected to the air storage tank through the lifting bridge solenoid valve 5, and the control of the lifter solenoid valve 5 The end is connected to the cab lifting bridge switch 2 through the reversing lifting relay 3, and the control end of the reversing lifting relay 3 is connected to the reversing light signal line 4. When driving forward normally, the reversing signal line 4 has no electricity, and the reversing lifting relay 3 does not work. Since the reversing lifting relay 3 is a normally closed relay, it does not affect the on-off of the circuit, the lifting axle solenoid valve 5 works normally, and the axle can be normal. Lift or carry. When reversing, the reversing signal line 4 is energized, t...

Disclosed is a lifting device for a lifting axle during reversing. The lifting device for the lifting axle during reversing comprises a cab lifting axle switch connected to an automobile key power source, and a lifting axle electromagnetic valve. A lifting airbag is connected to an air reservoir through the lifting axle electromagnetic valve; the control end of the lifting axle electromagnetic valve is connected to the cab lifting axle switch through a reversing lifting relay; the control end of the reversing lifting relay is connected to a reversing light signal line. When a vehicle runs forwards normally, the reversing light signal line is not energized, the reversing lifting relay does not work, as the reversing lifting relay is a normally-closed relay, the connection and disconnection of the line are not influenced, the reversing lifting relay works normally, and an axle can be normally lifted or carried. When the vehicle is reversed, the reversing light signal line is energized, a magnet exciting coil of the reversing lifting relay is energized, the normally-closed contact of the output end is disconnected, at the moment, the lifting axle electromagnetic valve switches the power off and the axle is to be lifted no matter whether the axle is at a carrying status or not. By means of the lifting device for the lifting axle during reversing, the tires do not make contact with the ground, thus the situation of tire wear due to incorrect steering is avoided.
Description
technical field [0001] The invention relates to a reversing lifting device for a lifting bridge. Background technique [0002] Today, more and more trucks are equipped with lifting axles. Its advantage over ordinary axles is that it has good economy. The axle can be lowered to carry the weight when it is heavy-loaded, and it can be lifted when it is empty or light-loaded, so that there is no frictional resistance between the wheels and the ground, reducing fuel consumption, and at the same time Reduce tire wear. However, one disadvantage of the lifting axle is that the axle is generally follow-up. If the axle is in a loaded state during the reversing process, the tires on the axle are prone to misdirection, which will aggravate the wear of the tires. In order to solve this problem in the market, a reverse locking mechanism is generally installed so that the hoisting axle wheels do not rotate when the vehicle is reversing. Installing this mechanism additionally costs more....
