The invention discloses an automobile spring with high deformation resistance. The automobile spring comprises an upper fixed steel plate spring and a lower fixed steel plate spring, a plurality of middle steel plate springs are arranged between the upper fixed steel plate spring and the lower fixed steel plate spring, the inner side of the middle steel plate spring is provided with an anti-deformation mechanism, the anti-deformation mechanism comprises an anti-deformation spring and a fixed sliding plate, the middle steel plate springs are divided into two sections, the fixed sliding plates are fixedly arranged at one ends of the two sections of middle steel plate springs, the anti-deformation springs are fixedly arranged between the fixed sliding plates, and fixed buckles are arranged onthe surfaces of the two ends of the upper fixed steel plate spring and the middle steel plate spring. The anti-deformation mechanisms, when the steel plate spring is used, the impact force can be bent, buffering is carried out through the elasticity of the anti-deformation spring in the anti-deformation mechanism during bending, and deformation and damage caused by impact force for a long time are prevented.
