<p>The device incorporates a back pedal brake unit coupled to a ratchet bearer (23) on the take-off side. For operation of the brake by the driver (12), which is moved against drive direction, devices are activated to couple the driver to the brake, which suppress the effect of the free-wheel units for the drive. The devices also consist of free-wheel units, e.g. a first brake ratchet (5) mounted on a ratchet bearer (7) connected to the driver, and a second brake ratchet (25) mounted on a ratchet bearer on the take-off side. A control sleeve (13) with brackets (14) to control the brake ratchets is mounted on the driver during driving. A window sleeve to control three drive ratchets (24,26,27) is mounted on the take-off-sided ratchet to initiate a braking process.</p> |
