Problems solved by technology

At present, similar engines on the market can no longer meet this type of demand. In response to this type of demand, the inventor has developed a tricycle engine with a larger displacement (this engine is a separate application). In this type of engine, the existing lubricating oil circuit, no matter Whether it is a lubrication system with a single oil circuit or a dual oil circuit, neither can meet the demand

Abstract

The invention discloses a double lubrication circuit structure for an engine. Sealing ribs are arranged between power cavities of left and right bodies and a transmission cavity; after the left and right bodies are butted with a box surface for assembly, the sealing ribs serve as oil isolation belts to separate the power cavities of the engine from the transmission cavity; a power cavity lubrication passage and a transmission cavity lubrication passage which are independent of each other are formed on the left and right bodies, a transition body and a right cover; the power cavity lubrication passage is communicated with an oil pool at the bottom of the power cavity, and the transmission cavity lubrication passage is communicated with an oil pool at the bottom of the transmission cavity; the left body is provided with a power cavity oil pump; the right body is provided with a transmission cavity oil pump; the power cavity oil pump and the transmission cavity oil pump are coaxially arranged and are driven by an oil pump gear; the oil inlet / outlet of the power cavity oil pump is communicated with the power cavity lubrication passage; the oil inlet / outlet of the transmission cavity oil pump is communicated with the transmission cavity lubrication passage. Split lubrication passages are adopted, influence between the passages is reduced, the engine performance is improved and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to an engine double lubricating oil circuit structure. [0002] Background technique [0003] Most of the Chinese people have a poor foundation, and the rural population accounts for 70%. They are typical developing countries. Three-wheeled motorcycles are widely used as a means of transportation between motorcycles and cars, taking into account flexibility, economy and practicality. It is suitable for production, transportation and transportation, and has broad market prospects. Recently, with the vigorous development of the urban-rural integrated economy, the income level of farmers has steadily increased. This has further promoted the consumer demand for three-wheeled motorcycles in China, and at the same time, some consumers have put forward higher requirements for the power and comfort of three-wheeled motorcycles. Especially in the southwest region (Yunnan, Guangxi, Guizhou, Sichuan, Chongqing, etc.), according to market ...
