An Amphibious Vehicle (AV) is capable of planing with less power than prior similar size amphibious vehicles and using mostly off-the-shelf part. Leading rear wheel well flaps are biased forward against the hull bottom for on-road use, and pivot back to fill a gap between the hull and retracted rear wheel, reducing drag during in-water use.

Provided is a drive, in particular for an adjusting instrument for an exterior vision element for a motor vehicle, comprising a driving mechanism cooperating with a first electric motor. The driving mechanism is configured for, by energization of the first electric motor, driving respectively a first and a second element to be driven. The driving mechanism comprises a coupling mechanism cooperating with a second electric motor. The coupling mechanism is configured for, by energization of the second electric motor, selectively coupling the driving mechanism with respectively the first and the second element to be driven.

A gear-lever mechanism using meshing and pushing for rotation includes a shell; an input device including a driving gear; an output device including a supporting frame and a driven gear set; and a positioning device including a fixed bearing gear. The driven gear set includes a transfer-layer gear and at least one idler gear. The supporting shaft center of each transmission gear in the driven gear set is the sub-bearing point, with each transmission gear meshed with its adjacent drive gears to form two meshing points. The bearing point and the two meshing points form a triangular pushing area. At least two triangular pushing areas in head-to-tail connection form a meshing-pushing-lever-type torsion-output path curved from the driving gear to the fixed bearing gear for connecting and driving, to cause the gear set to rotate with a raising speed, and then reduce the speed and increase the torque.

A mechanical power transmission module (10) comprising a housing (100) and a plurality of parts forming an epicyclic gear train, one of the inputs/outputs (101) of which is immobilized in relation to the housing, the other two inputs/outputs comprising an input (120) and an output (130, 140), power being supplied by an input shaft (110) of the module, the input shaft (110) being coupled to the output assembly (130, 140) by means of the input assembly (120) in a first axial position of the shaft. The input assembly (120) comprises a through-bore (123) and the output assembly (130, 140) comprises direct coupling means (142), toward the through-bore (123), accessible in a second position obtained by axial translation.
