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
It is meshed.Therefore, the revolving force of input shaft 110 is transferred to power shift axle 210 with high speed or low speed.

Turn to rotate the main transformer being connected speed jackshaft 310.Constitute the main transformer speed jackshaft 310 and main variable speed shaft of main transformer speed variator 300
320 can be exported transformation of speed into four stages.That is, if optionally making to be arranged at four of main transformer speed jackshaft 310
One of gear transmits power with the mode that one of 4 gears for being arranged at main variable speed shaft 320 are combined, then can be substantially real
Existing four step changes.
Referring next to Fig. 3, pair power related to secondary speed-changing device 400 transmission is illustrated.Above-mentioned main variable speed shaft 320
Rotation is transmitted by multiple gears to secondary speed change jackshaft 420.And, the rotation of secondary speed change jackshaft 420 is transferred to can be described as
The backgear 410 of secondary variable-speed shaft, and the speed change in four stages is realized again.
High speed, low speed, middling speed are capable of achieving in secondary speed-changing device 400 and four stages creeped etc. of Ultra-Low Speed are can be described as
Speed change.As described above, in the power of secondary speed change jackshaft 420 is transferred to, by optionally making to be arranged in the middle of secondary speed change
One of four gears of axle 420 and be arranged at one of four gears of backgear 410 be meshed it is dynamic to the transmission of backgear 410
Power.
And understand, the power of secondary speed change jackshaft 420 is according to the speed transmission selected in the gear shift stage in four stages
To backgear 410.Backgear 410 transmits basic motive by differential gear 500 to the trailing wheel of tractor.And, this rear tooth
The revolving force of wheel 410 is optionally transferred to front-wheel drive 700, so as to can be at the state of four-wheel drive.Also, on
The power for stating secondary speed change jackshaft 420 flows through PTO drive shafts 610, PTO clutches 640 and PTO speed change gears 620, so that can
It is final to transmit power to PTO shaft 630.
With reference to the used with tractor speed changer with above-mentioned ordinary construction, the two of power shift clutch 220 can be respectively realized
Four stages ground speed change in four stages and secondary speed-changing device in stage, main transformer speed variator, therefore 32 ranks can be realized on the whole
The speed change of section.But in tractor, in addition to the traveling of main body, in addition it is also necessary to consider many accompanying by being suitable for greatest extent
Plant the speed of the Work machine of species.In fact, in view of the Work machine of various species, the stage of actual travel speed is more
It is more favourable, in fact, in view of required work machine velocity, this is natural.
And, can realize that the structure of each four step change is by machine in above-mentioned main transformer speed variator and secondary speed-changing device
Tool speed change.For example, in four gears of main variable speed shaft and main transformer speed jackshaft are respectively arranged at, by using the behaviour of personnel
Work makes one in four gears to be meshed, and so as to realize gear shift, thus realizes output by the rotating speed of said gear speed change.
