Abstract
The utility model discloses a parking brake electronic actuating mechanism which comprises a machine casing (11). A motor (10) is arranged in the machine casing and is connected with a female screw (15) through a motor transmission assembly (1). The female screw (15) is connected with a male screw (20), and the other end of the male screw (20) is provided with a drag cable removing device (29). According to the parking brake electronic actuating mechanism, the female screw is controlled by the motor to rotate to drive the male screw to enable the male screw and the female screw to be close to each other or separated from each other, so that two parking brakes to work or stop working simultaneously. The parking brake electronic actuating mechanism achieves electrically parking of an automobile, is fast in reaction speed and large in pull force, obviously improves the effect of parking brake, and increases safety performance of vehicles.
Description
Technical field
The present invention relates to brake system of car, specifically relate to the actuating unit that is applied to parking braking system of automobile.
Background technology
At present, parking braking system of automobile is generally mechanical type parking brake, and its up-and-down movement by manual control pull bar is realized parking function.For the chaufeurs such as weakling, senior people, women, manually pulling force is limited, and capability of reaction is also slower, thereby has affected automobile parking effect and safe driving.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and a kind of braking during standstill electric actuator that can realize automatically that automobile is stayed is provided.
Purpose of the present invention realizes by following technical solution: the braking during standstill electric actuator, comprise casing, and in the described casing motor is housed, this motor links to each other with female screw rod by the motor-driven assembly; Described female screw rod links to each other with male screw rod, and the drag-line decontrol is housed on the other end of this public affairs screw rod.
After adopting the present invention, an other end of male and female screw rod is connected with the left and right drag-line that drives Parking Brake separately, driven by the rotation of the female screw rod of electric machine control male screw rod make the male and female screw rod adjacent to each other or away from, thereby two Parking Brakes are worked or releasing work simultaneously.It has realized electronic automobile in moving, and speed of response is fast, pulling force is larger, has obviously improved the effect of braking during standstill, has increased the safety performance of vehicle.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of braking during standstill electric actuator of the present invention.
Fig. 2 be the left drag-line of Fig. 1, cable-tension sensor with drag-line decontrol (backsight) between the structural representation that is connected.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
With reference to Fig. 1, Fig. 2, braking during standstill electric actuator of the present invention (can claim actuator again) comprises casing 11, and motor 10 (having contained deceleration) is housed in the described casing 11, and this motor 10 links to each other with female screw rod 15 by motor-driven assembly 1; Described female screw rod 15 links to each other with male screw rod 20 (this male screw rod 20 is threaded connection mode and is contained in female screw rod 15), and drag-line decontrol 29 is housed on the other end of this public affairs screw rod 20.
Wherein, described motor-driven assembly 1 comprises and intermeshingly is contained in the main gear 12 on the motor shaft and is contained in driven wheel 13 on female screw rod, between described driven wheel 13 and the female screw rod 15 by spline-shaped link to each other (it is interior that this mother's screw rod 15 is through driven wheel 13).
In order to respond to mechanism of the present invention to the pulling force size of drag-line, (left-hand) side of described drag-line decontrol 29 is equipped with cable-tension sensor 23, it is connected with Zola's rope 19 of this electronic formula car emergency brake system by cable-tension sensor 23, and 15 of female screw rods are connected with the right drag-line 18 of this electronic formula car emergency brake system.The induction cable-tension is determined by the pressure setting scope of cable-tension sensor.
(exhaust no electricity such as power supply) when described drag-line decontrol 29 occurs electrical accident for Parking Brake in the Parking situation, motor 10 can not rotate and keep the Parking state in this situation, then needs artificial releasing.Described drag-line decontrol 29 comprises releasing case 24, is contained in the rotor 26 that is associated son 30 (have on it and be associated groove 33), removes drag-line 28, links to each other with releasing drag-line 28 of removing interior releasing 25 of case, being connected with Zola's rope 19, rotor 26 is contained in respectively the positive back side of removing case 24 with removing son 25 for coaxial link to each other (both can be connected by the spline pin for this), removes son 25 and is associated being associated groove 33 phase embeddings (sealed) or breaking away from (release) on the son 30.Generally, releasing 25 of removing in the case 24 is communicated to female, male screw rod 15,20 with the cable-tension that being associated of groove 33 produce that is associated that is associated on the son 30 that is connected on Zola's rope.When motor lost efficacy manually releasing, spur to the left the releasing drag-line 28 on Fig. 1, rotor 26 clickwises, remove son 25 also to rotate along clockwise direction and be associated groove 33 and break away from, the son 30 that is associated that is connected with Zola's rope 19 is disengaged, in the time of the tension force vanishing of Zola's rope 19, the also vanishing of right drag-line 18 tension force that is connected with female screw rod 15.
As shown in drawings, principle of work of the present invention is: pass through main gear 12 rotational driving gears 13 by motor 10.From the spline of driven wheel 13 throughs be connected mutually along the axial spline of female screw rod 15 peripheries, driven the rotation of female screw rod 15 by the rotation of driven wheel 13.Spline, spline 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 male screw rod 20, right drag-line 18 separately, the rotation of female screw rod 15 drives male screw rod 20 and Zola's rope 19 simultaneously, make left and right drag-line 19,18 adjacent to each other or away from, impel left and right Parking Brake that automobile two trailing wheels are realized braking during standstill.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.
Consist of the electronic formula car emergency brake system by left and right sides Parking Brake, left and right sides drag-line and braking during standstill electric actuator, drive left and right drag-line by the braking during standstill electric actuator and impel left and right Parking Brake that automobile two trailing wheels are realized braking during standstill.The present invention only need click the knob of control machine operation can easily realize automobile parking braking.
