Abstract
A tractor battery electrohydraulic controlling transfer case, which mainly comprises a casing body, a casing lower cover, an idle wheel, an idle wheel axle, a driven gear, a driven axle, a driven gear liner, a piston cylinder, a piston, a return spring, a driven sheet, an active friction sheet, etc. The piston cylinder is installed on the driven axle through a spline, the piston is installed in the piston cylinder, the return spring is coupled in the piston cylinder, one end is hold against the piston, and the other end is hold against the spring pressing plate; the clutch pressing disc is installed on the piston cylinder, the driven sheet and the active friction sheet are alternatively installed between the piston and the clutch pressing disc, the driven sheet is connected with the piston cylinder through a spline, and the active friction sheet is connected with the driven gear through a spline. The device can guarantee smooth power transmission of the front driving axle, the vehicle is required not to be stopped when being operated, and the transmission can be directly performed by the driver in the driving cab by operating the button of the solenoid reversing valve, and the operation is convenient.
Description
(1) technical field
The utility model belongs to the tractor field, relates to a kind of Farm Tractor Electrolyte Handling Transfer Case.
(2) background technique
At present, at home on the various model wheeled tractors of Sheng Chaning, the combination of transfer case is mostly adopted mechanical transmission with separating, and stick control engagement cover or slip change gear are realized.But mechanical handling mechanism is complicated, needs by the loaded down with trivial details mechanical transmission route of a cover Joystick to be introduced in the operator cabin, finish by the pilot control handle, not only difficult arrangement, handling comfort are poor, and will stop when handling, and articulate difficulty easily.
(3) summary of the invention
The purpose of this utility model is to provide a kind of manipulation simple transfer case, convenient transmission of power to front drive axle, and operating mechanism easy arrangement.
The technical solution of the utility model is: this transfer case mainly comprises housing, housing lower cover, idle pulley, idler shaft, driven gear, driven shaft, driven gear lining.It is characterized in that: piston cylinder is contained on the driven shaft by spline, piston is contained in the piston cylinder, return spring is enclosed within the piston cylinder, one end is close to piston, the other end is close to spring bearer plate, and clutch compressing disc is installed on the piston cylinder, and driven plate, active friction plate alternately are installed between piston and the clutch compressing disc, driven plate is connected with piston cylinder by spline, and active friction plate is connected with driven gear by spline.
The utility model can reach following beneficial effect, and this device can not only guarantee that the power of front drive axle transmits smoothly, and does not need to stop when handling, and can directly realize by the button of solenoid valve in the pilot control operator cabin, and is convenient and swift.
(4) description of drawings
Fig. 1 is the main TV structure sectional view of this Farm Tractor Electrolyte Handling Transfer Case.
(5) embodiment
As shown in Figure 1, electric liquid manipulation transfer case mainly comprises driven shaft 1, housing lower cover 2, piston cylinder 3, piston 4, return spring 5, active friction plate 6, driven plate 7, spring bearer plate 8, back-up ring 9, spacer 10, driven gear 11, driven gear lining 12, housing 13, clutch compressing disc 14, back-up ring 15, idler shaft 16, idle pulley 17.
Piston 4, return spring 5, spring bearer plate 8, back-up ring 9 are installed in the piston cylinder 3 successively, driven plate 7, active friction plate 6, clutch compressing disc 14, back-up ring 15 also are installed in the piston cylinder 3 successively, piston cylinder 3 is contained on the driven shaft 1 by spline, a spacer 10 is housed between piston cylinder 3 and the driven gear 11, driven gear 11 skies are enclosed within on the driven gear lining 12, and driven gear lining 12 is installed on the driven shaft 1.Housing lower cover 2 is fixed as one with housing 13 by bolt.Idle pulley 17 is enclosed within on the idler shaft 16 by needle bearing, and idler shaft 16 is supported on housing 13 tops, is fixed on the housing 13 by the elastic opening pin.
During work, power is passed to driven gear 11 by idle pulley 17 in the driving gear in the transmission case of back, the transfer case, and driven gear 11 dallies on driven gear lining 12.Press the button of operator cabin inner control transfer case, make the solenoid valve energising,, promote piston 4, return spring 5, compress active friction plate 6, driven plate 7, clutch compressing disc 14, back-up ring 15, piston cylinder 3 and driven gear 11 are combined as a whole to the transfer case fuel feeding.The rotation of transfer case driven gear 11 drives piston cylinder 3 and rotates, and rotates thereby drive driven shaft 1, by linking sleeve, rear propeller shaft etc. power is passed to front drive axle.Press button, make solenoid valve outage, the oil return of transfer case piston cylinder, return spring 5 rebounds, and active friction plate 6 is separated with driven plate 7, is cut off to the power of front drive axle.
