Problems solved by technology

The trailer track tracking performance of this structure is poor, and when it is running with the tractor, especially when running on a curve, it cannot run on the tractor's running track or close to the tractor's running track; thus making the trailer system in the turning It is difficult to operate and control when running on roads with small radius and narrow road surface. When multiple trailers are towed by a power tractor, the vehicle is even more difficult to operate and control.

Embodiment Construction

[0014] specific implementation plan

[0015] Such as figure 1 , 2 Shown embodiment 1 of the present invention, trailer comprises vehicle frame 7, the front and rear wheels 4,6 and wheel axles thereof under the vehicle frame, is used to connect the draw bar 2 of tractor and trailer, steering transmission gear mechanism, vertical shaft 8 etc. The rear wheel shaft is fixedly connected with the vehicle frame 7, the front wheel shaft 10 is fixed with the steering gear 3, the drawbar 2 is fixed with the traction gear 1, and the traction gear 1 and the steering gear 3 are all hinged on the vertical shaft 8, and the vertical shaft 8 is connected to the vertical shaft 8. The vehicle frame 7 is fixedly connected; the drawbar 2 drives the front wheel shaft 10 to rotate in the same direction around the vertical shaft 8 through the gear transmission mechanism; the draw angle θ of the drawbar 2 1 Steering angle θ with front wheel axle 10 2 The relation of θ 1 =kθ 2 , k>1. Gear transmi...

Abstract

A trailer with better trace tracking performance is composed of chassis, front and back wheels and their axles, a pull-rod for linking the trailer to tractor, steering gear mechanism and vertical axle. Said front wheel axle is linked to chassis via vertical axle and can rotate around the vertical axle under the drive of pull-rod can rotate around the vertical axle under the drive of pull-rod and steering gear mechanism. It features that the pull angle of pull-rod and the steering angle of front wheel axle must meet a predefined relation.

Description

technical field [0001] The present invention relates to road transport motor vehicles, in particular to trailers towed by motor vehicles. Background technique [0002] At present, it is widely used by people to draw a trailer with a motor vehicle for transportation. Existing trailer generally all is made up of vehicle frame, front and rear wheels and wheel axle, the drawbar that is used to connect tractor and trailer, and front and rear wheel axle is fixed on the below of vehicle frame. The trailer track tracking performance of this structure is poor, and when it is running with the tractor, especially when running on a curve, it cannot run on the tractor's running track or close to the tractor's running track; thus making the trailer system in the turning It is difficult to operate and control when running on roads with small radius and narrow road surface. When multiple trailers are towed by a power tractor, the vehicle is even more difficult to operate and control. Con...
