A motor vehicle, in particular with an electric drive, having a battery system and an underride protection plate. The underride protection plate is arranged in the motor vehicle at least in sections under the battery system. The battery system includes a battery module, which includes a first wall in a first region of the battery system and a second wall in a second region of the battery system. The underride protection plate is formed in such a way that the underride protection plate directly or indirectly abuts the battery system in the first region and in the second region at least in sections, and, between the first region and the second region, forms a first section of a gas channel between the battery system and the underride protection plate.

A vehicle, in particular having an electric drive, wherein the vehicle includes a battery system and an underride protection plate. The underride protection plate is arranged in the vehicle at least partially under the battery system. A gas channel is configured between the battery system and the underride protection plate. The underride protection plate includes at least one bulkhead having a first edge, at which the bulkhead is attached to the underride protection plate. The bulkhead extends from the first edge in the direction of the battery system to a second edge. The bulkhead at least partially forms a part of the gas channel. The bulkhead is configured so as to be foldable in the event of an upwards mechanical load on the underride protection plate at the first edge or between the first edge and the second edge.

Interchangeable track systems for interchangeable deployment with vehicle wheels on a forestry harvester vehicle having a front axle and a rear axle may include a pair of front roller frame mount arms and a pair of rear roller frame mount arms configured for mounting on the front axle and the rear axle, respectively. A pair of front track assemblies and a pair of rear track assemblies may be configured for removable mounting on the pair of front roller frame mount arms and the pair of rear roller frame mount arms, respectively. Each of the pair of front track assemblies and the pair of rear track assemblies may include an elongated roller frame configured for pivotal attachment to the corresponding one of the pair of front roller frame mount arms and pair of rear roller frame mount arms. A front idler roller and a rear idler roller may be carried by the roller frame. A track may be trained on the front idler roller and the rear idler roller. A sprocket may be configured for driving engagement by a corresponding one of the front axle and the rear axle, with the sprocket drivingly engaging the track.

A vehicle includes an undercover that covers at least from a lower part of a grille to a rear end of a front wheel of a floor undersurface of a vehicle body. The undercover includes a first slope and an opening. The first slope slopes vertically downward from a front side toward a rear side of the vehicle. The opening is disposed on a rear side of the front wheel. A space for guiding air toward the rear side of the front wheel is provided between the undercover and a drive power mechanism that is mounted on a front part of the vehicle body.

A multipurpose vehicle, including: a drain outlet for waste fluid; a skid plate covering a body of the multipurpose vehicle from below and having an opening in an area facing the drain outlet; and a spread prevention section surrounding the opening and configured to prevent spread of liquid near the opening.

In an undercover structure according to the present invention, a first cover part that is a lowermost part of an undercover has a first rear end positioned ahead of a front wheel axle. This generates a strong negative pressure in a region ahead of the front wheel axle. Accordingly, a flow rate of air flowing to a wheelhouse decreases (a flow rate of airflow between a road and a vehicle generated along a bottom surface of the first cover part of the undercover increases). This causes an attraction force that attracts the vehicle to a road surface to act on a vehicle body of the vehicle, thereby making traveling stability more excellent.

The present disclosure is directed to a slider bar to protect a battery pack of a vehicle. The battery pack is housed on an underbody in between the vehicle's front and rear axles. The battery pack protrudes towards the ground. The battery pack can optionally be covered by a shield that has a slot through which the slider bar extends outwards towards the ground. The slider bar is coupled to the underbody near the battery pack. The slider bar is positioned lower than the battery pack such that in an event of the vehicle bottoming out, the impact will be absorbed by the slider bar instead of the battery pack. Thereby, the slider bar protects the battery pack from scraping/scratching the ground.

Rock rail assemblies are provided for motor vehicles. An exemplary rock rail assembly may include a beam structure, an energy absorbing structure, and an outer skin. The energy absorbing structure may reinforce the beam structure and may be configured to distribute point loads when an obstacle impinges upon the rock rail assembly. The beam structure may be made of a metallic material, the energy absorbing structure may be made of a foamed polymer-based material, and the outer skin may be made of a polymer-based material. The rock rail assemblies may be constructed in a manufacturing method that involves roll forming and extrusion processes.

Techniques are directed to a modular vehicle belly armor kit, as well as systems and methods which utilize such a kit. The kit includes a bottom plate, a top plate, and a plurality of wall sections connecting with the bottom plate and the top plate to form an armor structure that protects a belly portion of the vehicle. After the modular vehicle belly armor kit is positioned underneath a vehicle, the bottom plate may be placed in contact with the vehicle. After the bottom plate is placed in contact with the vehicle, the bottom plate may be fastened to vehicle.

A vehicle including a frame, a cabin, and a blast mat. The cabin is coupled to the frame and includes a seat and a series of walls. The blast mat has a bottom surface engaging at least one of the walls. The blast mat includes a first portion configured to support a first portion of an occupant seated in the seat and a second portion configured to support a second portion of the occupant. The first portion of the occupant and the second portion of the occupant have different resistances to blast energy. The second portion of the blast mat has a greater thickness than the first portion of the blast mat.
