For achieving the above object, the utility model provides motor dry sump system, comprise: dry sump, it comprises: dry sump body, and the oil trap and the external oil pump interface that is opened in this dry sump body side, the inner of described external oil pump interface and oil sump that are opened in this dry sump body bottom; Fuel reserve tank, it is arranged on external engine; External oil pump, it is arranged on engine crankcase outside, and is connected with fuel reserve tank with the external oil pump interface of described dry sump respectively by lubricating oil pipeline; And built-in oil pump, it is laid in the inside of engine crankcase, and is connected with described fuel reserve tank by lubricating oil pipeline.
Preferably, in technique scheme, oil trap is two.
Preferably, in technique scheme, external oil pump interface is two, the inner of each external oil pump interface all with two oil sump.
Preferably, in technique scheme, external oil pump is two, respectively with two corresponding connections of external oil pump interface, forms the external oil pump of two-stage and pumps structure.
Preferably, in technique scheme, built-in oil pump is in transmission connection by idle gear and the external oil pump carrying.
Preferably, in technique scheme, it is more than 2 times or 2 times that the flow of external oil pump is built-in oil pump.
Compared with prior art, the utlity model has following beneficial effect: this motor dry sump system is by being improved to wet sump system the dry sump system that fuel reserve tank is arranged on external engine and interior external oil pump, thereby reduced the whole height of motor, improved the suitability of motor at small space; Avoid the vehicle travelling under severe road conditions because motor tilts to cause lubricant oil, to inhale sky, make friction pair oil starvation cause motor damage even to be scrapped simultaneously, thereby strengthened the rideability of the cross-country ability, particularly various precipitous road surfaces of vehicle.In addition, dry sump is more pipeline and fuel reserve tank because lubricant oil has passed through, and in this process, lubricant oil has obtained coolingly more fully, has reduced the temperature of lubricant oil, the life-span of having improved lubricant oil.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Unless separately there is other clearly to represent, otherwise in whole specification and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or constituent element, and do not get rid of other element or other constituent element.
(arrow represents that lubricant oil flows to) as shown in Figure 2, according to the concrete structure of the motor dry sump system of the utility model embodiment, comprise: dry sump 21, external oil pump 22, fuel reserve tank 23 and built-in oil pump 24, wherein, dry sump 21 is laid in the bottom of engine crankcase; Fuel reserve tank 23 is arranged on motor 25 outsides; External oil pump 22 is arranged on engine crankcase outside, and is connected with fuel reserve tank 23 with dry sump 21 respectively by lubricating oil pipeline; Built-in oil pump 24 is laid in the inside of engine crankcase 25, and be connected with fuel reserve tank 23 by lubricating oil pipeline, by being stored in lubricant oil in fuel reserve tank 23, pump to that motor need to lubricate or cooling position, after lubricated or cooling completing, effect due to gravity, lubricant oil is got back to the dry sump 21 that is positioned at engine bottom again, then by external oil pump 22, the lubricant oil of dry sump 21 collections is pumped to fuel reserve tank 23, completes whole circulation.On the basis of original motor wet sump system, to set up external oil pump 22, fuel reserve tank 23 and associated pipe, and wet sump is replaced by dry sump 21, motor becomes dry sump system.Only, through simply increasing or reduce relevant component, motor can switch between dry sump and wet sump, has increased the suitability of motor.
Wherein, as shown in Figure 3 and Figure 4, dry sump 21 comprises: dry sump body 26, and the oil trap 27 and the external oil pump interface 28 that is opened in these dry sump body 26 sides that are opened in these dry sump body 26 bottoms, on oil trap 27, be covered with the cover plate 29 with sieve aperture 31.Oil trap 27 is two, after being respectively used to collect lubricated or cooling completing, because the lubricant oil of engine bottom front and back side is got back in the effect of gravity again; The bottom of two oil traps 27 also offers respectively drain tap.External oil pump interface 28 is two, and the inner is communicated with two oil traps 27 respectively, and outer end is for being connected with external oil pump 22 by lubricating oil pipeline, so that the lubricant oil in the oil trap of dry sump 21 27 is pumped to fuel reserve tank 23.Also be two with the external oil pump 22 of two corresponding connections of external oil pump interface 28, form the external oil pump of two-stage and pump structure.Lubricated or cooled lubricant oil need to just can enter through the sieve aperture 28 of cover plate 29 oil trap 27 circulations, and sieve aperture 28 can be eliminated the bubble in lubricant oil, to increase its cycle efficiency and quality.
As shown in Figure 5, built-in oil pump 24 is laid in the inside of engine crankcase, and is connected with fuel reserve tank 23 by lubricating oil pipeline, by being stored in lubricant oil in fuel reserve tank 23, pumps to that motor need to lubricate or cooling position.Built-in oil pump 24 is in transmission connection with external oil pump 22 by the idle gear 30 carrying, and the flow of external oil pump 22 is the more than 2 times or 2 times of built-in oil pump 24.
To sum up, this motor dry sump system is by being improved to wet sump system the dry sump system that fuel reserve tank is arranged on external engine and interior external oil pump, thereby reduced the whole height of motor, improved the suitability of motor at small space; Avoid the vehicle travelling under severe road conditions because motor tilts to cause lubricant oil, to inhale sky, make friction pair oil starvation cause motor damage even to be scrapped simultaneously, thereby strengthened the rideability of the cross-country ability, particularly various precipitous road surfaces of vehicle.In addition, dry sump is more pipeline and fuel reserve tank because lubricant oil has passed through, and in this process, lubricant oil has obtained coolingly more fully, has reduced the temperature of lubricant oil, the life-span of having improved lubricant oil.
