Abstract:
An off-road vehicle is disclosed having a frame (32), at least four wheels (36, 38) suspended from the frame (32), a left seat (40B), a right seat (40A), an engine (48) mounted to a middle portion (62) of the frame (32), and a console (70) mounted on the middle portion of the frame (62) laterally between the left seat (40B) and the right seat (40B). The console (70) covers the upper portion of the engine (48) and defines a central cooling tunnel (88) extending forwardly and rearwardly of the engine (48) which tunnels air flow around the engine (48) for cooling the later. The off -road vehicle also features a passageway in front of the central cooling tunnel, and a fan aligned with the passageway to increase air flow through the central cooling tunnel (70) when required.

Abstract:
The invention concerns the problem of heating the passenger compartment by means of electrical resistance heating which loads the drive battery in the case of all-electric cars, and the problem of the internal combustion engine giving off more heat than is required for heating purposes in the case of hybrid vehicles. In order to overcome these problems, the invention proposes a car having a power-heat cogeneration system, in particular for private local travel. The coupling system comprises a series hybrid drive (Fig. 1) in which the internal combustion engine (32) is coupled only to a generator (30) and forms therewith a current unit which can provide only a fraction of the electrical power absorbed by at least one electric drive motor (10/12), which is constantly connected to an electric drive battery (22) which can be charged by means of the current unit. The coupling system further comprises an arrangement for heating the passenger compartment (66) by transfer of heat from the current unit to a heat transfer medium fed to the passenger compartment (Fig. 2).
Abstract:
In the operation of construction vehicles, the reduction of the noise associated with their operation has become a primary concern. A major source of the noise created by the operation of a vehicle resides with the engine and associated components utilized to power the vehicle. While these components have been encased in enclosures comprised of sound suppression material and restricted openings through which noise may escape, a severe problem has been created in obtaining proper airflow into the enclosure for adequate cooling of the surface temperatures of the components as well as the cooling systems for the fluids that circulate internally through the drive train components. Additionally, the temperature rise experienced within a tightly sealed engine enclosure can exceed the allowable maximum temperatures of components such as microprocessors. The ventilation apparatus (51) of the present invention provides an airflow control system that is designed to minimize noise while providing adequate airflow both during engine operation and after engine shutdown. The enclosure (24) that is devided into first and second compartments (26, 28). The first compartment (26) houses the drive train components (14) and the second compartment (28) houses the fluid cooling apparatus (30). The first compartment (26) is provided with at least one air communicating means (52) to transfer ambient air from outside the enclosure through a circuitous air passageway (54) lined with sound absorptive material (60, 62). The air passageway (54) is formed in at least one of the walls that forms the first compartment (26) so that it may be critically positioned with respect to the more heat sensitive components (14) housed within the enclosure (24) yet maximizing the efficient use of available space. A plurality of blowers (78) may be included in the air passageway (54) to selectively direct the flow of air toward selected portions of the first compartment (26).
Abstract:
A hybrid electric vehicle configuration of the dual configuration floor assembly includes a single-piece integrally-molded thermoplastic coupling seal plate having an interior and exterior side and including: (1) a coolant delivery passage extending through coupling seal plate and having an interior and an exterior quick-connect coolant delivery coupling at respective ends of the coolant delivery passage; (2) a coolant return passage extending through the coupling seal plate with an interior and an exterior quick-connect coolant return coupling at respective ends of the coolant return passage; (3) an electrical harness opening through the coupling seal plate; and (4) floor-plate coupling elements. A non-hybrid electric vehicle configuration of the dual configuration floor assembly includes an operating unit and an operating unit gasket positioned around an interior side of the floor opening between the operating unit and the sheet metal floor component.
