Abstract
The utility model relates to a double turbine fluid moment changer mainly used for a shovel loader, comprising a one-stage turbine, a two-stage turbine, an idler pulley and a pump impeller. An end face thrust bearing is arranged between the two-stage turbine hub and the idler pulley; an end face thrust bearing and a guard ring are arranged between the pump impeller hub and the idler pullet, wherein one side of the thrust bearing is jointed with the idler pulley and the other side tightly leans against the guard ring which leans against the pump impeller hub, thereby avoiding the contact of the turbine and the end face of the idler pulley, so the pump impeller ball bearing does not bear axial force. The utility model not only improves service life and simplifies installation programs, but also results in that the moment changer is flexible and reliable in operation, and small in the loss of efficiency.
Description
Affiliated technical field
The utility model relates to a kind of twin-turbine torque converter, mainly is applicable to loader.
Background technique
Existing twin-turbine torque converter comprises coaxial mounted successively I and II turbine, guide wheel and pump impeller.Wherein the axial position of I and II turbine is to determine by the spacer of a similar back-up ring, that is: one group of spacer is housed in the annular groove of two-stage turbine hub, when torque-converters and transfer case assembling, when the end face of two-stage turbine axle will just prop up spacer in the precalculated position, could guarantee the tram of I and II turbine.When actual assembled, be earlier torque-converters to be decomposed, the gap between the annular groove end face of actual measurement turbine shaft end face and two-stage turbine hub is prepared spacer according to the gap width of actual measurement, and then the part of torque-converters that decomposes is assembled on the transfer case.So not only bother, but also have a tangible unreliable factor, promptly spacer thickness depends on the actual measurement gap width fully, and this is a random variable.When the gap is very little, spacer is very thin, and the I and II turbine is pushed the axial force of guide wheel to and is all born by spacer, tend to cause the spacer fracture, the I and II turbine is produced move axially and prop up guide wheel, promptly two-stage turbine outer shroud outlet side withstands on together mutual friction mutually with guide wheel outer shroud suction side.This friction not only causes the unnecessary consumption of power, oily temperature rise, and can produce metal fillings and pollute working medium oil, has aggravated machine members, has also influenced the efficient of torque-converters.Another deficiency of existing twin-turbine torque converter is that two ball bearings that support pump impeller usually damage in advance, its reason is: the guide wheel right side of torque-converters props up the ball bearing inner race that supports pump impeller, this bearing outer ring right side is by pump impeller hub shoulder location, and the Internal and external cycle of this bearing in service will be subjected to the effect of the opposite axial force of direction respectively.Because there is error in the axial dimension work in-process of motor and torque-converters parts, when both cumulative error is big, this ball bearing will bear bigger axial force, and cause bearing to damage in advance.
Summary of the invention
Technical problem to be solved in the utility model is to overcome existing deficiency in the prior art, provides a kind of and avoids contacting between turbine and guide wheel end face, and can improve the twin-turbine torque converter of pump impeller ball bearing operating life.
The technological scheme that addresses the above problem is: the twin-turbine torque converter that is provided comprises coaxial mounted successively I and II turbine, guide wheel and pump impeller, and improvements of the present utility model are to be provided with an end face thrust bearing between two-stage turbine hub and guide wheel; Be provided with an end face thrust bearing and guard ring between pump impeller hub and guide wheel, wherein thrust bearing one side and guide wheel are fitted, and opposite side is close to this guard ring, and guard ring leans against again on the pump impeller hub.
The utility model is owing to be provided with an end face thrust bearing between turbine hub and guide wheel, thereby cancelled spacer, so not only can guarantee the accurate location of turbine, make torque-converters flexible operation, reliable, loss in efficiency is little, and needn't decompose transfer case and just can directly install, simplified installation procedure greatly.Owing between pump impeller and guide wheel, be provided with the end face thrust bearing, axial force from turbine and guide wheel is acted on the pump impeller hub by bearing and guard ring, and balance each other with the reverse axial force of pump impeller, and the ball bearing that supports pump impeller only is subjected to radial force, thus improved working life significantly.

Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Fig. 3 is the partial enlarged drawing at B place among Fig. 1.
Embodiment
As Fig. 1～shown in Figure 3: this example has adopted punching press and welding fabrication technology, cover wheel 1, one-level turbine 2, two-stage turbine 3, be contained in guide wheel 4 and the coaxial successively installation of pump impeller 5 on the wheel stand 7, be provided with an end face thrust bearing 9 between two-stage turbine hub 8 and guide wheel 4, its right side can install a ring washer 10 additional; Between pump impeller hub 6 and guide wheel 4, be provided with an end face thrust bearing 11 and guard ring 12, wherein thrust bearing 11 1 sides and guide wheel 4 are fitted, and opposite side is close to guard ring 12, and guard ring leans against again on the pump impeller hub 6, axial force is just born by thrust bearing 11 like this, and 13 on the ball bearing of support pump impeller is subjected to radial force.Above-mentioned two end face thrust bearings 9,11 preferably adopt needle roller end face thrust bearing, not only can make compact structure, and can not change the basic design of original torque-converters.
