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.
Claims10
An engine mount assembly for mounting an engine to a vehicle frame, said engine mount assembly comprising:
- an elastomeric material snubber element, said snubber element comprising a generally cylinder configuration with axial end faces and a bolt passage defined therethrough coaxial with a longitudinal axis of said snubber element;
- a tubular sleeve having an inner diameter sized for sliding receipt of said snubber element therein;
- said tubular sleeve comprises 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 a vehicle frame flange;
- wherein said tubular sleeve comprises an upper longitudinal cross-sectional portion that tapers from said bottom longitudinal cross-sectional portion towards said axial end faces of said snubber element;
- and
- wherein said snubber element has an axial length so as to fit between mounting arms of an engine frame, 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.
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;
- 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 cylinder configuration with axial end faces and a bolt passage defined therethrough coaxial with a longitudinal axis of said snubber element;
- a tubular sleeve having an inner diameter 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 said tubular sleeve to said mounting flange on said vehicle frame.
