  • Motor vehicle change-speed gearbox
    Patent number: 5351569
    Abstract: A change-speed gearbox is arranged such that two gear stages (constant mesh gears) are used between an input shaft and a parallel countershaft, and one gear stage is used between the countershaft and a parallel output shaft. A gearbox range with at least three gearbox types with different permissible input torques is obtainable in that two of the three gear stages have a step-up transmission ratio so that the total transmission ratio becomes lower from gearbox type to gearbox type as the input torque increases.
