It is domatic that the side of face B dorsad face of cylinder A is formed with chamfering；Spring is formed with the domatic fan-shaped lateral margin of the chamfering
Boss.
Further, the articulated section is circle.
Further, some holes for mitigating weight or groove are disposed with the cam disc.
Further, the articulated section is integrally formed with the cam part, generally tabular.
The beneficial effects of the utility model are：The present invention provides a kind of cam for vehicle parking system actuator
Disk, the axis hole of cam disc articulated section are rotatably arranged in actuator drive shaft and around drive shaft turns, cam part side
Spring boss on fan-shaped lateral margin is used to install spring, and the spring other end is connected with the actuator being rotated by drive shaft, this
Sample, actuator Jing springs can driving cam portion side fan-shaped lateral margin, and the actuator can also driving cam portion opposite side fan
Shape lateral margin, makes cam disc swing back and forth.By face of cylinder A, climbing face, face of cylinder B, the domatic cam surface for constituting of chamfering and parking system
The swing arm of the ratchet of system or release boss directly contact.So, cam disc swings back and forth and ratchet can be driven to realize parking and unblock.
As cam disc is plate armature, simple structure, dependable performance can be greatly reduced the cost of parking system.

Specific embodiment
In order to be more clearly understood that technology contents of the present utility model, describe in detail especially exemplified by following examples, its mesh
Be only that and be best understood from content of the present utility model and unrestricted protection domain of the present utility model.
As depicted in figs. 1 and 2, a kind of cam disc for vehicle parking system actuator, including articulated section 1 and sector
Cam part 2, is formed with the axis hole 11 in drive shaft for turning set, in the sector of the cam part in the middle part of the articulated section
Edge is connected with the articulated section, and face of cylinder A21 and face of cylinder B22 is sequentially formed with the fan-shaped outer rim of the cam part, described
The radial height of face of cylinder A is connected between the face of cylinder A and the face of cylinder B less than the radial height of the face of cylinder B
Climbing face 23, the side of the face of cylinder B dorsad face of cylinder A are formed with chamfering domatic 24；It is domatic near the chamfering
Spring boss 25 is formed with fan-shaped lateral margin.
Preferably, the articulated section is circle.But not limited to this, other ellipse, arc, sectors etc. can be according to realities
Border needs to arrange.
Preferably, some holes for mitigating weight or groove 26 are disposed with the cam disc.Preferably, using circular logical
Hole, it is while mitigating the weight of cam disc, convenient to carry out.
Preferably, the articulated section is integrally formed with the cam part, generally tabular.Plate armature, structure letter
Single, dependable performance can be greatly reduced the cost of parking system.
As shown in figure 3, the application schematic diagram of the cam disc of parking system actuator of the present invention, the axle of cam disc articulated section
Hole is rotatably arranged in actuator drive shaft 3 and the spring in drive shaft turns, the fan-shaped lateral margin of cam part side is convex
Platform is used to install spring 4, and the spring other end is connected with the actuator 5 being rotated by drive shaft, and so, actuator Jing springs can
The fan-shaped lateral margin of driving cam portion side, and the actuator can also driving cam portion opposite side fan-shaped lateral margin, make cam disc
Backswing is moved.By the swing arm 61 of the ratchet 6 of face of cylinder A, climbing face, face of cylinder B, the domatic cam surface for constituting of chamfering and parking system
Or 62 directly contact of release boss.So, cam disc swings back and forth and ratchet can be driven to realize parking and unblock.
When vehicle parking, actuator is turned clockwise by Spring driving cam disc, due to face of cylinder A and face of cylinder B
Radial height is different, therefore, during face of cylinder A Jing climbings face turns clockwise to face of cylinder B, the cam surface of cam disc is promoted
The swing arm of ratchet so that ratchet is rotated counterclockwise, ratchet park pawl snap in the teeth groove of ratchet 7, so as to realize parking.
When ratchet reaches complete parking position, the face of cylinder B in the cam surface of cam disc is contacted with the swing arm of ratchet, by
Power between the swing arm of ratchet and face of cylinder B is cam disc radial direction, it is impossible to which driving cam disk is rotated, so as to limit spine
Pawl is rotated clockwise, and realizes the locking of ratchet.
When vehicle is unlocked, actuator direct drive cam disc is rotated counterclockwise, and the chamfering in cam disc cam surface is domatic
24 and detent contact, so as to ratchet is pushed open from parking position, ratchet is rotated clockwise under cam dish driving, by parking position
Rotate to unlocked position, after the teeth groove of ratchet and ratchet is disengaged, cam disc is rotated further under the driving of actuator, directly
Face of cylinder B into cam disc cam surface covers the teeth groove of ratchet, prevents ratchet from being entered by external force effect under non-parked state
In the teeth groove of ratchet, meanwhile, the face of cylinder A in the cam surface of cam disc is contacted with pawl swinging arm, prevents ratchet from rotating clockwise
Stroke it is excessive, beyond unlocked position.
As this utility model cam disc is plate armature, can using Sheet Metal Forming Technology processing in the case of production in enormous quantities
So that production cost is greatly reduced and simple and reliable for structure, while parking system cost is reduced, raising parking system can
By property.
Above example is referring to the drawings, preferred embodiment of the present utility model to be described in detail.The skill of this area
Art personnel by modification or change on various forms are carried out to above-described embodiment, but without departing substantially from substantive feelings of the present utility model
Under condition, all fall within protection domain of the present utility model.
