Abstract
Pulley assemblies for vehicle accessories, such as a water pump. The pulley assembly which can be connected to a related housing member, such as a clutch housing member, includes a pulley member directly driven by the accessory belt of a vehicle engine and a separate pair of bearing members. A preferred use of the pulley assembly is with a hybrid coolant pump with two modes of operation, an electric motor operation, and a mechanical pulley-driven operation. A friction clutch assembly can be positioned inside the housing member and can include a softening spring which minimizes parasitic clutch power consumption.
