Low profile chassis and suspension
First Claim
1. An apparatus for a vehicle, comprising:
- a first rear wheel having a first rotational axis;
a second rear wheel having a second rotational axis;
a frame having a planar portion with a top surface and a bottom surface, said frame interconnecting said first and second rear wheels, said planar portion being located between said first and second rear wheels, the first and second rotational axes being located above the top surface, said frame including first and second frame members extending longitudinally across said frame and being located between said first wheel and said second wheels; and
an exhaust pipe supported by said frame and extending longitudinally along said frame below the top surface of the planar portion between said first and second wheels and above the bottom surface of the planar portion between said first and second wheels and between said first and second frame members.

Abstract
A low profile chassis and suspension system for a road vehicle. The chassis supports a payload section or cargo compartment, such as for a delivery truck, ambulance, or shuttle bus. The chassis includes a largely planar frame having a top surface which is located beneath the rotational axes of the rear wheels. The wheel suspension system is particularly compact and close to the road surface. A trailing arm-type wheel support supports a stub axle in a cantilevered fashion. A spring urges the wheel support apart from the frame. A planar portion of the wheel support, the wheel support pivot joints, and the spring are located beneath the rotational axis of the wheel. In another embodiment, the frame includes a recessed pocket which facilitates use of ramp for wheel chair access.

19. A vehicle, comprising:
-
a pair of driven front wheels; a front axle providing power to said front wheels, said front axle having a rotational axis; an engine and transmission for providing power to said front wheels, said engine having a rotational centerline that is approximately perpendicular to the rotational axis of said front axle, said transmission being located between said front axle and said engine; a rear frame with a substantially planar top surface; and a pair of rear wheels coupled to said rear frame, each said rear wheel having a rotational axis located above the planar top surface. - View Dependent Claims (20, 21, 22)
