Problems solved by technology

At present, the power take-off gearbox still has the problem of high oil temperature caused by excessive oil stirring of the gears, the lubrication problem of the support bearing, the oil injection problem of the vent port caused by the oil rejection of the gear in the narrow inner cavity, and the connection problem between the output gear of the power take-off and the device. To use conventional measures to solve the above problems, it is necessary to make concessions in space, volume and other aspects and to increase external equipment. It is difficult to achieve the optimal configuration of performance, weight and working space in all aspects.

Abstract

The invention discloses a power take-off gearbox casing and a power take-off gearbox directly connected to a hydraulic pump, which solve the problems of excessive oil stirring and high oil temperature of the gears in the prior art, and solve the problems caused by the excessive stirring of the gears. It solves the problem of heat dissipation caused by oil and solves the problem of lubrication of multiple bearings. The scheme is as follows: a power take-off gearbox casing directly connected to a hydraulic pump comprises that the power take-off gearbox casing is sequentially divided into a ventilation cavity, a main cavity, a first oil storage cavity and a second oil storage cavity through inner ribs, Oil passages are respectively provided between the main cavity and the two oil storage cavities, the ventilation cavity is isolated from the main cavity, and a first oil collecting pool is arranged above the position between the first bearing and the second bearing in the main cavity, and the third A second oil collecting pool is arranged above the bearing.

Description

technical field [0001] The invention relates to the field of vehicle power take-off technology, in particular to a power take-off gear box shell and a power take-off gear box directly connected to a hydraulic pump. Background technique [0002] The power take-off gearbox is an additional power output device installed outside the gearbox. It can obtain power from the power take-off interface of the gearbox, transfer case and other power transmission devices to provide power to the vehicle hydraulic pump, water pump, compressor, generator, Motor etc. provide power. At present, the power take-off gearbox still has the problem of high oil temperature caused by excessive oil stirring of the gears, the lubrication problem of the support bearing, the oil injection problem of the vent port caused by the oil rejection of the gear in the narrow inner cavity, and the connection problem between the output gear of the power take-off and the device. To use conventional measures to solve ...
