FIELD: transport.SUBSTANCE: gearshift train comprises planetary gearbox, gearshift cam engaged with planetary gear in said gearbox and provided with retainer, spinning ring of cable connected with moving cable. Cable ring comprises section with ledges, spinning ring with ledges including section with ledges engaged with cable ring section with ledges. Besides, ring with ledges has retainer to be engaged with gearshift cam retainer. Cable ring spinning makes it displace through preset distance in direction perpendicular to cable ring spinning plane. Gearshift cam is retained by engagement with ring with ledges. Note here that at said preset distance ring with ledges can spin can spin with cable ring and displace axially at a time of axial displacement of ring with ledges and spring fitted between cable ring and gearshift cam. Gearshift cam responding to spring force spins at spinning of ring with ledges limited by gearshift cam engagement with retainer of ring with ledges while gearbox shifts gears at gearshift can spinning.EFFECT: higher reliability.3 cl, 58 dwg, 1 tbl |
