Problems solved by technology

[0002] At present, semi-trailers are mainly used in the domestic ultra-long cargo transportation market, but most domestic semi-trailers do not have follow-up steering functions. Road conditions with small width and small turning radius cannot pass normally
Chinese patent 99108000.9 discloses a "semi-trailer steering servo system controlled by a crank guide mechanism". This control system mainly uses mechanical force and hydraulic control to realize the steering function of a semi-trailer. It is a method of simulating the actual all-wheel steering. There is a certain error with the actual all-wheel steering

Embodiment Construction

[0011] See attached Figure 1-2 , an electronically controlled semi-trailer follow-up steering angle detection device, which includes: an angle sensor 1, a traction pin 2, a lever 4, an arc plate 7 and a saddle 8;

[0012] The lever 4 has an L-shaped structure, and its longer end is installed in the center through hole of the traction pin 2, and is connected with the end shaft of the angle sensor 1; the shorter end of the lever 4 is connected to the arc through the bolt 6 and the nut 5. The plate 7 is fixedly connected; the bottom of the traction pin 2 is fixedly connected with the semi-trailer frame 9;

[0013] See attached Figure 3-4 , when the tractor 10 turns, the saddle 8 rotates around the traction pin 2 fixed on the semi-trailer frame 9, and at the same time, the saddle 8 drives the arc plate 7 and the driving lever 4 to rotate around the traction pin 2, and then drives the angle sensor 1 rotates, the angle sensor 1 outputs an angle signal to the control actuator; th...

Abstract

The invention belongs to the technical field of trailer steering and particularly relates to an electrically-controlled semitrailer follow-up steering angle detection device. The electrically-controlled semitrailer follow-up steering angle detection device comprises an angle sensor, a traction pin, a shifting rod, an arc plate and a saddle. The shifting rod is in an L-shaped structure, the long end of the shifting rod is mounted in a center through hole of the traction pin and connected with an end shaft of the angle sensor, and the short end of the shifting rod is fixedly connected with the arc plate. The bottom of the traction pin is fixedly connected with a semitrailer frame, the saddle is mounted on a tractor by taking the traction pin as an axis of rotation, and the arc plate is positioned at a flared opening of the saddle. The electrically-controlled semitrailer follow-up steering angle detection device is simple in mounting, convenient to replace, capable of realizing real-time signal control of the tractor and the trailer, high in control precision and high in road condition applicability.

Description

technical field [0001] The invention belongs to the technical field of trailer steering, and in particular relates to a follow-up steering angle detection device. Background technique [0002] At present, semi-trailers are mainly used in the domestic ultra-long cargo transportation market, but most domestic semi-trailers do not have follow-up steering functions. Road conditions with small width and small turning radius cannot pass normally. Chinese patent 99108000.9 discloses a "semi-trailer steering servo system controlled by a crank guide mechanism". This control system mainly uses mechanical force and hydraulic control to realize the steering function of a semi-trailer. It is a method of simulating the actual all-wheel steering. There is a certain error with the actual all-wheel steering. Contents of the invention [0003] The object of the present invention is to propose an electronically controlled semi-trailer follow-up steering angle detection device to ensure pre...
