The invention provides a clutch pedal assembly. The clutch pedal assembly comprises a pedal arm, a pedal support and an extension spring, and further comprises a torsion spring and a torsion spring support. The connection line between a positioning point of the torsion spring and the pedal support and a positioning point of the torsion spring and the torsion spring support is located on one side, close to the pedal support, of the connection line between a positioning point of the torsion spring and the pedal support and a fixing point of a rotary shaft and the pedal support. The sum of restoring force of the extension spring and force transmitted to the pedal arm by the inner pressure of a clutch master cylinder is equal to the elastic force of the torsion spring before the pedal arm rotates. By limiting the positioning point of the torsion spring and the fixing point of the torsion spring support, it is ensured that the torsion spring continuously applies rotation thrust on the pedal arm, and the sense of heaviness is effectively avoided when a pedal is used; and through restoring force provided by the extension spring to the pedal arm, it is ensured that after the pedal is released, the pedal arm can restore in time.
