Synchronizer gear shifting device of shuttle-type gearbox of tractor of 25-40 horsepower

Abstract

The invention discloses a synchronizer gear shifting device of a shuttle-type gearbox of a tractor of the 25-40 horsepower and belongs to the technical field of tractor gearboxes. The synchronizer gear shifting device comprises a front shell, a rear shell, a shuttle gear driving shaft, a shuttle gear middle shaft, a first shaft and a second shaft, wherein the front shell and the rear shell are connected in a sealed mode through bolts and arranged from front to back. The synchronizer gear shifting device is characterized in that the shuttle gear driving shaft and the shuttle gear middle shaft are installed in the front shell, the first shaft and the second shaft are installed in the rear shell, the axis of the shuttle driving shaft and the axis of the first shaft are located on the same straight line, and the axis of the shuttle gear middle shaft and the axis of the second shaft are located on the same straight line. The synchronizer gear shifting device has the advantages of being reasonable in design, easy to machine, comfortable to operate and the like. On the premise that the conventional structure of an original tractor is not changed, the local improvement is conducted, multiple kinds of allocation can be achieved on the same chassis, and modularization of products is easy to achieve; the risk that a spline conjunction gear is damaged is lowered, and the service life is prolonged; the installation structure of a sliding tooth and engagement sleeve gear shifting type machine is not influenced.

Description

technical field [0001] The invention relates to the technical field of tractor gearboxes, in particular to a gear shifting device for a synchronizer of a 25-40 horsepower tractor shuttle gearbox. Background technique [0002] At present, the 25-40 horsepower tractor shuttle gearboxes in the domestic prior art generally use sliding gears or meshing sleeves to shift gears. This gear shifting mode has difficulties in shifting gears, abnormal noises, etc., and is easy to shift during shifting. The spline teeth are damaged by the collision, and the heavy-duty operation is prone to disengagement after the gear is engaged, which affects the normal operation of the tractor. In addition, existing tractors generally have cumbersome operations, and drivers are prone to fatigue, which leads to higher and higher requirements for tractor operation comfort by users. Contents of the invention [0003] The technical task of the present invention is to provide a 25-40 horsepower tractor sh...
