Abstract
Abstract A trailing link type beam suspension suitable for use as the rear suspension of a front-drive type automobile. The beam suspension comprises a hollow axle beam having a left first end and a right second end to which left and right wheels are connected rotatably; a first trailing arm having one end fixed to the first end of the axle beam and the other end connected to the chassis; a second trailing arm having one end rotatably connected to the second end of the axle beam and the other end connected to the chassis; a stabilizer received by the hollow axle beam and having one end fixed to the first end of the axle beam and the other end swingably supported by the second end of the axle beam; and a link through which the other end of the stabilizer is connected to the second trailing arm. The stabilizer may be composed of a torque tube received by the hollow axle beam and fixed at one end to a portion of the latter adjacent to the second end thereof, and a torsion bar non-rotatably fixed at its one end to the other end of the torque tube and swingably supported at its other end by the one end of the torque tube.
