Semitrailer with turning protection device

Abstract

The invention discloses a semi-trailer equipped with a turning protection device. The semi-trailer includes a head, a trailer board, a controller, a turning reminding device, a turning protection device and an anti-pressure protection device. A turning reminder device for personnel, a trailer plate is hung behind the front of the vehicle, and turning protection devices are installed on both sides of the trailer plate, and an anti-pressure protection device is installed at the bottom of the trailer plate. The way of connection is to connect with the controller installed on the trailer board. The invention has the advantages of simple structure and convenient use, can effectively prevent traffic accidents when the trailer is turning, and ensure driving safety.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing technology, and in particular relates to a semi-trailer provided with a turning protection device. Background technique [0002] The inner wheel differential is the difference between the turning radius of the inner front wheel and the turning radius of the inner rear wheel when the vehicle is turning. For a trailer, it is the difference between the turning radius of the inner front wheel of the tractor and the inner rear wheel of the trailer. Due to the existence of the inner wheel difference, when the vehicle is turning, the trajectories of the front and rear wheels do not coincide. If you only pay attention to the passage of the front wheels and forget the inner wheel difference during driving, it may cause accidents where the rear inner wheels drive off the road or collide with other objects. Moreover, when the driver of the car is sitting in the cab, there is a blind spot i...

AI Technical Summary

Problems solved by technology

If you only pay attention to the passage of the front wheels and forget the difference between the inner wheels during driving, it may cause accidents where the rear inner wheels drive off the road or collide with other objects

And when the car driver sits in the cab, there is a blind spot of vision, the line of sight is blocked, and some areas outside the vehicle that cannot be directly seen

Due to the limited vision of the trailer driver, and the driver has a huge inner wheel difference when turning a large truck such as a semi-trailer, the rear inner wheel may drive out of the road or collide with other objects when the vehicle turns.

Therefore, when non-motor vehicles or pedestrians step into the blind spot of the inner wheel or are in the position of the inner wheel difference, the possibility of traffic accidents increases.
