The invention discloses a spring booster, a clutch pedal assembly and a vehicle. The spring booster comprises a sleeve bracket fixedly connected to a base, a mandrel bracket hinged with a pedal arm, an outer side spring covering the external of a component formed by fitting the sleeve bracket and the mandrel bracket, an inner side elastic component positioned in the sleeve bracket and coaxial with the outer side spring, and a slide mechanism arranged on the sleeve bracket; under the effect of pedal force, the mandrel bracket can axially move from a first position of the sleeve bracket to a second position of the sleeve bracket corresponding to the sleeve bracket; in the process from the first position to the second position, the slide mechanism compresses and limits the inner side elastic component; and in the second position, the inner side elastic component is deviated from the limitation of the slide mechanism to freely expand. The spring booster can improve the clutch pedal boosting value under the preconditions of guaranteeing proper pedal travel and proper maximum pedal return force.
