Tractor load reversing transmission device

Abstract

The invention relates to a tractor load reversing transmission device. The tractor load reversing transmission device comprises a load reversing device, a main speed change device and an auxiliary speed change device, wherein the load reversing device, the main speed change device and the auxiliary speed change device are sequentially arranged, one end of the load reversing device is connected with an engine and the other end of the load reversing device is connected with the main speed change device. An input shaft, a reversing driven gear shaft and a reversing idler shaft are installed in the load reversing device; a main speed change driving shaft is installed in the main speed change device, the axes of the input shaft and the main speed change driving shaft are on the same line, and a power output front shaft penetrates through the internal part of the main speed change driving shaft. A reversing driving gear is sheathed on the input shaft, a forward clutch and a reverse clutch are fixedly installed on the input shaft, a reversing primary driven gear and a reversing secondary driving gear are integrated with the reversing driven gear shaft, and a reversing idler is integrated with the reversing idler shaft; the reversing idler is respectively and normally engaged with the reversing driving gear and the reversing primary driven gear, the reversing secondary driving gear is engaged with a reversing secondary driven gear and the reversing secondary driven gear is fixedly installed on the main speed change driving shaft.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor transmission device, in particular to a tractor load reversing transmission device. Background technique [0002] At present, domestic tractor gearboxes mostly use mechanical reversing methods such as synchronizers and meshing sleeves. When the tractor is reversing, it is necessary to disengage the main clutch to cut off the engine power, and then switch to the opposite gear after parking. At the same time, the driver has a large impact and manipulation force when shifting gears and changing directions, which brings discomfort to the driver and cannot meet the needs of users. Therefore, it is necessary to develop a reversing transmission device that can directly perform reversing operations without cutting off the power of the engine. Contents of the invention [0003] The object of the present invention is to provide a tractor load reversing transmission device with compact st...

Problems solved by technology

[0002] At present, domestic tractor gearboxes mostly use mechanical reversing methods such as synchronizers and meshing sleeves. When the tractor is reversing, it is necessary to disengage the main clutch to cut off the engine power, and then switch to the opposite gear after parking. The reversing is slow, which affects operating efficiency.

At the same time, the driver has a large impact and manipulation force when shifting gears and directions, which brings discomfort to the driver and cannot meet the needs of users.
