Description
Technical field
The present invention relates to brake system of car, specifically relate to be applied to the actuating unit of parking braking system of automobile.
Background technology
At present; Parking braking system of automobile is divided into mechanical type and electronic type parking braking; Wherein the electronic type parking braking system of automobile is made up of left and right sides Parking Brake, left and right sides zip and braking during standstill actuating unit, drives left and right zip through the braking during standstill actuating unit and impels left and right Parking Brake that automobile two trailing wheels are realized braking during standstill.
Existing braking during standstill actuating unit (can claim actuator again); Comprise casing, motor, drive of motor assembly, female screw rod; One end of this mother's screw rod connects Zola's lock of electronic type parking braking system of automobile through public screw rod; The other end of this mother's screw rod connects the right zip of electronic type parking braking system of automobile through zip decontrol, zip tension pick-up; Its principle of work is: drive the drive of motor assembly through electric motor starting and make female screw rod rotation, spurred right zip, thereby make left and right Parking Brake work through public screw rod pulling Zola lock, zip decontrol respectively by female screw rod.The two ends that its weak point is this mother's screw rod are to the tension imbalance that left and right zip produces, can not realize staying moving synchronously or about stay moving unbalancedly, influenced the effect of braking during standstill.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, can stay moving braking during standstill actuating unit synchronously to equalization of strain, realization that left and right zip produces and provide a kind of.
The object of the invention is realized through following technical scheme: the braking during standstill actuating unit; Comprise casing, motor, drive of motor assembly, female screw rod; One end of said female screw rod links to each other with the zip decontrol through left public screw rod; The other end of said female screw rod links to each other with the zip tension pick-up through the Yougong screw rod, and the hand of thread spiral on this left and right public screw rod is opposite.
After adopting the present invention; An other end of left and right public screw rod is connected with the left and right zip that drives Parking Brake separately; By the rotation of female screw rod drive simultaneously left and right public screw rod adjacent to each other or away from, thereby two Parking Brakes are worked or releasing work simultaneously.The left and right zip equalization of strain of its generation can be realized staying synchronously moving, and has obviously improved the effect of braking during standstill, has increased the safety performance of vehicle.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description.
With reference to Fig. 1, Fig. 2; Braking during standstill actuating unit of the present invention; Comprise casing 9, motor 10 (having contained deceleration), drive of motor assembly 1, female screw rod 15; One end of said female screw rod 15 links to each other with zip decontrol 23 through left public screw rod 17 ＇, and the other end of said female screw rod 15 links to each other with zip tension pick-up 34 through Yougong screw rod 17, and the hand of thread spiral on these left and right public screw rod 17 ＇, 17 is opposite.
Wherein, zip decontrol 23 is locked 19 with the Zola of this electronic type parking braking system of automobile again and is connected, and zip tension pick-up 34 is connected with the right zip 18 of this electronic type parking braking system of automobile again.Said zip tension pick-up 34 is made up of coil spring 31, permanent magnet 32 (coil spring is on permanent magnet), Hall IC 35, and the size of this zip tension force is determined by the pressure setting range that coil spring bore, sends signal by Hall IC again.
Said drive of motor assembly 1 comprise intermeshing be contained on the motor shaft main gear 11 be contained in the driven wheel 13 on female screw rod, link to each other through spline-shaped (as shown in Figure 4) or spline pin shape or with the form (like Fig. 5, shown in Figure 6) that gear adds linear bearing between said driven wheel 13 and the female screw rod 15.The spline 14 that the center connects in this driven wheel 13 is connected with the spline 16 of female screw rod 15 upper edge peripheral, axial mutually.That is to say that the reception and registration of moment is not restricted to spline between driven wheel and the female screw rod, its spline pin shape or can both pass on the moment of rotation direction with the form that gear adds linear bearing is as long as female screw rod can axially move freely.Therefore, female screw rod needn't place the center of driven wheel, and like the periphery interlock of the secondary female screw rod among Fig. 6 51 and secondary driven wheel 52 and axially can move, this mode is also passable.
Said structure, the rotation that is accompanied by female screw rod 15 is moved left and right public screw rod 17 ＇, 17 on both sides simultaneously, and therefore, when Parking was worked, the number of turns that female screw rod rotates had only the half the of above-mentioned background technology, and it has sensitiveer, the more superior characteristics of responsiveness.Two left and right public screw rod 17 ＇ that reality is mentioned in the example, 17 rotate and again by the drive of female screw rod 15 through driven wheel 13, make these two left and right public screw rod 17 ＇, 17 adjacent to each other or away from.Other type is as shown in Figure 7: drive the rotation of a public screw rod 40 of pair through driven wheel 13, make the female screw rod of two left and right pairs that are connected to its periphery two ends 41,42 adjacent to each other or away from structure also can reach same effect.
Like Fig. 2, shown in Figure 3, when occurring electrical accident for Parking Brake under the Parking situation, zip decontrol 23 (exhausts not) such as power supply, and motor 10 can not rotate and keep the Parking state under this situation, then needs artificial the releasing.Said zip decontrol 23 comprises releasing case 24, is contained in and removes interior releasing 25 of case, lock 19 bonded assemblys with the Zola rotor 26 that is zygote 30 (have on it is to close groove 33), removes zip 28, links to each other with releasing zip 28; Rotor 26 is contained in the positive back side of removing case 24 with removing son 25 respectively for coaxial link to each other (both can be connected through the spline pin for this), remove sub 25 be to be to close perhaps disengaging (release) of groove 33 embedding mutually (sealed) on the zygote 30.
Generally, releasing of removing in the case 24 25 is on the zygote 30 to be that what close groove 33 is to close the zip tension force that is produced to be communicated to left and right public screw rod 17 ＇, 17 with what be connected that the Zola locks.When the motor inefficacy needs artificial the releasing; Spur the releasing zip 28 on Fig. 3 to the right, rotor 26 left-hand revolutions, remove son 25 also along anticlockwise motion and be to close groove 33 to break away from; Like Fig. 2, shown in Figure 3; Locking 19 bonded assemblys with the Zola is that zygote 30 is disengaged, when the Zola locks 19 tension force vanishing, and the also vanishing of right zip 18 tension force that is connected with another root Yougong screw rod 17 among Fig. 1.
Shown in accompanying drawing, principle of work of the present invention is: pass through main gear 11 rotational driving gears 13 by motor 10.The spline 14 that connects from driven wheel 13 centers is connected with the axial spline 16 of female screw rod 15 peripheries in edge mutually, is driven the rotation of female screw rod 15 by the rotation of driven wheel 13.Spline 14, spline 16 have limited female screw rod 15 rotation directions, can move freely along the direction of principal axis of driven wheel 13.The two ends of female screw rod 15 are connected left and right public screw rod 17 ＇, 17 separately; The rotation of female screw rod 15 drives left and right public screw rod 17 ＇, 17 adjacent to each other or be connected with the left and right zip 19,18 that drives Parking Brake separately away from, left and right public screw rod 17 ＇, an other end of 17 simultaneously.Therefore, by the variation of the rotation direction of motor 10, drive the change of the rotation direction of driven wheel 13, female screw rod 15, thereby make Parking Brake work or releasing work.
