Abstract
The utility model discloses a jaw brake of a hydraulic self-reinforcing disc type, mainly comprising a brake disk, a brake jaw, a brake oil cylinder, a reinforcing oil cylinder, an auxiliary brake oil cylinder, etc. The bottom of the brake jaw is connected with a fulcrum shaft of the brake jaw, a piston of the reinforcing oil cylinder is connected with the side edge of the brake jaw, and an oil pipe of the reinforcing oil cylinder is connected with the auxiliary brake oil cylinder which is connected with the brake oil cylinder through a one-way valve. The utility model has the advantages that greater braking frictional forces can be generated, and simultaneously, the pressure for a braking pipeline can be decreased; reinforcing braking forces of different multiples can be generated through changing the cylinder diameters of the reinforcing oil cylinder and the auxiliary braking oil cylinder; the utility model has good anti-lock braking performance.
Description
The utility model belongs to break, specifically, relates to a kind of structure of hydraulic pressure automatic force-boosting dish-type caliper brake.
Break is the main braking device of vehicle, and a kind of hydraulic pressure dish-type caliper brake is wherein arranged, and its main structure comprises: a brake disc, and a brake calipers that has brake cylinder, brake cylinder is connected with the braking line of automobile.The main deficiency of prior art has: the frictional force that brake cylinder produces is little; The ABS (Anti-lock Braking System) poor performance.
Task of the present utility model provides a kind of technological scheme of hydraulic pressure automatic force-boosting dish-type caliper brake, and it can produce bigger drag friction power, and can reduce the pressure of braking line greatly; Have the ABS (Anti-lock Braking System) performance, make break have higher performance index.
In order to finish above-mentioned task, the utility model adopts following technological scheme: the utility model comprises brake disc 1, brake calipers 2, the brake cylinder 4 that is connected with automobile brake pipeline 3, boosting oil cylinder 5 and auxiliary braking oil cylinder 6; Above-mentioned boosting oil cylinder is fixed on the brake-caliper support, the auxiliary braking oil cylinder places in the brake calipers, the piston of auxiliary braking oil cylinder is connected with braking plate 7, the bottom of brake calipers is connected with the brake-caliper support axle, the piston of boosting oil cylinder is connected with the side of brake calipers, the reinforcement oil pipe of boosting oil cylinder is connected with the auxiliary braking oil cylinder, and the auxiliary braking oil cylinder is connected with brake cylinder by one-way valve 8.
Owing to adopted technique scheme, major advantage of the present utility model is: can produce the much bigger reinforcement frictional force of frictional force that produces than single brake cylinder break, overcome existing caliper disc brake and braked hypodynamic drawback, can reduce the pressure of braking line simultaneously greatly; Can produce the reinforcement braking force of different multiples (with respect to brake cylinder) by changing the cylinder diameter of boosting oil cylinder and auxiliary braking oil cylinder; Has good ABS (Anti-lock Braking System) performance.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of brake calipers of the present utility model.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.In force, the auxiliary braking oil cylinder is loaded on the brake calipers on the position with the brake cylinder symmetry, sees shown in Figure 2.The bottom of boosting oil cylinder is connected with 9 of brake-caliper supports respectively with the bottom of brake calipers.When braking, the piston that the braking oil pressure that is transmitted by braking line promotes brake cylinder produces braking force, simultaneously, brake calipers moves (commentaries on classics) to the direction generation that wheel rotates and moves owing to be subjected to the frictional force of brake disc, at this moment, the piston of compression boosting oil cylinder produces pressure, this pressure acts on by oil pipe on the piston of auxiliary braking oil cylinder, produces reinforcement braking force.Not locked for guaranteeing brake calipers, the pressure that is produced by boosting oil cylinder acts on the auxiliary braking oil cylinder and produces braking force, when this braking force no longer produces reinforcement, the pressure of boosting oil cylinder is acted on the auxiliary braking oil cylinder and the braking force that produces acts on the brake cylinder and the braking force that produces less than brake-pipe pressure.That is to say that when brake-pipe pressure disappeared, the braking force that brake calipers produces also disappeared.
