A vehicle battery pack support device applicable to various classes of vehicles and allowing weight reduction and cost reduction. The vehicle battery pack support device suspends a battery pack at a side rail constituting a ladder frame of a vehicle and includes a frame-side bracket secured by bolts to an outer side face of the side rail at a plurality of bolt fastening parts thereof arrayed in a grid arrangement. An elastic coupling part elastically couples the battery pack and the frame-side bracket. A spacer is interposed between the outer side face of the side rail and the frame-side bracket. The spacer includes a plurality of columnar members corresponding to the plurality of bolt fastening parts and a connecting part that connects the plurality of columnar members.

The present disclosure relates to a battery system for a hybrid or an electric vehicle. Another aspect of the present disclosure provides a battery assembly designed for easy and quick exchange of battery assemblies enabling a vehicle to resume driving much more quickly than traditional charging permits.

In a fuel cell vehicle, an occupant room is disposed at a front part of a vehicle body frame, and a rear side of the occupant room of the vehicle body frame is a load mount part. A hydrogen handling device is supported at least by the load mount part. The fuel cell vehicle includes a cover room that surrounds at least an upper part and a side part of the hydrogen handling device that is supported by the load mount part. A load room is disposed on the load mount part of the vehicle body frame. A discharge duct that discharges a hydrogen gas in the cover room upward from between the load room and the occupant room is connected to the cover room.

A transmission includes a transmission main housing, an intermediate plate secured to the transmission main housing; and a rear housing attached to the intermediate plate and/or attached with fasteners through the intermediate plate to the main housing. An input shaft is connected to an extension shaft including a plurality of splitter gears selectively couple-able to the extension shaft. A main shaft is rotatably supported by the range shaft and range shaft bearing and includes a plurality of main box gears selectively couple-able to the main shaft. A range shaft is drivingly connected to the main shaft and provides input to a planetary gear assembly. The extension shaft is supported at a first end by a bearing assembly within a partition wall of the main transmission housing and a second end is supported by a bearing assembly disposed within the bore in the range shaft.

A multistage airbag impact absorption apparatus of a truck is made of urethane and characterized by an airbag that has a plane shape on one side and an elliptical shape on the other side and has two air perforations attached with a perforated part and air inlet and outlet part, a core part formed with many core perforations attached to the airbag, a base plate formed with plate perforations and attached to the core part that helps the perforated part project out upon collision with the air inlet and outlet part, an air inlet and outlet part attached to air perforations of the airbag, core perforations of the core part and plate perforations of the base plate, a second impact absorption part attached to both sides of the base plate, and a second base plate that is attached to the truck body and supports the second impact absorption part.

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 tractor-trailer is disclosed, with associated apparatuses. A tractor may include a tractor air duct disposed underneath a cab. The tractor air duct may extend between a front opening at a front of the tractor and a rear opening at a rear of the tractor. A trailer may include a duct system that receives airflow from the rear opening of the tractor air duct and directs the airflow to a location behind a cargo compartment. 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.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

A vehicle body management system for managing a vehicle body having a power train formed by a plurality of parts including a prime mover, the vehicle body management system including: a processing device that computes an efficiency value of a monitoring target, the monitoring target being the power train or a part or a subsystem of the power train, on the basis of information about the vehicle body, the information being sensed by a sensor provided to the vehicle body; and an output terminal that outputs the efficiency value of the monitoring target, the efficiency value being computed by the processing device, the processing device computing a load parameter of the power train, determining whether the load parameter is larger than a load determination value set in advance, computing the efficiency value of the monitoring target on the basis of input energy and output energy of the monitoring target on condition that the load parameter be larger than the load determination value, and recording the computed efficiency value of the monitoring target.
