Brake device for a reverse gear in a gearbox

摘要

Reverse gear brake device comprising a reverse gear shaft 16 on which a reverse gear pinion 12 moves by means of an inverter lever 17 driven by a reverse gear control shaft 1 equipped with its clutch claw 25, characterised in that the approach travel of the said reverse gear pinion 12 corresponds to a displacement of the reverse gear control shaft 1 during which the said control shaft 1 entrains a synchroniser 47 by means of a system for securely fastening the reverse gear control shaft 1 to the control shaft 4 of the gear corresponding to the said synchroniser 47, the said control shaft 4 being combined with a system for allowing the limited displacement of the said control shaft 4. <IMAGE>
