A rear suspension assembly for buses and other vehicles has a square rubber torque spring, whose particular construction and components favorably increase the load capacity of the bus, result in a reduction of maintenance time and better safety and comfort conditions during operation of the bus. The rear suspension includes an upper support and a complementary lower support to clamp the rubber torque spring and attach the spring to the vehicle frame. The upper and lower supports are united by a pair of U-shaped clamps. The U-shaped clamps extend through a lower mounting seat to fasten the spring and the upper and lower supports with a rear axle of the bus by hexagonal self-locking nuts. The assembly is joined to the bus body by a pair of suspension arms extending between the spring and a coupling mounted on the vehicle frames. The rear suspension assembly also includes a pair of adjustment levers connected to hexagonal blocks provided on each end of the square torsion spring. Brackets extend from the upper support connecting a pair of shock absorbers from the vehicle frame to the spring assembly.
