Description of the invention: [Technical field to which the invention pertains] In particular, the invention relates to a power shifting device for a power slamming control device for an locomotive. [Prior Art] For the locomotives currently on the market, there are two main types according to their power transmission. One is the beltless transmission with a 10 15 20 ί = ί speed transmission. The former is commonly known as the locomotive. Self-discharging, the latter is commonly known as the above-mentioned (four) transmission mechanism of the locomotive type, which has its advantages and disadvantages due to different ways of use. For example, the belt-less step-variable transmission type is smoother in the speed change process, and the operation is simple (4) special The mechanism is therefore suitable for the same flat roads. On the other hand, the shifting speed of the standard position requires the shifting mechanism to be the clutching action of the clutch, but the phase can be changed according to the road condition, so that the vehicle achieves the advantages of low performance. I am fascinated by the above-mentioned locomotives that use the slot shifting transmission mode. The slot change includes the roof plate clutch, the clutch line, the shifting shaft, and the grooved pedal. The operation of the standard shifting secret requires the (four) hand (four) interaction. , : Hand: The clutch line controls the pressure plate clutch, the manual throttle reduces the engine speed, and the pedal shift pedal controls the shifting shaft. The shifting action 'reaches the gear shifting function. If you encounter the plug 2 = the driver's control of the pressure plate clutch, throttle, brakes, and shifting shaft 5 1330233 guidance and other actions, not only consume the driver's physical strength, but also affect the mood, the driver can not concentrate, easy to cause a car accident. In order to solve the above problem, there is a device 1 force driver = car gear shifting device, thereby increasing the convenience of operation. However, due to external factors or "faults, the power drive, or the system can not be activated, the listener can not shift gears, so the way to complete the broadcast is not very satisfactory, there is still room for improvement ^ Mingren Because of this, in the spirit of active invention, the thinking of the power-shift control device of the second problem, after several research experiments, finally became the invention of this Jiahui world. [Summary] The invention is related to The power shift control device comprises: a gear 15 mann mechanism, a plate clutch, a centrifugal clutch, a shifting axle-light coupling mechanism, and a power steering axle, wherein the gear shifting mechanism comprises a first axle A plurality of first speed multiple second shifting gears, a g Η wheel and a first axle set 5 has a change 4 to recognize the first shift gear and selectively engage the first different gear ratio, thereby forming a different The 垩 离 C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C C To the pressure plate J Rotating power, and the centrifugal clutch can be the second axis, and its rotary power selective transmission to 20 1330233.

The platen clutch is not lightly coupled to the first shaft and the drive gear shifting mechanism is shifted. Therefore, the driver does not need a hand: the cumbersome operation of the phase 15 interaction can easily complete the shifting action of the engine with a simple control. In addition, if the power driver fails, the power driver can be disengaged from the gear shifting mechanism by the 丨 coupling mechanism, and the shift lever is operated by the operating lever, so that both the power driver and the operating lever can be used to control the shifting function.

In addition, the first gear 21 is combined with The power driver 10 is plugged in, that is, the power driver _ first drives the first gear 21 to rotate, thereby driving the second gear 22 to bypass. The second gear 22 is slidably disposed on the transmission shaft 24 and is selectively engageable with the second gear 23 or not. As shown in FIG. 5, the third gear 23 of the light-spinning mechanism 2 is sleeved on the shift drive, and the shaft 27 is on the shifting shaft 27 and is pivotally connected to the connection (10) and the operation #1_5, respectively. The other end is pivotally connected to the shifting shaft a, that is, the third gear 23 is rotatable via the connecting shaft 28 and the shifting shaft 16_. In other words, the third gear 23 can drive the shifting shaft 16 to rotate for shifting. . The lock 25 of the coupling mechanism 20 is adjacent to the second gear. The two transmission shafts 24 are disposed, and the bearing 29 is interposed between the lock and the second gear a. In the present embodiment, the lock 25 is a nut, and the drive shaft (4) is screwed with an external thread at a position where the lock 25 is screwed. The elastic member % is sleeved on the transmission shaft 24 and is interposed between the first gear 21 and the second gear 22. The elastic member 26 can be used to provide a pre-force to force a second gear transmission shaft to a second The position and the third gear 23 are not indented. Choose 'a'. In the present embodiment, the elastic member 26 is a compression spring. Please refer to FIG. 6 , which is a schematic view of the iiB-B section light-synthesis mechanism when it is not light-fitting, and FIG. 7 is a perspective view of the coupling mechanism of the preferred embodiment of the present invention when it is not coupled, and FIG. 3 and FIG. 3 and The difference between Figure 4 is that the former is in the unconverted state and the latter is in the light-spinning state. The rest of the mechanisms are identical. Ίο 15 20 In operation, as shown in FIG. 5, the fastener 25 is selectively screwed to a first position or a second position on the drive shaft 24. When the lock is in the first position (as shown in Fig. 4), the second gear 22 and the third gear (four) are mutually reciprocal, i.e., the power driver 10 and the shifting shaft 16 are coupled to each other. In other words, the movable 2 driver H) can drive the first gear 21 to rotate, thereby driving the second gear 22 to rotate. The second gear 22 is further engaged to drive the third gear 23 to rotate together, so when the coupling mechanism 2 is in the coupled state (eg, As shown in Fig. 3, the driver uses the power drive|§ 10 to drive the shifting shaft 16 to rotate for shifting. In the present embodiment, the power driver 10 is a motor. When the power drive 10 fails, the driver only needs to rotate the lock 25 to the second position (as shown in FIG. 7), at which time the preload of the elastic member % can force the second gear 22 to move outward' thus the second gear The second gear 23 is disengaged from the third gear 23 into an unengaged state, i.e., both the power driver 10 and the shifting shaft 16 are uncoupled. In other words, the second gear 22 cannot drive the third gear 23 to rotate, so when the light-closing mechanism is in the unhandled state (as shown in FIG. 6), the driving (four-stage) operating lever 15 drives the shifting shaft 16 to rotate for shifting. files. In this embodiment, the operating lever is an operating lever of a pedal. 8 is a schematic diagram of an engine idle speed according to a preferred embodiment of the present invention. With the above structure, when the engine 1 starts to start, the crankshaft is at a lower rotational speed, and the centrifugal clutch 3 is clutched (four). And the clutch housing 32 is in a separated state. Therefore, the power of the engine i is transmitted through the crankshaft 2 of 12 1330233, and finally to the position of the centrifugal clutch 3, the power transmission is terminated. Ίο 15 20 Please refer to FIG. 9 again, which is a schematic diagram of the operation of a preferred embodiment of the present invention. After the rotational speed of the crankshaft 2 is gradually increased, the clutch yoke 31 and the clutch housing of the centrifugal clutch 3 are acted upon by the centrifugal force. The 32-pressing contact rotates together. The power of the crankshaft 2 can be transmitted to the platen clutch 6 via the centrifugal clutch 3, the drive gear 4, and the transmission gear 5, and then transmitted through the first shaft 7 and the first shaft 8. To the drive wheel 19, the drive wheel 19 transmits the rotational power to the "vehicle rear wheel 40, which can be powered by a chain (not shown) provided on the axles of the drive rim and the rear wheel 21 (not shown). It is transmitted to the rear wheel 21 of the vehicle, so that the vehicle can generate the forward power. Please continue to refer to FIG. 1 for a shifting diagram of a preferred embodiment of the present invention, and please refer to FIG. 3 and FIG. 6 together. When the gear position is changed, if the coupling mechanism 2 is used, the driver only needs to press the switch 13 that controls the power driver 1; if the combination mechanism 2 is not facing, the driver needs to operate the lever at this time. 15, material drive shifting shaft 16 rotation And then the shifting lever ^ and the clutch lever 14 are actuated. The 'clutch lever 操控 first manipulates the cam plate 63 to push the clutch W 61 ' to disengage from the clutch friction plate 62. ;: TM toggles the first on the shaft 7 - one of the shifting gears 71, 72, 73, 74, or one of the second shifting gears 81, 82, 83, 84 on the second shaft 8, for axial movement and fitting to the adjacent In the present embodiment, a change of 71, 72, 73, 74 or a second shifting gear can be achieved. In this embodiment, the rotational power can be rotated by the second 13 1330233 on the shaft 8 The shift gear 81 meshes with the first shift gear 71 on the first shaft 7, and is transmitted to the rear wheel 4 of the vehicle via the drive wheel 19. As explained above, the shifting operation first pushes the clutch disc 61 with the cam plate 63. Disengaging the clutch friction plate 62' thus temporarily terminates the transmission of power, and then shifts the cam plate 63 after performing the shifting operation at 5 o'clock, causing the clutch plate 61 to be pressed against the clutch friction plate 62 again to transmit power. In this embodiment, both the power driver 1 and the operating lever 15 can be used to drive the shifting. 16 rotation, and then the clutch lever 14 and the shift lever 17 pivoted on the shifting shaft 16 are manipulated, and the shifting operation is performed, thereby improving the convenience and maneuverability of the shifting of the 10th gear, and the power driver is not generated. The occurrence of a fault leads to the absence of a shift.
