Independently mounted electronic limited slip device for vehicle
View Patent ↗A device for use with a vehicle transmission system includes a housing having a clutch provided therein and a first member extending from the housing and configured for coupling to a vehicle differential. The first member includes a generally hollow tube configured to carry a rotatable shaft therein. The device does not include a second member for directly coupling the device to a transmission housing or to the differential.
1. An electronic limited slip device for a vehicle powertrain comprising:
a rotatable shaft configured to couple to a differential of a transmission;
a clutch housing having a clutch disposed therein and being configured to couple to an engine; and
a carrier generally disposed around the shaft and extending from the clutch housing;
wherein the carrier is configured to protect the rotatable shaft and is configured to couple to a transmission housing by a female member comprising channels and a male member comprising splines; and
wherein the female member is configured to receive the male member, and wherein the channels are configured to receive the splines.
2. The electronic limited slip device of claim 1 , wherein the carrier comprises the female member, and wherein the transmission housing comprises the male member.
3. The electronic limited slip device of claim 1 , wherein the carrier comprises the male member, and wherein the transmission housing comprises the female member.
4. The electronic limited slip device of claim 1 , wherein the electronic limited slip device is configured such that at least one of cooling channels, electronics, and other vehicle components may be mounted proximate the carrier.
5. The electronic limited slip device of claim 1 , wherein the clutch housing is configured to couple to the engine with at least one of fasteners and brackets.
6. A transmission system for a vehicle comprising:
a transmission comprising a differential and a transmission housing; and
an electronic limited slip device, comprising:
a rotatable shaft configured to couple to the differential;
a carrier generally disposed around the shaft and configured to couple to the transmission housing; and
a clutch disposed within a clutch housing, the clutch housing being configured to couple to an engine;
wherein the carrier extends from the clutch housing and is coupled to the transmission housing by a female member comprising channels and a male member comprising splines, wherein the female member received the male member, and wherein the channels received the splines.
7. The powertrain of claim 6 , wherein the carrier comprises the female member, and wherein the transmission housing comprises the male member.
8. The powertrain of claim 6 , wherein the carrier comprises the male member, and wherein the transmission housing comprises the female member.
9. The powertrain of claim 6 , wherein the electronic limited slip device is configured such that at least one of cooling channels, electronics, and other vehicle components may be mounted proximate the carrier.
10. The powertrain of claim 6 , wherein the electronic limited slip device is configured to couple to the engine with at least one of fasteners and brackets.
11. A method for providing an electronic limited slip device for a vehicle, the vehicle comprising a transmission and an engine, comprising:
providing a clutch housing and a carrier extending from the clutch housing;
disposing a clutch within the clutch housing;
disposing a shaft within the carrier, such that the carrier protects the shaft;
configuring the clutch housing to couple directly to the engine; and
providing the carrier with a splined member for coupling the carrier to a transmission housing.
12. The method of claim 11 , wherein providing the carrier with a splined member comprises providing a splined male member configured to be received by a female splined member of the transmission housing.
13. The method of claim 11 , wherein providing the carrier with a splined member comprises providing a splined female member configured to receive a male splined member of the transmission housing.
14. The method of claim 11 , wherein configuring the clutch housing to couple directly to the engine comprises at least one of providing fasteners or providing brackets.
15. The method of claim 11 , further comprising:
coupling the clutch housing to the engine; and
coupling the carrier to the transmission housing.
16. The method of claim 15 , further comprising providing the transmission housing with a splined member.
17. The method of claim 16 , wherein:
providing the carrier with a splined member comprises providing a splined male member;
providing the transmission housing with a splined member comprises providing a splined female member having channels; and
coupling the carrier to the transmission housing comprises disposing the male member into the female member, such that splines of the male member are received by channels of the female member.
18. The method of claim 16 , wherein:
providing the carrier with a splined member comprises providing a splined female member having channels;
providing the transmission housing with a splined member comprises providing a splined male member; and
coupling the carrier to the transmission housing comprises disposing the male member into the female member, such that splines of the male member are received by channels of the female member.
19. The method of claim 15 , wherein coupling the carrier to the transmission housing comprises at least one of coupling with fasteners and coupling with brackets.
20. The method of claim 15 , further comprising mounting at least one of cooling channels, electronics, or other vehicle components proximate the carrier.
