It further, can be with the building block of the formation transmission mechanism of integral type in supporting and mounting bracket.For example, first passes
The idle pulley support transmission shaft of dynamic grade, the axis pin of fixed driving device, planetary gear mechanism internal gear etc. can be integrally-formed
In in the supporting and mounting bracket.By this integrated fixed form, the installation of the sub-unit is not only simplified, and extends this point
The service life of assembly.Moreover, installing fixed form by this integrated form, such as the internal gear of planetary gear mechanism is integrated
It is fixed in supporting and mounting bracket, transmission mechanism can be effectively prevent to occur as the time increases in bearing top load transmission process
Mechanical connection generate relaxation risk.
The structure space of the sub-unit can be made to be optimized by carrying out structure design appropriate to supporting and mounting bracket, with
Space hold is reduced, the real vehicle arrangement of brake is conducive to.For example, it is preferable to supporting and mounting bracket 160 have stepped construction,
One end of supporting and mounting bracket is formed with the cavity of the internal gear of the receiving second level transmission mechanism of recess, it is possible thereby to accommodate downlink
Star gear mechanism, to reduce the axial dimension of the sub-unit.
Internal gear 154 is formed in the second end of lower supporting and mounting bracket 162.Internal gear 154 is in the ring gear shape for being formed with internal tooth
Formula, wherein the bottom side of internal gear 154 is in hollow disc-shape and with for allowing the torque output device of pinion frame 1521
The cylindrical type opening 1541 of the 1528 contactless support planetary gears framves 1521 that passes through, and can rotate.Therefore, internal gear 154
Constitute a part for lower supporting and mounting bracket 162.
Installation of the transmission mechanism 150 in supporting and mounting bracket 160 is to be placed in pinion frame 1521 and rotatably it
On planetary gear 1522 fill such as internal gear 154 and beginning.At this point, pinion frame 1521 is filled together with planetary gear 1522
Enter in internal gear 154.Then, centering fixing piece 163 is press fitted into top and the restrictions planetary gear frame 1521 of internal gear 154
Together with the abjection of its upper planetary gear 1522.Then, the without hindrance bearing hole across centering fixing piece 163 of central gear 1523
And contacted with the cooperation of planetary gear 1522, the driven side gear 1512 that is formed together with central gear 1523 together with forming thereon
Cylindrical type boss 1514, which matches to merge with the bearing hole of centering fixing piece 163, limits its radial position.Next first is passed successively
The idle pulley 1513 of dynamic grade 151 is assembled in lower supporting and mounting bracket 162, driven side gear 1512 and driving device 140 are assembled and solid
Due in lower supporting and mounting bracket 162.Upper supporting and mounting bracket 161 is pressed together together with the second driving shaft 1525 formed thereon again
It is assigned in lower supporting and mounting bracket 162.
Finally, transmission lockable mechanism 153 is assembled to relative position and the fixation of lower supporting and mounting bracket 162, to be formed
120 mechanism of integral electric execution unit.Finally, respectively assembling with supporting role up and down in motonsed actuating units 120
Formation motonsed actuating units 120 in shell 110 can be encapsulated into after damping piece.
In addition, motonsed actuating units 120 can also include holder (not shown), setting is for can in internal gear
The support planetary gears frame of rotation is together with the planetary gear placed on it.Holder can be at simple loop configuration, can
The accurate and fixed bottom for being fitted to planetary gear mechanism internal gear in position.In this way, planet can be prevented
Tooth rest assembly is deviate from from internal gear.The holder can be integrated into supporting and mounting bracket.
The characteristics of motonsed actuating units 120 of the present embodiment is to be not only in that installation is simple, and be multiple drivers
Structure component is firm to be fitted in place in integral electric execution unit 120.By this firm mounting means, can effectively improve
Transmission mechanism bears the stability in top load operational process.Meanwhile it by this integrated installation and fixed form, simplifying
The number of parts of transmission mechanism promotes each mechanism relative position precision, while also improving the operational efficiency of transmission device, eliminates
It is mechanically connected the resistance to relaxation risk generated long afterwards when may be because bearing top load.
With vehicle intellectualized rapid development, research tendency of the EMB systems as Automotive By-Wire Control Technology, there is knot
Structure is simple, transmission efficiency, can modular operation, the characteristics of being good for the environment, it will substitution will be existing within following a period of time
Conventional hydraulic braking system, while can also substitute existing EHB systems.
Meanwhile because EMB has the characteristics that distributed arrangement, eliminate the complicated electric control structure of the tradition such as existing ESP and
It is directly integrated in ECU software program.It is easy to and the new-energy automobile with brake energy recovering system is matched, greatly
The new-energy automobile development strategy for having agreed with country, has a vast market development and application prospect.The present invention proposes one kind
EMB motonsed actuating units structures with independent intellectual property right, which, which has, improves product service life, reduces product operation
The advantages of noise.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make these embodiments numerous variations or repair under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the scope of protection of the utility model.
