A vehicle body lower structure includes a pair of left and right side sills, a battery pack and a bulkhead. The side sill is disposed below a side portion of a vehicle body and extends in a vehicle body forward/rearward direction. The battery pack accommodates a battery cell therein, and both end portions in a vehicle width direction are fixed to the left and right side sills while being disposed below a floor panel. The bulkhead is disposed inside of the side sills and reinforces a cross section of the side sills from inside. The bulkhead is provided at front and rear positions on the vehicle body and inside the side sills while having fixing points of the side sills to the battery pack sandwiched between the front and rear positions.

An off-road vehicle having a frame, a plurality of ground engaging members operably coupled to the frame, a seat supported by the frame and configured to support an operator, an engine supported by the frame, a body supported by the frame, and a liner coupled to the body, where the liner is configured to be positioned between the body and a heat source of the off-road vehicle, and an air gap extends between the liner and the body.

A vehicle body lower structure includes: a battery pack provided below a floor panel and in which a cell is received in an inside of a case; a side frame extending in a vehicle body forward/rearward direction at an outer side of the battery pack in a vehicle width direction and configured to support the battery pack; and a support bracket having a first extension section that is fixed to the cell and that is disposed at an inner side in the vehicle width direction, and a second extension section that is fixed to a longitudinal wall section of the case and that is disposed at an outer side in the vehicle width direction, wherein the second extension section extends in an upward/downward direction at an inner side of the side frame in the vehicle width direction.

Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

A motor-vehicle underbody liner, encompassing a planar porous open-cell carrier component; the carrier component being embodied for mounting onto a motor-vehicle underbody and for being carried along therewith; the carrier component including an installation side that faces toward the motor-vehicle underbody during operation as intended, and a liner side that faces away from the motor-vehicle underbody during operation as intended; the carrier component being adjusted, by suitable densification of its open-cell material, to a sound absorption behavior having a sound absorption maximum in a frequency range from 800 Hz to 1250 Hz; there being arranged on the installation side of the carrier component an additional absorber component having a sound absorption behavior whose sound absorption maximum is also located in a frequency range from 800 Hz to 1250 Hz.

A rocker molding includes a vertical wall portion provided under a rocker in a vehicle upper-lower direction, a bottom wall portion extending from a lower end portion of the vertical wall portion to an outer side in a vehicle width direction, and a side wall portion extending upwardly in the vehicle upper-lower direction from an outer end portion of the bottom wall portion in the vehicle width direction. A sound absorbing material is provided in a penetrating portion that is provided in a grange from a portion of the vertical wall portion to an inner portion of the bottom wall portion in the vehicle width direction.

A fastening body for fastening an underbody liner component to a motor vehicle underbody, the fastening body encompassing a bracing segment having a passthrough opening penetrable along a penetration axis by a fastening means when the fastening body is in the operationally ready state, and having a bracing region, embodied in the surrounding region of the passthrough opening, which is provided for abutment of a counterpart bracing region of the fastening means; a liner segment that is arranged at a distance from the bracing segment and comprises, at least on its outer side facing away from the bracing region, a preferably flat outer surface; and a connecting segment connecting the bracing segment and the liner segment.

To provide a method for the production of components, in particular wheel well liners of vehicles, in which the component is produced in a spread out or unfolded form and at a later time is moved into a curved or folded form, wherein in an area of a bending point, a material strength of the component decreases as compared to a material strength of the adjacent area, it is suggested that the minimum thickness of the material in the area of the bending point is molded to be 40% to 60%, preferably 45% to 55%, more preferably about 50% less than the material strength of the adjacent area.

A description is given of the use of a polymer dispersion for producing sound deadener compositions, the polymer dispersion comprising at least one polymer obtainable by emulsion polymerization of radically polymerizable monomers, and the polymer having a weight-average molecular weight of more than 100 000, preferably of more than 100 000 to 350 000. A description is also given of corresponding sound deadener compositions which comprise the polymer dispersion, and of a method for damping oscillations or vibrations of vehicle components.

A vehicle lower structure includes an internal combustion engine arranged in an engine compartment of a vehicle; a lower cover arranged below the internal combustion engine and formed so as to cover a lower portion of the engine compartment; and one or more baffle plates arranged between the internal combustion engine and the lower cover. The one or more baffle plates are located within a range of the width of the internal combustion engine in the engine compartment with respect to the front-rear direction of the vehicle. The one or more baffle plate protrude toward the lower cover from the side of the internal combustion engine or toward the internal combustion engine from the side of the lower cover with respect to the top-bottom direction of the vehicle. The one or more baffle plate are formed so as to extend to the left-right direction of the vehicle.
