Description

Exercise aid for a motor vehicle and motor vehicle

The invention relates to a driving exercise aid for a motor vehicle, such as a motorcycle or a passenger car, which can roll on a stationary reference surface of the inside of a hollow sphere construction, such as the so-called "Globe of Death." For this purpose, the motor vehicle comprises a chassis with at least two wheels , preferably three or four wheels.

An exercise aid to be attached to the motor vehicle is intended in particular to support stuntmen when training certain driving figures and, under certain circumstances, to protect against injuries in the case of accidents or unsuccessful driving figures. It is known to firmly attach to the chassis or support frame of the motor vehicle, a support arm, which carries at its end an additional support wheel. The jockey wheel can make a rolling contact with the reference surface in the critical driving situation to be trained. In a critical driving situation, such as the so-called "two wheel drive", two of the chassis wheels lose contact with the reference surface. So that the motor vehicle does not tilt out of the desired driving position on only two wheels, the support arm with support wheel supports the motor vehicle on the ground.

A driving exercise aid is known from DE 92 02 864 Ul, in which the exercise aid is designed as a skew trainer for motorcycles. The known skew trainer comprises a truss-like pipe system with telescopically displaceable rod sections extending away from the longitudinal side of the motorcycle and carrying at its end a support wheel.

It has been found in such Fahrübungshüfen that the accident risk is not negligible. The exercise aid only allows a fixed angle of inclination while driving. Since the required tendency to drive through curves is dependent on the driving speed, which varies according to experience, it often came to that extent accidents, as the motorcyclist due to the rigid support arms not sufficiently far in the curve may tilt as the speed of the motorcycle would actually have required. Furthermore, the operational capability of the exercise aid is limited to motorcycles.

WO 2005/100138 A2 discloses a motorcycle with lateral supports which are variable in their length. To adjust the length of a hydraulic drive is provided. WO 2005/044655 Al discloses an amusement vehicle having a substantially spherical inner frame structure on which two drive wheels and eight support wheels are arranged.

It is an object of the invention to provide a safer driving exercise aid for a hollow ball construction vehicle whose field of application can be extended and with which the motor vehicle driver can practice critical driving situations with a low accident risk.

This object is solved by the features of claim 1.

Thereafter, a drive for changing the length of the at least one support arm may be provided. The driver of the motor vehicle can already set the length of the support arm while driving in order to be able to approach the desired driving character gradually, or gradually to realize the driving figure without support. With the lent by the invention of the exercise aid driving flexibility when training the respective driving figure in the stationary hollow ball construction even the most inexperienced motor vehicle driver with sufficient confidence a driving feeling can be taught that is necessary to complete the driving figure correctly and safely.

For example, the driving force can be generated by hand, in particular by a manual cranking operation. Alternatively, the drive can be motorized. In both cases, the motor vehicle driver has the opportunity to set the length of the protective arm during the driving operation of the motor vehicle by means of the drive either manually or via a control member.

In a preferred embodiment of the invention, the length of the at least one support arm is infinitely adjustable, whereby the motor vehicle driver can get into the position of the desired driving figure gently and without sudden changes in the driving situation. Preferably, the at least one support arm is realized by a telescopic structure, in which a plurality of slidable pipe sections are provided. The support wheel can be articulated on the at least one support arm, in particular on the tube piece forming the free end of the support arm. In a telescopic structure, the drive is designed to displace the tube pieces to each other in the longitudinal direction of the support arm.

In a further development of the invention, a separate motorized drive in particular is provided for each support arm, which can be controlled either jointly by the motor vehicle driver or individually. The drive can be operated mechanically, electrically, hydraulically or pneumatically.

In a development of the invention, a device for controlling the drive is designed to change the length of the at least one support arm during the driving operation of the motor vehicle. The control device can be manually operated by the motor vehicle driver himself. Alternatively, the control device may be provided with a control circuit which determines both the position of the motor vehicle and automatically adjusts a certain Stützarmlänge based on a control program, so that the motor vehicle driver needs to concentrate mainly on the driving feel and less on the necessary driving control measures.

Preferably, the at least one support arm comprises a retracted rest position and a support position extended to its longitudinal direction. In the support position, the support wheel rolls off the reference surface as soon as the motor vehicle comes out of the stable driving position. In the rest position, the support arm is retracted in such a way that the exercise aid does not affect the driving operation of the motor vehicle even in the critical driving situation of a driving figure.

According to the invention, the exercise aid for a motor vehicle, such as a motorcycle or a passenger car, such as a quad, in a firmly anchored in the ground hollow ball construction, such as the so-called "Globe of Death" are used. According to the aspect of the invention, the exercise aid is formed by at least one upper-side support arm which is arranged substantially diametrically opposite the wheels of the chassis of the motor vehicle, in particular in the region of the motor vehicle roof, a roll bar or a body head guard, and at least partially perpendicularly in the normal horizontal operating position extends above. By attaching the support arm in particular Re essentially in the vertical direction or two support arms each from the upper part of the vehicle obliquely upwardly extending support arms, the motor vehicle is always fixed in the hollow ball construction with rolling engagement of the support wheel, so that the risk of tipping or falling when driving through the Hollow ball construction on all possible routes, especially in a looping ride, is excluded. In this way, even inexperienced motor vehicle drivers experience the experience of driving through the hollow ball construction and train safely.

In a chassis with at least three wheels, so for example a passenger car, a support arm may also extend away from a longitudinal side of the motor vehicle, ie transversely to the longitudinal direction of the motor vehicle.

Preferably, two, three or more support arms are provided, which surround the vehicle body transversely to the direction of travel in a substantially star-shaped. Of the support arms, at least one, preferably all, be variable in length, wherein for each support arm in each case a motor or a common motor for support arms can be provided.

Preferably, a plurality of adjacent support arms at an angular distance of about 120 °, 90 °, 45 ° or 30 ° to each other.

In a preferred embodiment of the invention, the exercise aid comprises a rolling structure, which is designed and attached to the motor vehicle, that it completely surrounds the body of the motor vehicle. At least one support arm with its support wheel is attached to the rolling structure.

Preferably, the Abrollbügelstruktur comprises a cross bar, which extends perpendicular to the longitudinal direction of the motor vehicle, ie to the direction of travel. Furthermore, the Abrollbügelstruktur include a single handle, which extends in particular in the longitudinal direction, ie in the direction of travel of the vehicle.

For a stable construction of the roll bar structure, a cage is provided, which is to be mounted on the motor vehicle. On the cage outside of the longitudinal and / or transverse bracket are attached. To ensure a safe rolling of a vehicle overturning, extend the longitudinal and / or the transverse bow circular outside around the motor vehicle. The longitudinal and / or the transverse bar can carry both the support arm and the associated motorized drive. In particular, a braking device can be provided for each drive or each support wheel, which can cause a deceleration of the motor vehicle when rolling the motor vehicle on the support wheels.

Thus, the support wheels forward the rolling motor vehicle safely in the direction of travel and can lead, the at least one support wheel on the outside of the transverse and / or longitudinal bracket is arranged such that when a change in position, the motor vehicle from the normal operating position in the critical, especially unstable or tilted, driving situation only the jockey wheel comes into contact with the reference surface and not the transverse and / or single bar or the cage of the roll bar structure. In particular, the drive can be designed to perform a steering of the motor vehicle in a stable driving situation by placing the respective support wheels.

Preferably, the at least one support wheel is aligned with the crossbar according to the direction of travel of the chassis wheels. The same may also apply to the support brackets arranged on the longitudinal bracket. The support wheels can be steerable, in particular in case of rolling contact via the drive for steering the overturned motor vehicle.

Furthermore, the invention relates to a motor vehicle, such as a motorcycle or a passenger car, for traveling on a stationary reference surface, such as a horizontal driving surface, the inside of a hollow ball structure or the like, with a driving aid according to the invention.

FIGS. 1 to 3 show a driving aid with the reference number 1 in a first preferred embodiment. The exercise aid 1 is designed to be mounted around a motor vehicle (not shown in FIGS. 1 to 3) as a body protector, such as a motorcycle or a passenger car.

The exercise aid 1 comprises a substantially rectangular cage structure 3 with height carriers 5, cross members 7 and longitudinal members 9. On the outside of the cage structure 3, both a circular cross bar 11 and a circular single lever 13 are rigidly fixed, so that the motor vehicle, for example, in a failed critical driving figure on the outside of the transverse and single handle can harmlessly roll.

On the outside of the cross bar 11 star-shaped Abrollräder are fixed, which extend concentrically to the center M of the cross bar 11 away and on the cross bar 11 via an extendable support arm (not shown) off and retractable. The crossbar 11 carries eight arranged at an angular distance of about 45 ° outside Abrollräder 17, of which by way of example a Abrollrad 17 in Fig. 5 is shown in more detail. The Abrollrad 17 ensure lateral rolling of the exercise aid 1. The Abrollrad 17 includes a rotatably mounted tire 19 which is connected via a variable length support arm 21 with a flange 23 which is fixed to the crossbar 11.

The circular longitudinal bracket 13 is provided with Abrollrädern 25 which are rigidly secured to the outside of the longitudinal bracket 13. An example of a Abrollrad 25 is shown in Fig. 6. The Abrollrad 25 includes a rotatably mounted tire 27 which is movably connected via a variable length support arm 29 with a flange 31. The flange 31 is rigidly secured to the longitudinal bracket 13. The Abrollrad 25 serves to ensure a rolling of the exercise aid 1 in the direction of travel of the motor vehicle, which corresponds in Fig. 1 of the front view direction.

According to the invention, a variable-length support arm 35 is also provided, which is rigidly secured to the cage structure 3. Details of the support arm 35 according to the invention are shown in FIG. The base 37 of the support arm 35 is adjustably mounted on the height support 5 of the cage structure 3, wherein the base 37 carries an electric motor 39. The electric motor 39 has a mechanical drive 41, which causes the change in length of the support arm 35. The length variability of the support arm 35 is realized by a telescopic structure 43, which comprises a plurality of mutually displaceable pipe sections 45 to 53. The near-base pipe section 45 has the largest diameter and can accommodate the pipe sections 47 to 53 displaceable in one another.

In the pipe section 51, a spring damping 55 is integrated, the shock load variable amplitudes and high-frequency vibrations, which act on the support arm, cushion and dampen. At the end pipe section 53, a support wheel 57 is pivotally mounted about an axis of rotation E (rotation axis D). The electric motor 39 causes the extension and retraction of the support wheel 57 away from the cage structure and toward the latter. In this case, the electric motor 39 can set the position of the support wheel 57 stepless.

It can also be provided a stepping motor, the step size is adjustable. In the fixed state of the support wheel 57, a displacement of the pipe sections 45 to 53 is blocked, wherein a damping path is permitted within the tubular piece 51 for cushioning impacts acting on the support arm.

As shown in Fig. 1, all support arms 21, 29 of the Abrollräder 17, 25 shown in a retracted position. It is also conceivable to carry out the support arms 21, 29 in a non-extendable manner. In Fig. 1 it is further seen that the unwind points of the retracted Abrollräder 17 and 25 are on a circular line K to the center M, to ensure a safe unwinding of the exercise aid. Only the support arm 35 is shown in an extended position, in which the support wheel 57 is located radially outside the circle K of Abrollräder 17 and not shown in Fig. 2 circular line L of Abrollräder 25.

In FIGS. 7a to 7c, the use according to the invention of the exercise aid 1 according to the invention in a passenger vehicle 61 is shown. The exercise aid 1 is arranged around the outer body 63 with roof and side part around, wherein the cage structure 3 is attached to supporting chassis parts of the passenger vehicle 61. The passenger vehicle 61 has a chassis not shown in detail, are arranged on the four chassis wheels 65, 66, of which only two are shown in the figures 7a to 7c. In Fig. 7a of the passenger car is shown in a normal operating situation in which all four chassis wheels 65, 66 are in rolling contact with a horizontal driving surface H.

In Fig. 7a, the support arm 35 is partially extended, wherein due to the horizontal driving position of the passenger car 61, the support wheel 57 is at a distance from the driving surface H. All the other Abrollräder 17, 25 are also not in contact with the driving surface H. In the illustrated in Fig. 7a configuration of the exercise aid 1, the passenger 61 controlling operator 67 certain driving figures train, such as the so-called "two wheels drive" in which the motor vehicle drives, for example, only on the left-hand pair of wheels (65) or on the right-hand pair of wheels (66). For the use of the exercise aid 1 in a passenger car for this driving figure, the exercise aid 1 is to be configured such that the support arm 35 extends from the longitudinal side of the passenger car to the outside, as shown in Figures 7a to 7c.

In order to gradually approach the critical equilibrium position in which the car 61 is balanced for the "two wheels drive", the operator 67 can vary the length of the support arm 35 by actuating a control device in the car 61 (not shown). ming. In Fig. 7b a widely extended support arm 35 can be seen, which allows a first balance position of the car 61. In this critical driving situation, the right pair of undercarriage 66 loses contact with the driving surface H, with the support wheel 57 making contact with the driving surface H to stabilize the driving operation of the passenger car 61. In the driving position shown in Fig. 7b, a motor vehicle driver can easily hold the car in the critical driving situation and gets a feel for this critical driving situation.

By operating the control device, not shown, the length of the support arm 35 can be increased and decreased, whereby different critical driving situations and driving figures are risk-free for the operator 67 can be realized. In Fig. 7c a retracted support arm position is shown, which allows a stronger tilting of the car 61 to the driving surface H.

In FIGS. 8a to 8c, the driving exercise aid 1 according to the invention is modified relative to the exercise aid 1 according to FIGS. 7a to 7c in that it is mounted on a motorcycle 71, wherein the support arm 35 extends parallel to the direction of travel of the motorcycle 71. In this case, the support wheel 57 is rotatably mounted to the support arm 35 so that the support wheel 35 can perform a rolling motion in the direction of travel of the motorcycle 71.

In Fig. 8a, the support arm 35 is arranged on the rear side of the motorcycle 71, with which driving figures, such as the so-called "wheely" - one-wheel drive on the rear drive wheel 75 - are executable.

In Fig. 8b a modified exercise aid 1 is shown with a handlebar side arranged support arm to practice critical driving situations in which the motorcycle 73 to perform a so-called "stoppy", in which during the braking process, the rear wheel 75 loses contact with the driving surface H and the motorcyclist 73 brakes the motorcycle 71 on the front wheel 79 braking. In Fig. 8b, this critical driving situation is shown, wherein the long extended support arm 35 and standing in contact with the driving surface H support wheel 57 allows an inclination of the motorcycle 71 up to 30 °. In order to increase the steepness of the motorcycle 71 in the figure "stoppy" in order to increase the spectacularity of the driving figure, the motorcyclist 73 already during driving shorten the length of the support arm 35, which is indicated in Fig. 8c, so as to larger angles of the motorcycle relative to the driving surface H to allow. In FIGS. 9a to 9c, the exercise aid 1 is configured as a skew trainer. In this case, the support arm 35 is arranged transversely to the direction of travel of the motorcycle on the left side or the right side of the frame. In order to secure low-speed banking for the rider 73, the support arm 35 is widely extended, as shown in FIG. The shorter the support arm 35, the stronger the inclination of the motorcycle 71 may be. Since the motorcyclist 73 can operate the length of the support arm 35 due to the driving of the motor 39 to extend and retract the support arm 35 while driving, the motorcyclist can easily approach the optimum critical banking position.

FIGS. 10a to 17b show a further possible use of the exercise aid according to the invention, namely the use in the so-called "Globe of Death", a hollow ball construction fixedly installed on the floor via support legs, in the stuntmen driving exercises with motor vehicles, such as passenger cars and motorcycles. The hollow ball construction comprises a part-spherical door, over which the motor vehicle passes into the hollow ball construction.

In FIGS. 10a to 17b, the hollow ball construction is indicated by the reference numeral 81. The embodiment of the exercise aid according to the invention shown in FIGS. 10 a and 10 b is very similar to the exercise aid 1 shown in FIGS. 1 to 3. For better readability of the description of the figures, identical reference symbols are used for identical and similar exercise aids according to FIGS. 10 a and 10 b, which are increased by 100.

The exercise aid 101 differs from the exercise aid 1 in that the support arm 135 is disposed on the cross member 107 of the cage structure 103 above the roof of the car 161 and extends vertically in the height direction. In Fig. 10a, the support arm 135 is extended, so that the support wheel 157 is in contact with the inside 83 of the hollow ball construction 81. The extension and retractability of the support arm 135 has the advantage of gradually dive-free training and facilitates the retraction of the motor vehicle in the hollow ball construction 81st

With the four chassis wheels 165 and the support wheel 157, the drive unit of passenger cars 161 and exercise aid 101 for driving through the hollow ball construction 81 is statically determined in each position. In Fig. 10b a critical driving situation of the passenger car 161 is shown, in which the passenger car 161 has such a high speed that it can assume a horizontal position.

In Fig. I Ia and Ib I, a further embodiment of an exercise aid according to the invention is shown. For better readability of the description of the figures, the same reference numerals as in FIGS. 10a and 10b are used, the reference numerals being increased by 100 compared to those of FIGS. 10a and 10b.

The exercise aid 201 according to the invention differs from the exercise aid 101 in that two support arms 235a and 235b are arranged at an angle of 120 ° to each other. Both support arms 235a and 235b are fastened to the cross member 207 of the support structure 203 and extend transversely to the direction of travel and in the height direction above the roof area of the passenger car 261.

The direction indicators apply to the normal driving operating position shown in Fig. 1 Ia.

In Fig. 12a and 12b, a further embodiment according to the invention of a driving exercise aid is shown, wherein reference numerals are used for identical and identical components, which are compared to those of FIG. 1 Ia and I Ib increased by 100.

The exercise aid 301 differs from the exercise aid 201 of FIGS. 11a and 11b in that three support arms 335a to 335c are attached to the cross member 307. The support arms 335a and 335c extend exclusively in the transverse direction, that is to say perpendicular to the direction of travel, which corresponds to the front-view direction of FIGS. 12a and 12b. The support arm 335b extends only in the height direction, as the support arm 135 according to the exercise aid according to FIGS. 10a and 10b. In Fig. 12b a horizontal critical driving situation is shown, in which the support arms 335a to 335c securely hold the passenger car 361 in position, without it being important for the operator to properly operate the passenger car 361.

The exercise aid shown in FIGS. 13a and 13b differs from the exercise aid 101 according to FIGS. 10a and 10b only in that it is designed for use on a motorcycle 171.
