The invention discloses an auxiliary spring, a suspension and a vehicle, relates to the technical field of automobiles, and aims to solve the problem that irreversible damage is caused by overlarge deformation of the suspension when the suspension encounters overlarge impact. The auxiliary spring comprises a first plate body, a second plate body and a first buffer layer, the first plate body and the second plate body are arranged in a spaced mode, and the first buffer layer is connected between the first plate body and the second plate body. A first limiting structure is arranged on the side, close to the second plate body, of the first plate body and can abut against the second plate body. The first limiting structure can play a limiting role, and the maximum displacement of the first plate body relative to the second plate body is the distance from the first limiting structure to the second plate body when the auxiliary spring is in a static state.
本申请公开了一种副簧、悬置及车辆,涉及汽车技术领域,用于解决悬置在遇到过大的冲击时,其变形量过大导致产生不可逆的破坏的问题。该副簧包括第一板体、第二板体和第一缓冲层,第一板体和第二板体间隔设置,第一缓冲层连接于第一板体和第二板体之间。第一板体靠近第二板体一侧设置有第一限位结构,第一限位结构能够与第二板体抵接。第一限位结构能够起到限位的作用,第一板体相对第二板体运动的最大位移量为副簧处于静态时,第一限位结构到第二板体的距离。
