[0002] Disc brake is a kind of high-efficiency brake system, mainly by brake disc, brake caliper and brake friction plate and other components.Its working principle is through high-pressure brake oil to push brake block clamping brake disc, to generate braking effect.Disc brake is divided into mechanical type and oil pressure type, wherein oil pressure type disc brake force is acute, maintenance degree is low, but need to pay attention to the compatibility and replacement cycle of brake oil.The advantages of disc brake include short stopping distance, labor saving, no wear and tear of wheel set and good weather resistance;The disadvantage lies in relatively large weight, complex structure and not easy to maintain.

[0003] Brake friction plate is installed on both sides of brake disc through suspension system, and they will gradually wear in long-time use process.As brake caliper and brake disc are installed on the inner side of wheel hub, so users usually cannot directly observe the wear condition of brake friction plate.In order to check the wear condition of brake friction plate, it needs to use lifting machine to lift the automobile, so that brake friction plate can be checked.Due to the inconvenience of this process, users often cannot judge whether brake friction plate needs to be replaced in time, so that the best replacement opportunity can be missed. UTILITARY MODEL CONTENTS

[0004] The utility model aims at providing automobile brake structure suspension structure to solve the problem that whether brake friction plate needs to be replaced cannot be judged in time in prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: automobile brake structure suspension structure, including brake disc, brake disc edge is equipped with suspension frame body, brake cylinder is fixedly installed on suspension frame body, brake cylinder output end is fixedly installed with brake friction plate, detection mechanism is installed on suspension frame body, detection mechanism includes fixedly installed mounting shaft sleeve on suspension frame body, torsion spring is equipped in mounting shaft sleeve, movable shaft is rotatably installed on mounting shaft sleeve, detection pressure arm is fixedly installed on movable shaft, linkage shaft is fixedly installed between movable shaft, one end of movable shaft is connected with angle sensor, the other end of movable shaft is connected with driving mechanism.

[0009] Preferably, the driving mechanism comprises a protective shell fixedly installed on the side wall of the suspension frame body, a driving shaft rotatably installed in the protective shell, a speed reduction gear fixedly installed on the driving shaft, a motor clamping groove provided in the protective shell, a driving motor fixedly installed in the motor clamping groove, and a driving gear fixedly installed at the output end of the driving motor.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] 1. The torsion spring in the application provides necessary torsion for the movable shaft, and ensures that the detection pressure arm remains horizontal. When the driving shaft rotates, it will drive the movable shaft to rotate. The rotation of the movable shaft will further drive the detection pressure arm to rotate. If the brake friction plate is slightly worn, it will hinder the rotation path of the detection pressure arm, thereby limiting the rotation angle of the movable shaft. However, when the brake friction plate is severely worn, it will not effectively block the detection pressure arm, so that the movable shaft can rotate a larger angle. By monitoring the rotation angle of the movable shaft through the angle sensor, the user can easily judge whether the brake friction plate has been severely worn, so as to decide whether it needs to be replaced.

[0014] 2. The driving of the driving motor in the application can effectively drive the driving gear to rotate. When the driving gear starts to rotate, it will further transmit power, so that the speed reduction gear also starts to rotate. In the process of rotating, the speed reduction gear will continue to transmit power to the driving shaft, so that the driving shaft also starts to rotate. Subsequently, the rotation of the driving shaft will drive the movable shaft to rotate correspondingly. This series of rotation actions will eventually make the control detection mechanism automatically operate, so as to realize its detection function. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As shown in Figure 1 and Figure 2 The utility model provides a technical scheme of automobile brake structure suspension structure, including brake disc 1, brake disc 1 edge is equipped with suspension frame body 3, is fixedly installed with brake cylinder 2 on suspension frame body 3, and the output end of brake cylinder 2 is fixedly installed with brake friction plate 4, is installed with detection mechanism 5 on suspension frame body 3, movable shaft 503 other end is connected with drive mechanism 6, through the cooperation of detection mechanism 5 and drive mechanism 6, can judge whether brake friction plate 4 is seriously worn, and it is convenient for user to judge whether brake friction plate 4 needs to be replaced.

[0022] As shown in Figure 2 and Figure 3As shown, the detection mechanism 5 includes a mounting shaft sleeve 502 fixedly mounted on the suspension frame body 3, a torsion spring 507 arranged in the mounting shaft sleeve 502, a movable shaft 503 rotatably mounted on the mounting shaft sleeve 502, a detection pressure arm 505 fixedly mounted on the movable shaft 503, a linkage shaft 506 fixedly mounted between the movable shaft 503, an angle sensor 501 connected to one end of the movable shaft 503, an active port 504 formed in the mounting shaft sleeve 502, and the movable shaft 503 rotatably mounted on the mounting shaft sleeve 502 through the active port 504. The suspension frame body 3 is provided with a through hole, and the movable shaft 503 passes through the suspension frame body 3 through the through hole.

[0023] Specifically, through the operation of the driving motor 605, the driving gear 604 can be effectively driven to rotate. When the driving gear 604 starts to rotate, it further transmits power to make the reduction gear 602 start to rotate. During the rotation of the reduction gear 602, power is transmitted to the driving shaft 603, so that the driving shaft 603 also starts to rotate. With the rotation of the driving shaft 603, the movable shaft 503 also rotates. The rotation of the movable shaft 503 makes the detection mechanism 5 automatically operate.

[0024] As shown in Figure 2 and Figure 4 The driving mechanism 6 includes a protective shell 601 fixedly mounted on the side wall of the suspension frame body 3, a driving shaft 603 rotatably mounted in the protective shell 601, a reduction gear 602 fixedly mounted on the driving shaft 603, a motor clamping groove 606 arranged in the protective shell 601, a driving motor 605 fixedly mounted in the motor clamping groove 606, a driving gear 604 fixedly mounted at the output end of the driving motor 605, a shaft coupling arranged at the end of the driving shaft 603, and the movable shaft 503 fixedly mounted on the end of the driving shaft 603 through the shaft coupling.

[0025] Specifically, the torsion spring 507 provides the necessary torsion for the movable shaft 503, ensuring that the detection pressure arm 505 on the movable shaft 503 can remain in a horizontal position. When the driving shaft 603 starts to rotate, it drives the movable shaft 503 connected thereto to rotate. With the rotation of the movable shaft 503, the detection pressure arm 505 also rotates. If the brake friction plate 4 has slight wear, it will block the rotation path of the detection pressure arm 505, thereby limiting the rotation angle of the movable shaft 503. However, when the wear of the brake friction plate 4 becomes serious, it will no longer effectively block the rotation of the detection pressure arm 505, resulting in that the movable shaft 503 can rotate a larger angle. By accurately detecting the rotation angle of the movable shaft 503 through the angle sensor 501, we can determine the wear degree of the brake friction plate 4. This method provides convenience for users, enabling them to easily determine whether the brake friction plate 4 needs to be replaced.

[0026] Working principle: when using, brake cylinder 2 can drive brake friction plate 4 to move forward, so that brake friction plate 4 is in contact with the surface of brake disc 1, and the braking effect is realized. Driving motor 605 can drive driving gear 604 to rotate, driving gear 604 rotates and then drives speed reducer 602 to rotate, speed reducer 602 rotates and then drives driving shaft 603 to rotate, driving shaft 603 rotates and then drives movable shaft 503 to rotate, so that automatic control detection mechanism 5 operates. Torsion spring 507 provides torsion for movable shaft 503, so that detection pressure arm 505 on movable shaft 503 remains in a horizontal state, when driving shaft 603 rotates, it drives movable shaft 503 to rotate, movable shaft 503 rotates and then drives detection pressure arm 505 to rotate, slightly worn brake friction plate 4 will block the rotation track of detection pressure arm 505, limiting the rotation angle of movable shaft 503, and when brake friction plate 4 is seriously worn, it cannot block the rotation of detection pressure arm 505, so that movable shaft 503 can rotate to a larger angle, and the selected angle of movable shaft 503 detected by angle sensor 501 can be used to judge whether brake friction plate 4 is seriously worn, so that the user can judge whether brake friction plate 4 needs to be replaced.

Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
