Gear levers and pedals constitute the primary mechanical interface between the driver and the vehicle’s transmission and drivetrain. Gear levers, located within the cabin, mechanically select desired gear ratios via linkage or cables connected to the transmission. Pedals – typically throttle, brake, and clutch – translate foot pressure into mechanical or electronic signals controlling engine power and vehicle deceleration/stopping. Modern systems increasingly utilize fly-by-wire technology, replacing direct mechanical linkages with electronic sensors and actuators. Key features include precise engagement mechanisms, durable materials resisting wear, and increasingly, integrated position sensors for transmission control units. Proper function is critical for safe vehicle operation and efficient power transfer.
