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, and the vehicles are simple and practical and have good off-road performance. In an actual use environment, the all-terrain vehicle can face various complicated terrains, particularly when facing the terrains with larger gradient and steeper gradient, the lubricating oil in the oil pan is gathered to one side or flows back to the crankcase due to overlarge inclination amplitude of the vehicle, so that the oil pressure is insufficient, and the oil pump cannot supply oil. The all-terrain vehicle can not pass through the difficult terrain, and the practical effect of the all-terrain vehicle in the actual use process is reduced. Disclosure of Invention In order to solve the defects in the prior art, the invention aims to provide an all-terrain vehicle capable of improving climbing performance. In order to achieve the above purpose, the present invention adopts the following technical scheme: The all-terrain vehicle comprises a vehicle frame, a vehicle body panel, a walking assembly and a power assembly, wherein the vehicle body panel is at least partially arranged on the vehicle frame, the walking assembly is used for supporting the all-terrain vehicle, the power assembly is at least partially arranged on the vehicle frame, the power assembly comprises an engine, the engine comprises an ignition mechanism, a crankcase and an oil pan connected to the crankcase, the crankcase comprises an oil baffle plate, the oil baffle plate and the crankcase are integrally formed, an oil return hole is formed in the oil baffle plate, the projection area of the oil return hole on the projection plane along the axis direction of the ignition mechanism is a first projection area S1 on a projection plane perpendicular to the projection plane of the ignition mechanism, the projection area of the oil baffle plate on the projection plane along the axis direction of the ignition mechanism is a second projection area S2, and the ratio of the first projection area to the second projection area is more than or equal to 0.08 and less than or equal to 0.2. Further, the ratio of the first projection area to the second projection area is 0.09 or more and 0.11 or less. Further, the crankcase is formed with a first accommodation space around itself, the oil pan is formed with a second accommodation space around the crankcase, and the oil baffle plate partitions the first accommodation space and the second accommodation space. Further, the oil return hole communicates the first accommodation space and the second accommodation space. Further, the first projection area S1 is 1970mm 2 or more and 2970mm 2 or less. Further, the first projection area S1 is 2220mm 2 or more and 2720mm 2 or less. Further, the second projection area S2 is 20600mm 2 or more and 31000mm 2 or less. Further, the second projection area S2 is 23200mm 2 or more and 28400mm 2 or less. Further, the engine further comprises a crankshaft connecting rod mechanism, and the minimum distance D between the crankshaft connecting rod mechanism and the oil baffle is more than or equal to 2mm and less than or equal to 5mm. Further, the crankcase is provided with a first bearing seat, a second bearing seat and a third bearing seat, the second bearing seat is arranged between the first bearing seat and the third bearing seat, the oil return hole is at least partially arranged between the first bearing seat and the second bearing seat, and the oil return hole is also at least partially arranged between the second bearing seat and the third bearing seat. Through setting up the oil baffle with engine integrated into one piece to set up the ratio of above-mentioned first projected area and the second projected area of oil baffle to be more than or equal to 0.08 and less than or equal to 0.2, thereby reduced the manufacturing cost of engine, and avoided all-terrain vehicle oil pressure insufficient condition that leads to the vehicle unable marcing when difficult topography is driven, promoted the traffic capacity of all-terrain vehicle to difficult topography.
