Advantageous embodiments can be taken from the dependent claims and the description.The invention relates to a composite of a belt arrangement and a battery arrangement for a motor vehicle, comprising the battery arrangement, wherein the battery arrangement comprises at least a first and a second battery, wherein the belt arrangement comprises a plurality of belt elements, wherein each belt element comprises at least three half shells, wherein a first half shell and a second half shell are arranged on a first axis, wherein a third half shell is arranged spaced apart from the first two half shells on a second axis, wherein the second axis is arranged parallel but offset to the first axis, and wherein a first battery is held by the first half shell and the second half shell, and wherein a second battery is held by the third half shell, wherein each battery is held by at least two belt elements.An exception can be formed by the first battery and the second battery, which is held only by a strap element. This may be due to the position at the edge of a battery housing, for example.In a development, the first and the second half shell are spaced apart on the first axis by a spacing space such that the third half shell is arranged between the first and the second half shell.In a development, the spacing space has a width which corresponds approximately to the width of the third half shell.In a development, each half shell comprises a first and a second end which are directed towards one another, wherein the distance between the first end and the second end is smaller than the diameter of the respective battery. As a result, a form-fitting or force-transmitting connection can be produced alternatively or additionally, the respective battery is fixed in the respective half shell by means of an adhesive bond.In a development, the respective half shell is of spring-elastic design, wherein the respective battery is clamped in the respective half shell.In a development, the first half shell and the second half shell are pivotably connected to the third half shell.In an advantageous development, the respective half shells are connected to one another at a contact point. The connection can be rigid or movable. The connection can be formed by a metal pin.In a advantageous development, the half-shells or the respective half-shell can comprise coupling points for a cooling medium. The half shells can be produced, for example, under 3D pressure and can be connected to one another by cooling channels.In a further development, each belt element is formed in one part or in multiple parts.In an advantageous development, an insert can be cast or inserted into at least one of the half shells.In a development, each belt element consists of a plastic or comprises a plastic or the belt element consists of a metal or a metal alloy or comprises such or comprises such or consists of or comprises a mineral material or comprises such.An example of a mineral material is mica. Mica, also known as mica, is a group of silicate minerals that are distinguished by their particular physical and chemical properties. These minerals are distinguished by their layer-like structure, which makes it possible to split them into thin platelets. This property gives them high splittability and flexibility.A remarkable feature of mica is its thermal stability. It can withstand high temperatures and is therefore frequently used in applications where heat resistance is required. In addition, mica has excellent electrical insulating properties, making it a valuable material in the electronics and electrical industry.Mica also has good chemical resistance to many acids and bases, which is particularly advantageous in batteries, and low water absorption capacity. This makes it resistant to corrosion and moisture.In a development, each battery is held by a first number of half shells of a first belt element and by a second number of half shells of a second belt element, wherein the first number of half shells is different from the second number of half shells.In an advantageous development, each battery is held by two half shells of a first belt element and one half shell of a second belt element.The invention also relates to a motor vehicle having the combination of the belt arrangement and the battery arrangement according to at least one of the preceding developments.The invention is described below purely by way of example with reference to the drawings.
