Detailed description of the invention
In order to more clearly describe technology contents of the present utility model, carry out into one below in conjunction with specific embodiment
The description of step.
This utility model provides a kind of P shelves halting mechanism, and this mechanism includes parking motor, transmission component and locking group
Part, described lock assembly includes locking rod 9 and brake disc 2, and described parking motor passes through described transmission component and locking
Bar 9 is connected, and described locking rod 9 can connect with brake disc 2 or separate under the driving of parking motor.
In one preferably embodiment, described locking rod 9 is provided with rectangle brake tooth, described brake disc 2
On be provided with the rectangular channel corresponding with described rectangle brake tooth.
In one preferably embodiment, described transmission component includes worm gear 3, worm screw 1 and tappet 7, and described stays
Vehicle motor is connected with worm gear 3 by worm screw 1, and the bearing pin 6 on described worm gear 3 is by described tappet 7 and described locking
Bar 9 is connected.
In one preferably embodiment, described lock assembly also includes that torsion spring 10, described torsion spring 10 are arranged at
On described locking rod 9.
In one preferably embodiment, described brake disc 2 is connected with the variator II axle 13 of vehicle.
This utility model further relates to a kind of control system for described P shelves halting mechanism, and this system includes that first continues
Electrical equipment, the second relay and VCU, the first end of the first described relay is connected to parking motor, the first described relay
The second end be connected to VCU, the three-terminal link of the first described relay to driving power supply, the of the second described relay
One end is connected to parking motor, and the second end of the second described relay is connected to VCU, the 3rd end of the second described relay
It is connected to drive power supply.
