A method is provided for use in a vehicle. The vehicle includes a transmission, a turbocharger, a transmission control module (TCM), an engine, and an engine control module (ECM). The engine includes a crankshaft that rotates at an engine speed and the turbocharger includes a turbine that rotates at a turbine speed. The method includes requesting a downshift of the transmission from an off-going gear ratio to an on-coming gear ratio. The turbine is rotating at an off-going turbine speed at the off-going gear ratio and the turbine is configured to rotate at an on-coming turbine speed at the on-coming gear ratio, greater than the off-going gear speed. A determination is made that the requested downshift is a powerdown low-throttle shift. An engine speed request value is then transmitted from the TCM to the ECM. The transmitted engine speed request value is at least equal to the on-coming gear speed.

A gear arrangement, in particular for a rotary connection of a wind turbine, comprising a first gear, a second gear in engagement with the first gear, wherein in the engaged position a gap space is provided between a first tooth and a second tooth of the first gear and a tooth of the second gear, and a sealing element which seals off the gap space to prevent lubricant escape.

Disclosed is an air cleaner comprising: a housing (H); an air-purifying filter (20); a blowing unit (30); and a channel switching member (200) for switching a discharge channel such that air supplied from the blowing unit (30) flows to at least one of a first discharge port (A51) to discharge air in a first direction and the second discharge port (A52) to discharge air in a second direction. The channel switching member (200) comprises: an elevating member (210) having a first communication unit (216) that is open such that air flows to a first discharge port-side channel (A3), and having a blocking unit (215) for blocking a flow thereof to a second discharge port-side channel (A4); and an opening/closing member (220). The first discharge port-side channel (A3) and the second discharge port-side channel (A4) are opened/closed by ascending/descending of the elevating member (210) and moving of the opening/closing member (220).

A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length and a width, in a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a motor for providing a drive energy to the first wheel, an axle rotated by the motor, a drive gear connected with the axle such that the drive gear rotates with a rotation of the axle, and a plurality of teeth disposed about the first wheel and mechanically engaged with the drive gear at a location closer to the perimeter of the first wheel than to the geometric center of the first wheel.

Integration of drive elements with an unsprung structure is disclosed. In one aspect of the disclosure, a motor includes a stator configured to mount to an unsprung structure of a wheeled vehicle through at least a damper or a spring. The motor further includes a rotor configured to drive a wheel of the vehicle.

A gearwheel arrangement for a transmission of a vehicle, such as an electric vehicle, including: a shaft extending along a longitudinal axis of rotation, including an internal axial duct for guiding lubricant, a gearwheel including a base portion centered on the shaft and a plurality of gear teeth provided around a periphery of the gearwheel, the gearwheel preferably being configured for common rotation with the shaft. The gearwheel arrangement further includes an internal radial duct for guiding lubricant from the internal axial duct to the gear teeth. The internal radial duct may extend at least in part behind a gearwheel cover.

Provided are a motor device and a method for manufacturing the same that can accurately and consistently provide a support shaft to a case and enhance the strength for fixing the support shaft to the case. A small-diameter part having a smaller diameter than a large-diameter part is formed through drawing. The large-diameter part and a step part are embedded in a gear case. The small-diameter part is exposed outside the gear case. The dimensional accuracy (dimensional tolerance ±α) of the external diameter of the small-diameter part is enhanced. The small-diameter part can be set, without rattling, in a lower mold for molding the gear case. Consequently, the support shaft can be accurately and consistently provided to the gear case. Because the large-diameter part and the step part are embedded in the gear case, the resistance of the support shaft against pulling from the gear case can be enhanced.
