Description of the new model: [Technical field to which the new model belongs] The creation of gearboxes is related to the gearbox of the machine scale, in particular-a vehicle with a reverse gear [previous technology] and 3 ^ 23 and leisure tools For example, agricultural vehicles, handicapped vehicles, Wei, Wei, Wei, Secret _ heart, and a sharp speed in-phase gear set as a power transmission. The speed of σ-wenxuanhe S is as shown in the first and second figures, showing only the group of gears inside the gearbox (ΐίί The inside of the gearbox housing (11) is provided with a 1-moving gear-Weilu group (i 3), The transmission wheel set includes a plurality of transmission gears (丄 ′) on a pivot of the transmission shaft (1 2 1), and the transmission gears (1 2 2) are wheels arranged at a peripheral edge, and 2 2) The number of teeth on the periphery is not the same; and the transmission gear set (1 3) is composed of a plurality of transmission gears (work 3 2) on the top of a car, each 1 2 3) is The periphery is a platoon wheel, and each of the Wei gears ('(1 2 2 5 (13 2}). Therefore, when the gearbox is to be shifted during operation, it can be dialed by “-__ Move the speed change gear (1 3 2) of the speed change gear set (1 3) (======================= ===================================================================================== ================================== singing coefficients of the transmission gears of the wheel set (12; 5; 2}}} can be disengaged; The moving transmission gear (13 2) is matched with the transmission gear (12 2) of the transmission ^ 1 2) to complete the shifting action. The second wheel set (1 is the most suitable operating speed for operation. However, if it matches the actual use situation To adjust for immediate improvement Depression: Z, Zhong still has to be M270062. Because the transmission gears (12 2) of the transmission gear set (12) and the speed change gears, the (1 3) mouth high-speed gears (1 3 2) are in a corresponding meshing state. Therefore, the transmission gear set (1 2) will drive the transmission gear set (1 3) to rotate in the same direction, = each transmission gear (12 2) and each transmission gear (! 3 2) are in the opposite direction Transmission, change: In other words, the motor vehicle can only move in one direction, that is, it travels forward. However, agricultural vehicles and ATVs in motor vehicles encounter sand pits or low shaft shirts. It is not easy to reverse and get out of sleep. Similarly, when # 残 _car encounters a traffic jam, it is inconvenient to drive because of the inconvenience of '4 driver getting off the car and it is inconvenient. Β = 4 ^ The creator of this case is After careful consideration, I have accumulated many years of experience in various motor vehicles and / or affiliated Zhiqi Ji Touch #, and rely on the system and trial gear for the reverse of the motor vehicle gearbox. Χ 里 一 【New content】 To meet the purpose , As a weaving confession-a kind of following machine scale ^ ^ paragraphs include:-transmission case;-transmission gear set, which is made by- The moving shaft is provided with a plurality of transmission gears, and the transmission gears are internally:-a variable speed gear set, which is composed of a plurality of fan-changing special wheels on a shaft _ wheel together; this __ The point is that the sprocket is also called a reverse sprocket, and the shifting money M has = a reverse sprocket and a reverse transmission key sprocket set with a-key bar to make the reverse change: two the reverse transmission sprocket Synchronous rotation in the same direction. Sprocket /, M270062 — Regarding the techniques, means and other effects used in this creation to achieve the above purpose, a better feasible embodiment will be given with details of the drawings as described below. [Embodiment] ^ First, please refer to the second and third figures. The gearbox with a reverse gear provided by this creation is mainly a gearbox housing (20), a transmission gear. Group ^ 3 0) and a transmission gear set (4 0); wherein: The gearbox housing (20) can accommodate the following components in it. The transmission gear set (3 0) is composed of a plurality of transmission gears (3 2) on a transmission shaft (3 χ), and the transmission gear set (30) is set in the case. Inside the body (2 0). aThe shifting gear set (4 0) 'It is composed of-a plurality of = speed gears (4 2) are provided on the upper shaft of the shaft (4 1), and the shifting gear set (4 0) is set in the shifting The inside of the box suction body (20) and its transmission gear (42) are in mesh with the transmission gear (32) of the transmission gear set (30). _The creation of this case is characterized in that the transmission gear set (30) has a reverse transmission sprocket (33), and the transmission gear set (40) also has a reverse transmission sprocket (43), and the reverse The transmission sprocket (3 3) is at a certain distance from the reverse transmission sprocket (* 3), in other words, the two are not in an engaged state, and the reverse transmission sprocket (4 3) and the reverse transmission sprocket ( 3 3) A chain (50) is sleeved on the peripheral side, so that the reverse transmission sprocket (4 3) and the reverse transmission sprocket (3 3) rotate synchronously in the same direction. In actual design, the reverse transmission sprocket (4 3) and the reverse transmission sprocket (3 3) may have a gear ratio of 28:12. The above is the position of the interrelationship of the main structures of the creative embodiment. As for the assembly status and effect of this creative embodiment, please also refer to the second and third 7 M270062 for the operation of the gearbox. The shifting gears of the transmission gear set (4 0) are called by the rotation not shown. (4 2), = the gear shifting gear (4 2), which may be in contact with each other, is disengaged, and the dial gear (4 2) and the other transmission gear (3 2) fit together, so that the speed (4 2) is the transmission gear ( 3 2) The same thing: the motor vehicle goes to Ji Jin, which means that the prostitute becomes Lai Luan (4 2) ^ The machine is also supposed to change the Lai Lun (4 Q) through the lever unit, (4 p and this The reverse transmission sprocket (3 3) is driven. Because of the reverse speed change, 3) and the reverse transmission sprocket (3 3) rotate the financial direction _ through a key bar (/ (4 both, so it has to be 1 move 'to make The reverse speed sprocket U 3) and the reverse drive 'make the function of the drive by the motor vehicle having two different directions of the square drive transmission, so it can be increased ^ It is possible to change the groove for backward walking This creation is directed to agriculture In terms of cars and ATVs: When a ^ gets stuck in a sand pit or a low place, the farmer can use the function of _ ^ = ^ == 'difficult to travel backwards. t ;, slogan and pay attention to the creation of the book for the disabled car, as soon as possible to get out of sleep. Then get out of the car to carry out the movement of the cart, but in the case of the car, the driver's non-advance function, so that today The structural design of the defective product can be reversed so that the 3_early car can be smoothly released, and the convenience of driving is improved. The structure disclosed by shifting and returning, which mainly makes the motor vehicle powerful and effective. Increase the practicality of the motor vehicle, so the practicality of the creation of this M270062 is beyond doubt. In addition, the structure disclosed in this creative embodiment has been applied for ten years before it has been applied. It has not been used publicly, so the "newness, axe, and pace" of this creation is just like asking for a new patent, please read Huiyu) [Tie Debian.
