Drive-wheel hub for a motor vehicle
First Claim
1. A driven wheel hub for a motor vehicle intended to be attached by a bolt to a driving member having a tapped hole having an entry point, said driven wheel hub comprising:
- a hub body having an outboard side, an inboard side, and an axial cavity extending through said hub body;
a bearing surface on said outboard side of said hub body for bearing a head of the bolt, wherein said axial cavity at has a portion delimited at said outboard side by said bearing surface and at said inboard side, when said hub body is to be connected to the driving member, by the entry point to the tapped hole of the driving member, said portion of said axial cavity having a front half on said inboard side and a rear half adjacent to said bearing surface;
means on said hub body for ensuring that said hub body rotates together with the driving member when the driving member is attached to said hub body;
guide means within said axial cavity of said hub body, between said bearing surface and the location of the entry point of the tapped hole when the driving member is to be connected to said hub body for guiding the bolt, said guide means being located in said front half of said portion of said axial cavity.

Abstract
A driven-wheel hub (18) includes an axial cavity (36) for the passage of the body of a bolt (16) for fixing a driving member (14) onto the hub. This member (14) is provided with a tapped hole (17) into which the threaded end (16A) of the bolt body is screwed. The cavity (36) has a diameter which is very much larger than the diameter of the bolt body and is bordered at its rear end by a bearing surface (40) for the head (45) of the bolt. The hub (18) furthermore includes a way of ensuring that it rotates as one with the driving member. A guide for guiding the bolt (37) are provided in the cavity (36) between the said bearing surface (40) and the entry to the tapped hole (15). The guides (38) are spaced away from the said bearing surface (40) along the axis of the hub.

16. A driven wheel hub arrangement comprising:
-
a hub body having an axis of rotation and an axial cavity extending through said hub body from an inboard side of said hub body to an outboard side of said hub body, said hub body being intended to be connected to a driving member with a bolt; a bolt bearing surface defined on said outboard side of said hub body, said bolt bearing surface being intended to receive the head of a bolt when the bolt connects said hub body to the driving member, said axial cavity extending from said bolt bearing surface to said inboard side of said hub body; a driving member rotation connection formed on said hub body and adapted to connect said hub body with the driving member in rotation when the driving member is connected to said hub body with the bolt; said hub body having a bolt guide in said axial cavity, said bolt guide being spaced from said bolt bearing surface in the direction of said inboard side of said hub body when the bolt connects the driving member to the hub body such that said driving member rotation connection connects with the driving member, and said bolt guide is spaced from an outboard end of the driving member in the outboard direction; wherein said bolt guide has an inner diameter that is smaller than the inner diameter of said axial cavity along a portion between said bolt bearing surface and said bolt guide. - View Dependent Claims (17, 18, 19, 20, 21)
