The upper and lower end of described swing arm is respectively equipped with mounting hole and lower mounting hole, penetrates a heterotypic bolt in described upper mounting hole, and an end of described heterotypic bolt is connected with fore stay, and the other end is connected with right drag-line, and described lower mounting hole is connected with Zola's rope.
Described heterotypic bolt is with a square bolt cap and a cylindrical portion, and described cylindrical portion penetrates in the upper mounting hole of described swing arm; Described square bolt cap is provided with screw, and the inner of described fore stay penetrates the screw of heterotypic bolt by double-screw bolt, and fore stay and square bolt cap is fixed with two nuts in the both sides of square bolt cap; The ring-type fitting sleeve of described right drag-line by its end is loaded on described cylindrical portion and is connected with heterotypic bolt, and the outer end of heterotypic bolt cylindrical portion is provided with spring cotter.
The center of described upper mounting hole and lower mounting hole equates to the distance at rotating shaft axis hole center.
Described swing arm is arranged at the position of departing from Vehicle Symmetry Center.
Beneficial effect of the present invention is:
1. the present invention, can allow left and right drag-line sense of motion mutually on the contrary each drag-line substantially remain on one and highly work, the power of left and right drag-line and stroke keep unified simultaneously, can not produce the problems such as braking force is unbalance, thereby be conducive to the control of parking brake by this mechanism, and make the work coordination of three drag-lines;
2. the stroke of the left and right drag-line of this case equates, so swing arm can be arranged at the position of departing from Vehicle Symmetry Center, like this, has just solved the inconvenient such problem of center of symmetry that swing arm is arranged at vehicle due to layout.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the mounting structure schematic diagram of swing arm and heterotypic bolt;
Fig. 3 is the structural representation of swing arm.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3.
a kind of Parking drag-line synchronous adjusting mechanism, comprise fore stay 1, Zola's rope 2, right drag-line 4, a described left side, right drag-line 2, 4 outer end respectively with a left side, the drg of right wheel connects, the outer end of described fore stay 1 is connected with parking brake, also comprise the support 7 that is arranged on cross member of frame, fore stay 1, Zola's rope 2, the sheath of right drag-line 4 is fixed on support 7, the middle part of described support 7 is provided with swing arm 5, described swing arm 5 is connected with support 7 by rotating shaft 6, the inner of described fore stay 1 and right drag-line 4 all is connected in the left and right sides that the upper end of swing arm 5 and fore stay 1 and the outer end of right drag-line 4 lay respectively at described swing arm 5, the inner of described Zola's rope 2 is connected in the lower end of swing arm 5, described Zola's rope 2 and fore stay 1 are positioned at the homonymy of swing arm 5, a described left side, right drag-line the inner equates to the distance at rotating shaft 6 centers.
In this case, adopted fore stay 1, Zola's rope 2, right drag-line 4 to be connected with swing arm 5, driven fore stay 1 by pulling parking brake, thus realize the Zola lock 2 with right drag-line 4 to drawing, thereby control the drg of left and right wheel, realize the braking during standstill of left and right wheel.Only needing to realize thus the motion of 1 one directions of fore stay, just can drive simultaneously the left and right drag-line toward opposite direction motion, wherein fore stay 1 is identical with right drag-line 4 sense of motions, fore stay 1 is opposite with the sense of motion of Zola's rope 2; Because the inner distance to rotating shaft 6 centers of left and right drag-line equates, therefore, the stroke of left and right drag-line also equates.
The upper and lower end of described swing arm is respectively equipped with mounting hole 9 and lower mounting hole 10, penetrate a heterotypic bolt 3 in described upper mounting hole 9, one end of described heterotypic bolt 3 is connected with fore stay 1, and the other end is connected with right drag-line 4, and described lower mounting hole 10 is connected with Zola's rope 2.
Described heterotypic bolt 3 is with a square bolt cap and a cylindrical portion, and described cylindrical portion penetrates in the upper mounting hole 9 of described swing arm 5; Described square bolt cap is provided with screw, and the inner of described fore stay penetrates the screw of heterotypic bolt 3 by double-screw bolt, and fore stay and square bolt cap is fixed with two nuts 11 in the both sides of square bolt cap; The ring-type fitting sleeve of described right drag-line by its end is loaded on described cylindrical portion and is connected with heterotypic bolt, and the outer end of heterotypic bolt cylindrical portion is provided with spring cotter 8.Due between fore stay 1 and heterotypic bolt 3 for being threaded, and be provided with the fastening nuts location, therefore, can by adjusting the position of bolt and nut, adjust the elasticity of fore stay 1.
The center of described upper mounting hole 9 and lower mounting hole 10 equates to the distance at axis hole 12 centers of rotating shaft 6.
Because the stroke of having explained left and right drag-line in previously described technical scheme equates, therefore described swing arm 5 can be arranged at the position of departing from Vehicle Symmetry Center, like this, just solved the inconvenient such problem of center of symmetry that swing arm is arranged at vehicle due to layout.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
