Definitions
- the invention relates to a fastening arrangement of an auxiliary frame for a vehicle axle on a body of a motor vehicle according to the preamble of claim 1.
- the invention also relates to a motor vehicle with such a fastening arrangement.
- An auxiliary frame for a rear axle is known from DE 10 2016 000 669 B3, which is composed of respective longitudinal members and cross members and adjoins a body structure element of the body of the motor vehicle with one area.
- a traction battery of the electrically operated motor vehicle which is arranged in an underfloor arrangement below the vehicle floor, from damage caused by a rear-end collision in the event of a rear-end collision of the motor vehicle
- at least one of the subframe side members is extended forwards in the longitudinal direction of the vehicle with a subframe-side bearing component , which is connected to a bearing component on the battery housing side with the interposition of a vibration damper.
- the object of the present invention is therefore to create a fastening arrangement of the type mentioned above, by means of which an excessive accident-related movement or displacement of the subframe in the direction of the center of the vehicle can be avoided reliably and by a weight-saving solution.
- the subframe has a support device with at least one support element, which supports the subframe against an accident-related movement towards the center of the vehicle on the structural body element, in particular a cross member, and that the support element is arranged on the upper side of one of the longitudinal members. If, for example, in the event of a rear-end collision, the subframe is displaced forwards in the longitudinal direction of the vehicle as a result of an accident, i.e.
- the support device ensures that the subframe is supported on the body, in particular on a cross member of the body, in order to prevent the forward displacement to reduce the subframe and on the other hand to involve the body of the motor vehicle to absorb the accident forces introduced by the subframe particularly cheap and early.
- load paths that have not previously been used are therefore opened up in order to absorb the accident forces introduced as a result of the displacement or movement of the subframe through the motor vehicle body while absorbing the energy introduced can.
- transverse load paths that would otherwise remain unused in a rear-end crash are included in the crash kinematics.
- the additional weight for these protective measures is only in the additionally provided Support device can be seen and can therefore be kept very small in order to still achieve a very positive effect on the protection to be achieved.
- the supporting device can be supported integrally on the corresponding body structure part, in particular on the corresponding body shell cross member, during the accident scenario. This prevents excessive forward displacement of the subframe of the rear axle and thus protects, for example, the energy store from hard contact with the subframe or components carried by it, such as an electric drive unit or other components of the electric drive train.
- the arrangement according to the invention of the at least one support element on the upper side of one of the side members of the subframe enables early contact to be made with the body crossmember in the event of a crash and thus the desired support of the subframe, for example to protect an electrical energy store arranged in the underbody area of the vehicle.
- a further advantageous embodiment of the invention provides that the at least one support element is arranged at a distance from the structural body element, in particular the cross member. This means that the at least one support element or the support device only comes into contact with the structural body element/cross member during the course of the displacement or movement of the subframe caused by the accident, after which corresponding forces are then transmitted between the subframe and the body via the support device.
- Such an arrangement of the at least one support element has the particular advantage that noises between the subframe and the body can be avoided.
- a support element is arranged on each of the two longitudinal members of the auxiliary frame.
- the load paths on both sides of the vehicle can thus be activated in a particularly favorable manner if an accident-related force is applied to the subframe.
- accident forces introduced unequally into the two longitudinal members of the subframe or displacement movements of the subframe such as those that occur in a collision with a small width overlap of the motor vehicle with an accident partner or an obstacle, can be introduced into the body in an improved way.
- the at least one support element of the support device is designed as an energy absorption element for the targeted absorption of accident energy when supported on the structural body element/cross member. In this way, additional accident energy can be absorbed by means of the supporting device or the respective supporting element.
- a further advantageous embodiment of the invention provides that respective side members of the motor vehicle body are connected to the cross member extending transversely thereto.
- the cross member has support areas adjoining the respectively associated longitudinal member on which the respective laterally associated supporting element is supported in the event of an accident-related movement of the subframe towards the center of the vehicle.
- the at least one support element of the support device is designed as a formed sheet metal part.
- Sheet metal components of this type can be produced particularly inexpensively and are also highly effective in terms of their function. For example, they can also be designed in a simple manner as energy absorption elements and can be easily connected to the subframe in terms of production technology.
- the at least one support element is arranged on a region of the subframe that slopes downward toward the center of the vehicle, in particular on the respective longitudinal member of the subframe.
- a particularly favorable support of the respective support element on the auxiliary frame, in particular on the respective longitudinal member is thus produced.
- this is characterized in that an underfloor energy store is provided for an electric drive of the motor vehicle, to which the subframe for the vehicle axle adjoins, and that in the assembled state between the subframe, in particular a cross member of the subframe, and the energy store there is a distance (A) which is greater than the distance between the at least one support element on the upper side of the side member of the auxiliary frame and the cross member of the body. Because of this configuration, hard contact between the subframe and the electrical energy store can be avoided.
- the fastening arrangement according to the invention can also be used in vehicles with other drives in which an accident-related displacement of the subframe towards the center of the vehicle, in particular an accident-related forward displacement of a rear axle subframe, is avoided should.
- the subframe can be provided not only for the rear axle, but also, for example, in the area of the front-end structure of the motor vehicle as a front axle carrier, engine carrier or integral carrier.
- FIG. 1 shows a plan view of an auxiliary frame of a rear vehicle axle of an electrically driven motor vehicle, components of an electric drive train also being arranged on the auxiliary frame
- Fig. 2 shows a perspective view of a detail of a side view of a motor vehicle body of a passenger car with a rear axle subframe arranged thereon according to FIG support the subframe on the crossmember in the event of an accident-related forward displacement in the direction of the center of the vehicle;
- FIG 3 shows a sectional plan view of the fastening arrangement according to FIG support a forward displacement of the subframe caused by an accident
- FIGS. 1 to 3 shows a fragmentary and sectional perspective view obliquely from behind of the attachment arrangement of the subframe on the motor vehicle body according to FIGS. 1 to 3, the arrangement of one of the two support elements on the associated longitudinal member of the subframe and its position relative to the cross member being visible in particular.
- FIG. 1 shows a top view of an auxiliary frame 10 for a rear vehicle axle 12 of an electrically driven passenger car.
- Such an auxiliary frame 10 is also referred to as a rear axle carrier, integral carrier, axle bolster or the like.
- a rear axle carrier such as a rear axle carrier, integral carrier, axle bolster or the like.
- not only the respective axle members such as links 14 and the like of the rear axle 12 can be seen, but also components 16 of an electric drive train for driving the rear axle 12.
- the auxiliary frame 10 comprises respective longitudinal members 18 which are connected to one another via a front cross member 20 and a rear cross member 22 . Also recognizable are respective bearing elements 24, 26 and additional ones Bearing elements 28, via which the subframe 10 is connected to the motor vehicle body of the passenger car.
- a support element 30 of a support device 32 is arranged on top of each of the two side members 18 of the subframe 10, i.e. on the top side facing away from a roadway recognize is to be described in more detail.
- FIG. 2 shows the fastening arrangement of the auxiliary frame 10 on a rear structure of a motor vehicle body of a passenger car in a partial side view. It can be seen first of all that the subframe 10 with its front end area 34 and components arranged in this end area 34, for example the components 16 of the electric drive train, is connected to a rear end area 36 of an electric energy store 38 fastened in an underfloor arrangement on the underside of the vehicle floor in the form of of a high-voltage storage unit.
- the energy store 38 is arranged here, for example, between the respective side skirts below the passenger compartment of the motor vehicle.
- the rear structure 42 of the passenger vehicle which is shown in Figure 3 in a sectional top view together with the subframe 10 arranged underneath and the associated parts and components of the rear axle 12 or the electronic drive train, has respective rear side members 44, which are located on the inside of respective wheel housings 46 extend for the rear wheels.
- the side members 44 are connected to one another in a front region near the passenger compartment via a front cross member 48 which extends in the vehicle transverse direction (y-direction in the vehicle coordinate system) and approximately horizontally between the side members 44 .
- Another cross member 50 is arranged at a distance in the longitudinal direction of the vehicle (x-direction in the vehicle coordinate system) behind the front cross member 48 and also extends between the two longitudinal members 44.
- the front cross member 48 is formed at least substantially inverted L-shaped in cross section. Furthermore, it is recognizable that the subframe 10 is adjacent to the front cross member 48 with a front upper area 52, which in the present case is essentially formed by the respective longitudinal members 18.
- the two supporting elements 30 of the supporting device 32 are presently arranged in this region 52 of the auxiliary frame 10 or the respective longitudinal member 18 adjoining the cross member 48--as can be seen in particular from FIG.
- the two supporting elements 30 are in lateral cross section—as shown in FIG. 2 recognizable - essentially triangular or ramp-shaped.
- each of the support elements 30 is arranged on a region 54 of the respective longitudinal member 18 of the auxiliary frame 10 which slopes downward towards the center of the vehicle or towards the front.
- the respective support elements 30 run with a respective end face 56 close to a flank 58 of the cross member 48 .
- a small distance is provided between the end face 56 of the respective support element 30 and the flank 58 of the cross member 48 , that is to say, in the present case the support elements 30 are not directly in contact with the cross member 48 .
- the support elements 30 may rest directly against the cross member 48 or for the support elements 30 to also be directly connected to the cross member 48, for example via respective joining connections, mechanical connections or the like.
- the respective support element 30 is arranged in the vertical direction of the vehicle (z-direction in the vehicle coordinate system) at the height of the cross member 48 or its flank 58, which means that the end face 56 of the respective support element 30 is opposite the flank 58 of the cross member 48 is arranged.
- the front end area 34 of the auxiliary frame 10, in particular also its front cross member 20, is arranged opposite the rear end area 36 of the electrical energy store 38 in the assembled state.
- the distance A is so large that in the event of a vehicle collision with an associated, crash-related displacement and/or deformation of the subframe 10 in the direction of the cross member 48, at least one of the support elements 30 arranged on the upper side of the longitudinal member 18 of the subframe 10 on the cross member 48 of the body is supported before the subframe 10 hits the electrical energy store 38 .
- support is understood to mean that the support elements 30 on the auxiliary frame 10 transmit the crash forces into the body via the cross member 48 and also into other body support structures. It remains to be noted that, under certain circumstances, the extent of the crash-related displacement of the auxiliary frame 10 in the direction of the electrical energy store 38 can advantageously be reduced by means of the supporting elements 30 according to the invention. In any case, it is ensured that the crash forces are introduced into the body via the support elements 30 before the auxiliary frame 10 hits the energy store 38, so that the auxiliary frame 10 prevents the energy store 30 from making hard contact.
- FIG. 3 also shows that the longitudinal members 18 of the subframe 10 extend in the region 54 in which the supporting elements 30 are arranged, on the inside of the respective longitudinal member 44 of the rear structure 42 of the motor vehicle body. Accordingly, the support elements 30 are arranged in a respective support area 60 of the cross member 48 which is close to the respective connection to the laterally adjacent longitudinal member 44 of the rear structure 42 .
- Figure 4 shows a detail and perspective sectional view from an angle from behind into the trunk of one of the two support elements 30 of the support device 32 again in its arrangement in the area 54 of the corresponding longitudinal member 18 of the auxiliary frame 10.
- the support element 30 is on the visible on the left side of the vehicle.
- the support elements 30 are designed as formed sheet metal parts and are provided with corresponding openings, beads or the like, so that they can also be used in a targeted manner for energy absorption.
- the support device 32 with the respective support elements 30 is moved towards the center of the vehicle according to an arrow 52, in the present case forwards in the longitudinal direction of the vehicle out, moved forward until the support elements 30 are supported on the cross member 48 as a result of this movement caused by the accident.
- other parts such as components 16 of the electric drive train or other chassis elements are also moved forward in the longitudinal direction of the vehicle, as indicated by arrow 64 .
- the subframe 10 is supported by means of the support device 32 or by means of the respective support elements 30 provided in the present case above the longitudinal members 16 of the auxiliary frame 10.
- This support of the auxiliary frame 10 should on the one hand in the event of an accident-related forward displacement of the auxiliary frame 10 corresponding accident forces via the support elements 30 of the support device 32 into the cross member 48 and from there into the side members 44 of the rear structure 42 or into other load paths, in order to enable targeted support and absorption of impact energy and, on the other hand, to reduce the accident-related forward displacement of the subframe 10 with the vehicle axle 12 and the components 16 of the electronic drive train in such a way that the energy store 38 is not subjected to excessive forces and deformed, particularly in the rear end region 36 .
- the support device 32 provides a simple way of reducing the displacement of the auxiliary frame 10 relative to the energy store 38 and thus avoiding excessive damage to it.
- the support device 32 with the support elements 30 allows an extremely lightweight and simple, but nevertheless highly effective solution. It is clear that the support elements 30 can also be provided elsewhere on the subframe. In addition, this concept can also be used for subframes arranged on a front structure of the motor vehicle body.
