Carbon composite tube yoke

Abstract

A tube yoke used in a propeller shaft, which provides power transmission in vehicles. The tube yoke has a body made of composite pre-preg material, which has an extension surface in the form of a yoke on one end and in the form of a tube on the other end, which is attached to the propeller shaft tube by bonding or tight fitting.

Claims

1. An assembly comprising: a propeller shaft having a propeller tube shaft; and a tube yoke comprising a body formed of a composite pre-preg material, said body having an extension surface in the form of a yoke at one end and in the form of a tube on the other end, which is attached to the propeller tube shaft by bonding or tight fitting.

2. The assembly of claim 1, wherein the extension surface has a shoulder thereon, the shoulder being of a step form.

3. The assembly of claim 1, wherein the extension surface has a shoulder thereon, the shoulder adapted to connect said body with the propeller tube shaft.

4. The assembly of claim 1, wherein the extension surface has a hole therein so as to allow said body to connect to the propeller tube shaft.

5. The assembly of claim 4, wherein the hole extends to a base of the yoke of the extension surface.

6. The assembly of claim 4, wherein a gap is formed between the hole and the propeller shaft tube, the gap adapted to receive an adhesive therein in order to connect said body with the propeller tube shaft.

7. The assembly of claim 1, wherein a gap is formed between the extension surface and the propeller tube shaft, the gap adapted to allow an adhesive to fill between the extension surface and the propeller tube shaft in order to connect said body with the propeller tube shaft.

DETAILED DESCRIPTION OF THE INVENTION

(6) In this detailed description, the preferred alternatives of the inventive tube yoke are described only for clarifying the subject matter such that no limiting effect is created.

(7) In FIG. 1, an illustrative view of the inventive tube yoke is given. Accordingly, the tube yoke mainly comprises a body (10) made of composite pre-preg material, which has a yoke (11) form at one end and a tubular extension surface (14) with a hole (12) at the other end.

(8) The body (10) which forms the main structure of the inventive tube yoke is made of composite pre-preg material and one end is in the form of a yoke (11). The other end has a tubular extension surface (14).

(9) A shoulder (13) can be found on the extension surface (14) in the form of a step or set so as to connect the body (10) with the propeller shaft tube (B). As seen in FIG. 2, the propeller shaft tube (B) is placed on the extension surface (14) by means of the shoulder (13) and combined with the body (10) by means of bonding or tight fitting. In this combining process, a gap (15) is formed between the extension surface (14) and the propeller shaft tube (B) so as to allow the adhesive to be filled between the extension surface (14) and the propeller shaft tube (B) to connect the said body (10) with the propeller shaft tube (B).

(10) As seen in FIG. 3, in the alternative embodiment of the invention, the extension surface (14) of the body (10) which has a yoke (11) at one end and a tubular extension surface (14) at the other end may be in flat form. A hole (12) can be found in said extension surface (14) to connect the body (10) with the propeller shaft tube (B) used in the propeller shaft and said hole (12) may extend up to the yoke base (111). In this combining process, a gap (15) can be formed between the hole (12) and the propeller shaft tube (B) so as to allow the adhesive to be filled between the hole (12) and the propeller shaft tube (B). As seen in FIG. 4, the propeller shaft tube (B) is passed through the hole (12) in the extension surface (14), it is combined with the body (10) by means of the adhesive filled into said gap (15).
