As shown in Figure 2.
In some embodiments of the invention, unlock detection plate 66 in place, the second nut 63 are provided on the first nut 62
On be provided with locking detection plate 67 in place, be fixed on shell 1 with unlock in place detection plate 66 cooperate unlock Hall connects in place
Nearly switch 68 and with the locking of the locking cooperation of detection plate 67 in place proximity Hall switch 69 in place.Unlock in place detection plate 66 with
Proximity Hall switch 68 cooperates in place for unlock, whether in place to can detecte unlock.Detection plate 67 and locking be in place suddenly in place for locking
You cooperate close to switch 69, whether in place to can detecte locking.
Below with reference to the working principle of Fig. 1, Fig. 4-Figure 11 detailed description halting mechanism 100:
(1) non-on-position
For non-on-position as shown in Figure 1, two parking rack gears 4 are far from parking gear 2, the reconciliation of the first nut 62 is locked into position suddenly
You are standard value close to the distance of switch 68, and the magnetic flux for unlocking proximity Hall switch 68 in place at this time is also standard value, program
It can detecte unlock in place.Screw rod 61 has self-locking function, and the first nut 62 and the second nut 63 will not automatic movings.It is anti-
Accident only occurs, the displacement of the first nut 62 and the second nut 63 can be monitored by Programmable detection magnetic flux change, it can also be with
Mechanical positioner is installed additional between swing arm sprue 33 and shell 1, to improve the reliability of halting mechanism 100.In preceding primary solution
After the completion of lock, parking rack gear 4 has automatically returned to the middle position of sliding slot 31 under the action of the first spring 51, second spring 52,
Parking rack gear 4 is far from parking gear 2, and parking gear 2 is although operate, but not interfere with parking rack gear 4.It is at this time
Travel vehicle in bumpy road, parking rack gear 4 under the effect of gravity can pressuring spring component generate vibration, but spring assembly is rigid
Spend larger, therefore the vibration of parking rack gear 4 cannot be arrived by visual observations.
(2) first stage of parking braking --- hollow travel stage
The first stage (see Fig. 4) of parking braking is the addendum line and park tooth that parking rack gear 4 is moved to by unlocked state
The outside circle of wheel 2 is tangent.After being connected to parking instruction, driving motor 64 drives screw rod 61 to rotate, the first nut 62 and the second spiral shell
Mother 63 moves to the direction far from boss 613 simultaneously.In the process, unlock in place detection plate 66 simultaneously far from unlock in place suddenly
, close to switch 68, the detectable magnetic flux for unlocking proximity Hall switch 68 in place of program becomes smaller rapidly, but is still greater than locking for you
The magnetic flux of proximity Hall switch 69 in place.First nut 62, the second nut 63 ear pin 65 drive two parking swing arms 3 respectively
It is rotated around respective parking arm shaft 7, the parking rack gear 4 in parking swing arm 3 moves closer to parking gear 2, when halting mechanism 100
After a period of work, 4 addendum line of parking rack gear and 2 outside circle of parking gear are tangent.So far, the parking rack gear gear teeth 41 also not with
The parking gear gear teeth 21 are in contact, and are the hollow travel stages of halting mechanism 100.During this period of time, the drive system of vehicle
It stops working, vehicle gradually slows down, but not can determine that whether vehicle immobilization.Compared with traditional cone pulley parking system, this hair
The idle stroke range of bright halting mechanism 100 is more casual, and design space is larger.
(3) second stage of parking braking-addendum circle arc contact slide stage
When 100 continuous work of halting mechanism to 4 addendum line of parking rack gear and 2 outside circle of parking gear it is tangent after, immediately into
Enter to second stage, i.e. addendum circle arc contact, pushing and sliding rather than engage, as shown in Figure 5.Due to by the tooth of parking rack gear 4
The tooth top of top and parking gear 2 is made to small arc-shaped, this circular arc is smoothly connected with the left and right flank of tooth, and without singular point, (it is designed
It is proprietary technology with technique), when the peak contact of the tooth top of the parking gear 2 of movement and static parking rack gear 4 (see Fig. 5
Shown in the upper right corner), the tooth top of parking gear 2 forces in the tooth top of parking rack gear 4 at once, makes parking rack gear 4 along itself nodel line
Movement, however the first spring 51 or second spring 52 can prevent parking rack gear 4 along the chute 31 movement.When beginning, due to vehicle
The inertia of movement is larger, and the elastic force of spring assembly is insufficient to allow parking rack gear 4 to stop, so parking rack gear 4 can still move.Due to
Parking rack gear 4 is only contacted in tip portion with parking gear 2, and parking rack gear 4, which is parked after gear 2 pushes sliding a bit of, just to be taken off
It is sprung back from contact.
By taking right side parking rack gear 4 is first contacted, is contacted after left side parking rack gear 4 with parking gear 2 with parking gear 2 as an example,
When second stage starts, the tooth top of parking rack gear 4 peak contact with parking gear 2 not yet on the left of Fig. 5, with braking
The progress of journey, after parking gear 2 rotates by a certain angle again, the tooth top of left side parking rack gear 4 just can be with the tooth of parking gear 2
Top contact when right side parking rack gear 4 is also underway, and takes turns to the tooth top and parking gear 2 and park tooth of left side parking rack gear 4
The peak contact of wheel 2, snubber contact impacts in turn for they.At present due to only entering at tooth top or exiting engagement, and entrance or
Exit that comparison is frequent, single parking rack gear 4 has reciprocating motion (springing back because the registration of engagement is less than 1), is similar to chain
Loosen the jump tooth with sprocket wheel.And two parking rack gears 4 will be such that the stroke of rebound reduces, and since parking swing arm 3 is continuously swung, stay
Skiving item 4 is also slided radially towards the center of parking gear 2, so this process will not be very long.In this stage, solution is locked into
Position detection plate 66 constantly far from unlock proximity Hall switch 68 in place, and locking in place detection plate 67 constantly close to locking in place suddenly
The close switch 69 of that.Detect and compare the magnetic flux of unlock proximity Hall switch 68 and locking proximity Hall switch 69 in place in place
It is found that the magnetic flux ratio of the unlock magnetic flux of proximity Hall switch 68 and locking proximity Hall switch 69 in place in place will be by big
It is transitioned into 1 equal to 1, then is transitioned into less than 1.
It should be pointed out that when unlock in place detection plate 66 away from unlock in place proximity Hall switch 68 distance be greater than locking
In place detection plate 67 away from locking in place proximity Hall switch 69 apart from when, proximity Hall switch 68 and locking be in place in place for unlock
The magnetic flux ratio of proximity Hall switch 69 is greater than 1.
When unlock in place detection plate 66 away from unlock in place the distance of proximity Hall switch 68 and locking in place detection plate 67 away from
Locking when being equidistant of proximity Hall switch 69 in place, Hall is approached and is opened in place for proximity Hall switch 68 and locking in place for unlock
The magnetic flux ratio for closing 69 is equal to 1.
When detection plate 66 away from the distance of unlock proximity Hall switch 68 is in place less than locking detection plate 67 in place in place for unlock
Away from locking in place proximity Hall switch 69 apart from when, unlock proximity Hall switch 68 and locking proximity Hall switch in place in place
69 magnetic flux ratio is less than 1.
(4) phase III-parking gear gear teeth 21 of parking braking start to engage and radially slide with the parking rack gear gear teeth 41
The dynamic stage
The beginning flag of phase III, which is the parking rack gear gear teeth 41, all to be entered with the parking gear gear teeth 21 and initial engages shape
State, the normal of 41 teeth outline of the parking rack gear gear teeth and the basic circle of parking gear 2 start tangent (see shown in Fig. 6 and Fig. 7) at this time, stay
The meshing point of skiving wheel 2 and parking rack gear 4 is on this tangent line.Only from engagement, parking gear 2 pushes parking rack gear 4
Linear movement.Although the parking gear gear teeth 21 and the parking rack gear gear teeth 41 are " real " engagements, due to just initially entering
The operating center distance of engagement, parking gear 2 and parking rack gear 4 is much larger than reference center distance, therefore the starting point engaged extremely terminates
The distance of point is much smaller than 1 much smaller than base pitch namely registration, can not achieve continuous engagement, the i.e. linear movement of parking rack gear 4
Cannot be continuous, slippage phenomenon still remains.At this time since parking swing arm 3 constantly moves, parking swing arm 3 is to 2 center of parking gear
Swing so that parking rack gear 4 is directly toward the sliding of parking gear 2, the engagement of parking gear 2 and parking rack gear 4 is more and more as a result,
Deeply, the center of parking gear 2 and parking rack gear 4 away from constantly to standard value it is close, when center is less than 0.5439m (by scheming away from difference
Show that parameter calculates) when, the reciprocating motion (springing back) of parking rack gear 4 will disappear.In this stage, detection plate 66 in place are unlocked
It is increasingly remoter that dissociation is locked into a proximity Hall switch 68, and locking in place from locking, get over detection plate 67 in place by proximity Hall switch 69
Come it is closer, by Fig. 6 it can be seen that.The value at this point, magnetic flux of locking proximity Hall switch 69 in place should be near the mark.
(5) nodel line of the reference circle and parking rack gear 4 of fourth stage-parking gear 2 of parking braking is tangent
The phase III engaged and radially slided carries out to a certain extent, just coming another significant key point, i.e. parking
The theory state that gear 2 is engaged with parking rack gear 4.If parking gear 2 drives in the sometime vehicle immobilization of phase III
The movement that parking rack gear 4 moves linearly stops, and the swing in parking swing arm 3 towards 2 axle center of parking gear does not stop, until staying
The nodel line of skiving item 4 and the reference circle of parking gear 2 are tangent, as shown in Figure 8.Since the theory state of gear engagement is zero-clearance
, therefore when the reference circle of the nodel line of parking rack gear 4 and parking gear 2 is tangent, their between cog is zero-clearance.This moment, it stays
Vehicle swing arm 3 cannot move again.That is, the nodel line of zero-clearance and reference circle it is tangent be parking swing arm 3 stop mark.If vehicle
Do not stop, although parking swing arm 3 have been moved to the nodel line and parking gear 2 that make parking rack gear 4 reference circle it is tangent and from
Body stop, parking gear 2 be still to rotation until vehicle stops or parking gear 2 to push parking rack gear 4 move linearly, until
Second spring 52 is compressed to most short by parking rack gear 4, could stop vehicle.The stopping of vehicle and initial velocity, transmission internal resistance, road
Face situation, wind direction etc. are related, no matter but whether stop, parking swing arm 3 will move to always the nodel line of parking rack gear 4 and stay
Just stop when the reference circle of skiving wheel 2 is tangent.It thus can be in calibration with the nodel line of parking rack gear 4 and parking gear 2
Subject to reference circle is tangent, by locking at this time, detection plate 67 is set as marking at a distance from locking in place proximity Hall switch 69 in place
Quasi- value, and magnetic flux at this time is also standard value.
(6) the 5th stage-parking gear 2 of parking braking engages real zero-clearance with parking rack gear 4
Since the manufacture of any machine components all has error, in order to which halting mechanism 100 of the invention can be by reality
Border application, discusses parking rack gear 4 and the real zero-clearance state of parking gear 2 herein.Parking rack gear 4 be rack gear, space width with
Transverse tooth thickness phase etc. is the nodel line position of parking rack gear 4.Size between the nodel line of parking rack gear 4, the gear teeth and tooth socket has certain system
Make error.Parking gear 2 is gear, and foozle value is related with precision, cost.In the actual production process, parking gear 2
Foozle according to 8 class precisions, unilateral tooth thickness error 0.05mm causes 2 times of center away from displacement (30 ° of profile angles).
The foozle of parking rack gear 4 and parking gear 2 to when enter parking phase III and fourth stage have an impact, it is most substantive
Influence be finally embodied in locking in place detection plate 67 at a distance from locking in place proximity Hall switch 69 and the magnetic that detects
Flux.Since 8 influences of the class precision horizontal centring heart away from displacement are little, only driving motor 64 need to be allowed to run to parking in parking
Rack gear 4 and parking gear 2 are very close to each other.Two states are subject in assembly and calibration, specifically, parked state
When, parking rack gear 4 and parking gear 2 are (see Fig. 9) very close to each other, locking detection plate 67 and locking proximity Hall switch in place in place
69 distance is standard value, and magnetic flux is also standard value；When unlocked state, parking rack gear 4 and 2 gap of parking gear are maximum,
Detection plate 66 is standard value at a distance from unlock in place proximity Hall switch 68 in place for unlock, and magnetic flux is also standard value.
(7) it unlocks
It should first be unlocked before vehicle launch.After being connected to unlock instruction, driving motor 64 and oppositely oriented when parking, parking
The direction of motion of swing arm 3 is as shown by the arrows in Figure 10.After the disengaging parking gear 2 of parking rack gear 4 is remote enough, parking rack gear 4 exists
In having been returned automatically under the action of spring assembly.Driving motor 64 finally makes two parking rack gears 4 far from parking gear 2, works as unlock
When detection plate 66 is standard value at a distance from unlock in place proximity Hall switch 68 in place (magnetic flux is also standard value at this time), journey
Sequence can detecte unlock in place.State after the completion of unlock is shown in Figure 11.
(8) slope road parking
After driver stops vehicle on the slope, the trend of the road vehicle You Yanpo downslide.Ratchet is used for traditional
The vehicle of spine bar cone pulley structure parking on slope road when parking, prevents vehicle from being finally applied on cone pulley along the power that slope road glides.Make
After completing parking on slope road with the vehicle of halting mechanism 100 of the invention, also vehicle is allowed to glide along slope road, the range to glide
Pass through the control when designing spring.The maximum value of downslide is embodied in the rotation angle of parking gear 2.The power of downslide is stayed by one
Skiving item 4 is finally applied in parking swing arm 3, is ultimately applied on shell 1 by another parking rack gear 4.
It should be pointed out that parking gear 2 and parking rack gear 4 engage and parking swing arm 3 towards parking gear 2
Swing can all push 31 linear motion along the chute of parking rack gear 4, and the linear motion of parking rack gear 4 all can compression spring assembly.
