Description

Technical Field

[0001] The utility model relates to the technical field of bushing disassembly and assembly devices, in particular to a hydraulic bushing disassembly and assembly device for an automobile control arm. Background Art

[0002] Control arm hydraulic bushings are mechanical components that work by creating a gap between the inner and outer surfaces. They are commonly used in hydraulic systems, particularly in automotive suspension systems. They combine hydraulic technology with bushing functionality to provide improved vibration damping and support.

[0003] When removing and installing the existing hydraulic bushing disassembly and assembly device for an automotive control arm, the first step is to find a suitable fulcrum. The direction of force applied during the disassembly and assembly process varies, and therefore the position of the fulcrum also varies. Without a suitable fulcrum, the disassembly and assembly personnel will have difficulty effectively applying force, making the disassembly and assembly process complicated and time-consuming. Furthermore, an inappropriate fulcrum can cause uneven force on the bushing during disassembly and assembly, leading to deformation and damage. Therefore, we propose a hydraulic bushing disassembly and assembly device for an automotive control arm to address the aforementioned issues. Utility Model Content
