FIELD: transport. ^ SUBSTANCE: brake regulator comprises case that doubles as braking lever. Said case accommodates screwworm gearing comprising worm-wheel and worm and screw gearing comprising gear wheel and screw aligned with aforesaid worm. Said gear wheel is articulated with worm and limited in axial direction. Case groove accommodates also gearing with drive gear fitted aligned with worm-wheel while drive gear is arranged aligned with gearing screw and coupled therewith by free-running coupling and overtime clutch. The latter comprises two half-coulings, one arranged to displace axially, aligned with gearing screw and coupled therewith to transmit rotation. End face of said driven gear has radial grooves. Second half-coupling of overtime clutch is made up of roller fitted in driven gear radial grooves to rest upon appropriate cover of the case. Roller is coupled with driven gear with tangential play corresponding to normal clearance in the case. ^ EFFECT: better regulation, simplified design. ^ 4 dwg |
