Abstract

The invention relates to single-track vehicles which automatically stay in an upright position both when in a standing position and also during travel and are therefore suitable to be equipped with driver's cabs which protect their occupants in just the same manner as is expected from modern, multi-track cars. The single-track vehicles according to the invention require neither mechanical mechanisms nor mechanisms which are based on a gyroscopic effect for keeping their position upright, rather they maintain this position merely with the stable equilibrium. On account of their single-track arrangement, small vehicle width and other small dimensions, on the one hand, and their driver's cab and the driving comfort associated threwith, on the other hand, they are therefore adequate all-purpose vehicles and are in particular outstandingly suitable for town traffic.

Description

I. Known: Single-track vehicles, e.g. B. bicycles, scooters, Motorcycles etc. have to go through constantly while driving Changing the direction of travel must be balanced, otherwise they will tip around.

Single-lane vehicles not in motion must either suspended or by means of lateral support on the tipping be prevented.

Single-track vehicles can also be built in, rotating quickly Spinning tops are kept in an upright position; This is however, involves a relatively high level of construction and energy expenditure.

Single-track vehicles that stand upright when standing and driving So far, there is no position to hold itself.

II. The object of this invention is the construction of single-track vehicles to make it possible both in the state and during the Hold the ride automatically in an upright position always straighten up after a sideways inclination and neither mechanical nor gyro based Support or erection elements are required.

III. What is new about the single-track vehicles according to the invention described here is:
You don't have to jack it up or jack it up, hang it up or hang it up before or after a trip or otherwise prevent it from tipping over by means of lateral support; and they also do not require any erection elements based on the gyroscopic effect.
If you come to a closed rail barrier, a traffic light looking for "RED" or any other "STOP" point while driving with such a single-track vehicle according to the invention, as a driver you do not have to take your feet off the vehicle, around your legs Spread out sideways as supports, still use any mechanisms to prevent the vehicle from tipping over - the single-track vehicle according to the invention remains completely upright by itself, it does not tip over, and it also starts again from this position, just like a multi-track car, for example.

These properties of the single-track vehicle according to the invention also make it possible to give it a coup-like open or sedan-like closed driver's cabin;
for example a cabin with crumple zone, airbag, rollover and side protection, rainproof, air-conditioned, heatable.
A cabin that protects the occupant as if in a normally equipped, modern multi-lane road vehicle. These aforementioned properties of the single-track vehicle according to the invention result from the fact that, in contrast to the conventional single-track vehicle, which is based only on the law of unstable equilibrium and which therefore tilts alone and without balance and support measures, the inventive single-track vehicle both from the stable equilibrium acting in it Ride as well as standing continuously and by itself in an upright position and automatically erected again after leaning due to driving.

For this purpose, single-track vehicles according to the invention each have at least one spindle-shaped impeller with an oval, basket arch-like or elliptical axial section. This wheel will go on Text here briefly referred to as "spindle wheel".

Fig. 1 schematically shows as an example such an inventive single track:

  • in a) it is in the direction of travel from right to left below,
  • in b) from bottom left to top right.

The front wheel is a disc wheel, the rear wheel is a spindle wheel. Both wheels are only on the road with their respective ones AP contact points on a single, common lane FSP on.

For the sake of clarity, only the two wheels are shown in the sketch and the driver, but not other vehicle parts.  

Fig. 2 shows in a) and b), as a conventional single-track vehicle, which is held only from the unstable equilibrium in an upright position, whenever the center of gravity SP is not exactly perpendicular to the support point AP, that is, when it is not in the prior is not constantly balanced with special measures or while driving and is prevented from falling over.

Fig. 3 shows how acts stable equilibrium in the novel single track:

  • a) The upright position of the single-track vehicle according to the invention is based on the fact that the spindle wheel connected to it will always level off in an axially horizontal position due to its shape and due to gravity on a flat, horizontal surface.
    The center of gravity SP lies exactly vertically in the line of gravity SL above the support point AP, and there is balance. That this is a stable balance shows
  • b) If the single-track vehicle according to the invention, for. B. from one tilting force NK tilted to the right, the bearing point is shifted AP from AP ′ by dimension X to AP ′ ′; hikes at the same time the center of gravity SP from SP ′ by the dimension Y to SP ′ ′.

The line of gravity SL and with it the SP '' are now by the measure X-Y to the left of the support point AP '', and at the same time was as a result the inclination to the right also the center of gravity SP ′ to the top right the dimension Z raised to SP ''.

This is from the gravity line to the left of the point of contact AP '' and resulting from the increase in the center of gravity from SP 'to SP' ' Restoring forces together cause the righting force AK, which, when the tilting force NK decreases, the spindle wheel axis (and the vehicle connected to it constructively) in the horizontal position and in stable equilibrium commutes.

Single-track vehicles according to the invention are based on this principle again and again automatically after lateral inclinations.

Fig. 4 schematically shows a single-seat single-track vehicle according to the invention; the vehicle has fork steering, the control head STK is arranged vertically above the support point APv of the front wheel; APv and APh lie in one direction on the common lane FSP. The center of gravity is in in.

Of the very different and diverse possibilities regarding Structure, drive type and intended use show the following figures some examples:

Fig. 5: The spindle wheel is driven by an internal combustion engine via two friction rollers.

Motor, friction rollers and spindle wheel together with an im Suspension pivot FDRP mounted rear swing arm one unit. The steering is designed as fork steering, the control head STK of the chassis is more forward than the front support point APv, which makes for a when turning the steering the driving behavior results in advantageous caster NL (in contrast in addition - in certain cases - a lead VL can also be achieved become). The center of gravity is in in.

Fig. 6: The spindle wheel is flattened on the hubs and is equipped on the left side with a chain sprocket and on the right side with a brake disc. The rear swing arm has its axis of rotation FDRP axially identical to the drive pinion on the engine block. The vehicle has wheel steering, the center of gravity is again ⚫.

Fig. 7: The spindle wheel is a "multi-part spindle wheel" as shown in Fig. 15 and has two radial gaps. The two spars of the rear swing arm protrude into this column, which has its suspension pivot point FDRP axially identical to the chain sprocket on the engine block in the vehicle. Furthermore, the chain sprocket and (right) the brake disc of the spindle wheel are in the columns (left). The radially outer zones of the spindle wheel column are chamfered so that the columns widen outwards; Objects that get caught in the column while driving are released again by the rotating wheel. The vehicle is steered using a fork; the focus = ⚫.

Fig. 8: Here the vehicle is driven hydrostatically by means of oil pressure (left side with oil pressure hub motor in the spindle wheel and pump in the vehicle frame, A) or, as shown at B, by means of a cardan shaft.

The vehicle is steered using a fork; the center of gravity lies in ⚫.  

Fig. 9: Single-track vehicles according to the invention can also be equipped with a multi-wheel drive, for which the electric drive is particularly suitable (see also FIG. 13).

Here, a vehicle with friction roller drive is shown in FIG. 9 both on the front wheel and on the rear wheel. The steering is done with a fork. The center of gravity is in in.

For example, only elasticity is used for vehicle suspension of front wheel and spindle wheel tires.

Fig. 10: The driving properties of a single-track vehicle according to the invention are all the better the lower the overall center of gravity ⚫. Therefore, all heavy parts such as the chassis, engine, transmission, fuel tank, battery etc. as well as the intended seating position (s) of the driver (s) are accommodated as deeply as possible and in the hatched part of the sketch.

Superstructures for bodywork and facilities of all kinds are in the space outlined in dashed lines and are as easy as possible hold.

To prevent the vehicle from swinging back and forth during repairs, To prevent wheel changes etc. or for longer parking times, vehicles according to the invention can also be exhibited Parking supports can be equipped (PST).

Fig. 11: Here, a fast, sporty single-track vehicle of the type according to the invention is shown.

The spindle wheel is driven by a boxer motor via cardan, whose shaft in one of the two swinging legs of the rear wheel Swing arm runs. The front wheel, also swing-guided, has caster and is steered using normal motorcycle handlebars. The single-seat driver's cab has rollover and side protection, is hinged through two doors on the left and right of the vehicle are and in each case on the upper part of the relevant cabin roof part made of plexiglass, open or close. The cabin can be air-conditioned and heated.

Fig. 12 shows a two-seater vehicle according to the invention as a small sedan with a motorcycle-like seat arrangement. A motorcycle handlebar with two parallel rods leading to the steering head are used for steering. Rollover and side protection are provided.

The drive takes place here by means of a chain in a spar Encapsulated rear swing arm runs and its engine-side pinion driven by an in-line engine transverse to the direction of travel becomes. Of course, the cabin can be air-conditioned and heated become.

Fig. 13: Vehicles according to the invention can, for. B. in the municipal area (for parking and gardening, cemetery service, street cleaning, garbage disposal, etc.), in industrial and commercial areas, in forestry and agriculture and in winegrowing due to their single track and narrow vehicle width.

They are suitable here both as single vehicles and as towing vehicles in front of single or multi-car transport trains as well single-track vehicles.

Such multi-car transport trains can each consist of one preloaded towing vehicle and attached to it by means of ball-jointed towbars attached tow vehicles exist.

But you can also consist of single-track vehicles, each with its own motor-driven spindle wheel are equipped, which drives its energy via cable connection from the control and generator placed at the head of the transport train Vehicle relates.

Especially in difficult, swampy, loamy or icy terrain have such multi-wheel drive transport trains, they are in the true sense of the word, no longer "trains", but rather each time independent, multi-unit "single-track vehicle", large Advantages compared to conventional multi-lane vehicles.

This is where a fundamental property of the spindle wheel wins in importance:

The softer the surface on which a spindle wheel moves, the larger it becomes due to the rapidly increasing contact area the traction forces exerted by such a spindle wheel can.

Single-track vehicles according to the invention can also be used as train and / or push vehicles in connection with multi-lane vehicles be used.  

Spindle wheels can be constructed very differently. Here are a few examples:

Fig. 14: The "one-piece spindle wheel" is in principle an ellipsoid-like body with an oval, basket arch-like or elliptical axial section rotating about a fixed or only an ideal axis. This axial section is divided into the four quadrants I / II / III / IV; each part represents a constructive possibility.

I = One-piece spindle wheel with fixed axle, with tubular tires:
STA = thru axle;
AR = axle tube;
NKMA = hub head with axle;
KR = chain sprocket (or BRS = brake disc);
KKK = Cardan bevel gear clutch;
KA = carcass;
FKA = rim-like carcass reinforcement;
LDK I = running surface coupling; the total tread here consists of the two "outer treads" and the "inner tread" ÄuLD and InLD;
LFP = tread pattern;
SCHL = air hose.

II = one-piece spindle wheel with fixed axle, tubeless:
Like I, but without a hose, but with
LDK II = running surface coupling for II;
Dil = sealing lips.

III = one-piece spindle wheel without fixed axle, with tubular tires:
As before, but with
NKOA = hub head without axle.

IV = one-piece spindle wheel without fixed axle, tubeless:
Therefore with
Dil = sealing lips;
NKOA = hub head without axle.

Fig. 15: The "multi-part spindle wheel".

A) Its ellipsoid-like body is composed of two or more spindle wheel parts pushed together on a common axis, which are separated from one another by one or more radial gaps RASP. Through these radial gaps, the axle bearing and driving components reach into the spindle wheel (see also Fig. 7!).

B) As an example of this, the part in the drawing is in detail shown, which is delimited by dashed lines in A); he belongs to a "three-part spindle wheel" in this case, which consists of the two dome-like outer parts and the barrel-like in between Center piece is composed. In the process The resulting two radial gaps RASP protrude from the support spars TRH Rear swing arm. You can see:

STA = thru axle;
AR = axle tube;
NKK = hub cap; NKO = hub head;
KR = chain sprocket (the brake disc is on the right side);
KA = carcass;
FKA = rim-like carcass reinforcement;
LFP = tread pattern;
Dil = sealing lips (the spindle wheel parts are tubeless);
RASP = wheel gap with outside bevelled gap flanks;
TRH = support beam parts;
RLAG = wheel bearing.

The radially outer flank zones of the spindle wheel column are beveled towards the outside in an opening sense, so solid objects that get stuck while driving due to centrifugal force can solve again.

The STA thru axle is used only in this embodiment axial contraction of the three pushed onto the axle tube AR Spindle wheel parts that are interconnected by Rudge gearing or Claw coupling are non-positively connected.

The NKK hub cap closes the axle opening flush, so that the entire spindle wheel body also in the axis area has a harmoniously rounded shape.  

In the examples shown in Fig. 14 and Fig. 15 examples is inflated, pneumatic spindle wheels.

Spindle wheels can also be displayed in other ways, for example as
"multi-disc spindle wheel".

Fig. 16 shows the left half of a composite of a plurality of individual, each with different radii and with normal tires equipped spoked wheels vielscheibigen spindle wheel.

Fig. 17: The spindle wheel here consists of a large number of radially different individual wheels in the running surface, each adapted to the shape of the spindle wheel, each consisting of a hub, disk and rim, and a corresponding spindle wheel cap.

FIG. 18 largely corresponds to FIG. 17, but here the individual wheel disks consist of simple, frustoconical disks which are matched in the outer region of the spindle wheel shape and each of the same material.

Fig. 19: The core of the spindle wheel here is a cylindrical body with axially increasing radii, which can be hollow or solid or made of foam and are pushed onto the disc-like parts which, together with two corresponding hub caps, form the "multi-disc spindle wheel" .

Fig. 20: Many thin disks with different radii are pushed onto an axle tube, which together form the spindle wheel core and over which a layer forming the spindle wheel running surface and cap is placed.

Fig. 21: The spindle wheel here consists of a large number of individual disks, which are made of different materials of different elasticity and strength, so that the entire spindle wheel is a resilient, elastic body with an abrasion-resistant running surface.
