Abstract

A driveline assembly for a recreational vehicle may include an engine and an automated sequential transmission.

Claims (30)

1 . An automated sequential transmission, comprising:

a transmission housing;

a transmission input shaft accessible from an exterior of the transmission housing;

a clutch operatively coupled to the transmission input shaft; and

a hydraulic control unit (HCU), wherein at least a portion of the HCU is positioned vertically higher than a horizontal center of the clutch.

2 . The AST of claim 1 , wherein a majority of the HCU is positioned above the horizontal center of the clutch.

3 . The AST of claim 1 , wherein the entire HCU is positioned above the horizontal center of the clutch.

4 . The AST of claim 1 , wherein the HCU is positioned directly above the clutch.

5 . An automated sequential transmission, comprising:

a transmission housing;

a transmission input shaft accessible from an exterior of the transmission housing;

an assembly operatively coupled to the transmission input shaft, the assembly being driven by the transmission input shaft;

an oil pump operatively coupled to the assembly, the oil pump being driven by the assembly.

6 . The automated sequential transmission of claim 5 , further comprising:

a plurality of gears, and

wherein the transmission input shaft includes:

a clutch input shaft, and a clutch output shaft selectively engagable with the clutch input shaft;

wherein the assembly is operatively coupled to the clutch input shaft.

7 . The automated sequential transmission of claim 5 , wherein the assembly comprises:

a drive member operatively coupled to the transmission input shaft;

a driven member operatively coupled to the oil pump; and

a connecting member connecting the drive member to the driven member.

8 . The automated sequential transmission of claim 7 , wherein the drive member is a clutch mounted sprocket, wherein the driven member is an oil pump mounted sprocket, and wherein the connecting member is a chain connecting the clutch mounted sprocket to the oil pump mounted sprocket.

9 . The automated sequential transmission of claim 8 , wherein the oil pump comprises an oil pump shaft operatively coupled to the oil pump sprocket, and wherein a rotation of the transmission input shaft drives a rotation of the oil pump shaft.

10 . The automated sequential transmission of claim 9 , further comprising:

a clutch operatively coupled to the transmission input shaft, and wherein the assembly is coupled to the transmission input shaft prior to the clutch such that a rotation of the transmission input shaft drives the rotation of the oil pump shaft even if the clutch is disengaged.

11 . The automated sequential transmission of claim 5 , further comprising:

a clutch operatively coupled to the transmission input shaft, wherein the oil pump is positioned outside of an envelope of the clutch.

12 . The automated sequential transmission of claim 11 , wherein at least a portion of the oil pump is positioned below the clutch.

13 . The automated sequential transmission of claim 11 , wherein at least a portion of the oil pump is positioned directly below the clutch.
