Abstract

The invention relates to an oil lubricating structure of an engine. The oil lubricating structure comprises a box body, a gear set, a first oil storage tank, a second oil storage tank, an oil supply port and an oil pump. The gear set is arranged in the box body. The first oil storage tank is arranged below the gear set. The second oil storage tank is arranged below the gear set and is arranged above the first oil storage tank. The teeth of the gear set are lower than the flowing end of the second oil storage tank. The oil supply port is formed in the top of the tank body, the gear set or the second oil storage groove. The oil pump is communicated with the first oil storage tank and the oil supply port through an oil path. Oil in the first oil storage tank is supplied to the oil supply port and lubricates the gear set in a splashing or dropping way, or the oil can be directly output into the second oil storage tank and the oil in the second oil storage tank directly lubricates the gear set. Therefore, the gear set is simultaneously and directly lubricated and the lubricating oil is enabled to be splashed onto the gear set in large area on the whole.

Description

technical field

[0001] The invention relates to a structure of a gearbox for a motorcycle engine, in particular to an engine oil lubrication structure. Background technique

[0002] The oil-lubricating structure of the engine gearbox of the prior art is provided with casing, gear set, oil supply port, oil storage tank and oil suction port; And it can continuously supply oil to the gear set for lubrication in the form of splashing; the oil storage tank is set at the bottom of the inner space of the box and transports the oil to the oil supply port through the oil circuit; the oil suction port is set in the box and can store the oil in the box The lubricating oil accumulated in the oil tank is sent to the oil supply port.

[0003] In the oil lubricating structure of the engine gearbox in the prior art, because the oil supply port is arranged on the spindle of the gear set, so when the spindle rotates, the lubricating oil can rotate and splash out from the oil supply port, and...
