CG engines also widely use on tricycle at present, with the exploitation of oil-cooling engine, oil-cooling engine Power is increasing, and oil-cooling engine needs oil mass also increasing, and CG engine oil pumps traditional at present have pump oil amount The problem of insufficient, if the pump low on fuel of engine oil pump, meeting and cause that engine temperature is high, engine component is because of coming oil Slowly wear, it is impossible to meet requirement.CG engine oil pumps traditional at present are limited by mounting hole, can not be by internal Outer rotor external diameter is increased to improve the pump oil amount of lubricating oil pump.
The content of the invention
For deficiencies of the prior art, it is an object of the invention to propose a kind of motorcycle engine oil pump Assembly, this motorcycle engine oil pump assembly do not influence to install and use while pump oil amount is increased.
To achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of motorcycle engine oil pump assembly, including pump case, outer rotor, internal rotor, pump shaft, end cap and driven gear;Institute Stating pump case has the pump case inner chamber of cylinder, and the outer rotor is adapted with the pump case inner chamber, the internal rotor and outer rotor It is adapted and is arranged in the pump case inner chamber, the end cap is fixed by screws in pump case one end and turns internal rotor with outer Son is enclosed in pump case inner chamber, and the pump shaft is connected through internal rotor and outer rotor and one end with end cap, and the pump shaft other end passes The pump case other end, the driven gear are fixed on the pump shaft of the pump case other end, the driven gear both ends of the surface near pump shaft To pump shaft other end projection and cavity is formed in nearly pump case side, the pump case other end is extended in the cavity.
In this motorcycle engine oil pump assembly, on the premise of the position of the driven gear gear teeth is not changed, in pump case Chamber, internal rotor and outer rotor correspondingly extend with pump case vertically, do not influence to install while pump oil amount is increased and make With.
Further, the side of the nearly pump case other end in pump case inner chamber of the present invention, the one of the nearly pump case other end of internal rotor Side and the side of the nearly pump case other end of outer rotor are axially extended to the cavity.
Further, driven gear radial section of the present invention is in " several " font.
Further, driven gear of the present invention uses plastic material.
Further, it is provided with driven gear of the present invention and driven gear shape identical metal insert.
Compared with prior art, the beneficial effects are mainly as follows:
1st, driven gear is designed as " several " font by this motorcycle engine oil pump assembly, is not changing driven gear wheel tooth position In the case of putting, other positions of driven gear are raised to the pump shaft other end, and correspondingly the length of internal rotor and outer rotor can be with Increase and the cavity that is formed after raised in, after internal rotor and outer rotor length increase, while pump oil amount is increased not Influence installation and use;
2nd, oil pump driven gear is embedded with the metal insert consistent with gear shape, and the intensity of gear is high.
Brief description of the drawings

In accompanying drawing, 1- pump cases;2- outer rotors;3- internal rotors;4- pump shafts;5- end caps;6- driven gears;7- screws;
51- fuel feed holes;52- oil outlets;53- end cap installing holes;54- engine oil pump assembly positioning holes;61- gear inserts.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
As shown in figure 3, the motorcycle engine oil pump assembly of the present embodiment, including pump case 1, outer rotor 2, internal rotor 3, Pump shaft 4, end cap 5 and driven gear 6;The pump case 1 has a pump case inner chamber of cylinder, in the outer rotor 2 and the pump case Chamber is adapted, and the internal rotor 3 and outer rotor 2 are adapted and be arranged in the pump case inner chamber, and the end cap 5 passes through screw 7 are fixed on pump case one end and internal rotor 3 and outer rotor 2 are enclosed in pump case inner chamber, and the pump shaft 4 is through internal rotor 3 and outside Rotor 2 and one end is connected with end cap 5, the other end of pump shaft 4 passes the pump case other end, and the driven gear 6 is fixed on against pump case 1 On the pump shaft 4 of the other end, the driven gear both ends of the surface near pump shaft 4 are raised to the pump shaft other end and formed in the nearly side of pump case 1 Cavity, the pump case other end are extended in the cavity.It is the side of the nearly pump case other end in pump case inner chamber, interior in the present embodiment The side of the nearly pump case other end of rotor 3 and the side of the nearly pump case other end of outer rotor 2 are axially extended to the cavity.
