Hydraulic torque converter for motor vehicle, has impeller and turbine including trailing edges remote from axial distances of leading edges of turbine and reactor, respectively, where ratio between distances is equal to one

摘要

#CMT# #/CMT# The converter has an impeller, a turbine and a coaxial reactor including an impeller blade (1), turbine blade (2) and a reactor blade (3), respectively. The blades are respectively delimited by inner lateral edges (11, 21, 31), outer lateral edges (12, 22, 32), trailing edges (13, 23, 33) and leading edges (14, 24, 34). The trailing edge of the impeller is remote from an axial distance (d1) of the leading edge of the turbine. The trailing edge of the turbine is remote from axial distance (d2) of the leading edge of the reactor, where the ratio between d2 and d1 is equal to 1. #CMT#USE : #/CMT# Hydraulic torque converter for an automatic transmission (claimed) in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The ratio between the axial distances is equal to 1, thus permitting to increase the torque capacity of the converter, while maintaining satisfactory torque ratio. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a part of a hydraulic torque converter.
