Vehicle interface challenges on manual transmission application.

Vehicle interface challenges on manual transmission application.

NETO, Demetrio Vettorazzo; BELLATINI, Luiz; PINHO, Alexandre; FALCONE, Paulo

Artigo:

The purpose of this Paper is to emphasize how certain vehicle characteristics that at first look seem unrelated to the Manual Transmission can cause undesirable issues on the Manual Transmission operation, performance and behavior. The Application of a same Manual Transmission on different vehicle design can bring unexpected results. These issues may be caused by Engine & Transmission Mounting stiffness, Suspension characteristics, Driveline Design, Driveline Stiffness, etc. These vehicle systems characteristics can potentially cause or aggravate issues as Transmission Gear Jump Out, Drive Rattle, Clunk Audible Noise and even jeopardize the Manual Transmission Gear Shift and contribute to cause Gear Clashing. Careful integration among systems and sub-systems must be considered. The detailed observation of the learnings acquired in past programs is rather important to prevent issues from happening on the Vehicle Development or Validation phases, reducing Development costs.
