Description

technical field

[0001] The invention belongs to the technical field of power take-offs, and in particular relates to a full-power power take-off for automobiles. Background technique

[0002] The power take-off is a device for special-purpose vehicles to realize power output. At present, there are as many as five or six thousand types of power take-offs for special-purpose vehicles in developed countries, and there are more than 300 research and development patents. Especially in Europe and North America, there are very high requirements for special-purpose vehicle power take-offs. High, showing the trend of multi-port output and clutch. The power take-off control methods include mechanical, hydraulic, pneumatic, electric control, etc., and pneumatic control is more common. The development of domestic power take-off products is relatively slow. Most of the full-power power take-off products of automobiles are the power input of one shaft of the transmission, and the gear mes...

Examples

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] The power take-off of the present invention is located between the clutch and the transmission, and belongs to the sandwich type full-power power take-off, and its power input comes from the PTO clutch 3 independent of the main clutch 1 of the automobile, see figure 2 , the main clutch 1 adopts the driven disc assembly of ordinary clutch; see image 3 , the PTO clutch 3 is a splined drive plate with a shock absorber integrated in the pressure plate assembly, connected with the clutch cover through bolts, and rotates with the engine flywheel together with the pressure plate and clutch cover, so the power of the PTO clutch 3 Directly from the flywheel of the engine, not the driven disc assembly, so it is not affected by the engagement and disengagement of the master clutch 1 driven disc assembly.

[0026] see figure 1 , the overall structure of the fu...
