摘要： A fan drive assembly for a vehicle, which can provide reverse fan flow. The assembly has a fan, where separate forward and reverse clutches are coupled to the fan. The reverse clutch has a greater torque capacity than the forward clutch, such that when the reverse clutch is applied, the forward clutch is made to slip, allowing for the reverse rotation and flow of the fan.

摘要： A magnetic slip clutch (26,415) is disclosed, which may be fully uncoupled, fully coupled, or coupled in a modulated manner for transmission of variable torque. One use of the clutch is to provide a variable speed drive of a fan (24,424) having fan blades (20,420) for use with an internal combustion engine (12) such as on a vehicle (10). A torque transfer between a clutch driving element (202,416,616) and a driven element (200,418,618) is by a controller and a circuit (30,70,702,722) that modulates the electrical power to control the magnetic field between the driving element (202,416,616) and the driven element (200,418,618). The preferred driving element (202,416,616) carries electromagnetic coils (300-310,438,638) that are energized to develop a magnetic field for coupling to the driven element (200,418,618) that has magnetic elements preferably in the form of magnetizable pole pieces (260-270,429,629) thereon. The clutch includes an electrical generator (435,601) to generate its electrical power. The generator (435,601) receives a trickle supply of current, and it generates an AC current; and a rectifier (710-720) converts this to DC current for the electromagnetic clutch coils (300-310,438,638). If desired, a commutating system (749,751,722) can be used to provide timed pulses of current to the clutch coils (300-310,438,638) to provide more torque in the direction of clutch rotation.

摘要： Known cooling fans for internal combustion engines designed to prevent an unintentional entrainment of the fan wheel are equipped with braking and locking devices, which imply a corresponding construction of the clutch and hence are relatively complicated. The invention proposes that the fluid friction clutch (6) be combined with a locking device in the form of a swivel hook (15) that can be rigidly mounted with a holding device (7), even as a retrofit, and can be released using an electromagnet (10). This electromagnet (10) can be accommodated in the circuit of the ignition lock (23) so that when the engine is started the fan wheel is prevented from following into unwanted rotation. The invention is used for fluid friction clutches of engine cooling fans.
