Description

Motorcycle Technical Field The invention relates to the field of vehicles, in particular to a motorcycle. Background Motorcycles have become an indispensable part of life for people loving sports as a riding vehicle. A problem in motorcycle racing engines is that the arrangement of the oil pump and the scavenge pump wastes space and is of a relatively large overall weight. In order to meet the power and economy requirements of motorcycle racing, a more compact and lighter engine arrangement is required. Disclosure of Invention In order to solve the defects in the prior art, the invention aims to provide a motorcycle with an integrated lubrication system. In order to achieve the above purpose, the present invention adopts the following technical scheme: A motorcycle comprises a frame, a body panel, a walking assembly, a driving assembly and a driving assembly, wherein the body panel is at least partially arranged on the frame, the walking assembly is at least partially connected to the frame, the driving assembly is used for driving the walking assembly and comprises a shell and a lubricating assembly, the shell is provided with an accommodating space, the lubricating assembly comprises an oil pump and a scavenging pump assembly, the oil pump and the scavenging pump assembly are fixedly connected, and the oil pump and the scavenging pump assembly are arranged in the accommodating space. Further, the scavenging pump assembly comprises a first scavenging pump and a second scavenging pump, and the oil pump, the first scavenging pump and the second scavenging pump are fixedly connected and basically distributed along the first straight line direction. The shell further comprises a second oil inlet, a third oil inlet and a second oil outlet, and the second oil inlet, the third oil inlet and the second oil outlet are communicated through the scavenging pump component. Further, the length L1 of the housing extending in the first straight line direction is 127mm or more and 157mm or less. Further, the driving assembly is provided with a transmission shaft, the transmission shaft is connected with the oil pump and the scavenging pump assembly and is used for driving the oil pump and the scavenging pump assembly, and the length L2 of the transmission shaft extending along the first linear direction is more than or equal to 171mm and less than or equal to 209mm. Further, the ratio of the length L1 of the housing extending along the first linear direction to the length L2 of the transmission shaft extending along the first linear direction is greater than or equal to 0.6 and less than or equal to 0.9. Further, the driving assembly comprises a driving piece, and the lubrication assembly is connected with the driving piece through a transmission shaft. Further, the driving assembly further comprises an oil pan, and the width L3 of the oil pan along the first straight line direction is more than or equal to 260mm and less than or equal to 390mm. Further, in a direction parallel to the first straight line, a ratio of a length L1 of the housing extending in the first straight line direction to a width L3 of the oil pan in the first straight line direction is 0.35 or more and 0.53 or less.
