Description
Technical field
This utility model belongs to tractor field, relates to a kind of wheeled tractor self shifter power take-off mechanism.
Background technology
At present, on the tractor produced at home, power output shift control mechanism majority uses mechanical handling bar gearshift, and this gearshift mode needs a set of loaded down with trivial details mechanical handling mechanism, during conversion power output speed, spindle nose should be changed, use stick gearshift again so that complete machine is arranged numerous and diverse, simultaneously, owing between various types, operating mechanism component universality is poor, thus add manufacture, assemble, safeguard and use cost.Therefore, it is necessary to develop a kind of compact conformation, facilitate the tractor self shifter power take-off mechanism that complete machine is arranged, component universality is high, it is possible to decrease manufacture, assemble, safeguard and use cost, facilitate operator, alleviate driver's labor intensity.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, facilitate the wheeled tractor self shifter power take-off mechanism that complete machine is arranged, component universality is high, facilitates tractor dynamic power to export gear shift operation.
The technical solution of the utility model is: wheeled tractor self shifter power take-off mechanism, including: U-shaped bar of shifting gears, driven shaft back-up ring, shifting sleeve return spring, 540 revs/min of driven gears, U-shaped bar return spring of shifting gears, shifting sleeve, gearshift finger, engaging sleeve, 1000 revs/min of driven gears, power output shaft head, power output driven shaft, power output housings；It is adjacent to be sleeved on power output driven shaft by 540 revs/min of driven gears and 1000 revs/min of driven gears, the spline on gear and engaging sleeve engagement；Gearshift finger one end is inserted in engaging sleeve, and the other end inserts in shifting sleeve, and shifting sleeve inserts power output driven shaft and can slide axially, and power output shaft head inserts power output driven shaft from the other end and connects with spline；Driven shaft shield ring sleeve is contained in power output driven shaft, and shifting sleeve return spring is arranged between driven shaft back-up ring and shifting sleeve；Shifting gears in U-shaped bar one end insertion shifting sleeve, the other end inserts in power output housing, and U-shaped bar return spring of shifting gears is sleeved on the U-shaped bar of gearshift, and its two ends are adjacent on the boss of power output housing.
This utility model can reach following beneficial effect after using technique scheme: uses this utility model for the PTO of two gears, directly can switch between two gears by changing spindle nose, and power difference tractor spindle nose is generally applicable, this utility model device is easy to use and reliable, low cost, part universality is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model wheeled tractor self shifter power take-off mechanism.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.As shown in Figure 1, wheeled tractor self shifter power take-off mechanism, including: U-shaped bar 1 of shifting gears, driven shaft back-up ring 2,3,540 revs/min of driven gears 4 of shifting sleeve return spring, U-shaped bar return spring 5 of shifting gears, shifting sleeve 6, gearshift finger 7,8,1000 revs/min of driven gears 9 of engaging sleeve, power output shaft head 10, power output driven shaft 11, power output housing 12.540 revs/min of driven gears 4 and 1000 revs/min of driven gears 9 are sleeved on power output driven shaft 11, the spline of two gears is adjacent to, engaging sleeve 8 is connected on 540 revs/min of driven gears 4 and 1000 revs/min of driven gears 9 by spline housing, can mount with the spline on 540 revs/min of driven gears 4 or 1000 revs/min of driven gears 9 when horizontally slipping, gearshift finger 7 one end is inserted in engaging sleeve 8, the other end inserts in shifting sleeve 6, when shifting sleeve 6 moves left and right, gearshift finger 7 can be driven to move, so that engaging sleeve 8 moves, it is achieved gearshift.Shifting sleeve 6 inserts power output driven shaft 11, can slide axially；Power output shaft head 10 inserts power output driven shaft 11 from the other end, connects with spline, and power output shaft head 10 two ends are respectively adopted 540 revs/min and the spline of 1000 revs/min；Driven shaft back-up ring 2 is sleeved in power output driven shaft 11, and shifting sleeve return spring 3 is arranged between driven shaft back-up ring 2 and shifting sleeve 6；Shifting sleeve 6 is inserted in U-shaped bar 1 one end of shifting gears, and the other end inserts in power output housing 12, and U-shaped bar return spring 5 of shifting gears is enclosed within the U-shaped bar 1 of gearshift, and its two ends are adjacent on the boss of power output housing 12.
As shown in Figure 1, when using 1000 revs/min of power output shaft head 10, owing to the other end of spindle nose is porose, under the effect of shifting sleeve return spring 3 spring force, the boss of shifting sleeve 6 inserts in the hole of power output shaft head 10, drive gearshift finger 7 to move to right, stir engaging sleeve 8 and move right, mount 1000 revs/min of driven gears 9.
When using 540 revs/min of power output shaft head 10, owing to the other end of spindle nose does not has hole, plane promotes shifting sleeve 6 to be moved to the left, gearshift finger 7 is driven to move to left, stir engaging sleeve 8 to be moved to the left, mount 540 revs/min of driven gears 4, it is achieved from the switching of 540 revs/min to 1000 revs/min.
In sum, this utility model can switch at two gears by changing spindle nose.This utility model device is easy to use and reliable, low cost, and part universality is high.
