DETAILED DESCRIPTION
Referring to the drawings, wherein like reference numbers refer to like components, FIG. 1 shows a transmission 10 within a vehicle 12. The transmission 10 is an automatic transmission which includes a housing 14, a rotor shaft 16, a lever assembly 18, a bracket assembly 20, a shifter 22, and a shift cable assembly 24. The rotor shaft 16 is rotatably disposed in the housing 14 and is configured to provide a plurality of transmission driving ranges, or modes, e.g., park, reverse, neutral, drive, low, and the like. The transmission 10 is configured such that a rotational position of the rotor shaft 16, with respect to the housing 14, determines which of the driving ranges is selected. Each of the positions causes the transmission 10 to operate in a respective one of the driving ranges.
The lever assembly 18 operatively connects the rotor shaft 16 and the shift cable assembly 24. The shift cable assembly 24 is configured to cause rotational movement of the rotor shaft 16 relative to the housing 14. As such, rotation of the rotor shaft 16 provides a plurality of driving range positions, which correspond to a respective one of the predetermined driving ranges.
Referring to FIGS. 1 and 2, the shift cable assembly 24 is operatively attached to the housing 14 via the bracket assembly 20 and the lever assembly 18. The shift cable assembly 24 is also operatively attached to the shifter 22. The shifter 22, in turn, may be operatively connected to a shift lever configured for being moved by a user of the vehicle 12, or by an electric motor assembly, to select the desired operating mode. The bracket assembly 20 is operatively attached to the housing 14. The shift cable assembly 24 is operatively attached to the bracket assembly 20.
Referring to FIGS. 1, 2, and 4-6, the shift cable assembly 24 includes a cable portion 26, a connecting rod 28, and a connector 30. The cable portion 26 is operatively connected to the connecting rod 28 and the connector rod 28 is operatively connected to the lever assembly 18. More specifically, the cable portion 26 is operatively connected between the shifter 22 and the connector 30. A sheath 32 surrounds the cable portion 26 to allow movement of the cable portion 26 relative to the sheath 32. The connector 30 defines a depression 34 extending about an exterior thereof The connector 30 is operatively attached to the sheath 32 and is configured for attachment to the bracket assembly 20, as explained in more detail below. Therefore, when the shift cable assembly 24 is attached to the lever assembly 18, the bracket assembly 20, and the shifter 22, an axial movement of the cable 26 relative to the sheath 32, in turn, causes a corresponding axial movement of the connector rod 28 to move the lever assembly 18 and rotate the rotor shaft 16 to the desired operating mode.
With continued reference to FIGS. 1, 2, and 4-6, the bracket assembly 20 is configured such that the connector 30 of the shift cable assembly 24 is installable in any desired orientation, i.e., from the bottom, from the top, from the front, from the back, and the like. Various terms such as “bottom,” “top,” “front,” “back,” and the like are used herein to describe the bracket assembly 20 as oriented in the vehicle 12 with respect to the ground, to facilitate a clear description. However, the use of these words is not intended to be unnecessarily limiting, and it is specifically contemplated that the arrangement can assume various orientations.
Referring to FIGS. 1-6, the bracket assembly 20 includes a first section 36 and a second section 38. As will be explained in more detail below, the second section 38 is pivotally attached to the first section 36 to provide a secondary locking feature to retain the connector 30 of the shift cable assembly 24 to the bracket assembly 20. The first section 36 is attached by the rivet 58 to the second section 38, as shown in FIGS. 1 and 2, and receives the connector 30 therein. The second section 38 is pivoted relative to the first section 36, as illustrated in FIG. 6, such that the connector 30 is captured between the first section 36 and the second section 38, as shown in FIGS. 1, 2, and 6. The second section 38 is subsequently attached to the first section 36 with the fastener 46 secured to the weld nut 64 to prevent pivoting, as illustrated in FIGS. 1, 2, and 6.
Referring to the Figures, the first section 36 includes a base portion 40 and a first flange 42. The base portion 40 defines at least one first attachment hole 44. The base portion 40 defines two first attachment holes 44. It should be appreciated that more or less first attachment holes 44 may be provided. A fastener 46 is inserted through the first attachment holes 44 and secures the first section 36 to the housing 14 of the transmission 10, as shown in FIGS. 1 and 2. The first flange 42 extends from the base portion 40 and presents an edge 48. Referring specifically to FIGS. 4-6, the edge 48 defines a groove 50 having a profile generally corresponding to the depression 34 of the connector 30. More specifically, the groove 50 is configured to receive the connector 30 therein such that the depression 34 of the connector 30 and the first flange 42 are generally intermeshed with one another. The groove 50 is generally U-shaped and the connector 30 and corresponding depression 34 are generally cylindrical. A recess 51 is also defined in the first flange 42. The recess 51 opens to the groove 50 and may face the edge 48. The recess 51 may be generally rectangular in shape.
The connector 30 may include a flexible attachment clip 52 which is axially disposed, adjacent the depression 34. The flexible attachment clip 52 includes a spring portion 54 and a tab 56. The spring portion 54 is configured to be seated within the depression 34 and also snap into the axially adjacent groove 50 defined in the first flange 42. The tab 56 extends from the spring portion 54. The tab 56 is configured to be received by the recess 51 as the spring portion 54 is received by the groove 50. Therefore, as best shown in FIG. 6, when the connector 30 is inserted into the groove 50, the tab 56 fits into recess 51 such that the spring clip 52 and the tab 51 become intermeshed with, or otherwise become interlocked with, the first flange 42. Additionally, the tab 56 may prevent rotation of the connector 30 with respect to the first flange 42. Accordingly, the spring clip 52 and the tab 51 cooperate to axially and radially retain the connector 30 to the first flange 42 of the first section 36.
The second section 38 is pivotally attached to the first section 36 such that the second section 38 pivots relative to the first section 36, as indicated by 57. The second section 38 may be pivotally attached to the first section 36 with a rivet 58 to provide a pivoting hinge. It should be appreciated that other pivoting mechanisms may also be used. The second section 38 includes a leg portion 60 and a second flange 66 which extends from the leg portion 60. The second flange 66 presents a support surface 67 and is configured for supporting the connector 30, should the connector 30 become unsnapped from the groove 50. Referring to FIGS. 1-3, 5, and 6, the leg portion 60 of the second section 38 is pivotally attached to the base portion 40 of the first section 36 with the rivet 58. The second section 38 pivots relative to the first section 36 between a closed position, as illustrated in FIGS. 1-3, and an open position, as illustrated in FIGS. 4-6. When the second section 38 is in the closed position, the support surface 67 of the second flange 66 extends in generally perpendicular relationship to the first flange 42, proximate the edge 48, such that the support surface 67 of the second flange 66 is positioned against the connector 30, when the shift cable assembly 24 is inserted in the groove 50. Positioning the second flange 66 against the connector 30, when the bracket assembly 20 is in the closed position, prevents the connector 30 from disengaging from the groove 50 of the first flange 42. Therefore, the connector 30 may be inserted into the groove 50 in any orientation, i.e., from the top, bottom, front, back, and the like, based on the orientation of the groove 50 with respect to the transmission 10. Referring to FIGS. 4 and 5, the connector 30 is inserted from the bottom in an upward direction, as indicated by the directional arrow 70. Therefore, the second flange 66 functions to capture the connector 30, should the spring clip 52 become unsnapped from the groove 50. Likewise, when the second section 38 is in the open position, the second flange 66 is rotated away from first flange 42 and the edge 48 to allow insertion of the connector 30 into the groove 50.
The leg portion 60 and the base portion 40 each define a second attachment hole 62. When the second section 38 is in the closed position, the leg portion 60 overlaps with the base portion 40 of the first section 36 such that the second attachment holes 62 are aligned with one another. A fastener 46 is inserted through the aligned second attachment holes 62 to retain the second section 38 in the closed position. Additionally, a weld nut 64 may be attached to the base portion 40. Accordingly, the fastener 46 extends through the aligned second attachment holes 62 and into the weld nut 64 to secure the leg portion 60 to the base portion 40.
While the best modes for carrying out the invention have been described in detail, those familiar with the art to which this invention relates will recognize various alternative designs and embodiments for practicing the invention within the scope of the appended claims.
