Spindle hub spacer interconnection

An interconnection between a spindle and a surrounding part, said surrounding part having a planar section with first and second surfaces and a through hole extending from the first surface to the second surface,

• the interconnection comprising a hub spacer, said hub spacer having a central hole, a first section having surrounding outer surface and a width to allow the first section to be inserted into the through hole in the planar section, and a second section having a width that is greater than the width of said first section wherein said second section defines a shoulder between said first and second sections, said central hole being formed with inwardly extending protrusions,
• the spindle being formed with outwardly extending protrusions, said inwardly extending protrusions of said hub spacer drivingly engaging said outwardly extending protrusions of the spindle, said surrounding outer surface of said first section being formed with outwardly extending protrusions, the through hole in the planar section being formed with inwardly extending protrusions extending along the full length of the through hole, said first surface of the planar section contacting said shoulder,
• said outwardly extending protrusions of said surrounding outer surface of said first section drivingly engaging said inwardly extending protrusions of the through hole in the planar section,
• a capture means, said capture means being on the second surface whereby said capture means engages the spindle so as to hold the planar section in contact with said shoulder.

An interconnection between a spindle and a surrounding part, said surrounding part having a planar section with first and second surfaces, a through hole extending from the first surface to the second surface, and a depth,

• the interconnection comprising a hub spacer, said hub spacer having a central hole and a depth, a first section having surrounding outer surface and a width to allow the first section to be inserted into the through hole in the planar section, and a second section having a width that is greater than the width of said first section wherein said second section defines a shoulder between said first and second sections, said central hole being formed with inwardly extending protrusions,
• the spindle being formed with outwardly extending protrusions, said inwardly extending protrusions of said hub spacer drivingly engaging said outwardly extending protrusions of the spindle, said depth of said planar section being less than said depth of said hub spacer,
• said surrounding outer surface of said first section being formed with outwardly extending protrusions, the through hole in the planar section being formed with inwardly extending protrusions extending along the full length of the through hole, said first surface of the planar section contacting said shoulder,
• and said outwardly extending protrusions of said surrounding outer surface of said first section drivingly engaging said inwardly extending protrusions of the through hole in the planar section.

An interconnection between a spindle and a surrounding part, said surrounding part having a planar section with first and second surfaces and a through hole extending from the first surface to the second surface,

• the interconnection comprising a hub spacer, said hub spacer having a central hole, a first section having surrounding outer surface and a width to allow the first section to be inserted into the through hole in the planar section, and a second section having a width that is greater than the width of said first section wherein said second section defines a shoulder between said first and second sections, said central hole being formed with inwardly extending protrusions,
• the spindle being formed with outwardly extending protrusions, said inwardly extending protrusions of said hub spacer drivingly engaging said outwardly extending protrusions of the spindle,
• said surrounding outer surface of said first section being formed with outwardly extending protrusions, the through hole in the planar section being formed with inwardly extending protrusions extending along the full length of the through hole, said first surface of the planar section contacting said shoulder,
• said outwardly extending protrusions of said surrounding outer surface of said first section drivingly engaging said inwardly extending protrusions of the through hole in the planar section,
• a nut, said nut being on the second surface of the planar section for said nut to engage the spindle so as to hold the planar section about said first section of said hub spacer in physical contact with said shoulder.
