Description
Technical field
The invention belongs to motor vehicle braking systems manufacturing technology field, specifically, relate to a kind of electronic parking actuator for motor vehicle braking system.
Background technique
At present, in Motor Vehicle parking braking system, especially, in electronic brake system, forceps major Integral electronic Parking Brake function is many, easy for installation, becomes development trend.。Unique power resources of the electric parking brake of this structural type are motors, and described motor, through driving mechanism, passes to brake caliper assembly by power, and then completes the parking braking to vehicle.Described motor, driving mechanism and housing be totally called electronic parking actuator.In electronic parking actuator, conventionally adopt Planetary Gear Transmission to complete decelerating through motor, because planetary pinion volume is little, lightweight, velocity ratio is large, therefore become increasing producer and select.The ride quality of this electronic parking actuator directly has influence on parking quality and user's impression.
In prior art, many pieces of documents all disclose said structure form, for example many pieces of following Chinese patent literatures:
1), Chinese Patent Application No. is 200680000787.5, name is called the patent of " electric braking actuator ", this patent has adopted multi-stage planetary gear mechanism to complete the deceleration to motor.
2), Chinese Patent Application No. is 200710156334.8, its name is called " a kind of vehicle electronic brake system actuator ", this patent has adopted involute planetary gear gear mesh decelerating through motor.
3), Chinese Patent Application No. is 200810171707.3, its name is called " caliper attaching type electrical parking brake in vehicle ", this patent has adopted primary planet pinion driving mechanism.
Therefore, in above-mentioned patent documentation, all disclose " motor, as power resources, adopts planetary gear speed-reduction " and gradually become the main flow of forceps major Integral electronic parking actuator.In order to solve the technical problem that electronic parking actuator size is large, specific practice be motor with planetary gear mechanism point both sides by parallel installation.Mounting type must be passed to planetary gear speed-reduction motor power by a driving mechanism like this, and such structural type must be brought following two technical problems:
Is 1, motor power passed to planetary gear mechanism in which way?
The performance of this kind of drive of problem 2, by which kind of structure guaranteeing.
In order to have solved the problems referred to above 1 and problem 2, following technological scheme is disclosed in prior art, be that Chinese Patent Application No. is 200780005928.7, name is called " electric brake actuator of reducing noise ", this patented technology scheme adopts the kind of drive between motor and planetary pinion to adopt belt transmission form, proposed " distance between motor shaft and gear shaft is by a rigid spacers " fixing, rigid spacers is S shape or Z-shaped.
But the insoluble technical problem that the technological scheme in the prior art still exists:
1), the stressed rear of the rigid spacers of the prior art scheme easily deforms;
2), the prior art scheme is failed to solve spacer element and is out of shape the motor shaft and the axial uneven technical problem of planetary pinion that cause;
3), the prior art scheme makes the centre distance of spacer element and motor shaft, epicyclic transmission mechanism main shaft all can not obtain the technical problems such as well assurance.
In addition, Chinese Patent Application No. of the prior art is 200810171707.3, name is called " caliper attaching type electrical parking brake in vehicle " and can solves the above-mentioned technical problem of part, the orientation type that the prior art scheme adopts is " integrated casing "---motor and planetary pinion all lean on housing location, but the prior art also exists many technological deficiencies:
1) product cost is high: housing has locating function, has increased the accuracy of manufacturing of housing; Housing is semi-surrounding mechanism, can only all transmission component be assembled from a direction, higher to matching requirements, and product cost is increased.
2) be subject to ectocine large: housing is subject to external influence larger, also caused whole final controlling element to be subject to the impact of environment larger.
3) gear shaft terminal upper-lower position is inconsistent: integral housing can well be determined the Gear center distance of housing one end, but is difficult to guarantee that the upper and lower gear shaft terminal of " housing " " housing lid " center is consistent: by the periphery of " housing lid ", form groove and housing and connect to guarantee that gear accurately locates.And " housing " and " housing lid " fitting surface shape and too little very difficult in full accord, manufacture view difficulty is very large.Even if they have accomplished that " housing " and " housing lid " well coordinates, and in the welding process of " housing " and " housing lid ", the plastics of " housing " and " housing lid " surface of contact form liquid state because melting, and at this moment inconsistent phenomenon is very obvious, and are difficult to control.At this moment " the clutch shaft bearing support " in " housing lid " and " the second bearing supporting body " be also difficult to and the corresponding clutch shaft bearing support of housing " and " the second bearing supporting body " be consistent.
