Abstract: A battery arrangement for a motor vehicle includes a battery housing and a cell module that is disposed on a base plate of the battery housing. The cell module has a cell module housing and a plurality of battery cells disposed in the cell module housing and a base of the cell module housing is connected to the base plate of the battery housing by an adhesive compound. The cell module housing is connected to a side wall of the battery housing by an adhesive and the adhesive has a higher shearing resistance than the adhesive compound disposed between a base of the cell module housing and the base plate of the battery housing.

Abstract: The invention relates to a tool combination consisting of a chisel holder, which can be fastened to a milling drum of a soil tillage machine, and at least one leading and one trailing chisel, which are retained on the chisel holder, wherein the trailing chisel is arranged after the leading chisel, based on a working movement of the tool combination in use in the soil tillage machine, and wherein each chisel has a chisel tip having a cutter. According to the invention the trailing chisel tip of the trailing chisel has, at least in some areas, a greater hardness than the leading chisel tip of the leading chisel. Thus stoppage times of the soil tillage machine for maintenance can be reduced and the loss of chisels can at least be decreased.

Abstract: The invention relates to an interchangeable chisel holder (40) which can be fixed to a milling drum (15) of a ground-working machine (10), having a forward chisel holder (42) for the interchangeable holding of a forward chisel (20), preferably a round-shaft chisel, and having a rearward chisel (30, 31), which is held on the interchangeable chisel holder (40), wherein, as based on a working movement (76) of the interchangeable chisel holder (40) when used in the ground-working machine (10), the rearward chisel (30, 31) is arranged behind the forward chisel holder (42). In such an interchangeable candleholder (40) provision can be made, according to the invention, for the rearward chisel (30, 31) to be held on the interchangeable chisel holder (40) axially and fixed in the circumferential direction of the chisel holder. Maintenance-induced stoppages of the ground-working machine can thus be reduced and the loss of chisels can at least be lowered.

Abstract: The invention relates to a bit holder for an earth working machine, in particular a road milling machine, having a support body onto which a holding portion having a bit receptacle, and oppositely an insertion projection, are shaped. The holding portion is terminated at the end by a wear surface, and the bit receptacle by a centering receptacle opening in bevel fashion toward the wear surface.

Abstract: In order to determine the tire positions or wheel positions automatically while the vehicle is in operation, the attenuation along a transmission path from the tire to a fixed position on the vehicle is measured and compared with stored values. Systems of this kind are error prone when other vehicles using similar systems are located in the receiving range. In order to increase the reliability of such a system it is useful to determine the attenuation along the transmission paths between the wheel units and compare it with known values. Toward that end, the novel wheel unit enables data to be provided by way of which the attenuation of the transmission path from one wheel unit to another wheel unit can be determined.

Abstract: In the automotive industry that there is an increasing need for automatic tire pressure checking systems. One challenge here is to identify the positions of the tires on the vehicle. This is normally programmed-in it at the factory at the end of the production line. The tires however mostly do not remain in the same position during their lifetime. The invention allows a wheel unit to be automatically assigned to its wheel position on the motor vehicle. To this end the attenuation along a transmit path from a wheel unit to a transmission unit or receiving unit on the motor vehicle is determined. The attenuation determined is a characteristic value which allows conclusions to be drawn about the position of a wheel unit. An assignment by way of the attenuation has the advantage that the wheel unit is independent of variations in the transmit power of the transmission unit.
