International Classification:

B60R 3/00

US Classification:

280166000

Abstract:

A lift assembly for mounting a running board on a vehicle and operational to raise and lower the running board. The lift assembly includes a support structure configured for mounting to the vehicle, a slide assembly slidably supported by the support structure for movement in a longitudinal direction of the lift assembly, arm assemblies pivotably supported by the support structure, and a device for moving the slide assembly relative to the support structure. The slide assembly includes followers that cam with camming members of each arm assembly. Each arm assembly further includes a shaft for supporting the running board. Each shaft is located on its arm assembly so as to move downward and upward when the arm assemblies are pivoted relative to the support structure as a result of the followers of the slide assembly camming against the camming members of the arm assemblies.

Abstract:

A pump assembly comprises a hydraulic fluid pump having a housing assembled from a plurality of housing components that are pinned together rather than being clamped together by bolts. The pump is disposed in a cavity in a valve block so that the outlet fluid pressure from the pump is applied axially to the housing components to create a greater external axial force on the pump components than the internal axial force and thereby maintain the housing components in tight, sealing relation without the need for clamping bolts or other clamping means.
