The general passenger car .mast hive a 4 ^h l conf g i ns of wh ch the suspension sy sten of each wheel of the car most be installed. The suspension .sys em was d signee! to sup the load of the car transfer to the wheels which attached to the road sorface. The from sus ension of the car composed of the s u assembly which has the coil-spring placed oa top of the shock-absorber car ridie vvhich be m nted with the wheel at the lower end.

The. wheel and the strut-assembly will absor b t h e Impact force froro. the road siuihee to the strut tower of the body of the car. as when a pot-hole or hump on the mad sutfaee Is encountered that generated the impact force which will cause the car body of which part at ached to the strut tower to e fotigued (coieked or bene.

When the vehicle turn felt or right, the car body on the inside of the curve will be risen up due to die uen ibgal three, that eunse reduction to the pressure and eootaet of the wheel to the m d su hhee thus causing: understeeriug or oversteermg leaded to slippery and crashed.

Due to these mentioned problem, there be tatinvention to alleviate the stress of press ortihe top of the sttut^ower bei ieviag that wil 1 i nc reuse stahi hty of the strut-tow er that wi 11 pre vent mtd? rug of the ear body attached to the soau-fnwer and korease m e !irrnly atiaehnren! of the w heel to the road surface;.

For the cootentpor&ry original design, the strut- bar composed of the Mourning Plate (!) made of steeiplate cut into round shape to match with the top pari of the strut tower, the center pari: of the Mi¾mtia Plate ( ! ) was cu to he eirele shape, bi enough to let the tip of the shock absorber shaft to expose at the eeuter. At dre rim of th Mounting Plate (1.), the holes £5} will, he drilled, at the point that can be inserted by die bolt whkh was. f xed to ihe cap of the shock-absorber shaft and mounted together by outs. The Strut-Bar (2) made of metal such as statnless steel carbon steel or atomimi in Sat w round tube shape to be .fixed with the tab (4) welded at the inner rm of the MooMtng Plate fl). According to this design, the tbtee will transfer iifecil to bot opposite side v a the strut bar in horkootal direction that ees nor help to press on the top of the stmt tower which will not trarisier the pressure to ike wheel to kee the wheels firmly contact to the toad surface, OR th curving road swaying left a d right this does: not alleviate the problem of loss of wheel eont¾e to the road sia-faee, Purpos or Objec iv »f ibk im< ti

This new desigo. tor the Stnrt-I¾essed bar is to be uroursted OH top of the sirut-tower to resist twisting of the part of the body attached to the strut tower and create a resist ressure to the wheel when, it was im acted rt warel or downwatd due to the pot-hole m the temp or wa surface of the road ami o ¾¾a the ear ran i nto a curvy road, thai resist essure Will press the wheel to attach firroly to the road: surface.
