Definitions
- the invention relates to a two-wheeled transport vehicle, of the type comprising a carrying frame with a steerable front wheel, a steering with handlebars for controlling the orientation of the front wheel, a small diameter rear wheel carried by an arm. oscillating articulated on the frame, a seat fixed on the frame between the wheels and a loading support at the rear of the seat, located above the rear wheel.
- the invention relates more particularly, but not exclusively, to a motor vehicle, in particular a transport motorcycle.
- the object of the invention is, above all, to provide a transport vehicle with two wheels which allows a large loading volume while remaining of a relatively simple construction. It is further desirable that the driving of such a two-wheeled vehicle remains similar to that of a conventional motorcycle with handlebars and that the advantages of conventional motorcycles in terms of traffic and parking are preserved.
- a two-wheeled transport vehicle of the kind defined above, is characterized in that the driver's seat is located closer to the axis of the front wheel than to the axis of the rear wheel and that the loading support comprises a plate extending at least partially in front of the rear wheel; advantageously, the plane of the plate is arranged just above the zone of travel of the rear wheel and all the constituent elements of the vehicle, which are behind the vertical plane passing through the rear edge of the seat, are arranged below the plan of said plateau.
- the advanced position of the seat combined with the small diameter rear wheel, provides loading capacity important both in the direction of the length of the vehicle (advanced position of the seat and clearance under the seat) as in the direction of the height (low position of the platform due to the small diameter of the rear wheel).
- the steering handlebar is offset forward and rotatably mounted at the end of a console projecting forward, while transmission means are provided for communicating the rotation of the handlebar to the column of direction.
- These transmission means can include a deformable parallelogram mechanism.
- the front wheel has a diameter greater than that of the rear wheel (which makes it possible to preserve the gyroscopic effect as well as the stability and the braking qualities of a conventional motorcycle) and is supported by a fork mounted pivoting relatively to the frame.
- the rear wheel may have a diameter of the order of that of the scooter wheels, that is to say that the outside diameter of the tire of the wheel is between 38 and 52 cm approximately.
- the ratio of the outside diameter of the tire of the front wheel to the outside diameter of the tire of the rear wheel is between approximately 1.1 and 2, and better still between approximately 1.2 and 1.6.
- the outside diameter of the tire of a wheel is the maximum diameter of the tread of said wheel.
- the vehicle frame is advantageously constituted by a main beam, substantially L-shaped, the raised branch of the L being forward; this helps to increase the loading volume.
- the driver's seat is preferably fixed in the vicinity of the upper end of the rising front part of this master beam, which makes it possible to free up the space which it overhangs.
- the vehicle has an engine
- it is advantageously constituted by an oscillating engine group.
- the swinging arm carrying the rear wheel can then also support the motor.
- the swinging arm can be supported by a yoke, in particular in cast aluminum, fixed to the rear lower part of the vehicle's main beam.
- the engine block can be integrated into the swingarm.
- the swinging arm is formed by the assembly of a connecting plate, the front of which is articulated on the yoke and the rear is fixed to the engine block, and a rear plate, the front of which is fixed to the engine block and the rear of which is connected to the axis of the rear wheel.
- the entire arm has a substantially horizontal mean direction.
- the plate can have a length of between 0.8 and 1.6 m approximately; it can support a container, whose volume can reach up to 1 m 3 , or a cabin to constitute a motorcycle taxi, or any other desired adaptation.
- the volume of the container can communicate with that of a trunk formed below the tray, behind the rear wheel.
- FIG. 1 is a left view of a two-wheeled vehicle according to the invention.
- FIG. 2 is a partial right view of the rear of the vehicle, on a larger scale
- FIG. 3 shows, similarly to Figure 2, the rear of the vehicle seen from the right, partly in section and partly outside;
- - Figure 4 is a schematic longitudinal section of the front of the vehicle with part cut away;
- FIG. 5 is a top view of the tray at the rear of the vehicle
- FIG. 6 is a top view of the rear of the vehicle, the tray having been removed;
- FIG. 7 is a view of the rear of the vehicle
- FIG. 8 is a view of the rear of the frame alone, the engine, the rear wheel and the plate being removed;
- FIG. 9 is a partial view along the line -IX of Figure 2;
- FIG. 10 is a view of the handlebars and the following direction the arrow X in FIG. 1;
- FIG. 11 is a section along line XI-XI of Figure 10.
- a two-wheeled transport vehicle 1 of the motorcycle type comprising a steerable front wheel 2, a direction D with a handlebar 3 for controlling the orientation of the front wheel , and a rear wheel 4 of small diameter.
- the front wheel 2 corresponds to a normal motorcycle wheel, the outside diameter of the tire being approximately 58 cm while the rear wheel 4 has a diameter significantly smaller than that of the front wheel and corresponds to a scooter wheel, the diameter outside of the tire being approximately 43 cm.
- the diameter of the front wheel 2 is equal to 1.36 times the diameter of the rear wheel 4.
- the vehicle 1 comprises a support frame C, which comprises a master beam 5 in the form of L with a raised front part 5a and a substantially horizontal rear part 5b.
- the rear wheel 4 is supported by an oscillating arm B (fig. 3) whose mean direction is substantially horizontal.
- the arm B extends rearward from a hinge pin 6 mounted on a yoke 7 fixed to the lower rear part of the frame C.
- the yoke 7 has two ears 7a, 7b, spaced from one another, projecting rearward and crossed by coaxial bores serving as bearings for the axis 6.
- the engine block 8 is also supported by the arm B.
- the engine block 8 is integrated in the arm B.
- This arm B is then formed by the assembly of a junction plate 9 (FIG. 3), of the engine block 8 and of a rear plate 10.
- the plate 9 is articulated at the front on the pivot axis 6, and is fixed at the rear to the engine block 8.
- the rear plate 10 is fixed, in its front part, to the engine block 8; the axis X4 of the wheel 4 is supported on one side by the plate 10 and on the other by the casing of the transmission of the engine block 8.
- a combined "spring-shock absorber" 11 is arranged on one side of the engine block, for example on the right side, between an anchor point 10a provided in the upper part of the rear plate 10 and an anchor point 12 provided on a cross member 13 forming part of a frame 14 integral with the frame C.
- Clevis 7 is made of molded light metal, in particular cast aluminum. It is integral with the main beam 5 and has two lateral extensions 7d, 7g towards the rear as visible in FIG. 8. These extensions 7d, 7g serve as anchoring points for triangulation beams 15d, 15g, for example formed by hollow profiles with rectangular section, which support the side members 16d, 16g of the frame 14. At their front end the side members 16d, 16g are themselves fixed to the front cross member 17, itself fixed to an upper extension 7h of yoke 7, as shown in Figure 1.
- the rectangular shaped frame 14 has a front cross member 17 and a rear cross member 18 and, between the two, a central cross member 13. It is surmounted by a plate 19 made of wood or composite material, which covers the rear wheel 4 and constitutes a loading support S.
- a trunk 20 is provided at the rear of the frame 14, farther back than the wheel 4, and projects downward.
- the trunk 20 is closed by a hatch 21 disposed towards the rear of the tray 19 and articulated with respect to said tray by means of hinges 22 provided on the front side of the hatch 21.
- the seat 24 of the driver P is pushed forward; this seat is directly fixed to the rising part of the master beam 5 near the geometric axis of rotation A of the steering column G secured to a fork 25 carrying the front wheel 2.
- the base of the seat or saddle 24 is fixed at three points on a part 5ac constituting the upper end of the rising part 5a of which it is integral.
- the part 5ac is a molded part produced in a similar way to the yoke
- the steering column G is pivotally mounted in this part 5ac.
- the seat 24 is located closer to the axis X2 of the front wheel 2 than to the axis X4 of the rear wheel 4. This advanced position of the seat 24 makes it possible to place the front edge 19a of the plate 19 well in front of the 'axis X4 of the rear wheel, up to the vicinity of the vertical V passing through the rear edge of the seat 24.
- the handlebar 3 is rotatably mounted at the end of a console 26 projecting forward.
- the geometric axis of rotation ⁇ of the handlebar 3 intersects FIG. 10 at point 27.
- the axis ⁇ of rotation of the handlebar 3 is thus offset forward relative to the axis A of the steering column G; it is preferred that the axes A and ⁇ are parallel.
- Transmission means T are provided for communicating the rotational movement of the handlebar 3 to the steering column G and to the fork 25.
- These transmission means T comprise two parallel tie rods 28d, 28g articulated at their respective ends on the handlebar 3 and on a plate 29 (often called: fork T) integral with the fork and able to rotate about the axis A.
- a deformable parallelogram having the four points of articulation of the tie rods 28d, 28g is thus formed and allows the transmission the movement of rotation of the handlebar 3 to the fork 25.
- the handlebar 3 is mounted on a ball bearing 30 provided at the end of the console 26.
- the main beam 5 has a hollow section, for example rectangular, and its internal volume serves as a fuel tank 31.
- the tank cap 32 is provided on the upper face of the part 5a, just in front of the tip of the seat, and a fuel tap 33 is provided on the left side of the part 5ac.
- the length L of the plate can be of the order of 1.2 meters.
- the width W of the plate 19, as visible in FIG. 5 is less than the length L.
- a container 34 shown diagrammatically in FIG. 1 having a height of the order of a meter, in particular due to the very low position of the plate 19 behind the conductor; the width can also be of the order of 0.70 m, which makes it possible to have a container of approximately 0.85 m 3 .
- the volume of the trunk 20 can communicate with that delimited by the container 34 thanks to the opening of the hatch 21.
- a cabin can be installed to constitute a motorcycle taxi or any other desired adaptation.
- FIG. 6 a stand 35 in position noted.
- an exhaust with silencer 36 is arranged on the rear right side, the filter housing 37 being arranged on the left side; in FIG. 2, we see one of the two radiators 38 associated with the engine block 8 and in FIG. 3, we see the battery 39 inserted in a recess made in the yoke 7.
