Abstract

An engine mount assembly is provided for mounting an engine to a vehicle frame. The engine mount assembly includes an elastomeric material snubber element having a generally elongated configuration with axial end faces and a coaxial bolt passage defined therethrough. A tubular sleeve has an inner shape sized for sliding receipt of the snubber element therein. The tubular sleeve has a longitudinal cross-sectional profile such that a bottom longitudinal cross-sectional portion of the tubular sleeve extends axially beyond the end faces of the snubber element and defines an enlarged attachment footprint for the tubular sleeve to a vehicle frame flange.

First claim

What is claimed is:

1. An engine mounting system, comprising:
an engine frame, said engine frame further comprising spaced-apart mounting arms at a mount position;
a vehicle frame, said vehicle frame comprising a mounting flange proximate to said mount position; and
an engine mount assembly at said mount position, said engine mount assembly further comprising:
an elastomeric material snubber element, said snubber element comprising a generally elongated configuration with axial end faces and a bolt passage defined therethrough coaxial with a longitudinal axis of said snubber element; and
a tubular sleeve having an inner shape sized for sliding receipt of said snubber element therein,
said tubular sleeve comprising a longitudinal cross-sectional profile such that a bottom longitudinal cross-sectional portion of said tubular sleeve extends axially beyond said end faces of said snubber element and defines an enlarged attachment footprint for attaching said tubular sleeve to said mounting flange on said vehicle frame,

wherein said tubular sleeve comprises an upper longitudinal cross-sectional portion that tapers from said bottom longitudinal cross-sectional portion towards said end faces of said snubber element, and
wherein said snubber element has an axial length so as to fit between said mounting arms, said upper longitudinal cross-sectional portion having an axial length so as to also fit between said mounting arms, said lower longitudinal cross-sectional portion having an axial length that extends axially beyond said mounting arms.

2. The engine mounting system as in claim 1 , wherein said tubular sleeve comprises a generally trapezoidal longitudinal cross-sectional profile.

3. The engine mounting system as in claim 1 , wherein said mounting flange defines a seat for receipt of said tubular sleeve, said seat comprising an alignment member configured thereon, and said tubular sleeve comprising a window in a rear face thereof at a location so as to engage with said alignment feature.

4. The engine mounting system as in claim 1 , further comprising at least one attachment stud configured on said bottom longitudinal cross-sectional portion at a location so as to extend through a receiving hole in said vehicle frame flange.
