Summary of the invention
The utility model can not satisfy the problem that heavy motor vehicle uses needs in order to solve existing power takeoff, provides a kind of heavy duty automobile gear box rearmounted single-stage power takeoff.
The utility model adopts following technical scheme to realize:
The utlity model has following beneficial effect: the rearmounted single-stage power takeoff of heavy duty automobile gear box, comprise power takeoff housing that is connected in the change speed gear box rear end and the power takeoff output shaft that docks by needle bearing with change speed gear box power taking output shaft, change speed gear box power taking output shaft and power takeoff output shaft axle center are on same straight line, the butt end that it is characterized in that change speed gear box power taking output shaft and power takeoff output shaft all is provided with identical male splines separately, be provided with on the power takeoff output shaft of male splines end and be with power takeoff tooth cover, have the spline that is complementary with male splines on the power takeoff tooth cover inner periphery, have the fork slot that is complementary with shift fork on the power takeoff tooth cover excircle, shift fork one side connects the fork axle, opposite side connects piston, sheathed pull back spring on the declutch shift shaft, have admission port on the power takeoff housing of piston one end, the contacting indicator cock is set, the power takeoff bead of the other end attachment flange structure of power takeoff output shaft on the declutch shift shaft vertical direction.
The utility model is the direct output type power takeoff of single-stage, directly is connected with change speed gear box power taking output shaft, and the axle center of power takeoff output shaft and change speed gear box power taking output shaft is on same straight line.The spline that connects change speed gear box power taking output shaft and power takeoff output shaft by power takeoff tooth cover makes power takeoff work.
The utlity model has following beneficial effect: easy for installation, reliable operation, load-carrying capacity are big, compact conformation, the general layout little, that help car load that takes up room, and can satisfy the multiple service condition of heavy motor vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the A of Fig. 1 is to scheme drawing
Fig. 3 is the B-B section-drawing of Fig. 1
Among the figure: 1-power takeoff housing, 2-declutch shift shaft, 3-pull back spring, 4-power takeoff tooth cover, the 5-seal ring, 6-power takeoff bonnet, jump ring in the 7-power takeoff output shaft, 8-, 9-power takeoff bead, 10-bead jam nut, 11-key, 12-plain cushion, the 13-oil sealing, the outer jump ring of 14-, 15-bearing, 16-locating dowel pin, 17-touches pin, 18-indicator cock, 19-needle bearing, 20-change speed gear box power taking output shaft, the 21-shift fork, 22-admission port, 23-piston
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
The rearmounted single-stage power takeoff of heavy duty automobile gear box, comprise power takeoff housing 1 that is connected in the change speed gear box rear end and the power takeoff output shaft 7 that docks by needle bearing 19 with change speed gear box power taking output shaft 20, change speed gear box power taking output shaft 20 and power takeoff output shaft 7 axle center are on same straight line, the butt end that it is characterized in that change speed gear box power taking output shaft 20 and power takeoff output shaft 7 all is provided with identical male splines separately, be provided with and be with power takeoff tooth cover 4 on the power takeoff output shaft 7 of male splines end, the power takeoff tooth overlaps and has the spline that is complementary with male splines on 4 inner peripherys, the power takeoff tooth overlaps and has the fork slot that is complementary with shift fork 21 on 4 excircles, shift fork 21 1 sides connect fork axle 2, opposite side connects piston 23, sheathed pull back spring 3 on the declutch shift shaft 2, have admission port 22 on the power takeoff housing 1 of piston 23 1 ends, on declutch shift shaft 2 vertical direction contacting indicator cock 18 is set, the power takeoff bead 9 of the other end attachment flange structure of power takeoff output shaft 7.
The utility model makes power takeoff work by the spline that power takeoff tooth cover 4 connects change speed gear box power taking output shaft 20 and power takeoff output shaft 7, by several bolts power takeoff housing 1 is connected in the change speed gear box rear end, then other parts of power takeoff are installed, its stable drive is reliable, and is easy for installation.And be equipped with power takeoff indicator cock 18, and when power takeoff was worked, indicator cock 18 was connected, and the indication power takeoff is started working.
Concrete power transmission route is: by power takeoff tooth cover 4 change speed gear box power taking output shaft 20 and power takeoff output shaft 7 are coupled together, output power by the power takeoff bead 9 that is installed in the flange arrangement on the power takeoff output shaft 7 then.
Concrete mode is: the air that feeds 0.7-0.8MPa at the admission port 22 of power takeoff bonnet 6, air pressure promotes piston 23 motions, piston 23 drives power takeoff fork axle 2, fork axle 2 drives fork 21, power takeoff fork 21 promotes power takeoff tooth cover 4, thereby power takeoff tooth cover 4 is engaged, and transmission of power begins, power takeoff work.When not needing power takeoff work, cut off the air of admission port, by pull back spring 3 the power takeoff transmission of power is interrupted.(annotate: wherein fork axle 2, fork 21, piston 23 threes are one.)
When power takeoff is worked, by fork axle 2 and indicator cock 18 effects,, indicator cock 18 is connected with the contact position compression of indicator cock 18, the prompting power takeoff is started working; When power takeoff quit work, indicator cock 18 was disconnected, and the prompting power takeoff quits work.
According to user's specific requirement, can change the connection mode of power takeoff and change speed gear box flexibly, torque reserve is big, by practice test, can satisfy the operating needs of heavy motor vehicle various working.
