Abstract
A vehicle having a chassis and a rotatable upper works is provided with a cylindrical electrical connector mounted remote from the axis of rotation of the upper works, to provide adequate ground clearance.
Claims12
A vehicle comprising:
- (a) a chassis, an upper works, means mounting the upper works for rotation on the chassis about a vertical axis, and means for rotating said upper works,
- (b) cylindrical electrical connector means for tranferring electrical energy between a fixed element and a rotary element and including a fixed part, a rotary part, and axially spaced conductor bands and contacts on said parts,
- (c) means mounting said connector means on said chassis remote from the axis of rotation of the upper works,
- (d) means for rotating said rotary part of said connector means from said upper works,
- (e) flexible electrical conductors extending through a hollow shaft and connected to said connector means and to electrical means on said upper works.
