Description
Technical field
The utility model belongs to technical field of motorcycles, specifically, and the particularly mounting structure of cooling motorcycle water water pump.
Background technique
Water pump is the vitals of cooling motorcycle water hydrologic cycle cooling system.Cooling motorcycle water is provided with cooling water tank, and the water in the cooling water tank is drawn into cylinder through water pump and carries out cool cycles, and then gets back to cooling water tank, accomplishes a water cycle cooling procedure.Like Fig. 6, shown in Figure 7, water pump is installed on the upper right quarter of right crankcase cover 3, form with water pump cover 2 two large divisions by impeller assembly 1, and through clutch driving gear drive work.The water inlet tap 2a of water pump is positioned on the water pump cover 2, and water outlet 2b is positioned on the right crankcase cover 3.Between water pump cover 2 and right crankcase cover 3, be formed with involute shape water cavity, water pump vane pumps the water that comes and flows in the cylinder block through this water cavity.The bolt 4 that discharges water of water pump is arranged in right crankcase and covers, so that in needs, the water in the hydrologic cycle cooling system is all emitted.Cover at right crankcase and also to be provided with spill pipe 7, this spill pipe 7 is positioned at the next door of horizontal oil channel hole 6, can judge through having or not water to flow out in the spill pipe 7 whether water pump is damaged.The deficiency of above structure is:
1) water outlet of water pump is independent member, and with right crankcase cover between adopt to press-fit and cooperate, one side needs independent processing and fabricating and installation, cost is higher; On the other hand, press-fiting quality directly influences its sealability, strict to assembly technology, occurs the water nozzle water leakage phenomenon easily.
2) spill pipe spatially intersects with horizontal oil channel hole, and distance is too near between the two, has only 3-4mm, in the die casting right crankcase cover, causes shrinkage cavity and trachoma many easily, and the phenomenon that water and oil phase are logical happens occasionally, and causes the scrappage of right crankcase cover high.
3) the involute shape water cavity that is formed with between water pump cover and the right crankcase cover is on two parts; Current need corner could get into the motor water pipe through this water cavity when terminal to get in the cylinder block again; Be easy to generate cavitation erosion and energy loss, thereby reduce the pump water yield, influence the water-cooled effect of motor.
4) bolt arrangement that discharges water of water pump covers at right crankcase, and this place is easy to generate trachoma, and water leak detection gas is more, often discharges water because of needs simultaneously, and the dismounting frequency is high, occurs the screw situation that gets a tooth pulled out easily, also can cause right crankcase cover to be scrapped.
5) water pump cover and right crankcase cover joint close gap require sternly, and slit between the two is not easy control, because of reasons such as processing and die wears, are prone to water pump cover and right crankcase cover interferes phenomenon.
The model utility content

More excellent scheme is: the endoporus of said water inlet tap (2a) is connected with the minimum place of water cavity (2c), and the endoporus of water outlet (2b) is connected with the biggest place of water cavity (2c).
The utility model with the mounting point of water pump by traditional central authorities that the right crankcase cover upper right quarter changes the right crankcase cover bottom into that are positioned at; Simultaneously the position of spill pipe is changed to the bottom of right crankcase cover; Make spill pipe away from horizontal oil channel hole, avoided spill pipe and horizontal oil channel hole to intersect the understanding and considerate condition of water oil phase that causes; Water pump cover is as a separate component, and is not tight with the requirement of right crankcase cover matching gap, more helps quick assembling; The turnover water nozzle all is arranged on the water pump cover, and the operation of reduced independent making on the one hand, water outlet being installed has reduced cost of production, on the other hand, has avoided press-fiting the water nozzle water leakage phenomenon that quality causes because of water outlet; Involute shape water cavity is integrated in the lid inwall, and water pump pumps the water that comes does not need corner just can directly get in the motor water pipe inflow cylinder block, has reduced the flow energy loss; And the endoporus of water inlet tap is connected with the small end of water cavity, and the endoporus of water outlet is connected with the big end of water cavity; Prevented that not only the water that gets into water cavity from refluxing; And further having reduced the flow energy loss, this structure has improved the pump water yield very effectively, has guaranteed the water-cooled effect of motor; Simultaneously, water pump places the right crankcase cover bottom, and flowing cold water has certain cooling action to the lubricant oil in the crankcase in the water pump, helps promoting the performance of motor.
Have water outlet screw (2d) in the bottom of said water pump cover (2), this water outlet screw (2d) communicates with water cavity (2c), and in water outlet screw (2d), the bolt that discharges water (4) is installed.Water outlet screw and the position of bolt of discharging water are moved to water pump cover by right crankcase cover, the water leak detection gas situation that can avoid the trachoma because of right crankcase cover to cause.
For the ease of manufacturing, further reduce cost, said water inlet tap (2a), water outlet (2b) and water pump cover (2) are the integrative-structure of die cast.
All be formed with journal stirrup (2e) in the right ends at said water pump cover (2) top and the right ends of bottom; Offer pilot hole on each journal stirrup (2e); Screw passes the pilot hole on the journal stirrup (2e) and extend in the screw on the right crankcase cover (3), and water pump cover (2) and right crankcase cover (3) are fixed together.Water pump cover is fixed through four points and right crankcase cover, connects firm, easy accessibility.
For simplified structure, be convenient to pipeline and connect and help water pipe and arrange; Said water inlet tap (2a) and water outlet (2b) are positioned between the last down journal of water pump cover (2) right-hand member; Water inlet tap (2a) is in the below of water outlet (2b); Both are parallel to each other, water inlet tap (2a) and water outlet (2b) all with inner port in last external port in the setting that has a down dip.
Beneficial effect: the utility model is through the mounting point of change water pump and the structure of water pump cover; The understanding and considerate condition of water oil phase that can avoid spill pipe and horizontal oil channel hole to intersect causing; When preventing that water nozzle from leaking; Effectively improve the pump water yield, guaranteed the water-cooled effect of motor, had simple in structure, easy, easy to assembly, the characteristics such as cost is low, long service life of transformation.
