Electric steering device for an articulated machine, particularly an earth-moving machine, with wheels controlled by independent electric motors

摘要: In an articulated machine, comprising a front assembly (2) with front drive wheels (3, 4) independent of each other, and rear assembly (5) drive wheels (6, 7) independent of coupled to the front articulation about an essentially vertical axis (12), the aforesaid and rear are driven by four corresponding electric motors (M1 - M4) which other. It is therefore possible in such a way that they transmit ground forces differing in modulus and/or orientation direction of rotation, order obtain desired steering angle between assembly (5). Thus hydraulic cylinders conventionally used to produce machine are eliminated, together circuit associated them. The system also comprises an auxiliary electric motor, controllable type, which drives pump forming part circuit the operating equipment machine.
