Bearing body for motorcycle

DETAILED DESCRIPTION I claim: 1.
In a motorcycle: a support body having a longitudinal median plane; an oscillating arm fulcrummed to said body for pivoting movement about an axis transverse to said longitudinal median plane, said arm extending rearwardly of said pivot axis; an engine/transmission assembly carried by said arm at a location rearwardly of said pivot axis and laterally of said longitudinal median plane; a rear wheel drivingly connected to said engine/transmission assembly and located generally in said longitudinal median plane; an exhaust silencer carried by said engine/transmission assembly so as to oscillate therewith, said silencer being located generally in said longitudinal plane and forward of said rear wheel and at least partially forward of said pivot axis whereby the lateral space adjacent said rear wheel on the side thereof opposite said engine/transmission assembly is not encumbered by said silencer, said body having downwardly and inwardly facing walls forming a downwardly facing cavity in which said silencer at least partially resides and oscillates.
2.
A motorcycle as in claim 1 wherein said support body includes two lateral cowls on opposite sides of said body, one of said cowls at least partially housing said engine/transmission assembly and the other cowl at least partially housing a spare wheel which is releasably secured to said body.




Description:
The object of the present invention is a bearing body for motorcycles, such as motorscooters, which features constructional artifices of a kind that permit a useful arrangement of the exhaust pipe silencer.
The exhaust pipe silencer of a motorcycle is generally disposed on one side of the vehicle.
For example, motorscooters are known which have their rear drive wheel mounted in cantilever fashion on an oscillating arm which also bears the engine/transmission assembly disposed on one side of the vehicle, the exhaust pipe silencer being disposed on the opposite side of the vehicle.
With this arrangement, the exhaust pipe silencer is located laterally to the rear drive wheel and is free to oscillate
