A torque converter is a device, ... The equivalent device in a manual transmission is the mechanical clutch. ... Lock-up torque converters
Many TCUs now have an input from the vehicle's traction control system. If the TCS detects unfavourable road conditions, a signal is sent to the TCU. The TCU can modify shift programmes by upshifting early, eliminating the torque converter lock-up clutch application, and also eliminating the first gear totally and pulling off in 2nd. [4]
An over-torque condition pushes the balls out of their detents, thereby decoupling the shaft. It can have single or multiple detent positions, or a snap acting spring which requires a manual reset. There may be a compression adjustment to adjust the torque limit. Many cordless drills incorporate this type of torque limiter in a planetary ...
In the early 1950s, BorgWarner developed a series of three-speed torque converter automatics for car manufacturers such as American Motors, Ford and Studebaker. Chrysler was late in developing its own true automatic, introducing the two-speed torque converter PowerFlite in 1953, and the three-speed TorqueFlite in 1956. The latter was the first ...
The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. This is a fundamental difference compared with a typical hydraulic automatic transmission, which uses an epicyclic (planetary) design, and a hydraulic torque converter.
The 5G-Tronic (model W5A 330 and W5A 580 · type 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lock-up (typically in gears 3, 4 and 5) and 2-speed for reverse.
By historical context of comparison, the '50 Packard Ultramatic which was a torque converter applied two speed lock-up design with high and low range for four forward speeds and the '50 Studebaker/Detroit Gear featured a lock-up torque converter with three forward speeds. The lock-up feature of Packard's Ultramatic and Studebaker's DG 250 is ...
The standard Fluid Drive configuration consisted of the fluid coupling and a manual transmission and clutch in tandem. If the Fluid Drive was mated to a manual transmission, the driver still needed to use the clutch to shift between any of the gears. The presence of Fluid Drive, however, prevented the driver stalling when taking off from a dead ...
