Multi-wheel walking driving system and electronic anti-slip method
The invention discloses a multi-wheel walking driving system and an electronic anti-slip method. A two-pump four-motor driving system is used, two sets of independent hydraulic systems are used, one pump supplies oil to two motors, electric proportional variable control motors can be used, and two-point type variable control motors can also be used. For an electric proportional control motor system, when the rotating speed difference exceeds a set value, the overspeed motor control current is increased, and then the displacement of the overspeed motor is reduced, so that the driving force provided by the motor matches the adhesive force, and slipping is reduced. For the two-point control motors, when the rotating speed difference exceeds a set value, a flow dividing control valve is automatically opened, so that the speeds of the two motors can be basically consistent, and overspeed is avoided. According to the scheme, active anti-slipping is achieved, control is simplified, and the control method is more intelligent. In addition, the motors are arranged diagonally, the slipping probability of the two sets of hydraulic systems is reduced at the same time, and driving force on the two sides can be effectively kept.
本发明公开一种多轮行走驱动系统及电子防打滑方法，使用两泵四马达驱动系统，为两套独立的液压系统，一个泵给两个马达供油，可以使用电比例变量控制马达，也可以使用两点式变量控制马达。对于电比例控制马达系统，当转速差超过设定值时，增加超速马达控制电流，进而减小超速马达排量，以使马达提供的驱动力与附着力相匹配，进而降低打滑。对于两点控制马达，当转速差超过设定值时，自动打开分流控制阀，以使两马达速度能基本一致，避免超速。本方案实现主动防打滑，简化控制，控制方法更加智能化。另外，马达采用对角布置，两套液压系统同时打滑几率降低，能有效保持两侧驱动力。
