Dennis Falcon - Design

Design

The Falcon was closely derived from the Dominator, the front half of the chassis being identical. The original horizontal-engined Falcon H had a layout recalling that of the Bristol RE with the longitudinally-mounted Gardner engine driving forward above the Dennis-built portal rear axle to a Voith gearbox and reversing unit which then took drive rearward into the driving-head of the axle. The later Falcon HC had a more orthodox continuous driveline, resembling that of the Seddon Pennine RU, the C (for continuous drive) denoted the Voith transmission close-coupled to the Gardner engine with a short propeller shaft taking drive into a straight Kirkstall spiral-bevel double-reduction rear axle. For these types the frame was raised aft of the rear axle to provide clearance for the under-slung engine.

The Falcon V, with Daimler-Benz V6 engines in the double decks and Perkins V8 engines in the coaches, was even closer in frame-concept to the Dominator.
