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.

A dynamic model of the transmission brake-single face-dog clutch system is developed and the engagement probability map characterizing the engagement capability of face-dog clutches under different engagement conditions is determined through numerical simulations for different gears of a given AMT. A region of engagement conditions is recognized where the engagement of the face-dog clutch is not ensured. Parameters influencing that region are highlighted. Optimal engagement conditions providing major gearshift comfort are given for the cases of stopped and moving vehicles. Simulation results are partly validated through statistical evaluation of measurement data obtained from a series of measurements performed on a gearbox test bench.

A multi-disk transmission brake is installed to brake down gearbox shafts at upshifts. The goal of this paper is to develop the dynamic model of an electro-pneumatic countershaft brake including parameter identification and model validation.

Features like external engine control, auxiliary engine brake and countershaft brake for external synchronization are introduced to minimize the length of torque interruption during the gear shifting process. This paper first highlights the possibility and advantages of using dog clutches instead of synchromesh mechanisms. A short analysis of the engagement process is given based on measurements, with respect to the speed difference at the moment of engagement, showing the existence of an optimal speed difference. As a main topic, the external synchronization is described. Strategies for synchronization are developed for stopped, moving and slowly moving vehicle. Restrictions for the reachable speed differences are given, showing that the low idle speed of the engine, the inner ratios of the gearbox and the possible speed differences are not independent from each other.

Most of the racers use hungarian made single cylinder Pannonia motorbike. The racers complain of the slow shiftability of the gearbox. Sidecar drivers complain of inappropriate distribution of the gear speeds. New parts for these old gearboxes do not exist. Thus, a need exists for improving them. Instead of refabricating the old gearbox parts and keeping the shifting and gear distribution problems, a new gearbox design is proposed. It has more gear speeds and it fits in the original engine block without any transformation. The shiftability and gear speed distribution is improved. The state of the work is presented.
