Abstract
They make high demands of gear-boxes for sports cars: short gearshift time; gearshift with minimal interruption of power flow (or without interruption at all); ability to stand peak overloads; significant degree of safety and reliability; optimal transmission ratio. In this paper a formula for determination of gearshift time is derived. Its components take account of form factor of the vehicle, psychomotor data and professionalism of the driver. In this paper different gearbox constructions have been rated by the time of gearshift. They are automated manual gearbox, twin-clutch gearbox and new kinematic scheme of gearbox which provides gearshift for 0.1 seconds.
Keywords:gearshift, gearbox, gearshift time, transmission.
