A: Test Figure 1 and Figure 2. The above-mentioned vehicle shifting mechanism receives and transmits the power from the engine and the engine power transmission mechanism, and the previous stage mechanism is a stepless shifting mechanism. The stepless shifting mechanism transfers the engine power to the countershaft transmission gear 43 in detail. With the secondary shaft 4〇. The stepless shifting mechanism 19 includes an input shaft 20, an output shaft 26, a drive plate set 21, a drive plate (10), and a drive belt 25. The human shaft 2〇 transmits the engine power from the crank (not shown), and the output shaft 26 disposed parallel to the input shaft 20 is coaxially fixed—the output shaft gear 31 is coupled to the countershaft transmission gear 43 to drive the engine. Power is transmitted to the vehicle shifting mechanism. The drive disk unit 21 includes a drive plate 22, a slide drive disk, and a plurality of balls 24. The drive plate 22 is coaxially fixed to the input shaft 2〇, and the slide drive plate 23 is coaxially slidably disposed on the input shaft 2〇. A plurality of balls 24 are used to push the slide drive disk 23 to slide axially. Because of the rotation of the input shaft 2〇, the ball 24 is urged by its centrifugal force to push the sliding drive disk 23 to move axially along the input shaft 2〇. The drive plate set 27 includes a slide drive plate 28, a drive plate 29, and a drive plate spring 30. The sliding drive disc 28 is coaxially fixed to the output shaft % 12 200836948. The sliding drive disc 28 is coaxially mounted on the mountain soil 30 for sliding the shaft center on the output shaft 26 . Drive disc spring The spring pushes the top Si to slide. The drive disc spring 30 is axially moved by the retracting force to move the drive disc 28 axially along the output shaft 26. 5 15 20 The moving skin τ25 surrounds the driving disk group 21 and the driving disk group 27, and the action is to be wide 2. The rotary power is transmitted by the stepless shifting mode; the two sliding movement drive discs 23 and the sliding drive disc 28 can be moved toward the position by the centrifugal force. Then the transmission belt 25 will change its own driving disc group 21 and the transmission. Between the disc sets 27: The stepless shifting function is achieved.

When the catching lever 61 is pushed by the elastic preload of the elastic member 71, the pusher 73 is not actuated. The first output gear 51 and the second output shaft pivoted to the output shaft 50, 51 and the second output gear 52 are the same as the first output shaft 51 and the second output shaft. On the mountain, therefore, it does not directly drive the output shaft 50 to rotate. Since the shifting lever 61 is in the first position, the first card person's "beads" are pushed by the pushing portion 62 to the top of the yoke 53, that is, the steel, and bite - the first: the first hole 56 and The first engaging groove 58 pivots the gear 51 on the shaft 50, thereby causing the original coaxial pivoting to the output rotation. The Japanese output gear 51 and the output shaft 5 are combined with the body, and the synchronous two grooves 57 are 54 which are separated from the second engagement groove 59 and fall between the first and second wheel-out gears 52. The state of the engagement. This state 13 200836948 The lower bow I engine powertrain, shown by the _ output gear, is shown as a low speed slot. (4) The output of the wheel 5G is 'car-changing change, the engine speed to be changed (four) f engine speed In this embodiment, the current speed and the engine speed sensor and the vehicle speed sensing (4) can be used to automatically reach the speed sensor 76 and the engine speed sensor 77 for the _ vehicle speed and the output speed signal and the engine speed signal. To the electronic control dial speed (four) Ϊ = is defined in advance when the received engine speed corresponds to the corresponding relationship, that is, control motor drive rotation: push rod 73 moves, push rod 73 into (four) push shift lever fairy resistance tl 71 The force causes the axial movement to change. The speed-speed (four) starts to move toward the second position 卩2 and 15 20 fP2 = r, which indicates that the shift lever 61 is moved from the first position P1 to the second position k, and passes through a The transition position p〇, and the first engaging member 53 leaves the first card along the first slope 63a The slot 58.t shift lever 61 passes through the over=two engaging members 落 and falls to the grooves (1) and 612 for the respective corresponding output gears 5, but there is no-output gear at this moment. The output shaft 5 带 is driven, but the interruption time can be controlled by the moving speed of the shift lever 61 and the axial length of the pushing portion 62. Since the axial length of the pushing portion 62 affects the interruption time of the shifting, if Shortly, the interruption time is prolonged. Preferably, the design is about equal to the distance between the first through hole % and the second through hole 57. When one of the engaging members is pushed into the engaged state, the other engaging member is simultaneously lost. Pushing action to release the engagement, so that the interruption time is compressed to the lowest of 200836948, and the smooth shifting effect is achieved. However, the second test is pushed by the push rod 73 to pass the transition position-"Dadi-position P2, the second two-in-one The piece 54 is pushed into the first engaging groove 59 along the first slope (fourth), and finally pushed by the pushing portion 62 into the second * and second engaging grooves 59, and is engaged with the second output gear 52. ^第: The closing member 53 has left the first yoke slot and is dropped to the first through hole minus the first ^^^. In this state, the engine powertrain is driven by the second wheel-out gear μ to output the output shaft 50, and the vehicle is displayed as a high-speed gear. 10 15 20 Another:: It can also be designed as a simple manual mode according to the actual use. The movement of the idle speed lever 61 is switched to switch between different gear positions. When the vehicle speed changes again, 'when the weight is to be cut back again, the same as #地地;f manual operation, or the drive unit 72 automatically operates the wide electronic unit 75 to control the motor transmission mechanism % reverse' so that the push rod is retracted, On the other hand, the wide (three) breaking elastic member 71 is pushed to the first position ρι, and the actuation process is reversed, that is, in the order of FIGS. 6 to 4. The tea test chart 7' described above is exemplified by the design of two gear positions, but it is also easy to promote to three broadcast positions or even more slot designs. As shown in the figure, in another preferred embodiment, the pushing device 74 uses a solenoid valve driving mechanism to add a coaxially fixed third countershaft gear 83 to the sub-shaft 40, and the wheel is shouted. Correspondingly, the third output gear 85 is coaxially disposed and coaxial with the third counter gear 83. The third output gear 85 is also provided with a third engagement slot 81, and the output shaft 5〇 is opened accordingly. The third through hole 82, the third card=piece 84 is valleyd and movable to the space defined by one of the third engaging groove 8 and the third through hole μ, and one of the two grooves 611 and 612 of the shift lever in. 15 200836948 Therefore, the ejector portion 62 is designed such that when one of the three pushes 54 and 84 is pushed into the corresponding engaging groove and the through hole, the two pieces are separated from the corresponding engaging groove. That is, it does not engage with the corresponding gear, and thus the vehicle shifting mechanism with three gear positions can be achieved. Such as Zhuang this invention has the function of changing the groove without the need to add the auxiliary crying clothes, such as the pressure plate clutch device and the lever of the traditional gear shifting machine, and the interruption time of the mouth is very short compared with the conventional one. The process of making the groove change smoother, especially when used in conjunction with the power transmission that has the stepless speed change, the power can be transmitted through the stepless speed change mechanism and the slot, that is, each broadcast position can be = Constructing each other and doing this quickly. In this way, regardless of any road environment, high and low torque, speed of rotation or other occasions are applicable, and the maximum performance of the vehicle engine can be exerted. In addition, the present invention is simpler than the requirements of the prior art, and the group is not complicated, and the manufacturing cost is not complicated. It also has considerable advantages. The above embodiments are merely exemplified for convenience of explanation, and the present invention claims to be based on the above-mentioned embodiments.
