Abstract:
A coupling device system for use in a motor vehicle is provided including a coupling device and a memory chip. The coupling device has an input member, an output member, and at least one modulating clutch assembly selectively coupling the input member to the output member. The modulating clutch assembly includes an electrical clutch operator and clutch plates. The clutch plates include at least one first clutch plate coupled to the input member and at least one second clutch plate coupled to the output member. The second clutch plate is disposed adjacent the first clutch plate. The memory chip is integrated with the coupling device and is configured to store data related to a measured characteristic of the coupling device. The memory chip is also configured to communicate with a vehicle controller. A method of providing a calibration curve of the coupling device to the vehicle controller is also disclosed.

Abstract:
The present invention relates to a motive power device for a vehicle, which is preferably retrofittable as front or rear axle. In a first embodiment, the device comprises a chassis (301) supporting at least one electric motor (318) and attached to the vehicle suspension fixtures with mounts (302, 304). Wheel hubs (377) are suspended from the chassis (301) and driven by the at least one motor (318). Further independent claims are included for a motive power device having a controller providing launch assist and/or stability control, a motive power device having at least two motors and a clutch therebetween, a vehicle provided with these various motive power devices, a method of making a vehicle, a clutch per se and an acceleration controller.
Abstract:
An offset setting method comprising step S101 for making a decision whether the wheel speeds of front and rear wheels are 0 km/h or not, step S105 for making a decision whether the stepping amount of an accelerator pedal is 0% or not, and step S113 for setting a current detection signal voltage Vi at that point in time as an offset voltage Vof if a decision is made that the stepping amount of the accelerator pedal is 0%. Since the offset voltage level Vof is reset when these conditions are satisfied, control accuracy is prevented from lowering due to an error caused by temperature drift, or the like, by setting the offset voltage level Vof while including such an error component.
Abstract:
An epicyclic gear train (3, 4, 7) acts as a speed reducer gear between an input (1) and an output (2) when a clutch (14, 15) is released, and is in direct drive when the clutch is engaged. Selective engagement is provided by means of centrifugal fly weights (31) acting against return springs (29), and by the reaction of helical teeth (FAC), proportional to the torque transmitted during operation as a reducer gear. The reaction (FAC) stabilises the transmission ratio used and assists operation as a reducer gear when the torque to be transmitted is high. Means (120) are provided for applying an impulsional force to the flyweights (31) when the driver depresses the accelerator pedal (132). A pole face (127) of an electromagnet (123, 124, 126) then draws the flyweights in the direction corresponding to the release of the clutch to initiate and accelerate, if necessary, a return to operation as a reducer gear. For use in motor vehicles.
Abstract:
An electric propulsion module supplements may be added to pre-existing vehicles to upgrade them or may be used as a component for new designs of all- electric or hybrid vehicles. In an embodiment, the electric propulsion module forms a self-supporting unit that includes two motors, controllers, and electric power components which can be attached to the suspension fixtures of a vehicle. In a particular embodiment, torque can be selectively transferred between the motors by an electromagnetic clutch.
Abstract:
A coupling device for coupling rotatable bodies together that includes first and second rotatable bodies (1, 3 or 1, 5), a plurality of coupling members (19, 21, 28, 30) for selectively coupling the first and second rotatable bodies together to transfer drive between the rotatable bodies, and electro-magnetic actuator means (26) for controlling engagement of the coupling members. The invention also relates to a transmission system including the coupling device. The transmission system includes first and second drive shafts (1, 7), first and second gear sets (15, 17) mounted on the shafts for transferring drive between the shafts, each gear set including a first gear wheel (3, 5) mounted on the first shaft (1) for rotation relative to the first shaft said first gear wheel having a plurality of drive formations (19, 21), and a second. gear (9, 11) mounted on the second shaft (7) for rotation with the second shaft, selector means (13) for selectively transferring drive between the first shaft and either the first or second gear set including a plurality of engagement members (28, 30) for engaging the drive formations (19, 21), and electro -magnetic actuator means (26) for controlling engagement of the engagement members and the drive formations.
