摘要

The vehicle has a slowing down unit (60) that slows rotation of a combustion engine (1) and acts on a clutch (30) in upstream of a primary shaft (20) in a power transmission chain (2). The slowing unit is constituted of fixed and movable friction discs (32, 33) of the clutch, where the discs are permanently connected in rotation to a crankshaft (10). The disc (33) is moved between neutral, clutched and slowing down positions. An independent claim is also included for a method for shifting of a gearbox.
