Hydraulic torque converter with housing - contains pump wheel, turbine wheel and transition coupling, has two pipes and pressure throttle

摘要

The hydraulic torque-converter (10) has a hydraulic fluid circuit and a housing (11) containing at least one pump wheel (14), a turbine wheel (15) and a transition coupling (12) with slip regulator. The converter housing and its parts are supplied with hydraulic pressure at a set pressure via a first pipe (19). The housing near the transition coupling is fed via a second pipe (20). The transition coupling is opened by feeding hydraulic fluid via the second pipe and closed by removing the hydraulic fluid in an adjustable quantity. The second pipe is fed at the same time with hydraulic fluid at a pressure throttled in relation to the pressure in the system. ADVANTAGE - The transition coupling can be driven in a permanent slip state.
