An engine or radiator mounting sub-system comprised generally of an engine or radiator frame cross piece that is assembled to the engine or radiator off of the assembly line of a mobile vehicle. The off-line assembly allows the engine mounts to be preloaded prior to assembly. The engine or radiator and frame cross piece module may be lowered into the chassis on an assembly line for final fastener engagement that comes through the side or top of the frame rails. In one embodiment, the frame cross piece has an end bracket on each end that allows the lowering in of the engine or radiator into exact forward and aft placement on the respective frame rails. There may be frame rail brackets that have 'L' shaped ends. Where these 'L' brackets are used, the length of the frame cross piece including the &lsquo;L&rsquo; brackets out to the outer vertical face will closely approximate the width between the rails. During vehicle manufacture, the frame crosspiece would be installed to the engine or radiator. The engine or radiator and frame cross piece combination would be moved to the chassis on an assembly line. The horizontal portion of the &lsquo;L&rsquo; brackets will rest on the upper surfaces of the frame rail. The final engagement or bolt up would occur to and through the top and or side of the frame rails.

L-bracket modular front engine mounting

A mount for securing a component, such as an engine, to a vehicle frame. Preferably, the mount includes a bottom and top isolator and a cross member that can be assembled and secured to the engine at an assembly station away from the primary assembly line. The cross member includes frame mounting surfaces that are vertically oriented at each side of the cross member, and the frame includes corresponding engine mounting surfaces. A receiver with a downward facing surface is also provided that is attached to the cross member. A stop support that is attached to the vehicle frame supports the weight of the engine with an upward facing support surface that abuts the receiver support surface.

Component mount for a vehicle frame

An engine mounting assembly includes a pair of rear engine mounting bracket assemblies having offset mounting surfaces, an engine flywheel housing having complementary mounting surfaces, and a front mounting bracket which together provide a three-point mounting structure resulting in a significantly lowered mounting of the engine on a forward control bus chassis. The front mounting bracket includes a single point, vibration-isolated, engine mount to a lowered frame crossmember to provide vibration isolation in any direction while the rear brackets provide vertical and fore-and-aft vibration isolation. The front mounting bracket further includes a lower mount for supporting a vehicle radiator while upper stabilizing rods connect the upper portion of the radiator to the upper portion of the engine to stabilize the desired vertical position of the radiator perpendicular to the engine fan axis.
