Refering to Fig. 5, described park pawl assembly includes park pawl 7, park pawl pin 8 and park pawl roller 9；
The described interference of park pawl bearing pin 8 is arranged in park pawl 7, and park pawl roller 9 can be around park pawl bearing pin 8 freely
Roll.The both ends of park pawl axle 6 are arranged in the hole of the forward and backward shell 23,24 of speed changer, and park pawl assembly can be around parking spine
Pawl axle 6 rotates.
Refering to Fig. 4, described parking protecting against shock Cam set assembly includes parking axle 1, fanning strip 2, torsion spring 3, the and of parking cam 4
Parking pivot pin axle 5；Parking axle 1 and the laser welding of fanning strip 2, parking axle 1 can rotate in transmission case body opening.Plate spring assembly 15
First and second bolt 16,17 in footpath is led by two bands and a common clamping screw 18 is fixed on fore shell 23, leaf spring
Roller on assembly 15 coordinates the conversion for realizing PRNDS gears with the wave-shaped groove of fanning strip 2.Plate spring assembly 15 has deformation displacement
The characteristics of small, elastic force is greatly and steady, and the life-span is high and easy for installation.PRNDS sensors 12 are sleeved on the flat place of the milling of parking axle 1, can
Rotated with parking axle 1, exporting electric signal by the different angle positions of PRNDS gears is sent to speed changer TCU.Gear arm 11 is pacified
On parking axle 1, locked with locking nut 10.
Refering to Fig. 3, described parking oil sealing 13 is fitted in fore shell 14, and parking axle 1 is rotated in it, avoids oil leak and outer
Portion's impurity enters gearbox.
Refering to Fig. 1, Fig. 2, when P, which is kept off, to be combined, handle bracing wire pulls gear arm 11, drives parking axle 1 and is welded thereon
Fanning strip 2 rotate, fanning strip 2 drives parking cam 4 by its torsion spring 3, and now, torsion spring 3 plays a part of power transmission.Parking is convex
Wheel 4 promotes park pawl 7 to move downward and realizes parking function after rotating.Meanwhile parking cam bearing pin 5 is also with parking axle 1 one
Rise and rotate, play spacing effect.If park pawl 7 can not be depressed and fall into the teeth groove of parking gear 20 by parking cam 4
In, parking cam 4 will bear against on park pawl roller 9.At this moment, parking cam 4 is not deformed, played in the position of combination, torsion spring 3
The effect of energy storage.After vehicle car slipping, parking cam 4, which rotates, to be pressed into park pawl 7 in the teeth groove of parking gear 20, realizes P
Gear combines.
Refering to Fig. 1, Fig. 2, when P, which is kept off, to be separated, handle bracing wire promotes gear arm 11, drives parking axle 1 and is welded thereon
Fanning strip 2 rotate backward, after rotating parking cam 4, park pawl 7 pops up, and park pawl 7 is from parking gear 20
Deviate from teeth groove, parking realizes that P keeps off separation function.Now, the arc surface of park pawl roller 9 and parking cam 4 is in contact, and stays
Car ratchet assembly is delivered on parking axle 1, final work to the impulsive force of parking Cam set assembly by the arc surface of parking cam 4
With on fore shell 23 and rear shell 24.
Refering to Fig. 7, this parking cam 4 with arc structure can bear larger impulsive force, and can pass impulsive force
It is delivered on case of transmission, can prevents the halting mechanism caused by impulsive force from failing.Park pawl bearing pin 8 is convex in parking all the time
Moved in stopper slot 4-1 on wheel 4, stopper slot 4-1 plays vehicle prevents it from causing to stay due to vehicle vibration in the process of moving
Car ratchet 7 is fallen into the teeth groove of parking gear 20 by mistake, and the direction of rotation of the parking cam 4 such as direction of arrow in Fig. 7 is consistent when plucking gear.
Gear power is plucked on the road of slope to reduce halting mechanism, the application realizes in terms of following four.
1. refer to Fig. 3, first and second steel is separately installed with fore shell 23 and rear shell 24 by composite bush 14,19, steel is answered
Closing bush inside has PTFE coatings, can effectively reduce friction, avoid parking axle 1 and housing bore from directly contacting, avoid stressing conditions
It is lower glued phenomenon occur.
2. referring to Fig. 3, parking camshaft assembly side is positioned using the end face of fanning strip 2 and the end face of fore shell 23, and opposite side is adopted
Positioned with the shaft end of parking axle 1 and the parking axis hole end face of rear shell 24, gap is left between the end face of cam 4 and the end face of rear shell 24.Adopt
Friction can be effectively reduced with the positioning of the shaft end of parking axle 1, avoids the side of cam 4 from being scraped with the end face of rear shell 24.
3. referring to Fig. 8, the flank of tooth of parking gear 20 is arc structure, when 20 joggleword of park pawl 7 and parking gear,
The stress state of flank of tooth when can improve the parking of slope road, avoid because the stress raisers flank of tooth destroys, therefore when gear is plucked on slope road,
Circular-arc tooth surface structure is easy to park pawl 7 to be ejected from parking gear 20.
4. referring to Fig. 4, parking cam 4 is eccentric structure, i.e. the center of circle of radius " R " and the decentraction of the cam hole center of circle.Slope road
When plucking gear, eccentric structure can produce power-assisted square, and cam rotation direction is consistent when direction is with plucking gear, thus can effectively reduce and pluck gear
Power.
