Description

Technical Field

[0001] The present application relates to the technical field of vehicle adjustment, and in particular to a vehicle adjustment tool and an offline subassembly and adjustment system. Background Art

[0002] The four-wheel alignment instrument is a professional device specially used to detect and adjust the vehicle tire alignment parameters. It can help technicians measure and adjust the key parameters of the wheel's toe, toe-in, wheel width, wheel camber, kingpin caster angle, etc., to ensure the safety and stability of the vehicle's driving and reduce abnormal tire wear. The toe-in of the wheel refers to the distance difference between the front end and the rear end of the two front wheels when viewed from above the vehicle. Specifically, if the front ends of the two front wheels are closer to each other than the rear ends, that is, the front end distance is smaller than the rear end distance, this situation is called "positive toe-in"; conversely, if the front end distance is greater than the rear end distance, it is called "negative toe-in"; if the distance between the front end and the rear end is equal, that is, there is no distance difference, then it is "zero toe-in".

[0003] When adjusting the toe-in of the vehicle during four-wheel alignment, it is necessary to make adjustments in accordance with the fixed input parameters on the four-wheel aligner; specifically, during adjustment, the operator needs to adjust the adjustment nut on the steering tie rod at the bottom of the vehicle to adjust the length of the steering tie rod, thereby changing the toe-in angle, and then retighten the nut.

[0004] However, on the one hand, the four-wheel alignment operation is cumbersome, and each operator needs 6 minutes to adjust the wheel, which results in a long cycle time and affects the subsequent vehicle adjustment and delivery. On the other hand, the operator needs to adjust the nuts at the bottom of the vehicle, which is labor-intensive. Utility Model Content

The detailed descriptions and drawings of the following examples are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application. The present application can be implemented in many different forms and is not limited to the specific embodiments of the present application, but includes all technical solutions that fall within the scope of the claims.

[0030] The present application provides these embodiments to make the present application thorough and complete, and to fully express the scope of the present application to those skilled in the art.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] The toe of the wheels refers to the difference in distance between the front and rear ends of the two front wheels when viewed from above the vehicle. Specifically, if the front ends of the two front wheels are closer to each other than the rear ends, that is, the distance between the front ends is smaller than the distance between the rear ends, this is called "positive toe"; conversely, if the distance between the front ends is greater than the distance between the rear ends, it is called "negative toe"; if the distance between the front and rear ends is equal, that is, there is no distance difference, then it is "zero toe".

[0037] When adjusting the toe-in of the vehicle during four-wheel alignment, it is necessary to make adjustments in accordance with the fixed input parameters on the four-wheel aligner; specifically, during adjustment, the operator needs to adjust the adjustment nut on the steering tie rod at the bottom of the vehicle to adjust the length of the steering tie rod, thereby changing the toe-in angle, and then retighten the nut.

[0038] However, on the one hand, the four-wheel alignment operation is cumbersome, and each operator needs 6 minutes to adjust the wheel, which results in a long cycle time and affects the subsequent vehicle adjustment and delivery. On the other hand, the operator needs to adjust the nuts at the bottom of the vehicle, which is labor-intensive.

[0039] In order to solve the above technical problems, the present application provides a vehicle adjustment tool and a vehicle adjustment tool, so that the operator can use the tool to adjust the toe during assembly without adjusting it at the bottom of the vehicle, thereby reducing the working hours of four-wheel adjustment and reducing labor intensity.

[0040] Example 1

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a vehicle adjustment tool comprises a fixing part 1, a connecting part 2 and a positioning part 3; the fixing part 1 has a step-shaped clamping structure 11 for cooperating with the shoulder of the component to be adjusted; the connecting part 2 is in the shape of an elongated strip, and one end of the connecting part 2 in the length direction is connected to the fixing part 1; the positioning part 3 is connected to the other end of the connecting part 2 in the length direction, and there is a set distance between the positioning part 3 and the fixing part 1.

[0042] The fixing part 1 is a device having a step-shaped clamping structure 11 and can be installed on the shoulder of the component to be adjusted through the step-shaped clamping structure 11. The component to be adjusted is the steering tie rod 5, and the steering tie rod 5 is provided with an adjustment nut 4, which can adjust the length of the steering tie rod 5 and thus change the toe angle. Specifically, the step-shaped clamping structure 11 can be a step-shaped structure composed of two connecting parts connected at a set angle, or it can be an integrated structure, and a protrusion is provided at the bottom of the integrated structure to form a step-shaped clamping groove, and the step-shaped clamping groove cooperates with the shoulder of the steering tie rod 5, so as to fix the fixing part 1; as long as the step-shaped clamping structure 11 can be installed on the shoulder of the component to be adjusted, the shape of the step-shaped clamping structure 11 is not specifically limited.

[0043] The connecting portion 2 is a long strip structure used to connect the fixing portion 1 and the positioning portion 3. Specifically, the connecting portion 2 can be a rod-shaped structure or a plate-shaped structure, as long as the two ends of the connecting portion 2 can be connected to the fixing portion 1 and the positioning portion 3 respectively, so that the position of the positioning portion 3 can be positioned by the position of the fixing portion 1, and the specific structure and shape of the connecting portion 2 are not limited.

[0044] The positioning part 3 is a structure for positioning the specific position of the steering tie rod 5. Specifically, the positioning part 3 can be a slot-shaped structure, for example, the positioning part 3 can be a semicircular or square slot so as to be clamped on the steering tie rod 5; the positioning part 3 can also be a rod-shaped structure, which contacts the steering tie rod 5 to position the specific position of the steering tie rod 5, and the rod-shaped structure can also be arranged on the same side of the fixing part 1 but not in contact with the steering tie rod 5, as long as the adjusting nut 4 contacts the rod-shaped structure when it is adjusted to the specific position of the steering tie rod 5; similarly, the positioning part 3 can also be just the end of the connecting part 2, and the adjusting nut 4 contacts the end of the connecting part 2 when it is adjusted to the specific position of the steering tie rod 5. As long as the positioning part 3 can position the specific position of the steering tie rod 5, the specific structure of the positioning part 3 is not limited.

[0045] Compared with the prior art, the vehicle adjustment tooling provided in the present application fixes the tooling on the steering tie rod 5 through the fixing part 1, and connects the positioning part 3 and the fixing part 1 through the connecting part 2, and a set distance is set between the positioning part 3 and the fixing part 1, so that the positioning part 3 can locate the position to which the adjustment nut 4 needs to be adjusted, thereby allowing the operator to use the tooling to adjust the toe during assembly without adjusting at the bottom of the vehicle, thereby reducing the working hours for four-wheel adjustment and reducing labor intensity.

[0046] like Figure 2 As shown, in some modified embodiments of the present application, the fixing part 1 includes a first connecting member 111 and a second connecting member 112, and the sides of the first connecting member 111 and the second connecting member 112 are connected at a set angle to form a step-shaped clamping structure 11. Specifically, the first connecting member 111 and the second connecting member 112 can be a plate-like structure or a block-like structure. As long as the first connecting member 111 and the second connecting member 112 can be connected together to form a step-shaped clamping groove to match the shoulder of the steering tie rod 5, the specific structure of the first connecting member 111 and the second connecting member 112 is not limited. By connecting the sides of the first connecting member 111 and the second connecting member 112 at a set angle to form a step-shaped clamping structure 11, it can better match the shape of the shoulder, so that the fixing position of the fixing part 1 is more accurate, and then the positioning of the positioning part 3 is more accurate.

[0047] like Figure 1As shown, in some modified embodiments of the present application, the fixing portion 1 also includes a fixing rod 12, and the fixing rod 12 is connected to the set position of the second connecting member 112, and there is a set distance between the fixing rod 12 and the positioning portion 3. The fixing rod 12 is a structure used to connect with the second connecting member 112. Specifically, the fixing rod 12 can be a rod-shaped structure, or a block-shaped structure or a plate-shaped structure. As long as the fixing rod 12 can connect the second connecting member 112 and the connecting portion 2 together, the specific structure of the fixing portion 1 is not limited. By connecting the fixing rod 12 between the second connecting member 112 and the connecting portion 2, a certain gap can be provided between the step-shaped clamping structure 11 and the connecting portion 2, so as to avoid other structures on the steering tie rod 5 blocking the connecting portion 2, and facilitate the installation and practical use of the tooling.

[0048] In some modified embodiments of the present application, the second connecting member 112 is an arc-shaped plate, the first connecting member 111 is a semi-annular plate, and the first connecting member 111 and the second connecting member 112 together form a slot-shaped structure.

[0049] like Figure 2 and Figure 4 As shown, the second connecting member 112 is an arc-shaped plate, that is, a plate-like structure with an arc, so as to match the curved surface of the steering tie rod 5. Specifically, the second connecting member 112 can be a semi-cylindrical structure cut from a cross section, and the inner diameter of the semi-cylindrical structure is the same as or slightly smaller than the diameter of the steering tie rod 5 to be fixed, so that the second connecting member 112 and the steering tie rod 5 are interference-fitted, and then firmly fixed on the steering tie rod 5. The first connecting member 111 is a semi-annular plate structure that matches the shape of the shaft shoulder, so that the annular plate fits the shaft shoulder, so that the fixing position of the fixing portion 1 is more accurate, and then the positioning of the positioning portion 3 is more accurate.

[0050] In some modified embodiments of the present application, a third connecting member 113 is provided on one side of the first connecting member 111 away from the second connecting member 112. The third connecting member 113 is an arc-shaped plate. The opening direction of the third connecting member 113 is the same as the opening direction of the second connecting member 112 and the opening of the third connecting member 113 is smaller than the opening of the second connecting member 112. The third connecting member 113 and the second connecting member 112 can be semi-cylinders cut from a cross section. The inner diameter of the semi-cylinder is the same as or slightly smaller than the diameter of the steering tie rod 5 to be fixed, so that the second connecting member 112 and the steering tie rod 5 are interference-fitted, and then firmly fixed to the steering tie rod 5. By providing the third connecting member 113, the fixing part 1 can be more firmly fixed at the set position, thereby preventing the fixing part 1 from falling off during operation, thereby ensuring the accuracy of positioning.

[0051] In some modified embodiments of the present application, the positioning portion 3 has a positioning slot 31 , the positioning slot 31 and the positioning portion 3 are arranged on the same side of the connecting portion 2 , and a set distance is set between the positioning slot 31 and the fixing portion 1 .

[0052] The positioning slot 31 is a slot structure for fixing the steering tie rod 5 at a set position; specifically, the positioning slot 31 may be a slot with a semicircular cross section, or a slot with a semirectangular cross section. As long as the positioning slot 31 can clamp the positioning portion 3 at the set position of the steering tie rod 5, the specific structure of the positioning slot 31 is not limited. More specifically, the positioning slot 31 may be connected to the steering tie rod 5 through a positioning rod 32, or may be directly connected to the connecting portion 2 and the steering tie rod 5, and the specific connection method of the positioning slot 31 with the connecting portion 2 and the steering tie rod 5 is not limited.

[0053] In some modified embodiments of the present application, the positioning slot 31 is an arc-shaped plate, and a positioning plate 33 is provided on one side of the positioning slot 31 away from the connecting portion 2, and the positioning plate 33 is perpendicular to the extending direction of the connecting portion 2. The positioning slot 31 is an arc-shaped plate, that is, it can be a semi-cylinder cut from a cross section, and the inner diameter of the semi-cylinder is the same as or slightly smaller than the diameter of the steering tie rod 5 to be fixed, so that the positioning slot 31 and the steering tie rod 5 are interference-fitted, and then it is firmly fixed on the steering tie rod 5. The positioning plate 33 is a plate-like structure provided on one side of the positioning slot 31. Specifically, the shape of the positioning plate 33 can be adapted to the shape of the positioning slot 31, and can be a semi-annular plate, a semi-rectangular plate, or not adapted to the shape of the positioning slot 31, such as a rectangular plate. As long as the positioning plate 33 can be parallel to the end face of the adjusting nut 4 when the adjusting nut 4 is adjusted, the specific structure of the positioning plate 33 is not limited. A positioning plate 33 is provided on the side of the positioning slot 31 away from the connecting portion 2 , and the positioning plate 33 is perpendicular to the extending direction of the connecting portion 2 , so that the positioning plate 33 is parallel to the end face of the adjusting nut 4 , thereby improving the positioning accuracy of the adjusting nut 4 .

[0054] like Figure 1 and Figure 2 As shown, in some modified embodiments of the present application, a plurality of positioning slots 31 are arranged at intervals, and the positioning slots 31 are detachably connected to the connecting portion 2, and the opening direction of each positioning slot 31 is the same. By providing a plurality of positioning slots 31 arranged at intervals, and detachably connecting the plurality of positioning slots 31 to the connecting portion 2, positioning slots 31 at different positions can be selected according to different vehicle models, thereby adapting to a variety of different types of vehicle models, thereby increasing the adaptability range of the tooling and reducing the later investment cost.

[0055] In some modified embodiments of the present application, the positioning part 3 is slidably connected to the connecting part 2. Specifically, a slide groove can be provided on the connecting part 2, and the positioning part 3 is slidably connected in the slide groove; more specifically, a threaded hole can also be provided on the positioning part 3, and a plurality of threaded holes that match the threaded holes of the positioning part 3 can be arranged at intervals on the side wall of the slide groove to locate the position of the positioning part 3. The positioning part 3 can also be connected to the connecting part 2 by a lead screw, and the position of the positioning part 3 can be adjusted by the lead screw, so that the position of the positioning slot 31 can be adjusted according to different vehicle models, thereby adapting to a variety of different types of vehicle models, improving the adaptability range of the tooling, and reducing the later investment cost.
