Description
Technical field
The present invention relates to a kind of automobile parking braking device, especially a kind of transmission device of integrated-type drag-line electronic brake device.
Background technology
The braking during standstill of very most of car adopts pull-out hand brake mostly at present, and its shortcoming has: need the pulling parking brake after one, stopping, increased the labour intensity of chaufeur, muscular labor especially for women's chaufeur; Two, uphill starting the time, need to rely on the driver by hand braking and throttle, the power-transfer clutch three starting smoothly of operation correctly simultaneously, increased the driving difficulty; Three, Parking on the ramp, if parking brake not operation do not put in place, automobile just may sternway on the ramp, causes the accident; Four, parking brake operator handle influences cab space, and parking brake backguy layout is long, difficult arrangement.
Along with increasing of requiring for automobile function, the electronic brake device is employed gradually, and the use of drag-line drg is more extensive, in order to install electronic brake system additional under the situation of not changing original chassis layout, the transmission scheme of integrated-type drag-line electronic brake device seems more practical.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of and replaces power operation with motor, and the transmission device of integrated-type drag-line electronic brake device more quick and portably is provided.
The present invention solves the technical scheme that its technical matters adopts: the transmission device of this integrated-type drag-line electronic brake device, comprise motor, motor is loaded on motor by two mounting screws and installs on the cover plate, motor is installed cover plate and is cooperated the location by its inner ring surface and speed reduction gearing installation housing, and fix with six mounting screws, motor is connected with the motor gear axle, the motor gear axle cooperates with two reducing gear by gear, two reducing gear connect with two reducing gear axles by spline fixes, two reducing gear axles cooperate with four reducing gear, four reducing gear connect with screw shaft by spline fixes, two reducing gear axle left ends are loaded on motor by C type 10x12x10 axle sleeve I and install in the mounting hole of cover plate, two reducing gear axle right-hand members are loaded on speed reduction gearing by C type 12x12x10 axle sleeve and install in the mounting hole of housing, the screw shaft left end is loaded on speed reduction gearing by C type 10x12x10 axle sleeve II and installs in the mounting hole of housing, the middle circle cylinder of screw shaft cooperates with the outer end cap endoporus by C type 14x16x10 axle sleeve, outer end cap utilizes the left end face of cylinder and speed reduction gearing to install that inner cylinder face cooperates on the housing, and outer end cap hold-down bolt and speed reduction gearing installation housing by four band plain cushions and spring shim are fixed, the screw shaft right-hand member is connected by the serration negative thread with special-shaped nut, special-shaped nut right-hand member is connected with the Cable head joint by screw thread, the outer end cap right-hand member is connected with the drag-line stop gear by outside thread, and the outer fitting surface of abnormity nut cooperates with drag-line stop gear endoporus by free-running fit.
As preferably, the tooth form of screw thread transmission is saw thread between described special-shaped nut and the screw shaft.Reason is that saw thread axially is subjected to pulling force in tooth plane vertical screw, and this can improve the ability that screw thread bears axle pressure, and when the nut backhaul, is transmitted by the serration inclined-plane, and required torque is little, can reduce the horsepower output of motor.Special-shaped nut in the worm drive has the face of cylinder of a tangent plane, in transmission process, on the special-shaped nut because to produce friction moment between the screw thread be by drag-line stop gear endoporus the outer fitting surface of special-shaped nut to be produced opposing torque to come balance.Transmission stage, saw thread are that pulling force is born on 3 ° tooth plane at the tooth form oblique angle, bear under the situation of identical pulling force, and it is minimum that the movement resistor moment that saw thread produces contrasts other screw type.
As preferably, what described two reducing gear, four reducing gear adopted is involute spur gear, and the gear that cooperates with four reducing gear on the two reducing gear axles also is involute spur gear, and this kind Gear Processing is convenient, be widely used, and tooling cost is low.
As preferably, motor is installed the installation position that cover plate and speed reduction gearing install housing and is provided with seal ring, and the installation position of outer end cap and speed reduction gearing installation housing also is provided with seal ring, makes integral body be in closed state, and grease can not flow out.
Inventing useful effect is: the present invention replaces power operation with motor, and braking during standstill more quick and portably is provided, and motor is easy to realize automatic control; The employing integrated structure designs, and has reduced the volume of electronic brake system function part, and is easy for installation; Wherein saw thread is adopted in worm drive, and this increase has strengthened the self-locking property of screw thread, reduces the degradation of energy of screw thread backhaul simultaneously; The screw thread transmission adopts screw rod to fix, the nut mode of motion, and adopt structural design to limit the abnormity nut circumferential movement; Adopt gear reduction, the driving efficiency height, degradation of energy is little; The Cable head joint adopts stand alone type, can adapt to different cable connector forms.
