Downsizing of a Constant Mesh Gearbox by Introducing Power Flow Technique with an Electro-Hydraulic Control System

摘要

The constant mesh gearbox is the most adoptable transmission unit that is available in the current automotive market today because of the simple gear train design. This design features a driver operated clutch and a movable gear stick. Most automobile transmissions allow the driver to select different gear ratios at any time. But with the increased demand in the number of gear ratios for increased torque and speed, transmission unit is getting bigger and controlling them has become more complex. This paper identifies a new way of power flow in the gear box, resulting in availing more numbers of gear ratios with less number of gears from the existing unit. This paper also suggests the development of a electronic control system for the shifting of the gears for smooth operations.
