The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3: a kind of tractor dynamic power output variable speed case comprises: casing 5, input flange 2, input shaft 3, power-transfer clutch 4, clutch spindle 8, takeoff output flange 11, power divide shaft 14; It is characterized in that: three continual power output interfaces and the power output interface by clutch control are set on the power output speed changing box.
Described casing 5 one sides are provided with end cap, and the base that the casing lower end is provided with is connected with tractor frame; Described input shaft 3, clutch spindle 8 and power divide 14 3 of shafts to be installed on the casing 5 by bearing seat respectively; One end of described input shaft 3 is connected with the driving engine of trac. by input flange 2, directly obtains continual power from driving engine, and the other end of input shaft 3 is continual power output interface, is used to drive the vehicle-mounted hydraulic oil pump.Input shaft 3 is connected with clutch spindle 8 with clutch gear 7 by intermeshing input gear 6, for clutch spindle 8 provides power.Clutch spindle 8 stage casings are provided with power-transfer clutch 4, the coupled/separated of power-transfer clutch 4 is handled by hydraulic efficiency pressure system, one end of clutch spindle 8 is connected with the farm implements of trac. rear portion traction by takeoff output flange 11, transmission shaft 12, for the farm implements of trac. rear portion traction provide power.Clutch spindle 8 is also told gear 13 by intermeshing clutch gear 7 and power and is divided shaft 14 to be connected with power, provides power for power divides shaft 14, and power divides shaft 14 two ends to be the uninterruptible power output interface.Input gear 6 and clutch gear 7, clutch gear 7 and power are told the speed ratio relation of 13 of gears, have both guaranteed that the power take-off shaft of trac. obtained the rotating speed of regulation, guarantee that again three power output interfaces obtain necessary rotating speed.
Described power-transfer clutch 4 is a liquid clutch, also adorn drg 10 on the takeoff output flange 11, the power path of driving engine to the tractor dynamic power take-off (propeller) shaft can be engaged or cut off by independent clutch assembly, and when this power path is cut off, drg 10 can improve the reliability of this change speed gear box with suitable speed brake transmission shaft 12.
Described oil-feed seat 1 is provided with lubricating oil inlet 15 and power fluid imports and exports 16.Lubricating oil is to provide work with oil for power-transfer clutch 4 for this change speed gear box provides the lubrication oil of cleaning, power fluid.
The working process of this power output speed changing box is as follows: power is by input flange 2 inputs, when power-transfer clutch 4 engages, input gear 6 and clutch gear 7 by constant-mesh are sent to clutch spindle 8 with power, are connected takeoff output flange 11 on the clutch spindle 8 and are about to power and export outward by transmission shaft 12.
When power-transfer clutch 4 separated, clutch gear 7 dallied on clutch spindle 8, by 10 brakings of clutch operation interlock brake activation device, made clutch spindle 8 stalls, thereby cut off the power of tractor dynamic power take-off (propeller) shaft 12 simultaneously.
Because telling gear 13, input gear 6 and clutch gear 7, clutch gear 7 and power is the constant mesh gear transmission, therefore no matter clutch engagement whether, power can be told gear 13 → power from input flange 2 → input gear 6 → clutch gear 7 → power all the time and divide shaft 14, thereby realizes continual takeoff output.Input gear 6 and clutch gear 7, clutch gear 7 and power are told the speed ratio relation of 13 of gears, guarantee that the power take-off shaft of trac. obtains the rotating speed of regulation, guarantee that three power output interfaces obtain necessary rotating speed.
