Front and back driving force output structure of automobile tractor without independent transfer case

Abstract

The invention provides a front and back driving force output structure of an automobile tractor without an independent transfer case, which comprises a frame, an engine, a front axle, a front axle propeller shaft, a rear axle and a rear axle propeller shaft and is characterized in that a combination transmission with front and back outputs is arranged on a dynamic output end of a vehicular engine,a forward-facing dynamic output end of the combination transmission is connected with the front axle by the front propeller shaft and a backward-facing dynamic output end is connected with the rear axle by the rear propeller shaft; and the forward-facing or backward-facing dynamic transmission direction is directly controlled by a gear engaging control lever. Compared with the current structure,the dynamic output structure omits a propeller shaft, a transfer case, an operating mechanism and a suspension fixation of the transfer case, simplifies the gear engaging control lever mechanism, reduces the material usage, saves the cost, simultaneously causes the structure of a vehicle chassis to be simple, makes room and is beneficial to the design arrangement of the whole vehicle parts.

Description

technical field

[0001] The invention relates to the power output structure of automobiles and tractors, in particular to the front and rear driving force output structures of automobile tractors without independent transfer gears. Background technique

[0002] At present, the power output structure of domestic front and rear drive cars and tractors is usually equipped with a transmission and an independent transfer case, which are connected through the intermediate transmission shaft, and the transfer case is connected with the front and rear axles through another transmission shaft respectively to realize the front and rear axles. drive. This structure needs to use three transmission shafts in total, and the transfer box needs to use a separate set of suspension fixing mechanism and gear shifting control mechanism. The structure of this whole set of devices is complex, which adds technical difficulty to the design and layout of the whole vehicle, and consumes a lot of mater...
