Abstract
A pivot pin is provided for pivotally connecting a hydraulic actuator to a power machine. The pivot pin includes a first pin part having a first bolt-receiving passageway. The pivot pin also includes a second pin part having a second bolt-receiving passageway. In addition, the pivot pin includes a bolt that extends through and is engaged by the first and second bolt-receiving passageways.
Claims16
A pivot pin for pivotally connecting a hydraulic actuator to a power machine, comprising:
- a first pin part having a first bolt-receiving passageway;
- a second pin part having a second bolt-receiving passageway;
- a bolt that extends through and is engaged by the first and second bolt-receiving passageways;
- and
- wherein the first pin part further comprises a third bolt-receiving passageway, the second pin part further comprises a fourth bolt-receiving passageway, and the pivot pin further comprises a second bolt that extends through and is engaged by the third and fourth bolt-receiving passageways.
A pivot pin for pivotally connecting a hydraulic actuator to a power machine, comprising:
- a first pin part having a first bolt-receiving passageway;
- a second pin part having a second bolt-receiving passageway;
- a bolt that extends through and is engaged by the first and second bolt-receiving passageways;
- and
- wherein at least one of the first and second bolt-receiving passageways is a bolt-receiving groove.
A hydraulic actuator for extending and retracting a telescoping lift arm associated with a power machine, the hydraulic actuator comprising:
- an end member that includes:
- an internal chamber;
- a first inset that includes a first bolt-receiving aperture;
- a second inset that includes a second bolt-receiving aperture, the first and second insets being positioned such that the first and second bolt-receiving apertures are aligned with one another;
- and
- a bolt path formed through the end member between the fist and second bolt-receiving apertures, the bolt path being displaced from the internal chamber.
A power machine, comprising:
- a frame;
- a plurality of ground engaging wheels supporting the frame;
- a cab operably coupled to the frame and defining an operator compartment;
- an engine operably coupled to the wheels;
- a telescoping lift arm operably coupled to the frame and including first and second rotation apertures that are positioned opposite one another;
- and
- a hydraulic cylinder for extending and retracting the telescoping lift arm, wherein the hydraulic cylinder includes an end member having an internal chamber formed therein, wherein the end member also includes:
- a first inset that includes a first bolt-receiving aperture;
- a second inset that includes a second bolt-receiving aperture, wherein a portion of the internal chamber is positioned between the first and second insets, and wherein the first and second insets are positioned such that the first and second bolt-receiving apertures are aligned with one another;
- a bolt path formed through the end member between the fist and second bolt-receiving apertures, the bolt path being displaced from the internal chamber;
- a first pin part having a first bolt-receiving passageway, the first pin part being engaged within the first inset and pivotally received within the first rotation aperture;
- a second pin part having a second bolt-receiving passageway, the second part being engaged within the second inset and pivotally received within the second rotation aperture;
- and
- a bolt that extends through the first bolt-receiving passageway, through the first bolt-receiving aperture, through the bolt path, through the second bolt-receiving aperture, and through the second bolt-receiving passageway.
