Claims19
An improved gear reduction drive train comprising a power unit, said power unit having a motor shaft output, an output housing section, said output housing section having an opening and an input, said opening surrounding said input, means to drivingly connect said motor shaft output of said power unit to said input of said output housing section through said opening of said output housing section and said power unit being fixedly selectively bolted directly to said output housing section to allow differing selectable orientations between said power unit and said output housing section.
An improved gear reduction drive train comprising a power unit, said power unit having a motor shaft output, an output housing section, said output housing section having an opening and an input, said opening surrounding said input, means to drivingly connect said motor shaft output of said power unit to said input of said output housing section through said opening of said output housing section, means to connect said power unit to said output housing section to allow differing selectable orientations between said power unit and said output housing section, and said means to connect said power unit to said output housing section including a series of holes in said output housing section, said series of holes in said output housing section surrounding said opening, and said power unit being bolted to said output housing section via said holes.
An improved gear reduction drive train comprising a first power unit, said first power unit having a motor shaft output, an output housing section, said output housing section having an opening and an input, said opening surrounding said input, means to drivingly connect said motor shaft output of said first power unit to said input of said output housing section through said opening of said output housing section, means to connect said first power unit to said output housing section to allow differing selectable orientations between said first power unit and said output housing section, and a second power unit, said second power unit having a motor shaft output, a second output housing section, said second output housing section being substantially identical to said output housing section, said second output housing section having an opening and an input, said opening of said second output housing section surrounding said input of said second output housing section, means to drivingly connect said motor shaft output of said second power unit to said input of said second output housing section through said opening of said second output housing section, and means to connects said second power unit to said second output housing section to allow differing selectable orientations between said second power unit and said second output housing section.
An improved gear reduction drive train comprising a power unit, said power unit having a motor shaft output and mounting bolt means, said mounting bolt means having a certain number, an output housing section, said output housing section having an input opening, and an input and an axle output, said opening surrounding said input, a series of holes, said series of holes being in said output housing section surrounding said opening, the number of said series of holes being more numerous than said certain number of said mounting bolt means of said power unit so as to allow said power unit to be connected to said output housing section in various differing selectable orientations, and said power unit being bolted to said output housing section via said mounting bolt means and said series of holes with said motor shaft output of said power unit connected to said input of said output housing section through said opening.
An improved gear reduction drive train comprising a first power unit, said first power unit having a motor shaft output and mounting bolt means, said mounting bolt means of said first power unit being certain in number, a first output housing section, said first output housing section having an input opening and an input and an axle output, said opening of said first output housing section surrounding said input of said first output housing section, a first series of holes, said first series of holes being in said first output housing section surrounding said opening of said first input housing section, the number of said first series of holes being more numerous than said certain number of said mounting bolt means of said first power unit so as to allow said first power unit to be connected to said first output housing section in various differing selectable orientations, said first power unit being bolted to said first output housing section via said mounting bolt means of said first power unit and said first series of holes with said motor shaft output of said first power unit connected to said input of said first output housing section through said opening in said first output housing section, a second power unit, said second power unit having a motor shaft output and mounting bolt means, said mounting bolt means of said second power unit being certain in number, a second output housing section, said second output housing section being substantially identical to said first output housing section, said second output housing section having an input opening and an input and an axle output, said opening of said second output housing section surrounding said input of said second output housing section, a second series of holes, said second series of holes being in said second output housing section surrounding said opening of said second output housing section, the number of said second series of holes being more numerous than said certain number of said mounting bolt means of said second power unit so as to allow said second power unit to be connected to said second output housing section in various differing selectable orientations, and said second power unit being bolted to said second output housing section via said mounting bolt means of said second power unit and said second series of holes with said motor shaft output of said second power unit connected to said input of said second output housing section through said opening in said second output housing section.
An improved gear reduction drive train comprising a first power unit, said first power unit having a motor shaft output, an output housing section, said output housing section having an opening and an input, said opening surrounding said input, means to drivingly connect said motor shaft output of said first power unit to said input of said output housing section through said opening of said output housing section, means to connect said first power unit to said output housing section to allow differing selectable orientations between said first power unit and said output housing section, and the drive train being utilized with a vehicle, a second power unit for the vehicle and said second power unit being substantially identical to said first power unit.
An improved gear reduction drive train comprising a first power unit, said first power unit having a motor shaft output, an output housing section, said output housing section having an opening and an input, said opening surrounding said input, means to drivingly connect said motor shaft output of said first power unit to said input of said output housing section through said opening of said output housing section, means to connect said first power unit to said output housing section to allow differing selectable orientations between said first power unit and said output housing section, a second power unit, and said second power unit being substantially identical to said first power unit.
