A multi-axle trailer wheel follow-up steering sensor control device

Abstract

The invention discloses a wheel follow-up steering sensing control device of a multi-axle trailer, and belongs to the field of vehicle engineering. The wheel follow-up steering sensing control device comprises a mechanical sensing mechanism, a signal transmitting mechanism, a mechanical-hydraulic servo valve, a steering actuation cylinder, a feedback signal cylinder, a steering rod system, a steering oil source and an energy accumulator. The mechanical sensing mechanism receives an included angle signal and converts the included angle signal into a displacement signal through the signal transmitting mechanism according to a certain proportion. The mechanical-hydraulic servo valve receives the displacement signal and controls the steering actuation cylinder to move precisely. The steering actuation cylinder drives the steering rod system to correspondingly swing, and then pushes a steering axle wheel of the trailer to steer in a follow-up mode. Meanwhile, the feedback signal cylinder provides a feedback signal for the mechanical-hydraulic servo valve to ensure the precision of follow-up steering of the wheel of the trailer. The wheel follow-up steering sensing control device has the advantages that the structure is simple and reliable, mounting and maintenance are easy, the trailer with the device is good in stability, high in follow-up performance and high in synchronous steering precision, the problem that tires of the trailers are worn seriously is solved, the aim of safe steering in a narrow space is achieved, and the running safety of the trailer can be guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, in particular to a multi-axle trailer wheel follow-up steering sensor control device. Background technique [0002] Trailer is an important part of the transportation industry. It is widely used in fields, workshops, shopping malls and airports due to its convenient use and large carrying capacity. Among them, there are many turns and dead ends in airports, workshops and shopping malls, while fields are faced with more complex road surfaces, which put forward higher requirements for the steering performance of trailers. The existing full-trailer trailer generally adopts a turntable mechanism capable of 360° axis steering. Although the problem of turning the trailer in a narrow space is solved, the center of gravity of the whole vehicle is increased, and the driving stability of the trailer is poor. With the rapid development of the logistics industry and the As the weight of the trailer gradua...
