Abstract

The invention discloses a three-axle trailer steering system, comprising a hydraulic system and a steering mechanism, wherein the hydraulic system controls the steering mechanism, and the steering mechanism controls wheels of a three-axle trailer to swerve. The three-axle trailer steering system further comprises a sensing system and a control system, wherein the sensing system is used for sensing a tractor swerving angle, the sensing system is mounted on the steering mechanism, and the sensing system is electrically connected with the control system; the control system is used for receiving a signal of the sensing system and controlling the hydraulic system, and the control system comprises a central controller. The three-axle trailer steering system has simple structure, and can realizeautomatic steering of the three-axle trailer. The three-axle trailer steering system has the following benefits that: 1, a PLC (Programmable Logic Controller) technology is used in the trailer, and automatic control is realized by combination with a hydraulic solenoid valve; 2, two groups of steering axle serial oil circuits are provided for realizing synchronization of two groups of steering axles; 3, an axle head of each steering axle is provided with a hinge, and a thrust wheel can rotate for certain degrees around a hinge pin, so that transverse dragging in a steering process is reduced; 4, manual operations are configured in a driving cab, which facilitates operations of meeting other cars, backing up, moving to other sites, and the like, for a driver.

Description

technical field [0001] The invention relates to the field of truck trailers and automatic control, in particular to a steering system for a three-axle trailer. Background technique [0002] Semi-trailer is the most ideal model for "drop-and-pull transportation", "section transportation" and "roll-on-roll-off transportation". It has good transportation economic benefits, so the demand for semi-trailers in the transportation market is increasing day by day. There are more than 220 trailer manufacturers nationwide, with about 13 million trailers. [0003] At present, trailers in foreign countries are relatively advanced, ranging from a few tons to nearly 200 tons, and the automatic steering bridge is mostly used for large trailers of more than 100 tons. Moreover, the price is astonishingly expensive. In addition, super-large tonnage trailers are limited by roads and bridges in China, so they are currently less used. [0004] According to the survey, in the running cost of the...
