Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle suspension technical field especially relates to a nut anti -rotation mechanism that can be applied to suspension system. BACKGROUND

[0002] The statements in this section merely provide background information related to the utility model and do not necessarily constitute prior art.

[0003] The rubber suspension system is used to support the weight of the power assembly (engine and gearbox), and simultaneously suppresses the vibration and displacement of the power assembly, wherein the rubber in the rubber suspension system mainly plays a buffering and vibration isolation role. The current rubber suspension system adopts a mechanical nut mode for fixing, but the existing engineering mechanical nut fixing is mostly a standard bolt and nut fixing type, and when the space is narrow and the nut cannot be tightened, a fixed nut is mostly used. In the rubber suspension system, there are loss parts such as rubber cushions, and during the long-term use of the rubber suspension system, the rubber cushions and other components will inevitably be worn out.

[0004] On the one hand, when the rubber cushions and other loss parts are replaced, the nuts need to be rotated to realize the replacement of the loss parts, but the threads of the nuts are easily damaged when the nuts are frequently disassembled, and the nuts can only be cut off and re-welded when used again, which is time-consuming, laborious and inconvenient to maintain. On the other hand, when the rubber cushions and other loss parts are replaced, the disassembly operation space is not considered. SUMMARY

[0005] In view of the above defects or improvement needs of the prior art, the utility model provides a nut anti-rotation mechanism that can be applied to a suspension system, which comprises a nut fixing device, the nut fixing device comprises a fixed plate, a nut and a locking plate, and the nut is welded to the lower surface of the fixed plate through the locking plate.

[0006] It also comprises a suspension system, the suspension system comprises a support assembly and a suspension system connecting assembly, the support assembly comprises an L-shaped support, the L-shaped support comprises a first panel and a second panel, the first panel and the second panel are perpendicular to each other and welded together, the suspension system connecting assembly comprises a limiting plate, a bolt, a bottom plate and a rubber cushion, both sides of the first panel are provided with rubber cushions, and the rubber cushions are sequentially arranged from top to bottom as a first rubber cushion and a second rubber cushion, the side of the first rubber cushion away from the first panel is provided with a limiting plate, and the side of the second rubber cushion away from the first panel is provided with a bottom plate, the bottom plate is fixed to the upper surface of the fixed plate, and the bolt sequentially penetrates the limiting plate, the first rubber cushion, the first panel, the second rubber cushion, the fixed plate and the nut from top to bottom, and is finally fixed at the nut.

[0007] The above one or more technical solutions have the following beneficial effects:

[0008] 1. Since the nut of this utility model is directly fixed to the fixing plate by welding, when it is necessary to maintain the suspension soft pad connection assembly, the maintenance personnel only need to loosen the bolt upwards to remove and replace the first soft pad or the second soft pad. The nut does not need to be rotated or the whole assembly needs to be replaced during the entire maintenance process. This makes up for the technical defect of the prior art that the threads are damaged due to repeated rotation of the nut, and greatly reduces the number of times the nut needs to be replaced.

[0009] 2. When it is necessary to replace the nut, simply loosen the screw upwards, cut off the damaged nut with a cutting tool, and re-weld a new nut to the base plate. The whole process is time-saving and labor-saving, and the requirements for disassembly space are small during the replacement process, which can be completed in a small disassembly space.
