Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
With the continuous development of scientific technology, the continuous improvement of people's living standard, automobile have become people it is daily go out
The essential vehicles of row.Automobile can be divided into manual transmission and automatic transmission according to the difference of gearshift mode.From
The vehicle of dynamic speed changer is simple, easy to use due to driving, and has become the main flow direction of speed changer development, increasingly by
The welcome of people.Automatic transmission include it is a set of prevent safety device-halting mechanism of vehicle sliding, halting mechanism can
Make automobile reliable and no time limit be parked on certain position even abrupt slope.
Halting mechanism is the safety device for preventing in automatic transmission vehicle from sliding, and therefore, how to improve halting mechanism
Security and reliability are the current problems for being badly in need of solving.
In halting mechanism in correlation technique, there are mechanical parking, three kinds of parking modes of motor parking and hydraulic pressure parking, wherein
Mechanical parking is low because of cost, and reliability is high and is widely used on speed changer, and common mechanical parking mainly includes ratchet assembly, changed
The compositions such as shelves rocking arm, parking arm and parking gear.The parking arm of this halting mechanism has the arm for being used for being caught in park tooth race
Tooth.
Due to vehicle, when keeping parking, arm tooth stress is larger and the stress time is long, therefore has following two risks, and one is
In parking, the arm tooth surface contact stress of parking arm is big, causes the tooth surface abrasion of arm tooth serious, two be parking arm be unfavorable for from
Deviate from parking gear, cause parking function to fail.
Therefore, the utility model proposes a kind of halting mechanism, the arm tooth and parking gear of the parking arm of the halting mechanism
The gear teeth between contact stress it is small, the two is not easy failure, and the arm tooth of parking arm can be easily from the wheel of parking gear
Depart between tooth.
Parking gear 110 and parking arm 120 can be included according to the halting mechanism 100 of the utility model embodiment.
Wherein, as depicted in figs. 1 and 2, first gear teeth 111 at multiple intervals are provided with the outer peripheral face of parking gear 110,
Park tooth race 101 is formed between two adjacent first gear teeth 111.
Second gear teeth 121 are provided with parking arm 120, when parking arm 120 is close to parking gear 110, second gear teeth 121
(that is, park tooth race 101) is fastened between two adjacent first gear teeth 111 to realize parking.
Wherein, second gear teeth 121 have the first relative flank of tooth 121a and the second flank of tooth 121b, the first flank of tooth 121a and the
At least one of two flank of tooth 121b is configured to arcwall face.That is, one in the first flank of tooth 121a and the second flank of tooth 121b
For arcwall face, or the first flank of tooth 121a and the second flank of tooth 121b are arcwall face.
Thus, the contact stress being provided between second gear teeth 121 of arcwall face and first gear teeth 111 diminishes, and vehicle exists
Also it ensure that halting mechanism 100 does not fail during long-time parking.In addition, improve after second gear teeth 121 can easily from
Depart between two adjacent first gear teeth 111 so that the releasing of vehicle parked state is more smooth, and Consumer's Experience has been obtained greatly
Width improves.
The work of the operation principle of the halting mechanism 100 of the utility model embodiment and the halting mechanism 100 of prior art
Principle is same or similar, repeats no more here.
According to the halting mechanism 100 of the utility model embodiment, by by two of second gear teeth 121 on parking arm 120
At least one of the individual flank of tooth is configured to arcwall face, reduces the contact stress between second gear teeth 121 and first gear teeth 111, carries
The high service life of halting mechanism 100, and second gear teeth 121 more easily control can depart from from park tooth race 101, release
Parked state is more smooth, improves the use feeling of human pilot.
According to one embodiment of the present utility model, the first flank of tooth 121a and the second flank of tooth 121b are configured to arcwall face.
Thus, no matter which kind of state vehicle is in, and second gear teeth 121 are arcwall face with the face that parking gear 110 is contacted, and then reduces
Contact stress between second gear teeth 121 and first gear teeth 111, the service life of halting mechanism 100 is further carried
It is high.
Further, the first flank of tooth 121a and the second flank of tooth 121b protrudes to direction away from each other.Thus, first flank of tooth
121a and the second flank of tooth 121b can be contacted more easily with parking gear 110, improve parking effect.
In some embodiments of the present utility model, first gear teeth 111 have relative the 3rd flank of tooth 111a and the 4th tooth
Face 111b.
As shown in Fig. 2 the 3rd flank of tooth 111a and the 4th flank of tooth 111b can be plane, further the 3rd flank of tooth 111a
It is parallel to each other with the 4th flank of tooth 111b.Thus, first gear teeth 111 are processed simply, convenient formation.
At least one in 3rd flank of tooth 111a and the 4th flank of tooth 111b is configured to arcwall face, that is to say, that the 3rd flank of tooth
One in 111a and the 4th flank of tooth 111b construction can be arcwall face, or the 3rd flank of tooth 111a and the 4th flank of tooth 111b whole
It is configured to arcwall face.
Thus, the contact stress between first gear teeth 111 and second gear teeth 121 is reduce further, the first round is reduced
Damage probability between the gear teeth 121 of tooth 111 and second, improves the service life of halting mechanism 100.
In some embodiments of the present utility model, parking arm 120 has first end and the second end, and parking arm 120 is around the
One end is rotated so that second gear teeth 121 are closer or far from parking gear 110, and second gear teeth 121 are arranged on first end and the
Between two ends.
That is, second gear teeth 121 are not located at second end farthest apart from first end, second gear teeth 121 and the
It is spaced a distance between one end, between second gear teeth 121 and the second end.
Specifically, the distance of second gear teeth 121 and first end is L1, and the distance at second gear teeth 121 and the second end is L2,
L1/L2 is met：1≤L1/L2≤3.
Thus, the difficulty of processing of parking arm 120 is reduced, the bonding strength between second gear teeth 121 and parking arm 120 is more
Height, reduces the probability of second gear teeth 121 fracture, improves the service life of halting mechanism 100.
Include the halting mechanism 100 of above-described embodiment according to the vehicle of the utility model embodiment.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
