Abstract: A rear suspension system for automobiles, comprising: a trailing arm pivoted to the automobile body at its front end and to a knuckle at its rear end; a first and a second lateral links extending laterally across an upper portion and a lower portion of the knuckle and the corresponding locations of the automobile body, respectively; and a third lateral link extending laterally across an intermediate position of the knuckle, located between the upper portion and the lower portion of the knuckle and behind a central axial line of a wheel axle of the knuckle, and the corresponding location of the automobile body. The second lateral link has a substantially same length as the third lateral link. Thus, the mounting positions of the lower end of the shock absorber can be lowered, and the resistance against the changes in the toe angle and the camber angle is increased.

Abstract: The purpose of this invention is to allow the lubrication of a ball and coupler while being attached together. Unity of a ball and coupler are essential to this invention. The size of ball is immaterial to the function of the design. Lubrication is accomplished through a system comprising of internal ports and external exiting port holes. An internal port system that comprising a variety of ports and exiting port holes to the surface of the ball at various angles allowing lubrication between the ball and socket of the coupler. An external lubrication fitting is attached to the internal lubrication port system. Pressurization occurs when an external lubrication is introduced into the internal porting system through the external lubrication fitting. The amount of lubrication to the ball and socket is controlled by the amount of lubrication introduced into the internal porting system via the lubrication fitting.

By timely use of the key actuated switch, the anti-theft device can be turned on and off to secure the automotive vehicle.
Abstract: A tension actuator suspension system is disclosed, providing control over the elevation of a load suspended from a reference system, as well as over the compliance of the suspension system. As employed in a vehicle suspension system, a preferred arrangement employs radially expansible, axially contractible tension actuators exhibiting tensile forces that decrease nonlinearly as each contracts. An antagonistic actuator pair is arranged in opposition between the chassis and each wheel of the vehicle. Air is supplied to the actuators from a compressor and accumulator by lines under the control of pressure regulator valves. Manual or automatic inputs allow the adjustment of both vehicle chassis elevation and suspension system compliance individually with respect to each wheel.
