The power unit 2, as shown in Fig. 2, includes at least an engine 2 1, a transmission case 2 2 moved by the engine p 1, and a gear box 4 2 and a gear box 4_ The final shaft 2 3 5 drives the rear wheel shaft 24 ′ on the rear wheel shaft 24 through a chain 2 3 6 to provide a set of rear wheels 15. The action of the all-terrain vehicle m is shown in _2, which is mainly by mixing the new gas and secret introduced from the outside into oil and gas, and then combing the combustion chamber 2! The explosion generates power to cause the pistons 2 to 2 to reciprocate, and then the piston 212 drives the crankshaft 213 to make a circular motion. With this, the crankshaft 2 13 can drive the transmission case 2 2 connected to it. The transmission case 22 is provided with a belt transmission mechanism 3, and the belt transmission mechanism 3 U43ll5 includes a sliding disk 31 provided on the crankshaft p τ, u 丄 d, and one disposed on the crankshaft 2 丄 3 and located on the sliding disk 3 side. The drive plate 3 2 is a swash plate 3 3 which is disposed on the crankshaft 21 ^ and is located between the slide plate 3 i and the swash plate 3 3. 2-is restricted and accommodated in the heavy ball 3 4, A passive disk 3 6,1 capable of transmitting power on the passive _3 5, 1 a clutch 37 provided on the passive 1, a transmission belt 38. Wherein, the sliding disc 31 and the driving disc 32 form a driving belt 3a of the belt feeder 3. The driving end of the transmission belt 38 is located on the driving disc 3a, and the other end is located on the passive side. On the plate μ. = Change = The structure of M is a cake box. Lai Go 2 3 is mainly based on shifting 2 3 2 counties on the balance 2 3 χ, fine two sides _ face elastic 2 3 1 1, 2 3 1 2 Position to change the miscellaneous 2 3 2 position, so the slotted hub 2 3 2 can slide left and right on the shift hub shaft 2 1 1 d1, when the shift moves the vehicle forward 'from the fork 2 3 3 Forward fixed point 2 3 2! When moving, the exchange hub 2 3 2 was forced to slide and shift to the right, so that the compression spring 2 3 丄 2 was squeezed and contracted, so that the fork 2 3 3 could smoothly enter the groove change number. The forward fixed point 2 2 2 on 2 3 2 works, and at the same time, the dial 233 can push the slider 2341 on the main shaft 234 smoothly into the locking hole 23421 of the forward gear 2342. Similarly, when the standard change makes the car back, Because the dial 233 is moving to the backward fixed point 2322, the shifting Yi 2 3 2 will be forced to slide to the left, and the rotation spring 2 3 η will be squeezed and contracted ', so that the fork 2 3 3 can enter the person smoothly.

Finally, the 3 5 2 outside active toothed disc 2 3 5 2 is driven by the chain 2 3 6 The rear wheel vehicle is rotated from 2 to 4 and the rear wheel 15 is positive (reverse) to achieve the purpose of moving the car forward (backward). 0 The engine 21 pushes the piston 2 丄 2 for reciprocating motion by the power generated by the explosion. Therefore, the crankshaft 213 is driven to rotate, and the active obstacle 3 a of the belt transmission mechanism 3 is synchronously rotated by the action of the crankshaft 213. Therefore, the driven disc 3 is driven to rotate, and the driven shaft 35 is driven to rotate via the clutch 37, and the shifting mechanism 2 3 Shift to make the final shaft 2 3 5 rotate, and the final shaft 2 3 5 is _2 3 6 to _ • The passive gear 2 2 is set on the rear wheel shaft 2 4 to make the rear wheel work. 5 turns while making the all-terrain vehicle 1 travel. The goose • The habitual all-terrain vehicle m can, of course, make the all-terrain vehicle 1 travel freely through the above-mentioned transmission method. However, as I know, the main use of ATVs is to drive in areas with uneven terrain, so ATVs often have to hold the ground and read _ to read the situation of bribery cars, # 全 麟 赖"I throw up and re-low the ground", and after the Luo-di land, you need to speed up and rush forward, or when you need to rush up an uphill, this% Wangdi drive> Vehicle 1 must immediately force the big throttle at the moment of landing, Eli engine 2 1 for greater horsepower and torque output. The above-mentioned way of operating the all-terrain vehicle 1 is that when the all-terrain vehicle 1 landed, due to the gravity and the original suspension system of the all-terrain vehicle, the 1243115 system has made the active gear 2 3 5 2 and the passive gear 2 4 The purlin 2 3 6 is a noodle. At this time, if you want to increase the throttle again, the engine 2! And the belt shifting mechanism 3 will produce more horsepower and torque. ^ F 3 6 and the passive gear 241 will withstand momentarily. Large torsion and load, the chain 2 3 6 is loosened by strong stretching, or even cause the key 2 ^ to break, and at the same time, it will also be normal for all terrain vehicle operators. , Qiu Ge's meaning, and then the scene increased to, the use of ATVs 1 for the above-mentioned vicious driving methods, can not be resolved at all, and it is necessary to improve. Therefore, how to effectively eliminate the momentary large torque or load, and avoid the damage of the chain 236 and the passive gear disc 24, is a major issue for the all-terrain vehicle manufacturer, which needs to be solved. [Summary of the invention] The main purpose of the present invention is to provide an all-terrain vehicle with a gear box structure. The all-terrain vehicle lightly drives the belt transmission mechanism in the transmission box through the crankshaft of the engine to change the power through the belt.
