To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 3, the present invention provides a multi-speed transmission with an overrunning clutch, including an input shaft 10, an output shaft 20, a gear pair unit 30, a first intermediate shaft gear set 40, a second intermediate shaft gear set 50, a central shaft 60, a housing 100 and an overrunning clutch 01.
The overrunning clutch can be a wedge type overrunning clutch, a ball type overrunning clutch and a ratchet wheel type overrunning clutch. The overrunning clutch is sleeved on the output shaft and is positioned between a gear of a gear pair of the output shaft and the output shaft, and the overrunning clutch is an important part with power transmission and separation functions between a prime motor and a working machine or between a driving shaft and a driven shaft in the machine. The overrunning clutch is a device with a self-clutch function by utilizing the speed difference change of a driving part and a driven part.
For example, the wedge overrunning clutch uses a profiled wedge instead of a roller as a wedge part, and is a clutch with a friction pair consisting of a wedge 011, an inner roller path 012 and an outer roller path 013. When the inner raceway, the outer raceway and the wedge block do not move relatively, the rotation directions are the same, the rotating speeds are equal, the torque can be transmitted, otherwise, the torque is transmitted in a relative sliding mode, and the sliding state without the torque transmission is called overrunning. The wedge overrunning clutch mainly comprises a basic type, a non-inner-roller-way type and a type with a bearing. The connection form of the device is key connection, gear connection, belt wheel connection, chain wheel connection, bolt connection and the like.

Meanwhile, the second clutch is used for carrying out off-state operation on the common gear and carrying out on-state operation on the first sun gear, so that the power on the transmission intermediate shaft is transmitted to the central shaft through the central input gear and the gear pair of the first sun gear.
The third transmission path is: the first input gear is operated in an off state and the common gear is operated in an on state by the first clutch, so that the power of the input shaft is transmitted to the transmission intermediate shaft via the gear pair of the common gear and the input/output gear. Meanwhile, the second clutch is used for carrying out on-state operation on the common gear, and the first sun gear is used for carrying out off-state operation, so that the power on the transmission intermediate shaft is directly transmitted to the central shaft through the common gear.
The fourth transmission path is: the first input gear is operated to be in a disengaged state and the common gear is operated to be in an engaged state by the first clutch, while the first sun gear is operated to be in an engaged state by the second clutch and the common gear is operated to be in an disengaged state, thereby allowing the power of the input shaft to be directly transmitted to the center shaft. That is, power is transmitted to the transmission intermediate shaft through the gear pair of the common gear and the input/output gear, and then transmitted to the central shaft through the gear pair of the central input gear and the first central gear.
Because the input and output gears are meshed with the common gear to form a gear pair, the second input gear is meshed with the first input gear to form a gear pair, the central input gear is meshed with the first central gear to form a gear pair, and the gear ratios of the three sets of gear pairs are different. Therefore, when power is transmitted to the central shaft, the rotating speeds of the central shaft are four, and the purpose of changing the rotating speeds of the three groups of gear pairs is achieved.

Therefore, the first clutch is used for performing clutch operation on the first transmission gear and the first input gear, and the second clutch is used for performing clutch operation on the first linkage gear and the first central gear.
Specifically, the input shaft is provided with a first input gear and a first transmission gear, the transmission intermediate shaft is provided with a second input gear, a second transmission gear, a second linkage gear and a central input gear, wherein the second input gear is meshed with the first input gear to form a first input gear pair, the first transmission gear is meshed with the second transmission gear to form a second input gear pair, the second linkage gear and the first linkage gear on the central shaft form a first transmission gear pair, the central input gear and the first central gear on the central shaft form a second transmission gear pair, four groups of gear pairs are formed for transmission, and the gear ratios among the first input gear pair, the second input gear pair, the first transmission gear pair and the second transmission gear pair are different.
