Abstract
The utility model relates to a power takeoff for special vehicles, which comprises a box body of the power takeoff, and a power input gear, a transitional gear and a power output gear which are arranged in the box body. The utility model has the main point that the front end of the box body of the power takeoff is fixedly provided with a front connecting disk which is fixed to a back casing of an engine, a back connecting disk is fixed to a front casing of a speed-changing box, a clutch operating mechanism penetrates through a shaft hole of the power input gear and the front end of the shaft of the power input gear is connected with a connecting disk which is fixed on a casing of the clutch. The power takeoff for special vehicles has the advantages of smooth operation and low noise without being affected by running vehicles.
Description
The utility model relates to a kind of matching component of speciality car, especially for the power takeoff of the automobile power of Special Work.
At present, utilize the General Motors chassis to carry out the special vehicle repacking, adopt directly installed the power power takeoff more on transmission shaft, its weak point is, this power takeoff is subjected to the restriction of autoclutch and change speed gear box gear, promptly when power-transfer clutch is in released state, or shifter bar is when being in the neutral gear gear, propeller-shaft stops operating, at this moment power takeoff thereon also just quits work, because of power takeoff no power takeoff in this case, so the vehicle-mounted specialized equipment of supporting with it bonded assembly also is forced to out of service.In addition, when the installing power takeoff, be subjected to the restriction of locus again, particularly common autotruck only has 90MM from power-transfer clutch to change speed gear box, and the power takeoff of general structure can't be installed at all.
The purpose of this utility model be to overcome above-mentioned weak point of the prior art and provide a kind of be not subjected to stop influence, can install and with the special vehicle power takeoff of automotive engine synchronized operation.
The purpose of this utility model is realized by following technology side:
A kind of special vehicle power takeoff, it comprises the power takeoff casing, places power input gear, transition gear and power output gear in the casing, its main points are that power takeoff casing front end is fixed with preceding terminal pad, preceding terminal pad is captiveed joint with the driving engine back cover, the back terminal pad of power takeoff casing is captiveed joint with the fore shell of change speed gear box, clutch operation passes from the axis hole of power input gear, the axle front end of power input gear is captiveed joint with terminal pad, on the clutch-bell cover that terminal pad is fixed on engine flywheel is captiveed joint.
Above-mentioned power takeoff, the axle front end of described power input gear is that spline is connected with terminal pad.
In order to make stable drive, noise is little, and moment is big, and power input gear, transition gear and power output gear all can adopt 15-30 ° helical wheel.
In order to improve lubricant effect, axle front end at power output gear is connected with oil pump, be connected with transport pipe between the oil outlet of the oil-sucking hole of oil pump and power takeoff casing, be connected with transport pipe between the oil passage of the oil outlet of oil pump and power takeoff casing upper end and the fuel feed hole of tween drive shaft.
In order to improve sealing effectiveness, be respectively equipped with U type or J type reinforced seal oil sealing at the axle two ends of power input gear.
For the ease of takeoff output, be fixed with the takeoff output flange at the shaft rear end of power output gear.
Special vehicle power takeoff stable drive provided by the utility model, noise be little, be not subjected to driving, stopping influences, can with automotive engine synchronized operation.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, this special vehicle power takeoff comprises power takeoff casing 8, place the power input gear 21 in the casing 8, transition gear 12 and power output gear 10, casing 8 front ends are fixed with preceding terminal pad 22, this dish is captiveed joint with the back cover 3 of automotive engine 4, connecing dish 19 behind the casing 8 captives joint with the fore shell 18 of automobile gearbox 16, clutch operation 15 passes from the hole on the axle 14 of power input gear 21, axle 14 front ends of power input gear 21 are captiveed joint with terminal pad 1, terminal pad 1 is fixed on the clutch-bell cover 23 of captiveing joint with engine flywheel, axle 14 front ends of gear shown in the figure 21 are connected for spline with terminal pad 1, gear 21,12,10 are 15 ° of helical teeth, the number of teeth is respectively 30,35,30, modulus M=4, overall gear ratio are 1, outputting power 40NM turns to same driving engine.Be anti-leakage of oil, axle 14 two ends of power input gear 21 are respectively equipped with U type or J type reinforced seal oil sealing 2,17.
For ease of takeoff output, axle 7 rear ends of power output gear 10 are fixed with takeoff output flange 11, and axle 7 can select for use spline to be connected with 11 of flanges.
In addition, axle 7 front ends of power output gear 10 link to each other with oil pump 6,20 of the oil outlets of the oil-sucking hole of oil pump 6 and power takeoff casing 8 are connected with transport pipe, and the oil passage 9 of the oil outlet of oil pump 6 and power takeoff casing 8 upper ends and 13 of the fuel feed holes of tween drive shaft 5 are connected with transport pipe.
During work, as long as automobile engine starting, flywheel shell 23 will rotate synchronously, and the terminal pad of fixing on it 1 also rotates synchronously, promptly drives power input gear 21 with terminal pad 1 by spline bonded assembly axle 14 and rotates, and makes power takeoff in running order.Therefore, this power takeoff is not subjected to autoclutch from, the influence of closing state.
When utilizing common truck chassis and using this power takeoff to reequip, it is moving that the relevant drive disk assembly of former car engine and change speed gear box is only done some micromodification.This power takeoff is applicable to multiple vehicles such as mixermobile, fire extinguishing tanker, water truck.
