Working principle of the present invention is:
When break is braked (rise), need make nut piston 21 be moved to the left until, make the electromagnet 193 of being controlled by electronic control unit 0 unclamp cone push rod 192; Cone push rod 192 moves upward under the effect of Compress Spring 194, and cone push rod 192 is withstood cylindrical gears 4, and the second leading screw 3 be connected with cylindrical gears 4 can't be rotated, and nut piston 21 is because the rubbing action of seal ring 20 can not rotate yet simultaneously; Now just can promote reinforcement linkage mechanism 8 by motor 15, make the fork of reinforcement linkage mechanism 8 promote screw rod bushing 5, the second leading screw 3, nut piston 21, after final the promotion, friction plate 22 is pressed close to brake disc 2; Meanwhile, another fork of reinforcement linkage mechanism 8 promotes unsteady caliper 7 by right connection hinge 11 and moves in the opposite direction, drive front side floating clamp 1 and promote fixed front friction plate 23 on it and also press close to brake disc 2, so just produced braking moment, realize the braking to wheel;
During backhaul, disable motor 15, make the fork return of reinforcement linkage mechanism 8, and fork drives the second leading screw 3 and moves right together with nut piston 21, releasing brake; Make electromagnet 193 hold cone push rod 192, cone push rod 192 is separated with cylindrical gears 4, now the second leading screw 3 can freely rotate;
Because this break is disc brake with floating caliper, if rear friction plate 22 does not does not wear and tear, the axial return amount of nut piston 21, the second leading screw 3 and screw set 5 is the setting gap L, sets gap L and is the gap between rear friction plate 22 and brake disc 2;
If rear friction plate 22 weares and teares, the axial return amount of screw set 5 should be setting gap L+△, the wear extent that △ is rear friction plate 22, and L is the gap sum of two floating clamps and brake disc 2 herein; And nut piston 21 mobile L under the effect of seal ring 20, at this moment needing nut piston 21 and the second leading screw 3 to produce the backlash compensation of △ could friction compensation sheet 22,23 and the wearing clearance △ of 2 of brake discs, therefore the pass between the axial force F 2 of the frictional force F1 of needs assurance seal ring 20 and nut piston 21 and the second leading screw 3 and nut piston 21 is: F1 > F2, could in compensation process, guarantee, thereby the second leading screw 3 and nut piston 21 rotate and produce nose balance amount △, and nut piston 21 does not relatively rotate with unsteady caliper 7.
The present invention is provided with gap adjusting mechanism 19, utilizes coordinating between cylindrical gears 4 and automatically controlled cone push rod 192, realizes the unidirectional control to the second leading screw 3.During rise, electromagnet 193 unclamps cone push rod 192, and cone push rod 192 is withstood cylindrical gears 4, the second leading screws 3 and can't be rotated, thereby guarantees axial being rigidly connected; During backhaul, electromagnet 193 holds cone push rod 192, the second leading screws 3 can axial rotation, thereby the wear extent of friction plate 22 after compensation realizes backlash compensation.
Gap adjusting mechanism 19 of the present invention also has the function of stopping brake, when the needs stopping brake, only need be under the prerequisite of existing service brake, press a set of switch of being controlled by electronic control unit 0 in addition, when service brake, in the situation of motor 15 in stall, lasting braking force output is arranged, while needing stopping brake, only motor 15 need be stopped, leading screw push rod 9 will keep required braking distance always like this, thereby guarantee the braking distance of 2 of friction plate 22,23 and brake discs; On the other hand, when stopping brake, electronic control unit 0 is controlled the attraction that electromagnet 193 discharges cone push rod 192, makes cone push rod 192 keep withstanding cylindrical gears 4 always, thereby guarantee can not relatively rotate between the second leading screw 3 and nut piston 21, thereby realize parking brake function.
The reinforcement effect of reinforcement linkage mechanism 8 of the present invention is fairly obvious, as shown in Figure 3,
The axial force that the Input Forces F of reinforcement linkage mechanism 8 is leading screw push rod 9, the axial force that ouput force Fo is nut piston 21, the thrust of two connecting rods of the reinforcement linkage mechanism 8 of one-tenth V-type is N, connecting rod and horizontal angle are θ, the fork overall length of reinforcement linkage mechanism 8 is L, distance between left connection hinge 26 and fixed hinge 13 is l, and the stressed relation according in above-mentioned geometrical relationship and linkage mechanism can obtain:
If get L/l=3, θ=5 °, Fo=17.15F.Can find out to there is into the relation of multiple between Fo and F.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacement all should be included in protection scope of the present invention.
