Abstract

The invention relates to a flat hydraulic torque converter without an inner ring for a saloon car. A pump pulley, a turbine and a guide wheel are structurally provided with no inner ring; the loop circle of the torque converter is of a flat elliptical shape; the elliptical width W is 0.18-0.21 times of the effective diameter D of the torque converter; the blade of the pump pulley is a space twisted blade, the working face thereof is a space curved surface consisting of an outer-ring space curve and an entrance edge and an exit edge which are straight lines; and the turbine blade is a space twisted blade, and the working face thereof is a space curved surface consisting of an outer-ring space curve and an entrance edge and an exit edge which are straight lines. Compared with the existing flat hydraulic torque converter with the inner ring, the invention is characterized in that K0 is increased to 2.171 from 1.8; and the nominal torque is increased to 15.737N from 14.78N. Since the torque converter inner ring is removed, the loop circle is still flat, the start torque-variable ratio and efficiency of the torque converter are improved, power consumption is reduced, and energy resources are saved. The invention adopts smaller effective diameter to meet the matching requirement of an engine with the same power, solves the problem that the arrangement space of a precursor transmission system is limited, improves the performances, and reduces energy consumption.

Description

Technical field: [0001] The invention relates to a car automatic transmission, in particular to a car flattened non-inner ring hydraulic torque converter with space warped blades. Background technique: [0002] The hydraulic torque converter is one of the key components of the car hydraulic automatic transmission. As a flexible power transmission device, it has the ability of stepless speed change and torque change, which can make the vehicle start smoothly, reduce the impact and improve the life of the drive train, so it is widely used in the car industry. With the overall technical progress of the automobile industry, the design of automobiles is becoming more and more compact, especially at present, most of the cars are front-engine front-wheel drive, and the layout space of the transmission system is small, so it is required to reduce the axial and axial directions of the torque converter accordingly. Radial dimension, the flattening of hydraulic torque converter has be...
