Jacking system for a utility vehicle

摘要

A jacking system for a utility vehicle comprises a telescopic beam suspended under the vehicle body which is extractable in a generally horizontal direction and tiltable by a tilting mechanism to lower the extracted outer support end to the ground, said tilting mechanism comprising a pivot support supporting the telescopic beam at the vehicle body pivotable around a horizontal axis and a support drive comprising an telescopic drive element of variable length, with a first end of the drive element being pivotably attached to the vehicle body and its opposite second end being supported at the telescopic beam at a position between the pivot support and the support end of the telescopic beam. This jacking system is characterized in that the tilting mechanism further comprises a lever arrangement for load transmission between the support drive and the telescopic beam, said lever arrangement comprising a first lever with a first end pivotably attached to the vehicle body at a first hinge point below the attachment point of the first end of the drive element at the vehicle body, and a second lever with a first end pivotably attached to a second end of the first lever at a second hinge point and a second end pivotably attached to the telescopic beam.

1. Jacking system (10) for a utility vehicle, comprising a telescopic beam (14) suspended under the vehicle body (12) which is extractable in a generally horizontal direction and tiltable by a tilting mechanism to lower the extracted outer support end (20) to the ground, said tilting mechanism comprising:
a pivot support (24) supporting the telescopic beam (14) at the vehicle body 12) pivotable around a horizontal axis, and a support drive (26) comprising an telescopic drive element (28) of variable length, with a first end (30) of the drive element (28) being pivotably attached to the vehicle body (12) and its opposite second end (34) being supported at the telescopic beam (14) at a position between the pivot support (24) and the support end (20) of the telescopic beam (14),characterized in that the tilting mechanism further comprises a lever arrangement for load transmission between the support drive (26) and the telescopic beam (14), said lever arrangement comprising:
a first lever (36) with a first end (40) pivotably attached to the vehicle body (12) at a first hinge point (42) below the attachment point of the first end (30) of the drive element (28) at the vehicle body (12), and a second lever (38) with a first end (48) pivotably attached to a second end (44) of the first lever (36) at a second hinge point (46) and a second end (50) pivotably attached to the telescopic beam (14).
