A steering control method for a trailer includes firstly, controlling steering of front wheels of a tractor and acquiring deflection angles theta 1 of inner steering front wheels of front wheels of the tractor and an included angle alpha between a longitudinal central vertical plane of the tractor and a longitudinal central vertical plane of the trailer; and secondly, controlling steering of other pairs of steering wheels of the trailer, so that deflection angles of various other inner steering wheels on the tractor meet an inequality of arctan [(Li / L1)Xtan(theta 1)-3 degrees]< / =theta i< / ={arctan[(Li / L1)Xtan(theta 1)]+3 degrees, and deflection angles of various inner steering wheels on the trailer meet an inequality of [alpha-arctan(Z / P)-3 degrees]< / =theta j< / =[alpha-arctan(Z / P)+3 degrees]. The invention further provides a controller, the trailer and a steering system of the same. The steering control method, the controller, the trailer and the steering system have the advantages that the various wheels of the trailer can at least rotate around the same steering central area, abnormal abrasion to tires is obviously relieved, and the steering stability and the passing ability of the trailer are improved.

The invention discloses a road anti-collision method for a crossway, which uses an anti-collision device to prevent collision, the method is achieved mainly by triggering anti-collision expansion rodson both sides of an anti-collision crossbar after a car hits a guardrail to increase the impact area between the car and the guardrail. The purpose of the method is to provide the rod anti-collisionmethod for the crossway to solve the problem that a prior anti-collision device only uses passive energy absorption technology to cushion the impact, but neglects the situation that the car is easy todrift or turnover. An anti-collision device in the anti-collision method can increase the contact area with the vehicle in time when the device is hit, has the function of cushioning and shock absorption, can prevent the car from drift and eliminates or reduces the probability of overturning of the car.

The invention discloses a transportation machinery traction device with an adjustment function, which relates to the technical field of transportation machinery, and comprises a first casing, the upper surface and the lower surface of the inner wall of the first casing are both provided with a first chute, and The first sliding blocks are slidably connected in the two first sliding grooves, and the opposite surfaces of the two first sliding blocks are fixedly connected through the first connecting plate, and the sides of the first connecting plate are clamped with two first sliding blocks. set. The traffic machinery traction device with automatic adjustment function, through the cooperation between the first rotating shaft, the first spring, the steering mechanism, the third rotating shaft, the second spring and the second rotating shaft, can not only prevent the malfunctioning vehicle from The reason is that there is a rear-end collision with the consigned vehicle, which also makes there is a certain buffer force between the consigned vehicle and the faulty vehicle, which can reduce the impact of the faulty vehicle on the consigned vehicle due to inertia or failure to brake in time, so that the consigned vehicle and the faulty vehicle can be The faulty car plays a very good protective role.
