Steering system for a steerable vehicle

A steering system for a steerable vehicle, comprising:

• at least two steerable wheels, each wheel connected to an electrically operable steering actuator to enable each electrically operable steering actuator to adjust a steering angle of a steerable wheel by application of a steering torque,
• wherein the electrically operable steering actuators are mechanically coupled to each other such that, in the event of a failure or malfunction of a first steering actuator, the steering torque provided by the second steering actuator is transferred to the first steering actuator, to enable a steering angle of the steerable wheel connected to the first steering actuator to be changed via the second steering actuator,
• wherein the electrically operable steering actuators are mechanically coupled to each other for the transfer of a torque from a first steering actuator to a second steering actuator, said steering actuators having a mechanical coupling,
• wherein the mechanical coupling has an elasticity of torsion such that a steering angle difference, which occurs during trouble-free operation, between the mechanically coupled steering actuators is compensated for, in the absence of transfer, by the mechanical coupling, and a steering angle difference exceeding a usual difference effectuates a transfer of the torque between the mechanically coupled steering actuators.
