Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention is provided.
The invention provides a power take-off driving device which mainly comprises a duplex input gear assembly 1, an output gear assembly 2, a wet-type multi-plate clutch 3, a shell 4 and an output shaft assembly 5; the duplex input gear assembly 1 and the output gear assembly 2 are arranged in the shell 4 in parallel, and the pinion of the duplex input gear assembly 1 is meshed with the gear of the output gear assembly 2; the wet-type multi-plate clutch 3 and the output gear assembly 2 are coaxially arranged in the shell; the central shaft of the output gear assembly 2 is fixedly connected with the outer hub of the wet-type multi-plate clutch 3, the output shaft of the wet-type multi-plate clutch 3 is rotatably connected with the shell through a bearing and is fixedly connected with an output shaft assembly 5, and an output flange is arranged on the output shaft assembly 5; a control oil inlet 6 and a lubricating oil inlet 7 are arranged on the shell, and the control oil inlet 6 is communicated with an oil cavity of the wet-type multi-plate clutch 3; the lubricant inlet 7 feeds lubricant to various locations.
The invention utilizes the existing power take-off mounting port of the original high-power AT gearbox to mount the power take-off device AT the power take-off mounting port, so that a main gear of a duplex input gear assembly is meshed with a power take-off driving gear 8 of the AT gearbox, a control oil output port of the high-power AT gearbox is connected with a control oil input port 6 of the power take-off device, a lubricating oil output port of the AT gearbox is connected with a lubricating oil input port 7 of the power take-off device, and the power take-off device is mounted on the AT gearbox.
After the engine is started, the input gear 8 of the AT gearbox drives the duplex input gear 1 to drive the output gear 2, when control oil pressure is input AT the control oil input port, the wet-type multi-plate clutch is combined, and the rotating speed and the torque of the output gear 2 are specially transmitted to the output shaft 5 through the wet-type multi-plate clutch 3, so that the power take-off driving function is realized.
When the control oil pressure is input into the control oil input port 6, the wet clutch 3 is combined, and the power takeoff works; the lubricating oil inlet 7 is used for obtaining lubricating oil, and lubricating and radiating internal parts.
The working principle is as follows: after the power take-off driving device is installed, the power take-off driving device can work together with the AT gearbox. After the vehicle engine starts, the AT gearbox starts to provide lubricating oil for the power take-off driving device to use, and the power take-off driving device is prevented from being damaged. An AT gearbox power take-off driving gear 8 connected with an engine drives a duplex input gear 1 to drive an output gear 2 to start running. When a driver operates and turns on the power take-off control switch, the AT gearbox starts to provide control oil for the power take-off driving mechanism, the control oil input port 6 has control oil pressure input, the wet multi-plate clutch 3 is pushed to be combined, the rotating speed and torque of the output gear 2 are transmitted to the output shaft 5 through the wet multi-plate clutch 3, and the power take-off driving mechanism starts to output power. When the driver operates the power take-off control switch to be turned off, the AT gearbox stops supplying the control oil to the control oil inlet 6 of the power take-off driving mechanism, the wet multi-plate clutch 3 is separated, and the power take-off driving mechanism stops outputting power.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
