AI Technical Summary

Problems solved by technology

However, the uneven profile of the housing surface of the piston results in uneven sliding of the piston within the coil holder
Furthermore, the maximum possible size of the slot is limited, making possible a small reduction in adjustment force

Embodiment Construction

[0036] Such as Figure 1 to Figure 11 The electromagnetic switch 1 shown, hereinafter simply referred to as switch 1, is usually as Figure 11 Components of the starting device 2 of the internal combustion engine 3 shown in the example in . The starter device 2 also has an electrically driven motor 4 or an electric motor 4 . During operation, this electric motor 4 transmits torque to the starting element 6 of the starting device 2, for example via the shaft 5, to the starting element 6 of the starting device 2, wherein the starting element 6 will be used to start all the components of the internal combustion engine 3 The torque is transmitted to the counterpart starting element 7. For torque transmission, a starting element 6 , for example formed as a pinion 8 , and a counter-starting element 7 , for example formed as a ring gear 9 , are arranged in engagement. When the internal combustion engine 3 has been started, the engagement of the starting element 6 with the counter-...

Abstract

The present invention relates to an electromagnetic switch for a starting device of an internal combustion engine, which electromagnetic switch has a coil wire wound to form a coil winding, wherein the coil wire is wound in a first winding direction and partially in a second winding direction which is opposite to the first winding direction. The switch furthermore has a ferromagnetic bypass body which is arranged radially between the coil winding and a cavity of the switch, wherein the bypass body at least partially axially overlaps an axial gap which, in a passive position of a piston of theswitch, is formed between the piston and a core, and wherein at least one winding of the coil wire wound in the second winding direction axially overlaps the bypass body. The invention furthermore relates to a starting device for an internal combustion engine, which starting device has an electromagnetic switch of this type.

Description

technical field [0001] The invention relates to a solenoid switch for a starter, which has a coil carrier on which a coil wire of a coil winding is wound. The invention also relates to a starting device having a switch of the type described. Background technique [0002] In order to start the internal combustion engine, a starter device is usually used. Starting devices of this type generally have a starting element, such as a pinion. To start the internal combustion engine, a starting element is arranged in engagement with a counter-starting element of the internal combustion engine, such as a ring gear, and the counter-starting element is driven to start the internal combustion engine. [0003] A starting device of the type described is known, for example, from DE 10 2009 052 938 A1. The starting device has a solenoid switch with a coil carrier, on which a holding coil and an adjustment coil or a pull-in coil are wound, each of which is wound by a coil wire around the c...
