Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
200 words
A mounting for an internal combustion engine with a transmission secured at one end of the engine, comprising bearing support means and torque support means for retaining the transmission and internal combustion engine at relatively fixed parts, said bearing support means including a first bearing support means and a second bearing support means, the weight of the transmission and the internal combustion engine being hangingly suspended solely by the first and second bearing support means, the first bearing support means is arranged above but not far from a horizontal plane that passes horizontally through the center of gravity of the engine as well as adjacent a vertical plane that passes vertically through the center of gravity of the internal combustion engine, the second bearing support means is attached to the internal combustion engine adjacent a side thereof that is opposite to the end with the transmission, and wherein the torque support means counteracts torque forces from the transmission and internal combustion and includes at least two horizontally directed torque support means that are provided offset to one another in height and wherein at least one of said two torque support means extends between fixed parts and the internal combustion engine.
Claim 2
Dependent Claim
200 words
A mounting for an internal combustion engine with a transmission secured at one end of the engine, comprising bearing support means and torque support means for retaining the transmission and internal combustion engine at relatively fixed parts, said bearing support means including a first bearing support means and a second bearing support means, the weight of the transmission and the internal combustion engine being hangingly suspended solely by the first and second bearing support means, the first bearing support means is arranged above but not far from a horizontal plane that passes horizontally through the center of gravity of the engine as well as adjacent a vertical plane that passes vertically through the center of gravity of the internal combustion engine, the second bearing support means is attached to the internal combustion engine adjacent a side thereof that is opposite to the end with the transmission, and wherein the torque support means counteracts torque forces from the transmission and internal combustion and includes at least two horizontally directed torque support means that are provided offset to one another in height and wherein at least one of said two torque support means extends between fixed parts and the internal combustion engine.
Claim 3
Dependent Claim
37 words
