Abstract

The invention provides a trailer lifting axle automatic control system. The system comprises a height sensor which collects the height of a trailer airbag in a vertical direction, and obtains the height information of a trailer body; a trailer electronic braking system continuously collects trailer loads, obtains trailer load data, processes the load data and then sends a control instruction; an air suspension electromagnetic valve is connected with an air source, and is respectively connected with the height sensor and the trailer electronic braking system; the air suspension electromagneticvalve receives a control instruction sent by the trailer electronic braking system. Inflation or deflation of the trailer air bag is controlled; therefore, the trailer lifting axle ascends or descends; according to the real-time load data of the trailer air spring, the trailer lifting axle is automatically controlled to ascend and descend, so that the mode that the trailer lifting axle is manuallycontrolled to ascend or descend is replaced, automatic ascending and descending of the lifting axle are achieved, the lifting axle control process is more intelligent, oil consumption is reduced, andlosses of trailer tires in a non-full-load state are reduced.

Description

technical field [0001] The invention belongs to the technical field of trailer lifting axles, and in particular relates to an automatic control system and control method for trailer lifting axles. Background technique [0002] The trailer lifting axle system is a free-rising axle, thereby changing the height of the axle tire in the vertical direction, making it contact with the ground or floating away from the ground. Therefore, when the trailer is heavily loaded, the vehicle axle can be lowered so that the tires are in contact with the ground to carry the load, and when the trailer is lightly loaded, the vehicle axle can be lifted to allow the tires to leave the ground to save fuel consumption. [0003] In the prior art, the control of the lifting bridge mainly adopts pneumatic, hydraulic or even hand-cranked methods as power assistance to control the lifting and falling of the lifting bridge, and most of them are realized by manually observing the load and completing the m...
