Problems solved by technology

As a result, the meshing process and the switching-on process of the motor mains current take place in two separate operating processes, but the structure of the starter relay is mechanically and electrically complex and susceptible to interference

Embodiment Construction

[0017] figure 1 The mechanical structure of the starter 10 for an internal combustion engine of the present invention implemented as a push-type helical gear starter is schematically shown. The starter 10 has a starter motor 12, and the output shaft 14 of the starter motor has a steep thread 16 that cooperates with a corresponding internal thread in the transmission cylinder 18. Alternatively, the output shaft 14 may be driven by a planetary gear transmission device connected in the middle, not shown. The transmission cylinder 18 is fixedly connected to the outer ring of the free rolling ring 20, and the inner ring of the free rolling ring is provided with a pinion 22. The pinion 22 and the free wheel 20 are supported on the output shaft 14 and can move in the axial direction up to a stop 24. Here, the pinion 22 is meshed into a ring gear 26 of an internal combustion engine, not shown. The axial movement is achieved by the relay device 28 shown in detail in the following figu...

Abstract

The invention relates to a starter (10) for an internal combustion engine, comprising a starter motor (12) which can be coupled to the internal combustion engine by means of a pinion (22), and a device for engaging the pinion (22) in a gear rim (26) of the internal combustion engine and connecting the starter motor (12) to a DC voltage supply system (30, 31). In order to disconnect the sequence of operations, the device has separate means, in particular separate relays (57, 64; 60), for engaging the pinion (22) on one hand and turning on the starter motor on the other when the internal combustion engine is started, thus preventing reactions of the engagement dynamics on the contact system when the motor current is switched.

Description

Technical field [0001] The invention relates to a starter for an internal combustion engine according to the preamble of the independent claim. Background technique [0002] On page 986 of the 25th edition of the Bosch Automotive Engineering Manual, a starter of this type implemented as a push-type helical gear starter (Schub-Schubtrieb-Starter) is described through a so-called starter relay. Powered up. The relay assumes the functions of engaging the pinion of the starter motor, that is to say meshing into the ring gear of the internal combustion engine, and switching on the main current of the starter motor. When the pinion gear meshes into the ring gear, two possible processes need to be distinguished here: in about 20%-30% of the turn-on, the teeth of the pinion gear enter the tooth groove of the ring gear, and at about 70%-80% % Is turned on, the teeth of the pinion gear hit the teeth of the gear ring during meshing and the meshing needs to be assisted by the meshing sprin...
