System in manual transmission for reducing required manual force during N-R shifting

摘要

The gearbox system has a device that generates a braking force on a drive shaft during a neutral to reverse change and a neutral to reverse change detector switch that passes a signal to the braking force generator at the start of a neutral to reverse change process. The braking force generator has a frictional element acting on the outer surface of the drive shaft under control of a drive depending on neutral to reverse detector circuit signals. The gearbox system has a braking force generator (3) that generates a braking force acting on a drive shaft (1) during a change from neutral to reverse and a neutral to reverse change detector switch (5) that passes a signal to the braking force generator at the start of the neutral to reverse change process. The braking force generator has a frictional element (7) acting on the outer surface of the drive shaft under control of a drive (9) depending on the signals from the neutral to reverse detector circuit.
