Abstract: A straight line linkage mechanism for a solid axle of a motor vehicle (referable to alternatively as a “Chan-Cameron mechanism” or as a “Chan-Cameron linkage mechanism”) includes a main bar, a tie rod and a shackle. The shackle is preferably configured as an “A-arm”, having its legs pivotally connected to a solid axle. The apex of the shackle is pivotally connected to a first end of the main bar. The opposite second end of the main bar is pivotally connected to the frame. The tie rod is pivotally connected at one end to a mid-range location of the axle and, at its opposite end, pivotally to a mid-point location of the main bar. The connection locations of the main bar are spaced apart twice as far as the connection locations of the tie rod. In operation, as the axle moves vertically relative to the frame in response to the wheels encountering irregular terrain, the first end of the main bar will tend to move horizontally. The shackle is mounted to the axle so that the apex thereof is horizontally movable. Accordingly, the axle is able to move vertically relative to the frame without a vertical arc component.

Abstract: A lifting shackle comprises a head plate (1) having a central aperture (4). A pair of load supporting arms (2) are each attached pivotably to the head plate at respective points substantially equi-distant from a vertical, in use, axis of the head plate passing through the aperture (4). The load supporting arms define facing channels which receive laterally spaced edges of the load. At or near the remote end of each load supporting arm (2) a load attachment bar (5) is provided for engaging the load to be lifted.

Abstract: A lower bearing air strut which moves the point of steering rotation of a dirigible road wheel to the bottom of the reservoir of the strut. This provides improved support between the road wheel assembly and the air strut and allows the air spring to be leak tested prior to vehicle assembly. The upper mount is fixed to the mounting tower by a retainer ring so it does not rotate and provides improved sealing of the upper extremity of the air spring.

Abstract: This suspension strut has upper and lower air sleeves which when pressurized with air provide the air spring suspension of a vehicle and which are axially offset from one another so that a force couple is formed that provides a moment which counteracts the moment resulting from the tire contact patch acting at a distance from the lower ball joint. With the tire contact moment neutralized, the side loads on the bearing and other sliding components of the strut are eliminated or sharply reduced to increase efficiency of strut operation and enhance strut durability.
