Embodiment Construction

[0026] figure 1 Designated at 10 is a design of a starter relay for a starter of an internal combustion engine in a motor vehicle. The starter relay 10 has a relay coil 11 on a coil carrier 12 made of plastic, which is fastened to a pole core 13 . In this case, the relay coil 11 is accommodated in a metal housing 14 in which a pole core 13 is accommodated in its open front end. On the bottom of the housing 14 , an armature 15 of the relay, which sinks into the relay coil 11 , is guided axially in a bore. A push rod 16 is fixed in the central hole of the armature 15, the top end of which has a so-called paddle 17 to accommodate a meshing rod for a not shown starter pinion. In the through-opening of the pole core 13 , an actuating rod 18 is guided by means of an insulating sleeve 19 , wherein the front end of the actuating rod 18 is arranged at a distance from the end of the push rod 16 . On the rear end of the operating rod 18 is accommodated axially displaceably a contact b...

Abstract

The invention relates to an engaging relay (10) for starters of internal combustion engines in which a starter pinion engages into a gear rim of the internal combustion engine by applying current to a relay winding (11) and is then driven at full power by the starter motor. The engaging relay is designed with a change-over contact (20) which connects the starter motor to the electricity supply via a resistance element (26) in the first section of the engaging path in order for the starter to rotate slowly and connects the starter motor directly to the electricity supply at the end of the engaging path. In order to independently optimize the dynamics of the engaging relay (10) while simultaneously having the starter motor rotate at a slow speed, the resistance element (26) is arranged around the longitudinal axis (x) of the relay (10) as a largely electromagnetically neutral winding that has two parallel conductors (27a, 27b), the ends of which are interconnected.

Description

technical field [0001] The invention relates to a starter relay for a starter of an internal combustion engine according to the preamble of claim 1 . Background technique [0002] Such starter relays usually have a pull-in coil and a hold-in coil. According to DE 10 2004 032 373 A1, firstly by energizing the two coils, the starter pinion is brought into engagement in the ring gear of the internal combustion engine in an axially displaceable manner while being simultaneously rotated slowly by the starter motor. At the end of the pull-in stroke, the relay armature then actuates a changeover contact, via which the pull-in coil is de-energized and the starter motor is directly connected to the power supply. [0003] A disadvantage here is that the dynamic behavior of the starter relay when the starter pinion is engaged is simultaneously influenced by the relay holding coil. This can create meshing problems with the starter pinion due to too little rotation of the pinion when p...
