Abstract
A control system is provided for the operation of a fluid torque converter for vehicles comprising a pump wheel connected to an engine output shaft, and a turbine wheel connected to a turbine shaft which is coupled to a driving wheel. A fluid transmits power between the pump wheel and the turbine wheel and a one-way clutch is provided between the engine output shaft and turbine shaft for connecting and disconnecting these shafts to and from each other. The one-way clutch, when in an engaged state, directly couples the engine output shaft and the turbine shaft to transmit power solely from the engine output shaft to the turbine shaft. The one-way clutch is provided with a load capacity control unit adapted to vary the load capacity thereof when the one-way clutch is in an engaged state.
Claims8
A control system for operation of a fluid torque converter for vehicles comprising:
- (a) an engine having an output shaft;
- (b) a pump wheel connected to said output shaft;
- (c) a driving wheel;
- (d) a turbine shaft connected to said driving wheel;
- (e) a turbine wheel connected to said turbine shaft;
- (f) a fluid for transmission of power between said pump wheel and said turbine wheel;
- and
- (g) a one-way clutch means coupled between said output shaft and said turbine shaft for connecting and disconnecting said shafts to and from each other, said one-way clutch means, when engaged, directly connecting said output shaft and said turbine shaft to transmit power from said output shaft to said turbine shaft, said one-way clutch means including:
- a driving member connected to said output shaft and provided with a conical, driving outer circumferential surface,
- a driven member connected to said turbine shaft and provided with a conical, driven inner circumferential surface opposed to said conical driving surface,
- wedge rollers provided between said driving and driven members, and
- means associated with said driving member for engaging and disengaging said driving and driven members with and from each other in response to hydraulic pressure applied thereto.
