Problems solved by technology

At the same time, whether the trailer body is balanced or not has a great impact on safe driving, especially for trailers with heavy loads, if the body is seriously unbalanced, it may cause the trailer to roll over.
However, there is no automatic adjustment method for trailer body height and body balance.

Abstract

The automatic adjustment method of the height of the trailer body and the balance of the body of the trailer based on the air suspension of the present invention is realized by the following steps: a). Judgment of the lifting speed of the body; b). Judgment of the lifting load of the body; c). Judgment of the balance of the body; d) .Road condition judgment; e).General height body lift control; f).Intelligent height body lift control. The automatic adjustment method of the trailer body balance is realized through the following steps: 1). Body balance detection; 2). Left tilt adjustment; 3). Right tilt adjustment. The automatic adjustment method of trailer body height and body balance of the present invention adjusts the height of the body according to the current speed and load calculated by the formula, and adjusts the left and right sides of the body by raising one side of the axle or lowering the other side when the body tilts The side height is consistent, which ensures the safety of the trailer during driving.

Description

technical field [0001] The invention relates to a method for automatically adjusting the height and balance of a trailer body, and more specifically, to an air suspension-based system for adjusting the height and balance of the vehicle body according to the detected load, vehicle speed, balance state of the vehicle body, and road conditions. An automatic adjustment method for trailer body height and body balance. Background technique [0002] In GB7258-2017 "Technical Conditions for Motor Vehicle Operation Safety", the rear axle of dangerous goods transport trucks with a total mass greater than or equal to 12000kg is added. The content of the air suspension, so the replacement of leaf spring suspension by air suspension has become an industry necessity. [0003] The current mainstream technical solution in the market is: the air spring suspension system relies on the height valve to detect the height of the vehicle body, so as to maintain the stability of the vehicle body h...
