  • Anti-creep trailer locking mechanism
    Patent number: 7293781
    Abstract: An anti-creep locking mechanism for a trailer suspension system is disclosed. The disclosed locking mechanism includes at least one column that may be swung into a first position in a gap formed between a trailer frame and a suspension component to keep a trailer at a predetermined height. The column is biased into the first position by a spring. An actuator, such as a contracting air bag or an air cylinder with a linkage assembly, is used to overcome the biasing force of the spring and retract the column into a second position, thereby deactivating the anti-creep locking mechanism. The anti-creep mechanism may further include an angle limiter to insure that column is fully retracted once the system is deactivated.

  • Trailing arm for a vehicle suspension
    Publication number: 20060181047
    Abstract: A trailing arm has a first side portion with an axle recess and a second side portion with an axle recess. An upper portion of the trailing arm is defined at least partially by overlapping portions of the first side portion and the second side portion. The overlapping portions define a weld aperture in the upper portion and a suspension aperture.
