The invention provides an inerter suspension of a vehicle, and belongs to the field of a vehicle suspension. According to the inerter suspension of the vehicle, an auxiliary spring is connected with an inerter in parallel and then is connected with a damper in series, and in order to solve the problem of overload failure of a passive mechanical element because of bearing for the vehicle body weight, a main spring is added and connected in parallel with a two-stage structure formed by the auxiliary spring, the inerter and the damper. Compared with a traditional suspension, the performance of the inerter suspension is remarkably improved, and three vehicle running smoothness evaluation indexes including a vertical acceleration root-mean-square value of a vehicle body, a dynamic travel root-mean-square value of the suspension and a dynamic load root-mean-square value of each tire are remarkably reduced. The novel inerter suspension of the vehicle has certain application value in the field of the vehicle suspension.
