STEERING SYSTEM FOR A MOTOR VEHICLE, PREFERABLY
DRIVING SCHOOL MOTOR VEHICLE
Description [0001] The invention relates to a steering system for a motor vehicle, preferably for a driving school motor vehicle.
[0002] Motor vehicles with steering systems with an addition or double steering means for driving school purposes are already known in the prior art. Such steering systems comprise the actual series-mounted steering train for a person learning to drive, wherein the series-mounted steering train usually has a steering wheel for steering the vehicle and a steering gear mechanism. The steering wheel is connected to the steering gear mechanism, wherein the steering gear mechanism passes on the steering movements of the steering wheel to wheels of the motor vehicle. In addition to the actual series-mounted steering train, these steering systems usually also provide an auxiliary steering train for a driving school instructor, which auxiliary steering train is composed of an additional steering wheel and an additional connection to the steering gear mechanism. By means of the auxiliary steering train it is possible, for example, in a driving school mode of a motor vehicle, for the driving instructor who is usually seated on a front passenger seat of the motor vehicle to be able to engage actively in the steering processes of the person learning to drive who is usually seated on the driver’s seat.
[0003] In practice, auxiliary steering trains are known in which the torque is transmitted from the additional steering wheel to the series-mounted steering train either via a pure train drive or via cardan shafts with angular gears. The problem here is in particular that this requires the necessary space in the motor vehicle, with the result that the implementation depends to a great extent on the installation space situation in the motor vehicle.
[0004] In other auxiliary steering trains which are known from practice, the torque is transmitted hydrostatically to the series-mounted steering train from the additional steering wheel. However, it is virtually impossible here to avoid introducing undesired additional power into the steering system. Therefore, there is usually hydraulic boosting, which is often not desired. Furthermore, a hydraulic pump which entails additional costs and additional weight and usually has to operate electrically is usually necessary for this.
AH25(13770051_l):KEH
2017248570 20 Oct 2017 [0005] An object of the invention is to provide an improved and/or an alternative steering system for a motor vehicle, preferably a steering system by means of which a torque of a frontseat-passenger-side steering device can be transmitted to a steering gear mechanism relatively independently of the installation space situation of the motor vehicle, specifically in particular free of boosting and/or in a purely mechanical fashion.
[0006] This object can be achieved with the features of the independent claim. Advantageous developments of the invention can be found in the dependent claims and the following description of preferred embodiments of the invention.
[0007] The invention relates to a steering system for a motor vehicle, preferably for a driving school motor vehicle. The motor vehicle is preferably a passenger car or a utility vehicle, e.g. a bus or a lorry, in particular for driving school purposes.
[0008] The steering system comprises a steering gear mechanism via which wheels of the motor vehicle can preferably be steered.
[0009] The steering system also comprises a driver-side steering device, e.g. with a steering wheel, for steering the motor vehicle via the steering gear mechanism. The driver-side steering device preferably serves for use by a person learning to drive and/or is part of a series-mounted steering train.
[0010] The steering system also comprises a front-seat-passenger-side steering device, e.g. with an additional steering wheel, for steering the motor vehicle expediently also via the steering gear mechanism. The front-seat-passenger-side steering device preferably serves for use by a driving instructor and/or is part of an auxiliary steering train.
[0011] The steering system is defined, in particular, by the fact that the front-seat-passengerside steering device is connected to the steering gear mechanism via a shaft connection which is flexible at least in part of its length (expediently a flexible shaft) for transmitting a torque. The flexible shaft connection can therefore be expediently embodied in a flexible manner over essentially its entire longitudinal extent or only partially.
[0012] With an at least partially flexible shaft connection the torque can be transmitted to the driver’s side, in particular the steering gear mechanism, relatively independently of the front seat
AH25(13770051_l):KEH
2017248570 20 Oct 2017 passenger’s side. All that has to be considered is, in particular, the minimum bending radius of the flexible shaft connection. Furthermore, a purely mechanical steering system, preferably with a transmission ratio of 1:1, can be implemented by means of the flexible shaft connection, with the result that undesired boosting of the steering can expediently be avoided.
[0013] The steering gear mechanism is preferably provided for transmitting a steering movement, generated by means of the driver-side steering device - or by means of the frontseat-passenger-side steering device when necessary in a driving school or in an emergency situation - to wheels of the motor vehicle. It is possible for the steering gear mechanism to comprise e.g. a steering rack steering system, a worm gear steering system, a screw-type steering system or a ball-and-nut steering system, which can be assisted e.g. electrically or hydraulically.
[0014] The steering system, in particular the front-seat-passenger-side steering device, permits, e.g. in a situation in which a person learning to drive does not have the motor vehicle under control for a certain time, a driving instructor to assume control of the motor vehicle selectively by means of his own steering movements without said the driving instructor having to take hold of the driver-side steering device which is at a distance from the front passenger seat.
[0015] The flexible shaft connection can be arranged e.g. in a flexible protective sheath, with the advantage that the flexible shaft connection can be protected against dirt, moisture or other rust-promoting influences. The protective sheath can also permit a situation in which the flexible shaft connection is not in direct contact with any adjacent components.
[0016] It is possible for the front-seat-passenger-side steering device to be connected to the flexible shaft connection via a torque-transmitting device for transmitting a torque, and for the torque-transmitting device preferably to have a steering cardan shaft. The torque-transmitting device can comprise, for example, a longitudinally adjustable steering cardan shaft with at least one cardan joint.
[0017] In a further embodiment of the invention, a bearing element (e.g. a flange bearing) in particular for supporting the torque-transmitting device and/or the flexible shaft connection, can be arranged relative to the transmitting direction of the torque of the front-seat-passenger-side steering device, between the torque-transmitting device and the flexible shaft connection. The support which can be produced by means of the bearing element has, in particular, the advantage
AH25(13770051_l):KEH
2017248570 20 Oct 2017 that radial forces which result from the rotation of the torque-transmitting device cannot be passed on, or can only be passed on in a highly reduced fashion, to the flexible shaft connection.
[0018] In a further embodiment of the invention, the torque-transmitting device can be connected to the bearing element and/or to the flexible shaft connection via an adaptor.
[0019] According to a further embodiment of the invention, the steering system can comprise an overload coupling, e.g. by means of which the front-seat-passenger-side steering device and/or the flexible shaft connection can be decoupled from the steering gear mechanism, preferably in order to protect the flexible shaft connection against overloading and/or in the case of a malfunction of the auxiliary steering train which can be controlled by the front-passenger-seatside steering device. This has e.g. the advantage that the auxiliary steering train can be decoupled from the series-mounted steering train in the event of damage. This preferably protects, on the one hand, the flexible shaft connection against excessively high torques. On the other hand, the entire auxiliary steering train can preferably be decoupled from the seriesmounted steering train in the event of a malfunction, for example when the auxiliary steering train locks. However, the series-mounted steering train expediently continues to be capable of being operated in this context.
[0020] The overload coupling can be implemented, for example, in the form of a play free torque limiter with or without automatic re-engagement. It is conceivable for the overload coupling to be able to be implemented as e.g. a spring-prestressed ball-catch coupling, a springprestressed ball-catch module coupling, a spring-prestressed friction clutch, a magnetic continuous slip clutch or a pneumatic or electromagnetic clutch.
[0021] It is possible for the overload clutch to be preferably manually activated and deactivated in order to activate or deactivate a steering system of the motor vehicle via the front-seatpassenger-side steering device.
[0022] The overload clutch can e.g. be deactivated manually if the auxiliary steering train is not required over a relatively long period of time. It is therefore conceivable for the manual decoupling and the manual coupling to be activated or deactivated by means of an activation device from the interior of the motor vehicle, e.g. by a driving instructor.
AH25(13770051_l):KEH
2017248570 20 Oct 2017 [0023] In a further embodiment of the invention, the steering system preferably comprises a bearing system (e.g. flange bearing system) for supporting the flexible shaft connection at its end region facing the steering gear mechanism. The bearing system serves, in particular, to protect the flexible shaft connection against radial forces which can result e.g. from torque transmission by the rotational direction-reversing device mentioned below, in particular the gearwheels thereof.
[0024] According to a further embodiment of the invention, the driver-side steering device can be connected to the steering gear mechanism via a torque-transmitting device for transmitting a torque, wherein the torque-transmitting device can preferably have a steering cardan shaft. It is possible that the torque-transmitting device comprises, for example, a longitudinally adjustable steering cardan shaft with at least one cardan joint.
[0025] According to a further embodiment of the invention, the steering system comprises e.g. a bearing system (e.g. a flange bearing) for supporting the torque-transmitting device at its end region facing the steering gear mechanism and/or for protecting the steering gear mechanism against radial forces which can be transmitted by the flexible shaft connection.
[0026] According to a further embodiment of the invention, a rotational direction-reversing device (e.g. a gearwheel pair) for reversing the rotational direction of the torque of the flexible shaft connection is arranged relative to the transmitting direction of the torque of the front-seatpassenger-side steering device, between the flexible shaft connection and the steering gear mechanism. The rotational direction-reversing device is preferably embodied as a gear drive and/or is arranged relative to the transmitting device of the torque of the front-seat-passengerside steering device, between the overload coupling and the steering gear mechanism. The rotational direction-reversing device has, in particular, the advantage that a rotational movement of the flexible shaft connection can be transformed into a rotational movement in the opposite direction. On the other hand, the rotational direction-reversing device is preferably provided to transmit a torque which is present at the flexible shaft connection to the steering gear mechanism.
[0027] According to a further embodiment of the invention, the steering system preferably comprises a bearing profile, preferably for mounting fixed to the motor vehicle, and at least one of the following is secured by means of the bearing profile: the steering gear mechanism, the
AH25(13770051_l):KEH
2017248570 20 Oct 2017 overload coupling, the bearing system for supporting the flexible shaft connection, the bearing system for supporting the torque-transmitting device, and/or the rotational direction-reversing device.
[0028] It is possible that the torque of the steering device can be transmitted substantially free of the transmission ratio to the steering gear mechanism via the flexible shaft connection. This has the advantage that the flexible shaft connection can have a transmission ratio of as it were 1:1.
[0029] According to yet a further embodiment of the invention, the driver-side steering device and/or the front-seat-passenger-side steering device can be connected to the steering gear mechanism in a purely mechanical fashion in order to transmit a torque.
[0030] As a result of the transmission without a transmission ratio and/or the purely mechanical transmission it is possible to achieve a saving e.g. in terms of additional components and costs, since, for example, hydrostatic supporting systems composed of, for example, hydraulic pumps, hydraulic lines, a hydraulic motor and an equalizing container for hydraulic fluid are not necessary. The hydraulic components frequently have to be operated by means of electrical systems which give rise to additional weight and additional power consumption in the vehicle. It is therefore possible to achieve a saving in space in the vehicle.
[0031] It is possible for the flexible shaft connection to be bent by an angle of 180°, e.g. plus/minus 15° or 30°.
[0032] The invention also comprises a motor vehicle, preferably a driving school motor vehicle, having a steering system as disclosed herein. The motor vehicle can be e.g. a passenger car or a utility vehicle, in particular a bus or a lorry.
[0033] The embodiments and features of the invention described above can be combined with one another. Other advantageous developments of the invention are disclosed in the dependent claims or emerge from the following description of preferred embodiments of the invention in conjunction with the appended figures. In the drawings:

2017248570 20 Oct 2017 [0035] Figure 2 shows a plan view of the steering system in Figure 1, [0036] Figure 3 A shows a view of a detail of part of the steering system shown in Figures 1 and 2, and [0037] Figure 3B shows a view of a detail of another part of the steering system shown in Figures 1 and 2.
[0038] Figures 1 and 2 show a steering system 100 for a motor vehicle, in particular a driving school motor vehicle, according to an embodiment of the invention.
[0039] The steering system 100 comprises, with joint reference to Figures 1 and 2, a steering gear mechanism 2, a driver-side steering device 1 with a steering wheel for steering of the motor vehicle by a person learning to drive (male/female) via the steering gear mechanism 2 and a front-seat-passenger-side steering device 4 with a steering wheel for steering of the motor vehicle by a driving instructor (male/female), likewise via the steering gear mechanism 2.
[0040] By means of the front-seat-passenger-side steering device 4 it is possible, in particular in the case of a driving school mode of the motor vehicle, that the driving instructor who is usually seated on a front passenger seat of the motor vehicle can actively engage in the steering processes of the person learning to drive who is usually seated on the driver’s seat. In this way, the front-seat-passenger-side steering device 4 permits, e.g. in a situation in which the person learning to drive does not have the motor vehicle under control for a certain time, the driving instructor to assume control of the motor vehicle selectively by means of his own steering movements without said driving instructor having to take hold of the driver-side steering device 1 which is at a distance from the front passenger seat.
[0041] The front-seat-passenger-side steering device 4 is connected to the steering gear mechanism 2 via a shaft connection 5 which is flexible at least in part of its length (flexible shaft) and has the purpose of transmitting a torque. In the embodiment shown, the flexible shaft connection 5 is bent by an angle of essentially 180°.
[0042] The front-seat-passenger-side steering device 4 is connected to the flexible shaft connection 5 via a torque-transmitting device 14 for transmitting a torque. The torquetransmitting device 14 has a steering cardan shaft with a cardan joint.
AH25(13770051_l):KEH
2017248570 20 Oct 2017 [0043] A bearing element 13 is arranged, relative to the transmitting direction D (illustrated schematically in Figure 2) of the torque of the front-seat-passenger-side steering device 4, between the torque-transmitting device 14 and the flexible shaft connection 5, on the one hand for mounting fixed to the motor vehicle, e.g. by means of a securing means 15, and on the other hand for supporting an output-side end of the torque-transmitting device 14 and an input-side end of the flexible shaft connection 5.
[0044] The torque-transmitting device 14 is connected to the bearing element 13 and/or to the flexible shaft connection 5 via an adaptor 12.
[0045] A torque of the steering device 4 can be transmitted via the flexible shaft connection 5 without a transmission ratio and therefore with a transmission ratio of 1:1 to the steering gear mechanism 2.
[0046] The front-seat-passenger-side steering device 4 and the flexible shaft connection 5 can be decoupled from the steering gear mechanism 2 via an overload clutch 11, e.g. in order to protect the flexible shaft connection 5 against overloading and in the event of a malfunction of the auxiliary steering train which can be controlled by the front-seat-passenger-side steering device 4. The overload coupling 11 can be activated and deactivated manually in order to be able to activate or deactivate a steering system of the motor vehicle via the front-seat-passengerside steering device 4.
[0047] The driver-side steering device 1 is connected to the steering gear mechanism 2, e.g. to an axle 8 of the steering gear mechanism 2, via a torque-transmitting device 3 for transmitting a torque. The torque-transmitting device 3 preferably comprises a steering cardan shaft with a cardan joint.
[0048] Both the driver-side steering device 1 and the front-seat-passenger-side steering device 4 serve to transmit a torque to the steering gear mechanism 2 in a purely mechanical fashion.
[0049] The steering system 100 comprises a rotational direction-reversing device 6, 7 for reversing the rotational direction of the torque of the flexible shaft connection 5. The rotational direction-reversing device 6, 7 is arranged, relative to the transmitting direction D (illustrated schematically in Figure 2) of the torque of the front-seat-passenger-side steering device 4, between the flexible shaft connection 5 and the steering gear mechanism 2. The rotational
AH25(13770051_l):KEH
2017248570 20 Oct 2017 direction-reversing device 6, 7 is embodied as a gear drive with two gearwheels 6, 7 which are in engagement and is arranged, relative to the transmitting direction D (illustrated schematically in Figure 2) of the torque of the front-seat-passenger-side steering device 4, in particular between the overload coupling 11 and the steering gear mechanism 2. The gearwheel 7 is coupled here in a rotatably fixed fashion to the axle 8 of the steering gear mechanism 2.
[0050] The flexible shaft connection 5 is mounted at its end region E facing the steering gear mechanism 2 by means of a bearing system 10 which is embodied as a flange bearing, while the torque-transmitting device 3 is also mounted at its end region facing the steering gear mechanism 2 via a bearing system 9 which is embodied as a flange bearing.
[0051] A bearing profile L for mounting fixed to the motor vehicle secures the steering gear mechanism 2, the bearing system 10 for supporting the flexible shaft connection 5, the bearing system 9 for supporting the torque-transmitting device 3, and the rotational direction-reversing device 6, 7.
[0052] The flexible shaft connection 5 is secured at its output-side end by means of two lock nuts. The overload coupling 11 is seated between the bearing system 10 for supporting the flexible shaft connection 5 and the output-side end of the flexible shaft connection 5.
[0053] The bearing system 10 serves here, in particular, to protect the flexible shaft connection 5 against radial forces which can result e.g. from torque transmission by the rotational directionreversing device 6, 7, particular the gearwheels thereof.
[0054] Figure 3 A shows a perspective view of a detail of a part of the steering system 100 which is shown in Figures 1 and 2. Figure 3A shows, in particular, the region with the torquetransmitting device 14, the adaptor 12, the securing means 15, the bearing element 13 and the flexible shaft connection 5.
[0055] Figure 3B shows a perspective view of a detail of another part of the steering system 100 which is shown in Figures 1 and 2. Figure 3B shows, in particular, the region with the overload coupling 11, the rotational direction-reversing device 6, 7, the bearing system 10 for supporting the flexible shaft connection 5, the bearing system 9 for supporting the torque-transmitting device 3, the steering gear mechanism 2 including the axle 8 of the steering gear mechanism 2 and the bearing profile F.
