In the description of the utility model, it is to be understood that the orientation of the instruction such as term " interior ", " outer " or position are closed It is to be described based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplifying, rather than Indicate or imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore cannot It is interpreted as the limitation to the utility model.
In addition, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be mechanically connecting or being electrically connected Connect or the connection inside two elements, can be directly connected, can also be indirectly connected by intermediary, for For those of ordinary skill in the art, the concrete meaning of the term can be understood as the case may be.
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further Explanation, the content that embodiment refers to not is restriction to the utility model.
As shown in Figure 1, a kind of transmission oil pump, including integrally formed pump case 1, the pump case 1 is interior to be equipped with independently of each other High pressure rotor chamber 2 and low pressure rotor chamber 3, the pump case 1 is equipped with the low pressure oil oil inlet 3a, low of connection low pressure rotor chamber 3 Pressure oil oil discharge outlet 3b, the pump case 1 are equipped with high pressure oil oil inlet 2a, the high pressure oil oil discharge outlet 2b of connection high pressure rotor chamber 2, institute To state and dismountable high pressure pump cover 4 and low pressure pump cover 5 are additionally provided with pump case 1, the high pressure pump cover 4 is installed on outside high pressure rotor chamber 2, The low pressure pump cover 5 is installed on outside low pressure rotor chamber 3, and high pressure rotor component 6, the low pressure are equipped with the high pressure rotor chamber 2 3 are equipped with low pressure rotor component 7 in rotor chamber, and the high pressure rotor component 6 includes the first rotating shaft 6a being arranged in parallel and second turn Pitch wheel group, the low pressure rotor group are detachably installed on axis 6b, the first rotating shaft 6a and the second shaft 6b Part 7 includes the 3rd shaft 7a, the internal rotor on the 3rd shaft 7a and the outer rotor engaged with internal rotor, and the described 3rd Shaft 7a and first rotating shaft 6a are coaxially connected by a sleeve.
Above-mentioned technical proposal, which provides one kind, can be used only a motor-driven transmission oil pump of driving, the oil pump solution The problem of prior art of having determined needs to be equipped with two oil pumps to work independently when doing transmission design, and above-mentioned oil pump structure is tight Gather, be readily disassembled, the rotor in any one rotor chamber breaks down can independently dismount and repaired, and is worth mentioning the most It is that two oil pump coaxial designs can also bring a benefit, especially for speed change.
Further, the low pressure oil oil discharge outlet 3b sides of the low pressure rotor chamber 3 offer triangular groove 9.
In order to reduce the running noise during low pressure rotor oil extraction in low pressure rotor chamber 3, the utility model is arranged in low pressure oil The side of hydraulic fluid port 3b has opened up the groove 9 of triangle, and the effect for pressure of gradually releasing during oil extraction can be realized by changing groove 9, Greatly reduce the noise brought during oil extraction because of pressure oscillation and vibrations.
Further, the low pressure oil oil inlet 3a sides of the low pressure rotor chamber 3 are M types opening 10.
The characteristics of in view of low pressure rotor component in low pressure rotor chamber 3, inventor is by the side of low pressure oil oil inlet 3a M shapes are designed to, certainly it should be noted that M shapes opening should be preferably capable of pair started with two internal rotors, outer rotors Answer the shape that tooth position engages identical, also can be realized as the feelings that M shapes opening 10 expands oil inlet volume to the full extent just Under condition also with internal rotor and the marginal lines matching engaged of outer rotor, that is to say, that the effective area of oil inlet increases, and interior The time of rotor and the formation sealed volume chamber of outer rotor engagement does not but shorten the oil inlet time, this is obviously favourable without in advance In the volumetric efficiency for improving whole low pressure rotor pump.
