An air distributor may be disposed behind the cargo compartment. An air distributor may include a fairing with openings, so that airflow from the duct system enters a space between the cargo compartment and the fairing, and exits the openings behind the trailer.

To provide a power regeneration system for a working vehicle that can effectively use a regenerative electric energy.

A first electric circuit for supplying an electric power generated by the first generator to a traveling motor, a voltage detector for detecting an actual voltage of the first electric circuit, a second electric circuit for supplying an electric power generated by a second generator to an auxiliary device, a step-down device connected to the first electric circuit and the second electric circuit, and a controller are provided. The controller estimates the voltage of the first electric circuit after a predetermined time has elapsed from the present time, based on information on a traveling state of a work vehicle and the actual voltage detected by the voltage detector, and outputs a drive command to the step-down device when the estimated voltage is equal to or more than a threshold.

A traveling device (11) is provided with an electric motor (16) provided in a vehicle body (2) of a dump truck (1), an output shaft (17) an axial base end of which is connected to the electric motor (16) and which outputs rotation of the electric motor (16), a bottomed hole spline (53) formed in an axial front end of the output shaft (17), and an input shaft (42) which has a shaft spline (54) spline-coupled to the hole spline (53), and inputs the rotation of the output shaft (17) to a reduction gear mechanism (27). The output shaft (17) is provided with an oil reservoir space (55) formed in the innermost part of the hole spline (53), an annular oil groove (56) and an oil path (57) providing communication between the oil reservoir space (55) and the annual oil groove (56). Lubricant oil (100) supplied to the annular oil groove (56) is supplied via the oil path (57) to the oil reservoir space (55), and is supplied to a spline joint between the hole spline (53) and the shaft spline (54) with rotation of the output shaft (17).

A transmission arrangement for a vehicle includes a first, a second, a third, and a fourth planetary gear set including a sun gear, a planet carrier and a ring gear, respectively, wherein the transmission arrangement further includes a transmission housing, an input shaft and an output shaft, wherein two of the sun gear, the planet carrier and the ring gear of the fourth planetary gear set are each operatively connected to a respective one of the input shaft, the sun gear, the planet carrier and the ring gear of the third planetary gear set.

Disclosed is a roof fairing for a vehicle, such as a truck hauling a trailer. The roof fairing includes a body defining a flow directing exterior surface. The body including at least one flow directing channel that is sunk into the body toward an inner space defined by an interior surface of the body. The flow directing channel comprises a venturi construction terminating at the trailing edge. The venturi construction is configured to direct flow toward an exterior surface of the trailer when coupled to the truck.

A vehicle is proposed to control regeneration and reuse of captured energy in a through-the-road hybrid configuration. The vehicle comprises a vehicle frame, an energy store, and a controller. The vehicle frame is configured for over-the-roadway travel under a power of plural drive axles. At least one of the plural drive axles is coupled via a primary drivetrain to a fuel-fed engine to drive at least a pair of wheels. At least one other of the plural drive axles is an electrically-powered drive axle configured to supply supplemental torque to additional wheels. The energy store is configured to supply the electrically-powered drive axle with electrical power in a first mode of operation and receive energy recovered using the electrically-powered drive axle in a second mode of operation. The controller is coupled between the electrically-powered drive axle and one or more sensor inputs to transition between different modes of operation.

A connector for connecting a frame member to one or more other frame members of a space frame assembly is disclosed. The connector includes a body defining a surface and a projection extending outwardly from the surface along a main axis to define an axial end surface away from the surface. The axial end surface defines a curvature having continuity across an expanse of the axial end surface to facilitate formation of a full penetration weld joint between an end of the frame member and the axial end surface upon a contact of the end of the frame member with the axial end surface.

The invention relates to a system for installation of traction batteries for a vehicle having a chassis comprising at least one load-carrying frame member. A front bracket member and a rear bracket member are adapted to be secured to and project from the frame member of the vehicle for receiving a traction battery between the front bracket member and the rear bracket member. The system also comprises a first and a second slider adapted to be connected to a front and a rear side, respectively, of a traction battery. The sliders are adapted to be mated with the bracket members subsequently to the sliders having been connected to the traction battery, thereby enabling the traction battery by means of the connected sliders to be received by the bracket members and be moved towards the frame member of the vehicle.
