Description

Technical Field

[0001] This invention relates to an axle arrangement structure for a vehicle and a vehicle. Background Technology

[0002] Axle arrangements for vehicles with multiple interconnected components are known from existing technology. For example, multi-link rear axles are known to have various attachment points on the wheel carrier for springs, dampers, and different links, such as lateral and longitudinal links. From the wheel carrier, the springs and dampers typically extend vertically upwards. These components often thus conflict with the geometry of the vehicle structure, such as the body. These components may also sometimes extend significantly into the vehicle's interior space, often restricting space supply, particularly in the rear seat area. This problem is exacerbated, especially in modern vehicles that often feature air suspension, due to the typically large size of the air spring elements. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide an axle arrangement structure for a vehicle that allows for optimized use of the mounting space in the axle area, and especially more mounting space above the axle area.

[0004] This task is accomplished by the features of independent claim 1. The dependent claims contain preferred modifications of the invention.

[0005] This task is therefore achieved through a vehicle axle arrangement comprising a wheel carrier, multiple links, springs and / or damping elements, and a stabilizer. The wheel carrier has an axle, around which a wheel, in particular, can be fixed. The multiple links are connected to the wheel carrier. The wheel carrier may preferably be attached to the vehicle body and / or the vehicle's, for example, a spring-supported axle, solely via links and springs and / or damping elements. The springs and / or damping elements are directly connected to the wheel carrier and / or one of the multiple links at a first attachment point. This first attachment point is positioned rearward of the axle with respect to the vehicle's direction of travel and below the axle in the vertical direction. The stabilizer is also positioned rearward of the axle with respect to the direction of travel. The multiple links include an upper link, which is directly connected to the wheel carrier at an upper attachment point. The upper attachment point is positioned above the axle. Furthermore, the upper link extends rearward at an angle from the wheel carrier with respect to the direction of travel.

[0006] In other words, an axle arrangement structure is provided, particularly a multi-link axle, wherein the wheel carrier can preferably be attached to the vehicle body and / or axle frame only via links and springs and / or damping elements. A first attachment point (which particularly forms a mechanical connection between the spring and / or damping element on the wheel carrier and / or on one of the links) is here arranged behind the axle and vertically below it. Furthermore, a stabilizer is arranged behind the axle. In particular, the stabilizer can be arranged entirely behind the axle. Alternatively, preferably, at least one stabilizer bar back is arranged behind the axle, which forms a lateral connection between the two vehicle sides, for example, at one axle of the vehicle. Furthermore, the upper attachment point of the upper link is arranged above the axle, wherein the upper link extends obliquely rearward within the vehicle.

[0007] The axle arrangement offers the following advantages: it achieves a particularly advantageous utilization of mounting space in terms of the vehicle body and interior space of the vehicle on which it can be installed. Because the first attachment point of the spring and / or damping element on the wheel carrier is significantly shifted downward and rearward, the corresponding attachment point, for example, on the other end of the spring and / or damping element, on the side of the vehicle body, can also be moved rearward and downward. This allows for a larger passenger compartment, particularly rearward and downward, in the vehicle on which the axle arrangement can be installed. In particular, increased space supply can be provided in the area above and forward of the wheel carrier. This increased space supply in the area above and forward of the wheel carrier, facing the passenger compartment, is particularly reliable here through the inclined rearward-extending upper link and the stabilizer bar arranged behind the axle. Furthermore, the special arrangement of the components of the axle arrangement allows for an improved space supply for arranging additional links in the area of ​​the wheel carrier.

[0008] Preferably, the axle arrangement further includes an upper lateral link, which is arranged vertically above the axle. In particular, the upper lateral link is arranged substantially parallel to the axle. Preferably, an upper attachment point is directly connected to the wheel carrier at the upper attachment point, and preferably, the upper attachment point is located substantially at the height of the axle with respect to the direction of travel.

[0009] Particularly preferably, the spring and / or damping element extends vertically between the upper longitudinal link and the upper transverse link. In other words, the spring and / or damping element is located, particularly with respect to the direction of travel, between the upper longitudinal link and the upper transverse link. This allows the components to be optimally arranged in the upper region of the axle arrangement in a particularly simple manner, thereby providing an increased supply of mounting space toward the vehicle interior.

[0010] Preferably, the upper longitudinal link and the upper transverse link are constructed together as a triangular link, particularly as a single unit. Preferably, this triangular link can be arranged in the upper region of the axle arrangement. In particular, the triangular link is connected to the wheel carrier above the axle at the upper attachment point. By combining the upper longitudinal link and the upper transverse link into a triangular link, a particularly simple, low-cost, and lightweight construction can be provided, which also occupies very little space in the wheel carrier region.

[0011] Preferably, the axle arrangement further includes a swing-type support through which the stabilizer is connected to the wheel frame. Therefore, the stabilizer is indirectly connected to the wheel frame via the swing-type support. Preferably, the swing-type support extends substantially in the vertical direction.

[0012] Preferably, the pendulum support is directly connected to the wheel frame at the stabilizer attachment point, particularly where the stabilizer attachment point is located below the wheel axle. This optimizes the use of existing installation space and / or provides more installation space for other components.

[0013] Preferably, the plurality of links include camber links that are directly connected to the wheel carrier at a second attachment point. This second attachment point is located behind the axle in the direction of travel and below the axle in the vertical direction. This means that the second attachment point for the camber link, like the first attachment point, is located vertically below the axle and behind the axle in the direction of travel. This allows for a particularly advantageous arrangement of the links in the axle arrangement, providing significantly more free space for the vehicle body and / or passenger compartment in the vertically upper part of the axle arrangement and in the forward direction of travel.

[0014] Preferably, the first attachment point is arranged vertically below the second attachment point. This allows the spring and / or damping elements to be attached particularly deeply to the wheel carrier. In addition to the particularly advantageous geometry regarding the increased mounting space provided in the vertical upper region above the axle arrangement structure, this also provides optimal kinematics for the vehicle's suspension and damping to offer high driving comfort for the occupants.

[0015] Particularly preferably, the camber link has a through opening through which a spring and / or damping element extends.

[0016] Preferably, the camber link may have two legs, which are specifically constructed as a single integral component, forming a through opening between them. This allows for optimal utilization of the mounting space of the axle arrangement, particularly in the lower region of the wheel carrier. In particular, this allows the first and second attachment points to be close to each other, where the through opening, preferably of a corresponding size, provides a large range of motion for both the spring and / or damping elements and the camber link. Furthermore, by bringing the attachment points on the wheel carrier close to each other, a smaller, space-saving geometry of the wheel carrier can be allowed, for example.

[0017] More preferably, the plurality of links includes longitudinal links that are directly connected to the wheel frame at a third attachment point. The third attachment point is arranged vertically below the axle. This advantageously avoids components of the axle arrangement extending significantly upwards or forwards toward the passenger compartment.

[0018] Preferably, the third attachment point is arranged vertically below the first and second attachment points. In particular, the third attachment point can thus form the lowermost attachment point on the wheel carrier. Alternatively, preferably, the third attachment point is arranged vertically between the first and second attachment points. Alternatively, preferably, the third attachment point is arranged vertically above the first and second attachment points. This means that the third attachment point can form the uppermost of the three attachment points on the wheel carrier.

[0019] Particularly preferably, the spring and / or damping element comprises a damper and a spring. The damper is preferably directly connected to the wheel carrier at the first attachment point. Preferably, the spring is also directly connected to the wheel carrier at the first attachment point. In particular, the spring and damper thus form a common spring support. Alternatively, preferably, the spring is indirectly connected to the wheel carrier at the spring attachment point. In this case, the spring and damper are arranged particularly independently of each other. Preferably, the spring attachment point can be arranged on the camber link.

[0020] Preferably, the plurality of links comprises a total of five links. Therefore, in particular, the axle arrangement is a five-link axle. Specifically, two links, for example, constructed together as a common triangular link, are also considered as two "links".

[0021] Furthermore, the present invention relates to a vehicle, particularly a motor vehicle, especially a passenger car, which includes the described axle arrangement structure. Attached Figure Description

[0022] Further details, features, and advantages of the invention will become apparent from the following description and accompanying drawings. In the drawings: Figure 1A simplified schematic diagram of a vehicle having an axle arrangement structure according to a preferred embodiment of the present invention is shown. Figure 2 Show Figure 1 Side view of the axle arrangement structure. Figure 3 Show Figure 1 Another side view of the axle arrangement structure. Figure 4 Show Figure 1 A perspective view of the axle layout structure. Figure 5 Show Figure 1 Perspective detail of the axle layout structure, and Figure 6 Show Figure 1 Another detailed perspective view of the axle arrangement structure. Detailed Implementation

[0023] The preferred embodiment of the axle arrangement structure 1 of the vehicle 100 is described below. Referring here... Figures 1 to 6 Components that are identical or have the same function are always given the same reference numerals.

[0024] Figure 1 A simplified schematic perspective view of vehicle 100 is shown. Vehicle 100 is a motor vehicle, particularly a passenger car.

[0025] The vehicle 100 includes an axle arrangement structure 1 according to the invention on each side of its rear axle 20 located at the rear along the direction of travel. Preferably, each axle arrangement structure 1 is constructed and arranged symmetrically about the longitudinal axis of the vehicle 100.

[0026] Details of the axle arrangement structure 1 according to the present invention are as follows: Figures 2 to 6 It is shown in the figure and described below.

[0027] The axle arrangement structure 1 is a multi-link rear axle, which has multiple links 3, specifically five links 31, 32, 33, 34, and 35.

[0028] In addition, part of the axle arrangement structure 1 is a wheel frame 2, which is configured to connect to the wheels 105 of the vehicle 100.

[0029] In addition, the axle arrangement structure 1 includes a spring and / or damping element 4, which has a damper 41 and a spring 42.

[0030] In the illustrated embodiment, the damper 41 and spring 42 are integrated into a single component, which may also be referred to as a spring strut, for example. In an alternative (not shown) embodiment, the spring and / or damping element 4 may also be separate, i.e., the damper 41 and spring 42 may be arranged as separate components at different locations.

[0031] The wheel carrier 2 of the axle arrangement structure 1 is attached to the body 50 of the vehicle 100 only via connecting rods 3 and springs and / or damping elements 4. This means that, in particular, there is no direct mechanical fixed connection between the wheel carrier 2 and the body 50.

[0032] The arrangement and construction of the components of the axle arrangement structure 1 are specially designed to provide the largest possible space in the area facing the passenger compartment of the vehicle 100, that is, in the area in front of the axle arrangement structure 1 in the direction of travel 101 and above it in the vertical direction 102. In particular, this allows for more installation space on the body 50 in the area of ​​the rear seats of the vehicle 100. This provides greater comfort for the occupants of the vehicle 100. In particular, it also allows for greater freedom in the flexible seating configuration of the seats in the vehicle 100.

[0033] This is achieved through the design of the axle arrangement structure 1 according to the present invention, as described below.

[0034] Multiple links 3 and springs and / or damping elements 4 are directly connected to the wheel frame 2 via individual attachment points. Preferably, the attachments are hinged, i.e., allowing rotation about a respective axis. Preferably, all these axes of rotation are arranged substantially horizontally.

[0035] In the axle arrangement structure 1, the spring and / or damping element 4 is connected to the wheel frame 2 at the first attachment point 11, wherein the first attachment point 11 is arranged behind the wheel axle 20 with respect to the travel direction 101 and below the wheel axle 20 in the vertical direction 102.

[0036] Thus, the spring and / or damping element 4 can be attached to the wheel frame 2 as deeply as possible, thereby facing upward toward the required installation space of the passenger compartment, and especially when viewed from the wheel axle 20, it can be kept particularly small.

[0037] In addition, the axle arrangement structure 1 includes an upper longitudinal link 33 and an upper transverse link 34. The upper longitudinal link 33 and the upper transverse link 34 together form a triangular link 36.

[0038] The lateral connecting rod 36 is directly connected to the wheel frame 2 at the upper attachment point 14, wherein the upper attachment point 14 is located above the wheel axle 20 (see...). Figures 2 to 4In particular, the upper attachment point 14 is located at approximately the height of the wheel axle 20 with respect to the direction of travel 101.

[0039] The upper transverse link 34 extends substantially parallel to the wheel axle 20.

[0040] The upper longitudinal link 33 extends rearward from the upper attachment point 14, particularly in the horizontal plane, with respect to the direction of travel 101.

[0041] The spring and / or damping element 4 is substantially vertically upward and extends between the upper transverse link 34 and the upper longitudinal link 33.

[0042] Furthermore, the plurality of links 3 include a lower longitudinal link 32, which is directly connected to the wheel frame 2 at a third attachment point 13. The third attachment point 13 is arranged vertically below the wheel axle 20.

[0043] In detail, the third attachment point 13 is arranged vertically 102 below the first attachment point 11 (see especially). Figure 2 and Figures 4 to 6 ).

[0044] The lower longitudinal link 32 extends forward at an angle relative to the direction of travel 101.

[0045] Furthermore, the axle arrangement structure 1 may include a central transverse link 35, which is arranged substantially at the height of the axle 20 in the vertical direction 102 and directly connected to the wheel carrier 2. The central transverse link 35 may be arranged behind the axle 20 in the travel direction 101 (see, in particular...). Figure 3 Furthermore, the intermediate lateral link 35 extends substantially laterally to the direction of travel 101.

[0046] The axle arrangement structure 1 also includes a stabilizer 6. The stabilizer 6 is positioned completely behind the axle 20 with respect to the direction of travel 101.

[0047] The stabilizer 6 is attached to the wheel frame 2 by means of the pendulum support 7.

[0048] The pendulum support 7 is directly connected to the wheel frame 2 at the stabilizer attachment point 17, and extends substantially vertically upward from the stabilizer attachment point 17 (see...). Figures 2 to 4 ).

[0049] The stabilizer attachment point 17 can be arranged vertically 102 below the axle 20.

[0050] In particular, the stabilizer 6 is positioned almost entirely above the wheel axle 20.

[0051] Furthermore, the plurality of links 3 include a camber link 31, which is directly connected to the wheel carrier 2 at a second attachment point 12. The second attachment point 12 is located behind the axle 20 with respect to the direction of travel 101 and below the axle 20 in the vertical direction 102 (see [reference]). Figure 2 and Figure 5 ).

[0052] The camber link 31 extends substantially parallel to the axle 20 or at a slight angle to the rear (see...) Figure 2 and Figure 3 ).

[0053] The second attachment point 12 is located vertically above the first attachment point 11, that is, between the first attachment point 11 and the axle 20.

[0054] The camber link 31 has a through opening 21 through which the spring and / or damping element 4 extends in the vertical direction (see especially...). Figure 6 ).

[0055] In detail, the camber link 31 has two legs 31a, with a through opening 21 formed between the two legs, and the two legs are constructed as a single integral component. In particular, the size of the through opening 21 is designed to allow sufficient degrees of freedom of movement for the spring and / or damping element 4 and the camber link 31 in all possible cross movements of the axle arrangement structure 1.
