The present application drives the planetary gear set to operate by setting a first power shaft that is transmission-connected to the output end of the engine. When the planetary gear set is in operation, it drives the first circulation turbine to rotate to drive the lubricating oil to circulate, and at the same time drives the second circulation turbine to rotate to drive the cooling water to circulate. The lubricating oil and the cooling water exchange heat in the water cooling chamber and the heat exchange chamber to take away the heat of the lubricating oil, thereby reducing the temperature of the lubricating oil. In addition, a heat dissipation chamber is set outside the water cooling chamber to dissipate the heat of the water cooling chamber through the heat dissipation chamber. A cooling fan is further set in the heat dissipation chamber and a ratchet assembly is set on the second power shaft for transmission. When idling, the locking of the gear ring is opened and the cooling fan is driven by the second power shaft. When driving, the locking of the gear ring is closed, and the cooling fan and the second circulation turbine are driven to rotate by the air intake of the cooling chamber. While realizing water circulation, the water around the water cooling chamber is dissipated. The faster the driving speed, the faster the speed of the cooling fan, thereby achieving the effect of non-powered drive and adaptive adjustment.

Description

Technical Field

[0001] The invention relates to an engine lubricating oil water cooling system, in particular to an engine lubrication and cooling system. Background Art

[0002] The basic task of a motorcycle engine lubrication system is to continuously supply clean, pressured, and temperature-appropriate oil to the friction surfaces of moving parts so that the engine can work normally.

[0003] Since the friction of parts generates a lot of heat, the temperature of the lubricating oil will rise significantly. The increase in lubricating oil temperature will reduce its viscosity, thereby weakening the lubrication effect, increasing the friction and wear of the bearing, and may cause the bearing temperature to rise further, and even cause oil film vibration and dry friction. To address this problem, the existing technology cools the lubricating oil by installing a water cooler outside the engine casing.

[0004] However, the external cooler has the problems of small heat exchange area and low heat exchange efficiency. Moreover, the external cooler needs to be driven by the power in the battery, and the energy utilization rate is low after multiple energy conversions. It cannot work when the engine is started and needs to be controlled separately. In addition, since the amount of cooling water used for circulation in the water cooler is limited, the water temperature becomes high after a period of use, which will cause the water cooling effect to weaken. Finally, the existing water cooler cannot judge the idling and driving status of the motorcycle, so as to perform targeted cooling. Summary of the invention

In this solution, the planetary gear set is driven by the first power shaft 401 connected to the engine output end. When the planetary gear set is running, it drives the first circulation turbine 101 to rotate to drive the lubricating oil to circulate, and drives the second circulation turbine 2031 to rotate to drive the cooling water to circulate. The lubricating oil and the cooling water exchange heat in the water cooling chamber 202 and the heat exchange chamber 100 to take away the heat of the lubricating oil, thereby reducing the temperature of the lubricating oil. The second circulation turbine 2031 is driven by controlling the locking gear ring 404 to rotate the rotating disk 405. The transmission ratio of the sun gear 402 and the planetary gear 403 can be set according to the needs. Generally, the heat generated at idling is less than the heat generated during driving.

[0040] Preferably, a heat dissipation cavity 303 is further provided in the engine housing. The heat dissipation cavity 303 is located outside the water cooling cavity 202 and has an air inlet 301 and an air outlet 302. When the motorcycle moves forward, wind enters from the air inlet 301 and exits from the air outlet 302, taking away the heat in the heat dissipation cavity 303.

In this solution, by arranging the ratchet assembly, in the stage of low heat dissipation demand, that is, the cooling fan 300 does not rotate with the second power shaft 501, and only needs to drive the cooling water circulation through the second circulation turbine 2031. When the heat dissipation demand increases, the cooling fan 300 can be driven to rotate by the wind passing through the heat dissipation cavity 303, and the second circulation turbine 2031 can be driven to rotate at the same time, thereby realizing the non-powered water cooling cycle and the heat dissipation near the water cooling cavity 202. When the engine stops rotating, this mode can dissipate heat inside the engine housing.

[0043] Preferably, the ratchet assembly includes a ratchet 503 arranged on the first section 5011 and a mounting frame 505 arranged on the second section 5012, and at least one pawl 504 is rotatably provided on the mounting frame 505, and a torsion spring is provided between the pawl 504 and the mounting seat to return the pawl 504, and the tip of the pawl 504 extends into the groove of the ratchet 503. When the motorcycle is idling, the ring gear 404 is locked by the locking mechanism, and the second power shaft 501 drives the planetary gear 403 to rotate and drives the rotating disk 405 to rotate, thereby driving the second power shaft 501 to rotate, and finally drives the second circulation turbine 2031 to rotate, and at this time the cooling fan 300 does not rotate with it; when the motorcycle is driving, the locking mechanism is released to lock the ring gear 404, and the cooling fan 300 rotates driven by the airflow, and drives the second circulation turbine 2031 to rotate through the ratchet assembly. This solution is a specific structure of the ratchet assembly. When the ratchet 503 rotates clockwise, the mounting frame 505 does not rotate along with it.

The first circulation turbine 101 and the second circulation turbine 2031 are dislocated by arranging the first cavity 2021, and the effective heat exchange area between the first circulation turbine 101 and the second circulation turbine 2031 and the heat exchange cavity 100 is increased by arranging the second cavity 2022.

[0047] Preferably, the locking mechanism is a locking motor with a self-locking function, and the motor shaft of the locking motor is connected to the middle of one of the supporting gears 406. The locking mechanism is used to control whether the ring gear 404 rotates, and whether the ring gear 404 rotates directly affects whether the rotating disk 405 rotates. When the ring gear 404 is locked, the rotating disk 405 can rotate. The three supporting gears 406 support and limit the ring gear 404. Except for the supporting gear 406 equipped with the locking motor, the other supporting gears 406 can rotate freely.
