Abstract
An automobile-used vacuum pump is used for solving the problem of a vacuum source, and adopts the technical scheme that the vacuum pump adopts a simple-blade vacuum pump fixed on an engine cylinder lid; a driving shaft of the vacuum pump is butted with an engine camshaft; a vacuum booster interface is connected with a vacuum booster through a rubber tube; Through the improvement, a supercharger control valve interface in parallel connection with the vacuum booster interface is also arranged at the root of the vacuum booster interface, and is connected with a vacuum control valve of a supercharger through a rubber tube. With the supercharger control valve interface additionally arranged in the utility model, not only can the performance of a vacuum source of the vacuum booster of an automobile be improved, but also the supercharger control valve interface can be conveniently connected with a supercharger control valve, so that the vacuum pump is especially suitable for the use on vehicle equipped with diesel oil supercharged engines.
Description
Technical field
The utility model relates to a kind of employed vacuum pump of vehicle that disposes the diesel oil blow-fed engine, belongs to the fluid pump technical field.
Background technology
Vehicle vacuum pump is vacuum booster pump again, and it mainly acts on is that vacuum booster unit for brake system of car provides vacuum, alleviating the strength at repeated alternation of navigating mate, and guarantees that brake system of car can provide enough braking forces.When automobile adopted the diesel oil blow-fed engine, blwr also needed extra vacuum source to be controlled, but existing vehicle vacuum pump has only an admission port, can not satisfy the requirement of engine supercharger and car load vacuum booster unit simultaneously.
In addition, the channel for oiling more complicated of existing vehicle vacuum pump, generally lubricated by sebific duct, not only processing inconvenience, cost is higher, and sebific duct is aging easily, influences lubricant effect.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of requirement that can satisfy engine supercharger and car load vacuum booster unit simultaneously is provided, and channel for oiling is simple and reliable, the vehicle vacuum pump of being convenient to process.
The alleged problem of the utility model realizes with following technical proposals:
A kind of vehicle vacuum pump, described vacuum pump is single vane vacuum pump, it is fixed in engine cylinder and covers, its axle drive shaft docks with engine cam, the vacuum booster interface is connected with the vacuum booster unit of automobile by sebific duct, after the improvement, at the blwr control cock interface that the root of its vacuum booster interface also is provided with it and connects, described blwr control cock interface is connected to the vacuum control valve of blwr by sebific duct.
Above-mentioned vehicle vacuum pump, the interface of vacuum pump housing and engine cylinder cover is provided with the lubricating oil oil inlet, described oil inlet docks with the engine cylinder cover oil main line, and the pump chamber return opening and the air extractor duct of vacuum pump enter engine sump tank by the fuel return hole on the cylinder cap.
Above-mentioned vehicle vacuum pump is equipped with the O RunddichtringO between vacuum pump oil inlet and cylinder cap oil main line.
The utility model has been set up blwr control cock interface on the basis of conventional vacuum pump, can not only improve the vacuum source performance for the vacuum booster unit of automobile, can also be connected with the blwr control cock easily, be particularly suitable for disposing the vehicle use of diesel oil blow-fed engine.
Lubricating oil oil inlet of the present utility model directly docks with the oil main line that engine cylinder covers, and channel for oiling is simplified greatly, not only saves sebific duct, has reduced productive costs, and process and install very convenient, has improved the reliability of channel for oiling.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is vacuum pump and camshaft connection diagram;
Fig. 3 is a vacuum pump oil circuit scheme drawing;
Fig. 4 is the scheme of installation of vacuum pump.
Each label is among the figure: 1, camshaft; 2, axle drive shaft; 3, cylinder cap; 4, vacuum pump; 5, cylinder cap oil main line; 6, oil main line leads to vacuum pump outlet; 7, vacuum booster interface; 8, blwr control cock interface; 9, oil inlet; 10, fixed bolt hole; 11, pump chamber return opening and air extractor duct.
The specific embodiment
The utility model can provide vacuum for the vacuum booster of automobile and the blwr of driving engine as two vacuum sources simultaneously, and this vacuum pump channel for oiling is simple and reliable, is convenient to processing, and cost is lower.
Referring to Fig. 2, the utility model is single vane vacuum pump of camshaft actuated, and at groove of the end of camshaft 1 processing, the end shape of the axle drive shaft 2 of this groove and vacuum pump is complementary, and produces vacuum thereby drive the vacuum pump running.
Referring to Fig. 1, Fig. 3, one oil inlet 9 is arranged on the pump housing of vacuum pump, oil inlet 9 is connected with cylinder cap oil main line 5, between the O RunddichtringO is housed, when vacuum pump is worked, the lubricating oil pump of driving engine with oil pump in each oil duct, advance lubricated to each part of driving engine, enter vacuum pump by oil inlet 9 simultaneously, flow out from pump chamber oil return and air extractor duct 11 (both are mouths) after vacuum pump is lubricated, enter oil pan tray from the oil return of cylinder cap fuel return hole.Lubricated convenient and reliable, and easy to process to cylinder cap.
Referring to Fig. 1, Fig. 3, the utility model has been set up blwr control cock interface 8 at the check valve place, and blwr control cock interface 8 is connected to vacuum control valve by sebific duct, blwr is controlled, thereby reduced cost.
After being installed in camshaft 1 on the cylinder cap 3, at first vacuum pump axle drive shaft 2 is installed in the groove of camshaft 1, vacuum pump is fixed on the cylinder cap 3, blwr control cock interface 8 usefulness sebific ducts are connected to the vacuum control valve of blwr with fixed bolt hole 10.When engine operation, vacuum pump begins to produce vacuum under the driving of camshaft 1, because vacuum pump has two vacuum source interfaces, thereby can vacuum is provided for simultaneously blwr and vacuum booster.Lubricating oil enters in the oil main line 5 under the driving of lubricating oil pump, and enters in the vacuum pump oil inlet 9 towards vacuum pump outlet 6 by oil main line, guarantees the lubricated of vacuum pump.
