Description
Technical field
The present invention relates to engine art, more particularly to a kind of diesel engine steering pump.
Background technology
It is the device of vehicle hydraulic system delivery hydraulic pressure oil that the steering pump of diesel engine is.
Caulking gum part inside existing steering pump is generally fluorubber, and it is -20 DEG C~200 that fluorubber adapts to operating temperature
DEG C so that steering pump under less than -20 DEG C of temperature working environments, because of the failure of its caulking gum part, causes to turn to pump work for a long time
Efficiency declines even failure.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the invention, without answering
In being considered as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of simple and reasonable diesel engine steering pump, inside the diesel engine steering pump
Rubber seal material use ethylene acrylate rubber, reliable and stable work at low ambient temperatures can be kept.In addition, rubber
Seal is laid in off-load oil duct both sides, the energy heats that can be produced by off-load, further increases it in low temperature environment
The reliability of lower work.
To achieve the above object, the invention provides a kind of diesel engine steering pump, including：Low pressure oil pocket, it is located at the bavin
The front end of oil machine steering pump inner chamber, and correspondence offers oil inlet；High-voltage oil cavity, after it is located at the diesel engine steering pump inner chamber
End, correspondence offers oil-out, and is connected with the oil-out by oil duct；And first rubber seal and the second rubber it is close
Sealing, it uses ethylene acrylate rubber, the both sides of the oil duct is arranged in, to seal the high-voltage oil cavity and low pressure
Oil pocket.
Preferably, in above-mentioned technical proposal, oil-out is located at the rear end of the diesel engine steering pump inner chamber.
Preferably, in above-mentioned technical proposal, the first rubber seal and the second rubber seal are O-ring seal.
Compared with prior art, the present invention has the advantages that：Rubber seal inside the diesel engine steering pump
Material uses ethylene acrylate rubber, can keep reliable and stable work at low ambient temperatures.In addition, rubber seal is laid in
Off-load oil duct both sides, the energy heats that can be produced by off-load, further increase its reliability for working at low ambient temperatures
Property.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of diesel engine steering pump of the invention.
Fig. 2 is the dimensional structure diagram of diesel engine steering pump of the invention.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is described in detail, it is to be understood that guarantor of the invention
Shield scope is not limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
As depicted in figs. 1 and 2, the diesel engine steering pump according to the specific embodiment of the invention disclosure satisfy that -20 DEG C with
Under working environment reliably working.The diesel engine steering pump is specifically included：High-voltage oil cavity 2, low pressure oil pocket 5, oil duct 3, first
The rubber seal 4 of rubber seal 1 and second, wherein, low pressure oil pocket 5 is located at the front end of the diesel engine steering pump inner chamber, and right
Oil inlet 6 should be offered.High-voltage oil cavity 2 is located at the rear end of the diesel engine steering pump inner chamber, and is connected with oil-out 7 by oil duct 3
Logical, oil-out 7 is located at the rear end of the diesel engine steering pump inner chamber.The high pressure liquid force feed of high-voltage oil cavity 2 after the off-load of oil duct 3 by leading to
Oil-out 7 is crossed to export.First rubber seal 1 and the second rubber seal 4 use ethylene acrylate rubber, are arranged in oil
The both sides in road 3, to seal high-voltage oil cavity 2 and low pressure oil pocket 5.Rubber seal material inside the diesel engine steering pump uses second
Alkene acrylic rubber, can keep reliable and stable work at low ambient temperatures.In addition, rubber seal is laid in off-load oil duct two
Side, the energy heats that can be produced by off-load, further increases its reliability for working at low ambient temperatures.
Specifically, low pressure oil pocket 5 is located at the front end of the diesel engine steering pump inner chamber, and correspondence offers oil inlet 6.Liquid
Force feed enters the outputs to be pressurised such as low pressure oil pocket 5 by oil inlet 6.
High-voltage oil cavity 2 is located at the rear end of the diesel engine steering pump inner chamber, and correspondence offers oil-out 7, and by oil duct 3 with
The oil-out 7 is connected, and oil-out 7 is located at the rear end of the diesel engine steering pump inner chamber.The high pressure liquid force feed of high-voltage oil cavity 2 is by oil
Exported by oil-out 7 after the off-load of road 3.
First rubber seal 1 and the second rubber seal 4 use AEM (ethylene acrylate rubber), are arranged in
The both sides of oil duct 3, to seal high-voltage oil cavity 2 and low pressure oil pocket 5.On the one hand, the first rubber seal 1 and the second rubber seal
4 can keep reliable and stable work at low ambient temperatures using ethylene acrylate rubber.On the other hand, the first rubber seal 1
With the both sides that the second rubber seal 4 is arranged in oil duct 3, the heat of the high pressure liquid force feed generation of the load high pressure oil pocket 2 of oil duct 3
Amount can be heated to the first rubber seal 1 and the second rubber seal 4, further increase what it worked at low ambient temperatures
Reliability.Preferably, the first rubber seal 1 and the second rubber seal 4 are O-ring seal.
To sum up, the rubber seal material inside the diesel engine steering pump uses ethylene acrylate rubber, can be maintained at
Reliable and stable work under low temperature environment.In addition, rubber seal is laid in off-load oil duct both sides, the heat that can be produced by off-load
Can heat, further increase its reliability for working at low ambient temperatures.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
