Description

B62D covers the construction, design, and component technologies of motor vehicles and trailers. This subclass encompasses chassis design, steering systems, suspension mechanisms, braking systems, body structures, and coupling devices for vehicle attachment. It includes passenger cars, trucks, buses, and towed or semi-trailers, but excludes railway vehicles and rail-guided systems. Related design aspects covered here interact with engine technology (classified separately under B60) and manufacturing processes classified elsewhere.
