Vehicle battery pack comprising a support structure comprising, in turn, at least two elongated perimeter members facing one another and defining, between them, a box portion; several bulkheads arranged so to divide the box portion delimiting at least two housings, wherein the bulkheads are arranged transversely to the two perimeter elements facing one another; a plurality of planar, electrically connected electrochemical cells parallel both to one another and to the bulkheads and divided into at least two modules, wherein said at least two modules each comprise at least two insertion plates arranged at the ends of each module, parallel to the bulkheads, and configured to facilitate the insertion of each module under compression into the respective housing, so that the compression remains even after the insertion.

A steering device, including: a steering knuckle rotatably holding a wheel; an electric motor and a speed reducer configured to decelerate rotation of the electric motor, the electric motor and the speed reducer being fixed to a suspension arm; and a joint through which the steering knuckle is supported by the suspension arm in a state in which a kingpin axis is allowed to incline with respect to the suspension arm, the joint coupling the steering knuckle and an output shaft of the speed reducer such that the steering knuckle pivots about the kingpin axis by an operation of the electric motor.

A vehicle has a hybrid drive including an internal combustion engine and at least one electric motor. The hybrid drive has a charging device for generating an air flow. A charge air path guides the air flow from the charging device to the internal combustion engine. A charge air cooler is arranged in the charge air path between the charging device and the internal combustion engine. The hybrid drive has an electric battery for supplying electric power to the at least one electric motor. The effort involved in cooling the battery is reduced if the battery is incorporated into the charge air path between the charge air cooler and the internal combustion engine in such a way that the air flow can flow through and/or around it.

A vehicle body front structure (10) includes: a shutter mechanism (19), an under cover (20), and a cooling duct (21). The shutter mechanism includes an upper shutter (54) and a lower shutter (55). The under cover covers a power device, a cooling device, and a peripheral component from below. Air is sent from the lower shutter to the cooling duct, and the cooling duct includes: an intake port portion (75), a first discharge port portion (91), and a second discharge port portion (98). Air is sent from the lower shutter to the intake port portion. The first discharge port portion and the second discharge port portion are positioned at the back of a vehicle body of the power device, and send air toward the peripheral component.

A device for regulating an air stream for an air inlet of a motor vehicle may include a duct defining a flow channel in which an air stream flows. A cooling unit is arranged in the duct and includes at least one heat exchanger and a motor-fan unit. Additionally, the duct includes at least one sound absorption means arranged so that it at least partially limits the propagation of noise annoyance to the outside of the duct. A motor vehicle may include the regulation device.

Provided is a construction machine capable of collecting foreign matter into a dust collection pocket and preventing the foreign matter from being scattered. The construction machine includes a cooler, an air passage forming member including a curved section, a dust-proof filter, a cooling fan generating a normal wind for cooling and a reverse wind opposite thereto, a dust collection pocket, and a turning member. The dust collection pocket has an opening and collects foreign matter at a position downstream of the inner wall surface of the outer corner of the curved section. The turning member is turned about a turning axis by the normal wind and the reverse wind, thereby being moved between a close position to close the opening and an open position to open the opening.

A battery case of a battery storage device is disposed on a vehicle floor, thereby securing an interior space. A battery module of the battery storage device can be cooled by using an interior air, thereby simplifying a cooling structure and saving a manufacturing cost. In addition, the battery storage device for an electric vehicle blocks noise generated by a cooling device and an electrical component from flowing into the interior, thereby preventing the occurrence of a passenger's discomfort feeling caused by the noise.
