Abstract: A distribution gear mechanism with a torque transmission device having a clutch, a fluid sump configured to receive a lubricating fluid, wherein a lower cog is configured to engage in the fluid sump such that the lubricating fluid is conveyed from the fluid sump in the direction of an upper cog by way of a chain drive, a fluid reservoir configured to collect the lubricating fluid and which is fluidically connected to the fluid sump, an adjustment mechanism configured to open and close an outlet opening of the fluid reservoir to the fluid sump, and an actuating mechanism configured to simultaneously activate the adjustment mechanism and the clutch.

Abstract: A drive unit for a hybrid vehicle which has a front axle and a rear axle, having an internal combustion engine, which is arranged in the region of the front axle, for driving at least the rear axle, an electric machine for driving the front axle, and a front axle differential which has an input member for receiving a drive power output from the electric machine, and two output members for coupling to a respective wheel of the front axle. The electric machine and the front axle differential are arranged along the front axle on opposed sides of the internal combustion engine, the electric machine being coupled in drive terms to the input member of the front axle differential via a connecting shaft which is guided through an oil sump of the internal combustion engine.

Abstract: A method of calibrating a mirror orientation system of a heliostat includes mounting an artificial light source to a heliostat mirror, providing an array of light sensors on a solar thermal tower and positioning the heliostat mirror at a first orientation. A control module is provided a signal indicative of a mirror drive mechanism position at the first mirror orientation. The control module correlates the signal indicative of the mechanism position with an energy distribution across the sensor array as the artificial light source is energized when the mirror is at the first orientation. The drive mechanism moves the mirror to a second orientation and directs artificial light on the sensor array. The drive mechanism position signal is correlated with an energy distribution across the sensor array based on the second mirror orientation. The heliostat is calibrated based on the energy distributions and the drive mechanism position signals.

Abstract: A heliostat for reflecting sunlight toward a target includes a first structure supporting a mirror including inner and outer tubes being rotatable relative to one another. A first actuator includes an electric motor driving a reduction gearset to rotate one of the first tubes and rotate the mirror about a first axis. A second structure also includes inner and outer rotatable tubes. A second actuator includes a second electric motor driving a reduction gearset to rotate the mirror about a second axis.

Abstract: The invention relates to a wheel hub drive for a motor vehicle, having a motor, in particular an electric motor, which is connected to an input element of a transmission so as to exercise a driving effect, wherein the transmission has an output element, which is connected to a shaft section, by means of which a wheel of the motor vehicle can be driven. A sensor is furthermore provided for monitoring the rotational speed of the drive, comprising a sensor element arranged in a manner fixed against rotation and a rotatable sensor element. The rotatable sensor element is connected to the output element for conjoint rotation.
