Loader walking and braking energy recovery auxiliary driving device and control method
The invention provides a loader walking and braking energy recovery auxiliary driving device and a control method. The walking and braking energy recovery auxiliary driving device comprises a controller, a signal monitoring module, a hydraulic auxiliary driving module and a brake module. The hydraulic auxiliary driving module comprises a pump/ motor, a three-way flow valve, a small-size accumulator, a large-scale accumulator, an overflow valve 1 and an overflow valve 2. The control method comprises a pump/ motor control step and a three-way flow valve control step. Through a three-way proportional control valve, torque impact on the pump/ motor is effectively eliminated, so that a loader is allowed to be more smooth and stable in the driving and brake process, the vehicle control performance can be improved; meanwhile, the three-way flow valve is higher in integration level; and compared with two or more switch valves, fault points are reduced, and the device cost is reduced.
