Abstract:
This study examined various types of coil spring compressors in the automobile
industries. A coil spring compressor for compressing a coil spring during the assembly
of subassemblies of automotive suspension systems, having a head jaw positioned
above a base and movable with respect to the base. The coil spring compressor is
provided with a pair of guide bars suspended from the head plate and on which a
slidable carriage is mounted. The carriage carries a pair of compressing assemblies
facing each other in the vertical positions and positioned at both the upper and lower
parts of the coil spring. Each assembly comprises a pair of compressor arms
interconnected with each other. Each compressor arm is provided with a jaw mount to
which a compressing hook is adjustably attached. The jaws are introduced between
some few successive turns of the coil spring by operating handles provided on the
compressor arms. The purpose of this design is to be use on various types of suspension
disassembly and assembly of vehicles, the tool includes the upper and the lower jaw
which by the smooth turning of the screw lowers to compress the coil spring or turns to
release the compressed coil spring. The new design was made from mild steel and tools
used for the construction are Electric arc welding machine, power and hand hacksaws,
the bench vice, assorted hammers, vice, etc. The findings indicated that the new design
is more efficient than the existing one. It was also recommended that car owners who
visit the workshop should insist on the use of the right compression tool in the
disassemble and assemble of their suspension systems.
