Vehicle with a hydrostatic transmission and steering system by steerable wheels and slip steering

摘要

The vehicle comprises at least one pair of wheels (5, 5a) and means (13, 13a) making it possible to connect, via the passages of the respective sections of the adjustable, or to be isolated from one another, on the one hand, the supply pipes (9, 9a) of the two loops (3, 3a) of the hydrostatic transmission and on the other hand, the return ducts (10, 10a) of the two loops (3, 3a). The vehicle also comprises means making it possible to adjust the respective capacities of the hydraulic pumps (1, 1a) of the transmission of an identical manner to the configuration of progression in a straight line or in turn by steering wheels and in differential manner to the configuration of progression of the bend by slipping, by mixing of the two types of direction, or to the configuration of the pivot about the center of gravity of the vehicle.
