The invention provides a spiral spring for a vehicle suspension. The spiral spring has continuous pitch identical sections and pitch transition sections; the pitch transition sections are configured to be gradually pressed when the sprung mass is changed from no load to full load; and in the section from no load to full load, the sprung mass and the working lap number of the spiral spring satisfy the following relation as shown in the description, wherein G is the material elastic modulus of the spiral spring, f is the vehicle offset frequency, d is the spring wire diameter of the spiral spring, D is the spring medium diameter of the spiral spring, m is the sprung mass, n is the working lap number, and f is the constant. The invention further provides an independent suspension assembly adopting the spiral spring and a vehicle adopting the spiral spring. The spiral spring for the vehicle suspension, the independent suspension assembly and the vehicle have the advantages of good smoothness and long service life.
