The invention relates to a double-trailing arm type steering independent suspension for an electric bus driven by wheel-side motors. The double-trailing arm type steering independent suspension comprises a left suspension, a right suspension, steering linkages, a steering rocker arm, an angle sensor and a steering actuating cylinder. According to the double-trailing arm type steering independent suspension disclosed by the invention, drive motors are arranged at wheel positions of the bus; each drive motor is located on the side of an output shaft of each of speed reducers; each speed reducer is fixed to each of supporting arms; the output shaft of each speed reducer penetrates through a center hole of each supporting arm and is connected with each of wheel-side structures of the bus, and a wheel of each wheel-side structure is driven to rotate, so that the driving to the bus is realized; the supporting arms are designed with high load-bearing performance to replace a conventional supporting arm structure, so that a shock absorber and a steering mechanism can be directly connected with the supporting arms, the steering and the locking of the bus are facilitated, and beside, the purposes of increasing the interior space of the bus and reducing the height of a bus floor can be realized.
