Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail embodiment of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technological scheme, and contribute to its enforcement.
As shown in Figures 1 to 4, the utility model provides a kind of planet carrier of integrated oil path, and comprise planet carrier body 1, planet carrier upper cover 4, planet carrier lower cover 5 and be arranged at the planet axis 11 of planet carrier body 1 center, planet axis 11 is hollow shaft.Planet carrier body 1 is disc-shaped structure, is provided with the high-pressure oil passage into clutch hydraulic pressure oil supply cylinder, the low pressure oil way for clutch counter balance pocket fuel feeding and the pressure release oil circuit for the pressure release of clutch counter balance pocket in the inside of planet carrier body 1.Planet carrier body 1 is provided with clutch plunger 3 and clutch retraction piston 2, planet carrier, under the cooperation of clutch plunger 3 and clutch retraction piston 2, forms the activating pressure of clutch.This planet carrier integrated oil path is used for providing elevated pressures oil to clutch hydraulic cylinder, provides lower pressure oil to clutch counter balance pocket, to realize the separation of short time internal clutch and to close, reduces band exclusion power; Simultaneously two non-pressure oil circuits can, as the pressure release oil circuit of counter balance pocket, make counter balance pocket draining more rapid, and as lubricating oil path, lubricate around rotational parts.
Specifically, the high-pressure oil passage in planet carrier body 1 leads to high pressure oil, closing for clutch; Low pressure oil way continues logical low pressure oil, is used for the oil pressure in balance hydraulic cylinder during separated state, to reduce the band exclusion power of clutch, improves mechanical efficiency and clutch friction plate working life; Pressure release oil circuit, can oil extraction more rapidly as the non-pressure draining oil circuit in equalizing piston chamber, increases reaction velocity when clutch engages, and the oil simultaneously released can be used for the lubrication rotary component such as bearing around.
As shown in Figure 2, the filler opening that high-pressure oil passage comprises the first oil duct 6 and the second oil duct 7, first oil duct 6 is communicated with the endoporus of planet axis 11, and the filler opening of the second oil duct 7 is communicated with the first oil duct 6, and the oil outlet of the second oil duct 7 is communicated with clutch hydraulic cylinder.The one end open of the first oil duct 6 is be positioned at the filler opening on the madial wall of planet axis 11, is provided with the plug stifled 12 for closing this end opening in the other end opening of the first oil duct 6.Plug stifled 12 is preferably steel ball, to prevent pressure oil from leaking, ensures the abundance of oil mass and oil pressure.
As shown in Figure 2, the first oil duct 6 and the second oil duct 7 are straight oil duct, and the length of the first oil duct 6 is greater than the length of the second oil duct 7.The axis of the first oil duct 6 and the axes intersect of planet axis 11 and non-perpendicular, the angle between two axis is less than 90 degree.In the present embodiment, high-pressure oil passage is circumferentially evenly equipped with two in planet carrier body 1.The cavity of high pressure oil by being formed between planet carrier body 1 and planet axis 11, first oil duct 6, and the other end place of the first oil duct 6 is sealed by steel ball, therefore the hydraulic oil of high pressure can pass through the first oil duct 6 and the second oil duct 7, thus arrive the oil hydraulic cylinder of clutch, piston is moved, closed clutch.
As shown in Figure 3, the filler opening that low pressure oil way comprises the 3rd oil duct 8 and the 4th oil duct the 9, three oil duct 8 is communicated with the endoporus of planet axis 11, and the filler opening of the 4th oil duct 9 is communicated with the 3rd oil duct 8, and the oil outlet of the 4th oil duct 9 is communicated with clutch counter balance pocket.The one end open of the 3rd oil duct 8 is be positioned at the filler opening on the madial wall of planet axis 11, and the other end opening of the 3rd oil duct 8 is positioned on the outer side wall of planet carrier body 1.The cavity of low pressure oil by being formed between planet carrier body 1 and planet axis 11, enter the 3rd oil duct 8, the opening that 3rd oil duct 8 is positioned on planet carrier body 1 outer side wall is stopped by the miscellaneous part of planet carrier outside, increase the local resistance of oil circuit, thus most of oil can be made all to lead to the 4th oil duct 9, and the other end of the 4th oil duct 9 leads to clutch counter balance pocket, the oil pressure produced by centrifugal force in oil hydraulic cylinder during in order to balance clutch separation state, reduce band exclusion power, make the control of clutch more accurate.Meanwhile, the outflow of lubrication oil end of the 3rd oil duct 8 flows to outside miscellaneous part, is used for the parts such as lubrication bearing.
As shown in Figures 2 and 3, the 3rd oil duct 8 and the 4th oil duct 9 are straight oil duct, and the length of the 4th oil duct 9 is greater than the length of the 3rd oil duct 8.The axis of the 3rd oil duct 8 and the 4th oil duct 9 and the axes intersect of planet axis 11 and non-perpendicular, corner dimension between the axis of the angle between the axis of the 4th oil duct 9 and the axis of planet axis 11 and the first oil duct 6 and the axis of planet axis 11 is equal, is all less than 90 degree.Angle between the axis of the 3rd oil duct 8 and the axis of planet axis 11 is greater than 90 degree, the filler opening of the 3rd oil duct 8 is positioned at the inner side of the filler opening of the first oil duct 6, and the distance namely between the filler opening of the 3rd oil duct 8 and planet carrier upper cover 4 is less than the distance between the filler opening of the first oil duct 6 and planet carrier upper cover 4.In the present embodiment, low pressure oil way is circumferentially evenly equipped with two in planet carrier body 1.
As shown in Figure 4, the filler opening that pressure release oil circuit comprises the 5th oil duct the 10, five oil duct 10 is communicated with clutch counter balance pocket, and the oil outlet of the 5th oil duct 10 and the oil outlet of the 3rd oil duct 8 are positioned on the same outer side wall of planet carrier body 1.In the present embodiment, pressure release oil circuit is circumferentially evenly equipped with two in planet carrier body 1.Low pressure oil in clutch equalizing piston chamber discharges equalizing piston chamber by the 5th oil duct 10, and the 5th oil duct 10 one end connects clutch counter balance pocket, and the other end can make lubricant oil flow out, for lubrication and cooling rotary component from outflow of lubrication oil mouth.This design makes clutch counter balance pocket draining more rapid, improves speed of response when clutch engages.
As can be seen from the contrast of conventional planetary frame frame and planet carrier of the present utility model, planet carrier size of the present utility model is less, degree of integration is higher, oil circuit distribution is simultaneously more reasonable, ensure mechanism's sufficient lubrication cooling, improve product working life, assembly size is less, more multi-platform vehicle can be suitable for arrange, also can realize more multi-platform general, need not redesign oil circuit, so many money vehicle is general simultaneously, also significantly can reduce costs, more be conducive to hybrid power system and to unify the universal of automatic transmission case and promoting.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
