Description
Technical field
This utility model relates to automotive transmission technical field, particularly a kind of transmission oil pump end cap.
Background technology
Transmission oil pump is for being transported to transmission oil in the variator of motor vehicles or carrying speed change in this variator
Device oil.
Variator lubricating oil pump is used to make engine oil pressure raise and ensure certain oil mass, forces fuel feeding to each friction surface
Component, most common of which is rotor engine oil pump.The rotor engine oil pump used at present, including oil pump casing, lubricating oil pump
Lid, oil sealing and inner and outer Rotator, internal rotor actively and driven outer rotor are all contained in oil pump casing, on the perisporium of internal rotor
Being provided with outer double wedge, the inwall of outer rotor is provided with interior double wedge, the tooth of the outer double wedge of the gear ratio internal rotor of the interior double wedge of outer rotor
Many one of number, the fit depressions between outer double wedge and the interior double wedge of outer rotor of internal rotor, make to be linear contact between the flank of tooth,
Just defining multiple working chamber between the inner and outer Rotator gear teeth, internal rotor central shaft hole is fixed on driving shaft, by internal rotor band
When moving the rotating in same direction of outer rotor, owing to the rotating speed of internal rotor is more than the rotating speed of outer rotor, when rotor is disengaged, volume is gradually
Increasing, produce vacuum, suck lubricating oil, be further continued for rotating, when rotor is progressively engaged, oil pocket volume is gradually reduced, and oil is compressed,
Just lubricating oil is extruded.
Due to the Structure Designing Problem of the transmission oil pump of prior art, the suction of transmission oil pump inner engine oil and discharge are not
Freely, and enter the machine oil in transmission oil pump easily by higher-pressure region permeability, easily make transmission oil pump produce blocking and turn
Move the ill effects such as the most smooth.
Summary of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, it is provided that a kind of transmission oil pump end cap.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme:
A kind of transmission oil pump end cap, including the lid matched with oil pump body, lid is provided with some bolts hole, described
Lid side is provided with handle, and the end of handle is provided with bolt hole, is provided with oil duct in described handle, and the lower surface, end of handle is provided with and oil duct one
The fuel feed hole of end connection, described lid lower surface is provided with the first arc groove and the second arc groove, described first arc groove
Connecting with the oil duct other end, described second arc-shaped groove bottom is provided with the oil outlet running through lid.
Further, described lid upper surface is provided with strengthening rib strip.
Preferably, the bolt hole on lid is at least provided with 4.
Compared with prior art, the lower surface of oil pump end cap of the present utility model arranges the first arc groove and the second arc
Groove, the first arc groove connects with the oil duct other end in handle, and the second arc-shaped groove bottom is provided with the oil outlet running through lid,
End cap of the present utility model ensure that the oil-feed of oil pump and fuel-displaced smooth and easy, is not easily blocked.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model；
Fig. 2 is structure schematic diagram of the present utility model；
Fig. 3 is the B-B sectional view of handle in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by specific embodiment, in the signal of this utility model
Property embodiment and explanation be used for explaining this utility model, but be not intended as restriction of the present utility model.
A kind of transmission oil pump end cap as shown in Figure 1, Figure 2, Figure 3 shows, including the lid 1 matched with oil pump body, lid 1
Being provided with 4 bolts hole 2, described lid 1 side is provided with handle 3, and the end of handle 3 is provided with 2 bolts hole 2, is provided with oil in described handle 3
Road 4, the lower surface, end of handle 3 is provided with the fuel feed hole 6 connected with oil duct 4 one end, and it is recessed that described lid 1 lower surface is provided with the first arc
Groove 7 and the second arc groove 8, described first arc groove 7 connects with oil duct 4 other end, sets bottom described second arc groove 8
There is the oil outlet 5 running through lid.
Further, in order to increase the bulk strength of lid 1, described lid 1 upper surface is provided with strengthening rib strip 9.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, within each falling within protection domain of the present utility model.
