Abstract
A starter freewheel is provided. The starter freewheel has a first race, a second race, a wedging gap formed between the first and second races, at least one wedging element arranged in the wedging gap, and at least one further component. The further component is in rotary drive connection with one of the races. The component is formed by at least two sheet-metal parts connected to one another in sandwich-fashion. A freewheel arrangement having a starter freewheel of this kind is also provided.
Claims18
A freewheel arrangement for a drive train having a starter freewheel wherein the starter freewheel is a dry-running freewheel having a first race, and a second race, wherein the second race is in rotary drive connection with an output side of a starter and is supported on an output side of a driving unit on a fixed housing via a radial bearing arranged between the second race and a supporting part secured on the fixed housing, the freewheel arrangement further having a flexplate to transmit torque between the output side of the driving unit and the first race,
- wherein the flexplate includes a first sheet-metal part and a second sheet-metal part connected to one another in such a way that torque can be transmitted via just one of the two sheet-metal parts.
A freewheel arrangement for a drive train including a starter freewheel having a first race, a second race, a wedging gap formed between the first and second races, at least one wedging element arranged in the wedging gap, and at least one further component, which is in rotary drive connection with a corresponding one of the races, wherein the further component is formed by at least two sheet-metal parts connected to one another sandwich-fashion, wherein the two sheet-metal parts include a first sheet-metal part and a second sheet-metal part connected to one another in such a way that torque can be transmitted via just one of the two sheet-metal parts
- wherein the two sheet-metal parts are connected to one another with a damping layer placed in between, wherein the damping layer is softer and/or more flexible than the two sheet-metal parts.
A freewheel arrangement for a drive train including a starter freewheel having a first race, a second race, a wedging gap formed between the first and second races, at least one wedging element arranged in the wedging gap, and at least one further component, which is in rotary drive connection with a corresponding one of the races, wherein the further component is formed by at least two sheet-metal parts connected to one another sandwich-fashion, wherein the two sheet-metal parts include a first sheet-metal part and a second sheet-metal part connected to one another in such a way that torque can be transmitted via just one of the two sheet-metal parts
- wherein the two sheet-metal parts include a first sheet-metal part, and a second sheet-metal part having a side face that faces the first sheet-metal part is supported by at least 50% of the first sheet metal part.
A freewheel arrangement for a drive train including a starter freewheel having a first race, a second race, a wedging gap formed between the first and second races, at least one wedging element arranged in the wedging gap, and at least one further component, which is in rotary drive connection with a corresponding one of the races, wherein the further component is formed by at least two sheet-metal parts connected to one another sandwich-fashion, wherein the two sheet-metal parts include a first sheet-metal part and a second sheet-metal part connected to one another in such a way that torque can be transmitted via just one of the two sheet-metal parts,
- wherein sheet-metal of the second sheet-metal part has less thickness than sheet-metal of the first sheet-metal part.
