The invention relates to the technical field of automobile suspension, and provides an automobile suspension spring device and an automobile suspension system.The automobile suspension spring device comprises a first buffer part, at least one second buffer part, a suspension sealing cover, at least one first limiting set and a second limiting set, and the first buffer part is connected to an automobile body; the second buffer piece is arranged at the other end of the first buffer piece; the suspension sealing cover is movably arranged on the second buffer piece; the first limiting sets used for limiting the second buffering pieces to move in the telescopic direction of the second buffering pieces are arranged on the second buffering pieces in a one-to-one correspondence mode. The second limiting set used for limiting the suspension sealing cover from moving towards the first buffering piece is arranged on the suspension sealing cover. The first limiting set and the second limiting set are used for limiting stretching and retracting of at least one buffering piece and enabling other buffering pieces to stretch and retract. According to the automobile suspension spring device, stretching and retracting of part of the buffering pieces can be limited so that stress can be released, performance can be recovered, and the service life of the automobile suspension spring device can be prolonged.

    本申请涉及汽车悬挂技术领域,提供一种汽车悬挂弹簧装置及汽车悬挂系统,汽车悬挂弹簧装置包括第一缓冲件、至少一个第二缓冲件、悬挂封盖、至少一个第一限位组和第二限位组,第一缓冲件连接于车身;第二缓冲件设置于第一缓冲件的另一端;悬挂封盖可移动地设置于第二缓冲件上;用于限制第二缓冲件沿自身伸缩方向移动的第一限位组一一对应地设置于第二缓冲件上;用于限制悬挂封盖朝向第一缓冲件移动的第二限位组设置于悬挂封盖上;其中,第一限位组和第二限位组用于限制至少一个缓冲件的伸缩并使其它缓冲件能够伸缩。本申请提供的汽车悬挂弹簧装置能够限制部分缓冲件的伸缩以释放应力、恢复性能,延长汽车悬挂弹簧装置的使用寿命。
