Description

Technical Field

[0001] This utility model belongs to the field of automotive transmission bench testing technology, specifically a universal fixed bracket for a multi-directionally adjustable shift lever used in MT testing. Background Technology

[0002] With the diversification of automotive shifting systems, MT testing faces the challenge of diverse installation interfaces. The mounting holes for shift levers on different vehicle models exhibit non-uniform distribution (e.g., non-standard sizes such as spacing of 38mm or 57mm), and the mounting base may have casting curvature or welding deformation. Traditional mounting brackets using a single slide rail or perforated plate present the following problems:

[0003] 1. Insufficient hole position compatibility; it only adapts to specific hole positions and cannot be compatible with non-standard mounting holes.

[0004] 2. The adjustment function is limited and cannot achieve coordinated adjustment of height and angle;

[0005] 3. Poor adaptability to mounting surfaces, making it difficult to match non-planar mounting bases.

[0006] The following problems may arise during the experiment:

[0007] 1. High testing costs: Customized brackets are required for each vehicle model, increasing tooling costs;

[0008] 2. Inefficient: Each adjustment takes 25 minutes, and repeated disassembly and reassembly are required due to misaligned holes;

[0009] 3. Risk of data distortion: Poor fit of the mounting surface may cause shift force detection error of ±8N (exceeding the ±5N allowed by ISO 22743). Summary of the Invention

[0010] To address the problems existing in the background technology, this utility model provides a universal fixed bracket for a multi-directional adjustable shift handle used in MT testing.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: a universal fixed bracket for a multi-directional adjustable shift handle for MT testing, comprising a transition plate, a fixing mechanism, two adjusting mechanisms, two through holes one, two through holes two, and four oblong holes one;

[0012] The transition plate is provided with two symmetrically arranged through holes one, two symmetrically arranged through holes two, and four waist-shaped holes one. The two adjustment mechanisms are respectively installed on the two sides of the transition plate. Each adjustment mechanism is connected to the corresponding through hole one and through hole two by a detachable connection. The longitudinal rails in the two adjustment mechanisms are symmetrically arranged, and the rotating disks in the two adjustment mechanisms are staggered front and back. The four waist-shaped holes one are detachably connected to the fixing mechanism.

[0013] Each of the aforementioned adjustment mechanisms includes a transverse track, a longitudinal track, and a rotating disk;

[0014] The transverse track has a waist-shaped hole 2 along its length. The longitudinal track has a rectangular frame structure and waist-shaped holes 3 on both sides. The two waist-shaped holes 3 are used in conjunction with the corresponding waist-shaped holes 2. The lower end of the longitudinal track is fixedly connected to the rotating disk. The rotating disk has a through hole 3 that matches the through hole 1. The through hole 3 and the corresponding through hole 1 are detachably connected. The rotating disk has an arc track that matches the through hole 2. The arc track and the corresponding through hole 2 are detachably connected.

[0015] The fixing mechanism includes a vertical plate, ribs, and a base plate;

[0016] The upright plate is provided with two rows of threaded holes. The four waist-shaped holes on the transition plate are respectively detachably connected to the corresponding threaded holes by bolts. The lower end of the upright plate is fixedly connected to the base plate. The base plate is fixedly connected to the rib plate. The rib plate is fixedly connected to the upright plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. High adaptability and flexibility: This solution achieves adaptation of non-uniformly distributed holes through the combination of horizontal and vertical rails, with a continuously adjustable spacing range of 15-60mm. It can be compatible with the mounting holes of gear shift levers of various car models, greatly improving the versatility and flexibility of the bracket.

[0019] 2. Coordinated adjustment of angle and height: The tilt angle of the gear shift handle can be infinitely adjusted within the range of 0°-90° by the combination of the rotating disk and the transition plate, and the angle is locked by the bolts and nuts on the arc track and through hole 2; at the same time, by adjusting the connection position of the transition plate and the vertical plate, the height of the gear shift handle can be adjusted synchronously within a range of ±20mm, which meets the height adjustment requirements of different vehicle models and test needs.

[0020] 3. Improved testing efficiency and reduced costs: The components of this solution are highly interchangeable, supporting rapid assembly and disassembly, and adaptable to the testing needs of different vehicle models. This not only simplifies the assembly process and reduces pre-test work, but also avoids the high cost of customizing special brackets for a single vehicle model, thereby improving testing efficiency and reducing overall costs.

[0021] 4. Enhanced Stability and Reliability: A silicone rubber gasket is added between the base plate and the test platform. This gasket can be compressed and deformed to compensate for local unevenness in the mounting surface, ensuring a good fit and improving the stability and reliability of the mounting bracket. This helps reduce shifting force detection errors caused by poor mounting surface fit, thus improving the accuracy of test data.

[0022] 5. Simulate actual usage conditions: Through the adjustable bracket, this solution can simulate the position of the gear shift lever installed on the vehicle in actual use, thereby improving the reference value of the test; this is of great significance for evaluating the performance of the gear shift lever in a real vehicle environment.

[0023] 6. Easy to manufacture and maintain: The standardized design of parts means that this solution only includes a few common profiles (such as transverse slide rails, longitudinal slide rails, rotary disks, etc.), resulting in low mold costs and simple manufacturing; at the same time, it also facilitates subsequent maintenance and upgrades, reducing maintenance costs and time costs.

[0024] In summary, this invention demonstrates significant advantages in improving adaptability, flexibility, testing efficiency, stability, reliability, and cost reduction, providing an efficient and reliable solution for fixing and adjusting the shift lever in MT testing.

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

[0030] This embodiment describes a universal fixed bracket for a multi-directional adjustable shift handle used in MT testing, including a transition plate 4, a fixing mechanism, two adjusting mechanisms, two through holes 5, two through holes 6, and four oblong holes 12.

[0031] The transition plate 4 is provided with two symmetrically arranged through holes 5 (for connecting the adjustment mechanism), two symmetrically arranged through holes 6 (located below the first through hole for angle locking), and four oblong holes 12 (located below the second through hole for connecting the fixing mechanism). The two adjustment mechanisms are respectively installed on the two sides of the transition plate 4. Each adjustment mechanism is connected to the corresponding through hole 5 and through hole 6 by a detachable connection (such as M8 bolts and nuts). The longitudinal rails 2 in the two adjustment mechanisms are symmetrically arranged, and the rotating disks 3 in the two adjustment mechanisms are staggered front and back. The four oblong holes 12 are detachably connected to the fixing mechanism (such as by M6 bolts and nuts).

[0032] Each of the aforementioned adjustment mechanisms includes a transverse track 1, a longitudinal track 2, and a rotating disk 3;

[0033] The transverse track 1 (which can be made of high-strength aluminum alloy) has a waist-shaped hole 2 along its length. The longitudinal track 2 is a rectangular frame structure (which can be made of cold-rolled steel plate with a thickness of 5mm) and has waist-shaped holes 3 on both sides. The two waist-shaped holes 3 are used to cooperate with the corresponding waist-shaped holes 2 (which can be fixed by M8 bolts and nuts). The lower end of the longitudinal track 2 is welded and fixedly connected to the rotating disk 3. The rotating disk 3 (which is a quarter-circle shape, made of ductile iron with a thickness of 12mm, an arc radius of 80mm, and a central angle of 90°) has a through hole 3 that matches the through hole 5. The through hole 3 and the corresponding through hole 5 (e.g., through M8 bolts and nuts) can be detachably connected. The rotating disk 3 has an arc track 7 that cooperates with the through hole 2 6. The arc track 7 and the corresponding through hole 2 6 (e.g., through M6 bolts and nuts) can be detachably connected.

[0034] The fixing mechanism includes a vertical plate 8, a rib plate 10, and a base plate 11;

[0035] The upright plate 8 is provided with two rows of threaded holes 9. The four waist-shaped holes 12 on the transition plate 4 are respectively detachably connected to the corresponding threaded holes 9 by bolts (such as M6 bolts). The lower end of the upright plate 8 is fixedly connected to the base plate 11. The base plate 11 is fixedly connected to the rib plate 10. The rib plate 10 is fixedly connected to the upright plate 8.

[0036] Before use, first fix the base plate 11 firmly to the experimental table with bolts (such as M10 bolts) or other fixing methods to ensure the stability of the entire bracket. Add a silicone rubber gasket (such as a silicone rubber gasket with a thickness of 3mm and a maximum compressible deformation of 0.5mm) between the base plate 11 and the experimental table. The gasket can be compressed and deformed to compensate for local unevenness of the mounting surface, ensure good fit of the mounting surface, and improve the stability and reliability of the fixed bracket.

[0037] Preliminary connection of the shift lever: The transverse rails 1 on the two adjustment mechanisms are fixed to the MT shift lever to be tested by bolts and nuts. The four mounting holes of the existing MT shift lever correspond to the two waist-shaped holes 2 of the transverse rails 1 and are fixed by bolts and nuts to achieve the preliminary connection between the shift lever and the bracket.

[0038] Combination of horizontal and vertical tracks: Then place the two horizontal tracks 1 on the corresponding vertical tracks 2, so that the waist-shaped hole 2 of each horizontal track 1 corresponds to the waist-shaped hole 3 on the corresponding vertical track 2, and then fix it with bolts and nuts. The installation position of each set of bolts and nuts can be adjusted independently to adapt to the hole distribution of different handles. Through the combination of horizontal and vertical tracks, the adaptation of non-uniformly distributed hole positions can be achieved, and the spacing range is continuously adjustable from 15-60mm.

[0039] Angle Adjustment: The rotating disk 3 is a quarter-circle shape. When it is necessary to fix the shift handle with different tilt angles, first loosen the bolts and nuts between the through hole 1 5 and the through hole 3, as well as the bolts and nuts between the arc track 7 and the corresponding through hole 2 6, so that the rotating disk 3 rotates around the corresponding through hole 1 5 as the axis, and the arc track 7 slides along the rod of the corresponding bolt until the desired tilt angle is reached. After the shift handles with different tilt angles are adapted, tighten the corresponding bolts and nuts respectively to fix the position of the rotating disk 3, so as to realize the stepless adjustment of the handle tilt angle from 0° to 90°, and achieve the angle locking through the bolts and nuts on the arc track 7 and the through hole 2 6.

[0040] Height Adjustment: The four oblong holes 12 on the transition plate 4 are detachably connected to the threaded holes 9 on the vertical plate 8 in the fixing mechanism by bolts. Unscrew the bolts connecting the transition plate 4 and the vertical plate 8. As needed, by replacing different threaded holes 9 or adjusting the fixing position of the four oblong holes 12, the height of the gear shift lever can be adjusted synchronously. After adjustment, tighten all bolts to ensure that the height and angle parameters are fixed together to meet the height adjustment requirements of different vehicle models and test requirements. The adjustment range is ±20mm.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
