Abstract
The present invention provides the oil pumps that one kind can prevent rotor from inverting, including the pump housing, pump cover, driving shaft, transmission gear, the driving shaft is installed in rotation in the axis hole of the pump housing and pump cover, one one-way clutch is installed, the transmission gear is mounted on driving shaft by the one-way clutch in the axis hole of the transmission gear.In above-mentioned technical proposal, due to not changing the oil piping system of gearbox and oil pump, under the premise of keeping oil pump internal structure constant, only increase an one-way clutch, when motor reversal (reversing) can be realized, oily air pump inoperative in the axis hole of transmission gear.
Description
Technical field
The invention belongs to lubrication technical field, in particular to a kind of oil pump.
Background technique
When gear box oil pump and lubricating oil pump are used for fuel oil vehicle, due to a rotation always direction for engine, so oily
The movement of pump is also in one direction always.And for motor-driven vehicle, since motor itself can be with positive and negative rotation, oil
Pump there is the problem of may inverting.Current oil pump structure and gearbox body oil piping system does not make a change on oil circuit,
So when oil pump reversion, oil pump cannot normal suction oil, the case where having dry wear generation, prolonged reversion operation can shadow
Ring the service life of oil pump and the service performance of automobile.In the design of vehicle, when motor reversal namely the reversing the case where
Under, mechanical oil pump does not need work, separately has an electric oil pump that can provide lubrication.
Summary of the invention
The technical problem to be solved in the present invention is to provide the oil pumps that one kind can prevent rotor from inverting.
In order to solve the above-mentioned technical problem, the technical scheme is that a kind of oil pump that can prevent rotor from inverting, packet
The pump housing, pump cover, driving shaft, transmission gear are included, the driving shaft is installed in rotation in the axis hole of the pump housing and pump cover, the biography
Moving gear is mounted on one end of driving shaft, and an one-way clutch, the driving cog are equipped in the axis hole of the transmission gear
Wheel is mounted on driving shaft by the one-way clutch.
Further, the position on the driving shaft on the outside of transmission gear is equipped with retaining ring.
Further, the driving shaft is equipped with the oil duct for being connected to oil pocket and one-way clutch.
Further, the oil duct includes the oil duct and a plurality of radial oil duct of an axial direction.
In above-mentioned technical proposal, due to not changing the oil piping system of gearbox and oil pump, oil pump internal structure is being kept not
Under the premise of change, only increase an one-way clutch in the axis hole of transmission gear, when motor reversal (reversing) can be realized,
Oily air pump inoperative.
Detailed description of the invention
Fig. 1 is the oil pump structure schematic diagram in the embodiment of the present invention；
Appended drawing reference are as follows:
1 --- the pump housing 2 --- pump cover 3 --- driving shaft
4 --- transmission gear 5 --- one-way clutch 6 --- retaining rings
7 --- oil duct.
Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.
In the description of the present invention, it is to be understood that, term " first ", " second " are used for description purposes only, and cannot
It is interpreted as indication or suggestion relative importance or implicitly indicates the quantity of indicated technical characteristic.In description of the invention
In, the meaning of " plurality " is two or more, unless otherwise specifically defined.In the description of the present invention, it needs
Illustrate, unless otherwise specified and limited, term " installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be
Mechanical connection or electrical connection, the connection being also possible to inside two elements can be directly connected, and can also pass through intermediary
It is indirectly connected, for the ordinary skill in the art, can understand the concrete meaning of the term as the case may be.
As shown in Figure 1, the preferred embodiment of the present invention is: the oil pump that one kind can prevent rotor from inverting, including the pump housing 1,
Pump cover 2, driving shaft 3, transmission gear 4, driving shaft 3 are installed in rotation in the axis hole of the pump housing 1 and pump cover 2, and transmission gear 4 is pacified
One one-way clutch 5 is installed in an interference fit mounted in one end of driving shaft 3, in the axis hole of transmission gear 4, is driven
Gear 4 is mounted on driving shaft 3 by the one-way clutch 5, and the position on driving shaft on the outside of transmission gear is also installed
There is retaining ring 6, for blocking transmission gear 4 and one-way clutch 5.
In order to provide lubrication and heat dissipation to one-way clutch 5, driving shaft 3 is equipped with for being connected to oil pocket and one-way clutch 5
Oil duct 7, the oil duct and a plurality of radial oil duct of the oil duct 7 an including axial direction.
In above-mentioned technical proposal, due to not changing the oil piping system of gearbox and oil pump, oil pump internal structure is being kept not
Under the premise of change, only in the axis hole of transmission gear 4 increase an one-way clutch 5, can be realized motor reversal (
Vehicle) when, oily air pump inoperative.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart from the technical program design under the premise of it is any obviously replace it is within the scope of the present invention.
In order to allow those of ordinary skill in the art more easily to understand the improvements of the present invention compared with the existing technology, this
Some attached drawings of invention and description have been simplified, and for the sake of clarity, present specification is omitted some other members
Element, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the contents of the present invention.
