Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A structure for vehicle electric brake final controlling element, as shown in Figure 1.
Power resources are the motor 2 be encapsulated in motor housing body 1, motor 2 is DC Brushless Motor, motor housing body 1 is connected by fastening screw trip bolt with Rigid Gear of Harmonic Reducer 3 and support 4, wherein motor housing body 1 and the bolt hole of Rigid Gear of Harmonic Reducer 3 are not containing the through hole of screw thread, and the bolt hole on support 4 is the through hole containing screw thread.Support 4 is fixedly connected with break caliper 5 by locking nut 8 again.
The power of motor 2 passes to harmonic speed reducer by motor shaft 15, and wherein motor shaft 15 is directly connected by driving key 14 with the harmonic generator 18 of harmonic speed reducer, and the rotary motion of transferring power and transmission motor 2.
Fig. 2 is the structural representation of harmonic speed reducer, and harmonic speed reducer is made up of Rigid Gear of Harmonic Reducer 3, flexbile gear 16, thin-wall bearing 17, harmonic generator 18.Rigid Gear of Harmonic Reducer 3 is inside engaged gear, flexbile gear 16 is external gear pump, harmonic generator 18 is oval, force flexbile gear 16 to produce resiliently deformable after loading harmonic speed reducer and form ellipticity, flexbile gear 16 gear teeth at major axis two ends place insert in Rigid Gear of Harmonic Reducer 3 gear grooved, become complete engagement.When harmonic generator 18 rotates continuously, flexbile gear 16 and Rigid Gear of Harmonic Reducer 3 gear teeth constantly engaging-in, nibble out, produce side set motion and realize Movement transmit; And its minor axis place obtains two wheel gears does not contact completely, be in disengaged condition.
Also comprise the motor 2 be arranged on outside this brake actuator, motor 2 is fixed by screw and support 4 and Rigid Gear of Harmonic Reducer 3,
Motor 2 is by motor shaft 15 outputting power and moment of torsion.
Rigid Gear of Harmonic Reducer 3 is fixed with motor housing body 1 and support 4 bolt, flexbile gear 16 connects transmitting torque with the feed screw nut 7 of ball screw 6 by fastening screw trip bolt 13, and the moment of torsion sent by motor 2 increases square effect by the deceleration of harmonic speed reducer and is delivered in ball screw 6 pair.Ball screw 6 is hollow, built-in feed screw nut 7, and feed screw nut 7 and ball screw 6 form ball screw framework.Feed screw nut 7 is provided with groove, and support 4 has protruding this groove intermediate gap that embeds to coordinate, and bears the axial force of feed screw nut 7, prevents feed screw nut 7 axial motion.Feed screw nut 7 is connected by multiple steel ball with ball screw 6, has feather key 9 between ball screw 6 and support 4, so do not channel bit phenomenon when ball screw 6 moves; Support 4 contacts with the left end of ball screw 6, makes ball screw 6 can not excessively movement when oppositely mobile, limits the displacement of the reverse movement of ball screw 6.Ball screw 6 promotes straight line pushing block 10 and braking brake pad 11 is applied on brake disc 12, produces braking clamping force.
What break caliper 5 adopted is traditional disc brake with floating caliper caliper structure, the high order end of housing is changed as columniform cavity, whole brake actuator extrudes brake disc 12 by brake strip 11 to produce braking force, braking the sassafras sheet 11 that rubs is installed in the draw-in groove of break caliper 5, brake disc 12 and hub for vehicle wheel are fixed, locking nut 8 is mechanical locking device, prevent the axial motion of support 4, by the straight line motion of ball screw 6, promote straight line pushing block 10, straight line pushing block 10 promotes the braking sassafras sheet 11 that rubs and extrudes brake disc 12, and braking force produces.Straight line pushing block 10 is arranged in the cavity of break caliper 5.
Harmonic speed reducer can buy general or standard harmonic reducer assemblies according to reduction speed ratio, need not design separately or manufacture specially; The built-in rotary angle transmitter of motor 2, can measure the angle position of motor 2, thus realizes the clearance self-regulating function after friction facing wearing and tearing.
When implementing braking, power is passed to harmonic speed reducer by motor shaft 15, driving key 14 by motor 2.Now the flexbile gear 16 of harmonic speed reducer rotates, and drives the feed screw nut 7 of ball screw 6 to rotate, and steel ball promotion ball screw 6 produces axial displacement to the right thus, and the braking brake pad 11 promoting left side is eliminated to brake disc 12 is close to left hand brake gap.This rear brake caliper 5 is moved to the left, and the braking brake pad 11 on right side is eliminated to brake disc 12 near to right side brake clearance.After this, the braking brake pad 11 of both sides to be pressed on brake disc 12 simultaneously thus to implement braking.
When brake off, motor 2 suitably reverses, ball screw 6 oppositely movement, and both sides braking brake pad 11 and brake disc 12 unclamp, brake release.
When brake off, motor 2 reverses an angle determined all the time, just can realize brake clearance from conditioning function.Brake clearance calculation of initial value when this angle determined can not worn and not torn by braking brake pad 11 obtains.
In braking process, Rigid Gear of Harmonic Reducer 3 is by being bolted with support 4 and motor housing body 1, maintain static, harmonic generator 18 is connected with motor shaft 15 by driving key 14, follow motor shaft 15 to rotate, thin-wall bearing 17 extrudes the flexbile gear 16 of harmonic speed reducer simultaneously, flexbile gear 16 engages with Rigid Gear of Harmonic Reducer 3 and own rotation, feed screw nut 7 and flexbile gear 16 are connected and fixed by lock screw 13, drive feed screw nut 7 also rotates by flexbile gear 16, ball screw 6 straight line motion under the restriction of feather key 9 simultaneously, feather key 9 moves linearly in guide key groove.Ball screw 6 promotion straight line pushing block 10 promotes braking brake pad 11 and extrudes brake disc 12.
