摘要： A coil carrier for an electromagnetic switch of a starting device including a cavity enclosed by a carrier wall for winding of a coil wire. The carrier wall may extend in an axial direction from a first end wall to a second end wall. The coil carrier may include at least one separating body protruding radially, and extending in a circumferential direction, on a side of the carrier wall facing away from the cavity. The at least one separating body may have a recess which separates a first separating body end of the at least one separating body from a second separating body end of the at least one separating body in the circumferential direction. The at least one separating body may have an axially extending body width that decreases along the circumferential direction.

摘要： An electromagnetic switch for a starting device of an internal combustion engine may include a coil carrier having a carrier wall enclosing a cavity, a coil winding, a piston, and a ferromagnetic bypass body. During operation, the coil winding may provide a magnetic field within the cavity. The piston may be disposed in a passive position and may be adjusted axially in a direction of a core. The coil winding may have a coil wire which may be wound around the carrier wall in a first winding direction and an opposing second winding direction. The ferromagnetic bypass body may surround the cavity and may be arranged radially between the cavity and the coil winding. In the passive position of the piston, the bypass body may axially overlap the axial gap. At least one winding of the second winding section may axially overlap the bypass body.

摘要： A solenoid drive may include a ferromagnetic housing having a coil receiving chamber axially limited by opposing first and second face side walls, and a cylindrical coil arrangement having at least one electric coil, and being arranged in the coil receiving chamber and coaxially surrounding a cylindrical coil interior space. The solenoid drive may also include a ferromagnetic plunger stop having a central region projecting axially in the coil interior space, and a ferromagnetic plunger arranged at the housing opposing the plunger stop. The plunger may project axially into the coil interior space, and may be adjustable axially bi-directionally between an active position proximal to the central region and a passive position distal to the central region. The solenoid drive may further include a ferromagnetic bypass device arranged coaxially to the coil arrangement, radially within the at least one coil, and spaced apart axially from the face side walls.

The plunger may project axially into the coil interior space and may be adjustable axially bi-directionally relative to the housing between active and distal positions, which are proximal and distal, respectively, with respect to the central region. The bypass device may be spaced apart axially from the face side walls. In the passive position, the plunger may project axially into the bypass device such that an axial overlap between the plunger and the bypass device may be defined.

The coil winding may have a coil wire wound on a side of the carrier wall facing away from the cavity which provides a magnetic field within the cavity. The piston may be axially adjustable in the cavity. The piston may be disposed in a passive position and may be adjusted axially in a direction of a core. In the passive position, the piston and the core may define an axial gap therebetween in the cavity. The coil wire may have a first winding section and a second winding section wound in opposing directions. At least one winding of the second winding section may axially overlap the axial gap.
