Face dog clutch engagement at low mismatch speed

Abstract

Face dog clutches regain popularity in heavy duty AMT's. Though the reduction of the speed difference between the dogs is the key to a smooth gear shift, the excellent engaging capability is experienced to degrade at low mismatch speed and the outcome of the engagement process becomes uncertain. Using a simple mechanical model, that uncertainty is described and the probability of the successful engagement is given as a function of the initial mismatch speed. Results are validated through statistical evaluation of measurement data. © Periodica Polytechnica 2010.
