A first connector on a case front wall of a battery pack is connected to a first electric motor with a first power line interposed therebetween. A second connector on a case rear wall of the battery pack is connected to a second electric motor with a second power line interposed therebetween. A fuel tank is arranged behind the battery pack. A muffler is disposed on an exhaust pipe extending from an engine toward the rear along a side surface in a vehicle width direction of the battery pack and is inclined so as to be near the fuel tank behind the battery pack. The second power line is at least partially arranged in a space surrounded by the second connector, the fuel tank, and the muffler as seen in a vertical direction.

Assembly (1) comprising at least one vehicle wheel (2), adapted to rotate about a vehicle wheel axis (X2) and adapted to perform a rolling movement on an advancement surface for the vehicle; at least one further rotating member (4), which can be operatively connected to said vehicle wheel (2); at least one transmission (6) adapted to transmit kinetic power between said vehicle wheel (2) and said at least one further rotating member (4); wherein said transmission (6) achieves a transmission ratio other than +1; at least one braking device (18) acting on said at least one further rotating member (4) in order to brake said vehicle wheel (2) by means of a braking action acting on said at least one further rotating member (4) which is transmitted to the vehicle wheel (2) by means of said transmission (6)

A fuel cell vehicle includes a fuel cell, an oxygen-containing gas supply apparatus, and an ECU. A pump of the oxygen-containing gas supply apparatus is a shaft floating type air pump having a rotatable element. The rotatable element floats from a wall around the rotatable element, as a result of rotation of the rotatable element. The ECU includes a travel permission determination instruction unit. The travel permission determination instruction unit determines whether or not a predetermined condition indicative of a floating state of the rotatable element is satisfied, and if the predetermined condition is satisfied, permits traveling of the fuel cell vehicle, and if the predetermined condition is not satisfied, restricts traveling of the fuel cell vehicle.

A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is ‘free floating’.

A track assembly (15) for a track-driven vehicle, whereby the track-carrying beam (15) is arranged to hold a front and a rear wheel (16), one of which is driving, a plurality of carrying wheels about which wheels a continuous track travels, the track-carrying beam (15) is elongated and terminated by a first and a second gable end. The track-carrying beam (15) comprises an integrated compartment (37) and an opening (36) in one (35) of said gables, whereby the compartment (37) communicates with the surroundings via said opening (36), and whereby the opening (36) is arranged to allow for insertion of a transmission device for driving of said driving wheel (16) via the opening (36) in the compartment (37).

A hybrid straddle vehicle comprises a hybrid traveling driving power unit including an engine and a traveling motor, the hybrid traveling driving power unit being configured to generate driving power for allowing the hybrid straddle vehicle to travel; a fuel tank which stores therein fuel to be supplied to the engine; and a battery unit which stores therein electric power to be supplied to the traveling motor. An outer end of the fuel tank in a vehicle width direction is located outward of the battery unit in the vehicle width direction.

A method for operating a motor vehicle, which is equipped with a plurality of wheels and with a plurality of electric machines. Each electric machine can be coupled to at least one wheel and be operated in a plurality of operating modes. The respective electric machines perform rotations in a first engine operating mode in a first direction of rotations. Electric energy is converted to mechanical energy. The at least one wheel is rotated in a forward direction, whereby the vehicle is driven with the at least one wheel. The respective electric machines perform rotations in a second generator operating mode in a second direction of rotations, which is opposite to the first direction of rotations, whereby electric energy is converted to mechanical energy.
