The utility model comprises an oil pump body, an oil pump driving shaft which is driven by a crankshaft, a water pump body and a water pump impeller, the impeller is rotatablely connected at the shaft end of a water pump shaft, the utility model is characterized in that the two points of an oil pump driven shaft are supported at the bearing parts of the oil pump body and a pump base, the other end of the driven shaft is extended out of an oil pump cavity, the shaft end is provided with a drive combination part; one end of the water pump shaft is equipped with the water pump impeller, and the other end is provided with the drive combination part which is fixedly combined with the oil pump driven shaft. The drive combination part is the incision combination or the U-typed groove gomphosis. The utility model changes the drive power of the water pump from a drive gear which is connected with the crankshaft to the connection of the oil pump driven shaft, thereby saving the water pump drive gear, leading to the structure of the engine be compact and reasonable, reducing the manufacturing cost of the engine and reducing the oil consumption of the engine, thus, the utility model has good economic benefits.
Description
Technical field
The utility model belongs to two-wheel vehicle engine manufacturing technology field, the motorcycle engine of the architecture advances that particularly a kind of oil pump combines with water pump power.
Background technique
The oil pump of motorcycle engine is the critical piece of engine lubrication system, and water pump then is the critical piece of engine water-cooling system for water, and they all are positioned at the crankcase side and are adjacent.Oil pump in the engine lubrication system is by actuation gear on the bent axle or valve cam chain drive, the driven gear of driving gear or chain transmission oil pump shaft.Oil pump shaft is in the oil pump pump chamber, and pump shaft is except bearing driven gear, and pump shaft is not connected with other parts, a part of power of the oil pump pump shaft that left unused.Engine water pump is the core component of motorcycle engine constituent, because the rotating speed of Centrifugal water pump can not surpass 6000r/min, therefore, can not directly pass through the bent axle transmission, and water pump rotates by the actuation gear through slowing down, self-organizing system independently are set.
The design of this engine structure is unreasonable, and is also not compact, if, the idle power of oil pump driven shaft is combined with the water pump actuator, not only can save the actuation gear of water pump, make engine structure be tending towards more reasonable again, compacter.
Summary of the invention
The purpose of this utility model provides a kind of compact structure, improves the motorcycle engine of driven shaft power utilization.
Above-mentioned purpose of the present utility model can be achieved through the following technical solutions:
A kind of motorcycle engine of architecture advances, comprise oil pump body, the oil pump drive shaft of crank-driven, the oil pump driven shaft is by being engaged and linked with driving shaft gear, water pump body and water pump vane, impeller are screwed in the water pump spindle axle head that is positioned at the water pump chamber, it is characterized in that 2 of oil pump driven shafts are supported on the bearing portion of oil pump body and pump seat, the driven shaft the other end stretches out the oil pump chamber, and axle head is provided with one and drives conjunction; Water pump spindle one end is installed water pump vane, and the other end of water pump spindle is provided with the driving conjunction with oil pump driven shaft shaft end secure bond.
The motorcycle engine of described architecture advances, feature be the oil pump shaft axle head with the driving conjunction of water pump spindle axle head be otch combine or U type groove chimeric.
The utility model extends pump chamber to an end of oil pump driven shaft, and the oil pump shaft shaft end is designed to drive conjunction, realize combining with the power end of water pump spindle, the driving power of water pump changed into oil pump driven shaft output terminal by the actuation gear that originally was connected with bent axle be connected, save water pump driving gear.
The utility model not only makes the engine structure compact and reasonable, has reduced the motor manufacture cost, and has utilized the idle power of oil pump driven shaft, makes motorcycle can reduce the oil consumption of motor in motion, has good economic benefit.

Embodiment
Below be a specific embodiment of the present utility model:
Referring to Fig. 1, the motorcycle four-stroke engine, comprise the oil pump drive shaft and the meshing transmission of oil pump driven shaft (16) of oil pump body (15), crank-driven, water pump is located at crankcase one side, pump shaft one end of water pump body (2) is positioned at water pump chamber (6), noose is at water pump spindle (8) axle head in rotary manner for water pump vane (7), and water pump spindle (8) another axle head of impeller relatively is designed to the otch conjunction, is used for oil pump driven shaft (16) axle head fixedly connected.(16) two bearing portions that are supported on oil pump body (15) and pump seat of oil pump driven shaft, an end of oil pump driven shaft (16) is overhanging in the pump chamber, and the axle head shape is the otch conjunction, and it is fixedly connected to be convenient to same water pump spindle (8) axle head otch spare.
The utility model has realized that water pump combines with the power transmission of oil pump, the rotating speed of pump meets the requirements, make the idle power of oil pump driven shaft obtain utilization like this, save water pump driving gear, the energy consumption when helping reducing motor manufacture cost and engine running.
