TITLE: Motorcycle Conversion Kit
FIELD OF THE INVENTION:
This invention relates to motorcycle conversion kits for adding
auxiliary wheels to motorcycles, and more particularly is concerned with
kits for converting motorcycles from two to four wheels. The kit being
easily installed and removed without major modification to the motorcycle.
BACKGROUND OF THE INVENTION:
Modern full sized touring motorcycles have become increasingly
heavy over the past years. This is in part due to the desire from the
consumer for larger, more powerful machines having larger displacement
engines but also as a result of the increasing number of luxury amenities
found on modern motorcycles which can include: navigation systems,
climate control systems, communication systems, entertainment systems
and expansive luggage compartments. With this added weight comes the
inevitable condition of motorcycles becoming top heavy and very
cumbersome at slower speeds.
The problem of slow speed stability is also encountered by
inexperienced motorcyclists who are prone to spills when they are learning
to ride.
This problem is solved in part by prior art conversion kits, the most
relevant is US Patent 5,853,057 to Mullins, which teaches a conversion kit
having a generally U-Shaped frame member to which are mounted two
auxiliary wheels. The frame member mounts to the motorcycle frame by a
pivotal connection at a front end and at a rear end the frame member is
rigidly connected to the motorcycle's swing arm. With such an
arrangement, the three rear wheels are forced to move in unison. This has
the disadvantage that if only one of the wheels encounters an obstacle,


CA 02404619 2004-05-20

3
such as a bump, while moving at speed, the other two wheels are urged to
move with the first wheel causing a potentially unstable and dangerous
condition which could lead to an accident. Also, when one attempts to
corner with a motorcycle equipped with the Mullins' kit, it is impossible to
tilt the motorcycle as one normally would to better negotiate the turn, which
leads to an awkward feeling for the rider.
Other motorcycle conversion kits known in the art are provided for
converting motorcycles into trikes or three wheeled machines. This
involves extensive modifications of the motorcycle which are sometimes
virtually irreversible. This solution is therefore not satisfactory.

SUMMARY OF THE INVENTION:
Therefore, the main object of the present invention is to provide a
motorcycle conversion kit wherein each of the rear wheels is independently
suspended in order to overcome the aforementioned drawbacks of the
prior art.
Accordingly, there is provided a motorcycle conversion kit
comprising a generally U-shaped frame member having parallel, spaced
apart side members having front and read ends, said side members are
angled towards each other near the front end thereof. Front and rear cross
members extend between the front and rear ends of the side members,
respectively. A rear wheel of the motorcycle being received in a space
between the side members. The frame member is rigidly attached to the
motorcycle frame via quick attachment brackets at the front and rear ends
thereof. An auxiliary wheel is mounted to each of the side members by a
trailing arm suspension member such that the rear wheel of the motorcycle
and each of the auxiliary wheels are in axial alignment and are
independently suspended.

Each trailing arm suspension member comprising an arm
member having a hole in each end. A pivot shaft extends from a proximal
hole in a first direction, perpendicular to the arm member and a wheel hub
extends from a distal hole in a second direction, perpendicular to the arm
member. The hubs are rotatably mounted on ball bearings and have a
plurality of studs for mounting the auxiliary wheels.
The trailing arm suspension member comprising a housing rigidly
mounted to the side member, the pivot shaft extending inside the housing,
and a compressive material, such a rubber, filling a space between the
housing and the shaft. Said compressive material being adhered to both
the housing and the shaft to resiliently restrain the shaft from rotation
within the housing.
The frame member further comprising adjustment means at the front
end to allow for proper alignment of the auxiliary wheels with respect to the
rear wheel of the motorcycle. The adjustment means comprising a tie-rod
having a threaded portion received in a forward most extremity of each of
the frame side members and a nut associated therewith to lock the tie-rods
in position once they are properly adjusted. The tie-rods also having an
eyelet at one end to receive a pair of mounting bolts therethrough.
The front quick attachment bracket comprising a tubular member
extending between the tie-rods. Said bracket further comprising a piece of
angle iron welded to the tubular member which extends parallel thereto.
The angle iron having a pair of holes at each end for receiving a pair of U-
bolts. The front quick attachment bracket is mounted to the motorcycle
frame directly beneath the motor by means of the U-bolts.
The pair of mounting bolts are used to secure the front end of the
frame member to the front quick attachment bracket. Each of the
mounting bolts extending through a tie-rod eyelet and into the tubular
member.


CA 02404619 2004-05-20

A pair of spaced apart lugs extend vertically from the rear cross
member. Each lug having a vertical slot therein to allow for vertical
adjustment of the rear end of the frame member.
The rear quick attachment brackets consisting of a pair of vertically
extending planar members. Each rear quick attachment bracket extending
between a rear portion of the motorcycle frame and a respective lug. Bolts
are used to secure the rear quick attachment brackets in place.
Another aspect of the present invention is to provide a trailer hitch
mounted to the rear cross member.
A further aspect of the present invention is to provide a fender
covering each wheel to protect the rider and other motorists for debris and
water which may be expelled from the rotating wheels. Each fender may
also have signal lights for improved visibility and security.
In an alternate embodiment, the lugs may be located on the frame
side members instead of on the rear cross member to suit a particular
application, such as smaller sized motorcycles.
Optionally, the motorcycle conversion kit may be provided with a
custom color scheme to match that of the motorcycle on which it will be
installed.
