Abstract
The utility model provides a kind of oil pump that 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 utility model 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.
Utility model content
The technical problem to be solved by 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 solution of the utility model is: the oil that one kind can prevent rotor from inverting
Pump, including the pump housing, pump cover, driving shaft, transmission gear, the driving shaft are installed in rotation in the axis hole of the pump housing and pump cover,
The transmission gear is mounted on one end of driving shaft, and an one-way clutch is equipped in the axis hole of the transmission gear, described
Transmission gear 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 utility model embodiment；
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 utility model is made below with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.
In the description of the present invention, it should be understood that term " first ", " second " are used for description purposes only, and
It cannot be understood as indicating or implying relative importance or implicitly indicate the quantity of indicated technical characteristic.In the utility model
Description in, the meaning of " plurality " is two or more, unless otherwise specifically defined.In retouching for the utility model
In stating, it should be noted that unless otherwise specified and limited, term " installation ", " connected ", " connection " shall be understood in a broad sense, example
Such as, mechanical connection or electrical connection be can be, the connection being also possible to inside two elements can be directly connected, and can also lead to
It crosses intermediary to be indirectly connected, for the ordinary skill in the art, can understand the term as the case may be
Concrete meaning.
As shown in Figure 1, the preferred embodiment of the utility model is: the oil pump that one kind can prevent rotor from inverting, including pump
Body 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, driving cog
Wheel 4 is mounted on one end of driving shaft 3, is equipped with an one-way clutch in an interference fit in the axis hole of transmission gear 4
5, transmission gear 4 is mounted on driving shaft 3 by the one-way clutch 5, the position on driving shaft on the outside of transmission gear
It is also equipped with 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 utility model, and in addition to this, the utility model can be with other sides
Formula realizes that any obvious replacement is in the protection model of the utility model under the premise of not departing from the technical program design
Within enclosing.
In order to allow those of ordinary skill in the art more easily understand the improvement of the utility model compared with the existing technology it
Place, some attached drawings of the utility model and description have been simplified, and for the sake of clarity, present specification is omitted one
A little other elements, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the interior of the utility model
Hold.
