The teachings of Suto
Suto's invention relates to vehicle toys and their suspension systems, particularly
the suspension of steerable road wheels. One object of Suto's invention was to provide
a vehicle toy with a wheel suspension system which can function independently
on either side of the vehicle toy, produce no or very little inclination of the wheel when
the vehicle toy moves up and down, and is fairly simple in construction.
As shown in Figures 1 and 6, the vehicle toy truck 30 is provided with an upper
body 32 forming a top side of the vehicle body and molded of plastics or the like, and a
lower body forming a chassis 34 supporting the upper body 32 disposed thereon, the
chassis 34 forming a bottom side of the vehicle body. Provided in the interior of the
vehicle toy are a printed circuit board having a receiver circuit for the radio control, and
a battery as an electric power source supplying an electric current to the receiver circuit
and a motor of the vehicle toy. A drive unit 38 is mounted at the rear of the chassis 34,
the drive unit 38 being provided with a drive motor and a transmission mechanism.
Right and left front steerable wheels 40b, 40a are connected to the front of the chassis
34 through a suspension system 42 which operates independently on opposite sides of
