As described above, impelling losses within the torque converter reduce efficiency and generate waste heat. In modern automotive applications, this problem is commonly avoided by use of a lock-up clutch that physically links the impeller and turbine, effectively changing the converter into a purely mechanical coupling. The result is no slippage ...
Saab's Sensonic system was electro-hydraulic, using an electric motor or solenoid connected to a hydraulic clutch actuator, whereas Ferrari's Valeo system was electro-mechanical, using an electric motor or solenoid, connected to the mechanical clutch system. [8] [9] [10] Similar TCU or GCU systems are used in racecars with paddle-shift ...
Automatic clutch plus a torque converter. Used in the Citroën GS and Citroën CX. Originally called Convertisseur in GS models. 1991–1993: Ferrari Valeo: Automatic electro-mechanical clutch. Used in the Ferrari Mondial t. [77] [78] 1992–1998: RUF EKS: Automatic electro-hydraulic clutch. Used in the Ruf BTR [79] and Ruf BTR2. 1993–1998 ...
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
Roto's disadvantage was the 2-3 range or 1-2 gear change because it is not only a huge ratio jump from 2-3 range or 1-2 shift from 2.93 to 1.56, but also there is no fluid slippage in the coupling because the coupling drains (four-tenths of a second) to engage or apply the front clutch and so the trans goes to full mechanical connection.
A fluid coupling or hydraulic coupling is a hydrodynamic or 'hydrokinetic' device used to transmit rotating mechanical power. [1] It has been used in automobile transmissions as an alternative to a mechanical clutch .
The mechanical locks are located on either side of the pneumatic ports. The electrical connections are located below the pneumatic ports and are protected by a cover when disconnected. Several versions are available for different applications, which can only be coupled to each other and not to other couplings, except the FK-15-10 version which ...
A secondary function of this cable is to down-shift ("kick down") to a lower gear when the Throttle Valve is in the full stop position (throttle pedal is fully depressed) and road speed is below a set point regulated by a mechanical governor on the output shaft. The hydraulic control system consists of a valve arrangement and an engine driven pump.
