Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
If Fig. 1 is to as shown in Fig. 3, a kind of power takeoff electric motor drive, it comprises Hydraulic Pump 4, power takeoff 20, supporting plate 3, magnetic clutch assembly 2, with the main pulley 5 of circular groove, secondary belt pulley 7, connect the belt 6 of main pulley 5 and secondary belt pulley 7, the described power takeoff 20 input ends open end reserved with automobile gear change speed gear box 1 is connected, described power takeoff 20 and described Hydraulic Pump 4 are arranged on the below of supporting plate 3, be fixedly connected with side stand plate 13 in one end of this supporting plate 3, described magnetic clutch assembly 2 comprises adapter shaft 16, power-transfer clutch fixed cover 17, magnet coil 18, pressure wheel 11, the mouth of described power takeoff 20 is connected with one end of adapter shaft 16 by flat key or spline, the other end of this adapter shaft 16 and pressure wheel 11 are by flat key or spline sliding block joint, described clutch fixed cover 17 is contained on adapter shaft 16 by bearing carrier ring, described main pulley 5 is contained on power-transfer clutch fixed cover 17 by carrying bearing carrier ring, described magnet coil 18 one end are fixed on power-transfer clutch fixed cover 17 by set pin, these magnet coil 18 remainders are sleeved in the circular groove of main pulley 5, described secondary belt pulley 7 is fixedly connected on the main shaft of Hydraulic Pump 4, described Hydraulic Pump 4 is fixed on side stand plate 13.
As a kind of improvement of the present utility model, described Hydraulic Pump 4 is fixed on swivel mount 8, described swivel mount 8 is hinged near a side and the side stand plate 13 of power takeoff 20, hinged away from a side of power takeoff 20 and one end of adjusting lever 9, the other end of this adjusting lever 9 is connected with side stand plate 13, described adjusting lever 9 is threaded with one end that side stand plate 13 is connected, one end at side stand plate 13 is welded with otic placode, on this otic placode, have the tapped bore that can pass for adjusting lever 9, this screwed one end of adjusting lever 9 is fixedly linked by nut 12 and side stand plate 13.Like this, can regulate the distance between power takeoff 20 and Hydraulic Pump 4 by the nut 12 on adjusting lever 9, and then can make the distance variable between main pulley 5 and secondary belt pulley 7, so just the installation and removal of belt 6 can be facilitated, can also be in the time that belt 6 be loose because using for a long time, by strengthening the distance between main pulley 5 and secondary belt pulley 7, make loose belt 6 still can continue to use, like this with regard to further increased the reliability of this device and extended drive disk assembly service life.
As further improvement of the utility model, on described side stand plate 13, there are four slotted holes, on described supporting plate 3, there is the circular port corresponding with side stand plate 13, side stand plate 13 is bolted on a splice 3 by four.Like this, can further adjust the distance between power takeoff 20 and Hydraulic Pump 4, just can further adjust the distance between main pulley 5, secondary belt pulley 7, thus the installation and removal of more convenient belt 6.
Further improving as of the present utility model, in order to make the friction force between belt 6 and main pulley 5 and secondary belt pulley 7 large as much as possible, can preferred described belt 6 be V-belt.
As the alternative improvement of the utility model, supporting plate 3 is bolted the connecting panel 10 with upright arm in the one end near automobile gear change speed gear box 1, this connecting panel 10 is at the semicircular arc mating with engine case that is shaped as away from main pulley 5 one sides, and the arch section of described connecting panel 10 is fixedly connected with automotive engine shell by bolt.Like this, can make the fixing further enhancing between this device and automobile.
After automobile starting, the entry into service under the drive of automobile gear change speed gear box 1 inner gear of gear cluster in power takeoff 20, and the clutch end of power takeoff 20 is connected with adapter shaft 16 by flat key or spline, this adapter shaft 16 passes through flat key or spline sliding block joint with pressure wheel 11, thereby drive pressure wheel 11 to turn round by adapter shaft 16, when automotive engine is during in idling, open the button of controlling magnetic clutch assembly 2 in operator's compartment, after 2 energisings of magnetic clutch assembly, magnet coil 18 in main pulley 5 inner sides produces magnetic, thereby make belt pulley 5 produce the attractive force to pressure wheel 11, pressure wheel 11 is slided to the direction of main pulley 5, then compress main pulley 5 and drive main pulley running, main pulley 5 drives secondary belt pulley 7 to turn round by belt 6, thereby for Hydraulic Pump 4 provides pulsation-free power resources, like this, just can realize band year has cut.
In the time that needs Hydraulic Pump 4 quits work, only need the button of closing control magnetic clutch assembly 2, can make magnet coil 18 power-off, thereby make main pulley lose the attractive force to pressure wheel 11, pressure wheel 11 under High Rotation Speed can with main pulley automatic trip from, main pulley 5 shuts down then, Hydraulic Pump 4 source that runs out of steam, like this, just can realize and throw off load.
In the time that overload phenomenon occurs, the secondary belt pulley 7 that the main shaft of Hydraulic Pump 4 connects can shut down, because main pulley 5 can be synchronizeed with secondary belt pulley 7 under the drive of belt 6, and the rotating speed of pressure wheel 11 almost still remains unchanged, now, friction force between pressure wheel 11 and main pulley 5 because overload phenomenon generation by extremely huge increase, and attractive force between pressure wheel 11 and main pulley 5 is not enough to overcome friction force now, so can produce skidding between pressure wheel 11 and main pulley 5, thereby can be in the situation that effectively having protected each drive disk assembly not sustain damage, the transmission of power of power takeoff 20 is stopped automatically, in the time that overload phenomenon disappears, friction force between pressure wheel 11 and main pulley 5 has reduced again, now, attractive force between pressure wheel 11 and main pulley 5 can overcome again the friction force between pressure wheel 11 and main pulley 5, thereby make main pulley 5 normal operations, send power to Hydraulic Pump 4 by belt 6 and secondary belt pulley 7 again, like this, just realized and recovered the transmission of power automatically.
In use procedure, because swivel mount 8 one sides and supporting plate 3 are hinged, the opposite side of swivel mount 8 and adjusting lever 9 are hinged, so can regulate by the nut 12 on adjusting lever 9 angle of swivel mount 8, or by adjusting the fixed position of side stand plate 13 and supporting plate 3, thereby increase or reduce the distance between Hydraulic Pump 4 and power takeoff 20, make the installation and removal of belt 6 more convenient, and, when belt 6 is because using a period of time when loose, can increase the distance between Hydraulic Pump 4 and power takeoff 20, like this, also just strengthened the distance between secondary belt pulley 7 and main pulley 5, just can make loose V-belt still can continue to use, so further increased the reliability of this device and extended drive disk assembly service life.
