Description
Technical field
The utility model relates to automotive fields, more particularly to for installing, plug-in hybrid car is dedicated to be started one kind
The damping device of machine.
Background technique
Plug-in hybrid-power automobile (Plug-in hybrid electric vehicle, abbreviation PHEV) is novel
Mixed power electric car.It is different from hybrid power of the conventional gasoline power in conjunction with electric drive, plug-in hybrid driving
Principle, driving unit are identical as electric vehicle, unique the difference is that being equipped with an engine on vehicle.
The difference of plug-in hybrid-power automobile and ordinary hybrid automobile: the battery capacity of ordinary hybrid vehicle is very
It is small, only rise/stop, plus/minus speed when supply/recover energy, be unable to external charging, pure power mode relatively long distance row cannot be used
It sails；The battery of plug-in hybrid electric vehicle compares larger, can be travelled with pure power mode, battery capacity with external charging
Again with hybrid mode (based on internal combustion engine) traveling after exhausting, and charge in due course to battery.
With the rapid development of the automotive industry, Automobile Design develops towards lightness and economization, high-power engine and
The use of lightweight automotive material, the vibration amplitude for making engine be transferred to vehicle body increase.It is generated in engine working process
Out-of-balance force and torque and the unevenness on road surface are the main driving sources of automobile vibration, and engine is as the most important vibration source of automobile
One of, if the vibration generated cannot control well, other parts that Metal Sheets for Body-manufacturing can be caused to be connected with vehicle frame are produced
Raw abnormal vibrations and noise, while the control stability and ride comfort of automobile are influenced, the components of automobile are even damaged when serious,
Shorten the service life of automobile.In the engine all working range of speeds, the vibration that engine generates must be by suspension
System is isolated, and reduces the vibration for passing to automobile chassis and vehicle body as far as possible, while suspension system also needs to be isolated by road not
The vibration of wheel, suspension system caused by flat prevents this vibration from transmitting to engine, engine luggine is avoided to aggravate, with full
Stationarity and comfort when sufficient vehicle is run, and guarantee the stability of engine when idling and shutdown, Engine Mounting System
Effect see some from this.But orthodox car engine mounting product existing defects in the design of damper at present, and
And tradition suspension shock absorber rubber structure is too long, poor rigidity, causes engine operation amplitude larger, resonance of the car is caused to be difficult to control
System, the noise generated in the process of moving is larger, vibration is larger, and vehicle comfort reduces.
