Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an auxiliary tool for installing a leaf spring. Background Art

[0002] The leaf spring on the car is the most widely used elastic element in the car suspension. It is mainly composed of several alloy spring leaves of equal width and unequal length (equal or unequal thickness), forming an elastic beam with roughly equal strength.

[0003] The main function of the leaf spring is to connect the frame and the axle in the form of suspension. It is exposed between the frame and the axle, bears the load impact of the wheel on the frame, reduces the violent vibration of the vehicle body, and maintains the stability of the vehicle and its adaptability to different road conditions. One end of the leaf spring is hinged to the frame, and the frame can transmit various forces and moments and determine the beating trajectory of the wheel. At the same time, it also has a certain friction damping effect. In addition, the leaf spring also has the function of a guide device, which can guide and transmit force.

[0004] Taking the front suspension leaf spring as an example, when installing the leaf spring, the middle part is pre-installed on the crossbeam of the frame through the leaf spring bracket, and the two ends of the leaf spring need to be connected to the upper control arms on the left and right sides. At present, when installing the ends of the leaf spring, it is easy to cause the leaf spring to move along its own width direction, which makes the installation of the leaf spring and the upper control arm difficult and the installation efficiency low. In addition, during the installation process, the leaf spring is easily damaged due to improper operation, which is not conducive to ensuring the performance of the leaf spring.

[0034] In the description of the present invention, it should be noted that if there are terms indicating orientation or positional relationship such as "upper", "lower", "inner", "back", etc., they are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, if there are terms such as "first", "second", etc., they are also used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] This embodiment relates to an auxiliary tool for installing a leaf spring, which is used to assist in installing a leaf spring 4. Figure 1 As shown in the figure, the leaf spring 4 is taken as a front suspension leaf spring for illustration. The middle part of the leaf spring 4 is fixed to the crossbeam 301 of the frame 3 through the leaf spring bracket 401, and the auxiliary tooling in this embodiment can be used to assist the end of the leaf spring 4 to be connected to the upper control arm in the control arm assembly.

[0037] In terms of overall structure, the auxiliary tooling for installing the leaf spring in this embodiment includes a main body 1 that can be positioned on the vehicle frame 3, and a limiting part 2 provided on two opposite sides of the main body 1 along a first preset direction. The two limiting parts 2 are used to clamp on both sides of the leaf spring 4 in the width direction to limit the displacement of the leaf spring 4 in its own width direction, and the spacing between the two limiting parts 2 is adjustable.

[0038] The auxiliary fixture for installing the leaf spring described in this embodiment can limit the displacement of the leaf spring 4 in the width direction of the leaf spring 4 through the two limiting parts 2, thereby improving the installation efficiency of the leaf spring 4. And the adjustable spacing between the two limiting parts 2 not only enables the auxiliary fixture to assist in the installation of leaf springs 4 with different widths, thus having good versatility. Moreover, during the installation of the leaf spring 4, the adjustable spacing between the two limiting parts 2 also facilitates the loading and unloading of the auxiliary fixture on the vehicle frame 3.

[0039] Based on the above overall introduction, the exemplary structure of the auxiliary tooling described in this embodiment is as follows Figure 2 and Figure 3 As shown in . The main body 1 is in the shape of a plate as a whole, and can be positioned on the crossbeam 301 of the frame 3, and is located between the two longitudinal beams 302. In order to facilitate the positioning of the main body 1 on the crossbeam 301, in this embodiment, a positioning column 102 is provided on one of the main body 1 and the frame 3, and a positioning hole for inserting the positioning column 102 is provided on the other of the two. The main body 1 is positioned on the frame 3 by inserting the positioning column 102 into the positioning hole. The positioning column 102 and the positioning hole have simple structures, and the positioning effect of the two is good.

[0040] In some embodiments, two positioning posts 102 are spaced apart and arranged at both ends of the main body 1, and two positioning holes are arranged on the crossbeam 301 corresponding to the positioning posts 102. The insertion of the two positioning posts 102 in the corresponding positioning holes helps to further ensure the positioning effect of the main body 1 on the crossbeam 301. Of course, the number of positioning posts 102 here can also be adaptively adjusted as long as the positioning requirements are met.

[0041] The first preset direction in this embodiment is arranged parallel to the width direction of the main body 1 and the width direction of the leaf spring 4. As a preferred embodiment, at least one of the limiting parts 2 includes a side plate 201 connected to the main body 1, a limiting block 202 arranged on the side plate 201 for sliding along the first preset direction, and an adjusting member 203 connected to the limiting block 202. The adjusting member 203 is used to receive external force and drive the limiting block 202 to approach or move away from another limiting part 2 to adjust the distance between the two limiting parts 2. Here, the structures of the side plate 201 and the limiting block 202 are simple, and the setting of the adjusting member 203 is conducive to driving the limiting block 202 to slide, thereby facilitating the adjustment of the distance between the two limiting parts 2.

[0042] Furthermore, each limiting part 2 in the present embodiment includes a side plate 201, a limiting block 202 and an adjusting member 203. The adjustable spacing between the two limiting parts 2 specifically refers to the adjustable spacing between the two limiting blocks 202, and the two limiting blocks 202 are respectively abutted against both sides of the end of the leaf spring 4, thereby limiting the displacement of the leaf spring 4 along its own width.

[0043] As a feasible implementation, the adjusting member 203 in this embodiment includes a screw rod rotatably arranged on the side plate 201, and one end of the screw rod is screwed to the limit block 202. A limit portion for limiting the rotation of the limit block 202 is provided between the limit block 202 and the side plate 201. The structure of the screw rod is simple and easy to arrange and implement. By providing the limit portion, it is beneficial to prevent the limit block 202 from rotating, thereby ensuring the use effect of the limit block 202.

[0044] In specific implementation, a retaining spring is provided on the screw rod, and a slot for the retaining spring to be inserted is provided on the side plate 201. The displacement of the screw rod along its own axial direction can be limited by the cooperation of the retaining spring and the screw rod can only rotate around its own axial direction. A threaded blind hole is provided on the side of the limit block 202 facing the side plate 201, and the output end of the screw rod is screwed to the threaded blind hole. In addition, relative to the limit block 202, an operating head is also provided at the other end of the screw rod. By screwing the operating head, the screw connection length between the limit block 202 and the screw rod can be changed, and under the action of the limit portion, the limit block 202 can only move along the axial direction of the screw rod, that is, slide relative to the side plate 201. In addition, the screw rod and the limit block 202 are screwed to each other, which is also convenient for disassembly between the two.

[0045] like Figure 2 and Figure 3 As shown in the figure, the limiting part in this embodiment includes a limiting column 2023 slidably arranged on the side plate 201 along the first preset direction, and the limiting column 2023 is connected to the limiting block 202 to limit the rotation of the limiting block 202. Corresponding to the limiting column 2023, a limiting hole 2012 is provided on the side plate 201 for the limiting column 2023 to pass through. Under the cooperation of the limiting column 2023 and the screw rod, the rotation of the limiting block 202 can be limited. Of course, the number of the limiting column 2023 can be two, which are arranged on both sides of the screw rod, in addition to the one shown in the figure.

[0046] In order to further improve the use flexibility of the auxiliary tooling, in this embodiment, Figure 2 and Figure 3 As shown in , a plurality of connection holes 2011 are provided on the side plate 201 and are arranged at intervals along the second preset direction. The adjusting member 203 can selectively pass through any of the connection holes 2011, and the position in the second preset direction is adjustable, and the second preset direction is perpendicular to the first preset direction. The second preset direction here is also the height direction of the frame 3. The screw in this embodiment is specifically rotatably arranged in the connection hole 2011. By providing a plurality of connection holes 2011, and the adjusting member 203 can selectively pass through the connection hole 2011, it is convenient to adjust the height of the limit block 202, thereby facilitating the limiting of leaf springs 4 of different thicknesses, and having good versatility.

[0047] In addition, the limiting holes 2012 in this embodiment are also arranged in a plurality along the second preset direction and are arranged one-to-one corresponding to the connecting holes 2011. When the screw rods are located in different connecting holes 2011, the limiting posts 2023 can be inserted into the corresponding limiting holes 2012, thereby ensuring the convenience and flexibility of adjusting the position of the limiting block 202.

[0048] It should be noted that, in the specific implementation, in addition to using a screw rod as the adjusting member 203 and adjusting the position of the limit block 202 by screwing the screw rod, a cylinder can also be arranged on the side plate 201. At this time, the power output end of the cylinder is directly connected to the adjusting member 203, and the limit block 202 can also be driven to slide, thereby adjusting the distance between the two limit parts 2. However, the scheme of using a screw rod as the adjusting member 203 not only has a higher operating accuracy, but also can adjust the position of the limit block 202 in a small range according to the distance between the limit block 202 and the leaf spring 4, which is conducive to improving the adjustment accuracy of the limit block 202.

[0049] Still refer to Figure 2 and Figure 3 As shown in , the upper protrusion 2021 on the limit block 202 of this embodiment abuts against the top layer of the leaf spring 4, limiting the upward displacement of the leaf spring 4, which helps prevent the leaf spring 4 from warping up during installation. In addition, the bottom of the limit block 202 is provided with a lower protrusion 2022 protruding toward the other limit part 2, and the lower protrusion 2022 can support the bottom layer of the leaf spring 4 and limit the downward displacement of the leaf spring 4. The lower protrusion 2022 on the limit block 202 can support the leaf spring 4, which helps prevent the installation of the leaf spring 4 with the upper control arm from being affected due to the position of the leaf spring 4 being too downward, thereby helping to further ensure the installation efficiency of the leaf spring 4. In addition, the upper protrusion 2021 and the lower protrusion 2022 have simple structures, are easy to arrange and implement, and have a good limiting effect.

[0050] like Figure 2 As shown in , in this embodiment, both ends of each side of the main body 1 are provided with a limiting portion 2 to limit the displacement of both ends of the leaf spring 4 in the width direction thereof. That is, both opposite sides of each end of the main body 1 are provided with a limiting portion 2. The two limiting portions 2 at the same end cooperate to clamp and limit one end of the leaf spring 4. Here, the limiting portions 2 are provided at both ends of each side of the main body 1, which is conducive to improving the limiting effect on both ends of the leaf spring 4, and further conducive to improving the installation efficiency of the leaf spring 4.

[0051] Still refer to Figure 2 and Figure 3As shown in , the main body 1 is provided with an avoidance hole 103, and the avoidance hole 103 is used to avoid the components on the frame 3. Here, the avoidance hole 103 can be set on the main body 1 corresponding to the top of the leaf spring support 401, and the component can be a connecting component connecting the leaf spring support 401 and the crossbeam 301. The components on the frame 3 are avoided by the avoidance hole 103, which is conducive to ensuring the positioning effect of the main body 1 on the frame 3. In addition, the main body 1 is provided with a handle 101. The handle 101 is set at the top of the main body 1 and is set across the avoidance hole 103. The handle 101 is provided to facilitate holding the main body 1, thereby facilitating the installation and removal of the auxiliary tooling on the frame 3.

[0052] When the auxiliary tooling for installing the leaf spring in this embodiment is used, the adjusting members 203 are first screwed so that the spacing between the limiting blocks 202 is larger than the width of the leaf spring 4. The main body 1 can be positioned on the frame 3 by inserting the positioning column 102 on the main body 1 into the positioning hole on the crossbeam 301, and the limiting parts 2 are located outside the width direction of the leaf spring 4. Then, the adjusting members 203 are screwed so that the limiting blocks 202 abut against the side of the leaf spring 4, and the end of the leaf spring 4 can be limited in the width direction. At this time, the end of the leaf spring 4 can be installed.

[0053] When the height of the limit block 202 needs to be adjusted, the limit block 202 and the adjusting member 203 are separated, and then the adjusting member 203 is removed from the connection hole 2011, and the limit column 2023 is removed from the limit hole 2012. Then the adjustment member 203 is connected to the corresponding connection hole 2011, the limit column 2023 is inserted into the corresponding limit hole 2012, and then the limit block 202 and the adjusting member 203 are screwed together.

[0054] The auxiliary tooling for installing the leaf spring in this embodiment can not only limit the leaf spring 4 in the width direction, but also limit the upward and downward displacement of the leaf spring 4 according to the use requirements, which is beneficial to further improve the installation efficiency of the leaf spring 4. In addition, the position between the limit blocks 202 is adjustable, which is beneficial to the convenience of disassembly of the auxiliary tooling on the frame 3, and can also limit the leaf springs 4 of different widths. In addition, making the position of the limit block 202 adjustable in the height direction is also beneficial to meeting the installation requirements of the leaf springs 4 at different heights, so that it has good versatility, and the auxiliary tooling has a simple structure, is easy to arrange and implement, and is easy to operate, and has good promotion significance.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
