As shown in the above, if adopt existing torque-converters drive mechanism form, because the bonding sites of guide wheel roller race and lining and guide wheel, turbine are identical with the axial position of pump impeller, in order to the needs of the certain power of satisfied transmission motor and rotating speed, in pump impeller, turbine, the unalterable situation of Guiding wheel structure size, the diameter of turbine output shaft can only be reduced or ensure the size needed for turbine output shaft by the wall thickness reducing guide wheel roller race and lining.There is the problem of rigidity, resistance to torsion difference in the turbine output shaft after reduced, in some cases, after turning round as increased through torque-converters, output torque improves several times compared to crank torque, because turbine output shaft diameter is very little, can not bear too high moment of torsion, if the moment of torsion increased has exceeded the scope that turbine output shaft can carry, meeting has very easily caused turbine output shaft to be out of shape or fracture due to turbine output shaft rigidity, resistance to torsion difference; The wall thickness reducing guide wheel roller race and lining then can reduce guide wheel roller race and lining intensity, affects stability and the working life of product use, and there is larger potential safety hazard.
Model utility content
The utility model aims to provide a kind of structure improving transformer turbine output shaft rigidity and resistance to torsion, to solve defect existing in existing fluid torque converter, namely because turbine output shaft is by the restriction of associated components radial dimension, turbine output shaft size is made to reduce the problem of caused rigidity, resistance to torsion difference.
The utility model is achieved by following technical solution:
A kind of structure improving transformer turbine output shaft rigidity and resistance to torsion, comprise housing, lining, turbine output shaft, pump impeller, turbine, guide wheel and overrunning clutch, turbine output shaft is placed in housing central section, and pump impeller, turbine, guide wheel and overrunning clutch are all socketed on turbine output shaft; Described overrunning clutch comprises the freewheel outer ring, guide wheel roller and the fixed guide wheel roller race that are fixedly connected with guide wheel; The cross section of described guide wheel roller race is " convex " font, described freewheel outer ring and guide wheel roller are all arranged on the left of guide wheel roller race, described lining to be arranged on the right side of guide wheel roller race and to be fixedly connected with by splined member, and guide wheel roller race right-hand member is connected to lock-nut by external thread rotary.
