Problems solved by technology

But traditional hoods cause many problems due to the thermal expansion of the various parts of the hood
Traditional hoods also have an impact on visibility ahead of the tractor cab
Traditional engine covers generally have a relatively rigid outer panel that is finished so that it is permanently damaged when impacted by an object, and it is directly exposed to the heat emitted by the engine

Embodiment Construction

[0014] as attached figure 1 And attached figure 2 An agricultural vehicle 10 is shown having an engine 12 positioned forward of an operator's cab 14 and a hood assembly 16 joined to the tractor by a hinge 15 . It is best to refer to the attached figure 2 The hood assembly 16 includes an inner hood support 18 having a top surface 20 connected to the left and right sides 22 , 24 and also connected to the front side 26 . In order to achieve higher rigidity, the hood support 18 is preferably made of a plastic material with a higher glass fiber content. Top surface 20 includes a suction inlet 19 that is aligned with the location of an intake filter (not shown) of engine 12 .

[0015] The hood assembly 16 also includes a finished outer panel assembly 30 consisting of a finished top panel 32 mounted on the top surface 20, a mounting assembly including the headlight assembly 36, grille 38 and trim panel 40. Finished front outer panel assembly 34 on front side 26 , a finished lef...

Abstract

A vehicle hood assembly includes a hood support having a top section joined to left and right side sections and to a front section. An outer panel assembly includes a finished top panel mounted on the top section, a finished front panel assembly mounted on the front section, a finished left side panel mounted on the left section, and a finished right side panel mounted on the right section. Each panel and its respective section form and enclose an air space therebetween. Thus, the inner support and the air space is interposed between the finished panels and the heat from the engine. As the hood is raised, the lower portions of the side panels engage a wear strip and are deflected laterally outwardly and away from each other. As the hood is lowered, the lower portions of the side panels move past the wear strip, and they move laterally inwardly and towards each other.

Description

field of invention [0001] The present invention relates to an engine cover assembly capable of covering the engine and other components of, for example, agricultural or construction vehicles. Background technique [0002] It is a known technology to equip a tractor with a hood that can seal the engine and other parts of the tractor. But conventional hoods present many problems due to thermal expansion of the various components of the hood. Traditional hoods also have an impact on visibility in front of the tractor cab. Conventional engine covers generally have relatively rigid outer panels that are finished so that they are permanently damaged when impacted by objects, and are directly exposed to the heat emitted by the engine. Contents of the invention [0003] It is an object of the present invention to provide a vehicle hood assembly capable of accommodating thermal expansion of its components. [0004] It is another o...
