The structure of the utilization of the gram-type locomotive. [Prior Art] Today, the 'Kekta locomotive' has become an indispensable tool for daily life. Currently, most locomotives are powered by engines or electric motors. If the locomotive is equipped with an engine, the bow engine will drive the cylinder piston to generate power by burning gasoline, and use the battery power as the auxiliary power for starting the ignition. Furthermore, the engine must be equipped with a suitable transmission structure so that the power generated by the cylinder piston and crankshaft inside the bow engine can be smoothly transmitted to the rear wheels, causing the rear wheels to rotate to drive the locomotive forward. In addition, the locomotive's bow and the rear wheel of the rear wheel must also be equipped with appropriate suspension structures to provide shock cushioning. Therefore, how to design an appropriate transmission and suspension structure is also an important technology that is indispensable for the production of locomotives. In the case of the existing Scooter type locomotive, it is an integral oscillating engine that combines the engine with a rear-end transmission supporting the rear wheel, and the engine can be assembled up and down on the body frame. On the other hand, the sports locomotive fixes the engine to the frame of the vehicle body, and the rear arm can be moved up and down to be assembled in the body frame, and the engine driving force is transmitted to the rear wheel by the exposed chain. Loo year π月1日换页 However 'in this type of speed locomotive towel, the whole engine will be applied to the car body due to the weight of the engine t transmission, so it is necessary to increase the row weight 2, due to the displacement Increasing its weight is even heavier, causing the underarm to become heavier and worse. Furthermore, in sports locomotives, the power is transmitted by the exposed chain, so not only the noise is lower than A, the precision is reduced, and the life is also short, and the frequency of maintenance and repair is also increased. In order to overcome the above problems, the Republic of China Announcement No. 76 invention patent reveals that the driving device of the locomotive is fixed in the body frame - the engine support - the front end of the rear arm - the rear end support of the arm - The rear wheel, the secret-dry V-shaped skin = change = | § is arranged in the crankcase of the engine, and a wet reducer of a secondary transmission is fitted inside the rear arm. Since the engine is fixed to the vehicle body side and the dry V-belt shifter is disposed in the crankcase of the engine, the weight of the rear arm side can be reduced, and the suspension spring can be reduced. Furthermore, since the secondary transmission is mounted inside the rear arm, it is not necessary to transmit power by the exposed chain, so that the precision and the service life can be improved. Furthermore, the invention patent of the Republic of China Bulletin No. 1254686 discloses a suspension structure installation structure for a low floor type vehicle, which is applied to a speed skating type locomotive similar to the invention patent No. 431976, which is on a low floor. An engine is mounted below, and a rear wheel rear shock absorber is disposed at a slightly center position of the vehicle body. There is a storage box under the raft, and the front and rear lengths are slightly the same as the front and rear lengths of the seat cushion. Below the storage compartment, the rear wheel rear shock absorber is laterally disposed along a rear portion of the upper frame of the 1359766, which is extended from the back of the tube. Thereby, the accommodating space of the glove box provided under the seat is enlarged. However, the transmission and suspension structure disclosed in the invention patents No. 431976 and No. 1254686 still have the following problems in practical use, for example, although the wet transmission of the secondary transmission I is assembled inside the rear arm, However, gears and chains are still used for transmission, and the inside of the rear arm #谷#, A, the oil, thus increasing the overall weight of the rear arm, and the chain still produces a considerable buzz. Because the rear arm must: 4% complicated closed structure and oil return structure to avoid leakage of lubricating oil, which will help reduce the manufacturing cost and maintenance cost of the rear arm, and will save the shock absorber in the car. ^^再者' If the rear wheel is used in the rear, it can be inevitable by increasing the height of the storage compartment, but it is also inevitable: the rear length of the storage space is placed in the front and rear of the vehicle. Depth and increase the length of the early B-back, it does not car. In addition, since the rear wheel suspension y and the speed of the type can reach below, it is necessary to check the rear wheel for the rear shock absorber. However, it is convenient; ^. It is difficult for the repairer to change the rear shock absorber for the rear wheel by the viewing angle of the cover for the 4-phase, not only the maintenance convenience is low, but also the setting for the inspection. The cover increases the manufacturing cost and the selling price of the locomotive, and does not raise the competitiveness of the two products. Therefore, it is necessary to improve the structure of the speed locomotive locomotive to solve the problems existing in the conventional technology. 6 100 November 1 曰 Replacement page [Invention] The main purpose of this month is to provide a structure of a skating type locomotive.
