General wide-angle mechanical boosting trailer

Abstract

The invention discloses a general wide-angle mechanical boosting trailer and belongs to the tractor technical field. The trailer comprises a first drive shaft, a transition shaft and a gear box; one end of the gear box, which extends out from the shell, is connected with a trailer rear axle through a second drive shaft; a shifting fork shaft and a shifting fork corresponding to the shifting fork shaft are arranged in the shell; one end of the shifting fork shaft extends out from the shell; the one end of the shifting fork shaft which extends out from the shell is connected with a rotating arm; and one end of the rotating arm is connected with an operating lever. With the general wide-angle mechanical boosting trailer of the invention adopted, the tractor can be boosted, so that rear driving can be realized, namely, a front-pull back-push boosting effect can be realized, and therefore, a tractor can run smoothly under situations of large slopes, soft ground surfaces, and muddy and slip road surfaces, and deadweight cargo capacity will not be affected assuredly in complex road surfaces. The trailer has the advantages of high-precision transmission ratio in power, accurate speed matching, small power loss, comfortable working environment for operators and being very humane. With the trailer adopted, problems such as high hydraulic temperature and burn of the operators can be solved.

Description

technical field [0001] The invention relates to the technical field of tractors, in particular to a trailer with a universal wide-angle mechanical assist mechanism. Background technique [0002] The power drive mode of current tractors is generally front drive, and its working principle is: the diesel engine of the tractor nose starts, and the power from the diesel engine is transmitted to the power bridge of the nose through the gearbox of the nose to realize the forward and backward of the nose, etc. Features. The gearbox of the machine head has a power output shaft, and then a pin is used to connect the machine head with the trailer to drag the trailer, that is, the driving mode of the tractor is that the power of the machine head drives the two powers of the machine head through the gearbox of the machine head. The wheels move forward, while the two rear wheels where the trailer is located are driven wheels, which are not driven by power and are only dragged. [0003]...

AI Technical Summary

Problems solved by technology

However, when the slope is large, the road surface is soft, the road surface is muddy and slippery, etc., the tractor with this structure will have problems such as difficulty in climbing the slope, less load, and safety accidents caused by slippery road surface.

In order to solve these problems, there have been reports and applications on the use of hydraulic pressure to power the rear wheel trailer. However, due to the defects of the structure itself, the current structure of the hydraulic power booster adopts hydraulic transmission, which has inaccurate transmission ratios, mismatched speeds, The power loss is large, the temperature of the hydraulic oil is high, and there are problems such as burns to the operator. The working environment of the operator is very uncomfortable and inhumane
