    摘要： A suspension unit for supporting a cab on the chassis of a truck has two U-shaped yokes, one with arms extending down and the other with arms extending up. The arms of one yoke are nested within the arms of the other in a sliding fit and a bearing in a vertical slot connects each pair of adjacent arms. An air spring and one or two shock absorbers can be mounted between the yokes. A guideway having a bottoming rib or a stop element with a cushioning pad is formed on one of the arms of each adjacent pair and the other arm of the corresponding pair is received within the guideway and abuts the bottoming rib or stop element in a fully compressed position to prevent excessive loads on the air spring, shock absorbers and bearings. The unit is mounted on a truck between the cab and chassis with one pair of adjacent arms fore and the other pair aft, to provide relatively free vertical movement, pivoting about a fore and aft axis, and fore and aft translational rigidity of the truck cab relative to the chassis.

    摘要： A linear preload fluid power operated latch has two coaxial pistons, one slidable inside the other and the other slidable within a cylinder. The one piston slides inside the other to cam dogs which are slidable in slots of a nose which is secured to the other piston so as to engage an undercut in a cup in which the nose is received. After the dogs are engaged in the cup, which secures the latch, both pistons are retracted to apply a linear preload force between the two bodies being latched. In one embodiment, the pistons are moved in both directions under fluid pressure and in another embodiment, both pistons are returned by compression springs. In either case, the cup is drawn closer to the cylinder with a certain preload force, to latch a body to which the cup is attached to a second body to which the cylinder is attached with that preload force. An elastomeric isolator is interposed-between the one body and the cup so as to attenuate the transmission of vibrations from the cup to the body or vice versa, and also to provide lateral and vertical compliance for helping to align the cup and locking unit with one another.
