Technical field
The present invention relates to a kind of technology of field of electric control, specifically a kind of electronic parking mechanical actuating mechanism.
Background technology
Electronic parking (E-park system) refers to, when automobile shift is suspended to P gear, complete by electronically controlled mode
Parking braking.According to the operation principle of electronic parking mechanism, electric drive unit and two portions of mechanical actuating mechanism can be classified as
Point, wherein electric drive unit includes motor, electric machine controller, reducing gear (as turbine and worm decelerator) and correlation and patches
Part, mechanical actuating mechanism mainly includes the associated components such as parking gear, ratchet, spring.Traditional manual halting mechanism has structure
The shortcomings of complexity, volume are larger is it is impossible to directly apply to new forms of energy power assembly system.Existing electronic parking mechanical actuating mechanism
Mostly cannot bear larger bear load, stability bad the shortcomings of, lead to electronic parking system not to be widely used.
Content of the invention
The present invention is directed to existing apparatus and leads to that volume is larger cannot to be applied to pure electric shift case due to structure design characteristic,
And noise larger while maintenance cost also of a relatively high the problems such as, a kind of electronic parking mechanical actuating mechanism is proposed so that staying
The distribution of mechanism of car load is more uniform, be greatly lowered case of transmission due to gravitation lead to impaired, improve whole system
Stability.
The present invention is achieved by the following technical solutions：
The present invention includes：With gear box casing be connected supporting plate be connected by cam axle with supporting plate cam,
Pass through screw with supporting plate and short pin rotates the ratchet being connected and rotates the parking gear being arranged on gear box casing, its
In：The both sides of ratchet are contacted with parking gear and cam respectively and are connected by torsion spring between ratchet and screw, cam with convex
Pass through spring between wheel shaft to be connected, camshaft is contacted with row's pin surely.
Technique effect
Compared with prior art, camshaft of the present invention passes through gear box casing, drives it to rotate thus complete by parking motor
Become parking and parking unlocking motion.Because camshaft one end is outside change speed gear box, therefore when parking electrical fault occurs, removable
Except parking motor and then by instrument rotation cam axle, manually complete parking and parking unblock.Which greatly enhances whole parking
The safety and reliability of system.

Specific embodiment
As depicted in figs. 1 and 2, described supporting plate 3 is provided with the short pin-and-hole 7 of two screw holes 1,2, first and first and has strong market potential
Hole 9, is respectively used to arrange two screws, a short pin and one and has strong market potential and supporting plate 3 is connected with gear box casing 14, ratchet
5 are socketed on and have strong market potential on 9 and rotate about, and cam 13 is socketed on camshaft 4 and is connected by spring 10, and electric drive unit passes through
Camshaft 4 drives mechanical actuating mechanism, as shown in Figure 2.
As illustrated in figures 3 a and 3b, one end of described supporting plate 3 is provided with a projective structure 16, when described ratchet 5
During rotation, this projective structure 16 can play spacing and guide effect, improves the stability of whole system.
Certain row's pin 15 set up on described gear box casing 14, corresponding as shown in figures 4 a and 4b, described camshaft 4
It is provided with the corresponding multiple slots 19 surely arranging pin 15, thus constituting the fixed pin-slot self-locking mechanism II that arranges to improve self-locking further
The accuracy of positioning.
As illustrated in fig. 4 c, described spring 10 adopts circular many coil springs, thus improving system strength further.
During normal parking, if ratchet 5 tooth top is just to parking gear 6 teeth groove, Motor drive camshaft 4 rotates, driving cam
Axle 4 is rotated by spring 10 driving cam 13, and cam 13 pressure turns ratchet 5 and enters parking gear 6；If ratchet 5 tooth top just to stay
Skiving wheel 6 tooth top, then contacted with parking gear 6 when ratchet 5 rotates an angle to, and now ratchet 5 and cam 13 cannot continue
Rotation, but camshaft 4 may proceed to rotate to final position and extension spring 10, when automobile continues on or retreats a small distance
Make ratchet 5 tooth top just to parking gear 6 teeth groove, then spring 10 can discharge the elastic potential energy of storage, driving cam 13 continues rotation
Turn so that ratchet 5 enters parking gear 6, complete parking.
During parking unblock, Motor drive camshaft 4 is inverted to final position compression spring 10, under spring force
Cam 13 starts to reversely rotate, and ratchet 5 completes to unlock under the opposition of torsion spring 8 and parking gear 6.
Compared with prior art, under normal operation, ratchet 5 can bear very big load to this device, these load
The correspondence position of gear box casing 14 will be directly delivered to, if gear box casing 14 insufficient strength, will result directly in housing 14
Raw moderate finite deformation even damages, and affects normal working performance.And in this device, payload segment can be transmitted by supporting plate 3
Other local on gear box casing 14, corresponding 2 short pins 7, thus greatly reduce housing 14 to destroy risk.
Additionally, being further provided with self-locking mechanism in this device, this self-locking mechanism includes cam-ratchet as shown in Figure 5 and connects
Tactile type face self-locking mechanism I, that is, cam 13 be respectively equipped with, in the side contacting, the type face being mutually matched with ratchet 5.Or adopt worm gear
Worm screw self-locking structure.Electronic parking mechanical actuating mechanism is jointly improved with fixed row pin-slot self-locking mechanism II by self-locking mechanism I
Reliability.This is very necessary for the electric drive unit of no auto-lock function.
As shown in fig. 6, the supporting plate 3 extended type structure described in the present embodiment, that is, its length is on Fig. 3 a basis enterprising
Step lengthens, and sets up location hole in the end of elongated portion, i.e. the second short pin-and-hole 17.
As shown in fig. 7, above-mentioned supporting plate 3 is based on this second short pin-and-hole 17 arranges the second short pin 18, for connecting bracket plate 3
With gear box casing 14, improve the locating effect of supporting plate 3 by the spacing of the first short pin 7 and the second short pin 18, you can to have
Effect reduces the position degree required precision of corresponding aperture on supporting plate 3, reduces the processing cost of supporting plate 3.
Above-mentioned be embodied as can by those skilled in the art on the premise of without departing substantially from the principle of the invention and objective with difference
Mode local directed complete set is carried out to it, protection scope of the present invention is defined by claims and is not embodied as institute by above-mentioned
Limit, each implementation in the range of it is all by the constraint of the present invention.
