Power system for watering cart, watering cart and control method
The invention relates to a power system for a watering vehicle, the watering vehicle and a control method, the power system comprises a power assembly, the power assembly comprises a gearbox, the side face of the gearbox is provided with a power takeoff in transmission connection with an intermediate shaft of the gearbox, and an output shaft of the power takeoff is connected with a watering pump through an electromagnetic clutch; the control unit comprises a controller electrically connected with the electromagnetic clutch, and when the controller obtains that the gearbox is in the neutral gear and the rotating speed of the output shaft of the gearbox is larger than a set threshold value, the electromagnetic clutch is controlled to disconnect the power takeoff and the sprinkling pump. According to the power system for the watering cart, the gearbox and the load can be automatically disconnected to meet the requirement of free gear shifting when the watering cart moves and shifts gears without changing the operation habit of a driver. The situation that gear shifting needs to be carried out after parking when an existing watering cart is driven to take off power is avoided, the operation intensity of a driver is reduced, the working efficiency and safety of vehicle operation are improved, and meanwhile the service life of the clutch is prolonged.
本申请涉及一种用于洒水车辆的动力系统、洒水车及控制方法，包括：动力总成，其包括变速箱，变速箱的侧面设置有与变速箱的中间轴传动连接的取力器，取力器的输出轴通过电磁离合器连接有洒水泵；控制单元，其包括与电磁离合器电连接的控制器，当控制器获取变速箱处于空挡档位，且变速箱输出轴的转速大于设定阈值时控制电磁离合器断开取力器和洒水泵。本申请的用于洒水车辆的动力系统实现了在不改变驾驶员操作习惯，即可实现洒水车在行车换挡时，变速箱与负载自动断开满足自由换挡的需求。避免了当前洒水车行车取力时，需要停车后再换挡，降低了驾驶员的操作强度，提高了车辆作业的工作效率和安全性，同时也提高了离合器的使用寿命。
