A front wheel suspension for a motor vehicle including a vehicle frame having a pair of upper frames which are spaced transversely and extend longitudinally and a pair of lower frames which are spaced transversely and extend longitudinally, each of the upper frames having a downward portion extending from a front portion thereof and having a lower end fixed to one of the lower frames, front and rear wheels rotatably disposed on front and rear portions of the vehicle frame, a rider's saddle disposed on the upper frames, and footsteps supported on the lower frames. The front wheel suspension comprises a subframe adapted to be attached to the vehicle frame and having a pair of extensions adapted to be disposed upwardly of the lower frames, respectively, substantially parallel thereto, and a curved portion interconnecting the extensions, a pair of link mechanisms on which the front wheels are adapted to be supported, respectively, for vertical angular movement, the link mechanisms respectively including upper arms pivotally mounted on the respective extensions of the subframe, lower arms adapted to be pivotally mounted on the respective lower frames, and knuckle arms supported by the upper and lower arms, and a pair of dampers adapted to be mounted on the vehicle frame and supporting the link mechanisms, respectively.

Front wheel suspension for a motor vehicle with riding saddle

An engine breather device in a motor vehicle having a vehicle frame including longitudinal upper and lower frames, front and rear wheels rotatably supported on the vehicle frame, a handlebar mounted on the vehicle frame for steering the front wheels, a rider's saddle disposed on an upper portion of the vehicle frame, footsteps disposed on a lower portion of the vehicle frame. The engine breather device comprises a substantially vertical pipe frame adapted to interconnect the upper and lower frames and having at least one opening, an engine adapted to be mounted on the vehicle frame and having a crankcase and a cylinder projecting upwardly from the crankcase, the cylinder having a hole extending from the upper end thereof into the crankcase, and a breather tube providing communication between the interior of the vertical pipe frame and the interior of the crankcase through the hole in the cylinder, the breather tube being connected to the engine at a first position above the upper end of the cylinder and to the vertical pipe frame at a second position lower than the first position. Since the engine breather tube employs the existing vertical pipe frame, it is made up of a reduced number of parts and simple in construction. The breather tube prevents water from entering the engine therethrough even when the engine is substantially fully immersed in a deep puddle.
