Abstract

A connecting rod includes an elongated body having a first connection end and a second connection end and an intermediate portion extending between the first connection end and the second connection end. The first connection end includes a cylindrical opening configured to receive a bushing and a link pin. The first connection end includes a first side face and a second side face each raised relative to the intermediate portion, the first side face includes a recessed slot that communicates with the cylindrical opening and an outer edge of the first side face. The slots can optionally be provided on the second side face, giving the connecting rod one or more slots on each side, which lubricate the link pin with splash oil.

First claim

What is claimed is:

1. A connecting rod, comprising:
an elongated body having a first connection end and a second connection end and an intermediate portion extending between the first connection end and the second connection end;
the first connection end including a cylindrical opening configured to receive a bushing and a link pin;
the first connection end including a first side face and a second side face each raised relative to the intermediate portion, the first side face and the second side face each facing in a direction of a center axis of the cylindrical opening, the first side face including a recessed slot that communicates with the cylindrical opening and an outer edge of the first side face.

2. The connecting rod according to claim 1 , wherein the recessed slot includes a pair of recessed slots.

3. The connecting rod according to claim 2 , wherein the pair of recessed slots extend from the opening toward the intermediate portion of the elongated body.

4. The connecting rod according to claim 3 , wherein the pair of recessed slots include a curled end that opens into the opening.

5. The connecting rod according to claim 1 , wherein the intermediate portion of the elongated body has an I-beam cross-section.

6. The connecting rod according to claim 1 , wherein the recessed slot is U-shaped.

7. The connecting rod according to claim 6 , wherein the U-shaped recessed slot includes a pair of side legs that opens to the outer edge of the first side face and a bridge portion connecting the pair of side legs, the bridge portion opens to the cylindrical opening.

8. The connecting rod according to claim 1 , wherein the recessed slot is curved.

9. The connecting rod according to claim 1 , wherein an entirety of the first connection end is formed integral with the intermediate portion.

10. The connecting rod according to claim 1 , wherein the first connection end is smaller than the second connection end.

11. The connecting rod according to claim 1 , wherein the first connection end is a small end.

12. The connecting rod according to claim 1 , wherein the second side face includes an additional recessed slot that communicates with the cylindrical opening and an outer edge of the second side face.

13. The connecting rod according to claim 12 , wherein the additional recessed slot includes a pair of recessed slots.

14. A connecting rod, comprising:
an elongated body having a first connection end and a second connection end and an intermediate portion extending between the first connection end and the second connection end;
the first connection end including a cylindrical opening configured to receive a bushing and a link pin;
the first connection end including a first side face and a second side face each raised relative to the intermediate portion, the first side face including a pair of recessed slots that each communicate with the cylindrical opening and an outer edge of the first side face.

15. The connecting rod according to claim 14 , wherein the pair of recessed slots extend from the cylindrical opening toward the intermediate portion of the elongated body.

16. The connecting rod according to claim 14 , wherein the pair of recessed slots include a curled end that opens into the opening.

17. The connecting rod according to claim 14 , wherein the intermediate portion of the elongated body has an I-beam cross-section.

18. The connecting rod according to claim 14 , wherein the first connection end is a small end.

19. The connecting rod according to claim 14 , wherein the second side face includes a pair of additional recessed slots that communicate with the cylindrical opening and an outer edge of the second side face.

20. The connecting rod according to claim 19 , wherein the pair of additional recessed slots extend from the cylindrical opening toward the intermediate portion of the elongated body.
