Description

The invention relates to a utility vehicle with an electrical storage device according to the preamble of patent claim 1.

Such a commercial vehicle, for example, is already the DE 10 2012 000 812 A1 to be known as known. The commercial vehicle has a frame, which comprises, for example, two longitudinal members spaced apart in the vehicle transverse direction. The frame comprises, for example, at least one cross member, via which the longitudinal members are connected to each other.

The commercial vehicle also has at least two axles arranged one behind the other in the vehicle longitudinal direction, which comprise respective wheels. The wheels roll off during a drive of the utility vehicle along a roadway on the road. In other words, the wheels are ground contact elements, via which the utility vehicle is supported on a roadway or is on the road. If the commercial vehicle drives along the roadway, the wheels roll off the road so that the commercial vehicle rolls over the wheels on the road and can roll along the road.

Furthermore, the utility vehicle comprises an electrical storage device, which is held at least indirectly on the frame, for storing electrical current, with which at least one electric machine for driving the utility vehicle can be supplied. The commercial vehicle is thus designed, for example, as an electric vehicle or hybrid vehicle, since the commercial vehicle by means of the electric machine, in particular in a motor operation of the electric machine, can be driven. In order to drive the commercial vehicle by means of the electric machine, the electric machine is supplied with electrical energy or electric current stored in the electrical storage device.

Object of the present invention is to develop a commercial vehicle of the type mentioned in such a way that a particularly high payload and a particularly high range, over which the commercial vehicle can be driven by means of the electric machine, can be realized.

This object is achieved by a commercial vehicle with the features of claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

In order to develop a commercial vehicle specified in the preamble of claim 1 type such that a particularly high payload of the commercial vehicle and a particularly high range, over which the commercial vehicle can be driven by means of the electric machine can be realized, it is provided according to the invention Commercial vehicle has a sidecar arranged between the axles, via which the electrical storage device is held on the frame. The sidecar has at least two other wheels, which roll when driving on the road. In other words, when the utility vehicle is driven along a roadway, the utility vehicle is supported on the roadway via the wheels of the axles, and the wheels roll on the roadway so that the utility vehicle rolls over the wheels of the axles on the roadway. In this case, the other wheels of the sidecar roll on the road, so that the electric storage device held on the sidecar is supported on the sidecar and thus on the other wheels of the sidecar on the road.

As a result, an impairment of the payload of the utility vehicle available for transporting goods to be transported caused by the electrical storage device can be prevented, so that a particularly high payload available can be realized. Furthermore, a particularly high storage capacity of the electrical storage device can be realized, so that a particularly high amount of electrical energy or electrical current can be stored in the electrical storage device. As a result, it is possible to realize a particularly high range, via which the commercial vehicle can be driven by means of the electric machine and thus by means stored in the electrical storage device electrical energy. Since the sidecar and in particular its other wheels are arranged in the vehicle longitudinal direction between the wheels of the axles, caused by the sidecar length increase of the utility vehicle can be avoided, so that the length of the utility vehicle can be kept low. Further, it is possible to disassemble the electric storage device particularly easily from the sidecar and to mount it to the car, so that, for example, the electric storage device can be exchanged when the electric storage device is discharged and replaced with another charged electric storage device.

This replacement of the electrical storage device can be done in a particularly simple manner and thus timely. This can cause an excessively long stoppage of the Utility vehicle to charge the electrical storage device can be avoided. For example, the sidecar can be arranged at least substantially in the middle of the frame, in particular with respect to the vehicle longitudinal direction, so that, for example, a particularly high rigidity of the frame can be realized.

The invention is based in particular on the recognition that electric or hybrid vehicles require electrical storage devices in order to be able to electrically drive the respective hybrid or electric vehicle. In this case, the range over which the respective vehicle can be electrically driven usually depends on the size of the electrical storage device, since with increasing size of the electrical storage device, an increasing storage capacity of the electrical storage device can be realized. For commercial vehicles in addition to the range but also the payload plays a very important and especially economic role. By using the sidecar, both a particularly high payload and a long range can be realized. Since the sidecar and in particular its other wheels are arranged between the wheels of the axles, the sidecar also does not affect the maneuverability of the utility vehicle, for example during parking operations and in traffic congestion. This means that the driver of the utility vehicle can maneuver this particularly easy.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

This drive train comprises at least one electric machine which can not be seen in the figures and which can be operated, for example, in an engine operation and thus as an electric motor. In its engine operation, the electric machine, the commercial vehicle 10 drive, so the commercial vehicle 10 by means of the electric machine and thus is electrically driven. Here is the commercial vehicle 10 For example, designed as a hybrid or electric vehicle.

In synopsis with 6 is recognizable that the commercial vehicle 10 a first axle in the form of a front axle 20 and a second axle in the form of a rear axle 22 has, wherein the axes are arranged in the vehicle longitudinal direction one behind the other or consecutively. This shows the front axle 20 Wheels of which in 6 the left in the vehicle transverse direction wheel 24 is recognizable. Out 1 is recognizable that the rear axle 22 a plurality of wheels 26 having. The wheels 24 and 26 are at least indirectly rotatable on the frame 12 held and ground contact elements, over which the commercial vehicle 10 - If this is on a road or driving along the road - is supported on the road. Will the commercial vehicle 10 driven along the aforementioned lane, so roll the wheels 24 and 26 on the road, so the commercial vehicle 10 over the wheels 24 and 26 Rolls on the road and can roll along the road. The wheels 24 are front wheels as they are the front axle 20 assigned. Here are the wheels 26 Rear wheels, as they are the rear axle 22 assigned.

Especially good 2 . 4 and 5 is recognizable that the commercial vehicle 10 one in total with 28 has designated electrical storage device, which is designed for example as a battery. By means of the electrical storage device 28 or in the electrical storage device 28 Electricity or electrical energy can be stored. The higher the storage capacity of the electrical storage device 28 is, the higher the amount of electrical energy, which in the electrical storage device 28 can be stored. In order to operate the aforementioned electric machine in its engine operation, the electric machine is included in the electric storage device 28 stored electrical energy supplied. This means that the electric machine, in particular in its engine operation, by means of the electrical storage device 28 is supplied with electric power, thereby the commercial vehicle 10 to be able to drive by means of the electric machine.

To now a particularly high, available for the transport of cargo payload of the utility vehicle 10 and a particularly high range, over which the commercial vehicle 10 Being powered by the electrical energy to be able to realize, is - how very good 2 recognizable - a sidecar 30 provided, which in the vehicle longitudinal direction between the front axle 20 and the rear axle 22 is arranged. The sidecar 30 is with the frame 12 connected and thus to the frame 12 held. Further, the electric storage device 28 on the sidecar 30 held, so that the electrical storage device 28 over the sidecar 30 with the frame 12 coupled and attached to the frame 12 is held. This means that the electrical storage device 28 under the mediation of the sidecar 30 on the frame 12 and thus with the commercial vehicle 10 overall can be carried.

The sidecar 30 has two spaced apart in the vehicle transverse direction further wheels 32 on, which in the vehicle longitudinal direction between the front axle 20 and the rear axle 22 and are arranged in particular between the front wheels and rear wheels. Also the other wheels 32 are ground contact elements, about which the sidecar 30 and thus the electrical storage device 28 are supported on the aforementioned roadway when the commercial vehicle 10 is on the road or is driven along the road. Will the commercial vehicle 10 driven along the road, so roll the wheels 24 and 26 as well as the other wheels 32 on the roadway, leaving the electrical storage device 28 , in particular their weight, on the sidecar 30 and especially about the wheels 32 of the sidecar 30 is supported on the roadway.

Out 3 is recognizable that the sidecar 30 an example formed as a plate base element 34 which is attached to the frame 12 held, in particular fastened, is. Furthermore, the sidecar includes 30 a holding element 36 , which with the base element 34 is coupled. Here is the holding element 36 for example, in the vehicle vertical direction relative to the base element 34 and thus relative to the frame 12 , in particular translationally, movable and / or about the vehicle vertical direction relative to the base element 34 and thus relative to the frame 12 rotatable. For example, one on the base element 34 held guide element 38 provided along which the holding element 36 in the vehicle vertical direction relative to the base member 34 is movable, wherein the holding element 36 by means of the guide element 38 to be led. To the relative movements between the base element 34 and the holding element 36 For example, in particular in vehicle vertical direction, for example to dampen and / or spring, at least one between the base element 34 and the holding element 36 arranged spring and / or damping element provided, for example, on the one hand with the base element 34 and on the other hand with the holding element 36 connected is.

Alternatively or additionally, it is provided that the retaining element 36 rotatable on the guide element 38 is held. Alternatively, it can be provided that the holding element 36 rotatably with the guide element 38 is connected, but wherein the guide element 38 rotatable with the base member 34 connected is. Thus, it is for example provided that the holding element 36 , in particular via the guide element 38 , rotatable on the base element 34 is held, so that the retaining element 36 and therefore the wheels 32 about the vehicle vertical direction relative to the base member 34 and thus relative to the frame 12 are rotatable.

In this case, for example, a protective element 40 provided, which in the present case is designed as a protective sleeve. By means of this protective element 40 For example, the guide element 38 protected against excessive contamination, so that the rotation of the retaining element described above 36 relative to the base element 34 is not affected.

Out 4 it can be seen that the retaining element 36 one as a passage opening 42 having formed opening, wherein the guide element 38 the passage opening 42 penetrates. The holding element 36 is thus on the passage opening 42 with the guide element 38 coupled.

The sidecar 30 also includes very good 4 recognizable arms 44 , which with the holding element 36 are connected. Here are the other wheels 32 rotatable on the arms 44 held, so the wheels 32 over the outriggers 44 with the holding element 36 are coupled. As the retaining element 36 over the guide element 38 with the base element 34 connected are the wheels 32 over the outriggers 44 , the retaining element 36 and the guide element 38 with the base element 34 coupled. Furthermore, since the retaining element 36 relative to the base element 34 is movable, in particular rotatable, are, relative movements between the other wheels 32 and the frame 12 admitted in the vehicle vertical direction, these relative movements are sprung and / or damped, for example by means of the spring and / or damping element.

The storage device 28 is, for example, at least indirectly on the retaining element 36 held and thus under the mediation of the holding element 36 with the base element 34 coupled. As a result, for example, moves the electric storage device 28 in the vehicle vertical direction with the sidecar 30 especially with the wheels 32 , relative to the frame 12 With.

Especially good 5 it can be seen that the electrical storage device 28 in the vehicle vertical direction below the frame 12 is arranged. Further, the electric storage device 28 hanging on the sidecar 30 , in particular on the holding element 36 , held, so that the storage device 28 in a particularly simple way on the sidecar 30 mounted and from the sidecar 30 can be dismantled.

In addition, a particularly good looking 4 and 5 recognizable protective element 46 provided, which is designed for example as an apron. The electrical storage device 28 is in the vertical direction of the vehicle down at least partially, in particular at least predominantly or completely, by the protective element acting as a protective device 46 covered. As a result, for example, unwanted, direct contacts of objects arranged on the roadway with the electrical storage device 28 be avoided. In other words, protects the protective element 46 the electrical storage device 28 before collisions with objects arranged on the roadway. In order to realize a particularly efficient protection, the protective element has 46 a first subarea 48 on, which is arranged, for example, at least substantially in a plane which is spanned by the vehicle longitudinal direction and the vehicle transverse direction. In the vehicle longitudinal direction to the front closes to the subsection 48 another subarea 50 of the protective element 46 on, with the subarea 50 perpendicular or present oblique to the sub-area 48 and thus to the previously described level. This can be avoided, for example, that, for example, whirled objects directly against the storage device 28 plump.

Furthermore, it is in the commercial vehicle 10 provided that the electrical storage device 28 in the vehicle transverse direction at least partially between the other wheels 32 is arranged, whereby the electrical storage device 28 especially advantageous with the frame 12 or with the commercial vehicle 10 overall can be carried.
