The forward speed ratios include a low gear, one to one, and overdrive.

In the described embodiment, the applicable affected ratios are gears 7-12.

The arrangement permits a hot shift between speed ratios of a gear transmission.

The at least three transmission gears are selectively engaged by at least three shifting sleeves.

By setting the speed ratios of various planetary gear trains, any speed change can be achieved.

The arrangement also permits a smooth progression of speed ratios.

The invention relates to a variable-speed transmission comprising a toroidal variator for continuously changing the gear ratio.

By rotating the shift drum shaft, each of the at least three transmission gears can be engaged in sequence.

The invention is characterised in that different transmission ratios can be adjusted on the reducing unit (3).

A vehicle transmission has at least three transmission gears.

The gear wheel pairs can be selectively coupled in, in order to form different gear ratios.

A shifter assembly (23) for selecting one of a plurality of gears of a transmission of a vehicle.

The gearwheels comprise six gearwheel groups for providing six gears respec- tively.

In many embodiments, the continuously variable transmission provides synchronous gear ratios and a continuously variable speed ratio.

Two sleeves and two additional low forward speed ratios are disclosed.
