Abstract
An apparatus for a clutchless manual transmission includes a transmission, a drive shaft, and a motor shaft. The transmission includes an input shaft, an output shaft, and an intermediate gear. The input shaft is coupled to an engine shaft to receive power and the output shaft is coupled to the drive shaft to transmit power to a wheel of a vehicle. The input shaft and output shaft are coupled by a plurality of input and output shaft gears. A first synchronizer is coupled to the output shaft to selectively engage a particular output shaft gear, adjusting the speed of the output shaft relative to the input shaft. The motor shaft receives power from a motor and includes a second synchronizer to selectively engage the engine shaft to the drive shaft via the motor shaft. The apparatus can be used to reduce acceleration and turbo lag in hybrid and high-performance vehicles.
