Abstract
A hydrostatic bridge including two hydraulic motors each having two distinct operating cylinder capacities, both motors sharing an overall casing. The bridge has four main ducts of a first type (feed or exhaust) and two main ducts of a second type (exhaust or feed). The overall casing has three upstream ducts respectively connected to the first and second main ducts of the first type themselves connected to distribution ducts of the first motor, to third and fourth main ducts of the first type, themselves connected to distribution ducts of the second motor, and to first and second main ducts of the second type, themselves connected to distribution ducts of both motors. The bridge includes an anti-spin device capable of selectively reducing the flow rate in the first upstream duct and in the second upstream duct for selectively correcting spin of the first and second motors.
