Abstract
A hydrokinetic torque converter with a housing (23, 26) connected to an internal combustion engine; a turbine (21); and a bridge coupling or lock-up clutch (45) which has a plurality of friction linings (1, 7; 31, 39, 40; 54, 57) that can be brought in a predeterminable order and independent of one another into active connection with a particular associated friction surface for establishing a frictional connection between the housing (26) and the turbine wheel (21). Under pressure the converter bridge coupling acts initially as a single-surface and later as a double-surface converter coupling. In addition, the bridge coupling can have a low transmission capacity per pressure unit in the low pressure range and the transmission capacity can be increased disproportionately starting at a certain pressure range.
