The invention relates to a linear motor shock absorber used for an automobile in-wheel active suspension, and belongs to the technical field of automobile accessories. The linear motor shock absorber mainly comprises a motor shock absorber body, supports, wheels, a passive suspension spring and a passive shock absorber body. The motor shock absorber body is arranged in the wheels through the supports and comprises a peripheral magnetic insulation sleeve, end covers, a rotor, a stator and linear cylindrical slide rails. The stator comprises a cylindrical supporting shaft, annular stator magnetic conduction back iron, annular S-pole permanent magnets and N-pole permanent magnets. The rotor comprises an annular rotor iron core magnetic conductor, winding coils, Hall sensors, annular grooves and rotor teeth. The movable ring structure with the stator on the inner portion and the rotor on the outer portion is adopted for the motor shock absorber body. The rotor can slide up and down along the stator through the cylindrical slide rails. The motor shock absorber body is connected with the passive suspension spring and the passive shock absorber body in parallel, wherein the passive suspension spring and the passive shock absorber body are arranged outside the wheels. The linear motor shock absorber used for the automobile in-wheel active suspension has the advantages that the operation force is adjustable, passive energy recovery is achieved, the size is small, and the stroke is large.
