Definitions

  • This invention relates to a rear suspension which is applicable to a vehicle which is tiltable for cornering.
  • vehicles are known in various constructions, notably as tricycles, for example, such as that disclosed in WO96 / 24681 Motorized Tricycle Vehicle.
  • the tricycle has a driven front wheel and two trailing rear wheels on spaced tracks continuously. The aim was to create a compact, narrow vehicle that can be used with minimal space on the road especially for commuter traffic, but still offers full weather protection.
  • tricycles are known which have a single rear wheel and front two wheels running on spaced tracks, such as the well-known Morgan Three-Wheeler and similar constructions.
  • a major advantage of a tricycle is that there are few building codes and standards that it needs to meet, so it can be relatively inexpensively developed and built and also easily gets a traffic permit. If a tricycle is designed with a narrow track, just to take up little space in the traffic flow and to be agile, it must be tilted for cornering, otherwise the vehicle would soon tip over.
  • a two-wheeler also has a slim silhouette, but first of all, two-wheel driving is not for everyone and it also requires a special two-wheel driver's license, and on the other hand you are exposed to the weather on a two-wheeler and have to set foot on the ground each time you stop not fall over.
  • the conventional tiltable three- and four-wheeled vehicles usually work with a complicated tilt system, which takes over the sensor-controlled active tilting of the vehicle for cornering.
  • this intervention in the driving dynamics is often perceived as disturbing.
  • the suspension is designed so that the vehicle is always freely tilted, then the stability is missing when stopping and the vehicle tilts to one side, if the tilt capability is not prevented or one puts a foot on the ground. But if you have to park one foot on the ground, the vehicle can not be realized with a really closed cabin for weather protection.
  • the object of the present invention is therefore to provide a rear suspension for a tiltable in the curve, rear two-lane vehicle, which provides a free tilting of the vehicle for cornering, but at very slow speed and standing up the two rear wheels in stabilizes the way that the vehicle - whether in a flat or in any direction inclined ground - consistently keeps upright in the Lot, so that the vehicle is stable and can stand up with a foot failure.
  • the vehicle should be able to be realized even with a closed cabin, although it is executable with a narrow track and therefore requires very little space on the street as well as on parking lots. It does not matter if this vehicle is designed as a three- or demorädriges vehicle, so with front only one wheel or two wheels with tiltable suspension. It does not matter how the vehicle is driven, whether with an electric motor, with a gasoline or diesel engine or with other sources of power.
  • a rear suspension for a tiltable in the curve vehicle with two about a transverse axis to the vehicle longitudinal axis up and down pivoting trailing arms, at the ends of the rear wheels of the vehicle are mounted, and which is characterized in that the trailing arm are directly or indirectly hingedly connected to the outer ends of a balance beam whose central pivot point is supported directly or indirectly by a strut on the chassis.
  • Figure 1 The vehicle with this rear suspension seen from the side, in an upright, vertical position;
  • Figure 3 The vehicle with this rear suspension from obliquely behind seen in the left-inclined position, as in cornering for a left turn;

  • Figure 7 The rear suspension in a view seen from the left side;
  • FIG. 8 The vehicle with a purely manually operable via foot pedals
  • FIG. 1 an overall concept of a vehicle with such a rear suspension is shown first. It is a three-wheeler with a single front wheel, which is like a motorcycle on a shock absorber suspension fork 21, down the rear two parallel running rear wheels 1 1, 12, but so hung, sprung and guided that the Total vehicle is tiltable in the curve.
  • the vehicle is equipped here with a single seat 27, especially as a suitability for commuter traffic.
  • a single person weighing on average about 80kg ⁇ 30kg of mass has to be transported from their place of residence to work and in the evening, and this should be done as comfortably, ecologically and economically as possible.
  • Comfortable means the vehicle should allow a weather-protected transport, with heating and / or cooling. This can be achieved in the present case, because the rear suspension to be disclosed makes it possible to realize this vehicle concept with a closed cabin, which is then readily heatable and / or coolable. Comfortable also means that the vehicle can be driven with normal clothing - by gentlemen if necessary in a fine business suit, by women also in Weg-Piece or Jupe or Rock, just as you can move with a closed car. Finally, comfort also means that listening to the radio and telephoning while driving is readily possible, and modern electronic devices can also be used for navigation and communication.
  • the vehicle is then when it is mobile with the least possible expenditure of energy.
  • it is equipped with electric motors which offer the highest efficiency of all drives for the conversion of energy into mechanical work.
  • With an electric drive the vehicle does not emit CO2 directly and is also quiet. Nevertheless, constructions with internal combustion engines or hybrid drives can also be implemented as required.
  • the vehicle is because it is designed to be particularly compact and especially narrow thanks to its special rear suspension, and while driving is still tilted for cornering, and because it has a small total mass and correspondingly little energy is needed to it to move.
  • it offers because of its construction as a tricycle the particular advantage that only a few building codes are to be met and therefore it is very easy and can be produced with relatively few components, and as a tricycle internationally with both the car driver's license or the motorcycle driver's license is mobile , Because of its simplicity and compactness, it is easy and inexpensive to produce and its operation is also due to its energy efficiency and its relatively low weight also inexpensive, which is why it qualifies as a highly economical vehicle.
  • FIG. 1 In FIG. 1, only the mobile chassis 24 with all components necessary for the driving operation is shown. It is clear that this chassis 24 can be equipped with a closed cabin, so that the whole driver area is weatherproof.

At this rearwardly extending and about the transverse bearing 17 on the chassis 24 up and down pivoting trailing arms 1 are at their rear ends of the rear wheels 1 1, 12 stored.

  • Under the seat 27th is the battery 18 and is an electronic control unit
  • the two trailing arms 1 are provided with an upwardly projecting pivot lever 2, which is supported by a strut 3 on the trailing arm 1.

  • Such tilt sensors are available today from bar. Installed on this vehicle, they measure its lateral inclination relative to the plumb when the vehicle is standing almost still or standing still. The deviation from the solder is determined directly and can be reduced by means of other facilities to be described, thanks to the special rear suspension immediately to a minimum. However, these actions are only necessary when approaching or completely resting the vehicle.

  • the shock absorber in turn includes a shock absorber 6, so that each rebound and rebound is attenuated.
  • This construction ensures that the suspension is effective, no matter what altitude the individual rear wheels 1 1, 12 are located. They are always coupled to each other via the balance beam 8 and move up and down alternately. If one rear wheel is pivoted upwards, the other is pivoted downwards and vice versa, depending on whether the load acting on the left or right rear wheel outweighs.

  • a problem with such a rear suspension with freely swinging rear wheels is basically the stopping and resting with the vehicle.
