Abstract
Abstract A low spring rate ratio bushing suitable for use as an engine mount. The mount connects an engine to a vehicle chassis by means of an inner and outer member separated by a flexible member. A plurality of flexible legs connect the inner member and outer member in a manner which lessens the vibration transferred from the engine to the chassis.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
An engine mount adapted to be interposed between a first chassis portion and a second engine portion for driving said chassis, said mount comprising: an outer housing having means for attachment of one of the portions to be joined, said outer housing being formed from two separate and distinct pieces haveing a gap therebetween; an inner cylindrical member adapted to engage the second portion to be joined and an elastomeric member which has a portion encircling the inner cylindrical member and at least three arms having one end attached to the encircling portion and the other end in contact with the housing, whereby the vibration damping quanties are essentially radially constant.
Claim 2
Dependent Claim
111 words
An engine mount adapted to be interposed between a first chassis portion and a second engine portion for driving said chassis, said mount comprising: an outer housing having means for attachment of one of the portions to be joined, said outer housing being formed from two separate and distinct pieces haveing a gap therebetween; an inner cylindrical member adapted to engage the second portion to be joined and an elastomeric member which has a portion encircling the inner cylindrical member and at least three arms having one end attached to the encircling portion and the other end in contact with the housing, whereby the vibration damping quanties are essentially radially constant.
Claim 3
Dependent Claim
22 words
The engine mount of claim 1 wherein the ratio between the spring rates measured in any two radial directions is about 0.8-1.2.
Claim 4
Dependent Claim
135 words
An engine mount adapted to be interposed between a vehicle chassis and an engine adapted to drive said chassis, said mount comprising: an inner cylindrical member adapted to engage a portion of the vehicle chassis and be fastened thereto; an elastomeric member which has a portion encircling the inner cylindrical member and a plurality of arms extending radially outward from said cylindrical member, one end of each of said arms being attached to said encircling portion; and a housing including at least two members adapted to be attached to said engine, said housing surrounding the inner cylindrical member and elastomeric member, said housing being attached to the ends of said arms opposite said inner cylindrical member, the members of said housing having a gap therebetween in the longitudinal direction allowing compression of the outer housing.
Claim 5
Dependent Claim
135 words
An engine mount adapted to be interposed between a vehicle chassis and an engine adapted to drive said chassis, said mount comprising: an inner cylindrical member adapted to engage a portion of the vehicle chassis and be fastened thereto; an elastomeric member which has a portion encircling the inner cylindrical member and a plurality of arms extending radially outward from said cylindrical member, one end of each of said arms being attached to said encircling portion; and a housing including at least two members adapted to be attached to said engine, said housing surrounding the inner cylindrical member and elastomeric member, said housing being attached to the ends of said arms opposite said inner cylindrical member, the members of said housing having a gap therebetween in the longitudinal direction allowing compression of the outer housing.
Claim 6
Dependent Claim
20 words
The engine mount of claim 3 wherein said elastomeric material has a Shore A durometer of about 40 to 80.
Claim 7
Dependent Claim
31 words
The engine mount of claim 3 wherein said housing has a generally rectangular shape and said elastomeric member has four arms each said arms engaging a distinct corner of said housing.
Claim 8
Dependent Claim
24 words
The engine mount of claim 3 wherein the ratio between the spring rates measured in any two radial directions is about 0.8 to 1.2.
