Abstract

This invention, regarding a gearbox structure for vehicle, is presented. A main shaft is equipped with a slide piece, where two sides of the slide piece equip gear wheels respectively for going forwards and for providing forces. The movement-jointed shaft is equipped with a reverse slide piece, where the movement-jointed shaft at the side of the reverse slide piece is equipped with two umbrella gear wheels respectively for going backwards and for going forwards, and the terminal shaft for shaft transmission is installed between two umbrella gear wheels. By the terminal shaft and gear wheels respectively for going forwards and for providing forces being all installed between two umbrella gear wheels respectively for going backwards and for going forwards, the width and the aspect of the gearbox are varied to be small. Also by the connection of the transmission umbrella gear wheels of the terminal shaft and two umbrella gear wheels respectively for going backwards and for going forwards, the small size characteristic of the gearbox can be fulfilled to improve the drawback of traditional big size of gearbox. Accordingly, the chain design used in the traditional gearbox and the noise generated by the large section length of the traditional gearbox are both disappeared.

[Technical field to which the invention belongs] The present invention relates to a gearbox structure for a vehicle. The gearbox structure is achieved by miniaturization of the gearbox. Ji Li a kind of [previously transmitted by the speed box 10 to the transmission shaft system was a moving gear and another gear 22 24, and used the slot 25 22, the front rain group is equipped with a technology] '习 知 沙 # 车 Transmission For the structure, please refer to the first two in which the two are opposed to each other and the three are driven. In addition, the internal and external transmission mechanism 10i S of the clutch used in the variable gear teeth is refined and used in between—the transmission shaft 12 and the upper one—transmission reduction gear 2 1 phase one The speed change gear 22 for reverse gears, the front gear is provided with an external gear wheel 2 4 and a reduction gear 21 is set between the four. The power of the bow and the engine will pass through a belt and a passive shaft 11, and the The passive shaft 11 is set in combination, so that the passive shaft 11 and the motion 'at the same time, the passive shaft 丨 丨 is located next to one of the transmission shaft 20 next to the transmission shaft 20 is sequentially provided on the transmission shaft 20 respectively. The shifting gear 23 and a booster speed sleeve 20 are opposite to the reverse gear U and the boosting speed gear 24 are opposed to the reverse shift gear 23 and the force on the shift shaft 20. The gear teeth 2 4 1 are used, wherein the clutches 2 4 1 and the bolt grooves 2 4 2, 2 5. Also, between the clutch state 2 4 1 and the shift gear 23 for advancing and the shift gear 24 for boosting, a corresponding block 2 4 3, 2 is provided. 4 4, the clutches 2 4 1 can be shifted on the shift shaft 20 outside the bolt slot 2 5 to select the change for the reverse 200526461 V. Description of the invention (2) Speed gear 22, forward The speed change gear 23 and the speed change gear 24 for boosting are meshed and driven to form four different gear changes such as a neutral reverse gear, a forward gear, and an afterburner gear, and then the transmission shaft 12 is opposite to the speed change. The transmission gear 23 used before the shaft 20 and the transmission gear 24 used for boosting are respectively provided with a forward transmission gear 14 and a boost transmission gear 15 °.

Combined with relative rotation, the power can be transmitted to the bevel gear 424 for backwards, which further drives the transmission bevel gear 51 and the final shaft 50 of the shaft to be combined with each other for transmission to the rear wheel. To achieve the purpose of reversing. 0 V. Description of the invention (7) Furthermore, when the vehicle makes the shift hub 4 5 into the forward afterburner through the shift lever 4 6 'see FIG. 4' 5 Haidi's second shift fork 4 4 3 will move the slider 432 so that it is embedded in the blocking groove 423 of the gear 431 for boosting, and the power is transmitted by the transmission gear 4 1 1 of the passive shaft 4 1 to link the linkage shaft When the 2 is rotated, the second gear 425 on the linkage shaft 42 also rotates, and transmits power to the gear 431 for afterburning, so that the gear 431 for idler is idled on the main shaft 43. || The gear 4 3 1 that was originally in the idling state will cause the slider 4 3 2 to be in phase 0i with the main shaft 4 3, and will relatively drive the main shaft 4 3 to rotate, further driving the other transmission gear 434 in sequence. 4th gear 428 4 bevel gear 4 2 7 bevel gear 5 1 and the final shaft 5 0 of the shaft drive Om gear engagement, so as to drive the rear wheels, thus achieving the purpose of urging the forward low speed, the large torsion. Therefore, in the present invention, a slider 43 2 is provided on the main shaft 43. A forward gear 433 and a boosting gear 431 are provided on both sides of the slider 43 2, and a reverse slider 4 2 is provided on the linkage shaft 42. 2. The reverse slider 4 2 2-the side linkage shaft 4 2 is provided with a bevel gear 424 for backwards and a bevel gear 427 for forwards, and the bevel gear 4 2 4 and Between the bevel gear 4 2 7 for forward movement, a final shaft 50 is driven by the shaft, and the final shaft 50 is located between the bevel gear 424 for backward movement and the bevel gear 427 for forward movement, and for force application. The gear 431 and the forward gear 433 are also located in the backward bevel gear 424 and the front

Page 11 200526461 V. Description of the invention (8) Between the bevel gears 427 used, the width direction of the gearbox 40 can be made smaller, and the bevel gears 4 2 4 for backward movement on the linkage shaft 4 2 and The bevel gear 427 for advancing the transmission bevel gear 51 of the final shaft 50 can reduce the size of the gearbox 40 to effectively improve the shortcomings of the large size of the conventional gearbox 10. At the same time, the invention The gearbox 4 0 is designed without the conventional gearbox _ 10 on the chain 3 5. Therefore, it can effectively improve the noise generated by the conventional gearbox 10 5 with a longer pitch after long-term use. Disadvantages. _ According to the above, it is only one of the best specific embodiments of the present invention, but the structural features of the present invention are not limited to this.
