The input shaft shaft is provided in the housing with a driving gear and a first a driving gear, the pitch circle of the second main wheel is lighter than the pitch circle of the first driving gear, and the output shaft wheel is disposed in the casing and has an output gear, and the transmitting unit 3 a moving shaft, which is spouted with the first driving gear and sleeved on the transmission shaft-passive wheel and a second passive wheel that is coupled to the second driving gear and sleeved on the shaft, the transmission is also private The glaze has a transfer wheel meshing with the output gear, the pitch circle diameter of the first break wheel is greater than the pitch of the second driven wheel ==: and (4) the two passive wheel (four) circle diameter is larger than the second active tooth, that is, the 0 diameter 'The synchronization H is set between the first-passive wheel and the second zone' and can be operated by - transmitting the first-passive wheel power to the transmission shaft position - to enable the second passive wheel power transmission To the second gear position of the drive shaft. The utility model has the following advantages: the transmission structure of the transmission unit is simple, and the transmission 7G can cooperate with the first driving gear and the second driving gear to achieve the deceleration (4), and the synchronization device and the transmission unit can be used together. Reaching the purpose of shifting can reduce the overall size of the gearbox to meet the needs of miniaturized design concepts. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is to be noted that in the following description, similar elements are denoted by the same reference numerals. As shown in FIG. 2 and FIG. 3, a first preferred embodiment of the present invention includes a housing 10 and an input shaft 2〇 disposed in the housing 1〇, an output shaft 30, and a transmission unit. 4〇, a synchronizer 5〇. The input shaft 20 is axially disposed in the housing 1 , and has a first driving gear 21 and a second driving gear 22 , and a pitch diameter of the second driving gear 22 is larger than a pitch circle of the first driving gear 21 . diameter. The output shaft 30 is spaced from the input shaft 20, and the shaft is disposed in the housing 10 and has an output gear 31. The transmission unit 40 has a transmission shaft 41 disposed between the input shaft 20 and the output shaft 3 , and is coupled to the first driving gear 21 and sleeved on the transmission. The first driven wheel 42 of the shaft 41 and a second driven wheel 43 that meshes with the first driving gear 22 and is sleeved on the transmission shaft 41. The transmission shaft 41 has a transmission gear 411 meshing with the output gear 31 and a bolt tooth portion 412 disposed on one side of the transmission gear 411. The first driven wheel 42 and the second driven wheel 43 are respectively rotatable and sleeved. It is disposed on both sides of the pin tooth portion 412. The pitch diameter of the first driven wheel 42 is larger than the pitch circle of the second driven wheel 43; and the pitch diameter of the second driven wheel is larger than the pitch diameter of the first driving gear 22. The synchronizer 50 is disposed between the first driven wheel 42 and the second driven wheel 43 and has a coupling to the transmission shaft 同步 $ synchronization hub, and is disposed on the synchronous gear hub 51 - μ α . The friction fits over the first pass of the first driven wheel 42. The gear 52, the first clutch 53 is tapered with the first clutch gear 52, and the second friction a is engaged with the second hybrid a of the first-passing gear. - a sigma gear 54, a second same with the second clutch gear 54, a synchronous core 56, and a synchronous toothed sleeve 56 and a driveable synchronization sleeve 56 along the transmission station _ ^ The axial displacement of the F-axis 41 is again 57. The synchronizing hub 51 has a pin groove portion 511 which is provided on the clothing surface and is coupled to the pin tooth portion 412, and a tooth detecting portion 512 provided on the outer surface. The synchronous toothed sleeve 56 M417319 has a hollow shape, and has a bolt groove portion 561 which is coupled to the bolt tooth portion 512 in the circumferential direction and is relatively displaceable in the axial direction, and a card slot 562 disposed on the outer peripheral surface. The shift fork 57 is inserted into the card slot 562. As shown in FIG. 2 and FIG. 3, the shifting fork 57 drives the synchronous toothed sleeve 56 to move toward the first driven wheel 42. The latching portion 561 is coupled to the detecting portion 512. The synchronous toothed sleeve 56 can cause the synchronous hub 51 to be structurally coupled with the first synchronizing ring 53 and the second clutch gear 52, and then use the synchronous trough 5 ι The portion 5U is coupled to the pinion portion 412, so that the rotational force of the input shaft 2〇 can be rotationally transmitted to the transmission through the synchronizer 50 after the first driving gear 21 drives the first driven wheel 42 to rotate. The shaft 41, again: by this, the moving gear 4U is combined with the output gear 31 (four), and finally the output shaft 3 is driven = the rotational force (power transmission is indicated by an arrow). When it is in the -right position, the first driving gear 21 is transmitted to the gear of the first driven wheel 42, and the eccentric electric motor can have a larger driving force to cope with the driving condition of the (four) slope. As shown in FIG. 4, when the dial 57 is operated and the Lange gear set % passive wheel 43 is moved, the % of the synchronizing sleeve can be used to make the door step teeth and the second synchronizing ring 55'. The two clutch gears are at the same time, and the splicing groove portion 5 of the 51 (51) 51 is connected to the record. 'The rotation force of the input shaft 20 is then passed through the second driving gear: 22, the nozzle of the second driven wheel 43 and the synchronizer can be transmitted to the transmission shaft 41, and then through the transmission gear; The meal of the wheel 31 is finally transmitted by the output shaft 3: the wheel is rotated like the arrow ay® (the power is not transmitted at the front). When the position of the second driving gear 22 is 6, the ratio of the second wheel to the second driven wheel 43 is small, so that the motor vehicle can have a larger wheel speed and can have a larger speed when walking on the ground. . Therefore, with the gearbox of the present invention, the electric motor vehicle can have both (4) and flat ground travel requirements. Furthermore, the present invention utilizes the transmission unit to cooperate with the first driving gear and the second driving gear to achieve the deceleration target, and By using the synchronizer and the transmission unit, the shift can be achieved... the overall volume of the shift phase can be reduced to meet the needs of the miniaturized design concept. As shown in FIG. 5 and FIG. 6, the second preferred embodiment of the transmission of the present invention is operated by electric control shifting, and includes a housing 1 〇, an input shaft 20, an output shaft 30, and _ The transmission unit 4 (), the synchronizer %, further includes an electronic control unit 6 〇 'the electronic control unit 6 〇 has a motor Η, a deceleration unit 62 driven by the motor 61 and the deceleration unit 62 The drive transmission lever 63' is fixed to the transmission lever 63. The deceleration unit 62 has a first reduction gear 62, which is driven by the motor 61, a second reduction gear 622 that meshes with the first reduction gear 621, and a wheel 623 that is fixed to the second reduction gear 622. And a drive gear 624 fixed to the wheel 623, the drive rod 63 has a tooth row 63 1 that meshes with the drive gear 624 and extends axially along the s-transmission rod 63. The motor 61 can be decelerated and transmitted through the deceleration unit 62, and the driving gear 624 drives the transmission rod 63 to drive the displacement 57 to generate displacement, thereby achieving a first gear position as shown in FIG. The shifting operation of the second gear position shown. The above description of the above is only a preferred embodiment of the present invention, and does not limit the scope of the implementation of the present invention, that is, the simple equivalent change made by the scope of the new application patent M417319 and the new description content. Modifications are still within the scope of this new patent.
