Problems solved by technology

[0038] According to the geometric structure distribution or wear of the various parts of the starter head, the inaccurate positioning of the elastic washer or spring in the free wheel will lead to changes in the contact pressure between the friction surfaces, which will affect the self-locking function of the friction clutch or the starter. Free wheel function of the head

Embodiment Construction

[0070] Referring to Figures 5-8, the same reference numerals are used for the same or similar elements as in Figures 1-4.

[0071] In FIGS. 5-7 , the control rod 25 and the contactor are not shown for simplicity.

[0072] In FIG. 5, the starter head 26 comprises a drive gear 32, a drive 33 adapted to be driven by the fork of the control lever 25 in FIG. A freewheel 34 formed by a friction clutch. The latter is provided with two annular complementary friction surfaces 37 , 40 . These surface shapes are either convex or concave.

[0073] The first friction surface 37 is arranged inside a frustoconical skirt 48 of a connecting piece 45 which is bell-shaped towards the driver 33 . The skirt 48 is axially delimited by a base 46 fixed to the gear wheel 32 and a rear stop 47 fixed at the largest free end to the connecting piece 45 . Said skirt 48 and link 45 are rotating parts.

[0074] Bottom 46 extends radially between skirt 48 and gear 32 and has a planar annular bearing surf...

Abstract

A starter motor including an electric motor (11) mechanically coupled to a starter (26) including a driver (33), a hitch member (45) for hitching the pinion (32) to the driver (33) via a free-wheel mechanical coupling (34) in the form of a friction clutch, and a priming spring (R1) built into the starter (26) between the hitch member (45) and the driver (33), whereby the two friction surfaces (37, 40) are spaced apart when the friction clutch is in the inoperative position, and a resisting torque is frictionally generated to enable reliable priming of the self-locking function of the free wheel (34).

Description

[0001] starter for free wheel starter technical field [0002] The invention relates to a starter, in particular for an internal combustion engine of a motor vehicle, the internal combustion engine being provided with a flywheel with a toothed starter ring, the starter comprising an output shaft provided with teeth, a starter head, a gear belonging to the starter head, and An electric motor mechanically connected to a starter head for rotationally driving said output shaft, said starter head mounted on said output shaft in a rear idle position and said starter gear to said internal combustion engine flywheel Sliding axially between the front positions where the toothed starter ring meshes, the starter head consists of: [0003] a drive controlled by a controller between said forward and rearward positions and provided with a drive groove engaging said complementary toothing of said output shaft, [0004] The gear is connected to the connecting part of the drive by means of a ...
