Transmission packaging and rotor support structure
View Patent ↗A support structure for a rotor within a transmission system is provided. The cantilevered support structure is umbrella-shaped to create an area of space between the rotor and the main shaft where other vehicle components, such as a gear set or system of clutches, may be packaged. The cantilevered support structure may be a true cantilever or a steady-rested cantilever. The support structure maintains the rotor at a distance from the transmission main shaft to maintain torque within the system while compacting packaging requirements. A second cantilevered support structure is wineglass-shaped to create a second area of packaging space between the rotor and the main shaft. The support structures may be telescoped to further compact the transmission.
1. A support structure adapted to support a rotor in a vehicle transmission system having a rotatable main shaft, said support structure comprising:
an annular skirt portion rotatable with the main shaft, wherein said annular skirt portion includes a hollow shaft portion configured for telescopingly nesting with an adjacent support structure;
wherein said annular skirt portion maintains the rotor at a radial distance from a center axis of the transmission system; and
wherein said radial distance of said annular skirt portion is sufficient to create a packaging space between the rotor and the main shaft wherein at least one transmission component may be packaged.
2. The support structure of claim 1 wherein said annular skirt portion is shaped to substantially form one of an umbrella-shaped or a wineglass-shaped structure and further comprises a steady-rested cantilevered body.
3. The support structure of claim 1 wherein the packaging space is sufficiently spacious to house a system of clutches and/or gear sets.
4. A support arrangement adapted to support a pair of rotors in a vehicle transmission system having a rotatable main shaft, said support arrangement comprising:
first and second support structures for respectively supporting one of said pair of rotors;
wherein each of said first and second support structures is rotatable with the main shaft;
wherein each of said first and second support structures maintains a respective rotor at a respective radial distance from a center axis of the transmission system; and
wherein each said radial distance creates a packaging space between the respective rotor and the main shaft sufficient to retain at least one respective transmission component.
5. The support structure of claim 4 wherein each of said first and second support structures includes a shaft portion for facilitating the rotation of said support structures with the main shaft and at least partially maintaining said radial distance to create said packaging space.
6. The support structure of claim 5 wherein said shaft portions of each of said first and second support structures are sufficiently axially alignable so that said first and second support structures are compactable in said transmission system.
7. The support structure of claim 6 wherein at least one of said shaft portions is sufficiently hollow to receive the other of said shaft portions when said support structures are compacted.
8. A support structure adapted to support a rotor in a vehicle transmission system having a rotatable main shaft, said support structure comprising:
a first portion of the support structure having a shaft portion adapted to be connected to the main shaft for rotation with the main shaft, wherein said shaft portion is telescopingly nestable with an adjacent support structure; and
a second portion of the support structure configured as an annular skirt substantially as long as said rotor and extending axially from said first portion in an unsupported cantilever manner spaced sufficiently from the shaft portion to form an unobstructed packaging space for the length of the annular skirt which is open on one axial end thereof to house at least one transmission component within said packaging space.
9. The support structure of claim 8 wherein the support structure comprises a steady-rested cantilevered body.
10. The support structure of claim 8 wherein the packaging space is sufficiently spacious to house a system of clutches and/or gear sets.
11. The support structure of claim 8 including at least one bearing for positioning the support structure within the transmission system.
