Abstract
The utility model relates to a water pump of a water cooling motorcycle, which comprises a lower pump body and an upper pump cover, wherein a pump cavity is surrounded by the lower pump body and the upper pump cover. The water pump also comprises a water pump shaft, wherein the water pump shaft penetrates through the pump cavity from the upper pump cover and is supported on the upper pump cover by a bearing, and an impeller is arranged on the water pump shaft; the pump cavity comprises a cooling water cavity and a steam and oil separating cavity which are isolated from each other, and a gas and oil inlet communicated with the gas and oil separating cavity is arranged on the upper pump cover; the cooling water cavity is communicated with a water inlet of the water pump and a water outlet of the water pump, and the bearing is positioned at the head of the gas and oil separating cavity; and the impeller on the water pump shaft is positioned in the cooling water cavity. When in use, oil mist moves in the gas and oil separating cavity, and the pressure of the oil mist gradually decreases so as to effectively separate the oil and steam.
Description
(1) technical field
The utility model relates to a kind of water-cooling motorcycle water pump.
(2) background technique
At present, known motorcycle crankcase vented construction mainly contains cylinder head cover ventilation and gearbox ventilation dual mode.Wherein crankcase and the gearbox owing to the straddle type motorcycle four stroke engine communicates, so the structure pedal motorcycle four stroke engine that adopts gearbox to ventilate mostly then generally adopts the structure of cylinder head cover ventilation owing to being subjected to the integrally-built restriction of car load.General common ventilation system can or be subjected to reason such as labyrinth spatial constraints because of the oil baffle poor sealing performance, exist the oil that produces in the crankcase to separate halfway phenomenon with steam, cause not only that the engine lubrication oil consumption is too fast will to cause comparatively serious pollution of atmosphere simultaneously.
(3) summary of the invention
For the oil that overcomes existing crank case vent structure existence separates halfway phenomenon with steam, in order to satisfy the lubricating requirement of water pump shaft bearing work, the utility model provides a kind of crank case vent system with cooling motorcycle engine water to combine the water-cooling motorcycle water pump of design with the engine cooling water pump body simultaneously.
The technical scheme in the invention for solving the technical problem is: a kind of water-cooling motorcycle water pump, comprise lower pump body and last pump cover, and described lower pump body and last pump cover surround pump chamber; Also comprise water pump spindle, described water pump spindle penetrates described pump chamber by the described pump cover of going up, this water pump spindle is bearing in described going up on the pump cover by bearing, described water pump spindle is provided with impeller, described pump chamber comprises the cooling water chamber and the Oil-gas Separation chamber of mutual isolation, offer oil and gas import on the described upward pump cover with described Oil-gas Separation chamber UNICOM, described cooling water chamber and pump intake and pump outlet UNICOM, described bearing is positioned at the head in described Oil-gas Separation chamber, and the impeller on the described water pump spindle is positioned at described cooling water chamber.
Further, be provided with the dividing plate that is provided with at interval in the described Oil-gas Separation chamber, form circuitous Oil-gas Separation passage between dividing plate and the dividing plate.
Further, the described head of going up pump cover has last cavity, and the head of described lower pump body has following cavity, and the described cavity of going up covers the described cooling water chamber of formation with following cavity; Described oil and gas import is opened in described last cavity top of going up the pump cover head.
Further, also be provided with the stuffing box gland that is positioned at described cooling water chamber on the described water pump spindle, also be provided with pad between described lower pump body and the last pump cover, described cooling water chamber and described Oil-gas Separation chamber isolate by described pad and stuffing box gland; The pad that is positioned at described Oil-gas Separation chamber is also offered the through hole that has of pump cover and lower pump body in the UNICOM.
The utility model in use, mist of oil is advanced in the Oil-gas Separation chamber, the pressure of mist of oil reduces gradually, to oil can effectively separate with steam.And the head in the Oil-gas Separation chamber that is positioned at of the bearing of water pump spindle, mist of oil can carry out effective lubricating to bearing.
The beneficial effects of the utility model are: 1. can effectively separate with steam oil.2. can carry out lubricatedly fully to the outside lip of water pump bearing and stuffing box gland, all no longer need independent lubrication system so comprise constituents such as water pump spindle and the water pump bearing component that run up in the water pump component.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of water-cooling motorcycle water pump comprises lower pump body 1 and last pump cover 2, surrounds pump chamber after described lower pump body 1 and last pump cover 2 cover, and pump chamber comprises the cooling water chamber 3 and the Oil-gas Separation chamber 4 of mutual isolation.The head of going up pump cover 2 described in the present embodiment has last cavity, and the head of described lower pump body 4 has following cavity, and the described cavity of going up covers the described cooling water chamber 3 of formation with following cavity, and the remaining part of pump chamber is Oil-gas Separation chamber 4.
Also comprise water pump spindle 5, described water pump spindle 5 penetrates described cooling water chamber 3 by the described pump cover 2 of going up, this water pump spindle 5 is bearing in described going up on the pump cover 2 by bearing 6, described water pump spindle 5 is provided with impeller 7, described go up pump cover 2 on offer oil and gas import with described Oil-gas Separation chamber 4 UNICOMs, this oil and gas import is opened in above described the last cavity of going up pump cover 2 heads.Described cooling water chamber 3 and pump intake and pump outlet UNICOM, described bearing 6 is positioned at the head (being the beginning part of Oil-gas Separation chamber and oil and gas import UNICOM) in described Oil-gas Separation chamber 4, and the impeller 7 on the described water pump spindle 5 is positioned at described cooling water chamber 3.
