SLIDABLE CURRENT COLLECTOR AND METHOD FOR CONTACTING CONDUCTOR RAIL
A slidable current collector has an array of terminals with carbon brushes for contacting conductor rails to deliver electrical power to a moving work machine. The terminals have upper sections with a conductive post, lower sections that include a reservoir of liquid metal, and bladders that connect the upper sections with the lower sections. Magnets surround outer shells of the terminals. Fluid above a threshold pressure fed into the bladders holds the upper sections apart from the lower sections and forces the magnets away from the conductor rails. Fluid below the threshold pressure allows the magnets to clamp the terminals to the conductor, lowers the conductive post into the liquid metal, and urges the carbon brushes against the conductor rails. The bladders provide a fluid suspension distributed across the array of terminals, enabling consistent electrical contact and wear for the carbon brushes.
An electromechanical joint provides rotational movement in at least two dimensions while conducting electrical power between orthogonal hubs. The joint, shaped as a cross, has four conical shafts positioned orthogonally and apart from each other within an interior of a housing. Apexes of the conical shafts face each other proximate a centroid of the housing. A conductive fluid, such as Galinstan, fills recesses between the conical shafts. Separate yokes attached to pairs of the hubs may impart forces on the shafts, causing the shafts to rotate within the conductive fluid around orthogonal axes. The conductive fluid provides simultaneous conduction of electrical power between the hubs. The yokes may be affixed respectively to a current collector and conductive arms of a work machine for improved movement and power conduction without the need for additional components.
A slidable current collector (118) has frame (302) formed as central substrate (308) and sloped shoulders (310, 312) on opposing lateral sides of the central substrate (308). Electrical terminals (306) pass through orifices arranged in at least two rows within the central substrate (308). At least one bumper (318) is disposed on an underside (324) of the central substrate (308) between the at least two rows.

If disengagement of the electrical terminals (306) from the rail surface (408) occurs, angles on the sloped shoulders (310, 312) and the at least one bumper (318) resist excessive lateral shifting and urge the electrical contacts to reengage with the rail surface (408).

Separate yokes (332, 334) attached to pairs of the hubs may impart forces on the shafts, causing the shafts to rotate within the conductive fluid (604) around orthogonal axes.

Electrical terminals pass through orifices arranged in at least two rows within the central substrate. At least one bumper is disposed on an underside of the central substrate between the at least two rows. During sliding on a power rail, the electrical terminals contact a rail surface, and the current collector can shift laterally on the rail surface across a distance between the bumper and one of the sloped shoulders.

Couplers on adjacent barriers (204-1, 204-0) can be mated together concentrically along a central axis. The mated couplers help restrict longitudinal displacement, lateral displacement, slope change, and lateral rotation between adjacent barriers during placement. One barrier may be used as a temporary alignment structure (204?0) to position barriers spaced alternatingly along a haul route (101) for the work machine (100).

A modular structure supports elevated rail segments (240) for delivering electrical power to a moving work machine (100), such as a hauler at a mining site. End portions (1106, 1108) of rail segments having narrower widths than body portions of the rail segments (240) are joined within a split fishplate (1102).

A brake controller of a machine can be configured to determine brake power associated with braking operations, such as operations to slow the machine or maintain a speed of the machine. The brake controller can allocate the brake power among systems such as a battery system, a resistive grid, auxiliary systems, a mechanical brake system, and/or other systems, based on a defined priority order of the systems. For example, the brake controller can prioritize using a regenerative brake system to charge a battery system during a braking operation up to a currently-available capacity of the battery system, and allocating any remaining brake power to a lower-priority system. The mechanical brake system can be the lowest-priority system, such that use of the mechanical brake system can be avoided unless an amount of brake power exceeds capacities of higher-priority systems to consume the brake power.
