Description
Technical field
The utility model relates to a kind of automobile-used P grades of lockable mechanism of miniature electric, belong to power driving system for electric vehicle
In parking device technical field.
Background technology
At present, the parking device of power driving system for electric vehicle is a kind of P shelves lockable mechanisms of use threaded screw rod mechanism, should
Structure is that motor power is transferred into ejector pin by threaded screw rod mechanism, and ejector pin promotes ratchet to enter parking gear, realizes P grades of locks
Only function；Retracted again by motor after threaded screw rod mechanism, revocation power, ratchet is retracted by return spring.Realize unlocking function.Should
The drawbacks of mechanism is maximum is the transmission power that is mostly rigidly connected, and working life is shorter, motor longevity of service, and rear spiral shell is used for multiple times
Line is easily damaged, and feed speed is limited by pitch.Application in mini electric vehicle is not also very extensively, to belong to process on probation
In, because mini electric vehicle is not used also as new energy vehicle by large batch of.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art has that there is provided a kind of long working life, motor work
It is short to make the time, is quick on the draw, safe and reliable, can quickly realize the miniature electric of electric car parking function during enforcement
Automobile-used P grades of lockable mechanism.
The utility model is completed by following technical solution, a kind of automobile-used P grades of lockable mechanism of miniature electric, and it leads
To be made up of motor and lockable mechanism two parts, described motor is with turbine and worm mechanism and installed in subtractive speed
On device；Lockable mechanism is located in the casing of difference speed reducer assembly, including motor input axle assembly, locking pushing block, working spring, stays
Car ratchet, park pawl rotating shaft, return spring, parking gear, the motor input axle assembly are defeated by motor input shaft and motor
Enter axle support base hot jacket to be integrally fixed, the motor input shaft empty set is on difference speed reducer housing；Locking pushing block empty set is in electricity
On machine input shaft support base, locking pushing block is connected together with motor input shaft support base by working spring, a flexibility is realized
Pushing mechanism；Park pawl rotating shaft be arranged on difference speed reducer front and rear casing on, and can flexible rotating, park pawl empty set in
In car ratchet rotating shaft, held by the return spring being fixed on housing；Locking pushing block has two positions of locking and unblock respectively；Difference
Stopping means is carried on the housing box body of decelerator；Parking gear is fixed on the input shaft of difference speed reducer by spline.
As preferred：Described motor receives PCU instructions, rotates clockwise and transfers a torque in lockable mechanism
Motor inputs axle assembly, and motor input axle assembly drives locking pushing block, park pawl is caught in parking gear by locking pushing block,
And parking gear is fixed on the input shaft of difference speed reducer assembly, input shaft is locked immediately, so as to quickly realize P grades of locking work(
Energy；When motor reversion, locking pushing block is driven by motor input shaft and turned round, after electric car starts, and return spring immediately will
Park pawl is exited from parking gear, realizes unlocking function.
P shelves lockable mechanism of the P grades of lockable mechanism device described in the utility model relative to existing use threaded screw rod mechanism
Will be more fast and safely reliable, with long working life, the motor working time is short, is quick on the draw, safe and reliable, can be quick
Realize mini electric vehicle the features such as parking function during enforcement.
Brief description of the drawings
