摘要： A less expensive and less bulky motor vehicle performance test apparatus is disclosed which conducts various tests of a motor vehicle, such as a running test of a four-wheel drive vehicle and an evaluation test of a viscous coupling of a four-wheel drive vehicle, The apparatus comprises a synchronizer including a belt drive whereby the peripheral speed of rollers of a front wheel roller assembly is equalized with the peripheral speed of rollers of a rear wheel roller assembly, eddy-current dynamometers fixedly coupled with the front and rear wheel roller assemblies, respectively. An electromagnetic clutch is arranged to interrupt the drive connection by the synchronizer. The electromagnetic clutch is engaged to conduct a running test of a vehicle under test. The clutch is disengaged and excitation current is introduced to at least one of eddy-current dynamometers to conduct an evaluation test of a viscous coupling of a four-wheel drive vehicle.
