The upper casing 1〇a is provided with a mounting hole u, and the upper and lower casings l〇a are formed into a closed accommodating space 13 for filling lubricating oil, and the lubricating oil can occupy the accommodating space 13 about 4 〇% of _, and the lubricant can be used to dissipate heat, lubricate and clean the parts. A socket 14 is protruded from the bottom surface of the accommodating space 13 . The pulley 2 is connected to the Na 21 by a device W pulley 2, and rotates with the pulley 20. 4 M359917 The axle 30 is disposed between the upper and lower casings 1a, and a plurality of IS fixing holes 3 are provided at predetermined positions of the axle 3, and the number of the fixing holes 31 of the present invention is two. The second limiting member 32 has a u-shaped shape, and the sub-position is Lai Dinghu fixed hole 31, wherein the fixing method can adopt mechanical or other equivalent fixing manner. The clutch 40 comprises a pull rod 4 - a paddle 44 and a tensile elastic crest 42 , wherein one end of the tension spring 42 is connected to the upper casing 1 〇 a, and the other end is connected to the pull rod 4 and the one end of the pull rod 轴向 is axially arranged - The sleeve 43 is disposed on the mounting hole U of the upper casing 1A, and the other sleeve 43 has a dividing groove 431. - the bottom piece 44' is provided with a lower joint piece 443 at the bottom end for insertion into the lower seat 14, and the other end is provided with an upper joint piece 44 for inserting the tie rod The inside of the cylinder 43 is such that the paddle 44 is positioned on the tie rod 41 to form an integral body. The other paddles 44 are in the shape of a C. The upper and lower dials 442 are provided on the open side for carding. Tongue wheel 5G. The movable wheel 5G has a ring groove portion & for the device to be privately placed therein, and the upper and lower dials 442 on both sides of the paddle portion 44 are limited. Wherein, when the pull rod μ is pulled by force, the pull cup 41 causes the flap 104 to swing, and when the tension is lost, it is reset by the tension spring 42. Shown by the second®, the schematic structure of the creative activity wheel®. The movable wheel 50 has a shaft hole 52' for rotating the movable wheel 50 on the axle 30. The movable wheel 50 - the side ring is provided with four first-earth teeth 53, each of the second one-way teeth has a high end and a low creep, and the second one-way life 53 has a plurality of heat dissipation holes 54. Please cooperate with the fourth map road - 4 圃 汁 juice is not a schematic diagram of the plane structure of the creative activity wheel. The positioning groove % is respectively arranged on both sides of the shaft hole 52 of the movable wheel 5, and the fixing % is connected with the shaft hole %, and the 5 M359917 (4) 2 circumferences are additionally provided with several groove %. When the paddle 44 is swung, due to the positioning slot, the inner wheel axle; the limiting member 32 can cause the movable wheel 5 (4) to generate an axial displacement on the axle % and be limited by the rotation direction. In addition, the axle wheel 3 is further provided with a drive wheel 60 for driving the wheel 60 for engagement with the worm 21 with respect to the movable wheel 50 and rotating therewith. Read the 7F of the fifth figure, which is a schematic diagram of the structure of the creation crane. The drive wheel (9) has a hole 61 for screwing on the axle 30, and the drive wheel 6 has a worm gear portion 62 for spraying the exhaust rod 21. Further, the driving wheel 60 is integrally formed at the other end and is provided with four first-way teeth 64'. The first-side one 64 is provided with a plurality of heat dissipation holes 65. Please refer to the sixth figure, which is a schematic diagram of the 6〇 plane structure of the driving wheel. The ring on the side of the worm wheel portion 62 of the display drive wheel 60 is provided with a plurality of groove phantoms. The first one-way tooth 64 of the driving wheel 60 corresponds to the second one-way tooth % of the movable wheel 5〇, and when the movable wheel 50 is displaced, the first and second one-way teeth 64 and 53 are mutually sprinkled to make the movable wheel 5〇 is driven by the driving wheel 60, and the movable wheel 5〇 can synchronously drive the wheel shaft 3〇 to rotate. It is worth mentioning that 'the movable wheel 50 and the driving wheel 6〇 are 7〇%~8〇% nylon (nykm) 3〇/ί> 20 A fiber mixed injection molding' so that the movable wheel 5〇 The driving wheel 6 has the characteristics of high temperature resistance and high strength; and the grooves 56, 63 and the heat dissipating holes 54, 65 are provided to reduce the molding compensation, make the weight lighter, and increase the surface area of the heat dissipation of the working state at the same time. When molding, it can reduce the deformation caused by cold shrinkage or uneven heat dissipation of the workpiece. 4 Refer to the seventh figure, which is a schematic diagram of the idling state of the wheel drive unit of the present creation. It is shown that when dial # 44 is in the normal position, the movable wheel % separates the driving wheel 6〇 and maintains a certain M359917 spacing, then the driving wheel 6 is in the idling state (as indicated by the dotted line), and the wheeling is not affected by the rotation. The movable wheel 50 is driven, but is in a stationary state. • Please take a look at the state of the creation wheel __ meaning state. It is shown that when the paddle 44 is in the operating position, the movable wheel 5〇 is swung by the picking piece 44, and is axially displaced on the wheel drawing 3〇, and is in harmony with the driving wheel 6〇, the driving wheel 6〇 is in the driving state. The drive wheel 60 transmits power to the movable wheel 50, and the movable wheel% can synchronously rotate the axle 30 (as indicated by a broken line). Φ In this way, the power transmission is sequentially the worm 2 drive wheel 60, the movable wheel 50, and the axle 3〇, so that the effect of the service creation is relatively direct, and no excessive power loss is generated. In combination with the above, the wheel drive device of the mower of the present invention has a driving wheel (9) integrally formed with the wheel portion 62 and the first one-way tooth 64, so that the design transmission structure is simple, and in the case of power transmission For the mast 2 drive wheel 6 〇, the movable wheel 5 〇 to the axle 3 〇, the transmission effect is more direct than the conventional structure without excessive _ force loss. Lu and the drive wheel 60 and the drive wheel 60 are made of a suitable ratio of nylon and fiber material and a plurality of heat dissipation holes 65, 65 or grooves 50, 63 are formed thereon, so that the movable wheel (10) and the drive wheel 60 have Light weight 'high temperature and high strength.
