[0001] This invention relates to a connecting axle assembly for connecting multi-point linkages to, in particular, multi-piece vehicle axles. Furthermore, this invention relates to a connection system and a vehicle, particularly a commercial vehicle. Additionally, this invention relates to a method of manufacturing the connecting axle assembly. Background Technology
[0002] Multi-point linkages and multi-piece vehicle axles are known in the prior art. For example, German patent application DE 199 62406A1 discloses a four-point linkage and US patent application US 2019 / 0135101A1 discloses an axle arrangement with an electric motor. Summary of the Invention
[0003] A connecting axle assembly is proposed for connecting multi-point links to, in particular, multi-piece vehicle axles. The connecting axle assembly includes at least one base for absorbing and dissipating forces and / or moments transmitted between the vehicle axle and the multi-point links. The connecting axle assembly includes at least one axle fastening unit for securing the base to the vehicle axle. The connecting axle assembly includes at least one link connection unit intersecting the main extension plane of the base for connecting the base to the multi-point links.
[0004] Preferably, the connecting axle assembly is at least partially constructed as a connecting axle, particularly as an axle axle. The multi-point linkage is particularly constructed as a three-point or four-point linkage, wherein the four-point linkage is particularly configured for stabilizing commercial vehicles. Alternatively, it is conceivable that the multi-point linkage be constructed as a spread triangular linkage. The spread triangular linkage may particularly have two V-shaped diagonal struts, particularly similar to a three-point linkage, with the diagonal struts having a virtual intersection point. The spread triangular linkage is particularly constructed without a central housing. Preferably, the same vehicle axle can be used according to designs of connecting axle assemblies with different chassis geometries, particularly with different multi-point linkages. The vehicle axle is preferably constructed as a motorized axle, comprising at least one drive unit. The vehicle axle particularly has at least two, preferably at least three, axle section bodies particularly interconnected. Alternatively, the vehicle axle may also have a single axle section body. The "principal extension plane" of an object should be understood in particular as a plane parallel to the largest side of the smallest imaginary cuboid that just completely encloses the object, and that plane passes through the center point of the cuboid.
[0005] Multi-point linkages are preferably configured to connect the vehicle axle to the vehicle frame, particularly for commercial vehicles. Specifically, multi-point linkages are configured to transmit forces acting on the vehicle, particularly the vehicle axle, during operation to the vehicle frame to guide the axle. Multi-point linkages, particularly four-point linkages, are specifically configured to at least partially absorb moments, for example, caused by roll motion, to stabilize the vehicle. These forces and / or moments can be transmitted at least partially from the vehicle axle to the vehicle frame via the multi-point linkage. If the multi-point linkage is directly and centrally connected to the vehicle axle, particularly to the central portion of the vehicle axle, these forces and / or moments may damage the vehicle axle, particularly the central portion. Specifically, for example, due to embodiments accommodating the drive unit, this central portion can be constructed to be less rigid, and particularly softer, than the rest of the axle body.
[0006] The connecting axle device is preferably configured to indirectly connect the multi-point link to the vehicle axle. Specifically, the connecting axle device serves as a connector between the multi-point link and the vehicle axle. Preferably, the connecting axle device is configured to connect the multi-point link to at least one axle section body constructed differently from the central portion. Preferably, the connecting axle device is configured to connect the multi-point link to at least two axle section bodies constructed differently from the central portion. Preferably, the connecting axle device is configured to at least partially absorb the forces and / or moments transmitted between the vehicle axle and the multi-point link and to at least partially export these forces and / or moments from the central portion to at least one axle section body specifically designed differently from the central portion. "Setting up" should be specifically understood as specially programmed, specially equipped, and / or specially designed. For a functional setting object, it should be specifically understood that the object performs the function in at least one operating state.
[0007] Preferably, the connecting axle assembly includes at least two axle fastening units for fastening the base body to the vehicle axle, particularly to at least two axle body sections designed to be different from the central section. Preferably, the connecting axle assembly includes at least one link connection unit for connecting the base body to a multi-point link configured as a three-point link. The base body is preferably constructed as a metal component, particularly a cast component. Alternatively, it is conceivable that the base body be constructed as a composite material component, a forged component, or other components deemed meaningful by those skilled in the art. In particular, the base body has higher component stiffness than the central section of the vehicle axle.
[0008] The axle fastening unit and / or the at least one connecting rod unit are preferably formed as a single piece with the base. "Single piece" should be understood specifically as forming a single component. Preferably, this single component is made from a single blank, block, and / or casting. In particular, the connecting axle assembly is constructed as a single-piece component, specifically for achieving high component stiffness. The axle fastening unit and / or the at least one connecting rod unit specifically includes at least one fastening channel, preferably at least two or more fastening channels, for receiving fasteners such as screws or bolts. In particular, the fastening channels extend at least partially, preferably completely, through the base, and are specifically defined by the base. Preferably, at least one fastening channel of the connecting rod unit configured for connection with a three-point connecting rod extends perpendicularly to at least one fastening channel of the connecting rod unit configured for connection with a four-point connecting rod.
[0009] Preferably, the at least one linkage unit is arranged at least partially in the main extension plane of the base, particularly for effectively absorbing forces and / or torques through the base. Preferably, the at least one linkage unit extends at least partially on opposite sides of the main extension plane of the base.
[0010] According to the design of the present invention, the connecting axle assembly advantageously achieves efficient absorption and / or torque absorption and output of forces and / or torques by means of multi-point linkages. Advantageously, it enables unloading of, in particular, multi-piece vehicle axles and reduces wear. Advantageously, the multi-point linkage can be used with multi-piece, particularly motorized, vehicle axles. Advantageously, it achieves high vehicle occupant safety.
[0011] Furthermore, it is proposed that the connecting bridge device includes at least two linkage connection units for connecting the base body to at least two connection units of a multi-point linkage. Preferably, the connecting bridge device includes at least two linkage connection units for connecting the base body to a multi-point linkage constructed as a four-point linkage or a spread triangular linkage. In particular, the connection units of the multi-point linkage are designed as connecting clamps, especially molecular hinges. Preferably, the linkage connection units for connecting to the four-point linkage or the spread triangular linkage are arranged in two particularly outer regions of the connecting bridge device, and in particular, at least one linkage connection unit is arranged in each outer region. In particular, the outer regions form extreme points that are opposite to each other along the main extension direction of the connecting bridge device. The "main extension direction" of the object should be understood in particular as the direction extending parallel to the longest side of the smallest imaginary cuboid that just completely surrounds the object. Preferably, the axle fastening units are arranged in the outer areas, and in particular, at least one axle fastening unit is arranged in each outer area. Advantageously, reliable connection with four-point linkages or spread triangular linkages can be achieved.
[0012] It is also proposed that the base extends further perpendicularly to the main extension plane than the at least one link connection unit in the central region away from the at least one axle fastening unit.

In particular, the base extends further perpendicularly to the main extension plane than the at least one link connection unit in the central region on at least one side of the main extension plane, preferably on both sides. Advantageously, a particularly robust connecting axle assembly can be prepared.
[0013] Furthermore, it is proposed that the substrate has a maximum lateral extension perpendicular to the main extension plane in the central region, particularly in the aforementioned central region away from the at least one axle fastening unit. Specifically, the substrate has a greater lateral extension perpendicular to the main extension plane in the central region than in the outer region, particularly in terms of component thickness. In particular, the substrate of the connecting axle device, at least configured as a four-point linkage, has a maximum lateral extension perpendicular to the main extension plane in the central region. Preferably, the substrate may have at least one recess, etc., parallel to the main extension plane in the central region, particularly for precise contact with vehicle axles containing, for example, power electronics. Advantageously, effective absorption of forces and / or torques can be achieved through the substrate.
[0014] Furthermore, it is proposed that the base is at least partially constructed as a hollow profile member. Preferably, the base is constructed as a hollow profile member open on one or more sides. In particular, the base of the connecting bridge device configured as a four-point link is designed as a hollow profile member open on one side. In particular, the base of the connecting bridge device configured as a three-point link is designed as a hollow profile member open on multiple sides, especially on both sides. Preferably, the base of the connecting bridge device configured as a four-point link is at least partially open on the side intersecting the main extension plane. In particular, the base of the connecting bridge device configured as a four-point link is at least partially open on the side away from the link connection unit. In particular, the base of the connecting bridge device configured as a three-point link is open on at least one side, preferably both sides, where it does not intersect the main extension plane. Preferably, the base of the connecting bridge device configured as a three-point link is open on both sides arranged on different sides of the main extension plane. Preferably, the base is open at least in the central region. Advantageously, a weight-optimized connecting bridge device can be provided.
[0015] Furthermore, it is proposed that the base has at least one reinforcing rib. Specifically, the base of a connecting bridge device configured to connect at least four-point linkages has at least one reinforcing rib. More specifically, the base has at least one reinforcing rib, preferably at least two reinforcing ribs, particularly preferably at least three reinforcing ribs, and very particularly preferably at least four reinforcing ribs. Preferably, the reinforcing rib has a plane intersecting with the main extension plane. Specifically, the reinforcing rib extends perpendicular to and parallel to the main extension plane. Specifically, the reinforcing ribs support the outer cover regions (Mantelbereich) of the base that are spaced apart from each other transversely to the main extension plane. The base with reinforcing ribs is particularly formed by a cast structure that is particularly open on one side in the central region. Advantageously, a connecting bridge device optimized for weight and stiffness can be provided.
[0016] It is also proposed that the matrix has at least two reinforcing ribs that together form an undercut. Preferably, these two reinforcing ribs at least partially define a central cavity in the central region. Viewed in the main extension plane, these two reinforcing ribs are particularly positioned at an angle of at least 45°, preferably at least 65°, and particularly preferably at least 85° relative to each other. Viewed in the main extension plane, these two reinforcing ribs are particularly positioned at an angle of at most 125°, preferably at most 105°, and particularly preferably at most 85° relative to each other.

[0017] Furthermore, a connection system is proposed, comprising, particularly as described above, at least one vehicle axle of a multi-piece type and at least one connecting axle device according to the invention, for connecting multi-point linkages to the multi-piece vehicle axle. The vehicle axle has at least one connecting unit arranged separately from the central portion of the vehicle axle, as described above, for fastening the connecting axle device. The at least one connecting unit is particularly arranged on the at least one axle section body designed to be different from the central portion. Preferably, the vehicle axle comprises at least two connecting units, wherein, particularly, each at least one connecting unit is arranged on each at least one axle section body designed to be different from the central portion. Preferably, the axle section bodies designed to be different from the central portion, particularly the connecting units, are arranged symmetrically along the vehicle axle about the central portion. Preferably, the connecting units are configured to engage with the axle fastening unit of the connecting axle device. In particular, the connecting units form a helical position for helically securing the connecting axle device to the axle section body designed to be different from the central portion. Advantageously, reliable and low-wear fastening of the connecting axle device on the vehicle axle can be achieved.
[0018] Furthermore, it is proposed that the vehicle axle is constructed as a motorized axle, and the central portion includes at least one drive unit. Specifically, the axle is configured to drive the vehicle wheels connected to the axle in a particularly rotary manner. The central portion at least partially forms a drive housing for accommodating the at least one drive unit. Specifically, the drive unit includes at least one electric motor, preferably at least two electric motors. Alternatively or additionally, it is conceivable that the drive unit includes at least one hydraulic actuator, at least one pneumatic actuator, at least one internal combustion engine, or another actuator deemed meaningful by those skilled in the art.

The axle section bodies constructed differently from the central portion at least partially form a housing for a torque transmission unit. Preferably, the axle section bodies constructed differently from the central portion are designed similarly to each other. Advantageously, the motorized axle can be utilized more reliably and with less wear by means of multi-point linkages.
[0019] Furthermore, it is proposed that the connection system includes at least one multi-point link, particularly a three-point link or a four-point link. As an alternative to the three-point or four-point link implementation, the multi-point link can also be constructed as a spread-out triangular link. The multi-point link is preferably hinged to the vehicle frame at two points. A multi-point link constructed as a three-point link is particularly hinged to the connecting bridge assembly at the other point. A multi-point link constructed as a four-point link is particularly hinged to the connecting bridge assembly at the other two points. Advantageously, this provides an efficient and reliable connection system.
