Definition of subframe in US English:



  • A supporting frame, especially one into which a window or door is set, or one to which the engine or suspension of a car without a true chassis is attached.

    • ‘It is a one-piece cast-aluminum liftgate whose vertical casting process can be adapted to the production of door frames, firewalls, engine subframes, vehicle pillars, shock towers, and floor frames.’
    • ‘Specific features such as the front and rear chassis subframes are also consistent with the 626% general layout, though there are no hand-me-down panels or parts.’
    • ‘The front subframe uses hydroformed components for lightweight strength; the subframe is attached to the body with rubber floating mounts to minimize noise and vibration.’
    • ‘The upholstery was ‘a chassis’, that is, fixed to its own subframes independent of the main chair frame.’
    • ‘The rear suspension uses an aluminum subframe, axle housing, A-arm, and lower link.’
    • ‘The monocoque tub is a combination of carbon fiber and aluminum honeycomb with aluminum crush structures and chrome-moly subframes.’
    • ‘There is a new subframe to reduce cabin deformation in a collision.’
    • ‘Later, the team discovered that the incident had bent the front subframe of the car.’
    • ‘The chassis subsystems - front subframe, side rings, etc. - are built up by hand, with each piece fitted into jigs that use holes stamped in the parts as locating points.’
    • ‘This architecture spans the gap from unitized structures with front and rear subframes to vehicles like the Nissan Pathfinder that have frame sections welded to a unit body for increased strength.’
    • ‘Not rock hard, just sportingly firm, with that firm feeling no doubt amplified by the solidly mounted subframes.’
    • ‘The engine brackets, oil-pan and bonnet were all handcrafted to fit the new engine's contours and there were other modifications required to the subframe and other items.’
    • ‘The front subframe gets a cross-strut, the rear axle beam has been stiffened and dampers and springs now have separate mounting points.’
    • ‘The company is also developing a system which uses information from four deformation sensors installed in the seat subframe to perform absolute weight detection.’
    • ‘This new bonnet type will be built on a separate subframe.’
    • ‘Unlike the Jetta on which it's based, the new subframe is one piece instead of three, uses more aluminum, and has upgraded bearings for greater road isolation.’
    • ‘The front springs have been stiffened by 10 per cent, the diameter of the front anti-roll bar has been increased, the front subframe strengthened considerably, and the damper settings have been altered to suit.’
    • ‘The fuel tank and exhaust pipe routing were modified slightly to accommodate the new subframe.’
    • ‘Everything but the coil springs and dampers are mounted directly to a steel subframe that attaches to the body via four large rubber mounts.’
    • ‘Driving feel gets a dramatic improvement by relocating the steering rack to the front subframe rather than the body shell.’
