The purpose of this utility model is to provide a kind of compact conformation, it is light to operate, the load-commutated driving device of trac..
The technical solution of the utility model is: the load-commutated driving device of trac., comprising: load-commutated device, main transformer speed variator, secondary speed-changing device; Load-commutated device, main transformer speed variator, secondary speed-changing device are arranged in order, and wherein load-commutated device one end is connected with driving engine, and the other end is connected with main transformer speed variator.
Input shaft, commutation driven gear shaft and reverse idler gear axle are installed in load-commutated device; Main shift driving shaft is installed in main transformer speed variator, and wherein the axle center of input shaft, main shift driving shaft is on same straight line, and power output front axle passes from the inside of main shift driving shaft.
On input shaft, empty set is provided with commutation driving gear, is installed with forward clutch and the power-transfer clutch that falls back, and commutation one-level driven gear and commutation secondary driving gear are an entirety with commutation driven gear shaft, and reverse idler gear and reverse idler gear axle are an entirety; Reverse idler gear often engages with commutation driving gear, commutation one-level driven gear respectively, and commutation secondary driving gear is intermeshing with commutation secondary driven gear, and commutation secondary driven gear is fixedly installed on main shift driving shaft.
The utility model can reach following good effect after adopting technique scheme: load-commutated driving device adopts above-mentioned arrangement, and compact conformation can be by tractor engine power to trac. main-gear box, auxiliary gearbox and power take-off shaft transmission.Load-commutated Plant arrangement is at main transformer speed front end, and adopts liquid clutch structure to realize commutation to put into gear, needn't stop and put into gear, gearshift impact and gear shifting force little, the gearshift time is few, operating efficiency is high, greatly improves user's operation comfort.
Brief description of the drawings
Fig. 1 is the structural representation of the load-commutated driving device of the utility model trac..
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.As shown in Figure 1, the total load-commutated device T1 of this change speed gear box, main transformer speed variator E, secondary speed-changing device G totally three part compositions.Wherein load-commutated device T1 one end is connected with driving engine A, and the other end is connected with main transformer speed variator E.
Input shaft S1, commutation driven gear shaft S3, reverse idler gear axle S2 are installed in load-commutated device T1; Wherein the axle center of master clutch axle S1 and main shift driving shaft S4 is on same straight line, and power output front axle S5 passes from the inside of main shift driving shaft S4.
In load-commutated device T1, the upper empty set of input shaft S1 is provided with commutation driving gear 1, be installed with forward clutch F and the power-transfer clutch R that falls back, commutation one-level driven gear 4 and commutation secondary driving gear 5 are an entirety with commutation driven gear shaft S3, and reverse idler gear 3 is an entirety with reverse idler gear axle S2; Reverse idler gear 3 is intermeshing with commutation driving gear 1, commutation one-level driven gear 4 respectively, and commutation secondary driving gear 5 is intermeshing with commutation secondary driven gear 2, and commutation secondary driven gear 2 is fixedly installed on main shift driving shaft S4; Forward clutch F separates by hydraulic oil and controls respectively with the combination of the power-transfer clutch R that falls back, in the time that hydraulic oil enters forward clutch F, forward clutch F and 2 combinations of commutation secondary driven gear, when hydraulic oil enters while falling back power-transfer clutch R, fall back power-transfer clutch R and commutation driving gear 1 combination, while disconnecting hydraulic oil, forward clutch F separates.
In tractors reversing arrangement change speed gear box, engine power divides two-way transmission:
The first via is passed to power take-off implement B from driving engine A by input shaft S1, power output front axle S5, drives power take-off shaft.
The second road is passed to load-commutated device T1 from driving engine A by input shaft S1, according to the forward clutch F in load-commutated device T1 and the state of the power-transfer clutch R that falls back, can realize two gears, and the bang path of each gear is as follows:
Forward gear: hydraulic oil enters forward clutch F and disconnect simultaneously the hydraulic oil of the power-transfer clutch R that falls back, forward clutch F and 2 combinations of commutation secondary driven gear, the power-transfer clutch R that falls back separates.Power is by input shaft S1 → forward clutch F → commutation secondary driven gear 2.
Gear falls back: hydraulic oil enters the power-transfer clutch R that falls back and disconnect simultaneously the hydraulic oil of forward clutch F, fall back power-transfer clutch R and 1 combination of commutation driving gear, and forward clutch F separates.Power is by the input shaft S1 → power-transfer clutch R → commutation driving gear 1 → reverse idler gear 3 that falls back → commutation one-level driven gear 4 → commutation secondary driving gear 5 → commutation secondary driven gear 2.
Power is by secondary driven gear 2 → main transformer speed variator → secondary speed-changing device → back axle D/ propons C that commutates.
The load-commutated device of this trac. can be realized trac. in the time of commutation, needn't stop and can realize commutation operation, and commutation steadily, and simple to operate, impulsive force is little, greatly improves user's operation comfort, improves operating efficiency.
