The speed changer of the output of form.But, it is contemplated that it is attached to Work machine of the variform of tractor etc., it is preferable that need
Further there are various output speeds.First, reference picture 1, illustrates to existing tractor speed changer.
As illustrated, common used with tractor speed changer includes:Power reciprocating apparatus 100, receives the revolving force from engine,
May be selected to advance or retreat;And power shift device 200, can select high according to the output selected in above-mentioned power reciprocating apparatus
Speed and low speed.The downstream of above-mentioned power shift device 200 is provided with main transformer speed variator 300, above-mentioned main transformer speed variator 300 can
Exported by 3 stages for the revolving force being delivered to.And, the downstream of above-mentioned main transformer speed variator 300 is provided with pair
Speed change gear 400, above-mentioned secondary speed-changing device 400 can with again by the multistage select in the way of export in main transformer speed variator 300
The rotary speed of decision.
The output of this secondary speed-changing device 400 can be delivered to the tire of tractor and by dynamic by differential gear 500
Power output (PTO, Power Take Off) drive shaft 610, PTO clutches 640, PTO speed change gears 620 are eventually transferred to PTO
Axle 630.And, filled by the front-wheel drive including front wheel driving shaft 710 and front-wheel dog-clutch 720 for four-wheel drive
700 are put, the output of above-mentioned secondary speed-changing device 400 can also transmit power to front-wheel.
Hereinafter, reference picture 2 and Fig. 3, are described in detail to each device.As described in Figure 2, according to advance and retrogressing
The selection of clutch 120, by the forward gear 122 or backward gear that are arranged at the input shaft 110 of power reciprocating apparatus 100
Any one gear in 124 transmits power to power shift axle 210.If for example, selection backward gear 124, by retreat
Jackshaft 130 transmits power to power shift axle 210, wherein, the direction of power is the direction of retreat of tractor.
As described above, by the advance transmitted to input shaft 110 or the power of direction of retreat, the power shift axle of selection
210 are provided with the power shift clutch 220 that high speed or low speed may be selected.According to the operation of user of service, above-mentioned power shift
Clutch 220 may be selected high speed or low speed.According to the operation of this power shift clutch 220, before being arranged at input shaft 110
Enter one of low-speed gear 122 or advance high gear 126 and be arranged at two gears 242, one of 244 of power shift axle 210
