Description of the invention (9) Piece 21 3 and the brake pad body 1 7 are pulled closer by elasticity 'and the frictional contact surface of the pendulum: X 丄'And-from each other to create a gap, while maintaining close contact. The surface friction contact surface ㈣ will not produce the elastic element X, Mo that makes the friction contact surface s and the plane of the pendulum friction contact: ::, the animal is ready to form tight to punch or bend, etc. ^: elasticity The shape of the sheet metal material is hand-opened to form J. As shown in Figure 4 or Figure 5, the ends on the two sides are bent into: outer cymbals, which can be engaged with the brake pad body 17 and i. The circular holes 42 and 42 forming a circular shape are formed at the ends and are perforated to form four buckle pieces 43 which are buckled; U-shaped upright bent side fixed elements 191 and 211 of the month. Since the centripetal joints 19 and 17 can be snapped around the m /, the brake pad bodies 17 and 17 form a movable side element I ", 2 fixed side elements 191, 211 which can be clamped freely.

Description of the invention (10) If the body 9 forms a temporary parallel swing, it will be kept pressed evenly, so it can be compressed. Shows stability and stability: When the brake is not applied, the brake pads 16, 16 = ㈣ power. Small) uniform spacing, and because it will not float, take a small limit (micro = brake pads 16, 16 have better support during this braking, = surface contact breaks the brake body 9, and with the electromagnet ^ 〇 Reality of dragging: significantly reduce the change in the distance between two movements caused by part contact, and even when braking; 7 6 7 the distance between the gaps becomes narrow, but with the elastic element side element 1 9 1 2.

The bracket 8 which bears the tangential force Ft of the two brake pads 6, 7 is shown in Fig. 13a, and its overall shape is gate-shaped. Furthermore, as shown in FIG. 13c, a groove 11 is formed into which the braked body 9 can be inserted, and the left and right feet 12, 12 are divided into two due to the existence of the groove 11. In addition, the lower ends of the left and right feet 12, 12 are respectively formed with press holes 1 3, 1 and 3 with screw holes. Since the bolts are screwed into the screw holes, the bracket 8 can be fixed to the fixing member 10 (such as the first Figure and Figure 2). Further, the brake pads 6 and 7 are held in the door-shaped bracket 8 12 and the inner space 15 around the mouth. On the four corners ⑥ of the rectangular =: 6 7, near the inside of the bracket 8, a sliding surface 18 is provided for the pressing operation direction of the brake pads 6 and 7 toward the brake pads 6 and 7. In this way, a pair of brake pads 6 and 7 are slid around in the bracket 8 in the direction in which the brake pads 6 and the actuator can move: two: the orientation system is in a stationary state, and the bracket 8 receives the cutting force Ft The square car plates 6, 7 form a rectangular plate shape, which can make the bracket fall: kill: force, this can get a more stable clamping effect. Jiao Luo Chengwen Next, we will refer to the plate body 2 and so on, referring to the more specific 1 in the drawing. As shown in the first figure, the plate body 2 is slightly diamond-shaped.

The guide rods 4 and 4 are respectively inserted into the holes 32 and 33 on the two ends of the frame 8 shown in Figure 3a. The outer surface of the inner surface of the hole 32 is frictionally movable. Moreover, in FIG. 6, '01 & υυ sets the sliding bushing 33 in the hole 32, so the friction movement will be more like this, which is composed of the electromagnet 1, the plate-shaped body 2 and the guide rod 4. The component '11 Shun = can be mounted on the handle 8 with small size floating. ”During braking, as the brake pads 6 and 7 generate a strong reaction force when pressing the braked body 9 (in the direction of the arrow A), the reinforcing rod 27 can prevent the upper part of the diamond plate 2 from falling down, and can prevent the plate from falling down. The body 2 falls in a direction in which the distance between the electromagnets 1 decreases. In other words, the other function of the reinforcing rod 27 is that it can function as a protruding rod. This is shown in Figure 1 'in the diamond-shaped plate body The left and right top ends of 2 form a pair of small protruding pieces 34, 34; on the other hand, in FIG. 4, the left and right ends of the upper side of the bracket 8 also form small protruding pieces 35, 35. , Forming screw holes 3 5 a and 3 5 a respectively.

The alignment center of U and the restricting member 37 can obtain the air gap between the brake pads 16 and 16 of the vehicle plates 6 and 7 between the component 9 and the brake member 9 in particular.内 ， 日 蒋 骚 # As shown in the figure, inserting the bolt 38 into the compression coil spring can obtain a more structure: 3 single 6 and: the 37 piece is formed to a smaller size, that is, the second room is early, and the cost can be reduced. . H 1 then said 'because of the concave and convex spherical surfaces of the centripetal joints 19, 21 and the oscillating friction contact surfaces s, s formed between 2 1 2, 2 1 4 , And the flat frictional contact surfaces Q, Q formed between the rear surface of the brake pads 6, 7 and a flat surface are in a state of contact through "skin boost, so no gap will occur :. When not braking, They can ensure an equal recovery amount and maintain the necessary clearance. Therefore, during the braking, the operating sound can be reduced, and the operating sound or dragging sound can be prevented during the ON-OFF switching of the brake. Better coping ability can obtain more powerful braking force. Furthermore, since the gap between the braked body 9 and the two brake pads 6, 7 can be set to the minimum necessary for uniformity, the electromagnet The electromagnetic force exerts its maximum effect.

Page 20 WU826 V. Description of the invention (18) According to the invention δ already contained in the first, second, / iL vd or 4 of the scope of patent application, because of the elastic element X, the brake pads 6, 7 can be 佶 A π 〇1 Yuetian Yu .. The center of the centripetal joint 1 9 and 2 1 is the contact surface S and the flat friction contact surface Q to the bismuth. Therefore, when braking, the brake pads 6 and 7 can be independent of each other. 3 (Limited by the bracket 8 of the tangential force dagger) to ensure an equal amount of recovery. And is it? At the centripetal joints I 9, 21 ', if the bow is temporarily corrected, the parallel gap between 7 and the braked body 9 will be maintained as it is, so the abutting surface will not contact the braked body 9, 3 brakes. έ 之间 β can keep the uniform distance necessary to take small (generally) small, and it will not produce the familiar dragging sound. Furthermore, the noisy sound that occurs when the brake 〇—ding changes every time will also disappear. That is, for the bracket 8 fixed to the fixing element 10, even if the component U generates some offset on the same axis, the offset can be absorbed through the flat friction contact surface Q and the swing head friction contact surface S. The abutment surface 9 of the braked body can be accurately and often brought into contact and separated in parallel in a necessary minimum clearance, which can reduce the operating sound, and at the same time, obtain a strong braking force. Furthermore, the tangential force Ft received from the braked body 9 during braking is received via the bracket 8 and is not transmitted to the plate-shaped body 2 and the guide rod 4, so that the plate-shaped body 2 and the guide rod 4 can be received. The lever 4 and the like are smaller and lighter. Furthermore, since a conventional large block clamp 'can be omitted, a simpler and smaller structure can be obtained as a whole. In particular, the size (thickness) of the left and right widths shown in Figs. 2 and 3 can be reduced. According to the invention described in the scope of patent application No. 2, 3 or 4, since the car plates 6, 7 can be slid and freely disassembled, they can be exchanged, repaired and inspected.
