Abstract: According to a light truck model equipped with power shunt two-gear mixing box, the shifting scheme of the mixing box is matched and analyzed. Through theoretical calculation and actual bench data measurement and other methods, the optimal gear matching scheme of the hybrid box is obtained from the definition of gear matching, the analysis of gear shifting time and gear shifting durability, the analysis of gear shifting time when carrying the vehicle, the dynamic and economic performance of the vehicle, and the needs of other systems during the gear shifting process. Through the calculation and analysis of the optimal gear matching scheme, the hybrid box can meet the needs of customers not only in terms of power and economy, but also in terms of comfort.

Key words: power shunt; shift matching; shift evaluation; performance
