An electric vehicle (1) includes a charging circuit (11), a battery (12) and a driving electric motor (13), and an air compressor (14), an air storage tank (15), a turbine (16) and a generator (17). Air is compressed and stored in the air storage tank when the air compressor starts up. The air storage tank is provided with a switch valve, and under the control of the switch valve the air stored in the air storage tank is fed to the turbine. By means of providing an air compressor, an air storage tank, a turbine and a generator, and using air energy to generate power and using the battery to supply power in parallel, the continuous mileage of the electric vehicle is increased. In addition, the service life of the battery is prolonged, because the battery is used in a low depth of charge/low depth of discharge manner.

The present invention relates to a work machine, in particular in the form of a dump truck or truck, comprising a traction drive unit and/or main work unit which can be driven by a drive apparatus comprising at least one electric motor. The invention further relates to a method for operating such a work machine, in accordance with the invention, the drive apparatus comprises at least one hydraulic motor supporting the electric motor, the hydraulic motor being switched in for starting the drive apparatus and being decoupled on an exceeding of a predefined speed.

A selectable one-way clutch comprises inside clutch elements and outside clutch elements. The inside clutch elements include: an inside pocket plate where inside pawl members are held; an inside notch plate where inside recesses to engage with the inside pawl members are formed; and an inside selector plate disposed between the inside pocket plate and the inside notch plate. The outside clutch elements include: an outside pocket plate where outside pawl members are formed; an outside notch plate where outside recesses to engage with the outside pawl members are formed; and an outside selector plate disposed between the outside pocket plate and the outside notch plate. The inside clutch elements and the outside clutch elements are disposed concentrically using one axial line as a center.

A controller for controlling a multi-phase motor is described. The controller may be configured to drive a first virtual multi-phase motor in an active mode and drive a second virtual multi-phase motor in a passive mode. In the active mode, at least a portion of a reference torque is distributed to the first virtual multi-phase motor. In the passive mode, zero torque is distributed to the second virtual multi-phase motor.

A clutch includes a first race, a second race, a pawl, a post, and a shoe. The second race defines a cam surface. The pawl is supported in the first race to pivot between an engaged position and a disengaged position such that contact between the cam surface and the pawl in the engaged position prevents relative rotation between the first and second races in at least one direction. The post is supported in the first race to slide between a first and a second position such that in the first position the post forces the pawl into the disengaged position. The shoe is configured to pivot with respect to the first race in response to a magnetic field to slide the post into the second position.

A machine is adapted for operation powered by any one of a plurality of interchangeable power sources. The machine may include an undercarriage configured for supporting ground engagement members that propel the machine and an upper structure rotatably supported on the undercarriage. The upper structure may include a swing frame, with the swing frame supporting an operator cab, any one of the plurality of interchangeable power sources, hydraulic components, electrical components, and a counterweight disposed at a first end of the swing frame. The counterweight may include a hollowed out portion facing toward the swing frame. The hollowed out portion of the counterweight may be centrally aligned with a center core portion of the swing frame configured for supporting any one of the plurality of interchangeable power sources, with the one power source being partially accommodated within the hollowed out portion of the counterweight.
