Abstract
The invention provides a pump cover of a speed changing box oil pump. An installing hole where a pressure releasing valve can be installed and which is communicated with the inner portion of the speed changing box oil pump is formed in the pump cover. According to the pump cover of the speed changing box, the pressure releasing valve is installed on the pump cover so as to replace the method that the pressure releasing valve is installed independently and then is communicated with the speed changing box oil pump, so that the pump cover and the pressure releasing valve are integrated. Therefore, a matched structure of the speed changing box oil pump and the pressure releasing valve is simplified, probability of occurrence of faults is lowered, pressure releasing operation is more convenient, and normal working of the speed changing box oil pump is guaranteed. The invention further provides the speed changing box oil pump with the pump cover.
Description
Technical field
The present invention relates to the hydraulic equipment technical field, more particularly, relate to a kind of pump cover of gear box oil pump, the invention still further relates to a kind of gear box oil pump with this pump cover.
Background technique
Automobile gearbox the time needs gear box oil pump constantly to charge into hydraulic oil to its inside in work, so that the gearbox inner member is played lubrication, and then guarantees the proper functioning of gearbox.
Gear box oil pump is the core component of gearbox lubrication system, and its structure generally comprises rotor drive shaft, internal rotor, external rotor, pump cover and the pump housing.Gear box oil pump is when work, and rotor drive shaft drives internal rotor and rotates, thereby to the gearbox fuel feeding.In this process; cause damage with the precision parts to pump housing inside for fear of the gear box oil pump internal oil pressure is bigger than normal; simultaneously also in order to reduce the big noise that oil pressure produces when bigger than normal; Decompression valves need be set independently, and (Decompression valves has another name called safety valve; it can be according to the working pressure automatic on-off of system, generally is installed on protective system safety on the equipment of locking system or the pipeline.When equipment or manifold pressure surpass the Decompression valves setting pressure; namely open pressure release automatically; assurance equipment and pipeline internal medium pressure are under setting pressure; protection equipment and pipeline; prevent accident) cooperate with gear box oil pump; carry out the pressure release operation so that oil pressure is bigger than normal in the pump housing, make oil pressure recover normal.
But for gear box oil pump disposes independently Decompression valves, feasible device structure is comparatively complicated, and the probability that breaks down is bigger.
Therefore, how simplifying the cooperating structure of gear box oil pump and Decompression valves, is present those skilled in the art's problem demanding prompt solution.
Summary of the invention
In view of this, the invention provides a kind of pump cover of gear box oil pump, it has simplified the cooperating structure of gear box oil pump and Decompression valves.The present invention also provides a kind of gear box oil pump with this pump cover.
In order to achieve the above object, the invention provides following technological scheme:
A kind of pump cover of gear box oil pump, wherein, described pump cover be provided with can install Decompression valves and with the mounting hole of the inside conducting of described gear box oil pump.
Preferably, in the pump cover of above-mentioned gear box oil pump, described mounting hole is by many oil transportation channels and described mounting hole conducting.
Preferably, in the pump cover of above-mentioned gear box oil pump, described mounting hole is near the outer side surface setting of described pump cover.
Based on the above-mentioned pump cover that provides, the present invention also provides a kind of gear box oil pump, comprises pump cover and the pump housing, and described pump cover is above-mentioned any described pump cover.
In the pump cover of gear box oil pump provided by the invention, it is provided with mounting hole, and this mounting hole can cooperate installation with Decompression valves, and with the inside conducting of gear box oil pump, the hydraulic oil of gear box oil pump inside can be derived by Decompression valves, and then realize the pressure release of gear box oil pump inside.The pump cover of gear box oil pump provided by the invention, Decompression valves is installed on the pump cover, to replace Decompression valves mode with the gear box oil pump conducting is set independently again, make pump cover and Decompression valves be integrated in one, thereby simplified the cooperating structure of gear box oil pump and Decompression valves, and then reduced the probability that fault occurs, and make pressure release more convenient to operate, guaranteed the proper functioning of gear box oil pump.The present invention also provides a kind of gear box oil pump with this pump cover.

Embodiment
The invention provides a kind of pump cover of gear box oil pump, it has simplified the cooperating structure of gear box oil pump and Decompression valves.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
As Fig. 1-shown in Figure 4, the pump cover of the gear box oil pump that the embodiment of the invention provides, wherein, pump cover 1 is provided with can install Decompression valves 4(as shown in Figure 4) and with the mounting hole 2 of the inside conducting of gear box oil pump.
In the pump cover of the gear box oil pump that present embodiment provides, it is provided with mounting hole 2, this mounting hole 2 can cooperate installation with Decompression valves 4, and the inside conducting of mounting hole 2 and gear box oil pump, the hydraulic oil of gear box oil pump inside can be derived by Decompression valves 4, and then realize the pressure release of gear box oil pump inside.
The pump cover of the gear box oil pump that present embodiment provides, Decompression valves 4 is installed on the pump cover 1, to replace the independent mode that arranges again with the gear box oil pump conducting of Decompression valves 4, make pump cover 1 and Decompression valves 4 be integrated in one, thereby simplified the cooperating structure of gear box oil pump and Decompression valves 4, and then reduced the probability that fault occurs, and make pressure release more convenient to operate, guaranteed the proper functioning of gear box oil pump.
