Description
Technical field
The invention belongs to technical field of automobile engine, and in particular to gasoline engine electric controlled turbocharger.
Background technique
Automobile engine waste gas turbine pressure boost device is to increase Induction air flow using the exhaust gas of engine, is substantially
Engine torque, power are promoted using exhaust energy.Currently, application of the turbocharging technology on gasoline engine is more and more wider
It is general, it has also become a kind of mainstream technology route.
After turbocharger becomes a kind of mainstream technology route, with the continuous of national fuel oil regulation plus sternly, to this
Booster is precisely controlled, and has been become more and more important and urgently.Meanwhile consumer wants the sound quality of turbocharger products
Ask also higher and higher, rather than just the reliability and high-performance level for resting on product.Therefore, traditional pneumatic actuator whirlpool
The problem of wheel booster is in terms of being precisely controlled with more high acoustic quality just seems more and more prominent, at this point, Electric Actuator turbine
Booster becomes as a kind of feasible solution, but certain challenge is proposed to arrangement space.
Chinese patent literature CN201620589292.1 discloses a kind of turbocharger, including compressor compressor, whirlpool
Turbine and Electric Actuator, pressure shell are connect by middleware with volute, and position Electric Actuator is fixed on pressure shell, described electronic
Actuator is connected to exhaust gas by-pass valve by push rod.In the patented technology, resonant cavity is not integrated with compressor, electronic execution
Device is arranged on the inside of booster, between booster and engine, is unfavorable for booster integral arrangement and lightweight.And electricity
Dynamic actuator push rod is directly connect with exhaust gas by-pass valve, and mechanical transmission noise is bigger, and there is also the skies of further structure optimization
Between.
Summary of the invention
The object of the present invention is to provide electric controlled turbocharger and arragement construction, which integrates resonant cavity, and will be electric
Dynamic actuator is arranged on the outside of booster, is further eliminated, is made by rotational noise of the damping pad to Electric Actuator
Supercharger structure is more compact, weight is lighter, is conducive to arrangement on the engine, and noise and vibration are smaller.
Technical scheme is as follows:
A kind of electric controlled turbocharger, including compressor, turbine, intermediate and Electric Actuator.During the compressor passes through
Mesosome connects turbine.Resonant cavity, the shell one of the resonant cavity and compressor are integrated in the outlet outer fix of compressor
Change is cast；Electric Actuator is arranged on the outside of booster, and the output end of Electric Actuator passes through connecting rod and turbine
The connection of exhaust gas bypass mechanism.
The present invention designs using the above structure, and cavity resonator structure is integrated in supercharger air compressor outlet, can make to arrange
Structure is more compact, and effectively reduces the pneumatic noise of compressor.Simultaneously as Electric Actuator is than traditional pneumatic actuator
Structure is bigger, is arranged on the outside of booster, can effectively shorten supercharger volute entrance length, keeps supercharger structure tighter
Gather, weight it is lighter, to be more advantageous to the arrangement of booster on the engine.
Further, the connecting portion in the connecting rod end of Electric Actuator and turbine is equipped with damping pad.Vibration damping
The application of gasket can effectively inhibit actuator caused by engine impulse pressure to tap abnormal sound, reduce vibration and noise.
Further, there is through-hole among the damping pad, the inner periphery in hole is disposed with multiple elastic fins, can increase and subtract
The effectiveness in vibration suppression of vibration gasket.Elastic fin is especially designed as T-type structure, the top surface of T word is towards gasket center, height one
It causes, T-type structure can more effectively absorb vibration, noise-decreasing in vibrated impact.
Present invention further propose that a kind of arragement construction of electric controlled turbocharger, including engine and the above structure are retouched
The electric controlled turbocharger stated, electric controlled turbocharger integral arrangement is in the side of engine, the resonant cavity and electronic execution
Device is arranged on the outside of engine.
The present invention has the advantages that compared with traditional booster technology
1. a booster has cavity resonator structure to be integrated in blower outlet, arragement construction can be made more compact, and effectively reduce
The pneumatic noise of compressor.
2. Electric Actuator is arranged on the outside of booster by booster, supercharger volute import segment length can be effectively shortened
Degree, makes that supercharger structure is more compact, weight is lighter；
3. the Electric Actuator structure of booster uses damping pad, can effectively inhibit caused by engine impulse pressure
Actuator taps abnormal sound.
4. the arrangement of resonant cavity and Electric Actuator on booster, keeps booster overall structure more compact, thus
Make that the surplus of its arrangement space is bigger, also has more advantage in terms of lightweight and cost control, exists to be more advantageous to booster
Arrangement on engine.
