Description

Technical Field

[0001] The utility model relates to the technical field of brake lever linkage, and particularly relates to a high-strength brake lever linkage mechanism with a self-lubricating bushing. Background Technique

[0002] A lever linkage mechanism is a mechanical device that uses the lever principle to achieve force transmission and amplification. It is commonly found in various mechanical equipment, such as cranes, shearing machines, brake pedals, and valve controls. The lever linkage principle is to change the magnitude and direction of force by changing the distances between the force point, resistance point, and fulcrum. Its balance condition is: the distance between the force application point and the fulcrum multiplied by the magnitude of the force is equal to the distance between the resistance point and the fulcrum multiplied by the magnitude of the resistance. According to different configurations of the lever, different operating effects can be achieved.

[0003] The application number is CN206436993U, which discloses a brake pedal including a pedal bracket, a pedal arm, and a pedal rotating shaft. One end of the pedal arm is fixed on the pedal rotating shaft and is hinged to the pedal bracket through the pedal rotating shaft. The other end of the pedal arm is provided with a pedal surface. The pedal arm includes a main pedal arm and a sub-pedal arm. One ends of the main and sub-pedal arms are respectively fixed at both ends of the pedal rotating shaft, enabling the main and sub-pedal arms to rotate synchronously around the axis of the pedal rotating shaft. The utility model can avoid interference between the pedal arm and the steering lower shaft without changing the position of the pedal bracket.

[0004] In the prior art, components such as a pedal bracket, a pedal arm, and a pedal rotating shaft are used to achieve linkage work. The pedal arm is hinged to the pedal bracket through the pedal rotating shaft, and the other end of the pedal arm is provided with a pedal surface, which rotates synchronously with the rotating shaft. While achieving braking, it avoids interference between the pedal arm and the lower shaft. During the braking process on the pedal surface, uneven forces on both sides are likely to damage the pedal arm, affecting the use of the brake pedal. At the same time, during the braking process, the components swing back and forth, and the sleeve and pin shaft are prone to wear, thus affecting the braking effect and service life. For this reason, we propose a high-strength brake lever linkage mechanism with a self-lubricating bushing to solve the above problems. Content of the Utility Model

[0005] The purpose of the present invention is to provide a high-strength brake lever linkage mechanism with a self-lubricating bushing to solve the problems that the existing brake lever linkage mechanism is prone to wear the pedal arm and the rotating shaft during use, and the pedal arm is prone to damage and break during emergency braking.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] This utility model relates to a high-strength brake lever linkage mechanism with a self-lubricating bushing, comprising a bracket structure. The bracket structure includes a mounting plate, with connecting plates on both sides of the bottom of the mounting plate. A base is mounted on the center of the side of the mounting plate. Through holes are opened on both sides of the outer surface of the mounting plate, and a movable mechanism is installed inside the through holes. The movable mechanism includes a rotating shaft, with springs sleeved on both sides of the rotating shaft. A transmission plate is mounted on one side of the rotating shaft, and the middle of the rotating shaft is connected to a support arm in a pedal structure. The pedal structure includes a support arm, with a mounting opening at the bottom of the support arm. Reinforcing ribs are installed on both sides of the support arm, and the bottom of the support arm is connected to the pedal. An anti-slip block is provided on the top of the pedal.

[0008] By installing a bushing between the rotating shaft and the fixed sleeve, and casting the bushing with a self-lubricating material, the friction between the support arm and the rotating shaft during braking is reduced, thereby extending the overall service life of the braking mechanism.

[0009] Furthermore, the mounting plate has symmetrical connecting plates on both sides of its bottom, and circular openings are provided on the outside of the connecting plates. Bases are fixedly installed on both sides of the bottom of the mounting plate, and bolts are adapted to be installed on the outside of the bases. Circular openings are provided on both sides of the outside of the mounting plate, and the openings are symmetrically distributed in relative positions. The inside of the openings is movably connected to the rotating shaft in the movable mechanism.

[0010] Furthermore, the rotating shaft is a circular shaft that extends to the outside of both sides of the mounting plate. Springs are movably sleeved on both sides of the rotating shaft. A transmission plate is sleeved and installed on the right side of the rotating shaft. A bushing is movably installed on the rear side of the transmission plate. A fixed sleeve plate is movably installed on the outside of the bushing. The middle part of the rotating shaft is movably connected to the support arm in the pedal structure.

[0011] Furthermore, the bushing is made of polymer graphite composite material, the top of the bushing is annular, and the inner diameter of the bushing is consistent with that of the rotating shaft and is movably fitted.

[0012] The reinforcing ribs are installed and movably mounted on both sides of the support arm via a ring plate and mounting base. This increases the strength and rigidity of the support arm during braking, enabling it to better withstand braking force, preventing deformation or breakage during use, and enhancing the protective function of the support arm.

[0013] Furthermore, a circular mounting opening is provided at the bottom of the support arm, a telescopic column is movably installed inside the mounting opening, a return spring is fixedly sleeved on the outside of the telescopic column, and a support base is fixedly provided at the bottom of the telescopic column.

[0014] Furthermore, reinforcing ribs are movably installed on both sides of the outer side of the support arm, and mounting bases are fixedly provided on both the upper and lower sides of the reinforcing ribs. The mounting bases have openings on the outside. A pedal is fixedly installed on the bottom surface of the support arm, and several sets of anti-slip blocks are evenly distributed on the top of the pedal. The anti-slip blocks are strip-shaped blocks.

[0015] Furthermore, an annular plate is fixedly sleeved on the outside of the reinforcing rib, the annular plate being consistent with the outer contour of the support arm, and the reinforcing rib being a strip-shaped column.

[0016] This utility model has the following beneficial effects:

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a high-strength brake lever linkage mechanism with a self-lubricating bushing, including a bracket structure 1. The bracket structure 1 includes a mounting plate 101, with connecting plates 102 on both sides of the bottom of the mounting plate 101. A base 103 is installed in the middle of the side of the mounting plate 101. Through holes 104 are opened on both sides of the outer side of the mounting plate 101, and a movable mechanism 2 is installed inside the through holes 104. The movable mechanism 2 includes a rotating shaft 201, with springs 202 sleeved on both sides of the rotating shaft 201. A transmission plate 203 is installed on one side of the rotating shaft 201, and the middle of the rotating shaft 201 is connected to the support arm 301 in the pedal structure 3. The pedal structure 3 includes a support arm 301, with an installation port at the bottom of the support arm 301. Reinforcing ribs 304 are installed on both sides of the support arm 301. The bottom of the support arm 301 is connected to the pedal 305, and the top of the pedal 305 is provided with an anti-slip block 306.

[0031] The mounting plate 101 has symmetrical connecting plates 102 on both sides of its bottom. The connecting plates 102 have circular openings on their outer sides. The mounting plate 101 has bases 103 fixedly installed on both sides of its bottom. The bases 103 have openings on their outer sides and are fitted with bolts. The mounting plate 101 has circular openings on both sides of its outer sides. The openings are symmetrically distributed in relative positions. The openings are movably connected to the rotating shaft 201 in the movable mechanism 2.

[0032] The rotating shaft 201 is a circular shaft that extends to the outside of both sides of the mounting plate 101. Springs 202 are movably sleeved on both sides of the rotating shaft 201. A transmission plate 203 is sleeved and installed on the right side of the rotating shaft 201. A bushing 204 is movably installed on the rear side of the transmission plate 203. A fixed sleeve plate 205 is movably installed on the outside of the bushing 204. The middle part of the rotating shaft 201 is movably connected to the support arm 301 in the pedal structure 3.

[0033] By setting a bushing 204 between the rotating shaft 201 and the fixed sleeve 205, the bushing 204 is made of self-lubricating material and is a polymer graphite composite material. The top of the bushing 204 is annular, and the inner diameter of the bushing 204 is consistent with that of the rotating shaft 201 and is movably fitted. During the braking process, the friction between the support arm 301 and the rotating shaft 201 is reduced, thereby extending the overall service life of the braking mechanism.

[0034] A circular mounting port is provided at the bottom of the support arm 301. A telescopic column is movably installed inside the mounting port. A return spring 302 is fixedly sleeved on the outside of the telescopic column. A support seat 303 is fixedly installed at the bottom of the telescopic column.

[0035] The support arm 301 has reinforcing ribs 304 movably installed on both sides of its exterior. The reinforcing ribs 304 have mounting bases fixed on both the upper and lower sides. The mounting bases have openings on their exterior. The support arm 301 has a pedal 305 fixedly installed on its bottom surface. Several sets of anti-slip blocks 306 are evenly distributed on the top of the pedal 305. The anti-slip blocks 306 are strip-shaped blocks. The anti-slip blocks 306 increase the friction between the foot and the pedal 305 when using the pedal 305 during braking, preventing the foot from slipping and improving the accuracy of braking.

[0036] Reinforcing ribs 304 are installed and movably mounted to both sides of the support arm 301 via an annular plate and mounting base. This increases the strength and rigidity of the support arm 301 during braking, enabling it to better withstand braking forces.

[0037] A ring plate is fixedly fitted on the outside of the reinforcing rib 304. The ring plate is consistent with the outer contour of the support arm 301. The reinforcing rib 304 is a strip column to prevent the support arm 301 from deforming or breaking during use and to enhance the protection of the support arm 301.

[0038] Working principle: In use, by installing the connecting plate 102 and the base 103 in the bracket structure 1 in their respective positions, when the pedal 305 at the bottom of the support arm 301 is pressed, the rotating shaft 201 in the movable mechanism 2 moves downward in conjunction with the spring 202, causing the telescopic column at the bottom of the support arm 301 to retract downward, thereby achieving a braking effect. By providing self-lubricating bushings 204 on both sides of the rotating shaft 201, the friction between the rotating shaft 201 and the support arm 301 during braking is reduced, strengthening the protection between the components. When the pedal 305 is released, the return spring 302 outside the telescopic column automatically resets, allowing the support arm 301 to return to its original position. During the braking process, the support arm 301 is provided with reinforcing ribs 304 on both sides to enhance rigidity and strength, ensuring that the force on both sides of the support arm 301 is even and not easily damaged, thereby extending the service life of the support arm 301.
