The present disclosure relates to a clamp yoke assembly.
A vehicle may be provided with a clamp yoke that is coupled to a shaft that aids in the transmission of a torque to a component of the vehicle. A bolt may be inserted into the clamp yoke that applies a force to the clamp yoke to deform the clamp yoke about the shaft to operatively connect the clamp yoke to the shaft.
Accordingly, it is desirable to provide a reliable connection between the clamp yoke and the steering shaft or pinion shaft.
According to an embodiment of the present disclosure, a shaft assembly is provided. The shaft assembly includes a yoke defining a first bore that extends from a first face towards a second face along a first axis. The first bore has an inner surface that defines a key that extends towards the first axis and a first bore first flat that extends along the first axis and is spaced apart from the key. A second bore that extends from a third face towards a fourth face along a second axis that is disposed transverse to the first axis. The third face and the fourth face each extend between the first face and the second face.
According to another embodiment of the present disclosure, a shaft assembly is provided. The shaft assembly includes a yoke having a first face, a second face disposed opposite the first face, a third face extending between the first face and the second face, a fourth face disposed opposite the third face and extending between the first face and the second face, and a fifth face extending between the first face, the second face, the third face, and the fourth face. The yoke defines a first bore has a key and a first bore first flat that extends from the first face towards the second face along a first axis.
These and other advantages and features will become more apparent from the following description taken in conjunction with the drawings.
The subject matter of the present disclosure is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features, and advantages of the present disclosure are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
Referring now to the Figures, where the present disclosure will be described with reference to specific embodiments, without limiting the same, it is to be understood that the disclosed embodiments are merely illustrative of the present disclosure that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

The outer surface 30 defines a shaft notch 40 that is disposed proximate the first shaft end 32. The shaft notch 40 axially extends along the first axis 36 and extends across the shaft 20 in a direction that is transverse to the first axis 36. The shaft notch 40 defines a generally flat surface that is disposed substantially parallel to the first axis 36.
The shaft notch 40 is axially disposed between a first shoulder 42 and a second shoulder 44 of the shaft 20. The first shoulder 42 is disposed proximate the first shaft end 32 and is disposed generally perpendicular to the first axis 36. The second shoulder 44 is disposed between the shaft notch 40 and the second shaft end 34. The second shoulder 44 is disposed generally perpendicular to the first axis 36.
The shaft 20 may have a variable diameter or cross-sectional form over the length of the shaft 20 along the first axis 36. For example, the shaft 20 may have a first diameter between the first shoulder 42 and the first shaft end 32. The shaft 20 may have a second diameter between the first shoulder 42 and the shaft notch 40 and/or the second shoulder 44 that is greater than the first diameter. The shaft 20 may have a third diameter between the second shoulder 44 and the second shaft end 34 that is greater than the second diameter.

The yoke 22 defines a first bore 70 that extends along the first axis 36, a second bore 72 that extends along a second axis 74 that is disposed transverse to the first axis 36, and a notch 76.
The first bore 70 extends from the first face 60 towards the second face 62 along the first axis 36. The first bore 70 has a noncircular cross-sectional profile. The first bore 70 has an inner surface 80 that defines a key 82, a first bore first flat 84, and a first bore second flat 86. The inner surface 80 has a noncircular cross-sectional profile and the third flat 54 is spaced apart from the inner surface 80 of the first bore 70.
The key 82 extends from the inner surface 80 towards the first axis 36. The key 82 extends along the inner surface 80 from the first face 60 towards the second face 62. The key 82 is arranged to engage the outer surface 30 of the shaft 20, as shown in
The key 82 includes a first key surface 90, a second key surface 92, and a third key surface 94. The third key surface 94 extends between the first key surface 90 and the second key surface 92. The third key surface 94 of the key 82 engages the outer surface 30 of the shaft 20. The first key surface 90 and the second key surface 92 may become progressively closer to each other in a direction that extends from the inner surface 80 towards the third key surface 94.
The first bore first flat 84 is circumferentially spaced apart from the key 82. The first bore first flat 84 extends from the first shaft end 32 towards the second shaft end 34 along the first axis 36. The first bore first flat 84 is disposed generally parallel to the fifth face 68. The first bore first flat 84 is arranged to engage the first flat 50 of the shaft 20.
The first bore second flat 86 is circumferentially spaced apart from the key 82 and the first bore first flat 84. The first bore second flat 86 extends from the first shaft end 32 towards the second shaft and 34 along the first axis 36. The first bore second flat 86 is angled towards the key 82 in a direction that extends towards the fifth face 68. In such an arrangement, the first bore second flat 86 is disposed in a nonparallel and non-perpendicular relationship with respect to the first bore first flat 84. The first bore second flat 86 is arranged to engage the second flat 52 of the shaft 20.
The second bore 72 extends from the third face 64 towards the fourth face 66 along the second axis 74. The second bore 72 is arranged to receive a fastener 100 that extends along the second axis 74. The fastener 100 engages the flat surface of the shaft notch 40 to secure the shaft 20 and the yoke 22, as will be described in further detail.
The notch 76 extends from the first face 60 towards the second face 62 along the first axis 36. The notch 76 extends from the fifth face 68 towards the first bore 70 and/or the second bore 72 along an axis that is disposed transverse to both the first axis 36 and the second axis 74. The notch 76 extends at least partially through the second bore 72 and extends to the first bore 70.
