Problems solved by technology
[0003] The structure of this traditional power take-off device has the following disadvantages in use: 1. No matter whether the working device needs power or not, the hydraulic pump is always working, which consumes energy; 2. During operation, the clutch directly drives the power take-off The work of the clutch increases the load of the clutch, accelerates the wear of the clutch, and shortens its service life; 3. The clutch is easily damaged due to large wear, and its replacement and maintenance costs are high; 4. The equipment structure is complex, and the overall layout occupies The space is larger and the parts used are more, which makes the cost high

Embodiment Construction
[0012] figure 1 The overall structure of the present invention is shown. The crankshaft power take-off 2 is installed between the crankshaft 1 of the automobile engine and the clutch 6, the crankshaft power take-off is connected with the transmission shaft 3 through a universal joint, and the other end of the transmission shaft is connected with the power input shaft of the separator 4 through a flange , the power output shaft of the separator 4 is engaged with the hydraulic pump 5 .
[0013] figure 2 The structure and working principle of the separator 4 are shown: Figure (a) shows that the hydraulic pump is in a working state, and figure (b) shows that the hydraulic pump is in a stopped working state.
[0014] Separator 4 is mainly made of electronically controlled cylinder 7, shift fork 8, power input shaft 9, spline sleeve 10, power output shaft 11, and electronically controlled cylinder 7, shift fork 8, spline sleeve 10 are connected in sequence.

A new power taking off devices are dedicated to the vehicle. It adds a separator between the hydraulic pump and the drive shaft, the separator consists of electronic control cylinder, fork, power input shaft, spline sets, power output shaft. Control the hydraulic pump by spline sets and the power input shaft are connected or not. The invention not only lightens the load of the clutch and extends its useful life, but also reduces energy consumption and noise, and leaves out the slipping wheel of the traditional power taking off devices, thereby reduces the space taked by crankshaft power taking off devices and the cost.
Description
technical field [0001] The utility model belongs to a power take-off system used for a working device of a special automobile. Background technique [0002] Traditional special-purpose vehicles, such as: asphalt spreaders for road construction, gravel spreaders, etc., take power from the driven plate or pressure plate of the clutch, and some directly take power from the crankshaft, and through the power take-off The multi-stage gears in the device are meshed for transmission, and the force is transmitted to the transmission shaft. The transmission shaft and the hydraulic pump are connected through a flange to drive the hydraulic pump to work. [0003] The structure of this traditional power take-off device has the following disadvantages in use: 1. No matter whether the working device needs power or not, the hydraulic pump is always working, which consumes energy; 2. During operation, the clutch directly drives the power take-off The work of the clutch increases the load of...
