Description

All-terrain vehicle Technical Field The invention relates to the field of vehicles, in particular to an all-terrain vehicle. Background All-terrain vehicles are also called as all-terrain four-wheel off-road locomotives, the vehicles are simple and practical, the off-road performance is good, and the appearance is general without a awning. The whole axial length of structural arrangement of the traditional generator on the engine is longer, the overlarge space is occupied in the limited arrangement space, meanwhile, the whole weight of the generator is larger, the mass center balance of the all-terrain vehicle is affected, and the control feeling of the whole vehicle is reduced. When the generator is arranged on the engine, a rear cover used for forming a working chamber of the generator is required to be arranged independently, namely, a rotor, a stator and the rear cover of the generator are arranged as three independent parts, so that the production cost of the generator is improved, and the light-weight effect is poor. Disclosure of Invention In order to solve the defects in the prior art, the invention aims to provide an all-terrain vehicle with a lightweight generator. In order to achieve the above purpose, the present invention adopts the following technical scheme: An all-terrain vehicle comprises a vehicle frame, a vehicle body panel at least partially arranged on the vehicle frame, a walking assembly used for supporting the all-terrain vehicle, a power assembly at least partially arranged on the vehicle frame, wherein the power assembly comprises an engine and a generator at least partially arranged on one side of the engine, the engine comprises a crankshaft, the generator comprises a stator and a rotor connected to the crankshaft, the stator is connected to the engine and forms an accommodating space, the rotor is arranged in the accommodating space, and the ratio of the length D of the rotor along the extending direction parallel to the crankshaft to the peak power P of the generator is more than or equal to 0.41mm/kw and less than or equal to 0.63mm/kw. Further, the ratio of the length D of the rotor in the extending direction parallel to the crankshaft to the peak power P of the generator is 0.46mm/kw or more and 0.58mm/kw or less. Further, one end of the crankshaft is provided with a fixing portion, the fixing portion and the crankshaft are integrally formed, and the rotor is connected to the crankshaft through the fixing portion. Further, the rotor is provided with a first positioning member extending in an axial direction of the rotor for positioning between the rotor and the fixing portion, and the fixing portion includes a connection hole through which the rotor is coupled to the fixing portion with a fastener. Further, the length D of the rotor in the direction of the rotation center line of the crankshaft is 61mm or more and 93mm or less. Further, the length D of the rotor in the direction of the rotation center line of the crankshaft is 69mm or more and 85mm or less. Further, the peak power P of the generator is 32kw or more and 48kw or less. Further, the peak power P of the generator is 36kw or more and 44kw or less. Further, a second positioning piece used for positioning the stator is arranged on the engine, and the second positioning piece is arranged on one side, close to the generator, of the engine. Further, a positioning hole matched with the second positioning piece is formed in the stator, and the second positioning piece is arranged in the positioning hole when the stator is connected to the engine. By setting the ratio of the length D of the rotor in the extending direction parallel to the crankshaft to the peak power P of the generator to be 0.41mm/kw or more and 0.63mm/kw or less, the length of the generator extending in the axial direction of the rotor is reduced, the volume of the generator is reduced, and the space occupied by the power assembly in the whole vehicle arrangement is reduced.
