  • Gear-shift mechanism for motor-vehicle multi-step transmissions with interruption of traction
    Patent number: 4817470
    Abstract: A gear-shift mechanism for motor-vehicle multi-step transmissions with interruption of traction is designed in the manner of a semi-automatic transmission. Manual control switched 80, 81 connected to a control unit 82 serve to actuate shift forks via servo systems 90. Sensors coact with rotating marks on the power take-off shaft and with marks on the speed gears which are driven by the drive shaft. The relative phase position .phi. between the speed gears and the gearshift sleeves driven by the power take-off shaft is determined by a phase detector 75. When a pre-determined phase position is reached, these elements are brought into engagement with each other.
