Fig. 1 shows a kind of exemplary machine 100.Machine 100 can be such as Work machine, as wheel loader.Machine 100 also can be perform the operation relevant with specific industry (such as dig up mine, build, agricultural, transport etc.) and at the machine of middle other type any worked of various operating environment (such as mining site, building site, farm and road etc.), such as crawler excavator, wheel grader etc.
Machine 100 can comprise mainframe 30, operator's holding space as operator cabin 35 and working implement 36.In one embodiment, working implement 36 can be the scraper bowl being applied to loader.Machine 100 can comprise at least one and operate with working implement 36 and be connected and be used for controlling the oil cylinder 37 of working implement 36 action.There is traveling gear 40 in the lower disposed of machine 100, be used for supporting and mobile apparatus 100.In one embodiment, traveling gear 40 comprises wheel 41.
Machine 100 shown in Fig. 1 gives such as traveling gear 40 by the transmission of power that the power system by machine exported according to transmission device of the present utility model.Fig. 2 illustrates an embodiment of this transmission device, and it comprises twin-turbine torque converter 1 and speed changer 3 (only part illustrates).
Twin-turbine torque converter 1 connects with the power system (as motor, not shown) of machine and is driven by this power system.Specifically, such as, engine flywheel drives hubcap 12 to rotate by elasticity land 11.Hubcap 12 drives the pump impeller B be connected with it to rotate, pump impeller B drives the work of oil pump (not shown), and then order about fluid at pump impeller B, shuttling movement between two turbines T1, T2 and guide wheel D, make power from the first turbine output shaft 13 be connected with the first turbine T1 and the second turbine output shaft 14 (hollow) output be connected with the second turbine T2.First and second turbine output shafts 13,14 respectively with two to having engaging gear Z1, Z2 and Z3 of different drive ratios, Z4 is connected.Twin-turbine torque converter 1 is equipped with free wheel device 2, and it is arranged between gear Z2 and Z4.When outer load is low, the rotating speed of gear Z4 is higher than the rotating speed of gear Z2, and free wheel device 2 is thrown off automatically, and power is exported via the output shaft 15 be connected with gear Z4 of twin-turbine torque converter 1 by means of only the second turbine T2 and gear Z3, Z4.Along with the increase of outer load, the rotating speed of turbine reduces, make the rotating speed of gear Z4 lower than the rotating speed of gear Z2, so free wheel device 2 engages, thus power jointly to be provided via respective paired engaging gear by first and second turbine T1, T2 and finally exports with the speed reduced through output shaft 15.
The power inputing to twin-turbine torque converter 1 from power system is spin axis with A, calls in the following text " power input shaft line ".This power input shaft line A is also the spin axis of hubcap 12, pump impeller B, the first and second turbine T1, T2, guide wheel D, the first and second turbine output shafts 13,14.Be installed on the state in machine at twin-turbine torque converter 1 under, as shown in Figure 2, its output shaft 15 in the vertical direction is configured in the below of power input shaft line A.
According to the utility model, the output shaft 15 of twin-turbine torque converter 1 can not be provided with the first transmission gear 16 rotatably relative to it, first transmission gear 16 and second transmits gear 17 and engages, and the second transmission gear 17 can not be arranged on a passing shaft 18 with the relative rotation, the rotation of fluid torque converter 1 exports and is sent to passing shaft 18 through the first and second transmission gears 16,17 thus.Here, the first and second gear ratios transmitting gear can be arranged to carry out gearing down, step-up drive or constant speed drive between which as required.Input shaft 4 arranged coaxial of passing shaft 18 and speed changer 3 is also operatively connected each other and passes to speed changer 3 the rotation of twin-turbine torque converter 1 to be exported.Advantageously, as shown in Figure 2, passing shaft 18 directly forms as one with the input shaft 4 of speed changer 3, and in other words, passing shaft 18 is directly used as the input shaft of speed changer 3.Certainly, passing shaft 18 also can not be fixed together with the input shaft 4 of speed changer 3 indirectly with the relative rotation by other mechanism (as coupling).
The power being sent to the input shaft 4 of speed changer 3 by passing shaft 18 exports from speed changer 3 with different velocity ratios via transmission gear 5,6 etc. again.The type of speed changer 3 is unrestricted, can be mechanical changeover type or power gear shifting type, and the latter can comprise again fixed shaft type and planetary etc.
Passing shaft 18 in the vertical direction is configured in the top of the output shaft 15 of fluid torque converter 1, and the vertical distance between them changes by the size adjusting the first and second transmission gears 16,17.Such as, passing shaft 18 can with the power input shaft line A arranged coaxial of twin-turbine torque converter 1, with simplified structure.Certainly, passing shaft 18 also can be configured in the vertical direction higher than power input shaft line A (as shown in Figure 2) or lower than power input shaft line A.
In the utility model, twin-turbine torque converter 1 and speed changer 3 can fit together adjacent to one another and be separated by next door 7.Such as, as shown in Figure 2, next door 7 can form as one with the converter cover and case of transmission being positioned at its both sides.Next door 7 can be used for supporting various axles, the output shaft 15 of such as fluid torque converter and the input shaft 4 of passing shaft 18 or speed changer in fluid torque converter 1 and speed changer 3.Advantageously, first and second transmit the side towards twin-turbine torque converter 1 that gear 16,17 is configured in next door 7, and the side of not face speed changer 3, because compared with case of transmission, the dismounting of converter cover is safeguarded more frequent, and torque-converters side transmission gear 16,17 being configured in next door 7 is also convenient to transmit the disassembling, assembling and replacing etc. of gear more.
industrial applicibility
When machine operation, motor by transmission of power to twin-turbine torque converter 1.Twin-turbine torque converter 1 utilizes free wheel device 2 to produce the rotation output of high and low two kinds of speed via output shaft 15 depending on the size of outer load.This rotation exports the input shaft 4 being passed to speed changer 3 further via the first and second transmission gears 16,17 and passing shaft 18.
