Description

Technical Field

[0001] The invention relates to a tilting vehicle with a bracket device. Background Art

[0002] Tilting vehicles, such as motorcycles or scooters, usually have very limited storage space. Therefore, additional luggage containers are often installed on the vehicle, such as side boxes installed on the sides in the rear wheel area.

[0003] So-called "top cases" are also known, which are mounted on a retaining bridge (also called luggage rack) in the rear region of a tilting vehicle. Since the top case may have a high weight in the loaded state and thus high static and dynamic forces or moments act on the retaining bridge, the retaining bridge is usually solid and made of metal. Usually, the retaining bridge is designed as a steel tube rod or an aluminum die-cast component.

[0004] In particular, the rear fastening point of the retaining bridge is subject to particularly high moment loads during vehicle operation. Therefore, the fastening point is usually designed as a very stable, rigid fastening of the retaining bridge on the rear of the tilting vehicle, which, however, also has a negative impact on the weight of the entire vehicle and the position of the vehicle's center of gravity due to the high component weight associated with this. Summary of the invention

[0005] The object of the present invention is to further develop a fastening device for a luggage container on a tilting vehicle, in particular to reduce its weight as much as possible.

[0006] This task is solved by a tilting vehicle.

[0007] Therefore, a tilting vehicle is provided, which has a rear section and a support device connected to the rear section, wherein the support device comprises a receiving section for releasably fixing a luggage container and is connected to the rear section in the region of the receiving section by at least one first support and is connected to the rear section by at least one second support arranged at a distance from the at least one first support. In addition, the at least one first support is designed so that it does not transmit torque.

[0008] In the context of the present description, tilting vehicles are understood to be, in particular, motorcycles or motorcycle-like motor vehicles, such as scooters, in particular tilting two-, three- or four-wheeled scooters, scooters or the like, as well as snowmobiles or quadricycles.

[0009] Therefore, tilting vehicles have a support device in the rear region, which is also called a holding bridge or luggage rack and is provided as a support for a luggage container. The luggage container can be connected to the receiving section of the support device if necessary or can be released again to remove it. For example, the receiving section can form a plane that exposes the luggage container from above, so that the receiving section supports the luggage container, for example from the underside of the luggage container.

[0010] The support device is connected to the rear section of the tilting vehicle via the at least one first support and the at least one second support and is thus fixed to the vehicle. The rear section is understood to be a section of the vehicle that forms the rear of the tilting vehicle and can be designed as a separate component, such as a rear frame, or as a (partial) section of a vehicle structure, such as a (partial) section of a vehicle frame and / or a (load-bearing or non-load-bearing) vehicle body.

[0011] It is understood that more than one first or second support may be provided in each case, but for simplicity's sake, reference is always made below to one first or one second support, which may represent one or more corresponding supports in each case, unless this is explicitly indicated otherwise.

[0012] According to a preferred embodiment, the support device is connected to the rear section by means of two first supports and two second supports. Preferably, the two first supports are arranged mirror-symmetrically with respect to the vehicle center oriented in the longitudinal direction of the vehicle. The same applies to the two second supports, which can also be arranged mirror-symmetrically with respect to the vehicle center.

[0013] In any case, the at least one first mount is configured such that it does not transmit torque. This means that the at least one first mount has at least one (or more) rotational degree of freedom and thus allows a rotational or tilting movement of the support device, but can still absorb forces at least in the height direction of the tilting vehicle. Preferably, the rotation axis of the rotational movement is oriented (e.g. horizontally) in the vehicle width direction.

[0014] This makes it possible that moments caused, for example, by a vertical movement of the luggage container can lead to a rotational movement of the support device in the region of the at least one first support. This can occur in particular if the center of gravity of the luggage container is located at a distance from the one or more first supports, in particular if the center of gravity is arranged behind the at least one first support in the longitudinal direction L of the vehicle.

[0015] For example, a rotational movement of the support device in the region of the first support can lead to a corresponding elastic deformation of the support device along its length, as a result of which the at least one second support is loaded at least in tension.

[0016] In any case, moment loading of the first support is prevented by the structural design, so that the first support can be designed to be correspondingly light. Instead of a generally very stiff and rigid design of the first support for compensating the moment, the moment is compensated according to the invention by means of a second support which provides a reaction force acting at a distance from the first support. Due to the lever length of the action, a heavy, in particular (torque) rigid design can also be dispensed with for the at least one second support.

[0017] In contrast, the support device can have sufficient bending stiffness. However, the bending stiffness can also be achieved by means of lightweight construction and lightweight materials, such as light metals or plastics including fiber-reinforced plastics. In addition to the obvious weight advantage over conventional, rigid and solid embodiments of the support device, this also offers the advantage that the design freedom in terms of dimensioning and shaping is significantly expanded.

[0018] For example, the at least one first support can be designed as a fixed bearing, in particular as a ball joint (also called a ball bearing) or a cylindrical joint (including a rolling joint). Fixed bearings are so-called two-value bearings, which can transmit two bearing reaction forces. Accordingly, a movement of the bearing is not possible, but torque cannot be absorbed and a rotation is allowed instead.

[0019] Alternatively or in addition thereto, the at least one first support may comprise an elastic connection element for disengaging the movement of the support device relative to the tail section. This means that the first support only comprises an elastic connection element and does not comprise a fixed support. In this case, the elastic connection element may be, for example, a rubber element, which also does not absorb torque and instead allows rotation. According to the structural design, the rubber element may additionally achieve a limited (lateral) movability within its elastic range.

[0020] However, the elastic connecting element can also be combined with a fixed bearing.

[0021] According to one embodiment, the at least one second support can be designed as a rigid connection as described above. The moment load is compensated, for example, by a deformation of the support device, so that the second support bears the tensile load. In addition, the rigid design can prevent undesired movement of the support device. Alternatively, the at least one second support can be designed as a fixed support.

[0022] For example, the distance between the second support and the first support can have a value between 5 cm and 100 cm, preferably between 5 cm and 40 cm.

[0023] Furthermore, the luggage container can be a box, in particular a top box, or a bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The invention is explained in more detail below on the basis of an exemplary embodiment in comparison with the prior art with reference to the drawings.

[0025] In the attached picture:

[0026] FIG1 shows a side view of the rear region of a tilting vehicle according to the prior art; and

[0027] Figure 2 A side view of the rear region of a tilting vehicle according to the present description is shown. DETAILED DESCRIPTION

[0028] 1 shows a side view of the rear region 10 of a tilting vehicle 1 (not shown) according to the prior art. The tilting vehicle 1 has a rear section 11 and a support device 12 connected to the rear section 11. The support device 12 comprises a receiving section 13 for releasably fixing a luggage container 14 and is connected to the rear section 11 in the region of the receiving section 13 by means of two first supports 15 and is connected to the rear section 11 by means of two second supports 16 arranged at a distance from the first supports 15. The two first supports 15 are each designed as a rigid support 15.

[0029] The luggage container 14 is, for example, a so-called roof box, wherein the center of gravity S of the luggage container 14 (in the longitudinal direction L of the vehicle) is arranged far behind the two first supports 15. This results in loads and moments caused by the gravity G having to be absorbed by the two rigid first supports 15. This results in a high load on the two first supports 15, so that they have to be dimensioned accordingly, which has a negative impact on the vehicle weight.

[0030] Due to the eccentrically acting weight G of the luggage container 14, the two first supports 15 are not only subjected to pressure but also have to absorb a moment at this location caused by the weight G. Correspondingly, in the case of negative acceleration, a tensile force acts on the two first supports 15 and an oppositely directed moment acts.

[0031] In contrast, the second support 16 is not loaded in the ideal case. However, since the support device 12 cannot be considered to be ideally rigid, it is extended by the tensile forces transmitted by it or shortened by the thrust forces. However, due to the movement, the support 16 can only partially cooperate in absorbing the moment, so that the majority of the moment is absorbed in the support 15.

[0032] Figure 2A side view of the rear region 20 of a tilting vehicle 2 (not shown in further detail) according to the present description, for example a motorcycle or a motor vehicle similar to a motorcycle, is shown. The tilting vehicle 2 thus has in the rear region 20 a rear section 21 and a support device 22 (also referred to as a retaining bridge) connected to the rear section 21, wherein the support device 22 comprises a receiving section 23 for releasably fixing a luggage container 24 and is connected to the rear section 21 in the region of the receiving section 23 by means of two first mounts 25 and to the rear section 20 by means of two second mounts 26 arranged at a distance from the first mounts 25. Furthermore, the two first mounts 25 are designed such that they do not transmit torque.

[0033] The luggage container 24 is detachably placed on the receiving section 23 from above, so that the luggage container 24 is supported on its underside by the receiving section 23 . The center of gravity S of the luggage container 24 (in the longitudinal direction L of the vehicle) is arranged behind the two first supports 25 .

[0034] The support device 22 is connected to the rear section 21 of the tilting vehicle 2 via the two first supports 25 and the two second supports 26. It is understood that more or less than two first supports 25 or two second supports 26 can be provided.

[0035] The two first supports 25 are arranged in the vehicle center, oriented mirror-symmetrically with respect to the vehicle longitudinal direction L, so that in the side view shown, only the first support 25 located in the front left is visible, wherein the second support is covered behind it. The same applies to the two second supports 26, which are arranged mirror-symmetrically with respect to the vehicle center, wherein in the side view, only the left second support 26 is visible, while the right second support located behind it is covered.

[0036] The two first supports 25 are designed such that they do not transmit torque. Therefore, in the event of a vertical movement of the luggage container 24, due to the fact that its center of gravity S is arranged behind the first supports 25 (in the longitudinal direction L of the vehicle), a moment M1 is caused in the region of the two first supports 25, which leads to an identically directed rotational movement or tilting movement of the support device 22 in the region of the first supports 25, which can be realized by the rotational degree of freedom of the two first supports 25.

[0037] Since the support device 22 is fixed in the two second supports 26, the moment M1 causes a corresponding elastic deformation of the support device along its length and loads the second supports 26 with a tensile force F2. The second supports 26 are designed to be rigid for this purpose, for example. The great advantage of this embodiment is that high moment loads of the two first supports 25 are effectively prevented and they can be designed to be correspondingly light.

[0038] Therefore, instead of the usually very stiff and rigid design of the first bearing 25 for compensating moment loads, according to the invention, the moment M1 is compensated by the two second bearings 26, which are arranged at a distance a from the two first bearings 25. Due to the lever length of the support device 22 acting at the distance a, a heavier, particularly (torsionally) rigid design can also be omitted for the two second bearings 26.

[0039] In contrast, the support device 22 can have sufficient flexural rigidity, which can likewise be achieved by means of a lightweight construction.

[0040] According to Figure 2 In the embodiment shown in , the two first supports 25 are each designed as a so-called fixed bearing in the form of a ball joint (also called a ball bearing). Correspondingly, a movement of the two first supports 25 is not possible, but no torque is absorbed and instead the described rotational movement of the support device 22 is allowed. Of course, the fixed bearing can also be designed in other ways, for example as a cylindrical joint (including a rolling joint). Alternatively or in addition to this, the two first supports 25 can also be implemented as elastic connecting elements in order to decouple the movement of the support device 22 relative to the tail section 21.

[0041] For example, the distance a between the second support 26 and the first support 25 can have a value between 5 cm and 100 cm, preferably between 5 cm and 40 cm.

[0042] Furthermore, the luggage container 24 can be a box, in particular a top box or a bag.
