when the brake is installed, an oil inlet 507 on the main brake pad 5 needs to be connected with an oil outlet pipe on an oil pump (not shown in the figure), and the tightness of the connection between the two is checked, when the brake is in a non-working state, a protruding part of the second cam 603 on the driving shaft 602 is at the bottom end, the second cam 603 does not contact with the rotating plate 2, and because the rotating plate 2 is fixedly connected with the rotating shaft 606, the rotating shaft 606 is fixedly connected with the torque spring 605, the rotating shaft 606 is rotationally connected with the side plate 6, the torque spring 605 provides a torque force to tilt the rotating plate 2 backwards for a certain angle, the main brake pad 5 on the rotating plate 2 is prevented from contacting with a brake disc (not shown in the figure), so as to ensure the normal rotation of the brake disc, when the brake is required, the driving shaft 602 needs to rotate by an external force, and when the driving shaft 602 rotates, the second cam 603 thereon is driven to rotate, the second cam 603 is rotated, the convex part of the second cam 603 rotates towards the direction of the rotating plate 2 at the moment, the second cam 603 contacts the rotating plate 2, the rotating plate 2 receives a pressing force towards the brake pad at the moment, and the main brake pad 5 on the rotating plate 2 is driven to rotate towards the brake disc until the main brake pad 5 contacts the brake disc, so that the braking effect is achieved;

a sliding groove 201 is formed in the outer wall of one side of the rotating plate 2 and corresponds to the movable support 3, and a return spring 202 is fixedly connected to the inner wall of the bottom of the sliding groove 201; the tail end of the top of the reset spring 202 is fixedly connected with the outer wall of the bottom of the movable support 3, the outer wall of one side of the side plate 6 is fixedly connected with a sleeve 4 at a position corresponding to the movable support 3, the inner side wall of the sleeve 4 is slidably connected with a movable pin 401, two groups of telescopic arc plates 501 are movably sleeved on the inner side wall of the main brake pad 5, a telescopic spring 504 is arranged between the two groups of telescopic arc plates 501, a compression spring 505 is fixedly connected with the inner wall of one side of each telescopic arc plate 501, an auxiliary brake pad 502 is fixedly connected with the tail end of one side of the compression spring 505, through holes 506 are formed in the inner side wall of each telescopic arc plate 501 at a position corresponding to the movable pin 401, a sealing bush 7 is arranged in a gap between each telescopic arc plate 501 and the main brake pad 5, sliding blocks 503 are fixedly connected with the outer walls of the front end and the rear end of the bottom of the auxiliary brake pad 502, and limiting grooves are formed in the front inner walls and the rear ends of the telescopic arc plates 501 at positions corresponding to the sliding blocks 503;

the action area of the brake block can be adjusted according to the requirements of a driver per se relative to different road sections, when the road sections are on a normal flat slope and an ascending slope, the action area of the brake block is taken charge of by the main brake block 5, when the road sections are on a descending slope with a larger inclination angle, the auxiliary brake block 502 and the main brake block 5 need to be moved to cooperate with each other, the specific adjustment process is that by starting the oil pump, hydraulic oil in the oil pump enters the main brake block 5 through the oil inlet hole 507, because the sealing bush 7 is arranged at the gap between the telescopic arc plate 501 and the main brake block 5, along with the increasing injection amount of the hydraulic oil, the telescopic arc plate 501 slides along the slide way of the main brake block 5 under the pressure of the hydraulic oil until the telescopic arc plate 501 is completely exposed, then the driving shaft 602 rotates under the same external force, and drives the first cam 604 and the second cam 603 on the driving shaft 602 to rotate together, the second cam 603, at this time, also presses the rotor plate 2, causing the main brake pad 5 thereon to rotate towards the brake disc, and the protruding end of the first cam 604 is directed downward, pressing the movable bracket 3 downward, the movable bracket 3 moves along the sliding groove 201, the ends of the two ends of the movable pin act on the tail end of the movable pin 401 to drive the movable pin 401 to slide in the sleeve 4 towards the auxiliary brake pad 502 to push the auxiliary brake pad 502 out, because the auxiliary brake block 502 is provided with the slide block 503, the slide block 503 is mutually sleeved with the limit groove on the telescopic arc plate 501, the stroke of vice brake block 502 is spacing for the effect outer wall of vice brake block 502 is in same terminal surface with the effect outer wall of main brake block 5, and vice brake block 502 and main brake block 5 together act on the brake disc this moment, have increased the brake area of action, have improved frictional resistance, do benefit to the brake of downhill path highway section more, adjust the area of action of brake block through above-mentioned structure and adapt to different highway sections of traveling.

The working principle is as follows:

the brake is in a non-working state;

the rotating plate 2 keeps a backward slight-warping state through the rotating shaft 606 and the torque spring 605, the joint of the main brake pad 5 on the rotating plate 2 and a brake disc is avoided, the normal rotation of the brake disc is ensured, the convex end of the first cam 604 on the driving shaft 602 is transversely arranged, and the convex end of the second cam 603 is vertically arranged, so that the normal work of the brake disc is not influenced;

under the brake operating condition:

the external force drives the driving shaft 602 to rotate, so that the convex end of the second cam 603 on the outer side of the driving shaft rotates towards the rotating plate 2, and the rotating plate 2 receives the extrusion force to drive the main brake pad 5 on the side wall to rotate so as to clamp and fix the brake disc;

the working state of the brake for the downhill road section is as follows:

when meetting the great downhill path of gradient, need will hide the vice brake block 502 expansion in the main brake block 5, the effective area of increase brake block, input hydraulic oil toward main brake block 5 through the oil pump, force flexible arc plate 501 to expand through the oil pressure, rethread first cam 604 pushes down movable support 3 for vice brake block 502 is pressed before the removable pin 401, with its ejecting and main brake block 5 cooperation coact on the brake disc, play better braking effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
