Abstract
A hydrokinetic torque converter, particularly for use in the power train of a motor vehicle, has a housing which can receive torque from the prime mover of the vehicle and drives a pump adapted to rotate a turbine on the input shaft of the change-speed transmission. The turbine can also receive torque from the housing by way of a bypass clutch and a damper borne by a hub which is mounted on the input shaft. A feature of the invention resides in the simplicity of design and low cost of several component parts of the torque converter and in a novel mode of assembling the component parts.
Claims22
A hydrokinetic torque converter for transmission of torque between a rotary output member of a prime mover and a rotary input member of a transmission, comprising:
- a turbine;
- a damper for the turbine;
- and means for transmitting hydrokinetic energy from said turbine to said input member, including a hub and an additional component of an inner region of a turbine shell, which is free of its own hub and supported by an input element of said damper, said inner region of said turbine shell being furnished with a stamped first collar, said damper including an input element having a second collar, said hub having a cylindrical surface spaced apart from one of said collars and further comprising a thrust bearing disposed between and guided by said hub and said one collar.
A hydrokinetic torque converter for transmission of torque between a rotary output member of a prime mover and a rotary input member of a transmission, comprising:
- a turbine;
- a damper for the turbine;
- and means for transmitting hydrokinetic energy from sad said turbine to said input member, including a hub rotatable with said input member, and an additional component, wherein said damper comprises two annular input elements abutting each other at a substantially right angle and being welded to one another, one of said input elements having a collar rotatably mounted on a periphery of said hub.
