Description

Technical Field

[0001] The present invention relates to the technical field of vehicle debugging, and in particular to an auxiliary device for handbrake adjustment and handbrake adjustment equipment. Background Art

[0002] After the various parts of the handbrake system are assembled in the automobile manufacturer's final assembly workshop, an initial adjustment must be made to the entire handbrake system using the adjusting nut on the handbrake mechanism. The quality of the car's handbrake adjustment directly affects the car's fuel consumption and performance.

[0003] If the handbrake cable is adjusted too tight, the brake shoes on the rear brake caliper will grip the brake disc, causing brake shoe wear, increased fuel consumption, and in severe cases, rear wheel lock. If the handbrake cable is adjusted too loose, the vehicle will not have sufficient braking force when parked on a slope, causing the vehicle to roll down the slope, which can cause a safety accident. The purpose of initial handbrake adjustment is to optimize the handbrake cable by adjusting the nut. This ensures that the parking brake requirements are met while preventing the brake shoes from gripping the brake disc and causing excessive wheel retarding force.

[0004] In the prior art, the hand brake system is generally adjusted manually by an operator, which has the problems of long adjustment time, complicated operation process and easy deviation. Summary of the Invention

[0016] In some optional solutions, an outer sleeve is provided on the mounting frame, the outer sleeve is sleeved on the outside of the rotating shaft, and the outer sleeve is provided with an opening for the operating handle to move.

[0017] In some optional schemes, a snap-in groove is provided on the side of the rotating shaft close to the angle measuring mechanism, and a measuring rod is provided on the angle measuring mechanism. The measuring rod extends into the snap-in groove, so that when the rotating shaft rotates, the measuring rod is driven to rotate through the snap-in groove.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The following is a further detailed description of an auxiliary device for handbrake adjustment and a handbrake adjustment device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0035] like Figure 3 and Figure 4 As shown, on the one hand, an auxiliary device for adjusting a handbrake is provided, comprising:

[0036] A mounting bracket 1, which is used to be connected to a brake disc 2;

[0037] A linkage mechanism 3 is provided on the mounting frame 1 and is used to be connected to the pull rod of the brake caliper 4. The linkage mechanism 3 rotates with the movement of the pull rod of the brake caliper 4.

[0038] The angle measuring mechanism 5 is used to detect the rotation angle of the linkage mechanism 3 .

[0039] When using the auxiliary device for handbrake adjustment, the mounting frame 1 is connected to the brake disc 2, and the linkage mechanism 3 provided on the mounting frame 1 is connected to the pull rod of the brake caliper 4, so that the linkage mechanism 3 rotates with the movement of the pull rod of the brake caliper 4. The angle measuring mechanism 5 is used to detect the angle of rotation of the linkage mechanism 3. When the rotation angle of the linkage mechanism 3 detected by the angle measuring mechanism 5 reaches the set value, that is, when the linkage mechanism 3 rotates to the set angle, the pull rod is in the optimal state and the handbrake adjustment is complete. Using the auxiliary device for handbrake adjustment to adjust the handbrake shortens the adjustment time, improves the adjustment efficiency, and produces accurate adjustment results, thus solving the problems of long adjustment time, complicated operation process, and easy deviation in the prior art.

[0040] In this example, angle measurement mechanism 5 can determine the rotation angle of linkage mechanism 3. The angle determined when the pull rod is in its optimal state can be tested and is thus the set angle. Angle measurement mechanism 5 is an angle sensor with a minimum measurement angle of 360° / 8192 = 0.0439°, which meets the required adjustment accuracy.

[0041] like Figure 1 and Figure 2 As shown, in some optional embodiments, the linkage mechanism 3 includes:

[0042] a claw 31 for connecting to a pull rod of the brake caliper 4;

[0043] One end of the rotating shaft 32 is connected to the claw 31 , and the other end is connected to the angle measuring mechanism 5 . The rotating shaft 32 is rotatably connected to the mounting bracket 1 .

[0044] In this embodiment, the specific structure of the linkage mechanism 3 is described. The linkage mechanism 3 includes a claw 31 and a rotating shaft 32, wherein the claw 31 is connected to the pull rod of the brake caliper 4, one end of the rotating shaft 32 is connected to the claw 31, and the other end is connected to the angle measuring mechanism 5, and the rotating shaft 32 is rotatably connected to the mounting frame 1. When the pull rod of the brake caliper 4 moves, the claw 31 rotates, driving the rotating shaft 32 to rotate, so that the angle measuring mechanism 5 obtains the rotation angle. The structure is simple and easy to manufacture.

[0045] In this example, the claw 31 is mounted on the rotating shaft 32 by a fixing screw. The claw 31 is positioned on the pull rod of the brake caliper 4 according to the spring device in the rotating shaft 32 and has a certain pre-pressure on the pull rod of the brake caliper 4.

[0046] like Figure 1-Figure 4 As shown, in some optional embodiments, the linkage mechanism 3 further includes an operating handle 33 , which is connected to the rotating shaft 32 and is used to adjust the position of the claw 31 .

[0047] In this embodiment, the linkage mechanism 3 also includes an operating handle 33, which is connected to the rotating shaft 32 and is used to adjust the position of the claw 31. When installing the auxiliary device for handbrake adjustment, the operating handle 33 is pulled to a vertical and horizontal state so that the claw 31 does not interfere with the brake caliper 4, making it convenient to place the claw 31 into the inner side of the brake caliper 4. When using the auxiliary device for handbrake adjustment, the operating handle 33 is pulled clockwise to connect the claw 31 to the pull rod of the brake caliper 4, which facilitates the adjustment process of the handbrake. After the adjustment is completed, the operating handle 33 is reset to a vertical and horizontal state, and the auxiliary device for handbrake adjustment is taken out. Using the operating handle 33 can facilitate the installation or disassembly of the auxiliary device for handbrake adjustment, thereby improving the efficiency of the handbrake adjustment process. The operating handle 33 can also facilitate the operator to pick up the auxiliary device for handbrake adjustment to facilitate the removal or installation of the auxiliary device for handbrake adjustment.

[0048] In this example, the mounting frame 1 is located on the outside of the brake disc 2, and the mounting frame 1 extends toward the side where the brake caliper 4 is located. The linkage mechanism 3 is located at one end of the mounting frame 1 extending out of the plane where the brake caliper 4 is located, and extends toward the inside of the brake disc 2. The linkage mechanism 3 is located on the side of the brake caliper 4 away from the brake disc 2. The auxiliary device for handbrake adjustment is designed according to the shape of the brake caliper 4 and the brake disc 2 to ensure that the auxiliary device for handbrake adjustment fits well with the brake caliper 4 and the brake disc 2, avoiding measurement deviations due to factors such as vehicle body shaking and vibration.

[0049] like Figure 2 As shown, in some optional embodiments, the mounting frame 1 is provided with an outer sleeve 34 , which is sleeved on the outside of the rotating shaft 32 , and the outer sleeve 34 is provided with an opening for the operating handle 33 to move.

[0050] In this embodiment, an outer sleeve 34 is provided on the mounting frame 1, and the outer sleeve 34 is sleeved on the outside of the rotating shaft 32. The outer sleeve 34 is provided with an opening for moving the operating handle 33. The rotating shaft 32 can rotate in the outer sleeve 34. Sleeving the outer sleeve 34 on the outside of the rotating shaft 32 can provide a certain protection for the rotating shaft 32, preventing debris in the external environment from affecting the rotation of the rotating shaft 32, resulting in inaccurate measurement results.

[0051] like Figure 2 As shown, in some optional embodiments, a snap-in groove 321 is provided on the side of the rotating shaft 32 close to the angle measuring mechanism 5, and a measuring rod 51 is provided on the angle measuring mechanism 5. The measuring rod 51 extends into the snap-in groove 321, so that when the rotating shaft 32 rotates, the measuring rod 51 is driven to rotate through the snap-in groove 321.

[0052] In this embodiment, a snap-in groove 321 is provided on the side of the rotating shaft 32 close to the angle measuring mechanism 5, and a measuring rod 51 is provided on the angle measuring mechanism 5. The angle measuring mechanism 5 reads the angle according to the rotation angle of the measuring rod 51. The measuring rod 51 is inserted into the snap-in groove 321 so that the measuring rod 51 rotates synchronously with the rotation of the snap-in groove 321. The angle measuring mechanism 5 measures the rotation angle of the rotating shaft 32 in the above manner, making the structure simpler and more reasonable and more reliable.

[0053] like Figure 1 and Figure 2 As shown, in some optional embodiments, the mounting bracket 1 includes:

[0054] The mounting plate 11 includes a mounting portion and a connecting portion, wherein the mounting portion is used to connect the brake disc 2;

[0055] The connecting plate 12 is connected to the connecting portion. A through hole is provided on the connecting plate 12 , and the through hole is used to connect the linkage mechanism 3 .

[0056] In this embodiment, the specific structure of the mounting frame 1 is specifically described. The mounting frame 1 includes a mounting plate 11 and a connecting plate 12, wherein the mounting plate 11 includes a mounting portion and a connecting portion. The mounting portion is used to connect the brake disc 2 and is arranged on the outside of the brake disc 2. The connecting plate 12 is connected to the connecting portion. A through hole is provided on the connecting plate 12, and the through hole is used to connect the linkage mechanism 3. The connecting plate 12 is arranged on the side of the mounting plate 11 away from the brake disc 2, which simplifies the structure and facilitates manufacturing and installation.

[0057] In this example, the angle measuring mechanism 5 is located on a side of the connecting plate 12 away from the linkage mechanism 3 , and the through hole, the rotating shaft 32 and the angle measuring mechanism 5 are coaxially arranged.

[0058] like Figure 1 As shown, in some optional embodiments, pressure beads 6 are provided on both the upper and lower sides of the connecting portion, and the pressure beads 6 press the brake caliper 4.

[0059] In this embodiment, pressure beads 6 are provided on both the upper and lower sides of the connection part of the mounting plate 11. The pressure beads 6 press the brake caliper 4 to facilitate the positioning of the auxiliary device for handbrake adjustment, thereby preventing the auxiliary device for handbrake adjustment from being difficult to position during measurement, thereby affecting the efficiency of the adjustment rod.

[0060] In this example, a caliper groove is provided on the brake caliper 4, and the pressure ball 6 is squeezed and embedded in the caliper groove, so that the positioning effect of the auxiliary device for handbrake adjustment is better, more stable and reliable.

[0061] like Figure 1 As shown, in some optional embodiments, a plurality of embedded magnets 112 are provided on the mounting plate 11 , and the mounting plate 11 is connected to the brake disc 2 via the plurality of embedded magnets 112 .

[0062] In this embodiment, a plurality of embedded magnets 112 are provided on the mounting plate 11. The mounting plate 11 is connected to the brake disc 2 through the plurality of embedded magnets 112 and is adsorbed on the brake disc by magnetic force, thereby ensuring the stability of the tooling and not causing movement deviation when measuring the pull rod rotation distance of the brake caliper 4, thereby meeting the automatic adjustment accuracy requirements of the equipment and preventing other fixed connection methods from damaging the brake disc 2.

[0063] In this example, a mounting hole 111 is provided in the middle of the mounting portion. The mounting hole 111 is used to avoid the structure of the brake disc 2 and can facilitate the positioning of the mounting frame 1 on the brake disc 2. A plurality of embedded magnets 112 are arranged around the mounting hole 111.

[0064] like Figure 1 As shown, in some optional embodiments, a handle 113 is provided on the side of the mounting portion away from the brake disc 2 .

[0065] In this embodiment, a handle 113 is provided on the side of the mounting portion away from the brake disc 2 to facilitate the operator in removing or installing the auxiliary device for adjusting the handbrake.

[0066] like Figure 3 and Figure 4 As shown, on the other hand, a handbrake adjustment device is provided, which includes the above-mentioned auxiliary device for handbrake adjustment.

[0067] When using the handbrake adjustment device, the mounting bracket 1 of the auxiliary device for handbrake adjustment is connected to the brake disc 2, and the linkage mechanism 3 provided on the mounting bracket 1 is connected to the pull rod of the brake caliper 4, so that the linkage mechanism 3 rotates with the movement of the pull rod of the brake caliper 4. The angle measuring mechanism 5 is used to detect the rotation angle of the linkage mechanism 3. When the rotation angle of the linkage mechanism 3 detected by the angle measuring mechanism 5 reaches the set value, that is, when the linkage mechanism 3 rotates to the set angle, the pull rod is in the optimal state and the handbrake adjustment is complete. Using the auxiliary device for handbrake adjustment to adjust the handbrake shortens the adjustment time, improves the adjustment efficiency, and produces accurate adjustment results, thus solving the problems of long adjustment time, complicated operation process, and easy deviation in the prior art.

[0068] In this example, the handbrake adjustment equipment includes a servo tightening machine and an auxiliary device for handbrake adjustment. The handbrake adjustment is to tighten the adjustment nut through the servo tightening machine to make the handbrake brake rod in an optimal state, so that the pull rod of the brake caliper 4 can meet the vehicle parking brake requirements, and at the same time, the brake shoe will not clamp the brake disc to cause excessive wheel braking force. The auxiliary device for handbrake adjustment connects the linkage mechanism 3 set on the mounting frame 1 to the pull rod of the brake caliper 4, so that the linkage mechanism 3 rotates with the movement of the pull rod of the brake caliper 4. The angle measuring mechanism 5 is used to detect the rotation angle of the linkage mechanism 3. When the linkage mechanism 3 rotates to the set angle, the handbrake brake rod is in the optimal state, the angle measuring mechanism 5 reaches the set value, and sends a stop signal to the servo tightening machine, thereby achieving the purpose of adjusting the handbrake brake of the vehicle model.

[0069] When using the handbrake adjustment equipment, take the auxiliary device for handbrake adjustment from the storage box, position it at the brake disc 2 and the brake caliper 4, operate the operating handle 33 to press the claw 31 onto the pull rod of the brake caliper 4; press the start button of the servo tightening machine, tighten the adjusting nut until the angle measuring mechanism 5 detects the movement of the pull rod of the brake caliper 4 and drives the linkage mechanism 3 to rotate to the set angle, transmits a stop signal to the servo tightening machine, and the servo tightening machine automatically shuts down, and the adjustment is completed; reset the operating handle 33 so that the claw 31 can pass through the brake caliper 4 smoothly, and then remove the auxiliary device for handbrake adjustment from the rear brake disc 2 and put it back into the storage box.

[0070] In summary, when using this auxiliary device for handbrake adjustment, the mounting bracket 1 is connected to the brake disc 2, and the linkage mechanism 3 disposed on the mounting bracket 1 is connected to the pull rod of the brake caliper 4, so that the linkage mechanism 3 rotates with the movement of the pull rod of the brake caliper 4. The angle measuring mechanism 5 is used to detect the rotation angle of the linkage mechanism 3. When the rotation angle of the linkage mechanism 3 detected by the angle measuring mechanism 5 reaches a set value, that is, when the linkage mechanism 3 rotates to the set angle, the pull rod is in an optimal state and the handbrake adjustment is complete. Using this auxiliary device for handbrake adjustment to adjust the handbrake shortens adjustment time, improves adjustment efficiency, and produces accurate adjustment results, thereby resolving the problems of long adjustment time, complex operation, and proneness to deviation in the prior art.

[0071] In the prior art, manual adjustment of the handbrake has the following problems: 1. Long manual operation time: The operation time is about one and a half minutes, the labor cost is high, and the efficiency of adjustment is reduced; 2. The manual adjustment operation is complicated: many tools and tooling are used, and there are many operation steps. If the adjustment is not in place in one time, repeated adjustments are required; 3. Poor ergonomics of manual operation: The vehicle body is at a height of 500, and the operator needs to get on and off the vehicle at least once to complete the entire adjustment process, which has poor operability. In addition, the operator needs to sit in the vehicle and bend over to operate during the adjustment process, and the operating posture is poor, which is not conducive to the operator's health; 4. The labor intensity of manual adjustment is high: During the entire adjustment process, the operator needs to repeatedly pull up and release the brake handbrake, which can easily cause arm muscle fatigue.

[0072] In order to solve the above problems, the present application provides an auxiliary device for handbrake adjustment and a handbrake adjustment device. The use of the auxiliary device and handbrake adjustment device for handbrake adjustment meets the technical requirements of automatic adjustment of the equipment. Compared with the manual handbrake adjustment method, the single-vehicle operation time is saved by one minute, the time required for adjustment is reduced, production efficiency is improved, lean production is achieved, and adjustment deviations caused by human factors are eliminated. The qualified rate of one adjustment can be increased from 70% to 99.9%, thereby improving the quality of the entire vehicle. At the same time, the use of the auxiliary device and handbrake adjustment device for handbrake adjustment solves the problems of complex manual adjustment operations, poor ergonomics and high labor intensity for operators, thereby achieving the goal of people-oriented and intelligent manufacturing.
