In addition, due to its large size, the chassis trailer in use requires more than one person to push it during the transportation process. During the chassis assembly process, the spring reaction force of the suspension coil spring causes the body to be lifted in the opposite direction, and the suspension cannot be assembled to the body. It is necessary to add counterweight to the body to eliminate the spring reaction force before the assembly can be completed. Utility Model Content

[0039] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0040] As Figures 1 to 7 shown, the present utility model provides an auxiliary tool for chassis suspension installation, which includes a guide shaft 100 and a support platform 200. Among them, an external thread 110 is provided on the side wall of the guide shaft 100; the support platform 200 includes a housing 210, a top block 220, and an axial lifting body 230. One end of the housing 210 is provided with an installation hole 211, the other end of the housing 210 is provided with a rotation hole 212, the top block 220 is arranged in the installation hole 211, the axial lifting body 230 is rotatably connected to the rotation hole 212, and a threaded hole 234 is opened in the axial lifting body 230. The threaded hole 234 is screwed with the external thread 110 of the guide shaft 100. Through the above structure, the guide shaft 100 is passed through the support platform 200, and the support platform 200 can move along the guide shaft 100.

[0041] When the auxiliary tool for chassis suspension installation provided by the present utility model is in use, first connect and tighten the external thread 110 of the guide shaft 100 with the screw hole of the vehicle body, and then sleeved the assembly hole on the suspension onto the guide shaft 100. The assembly hole on the suspension is a structure that is aligned with the screw hole of the vehicle body. The assembly hole and the screw hole are used when connecting and fixing the suspension to the vehicle body. Align the assembly hole on the suspension with the guide shaft 100 and move the suspension towards the vehicle body to sleeved the assembly hole on the suspension onto the guide shaft 100. Then, screw the external thread 110 of the guide shaft 100 with the threaded hole 234 of the axial lifting body 230, and the top block 220 abuts against the suspension. Then rotate the axial lifting body 230. Since the axial lifting body 230 is screwed with the external thread 110 of the guide shaft 100 through the threaded hole 234, the rotation of the axial lifting body 230 will drive the top block 220 to move linearly along the guide shaft 100, and the top block 220 pushes the suspension upwards to be combined with the vehicle body. During the installation of the suspension, four sets of auxiliary tools for chassis suspension installation can be used according to the use requirements. After the suspension is combined with the vehicle body, remove any set of auxiliary tools for chassis suspension installation and replace it with a standard bolt. The standard bolt passes through the assembly hole on the suspension and is threadedly connected with the screw hole of the vehicle body, and tighten the standard bolt. The same operation is performed for the other three sets in turn to complete the installation of the suspension. This auxiliary tool for chassis suspension installation can overcome the spring force of the chassis suspension without using a positioning fixture and a chassis tray fixture, improve the installation efficiency of the chassis suspension, and has the characteristics of low cost, ingenious structure, small and portable, and general-purpose.

[0042] The specific removal process of the chassis suspension installation auxiliary tool is: loosen the external thread 110 and the thread of the vehicle body, separate the guide shaft 100 from the vehicle body, and then pull the guide shaft 100 out of the assembly hole on the suspension.

[0043] During use of the chassis suspension installation auxiliary tool, since the threaded hole 234 rotates relative to the external thread 110, a brush or an injection needle can be used to add grease to the threaded hole 234, thereby ensuring the smooth rotation of the axial lifting body 230 and reducing the wear of the threaded hole 234 and the external thread 110.

[0044] In some embodiments, the diameter of the rotating hole 212 is smaller than the diameter of the mounting hole 211, and a first limiting ring 232 is provided at one end of the axial lifting body 230. The first limiting ring 232 is arranged in the mounting hole 211. Through the above structure, the axial lifting body 230 can be prevented from separating from the shell 210.

[0045] The support platform 200 further includes a plane bearing 240, which is disposed in the mounting hole 211 and is located between the top block 220 and the axial lifting body 230. The upward rotation force of the axial lifting body 230 is converted into an upward thrust on the top block 220 through the plane bearing 240. Due to repeated use, the plane bearing 240 needs to be added with grease at regular intervals. When lubricating the plane bearing 240, a brush or an injection needle can be used to add grease into the plane bearing 240 through the threaded hole 234, thereby ensuring the smoothness of rotation and the service life of the plane bearing 240 and reducing the occurrence of wear of the plane bearing 240.

[0046] In some embodiments, a second limiting ring 222 is provided at one end of the top block 220 close to the axial lifting body 230, and a ring groove 213 is provided on the inner wall of the mounting hole 211. A locking spring ring 214 is embedded in the ring groove 213, and the locking spring ring 214 abuts against one end of the second limiting ring 222 away from the axial lifting body 230. Through the above structure, the top block 220 can be limited between the housing 210 to prevent the top block 220 from being separated from the housing 210.

[0047] The top block 220 is provided with a through hole 221 coaxial with the mounting hole 211, and the guide shaft 100 passes through the through hole 221, so that the top block 220 can move along the guide shaft 100. When lubricating the plane bearing 240, grease can be added into the plane bearing 240 through the through hole 221 using a brush or an injection needle.

[0048] In some embodiments, a first connection end 120 is provided at one end of the guide shaft 100, and the first connection end 120 can be detachably connected to a wrench or a standard wrench tool, so that the guide shaft 100 can be rotated by using a wrench or a standard wrench tool, thereby facilitating tightening the external thread 110 of the guide shaft 100 with the screw hole of the vehicle body.

[0049] Optionally, a connecting rod 130 is provided at one end of the guide shaft 100 away from the first connection end 120, and a threaded end 131 is provided at one end of the connecting rod 130 away from the guide shaft 100. By providing the connecting rod 130, the use distance of the guide shaft 100 can be increased, and the threaded end 131 can be selected to replace the external thread 110 to connect with the screw hole of the vehicle body. Specifically, the connecting rod 130 can be detachably connected or fixedly connected to the guide shaft 100. The first connection end 120 can be a regular hexagon or other regular polygon, so as to adapt to a wrench or a standard wrench tool.

[0050] In some embodiments, the end of the axial lifting body 230 away from the top block 220 is provided with a second connection end 233; the chassis suspension installation auxiliary tool also includes a sleeve 300, one end of which is provided with an adapter sleeve 310, the adapter sleeve 310 is detachably connected to the second connection end 233, and the sleeve 300 is rotated to drive the axial lifting body 230 to rotate. Specifically, the adapter sleeve 310 is provided with a polygonal connection hole 311 along the axis, and the second connection end 233 is a polygonal body that matches the polygonal connection hole 311, so as to realize the detachable connection between the adapter sleeve 310 and the second connection end 233, and at the same time facilitate the rotation of the axial lifting body 230.

[0051] In some embodiments, an adapter end 320 is provided at one end of the sleeve 300 away from the axial lifting body 230, and the adapter end 320 can be detachably connected to a wrench or a standard wrench tool, so that the sleeve 300 can be rotated by the wrench or the standard wrench tool, so that the axial lifting body 230 can be driven to rotate relative to the guide shaft 100 by the sleeve 300. The sleeve 300 can be, but is not limited to, a double-headed hollow sleeve.

[0052] In some preferred embodiments, the axial lifting body 230 is provided with a turntable 231, and the turntable 231 is rotatably connected to the rotary hole 212, so that the axial lifting body 230 can rotate relative to the rotary hole 212. The mounting hole 211 is coaxially arranged with the rotary hole 212, so as to avoid interference between the axial lifting body 230 and the mounting hole 211 during the rotation of the axial lifting body 230 relative to the rotary hole 212. The mounting hole 211 is coaxially arranged with the threaded hole 234, so as to avoid interference between the guide shaft 100 and the mounting hole 211.

[0053] It should be noted that wrenches or standard wrenching tools are relatively mature disassembly and assembly tools in the prior art, and the vehicle body and suspension are also existing structures. Moreover, wrenches, standard wrenching tools, vehicle bodies, and suspensions are not the objects to be protected by the present utility model. Therefore, no further elaboration will be made here.

[0054] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here.
