车辆发动机动力输出装置在特种车辆，如消防车、洒水车、扫地车、散装水泥车等领域应用广泛。按照取力方式的不同，可以将车辆发动机动力输出装置大体分为四类：变速箱上盖取力方式、变速箱副轴取力方式，夹心式取力方式和传动轴取力方式。Vehicle engine power output devices are widely used in special vehicles, such as fire trucks, sprinkler trucks, sweepers, bulk cement trucks and other fields. According to the different power extraction methods, the vehicle engine power output device can be roughly divided into four categories: gearbox upper cover power extraction method, gearbox countershaft power extraction method, sandwich power extraction method and drive shaft power extraction method.
其中，夹心式取力是在车辆离合器与变速箱之间加设齿轮箱的全功率取力方式。如公开号为CN112228535A的中国发明专利申请公开了一种对夹式全功率取力器，该取力器包括壳体，该壳体包括前连接架和后连接架，其中，前连接架用于连接发动机(如车辆发动机的飞轮壳)，而后连接架用于连接主驱动件(如车辆变速箱)；所述的壳体上设有启动齿轮安装孔、换挡齿轮安装孔和输出齿轮安装孔，在启动齿轮安装孔、换挡齿轮安装孔和输出齿轮安装孔位置处分别安装有依次啮合的启动齿轮组件、换挡齿轮组件和输出齿轮组件；Among them, sandwich power extraction is a full-power power extraction method that adds a gearbox between the vehicle clutch and gearbox. For example, the Chinese invention patent application with publication number CN112228535A discloses a wafer-type full-power power take-off. The power take-off includes a housing, which includes a front connecting frame and a rear connecting frame. The front connecting frame is used for Connect the engine (such as the flywheel housing of the vehicle engine), and then the connecting frame is used to connect the main drive part (such as the vehicle gearbox); the housing is provided with a starting gear mounting hole, a shift gear mounting hole and an output gear mounting hole. , a starting gear assembly, a shifting gear assembly and an output gear assembly that mesh in sequence are respectively installed at the starting gear mounting hole, shift gear mounting hole and output gear mounting hole;
其中，所述的换挡齿轮组件上还安装有拔叉和拔叉销，拔叉和拔叉销固定连接，其整体前后移动即可带动换挡齿轮啮合和脱离启动齿轮，进而控制输出齿轮的启停。Among them, the shift gear assembly is also equipped with a fork and a fork pin. The fork and the fork pin are fixedly connected. Their overall forward and backward movement can drive the shift gear to engage and disengage from the starting gear, thereby controlling the output gear. Start and stop.
上述的对夹式全功率取力器存在以下不足：(1)需要通过手动或电动换挡装置拨动拔叉和拔叉销才能改变换挡齿轮与驱动齿轮之间的啮合状态，不仅不方便远程控制，而且换挡机构故障率高，换挡稳定性差、生产成本高；(2)当取力器有负载(即取力设备)工作的情况下，需要取消取力时，汽车必须停下来才可以 脱档，难以在汽车行驶过程中取消取力，增加了操作过程的麻烦。The above-mentioned wafer-type full-power power take-off has the following shortcomings: (1) It is necessary to move the fork and the fork pin through a manual or electric shifting device to change the meshing state between the shift gear and the driving gear, which is not only inconvenient Remote control, and the gear shifting mechanism has a high failure rate, poor shifting stability, and high production costs; (2) When the power take-off is under load (i.e., the power take-off equipment), and the power take-off needs to be cancelled, the car must stop Only then can Out of gear, it is difficult to cancel the power take-off while the car is driving, which increases the trouble in the operation process.
