Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
It refer to Fig. 1-Fig. 4, structure when Fig. 1 is the first state of cam-and- provided in an embodiment of the present invention
Schematic diagram；Structural representation when Fig. 2 is second of state of cam-and- provided in an embodiment of the present invention；Fig. 3 is this
Structural representation during the third state for the cam-and- that inventive embodiments are provided；Fig. 4 provides for the embodiment of the present invention
Cam-and- structural representation.
Cam-and- provided in an embodiment of the present invention, including rocking arm 1, cam 2 and gear 3, rocking arm 1 include arm body and
Ring body, arm body, which is inclined on the side of ring body, rocking arm 1, is provided with the first rotary middle point A, the first rotary middle point A
Between ring body and arm body, cam 2 is built in ring body and itself had on the second rotary middle point D, the inwall of ring body and sets
There is lug boss, the top of rocking arm 1 is provided with hock, and hock is used cooperatively with gear 3, gear 3 has the 3rd rotary middle point B,
The tooth form central point C of hock is arranged on using the first rotary middle point A as the center of circle, in being rotated with the first rotary middle point A to the 3rd
Heart point B is on the circle of radius, during parking, as shown in figure 1, when cam 2 turns clockwise and blocked by lug boss, cam
2, which continue to turn clockwise, promotes rocking arm 1 to be rotated counterclockwise around the first rotary middle point A, and hock is engaged with gear 3, such as Fig. 2 institutes
Show, now gear 3 can not be rotated, in parking disconnecting process, as shown in figure 3, when the rotate counterclockwise of cam 2 is by the inwall of ring body
When blocking, cam 2 continues rotate counterclockwise and promotes rocking arm 1 to be turned clockwise around the first rotary middle point A, hock and gear 3
Depart from.
Cam-and- provided in an embodiment of the present invention compared with prior art, reduces the power out of supply of parking gear, leads to
Cross and the tooth form central point C of hock is arranged on using the first rotary middle point A as the center of circle, revolved with the first rotary middle point A to the 3rd
Turn on the circle that central point B is radius, so that the interference between reducing the gear teeth of hock and gear 3, when gear 3 has movement tendency
It is more beneficial for hock and departs from gear 3.
Moreover, based on more than design, cam-and- provided in an embodiment of the present invention compared with prior art, Neng Goujin
The outside circle of the tooth form for reducing rocking arm 1 and gear 3 of one step；Can so make rocking arm 1 and gear 3 arrangement distance reduce so as to
The swingable smaller angle of rocking arm 1 is just disengaged with gear 3 so that the size of cam 2 reduces than before, and whole mechanism is ensureing
Space-consuming has also reduced than before while intensity.Simultaneously because the height reduction of the tooth form of gear 3 makes in actual use
The tooth contact area of the hock and gear 3 that obtain rocking arm 1 reduces, so that the frictional force between reducing them；This kind of form is set
Count A, B, C 3 positions also can more according to the reasonable reconnaissance of space reasonable Arrangement, so as to make parking than lever ratio have it is larger can
Adjusting range, adds applicability of this kind of mechanism in different type of machines.
When cam 2, which turns clockwise, to be blocked by lug boss, now moved to for rocking arm 1 at the range of cam 2.When
When the rotate counterclockwise of cam 2 is blocked by the inwall of ring body, now moved to for rocking arm 1 at the range of cam 2.
Wherein, lug boss is arc convex close to the side that cam 2 is used to block cam 2.Lug boss away from cam 2 one
Side is arc convex.
The embodiment of the present invention also provides a kind of vehicle, including parking rocking arm, and parking rocking arm is that above-mentioned any one such as is implemented
Cam-and- described in example.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
