| This dissertation focus on designing a wedge-based rotating clutchactuator for stepped automatic transmission. Compared with traditionalhydraulic clutch actuator, rotating wedge clutch actuator has some uniquefeatures. The complex oil channels, valves, accumulators and pump areremoved so that the energy supplied by engine can be saved; Driven bymotor, rotating wedge clutch actuator can be precisely controlled. This alsomeet the current trend of electrolyzed system in auto; Rotating wedge clutchhas self–reinforcement effect which can magnify the input force and get arelative high normal force.The main contents of this dissertation consists structure design,dynamic modelling and open loop control in clutch shift. Structure designmainly focus on introducing the ideas of design, mechanical structure andmechanism principles. Dynamic modelling can validate the feasibility ofthis structure and analyze the impact of some crucial parameter. As for theopen-loop control while shifting, basic modelling and simulation results canplay a positive role in further research.Equivalent model is built in mathematical modelling and thesimulation is based on matlab-simulink environment. From the simulationresults, rotating wedge clutch actuator can realize preconceived function,response fast and have self-reinforcement effect. This pose a positive impacton electromotoric actuators. Rotating wedge clutch actuator have apromising future and can apply in other transmissions as well. |
