A work vehicle according to the present invention includes an engine installed in a traveling machine body supported by traveling units, and a transmission case incorporating a hydraulic continuously variable transmission. The transmission case incorporates a forward/backward traveling switching mechanism. The work vehicle includes forward traveling valves for forward traveling hydraulic clutches, a backward traveling valve for a backward traveling hydraulic clutch, and a master valve configured to control hydraulic oil supplying to the forward traveling valves and the backward traveling valve. A part of a hydraulic circuit is formed on a front lid member of the transmission case. The forward traveling valves, the backward traveling valve, and the master valve are attached on a front surface side of the front lid member.

A fuel cell system includes a stack case storing a fuel cell stack, and an auxiliary device case containing a fuel gas system device and an oxygen-containing gas system device. The auxiliary device case covers the fuel gas system device in a manner to protect the fuel gas system device against the external load, and includes a first case member provided with a mount fixed to a vehicle body frame, and a second case member made of material having specific gravity smaller than that of the first case member, and covers at least the oxygen-containing gas system device.

A battery module can include multiple cell tubes and a conductive plate. The multiple cell tubes can accommodate multiple battery cells within the multiple cell tubes so that individual of the multiple battery cells are positioned within individual of the multiple cell tubes. The conductive plate can include a printed circuit board. The printed circuit board can include a first conductive layer and an isolating layer. The isolating layer can include a blind hole through which a wire bonding extends. The wire bonding can be electrically connected to the first conductive layer.

Axle assembly includes first and second axle housings extending toward opposing sides of a vehicle frame with the axle housings aligned to define an axle axis, first and second wheel ends, first and second drive shafts disposed within the first and second axle housings, a gearbox having a first surface facing one side of the vehicle frame and a second surface facing the other side of the vehicle frame with the gearbox cantilevered outwardly relative to the aligned axle housings to define a gearbox axis parallel to a longitudinal axis of the vehicle frame and transverse to the axle axis, and an electric motor coupled to the second surface of the gearbox and extending toward the first side of the vehicle frame to define a motor axis that is parallel to and offset from the axle axis, transverse to the gearbox axis, and transverse to the longitudinal axis.

A vehicle includes: a center tunnel which is formed on a floor panel so as to extend in a front-rear direction; a high-voltage battery which is disposed on the center tunnel; and a frame member which holds the high-voltage battery, wherein leg portions are provided on a bottom portion of the frame member so as to extend obliquely downwards, and wherein the frame member is fastened to inclined surfaces of the center tunnel via the leg portions.

A motor gearbox assembly is provided for a vehicle having two wheels on opposite sides of the vehicle. The assembly includes two independent drive systems that each include an electric motor and an associated gear train, each drive system being configured to independently drive one of the wheels. The assembly further includes a common housing that receives the motors and the gear trains such that the gear trains are at least partially positioned between the motors. Furthermore, at least portions of the drive systems have generally inverse orientations in a longitudinal direction of the vehicle when the motor gearbox assembly is mounted on the vehicle.

A vehicle includes a floor panel, a battery module, a heater duct, and an exhaust duct. The battery module is disposed on the floor panel under a seat. The heater duct is disposed on the floor panel to discharge air output from an air conditioner through the heater duct. The exhaust duct is provided on the floor panel to discharge air output from the battery module through the exhaust duct. The exhaust duct intersects the heater duct viewed in a height direction of the vehicle.

A cover for a housing of an electric machine is provided. The cover may include an inner sidewall and an outer sidewall. The outer sidewall may be spaced apart from the inner sidewall to define a coolant channel therebetween. The inner sidewall and outer sidewall may be defined by an interior surface of the cover such that the coolant channel receives end windings of a stator of the electric machine when the cover is secured to the housing. The interior surface of the cover may define features between the sidewalls to promote turbulence of coolant flowing through the coolant channel. The interior surface of the cover may define a meandering trough between the sidewalls to form a predetermined coolant path relative to a location of the end windings when the cover is secured to the housing.

An electric power train for an automotive vehicle includes an electric motor, a power electronics system, a first casing containing the power electronics system, a second distinct casing that contains the motor, and a third distinct casing. The first casing includes a bottom and an opening for access to the power electronics system. The second casing bears on an exterior wall of the first casing bottom. The opening is opposite the second casing. The third casing is assembled on the first casing and contains an electric filtering system. The first casing includes a platform, which juts out relative to at least one portion of the first casing and on a face of which platform an assembly contour for assembling the third casing on the first casing is defined. The assembly contour is substantially parallel to an axial direction of the motor. The platform overhangs the second casing.

A vehicle mount structure for includes a stack case and a boss. The stack case accommodates a fuel cell stack. The stack case includes a bottom panel to be provided on a bracket member of a vehicle. The bottom panel includes a lower plate and an intermediate member. The lower plate is opposite to and below an upper plate in a height direction of the vehicle. The lower plate has an opening to surround a bearing surface of the bracket member. The intermediate member is disposed between the upper plate and the lower plate. The intermediate member has a thickness thicker than a thickness of the upper plate and a thickness of the lower plate. The boss is disposed on the intermediate member and includes a rib. The boss with the rib protrudes toward the bracket member to pass through the opening.
