Abstract

The utility model relates to the technical field of clutch power transmission, and provides a reversing wet clutch. The clutch comprises an input shaft and a connecting baffle plate on the side wall of the input shaft, and an annular baffle plate is arranged in a clutch hub body to divide the interior into a left chamber and a right chamber. And a clutch mechanism is arranged in each cavity and is respectively connected with a driving gear on the input shaft. The left clutch mechanism is responsible for the power combination and separation of the left cavity and the driving gear, and the right clutch mechanism is responsible for the right cavity. This design allows the shift between forward and reverse to be accomplished quickly and smoothly without interrupting the power transmission. Unlike the traditional mechanical gear shifting which needs to stop for interrupting power, the structure realizes independent control and switching of power and improves the continuity and efficiency of tractor operation. In addition, the independent clutch mechanism simplifies the control logic of the transmission system and reduces the operation complexity and the working strength of a driver.

Reversing wet clutch Technical Field The utility model relates to the technical field of clutch power transmission, in particular to a reversing wet clutch. Background In agricultural production activities, a tractor serves as a core power machine, and the switching operation of a forward gear and a backward gear of the tractor penetrates through a plurality of key operation links such as farmland, sowing, harvesting and the like. At present, a gear shifting mode adopted by a tractor is a mechanical gear shifting mode, when the tractor is required to be switched from a forward gear to a reverse gear or from the reverse gear to the forward gear, the existing mechanical gear shifting mechanism requires that a driver must completely stop a vehicle, and in the process, the driver needs to accurately tread a clutch pedal in the vehicle so as to interrupt the power output of an engine, and then the gear shifting operation can be performed. Therefore, the whole process is extremely complicated, each gear shift inevitably causes interruption of power transmission, and in an actual farmland operation scene, the negative influence caused by the interruption of the power is particularly remarkable. Taking the tillage as an example, after the tractor finishes a row of tillage tasks, the tractor needs to be switched to a reverse gear to drive back to a starting position so as to carry out the next row of tillage.
