A turbocharger comprising two closely spaced ball bearings that does not require lubricating oil from an engine. The bearing housing forms a cooling jacket with two bearing engagement surfaces engaged with the outer races of the ball bearings through an intermediate radial spring. Closely spacing the ball bearings provides a rotor shaft of minimal length. In addition, an external motor-generator may be by mounted on the turbocharger, with the motor rotor solidly connected to the turbocharger rotor. In such an assembly, an electronic control is energizes the motor from battery power during acceleration up to approximately torque peak speed; thereafter, the control changes to a generator mode when there is excess energy in the engine exhaust gas.

A telescoping push arm is included which actuates the barrier by means of a pivoted link which rotates the barrier in response to the telescoping motion of the push arm. A safety interlock and load detecting system may be employed to prevent the platform from moving to the stowed position when a load greater than a predetermined weight is on the platform. An anti-free fall mechanism is disclosed comprising a pin in the slide block which engages mating slots in the telescoping push arm members to lock their length during the initial stage of deploy of the platform downwardly from the vertical stowed position.
