Description
Technical field
The present invention relates to a kind of electrodynamic type parking brake installed in the car, more particularly it relates to a kind of
Double towed electric parking brakes of trail-type drag-line.
Background technology
In general, electric parking brake（EPB）Wheel of vehicle is applied retardation force to, to prevent wheel from rotating, so as to
So that vehicle will not be moved in parking.Tradition machinery formula parking brake occupancy parking brake box space is big, since national legislation provides to drive
Room considers that it is firmly most suitable that the right hand, which pulls the hand brake, and the arm strength of men and women driver is that have big cell on the left side, from ergonomics
Other, it is laborious operating process that the position of brake bar, which is moved at the 8th engagement tooth socket of ratchet,.Such as application No. is
The utility model patent of CN201220740326.4 discloses a kind of engineering machinery Zipper-type parking brake, and vehicle bridge is equipped with dynamic
Disk, two calipers, two calipers that brake is equipped with parallel distribution are sleeved in installation bolt；In the two calipers, it is equipped with
Two friction plate assemblies, the two friction plate assemblies press from both sides brake disc in-between；Two calipers are passed through with turnbuckle；It draws again
One end connection rotary shaft of tight bolt, and ball bearing mechanism is installed in this one end of turnbuckle, ball bearing mechanism set two it is annular
Baffle is equipped with ball grooves on the opposite face of two ring baffles, and ball is set in ball grooves, and the groove depth of ball grooves is formed by shallow
To deep variation.Tradition machinery formula parking brake acts on rear revolver and the pulling force of rear right wheel is of different sizes, leads to rear revolver and rear right
The braking moment of wheel is of different sizes；In parking on 20% standard ramp it is difficult to ensure that the stability of parking, judgement vehicle parking are steady
The qualitative braking moment size and the degree of consistency for being primarily to see rear revolver and rear right wheel.
New-style electronic parking braking system of automobile is by left and right parking brake, left and right zipper and parking brake actuator
Composition drives left and right zipper that left and right parking brake is promoted to realize parking to two trailing wheel of automobile by parking brake actuator
Braking.Such as a kind of parking brake actuator of disclosure of the invention application No. is CN201210315261.3, including casing, electricity
Mechanical, electrical machine transmission component, female screw rod, one end of mother's screw rod release device with zipper by left male screw rod and are connected, the mother
The other end of screw rod is connected by Yougong screw rod with zipper tension sensor, and the hand of thread spiral on the left and right public screw rod
On the contrary.The other end of the left and right public screw rod is respectively connected with the left and right zipper for driving parking brake, by female screw rod
Rotation drives left and right public screw rod toward or away from one another, so as to which two parking brake be made to work or release work.Above-mentioned patent
Motor drive component is driven to rotate female screw rod by electric motor starting, Zola is pulled to lock by male screw rod respectively by female screw rod,
Zipper releases device and pulls right zipper, so as to which left and right parking brake be made to work.Two screw rod rotations are driven by a nut,
Nut does a movement of direction of rotation, and screw rod tenses or unclamp a movement in direction；Or drive two by a screw rod
A nut rotation, screw rod do a movement of direction of rotation, and nut tenses or unclamp a movement in direction.Its shortcoming
It is, a nut drives two screw rods or a screw rod that the design of two nut movements is driven to reduce left and right cable movement
Consistency, affect parking effect, reduce the security performance and reliability of vehicle.
Invention content
The tension imbalance that is generated for the both ends for overcoming female screw rod in the prior art to left and right zipper can not achieve together
Step stays dynamic or left and right and stays the shortcomings that dynamic unbalanced inconsistent, and the present invention provides a kind of new productions with good parking feature
Product, i.e., a kind of double trail-type towed electric parking brakes of drag-line, an EPB electronic cutting is installed in parking brake box appropriate location
It closes, detains EPB switches upwards with finger, you can to realize tension full content, action is completed to enter parked state.Make at this time
