Abstract

A mounting assembly for a blade of a motor grader includes a mounting bracket having a groove, at least one first bore, and a second bore. The mounting assembly includes a wear element disposed in the groove. The wear element includes at least one recess. The wear element is adapted to slidably receive a portion of the blade thereon. The mounting assembly also includes a retention pin disposed in the at least one first bore. The retention pin includes an aperture provided therein. The retention pin is adapted to engage the at least one recess provided on the wear element to limit longitudinal movement of the wear element within the groove. The mounting assembly further includes a lynch pin disposed in each of the second bore and the aperture to limit axial movement of the retention pin within the at least one first bore.

First claim

What is claimed is:

1. A mounting assembly for a blade of a motor grader, the mounting assembly comprising:
a mounting bracket adapted to be mounted to a frame of the motor grader, the mounting bracket including:
a groove extending along a longitudinal axis of the mounting bracket;
at least one first bore provided adjacent to the groove; and
a second bore provided adjacent to the at least one first bore;
a wear element disposed in the groove, the wear element including at least one recess provided thereon, the at least one recess adapted to be axially aligned with respect to the at least one first bore provided in the mounting bracket, wherein the wear element is adapted to slidably receive a portion of the blade thereon;
a retention pin disposed in the at least one first bore, the retention pin including an aperture provided therein, the aperture adapted to be axially aligned with respect to the second bore provided in the mounting bracket, the retention pin adapted to engage the at least one recess provided on the wear element, wherein the retention pin is adapted to limit longitudinal movement of the wear element within the groove; and
a lynch pin disposed in each of the second bore provided in the mounting bracket and the aperture provided in the retention pin, wherein the lynch pin is adapted to limit axial movement of the retention pin within the at least one first bore.

2. The mounting assembly of claim 1 ,
wherein the at least one recess is at least one first recess provided on a first side of the wear element, and
wherein the wear element is adapted to slidably receive the portion of the blade in a second recess on a second side of the wear element opposite the first side.

3. The mounting assembly of claim 1 wherein the wear element has opposing ends in a longitudinal direction that are entirely exposed when the wear element is disposed in the groove of the mounting bracket and the mounting bracket is mounted to the frame of the motor grader.

4. The mounting assembly of claim 2 , wherein the lynch pin is provided in the extension portion.

5. The mounting assembly of claim 1 , wherein the groove has a substantially Y-shaped cross-sectional configuration.

6. The mounting assembly of claim 1 , wherein the wear element has a substantially Y-shaped cross-sectional configuration.

7. The mounting assembly of claim 1 , wherein the at least one first bore is substantially perpendicular with respect to the groove.

8. The mounting assembly of claim 1 , wherein the at least one first bore is substantially perpendicular with respect to each of the second bore and the aperture.

9. The mounting assembly of claim 1 , wherein the portion of the blade slidably received on the wear element limits lateral movement of the wear element with respect to the groove.

10. The mounting assembly of claim 1 , wherein the mounting bracket is mounted to the frame of the motor grader using a mounting stem and a support member.

11. A blade assembly for a motor grader, the blade assembly comprising:
a blade adapted to engage a work surface;
a support member coupled to a circle member of the motor grader; and
a mounting assembly coupled to each of the support member and the blade, the mounting assembly including:
a mounting bracket adapted to be mounted to the support member, the mounting bracket including:
a groove extending along a longitudinal axis of the mounting bracket;
at least one first bore provided adjacent to the groove; and
a second bore provided adjacent to the at least one first bore;
a wear element disposed in the groove, the wear element including at least one recess provided thereon, the at least one recess adapted to be axially aligned with respect to the at least one first bore provided in the mounting bracket, wherein the wear element is adapted to slidably receive a portion of the blade thereon;
a retention pin disposed in the at least one first bore, the retention pin including an aperture provided therein, the aperture adapted to be axially aligned with respect to the second bore provided in the mounting bracket, the retention pin adapted to engage the at least one recess provided on the wear element, wherein the retention pin is adapted to limit longitudinal movement of the wear element within the groove; and
a lynch pin disposed in each of the second bore provided in the mounting bracket and the aperture provided in the retention pin, wherein the lynch pin is adapted to limit axial movement of the retention pin within the at least one first bore.

12. The blade assembly of claim 11 ,
wherein the at least one recess is at least one first recess provided on a first side of the wear element, and
wherein the wear element is adapted to slidably receive the portion of the blade in a second recess on a second side of the wear element opposite the first side.

13. The blade assembly of claim 1 , wherein the wear element has opposing ends in a longitudinal direction that are entirely exposed when the wear element is disposed in the groove of the mounting bracket and the mounting bracket is mounted to the frame of the motor grader.

14. The blade assembly of claim 11 , wherein the at least one first bore is substantially perpendicular with respect to the groove.

15. The blade assembly of claim 11 , wherein the at least one first bore is substantially perpendicular with respect to each of the second bore and the aperture.

16. The blade assembly of claim 11 , wherein the mounting bracket is mounted to the support member using a mounting stem.

17. A motor grader comprising:
a frame;
a circle member mounted to the frame;
a pair of arms extending from the circle member;
a support member movably coupled to the pair of arms;
a blade adapted to engage a work surface; and
a mounting assembly adapted to mount the blade to the support member, the mounting assembly including:
a mounting bracket adapted to be mounted to the support member, the mounting bracket including:
a groove extending along a longitudinal axis of the mounting bracket;
at least one first bore provided adjacent to the groove; and
a second bore provided adjacent to the at least one first bore;
a wear element disposed in the groove, the wear element including at least one recess provided thereon, the at least one recess adapted to be axially aligned with respect to the at least one first bore provided in the mounting bracket, wherein the wear element is adapted to slidably receive a portion of the blade thereon;
a retention pin disposed in the at least one first bore, the retention pin including an aperture provided therein, the aperture adapted to be axially aligned with respect to the second bore provided in the mounting bracket, the retention pin adapted to engage the at least one recess provided on the wear element, wherein the retention pin is adapted to limit longitudinal movement of the wear element within the groove; and
a lynch pin disposed in each of the second bore provided in the mounting bracket and the aperture provided in the retention pin, wherein the lynch pin is adapted to limit axial movement of the retention pin within the at least one first bore.

18. The motor grader of claim 17 ,
wherein the wear element has opposing ends in a longitudinal direction that are entirely exposed when the wear element is disposed in the groove of the mounting bracket,
wherein the at least one recess is at least one first recess provided on a first side of the wear element, and
wherein the wear element is adapted to slidably receive the portion of the blade in a second
