Abstract
The utility model discloses an electric supercharger, comprising an impeller driven by a motor; the impeller, corresponding to an exhaust port of an impeller chamber, is connected with an air inlet of an engine; and the air inlet is communicated with air. The electric supercharger provided by the scheme does not use the waste gas of the engine so as to supply air to the engine stably and reliably.
Description
Technical field
The utility model relates to a kind of electric booster.
Background technique
For efficient and the output power that improves hot machine, the suction port at motor is provided with the pressure air inlet system usually, to improve suction pressure and density.Along with people to improving constantly that engine performance requires, turbosupercharger will be by more applications on motor.
Simple explanation, use and maintenance about turbosupercharger have been done comparatively detailed explanation in " automobile fashion newspaper " (09.443 phase), said turbosupercharger comprises two chambers, one is turbine chamber, another is a blade wheel chamber, corresponding turbine lotus leaf is taken turns coaxial setting, wherein the suction port of turbine chamber links to each other with exhaust opening of engine, rotates by exhaust gas-driven turbine, thereby has also driven the rotation of impeller; The relief opening of blade wheel chamber links to each other with the suction port of motor, forms a device that is similar to centrifugal blower supercharging is carried out in air inlet.Though this turbosupercharger has been utilized the waste gas energy of motor, also exists problems, the usage requirement that at first is this pressurized machine in use is subjected to a lot of restrictions than higher, and cold machine starts and can not open the throttle immediately, and it is lubricated to carry out preheating earlier.Hot machine can not stop working immediately, cool off, and utilizes machine oil to the lubricated cooling of turbine shaft.In addition, turbosupercharger precision is higher, and corresponding maintenance requirement is also high, because the lubricated of it is lean on engine motor oil lubricated, higher to the quality requirements of machine oil, in case break down, the loss meeting of machine oil increases greatly.
In addition, the pressure of waste gas is depended in the supercharging of turbosupercharger, can have a hysteresis, just has only the air displacement of waste gas to increase, and the exhaust effect of turbosupercharger just can corresponding raising.Therefore, occur the scheme of the electric turbine pressurized machine of built-in motor in turbosupercharger at present, but can't solve the high and unsettled intrinsic problem of exhaust of engine exhaust temperature.Further, motor just as mentioned above row temperature is very high, is easy to make the temperature of turbosupercharger to be higher than the temperature of lubricant oil good lubrication, therefore, toward contact air-cooling apparatus need be set on some turbosupercharger.
Summary of the invention
Therefore, the utility model provides a kind of electric booster that does not use engine exhaust at the above-mentioned defective of prior art, with reliable and stable to the motor air supply.
The technical solution adopted in the utility model is:
The utility model electric booster, it comprises one by motor-driven impeller, and the relief opening of the corresponding blade wheel chamber of this impeller links to each other with the suction port of motor, and suction port leads to atmosphere.
According to the electric booster of this city model utility technological scheme, do not re-use engine exhaust as power resources, and directly adopt the air inlet of motor-driven impeller supply engine.Thereby, can consider the start and stop of motor, and also can not produce the problem that air intake pressurized lags behind.
On the other hand, owing to needn't consider the temperature effect of waste gas, lubricating of this electric booster just can be adopted conventional grease lubrication mode so, can make the smaller volume of this electric booster, reduced turbine chamber than present pressurized machine, its compact structure is convenient to install in addition.What can further consider is, owing to needn't consider the influence of exhaust gas temperature, the housing of this electric booster can adopt the lower plastics of price so, and does not have all very high problem of design and manufacture cost as cast iron manufacturing, blade wheel chamber's employing aluminum alloy manufacturing are adopted in existing turbocharger turbine chamber.
Above-mentioned electric booster, the axle of described motor links to each other by a speed reducer with the gearbox output shaft of motor, and this speed reducer is connected for surmounting coupling with described between centers.
The above-mentioned electronic device that increases, described motor is the double-speed motor of 12V or 24V.
Description of drawings
Fig. 1 is the structural representation of electric booster among the utility model embodiment.
Among the figure: 1, relief opening, 2, motor, 3, axle, 4, suction port, 5, blade wheel chamber.
Embodiment
With reference to explanation accompanying drawing 1, the present embodiment electric booster, it comprises an impeller that is driven by motor 2, the relief opening 1 of the corresponding blade wheel chamber of this impeller links to each other with the suction port of motor, suction port 4 logical atmosphere.
Usually, motor needs the air inlet of certain pressure and flow, and the existing wheel speed that obtains by exhaust-driven turbine is difficult to reach requirement, and motor then can adopt high-revolving motor as required, and flexibility is than higher.Nature, employed motor all is a direct current generator on the motor, therefore, its speed governing mainly by the motor logarithm of coil, can be selected how fast direct current generator as required.Here, the double-speed motor of preferred 12V or 24V.What mainly consider is the unsuitable busy shift of motor, and under motor speed change continually varying situation, it is not fine requiring for the air inlet of high flow, and helps the abundant burning of fuel under the low speed situation.
Further, this programme has a mind to adopt other driving mode, and example is that the axle 3 of described motor links to each other by a speed reducer with the gearbox output shaft of motor, and this speed reducer is connected for surmounting coupling with described between centers.Do not using under the motor-driven situation like this, use the output shaft of engine gearbox to drive, and the rotating speed of this driving mode and output shaft coupling is being convenient to obtain to follow preferably effect.Why increasing a retarder, purpose is to make impeller to obtain relative high rotational speed.If can't satisfy the use needs by this driving mode, the driving that can adopt motor to replenish, and the existence that surmounts coupling can not influence the proper functioning of above-mentioned two gear-boxes.
Claims (3)
1. an electric booster is characterized in that it comprises an impeller that is driven by motor (2), and the relief opening (1) of the corresponding blade wheel chamber of this impeller links to each other with the suction port of motor, and suction port (4) leads to atmosphere.
