Described governing system in this utility model includes: hydraulic pump 35, hydraulic valve 36 and control gear 34, hydraulic pump 35 is respectively equipped with flowline 40 and an oil inlet pipe 39；Hydraulic valve 36 connects hydraulic pump oil-out；Control gear 34 to rotate under the drive of described hydraulic pump 35, and described control gear 34 engages with input gear ring 41.Input gear ring 41 is connected fixing with described governing system, and described input gear ring 41 can rotate under the drive of described governing system.Speed-regulating hydraulic pump 35 engages with the gear ring pinion 43 on input gear ring 41 by controlling gear 34, and the rotating speed of described speed-regulating hydraulic pump 35 can change under the control of hydraulic valve 36, is controlled the rotation of input gear ring 41 by the control wheel 34 on speed-regulating hydraulic pump simultaneously.
The replaceable one-tenth servomotor of described hydraulic pump in this utility model, clutch or pulsometer.
Utility model works principle is as follows:
Power is incoming from power shaft 21, is transferred to the first row star-wheel 25 from input sun gear 22, and the first row star-wheel 25 is transferred to power the first high speed braces 38 and input gear ring 41 simultaneously；Input gear ring 41 is transferred to low-speed gear 23 further through 43 power of gear ring pinion, and low-speed gear 23 is transferred to low-speed output gear 26 further through 24 power of slow-speed shaft, and low-speed output gear 26 is transferred to output gear 31 power again；Meanwhile, the first row star-wheel 25 is delivered to the power of the first high speed braces 38, by high speed shaft 32, it is transferred to the second high speed braces 37, now the power of output gear 31 and the power of the second high speed braces 37 are pooled to the second planetary gear 27 simultaneously, and the second planetary gear 27 is transferred to power on output sun gear 29 again.
The rotation direction of input sun gear and the first high speed braces 38, high speed shaft 32, the second high speed braces 37, the rotation direction of output sun gear 29 is consistent, input gear ring 41 is contrary with the rotation direction of the first high speed braces 38, and output gear 31 is contrary with the rotation direction of the second high speed braces 37.
Output gear 31 is contrary with the rotation direction of the second high speed braces 37, power because transmitting from output gear 31 is the power of low-speed big again, for preventing output gear 31 from driving the second high speed braces 37 to reverse, high speed shaft 32 sets a unilateral bearing 33, unilateral bearing is along power shaft 21, input sun gear 22, the rotation direction one-directional rotation of the first high speed braces 38, locked at other direction.
Power is by output gear 31, time second high speed braces 37 is delivered to the second planetary gear 27, because what output gear 31 transmission came is the power of high pulling torque, again because high-speed bearing 32 is provided with unilateral bearing, and unilateral bearing is locked in the rotation direction of gear ring, now the second high speed braces 37 is just motionless as retainer, output gear 31 drive 27 power of the second planetary gear to be transferred to output sun gear 29.
Hydraulic pump 35, hydraulic valve 36, control gear 34 form speed change system.Controlled the rotation of hydraulic pump 35 by hydraulic valve 36, hydraulic pump controls again the rotation of gear 34, controls gear 34 and engages with gear ring pinion 43, controls the rotation of input gear ring 41.
When speed change, hydraulic valve 36 limiting the rotation of hydraulic pump 35, hydraulic pump 35 limits again the rotation controlling gear 34, controls gear 34 because engaging with gear ring pinion 43, limits the rotation of input gear ring 41.The power of now power shaft 21 input is constant, and input gear ring 41 rotating speed under the drive controlling gear 34 and limited slack-off, therefore power is when being delivered to the first row star-wheel 25 by sun gear 22, because the rotating speed of input gear ring 41 is limited, therefore the first row star-wheel 25 starts along ring gear against rotation, driving the first high speed braces 38 to rotate, the first high speed braces 38 drives again the second high speed braces 37 to rotate by high speed shaft 32 simultaneously.Second high speed braces 37 drives again the second planetary gear 27 to rotate along output gear 31, power is delivered to output sun gear 29 simultaneously, is now equivalent to accelerate.When input gear ring 41 is completely motionless under the restriction controlling gear 34, now by input gear ring 41, low-speed gear 23, slow-speed shaft 24, low speed pinion 26, the low-speed gear group of output gear 31 composition stops not rotating completely, power just drives the first high speed braces 38 to rotate either directly through first planet wheel, first high speed braces 38 drives again high speed shaft 32 to rotate simultaneously, high speed shaft 32 drives again the second high speed braces 37 to rotate, second high speed braces 37 drives again the second planetary gear 27 to rotate along output gear 31, and power is directly delivered to output sun gear 29.
This utility model because be the mode that engaged by gear to transmit power, the shortcoming that therefore the existing buncher of customer service easily skids.The hydraulic control system of practical hydraulic pump hydraulic valve so that speed-change process is more smooth and easy, simply.Volume is little, simple in construction, compact.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
