But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets. [1] [2] Names for specific types of semi-automatic transmissions include clutchless manual, [3] auto-manual, [4] [5] auto-clutch manual, [6] [7] and paddle-shift transmissions.
Although not strictly a part of classic torque converter design, many automotive converters include a lock-up clutch to improve cruising power transmission efficiency and reduce heat. The application of the clutch locks the turbine to the impeller, causing all power transmission to be mechanical, thus eliminating losses associated with fluid drive.
Haldex Traction is a manufacturer of intelligent all-wheel drive (AWD) systems, founded in Sweden.Since the invention of Gen I in 1998, the company produced several generations of products licensed to and customized for some major automotive brands, that in turn have marketed Haldex Traction AWD under different names.
With the clutch off, so the shaft does not spin, the idlers in the two differentials are fixed in place. This is just like the controlled differential with the brake on. When the steering clutch is engaged, the shaft spins one of the idler sets forward and the other backward, causing one track to speed up and the other to slow down. [2]
The T-5 is available in "World Class" (WC) and "Standard" (STD) models; STD are sometimes known as Non-World Class (NWC). Compared to the Standard, the WC changes bearing types and blocker ring materials. [3]
One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.

The Ford N-series tractor helped revolutionize modern mechanized agriculture with its Ferguson three point hitch. A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction.
