Description

Technical Field

[0001] This utility model relates to the field of brake adjustment equipment technology, and in particular to a portable brake adjustment arm positioning and adjustment device. Background Technology

[0002] As the core guarantee for safe driving, the performance and stability of the braking system are directly related to the life safety of drivers and passengers. As a key adjustment component in the braking system, the positioning accuracy and ease of adjustment of the brake adjustment arm play a decisive role in controlling the brake clearance, and thus affect the braking effect.

[0003] The existing method of adjusting the brake adjustment arm mainly relies on manual use of a wrench to repeatedly adjust the adjusting screw on the brake adjustment arm, and to observe whether the brake clearance meets the adjustment standard by pulling the brake adjustment arm. However, during the adjustment process, the control of the pulling force is entirely judged by the operator's experience, which may result in the brake clearance being too large or too small, directly threatening driving safety.

[0004] Therefore, a portable brake adjustment arm positioning and adjustment device has been developed that can assist operators in adjusting the brake adjustment arm through a pressure sensor, thereby improving the adjustment accuracy. Utility Model Content

[0005] To overcome the shortcomings of existing brake adjuster adjustment methods, where the control of tension relies entirely on the operator's experience, potentially leading to excessively large or small brake gaps that directly threaten driving safety, this invention provides a portable brake adjuster positioning and adjustment device that uses a pressure sensor to assist the operator in adjusting the brake adjuster, thereby improving adjustment accuracy.

[0006] The technical implementation scheme of this utility model is as follows: A portable brake adjusting arm positioning and adjustment device includes an electric push rod, a limit block, a limit rod, a spring, a connecting block, a wrench, and a brake adjusting arm. The electric push rod is connected to the left side of the limit block, and the limit rod is connected to the right side of the limit block. The connecting block is slidably connected to the limit rod, and a spring is connected between the connecting block and the limit rod. The wrench is connected to the lower side of the connecting block, and the brake adjusting arm is placed on the lower side of the limit block. The wrench is engaged with the adjusting screw on the brake adjusting arm.

[0007] Optionally, it also includes a connecting frame, a pressure sensor, a bidirectional lead screw, and clamps. The connecting frame is connected to the telescopic end of the electric actuator, the pressure sensor is connected to the connecting frame, the bidirectional lead screw is rotatably connected to the lower part of the connecting frame, and clamps are threadedly connected to both the front and rear parts of the bidirectional lead screw. The clamps are slidably connected to the connecting frame and are in contact with the brake adjusting arm.

[0008] Optionally, all clamping blocks are U-shaped structures.

[0009] Optionally, it also includes a rotating fixing plate, which is connected to the front side of the lead screw.

[0010] Optionally, the rotating fixed plate is provided with a rotating plate to facilitate rotation.

[0011] Optionally, it also includes a pull rod, with the pull rod connected to the upper side of the connecting frame.

[0012] This utility model has the following advantages: By activating the electric actuator, the telescopic tube of the electric actuator retracts, causing the clamping block to pull the brake adjusting arm. The pulling force can be controlled by a pressure sensor. By observing whether the brake clearance of the brake adjusting arm meets the adjustment requirements under the specified pulling force, the operator can be assisted in adjusting the brake adjusting arm through the pressure sensor, thereby improving the adjustment accuracy.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0019] A portable brake adjustment arm positioning and adjustment device, such as Figures 1-4 As shown, it includes an electric actuator 1, a limit block 2, a limit rod 3, a spring 4, a connecting block 5, a wrench 6, a brake adjusting arm 7, a connecting frame 8, a pressure sensor 9, a pull rod 10, a two-way lead screw 11, a rotating fixing plate 12, and a clamping block 13.

[0020] A push rod 1 is connected to the left side of the limiting block 2, and a limiting rod 3 is connected to the right side of the limiting block 2. A connecting block 5 is slidably connected to the limiting rod 3, and a spring 4 is connected between the connecting block 5 and the limiting rod 3. A wrench 6 is connected to the lower side of the connecting block 5, and a brake adjusting arm 7 is placed on the lower side of the limiting block 2.

[0021] The wrench 6 engages with the adjusting screw on the brake adjusting arm 7. A connecting frame 8 is connected to the telescopic end of the electric actuator 1. A pressure sensor 9 is connected to the connecting frame 8, and a pull rod 10 is connected to the upper side of the connecting frame 8. A bidirectional lead screw 11 is rotatably connected to the lower part of the connecting frame 8, and a rotating fixing plate 12 is connected to the front side of the lead screw. The rotating fixing plate 12 is equipped with a rotating plate for easy rotation. Both the front and rear parts of the bidirectional lead screw 11 are threadedly connected to clamping blocks 13. The clamping blocks 13 are slidably connected to the connecting frame 8 and are in contact with the brake adjusting arm 7. The clamping blocks 13 are all U-shaped structures.

[0022] When using this utility model, first move the device to the installation position of the brake adjusting arm 7, then rotate the fixing plate 12 to make the bidirectional screw 11 rotate, and the clamping block 13 opens under the action of the thread. After the clamping block 13 is put on the brake adjusting arm 7, rotate the fixing plate 12 in the opposite direction to make the bidirectional screw 11 rotate in the opposite direction, and drive the clamping blocks 13 to come closer to each other and clamp on the brake adjusting arm 7 to fix the device. At the same time, the wrench 6 will slide downward on the limit rod 3 under the elastic action of the spring 4, so that the wrench 6 will be engaged on the adjusting bolt of the brake adjusting arm 7. Then, the wrench 6 will be rotated to adjust the adjusting bolt of the brake adjusting arm 7. After one adjustment, the electric push rod 1 can be activated to retract the telescopic tube of the electric push rod 1, so that the clamp 13 pulls the brake adjusting arm 7. The pulling force can be controlled by the pressure sensor 9. By observing whether the brake clearance of the brake adjusting arm 7 meets the adjustment requirements under the specified pulling force, the lever 10 can be used by the operator to stabilize it and improve the stability when pulling. After repeated adjustments, the brake clearance is adjusted to the position that meets the requirements, thereby enabling the operator to adjust the brake adjusting arm 7 with the assistance of the pressure sensor 9 and improving the adjustment accuracy.
