Embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 4, a kind of fluid torque-converter with power taking structure provided by the utility model, including torque-converters
Housing 21 and pump impeller 22, turbine 23, guide wheel 24, power take-off gear 25, main drive gear 26, guide wheel in converter cover 21
It is seat 27, output shaft 28, guide wheel seat ring 29, hubcap 30, oil return pump driver gear 31, scavenge oil pump 32, flywheel 33, shaft coupling 34, soft
Property disk mounting seat 35 and flexible disk 36, this fluid torque-converter are connected by flexible disk 36 with flywheel 33 come passing power, flexible disk
36 are connected with hubcap 30 again by flexible disk mounting seat 35, and hubcap 30 is connected further through bolt with pump impeller 22, by the dynamic of engine
Power passes to pump impeller 22, and main drive gear 26 is arranged on the rear end of pump impeller 22, and main drive gear 26 is engaged power by gear
Power take-off gear 25 is passed to, realizes oil pump power taking, main drive gear 26 drives oil return pump driver gear 31 by engaged transmission
Operating, so as to drive scavenge oil pump 32 to work again, the internal drainage liquid in fluid torque-converter is expelled to outside fuel tank, pump impeller 22 passes through
Bearing is supported on wheel stand 27, and wheel stand 27 is arranged in housing 21, and one end of wheel stand 27 passes through spline and guide wheel seat ring
29 are connected, and guide wheel 24 is arranged on guide wheel seat ring 29, and output shaft 28 is supported in the endoporus of wheel stand 27 by bearing, output shaft
28 one end is connected by spline with turbine 23, and the other end is connected with shaft coupling 34, the power of coming is transmitted from pump impeller 22, by pushing away
The pressure energy of hydrodynamic force feed and the change of kinetic energy, promote turbine 23 to rotate, realize that power is delivered to output shaft 28 from turbine 23, most
Power is passed by shaft coupling 34 afterwards, the conversion of energy is realized and transmits work.
Because existing bell housing seam size is φ 511.17mm, and fluid torque-converter housing seam size is φ 650mm,
Therefore, fluid torque-converter can not be joined directly together with bell housing, and the structure of bell housing mainly includes as shown in Figure 2：Flywheel shell
41st, idle pulley 42, bearing 43, transfer case travelling gear 44 and lid 45, but due in hydraulic system of bulldozer, exist speed change oil circuit and
Working oil path so also needs to install a transfer case, the structure of transfer case is shown in Fig. 3 institutes, it is necessary to 2 oil pumps of engine driving
Show, mainly include：Bell housing 51, transfer casing 52, driven pulley 53, transfer-case cover 54, main shaft 55, driving wheel 56 and lid 57, it is former
Outer gasoline pump just constitutes an independent hydrodynamic system again for fluid torque-converter, bell housing, transfer case, but this system
Very complicated, number of parts is more, and each part matching relationship is complicated, if machining accuracy is beaten less than regulation requirement when mounted, can lead
Cause machine heating, bearing is easily damaged, and the life-span is shorter, and reliability is not high, on the other hand, this complicated structure, cost also compared with
It is high.
In order to which idle pulley 42 and transfer case travelling gear 44 are put into converter cover 21, while again by transfer case driving cog
Wheel 44 is put into torque-converters, it is necessary to improve the shape and size of converter cover 21, and 2 power takings are arranged on converter cover 21
Structure, to install 2 oil pumps.It is φ in bell housing seam size in order to which torque-converters is directly installed on engine flywheel
511.17mm, the pump impeller 22 and hubcap 30 for being easy to torque-converters can be fit into converter cover 21, so torque-converters
Housing 21 is used for the supporter for installing torque-converters each several part part, and a transition connection shell is connected on converter cover 21
Body 37, for connecting engine flywheel.
Power taking structure of the present utility model is to share a converter cover 21 with torque-converters, by pump impeller 22
Main drive gear 26 impart power to power take-off gear 25 and oil return pump driver gear 31 so that of the present utility model take
Power structure greatly simplifies than original structure.
Bell housing just reduces idle pulley 42, transfer case passes using the subsidiary standard bell housing of engine so in flywheel
Moving gear 44 and bearing 43 and the grade part of lid 45.For the flywheel 33 in the utility model, need not be processed in the inner chamber of flywheel 33 interior
Tooth, external diameter need not process external tooth；Reduce transfer case, so so that overall structure greatly simplifies, and number of parts subtracts significantly
Few, weight also mitigates significantly, and processing technology is also greatly improved, and assembly of hydraulic torque converter assembling is simple, torque-converters installation
Also it is relatively simple on bell housing, fast.It is directly installed on bell housing, increases for the ease of fluid torque-converter in the utility model
A transition connection housing 37 is added, torque converter assemblage is connected with flywheel 19 is changed to flexible disk connection by gear connecting way, can
