Coil And Rubber Type Patents (Class 267/33)
  • Patent number: 4260177
    Abstract: An independent front wheel suspension for motor vehicles has a support strut which includes a telescopic shock absorber and an enclosed coil spring which serves as the wheel spring. The piston rod of the telescopic shock absorber either alone or together with an upper wheel spring plate is resiliently supported at the vehicle body by a mounting arrangement having an annular elastomeric element. Several coupled and decoupled designs of mounting arrangements are disclosed. Each of the arrangements is characterized by an annular elastomeric element having a substantially axially aligned recess means in at least one of its two end faces for improved cardanic movability.

  • Patent number: 4256292
    Abstract: Suspension strut which incorporates a jounce bumper of a suitable rubber or elastomer having an outwardly oriented knee which yields under low axial compression to provide a low initial spring rate as the suspension initially contacts the bumper. As the suspension travel increases, the knee in the bumper wall continues to yield so that the internal shape of the walls of the jounce bumper become active and progressively increases the effective contact area to provide a progressively increasing spring rate and improved jounce control.

  • Patent number: 4219189
    Abstract: A spring support is disposed about and fixed to a shock-absorbing unit and engages the lower end of a coil spring. A spring base engages the upper end of the coil spring and engages a mounting plate which is secured to the vehicle body and is also fixedly connected to the upper end of the shock absorber rod. The spring base has a cup-shaped cavity in which is disposed an energy-absorbing block of compressible elastomeric urethane-type material for absorbing energy when the shock absorber system bottoms out by the upper end of the shock-absorbing unit engaging the bottom of the elastomeric block. The energy-absorbing block has a peripheral disc portion extending thereabout and clamped between a dust cover and the spring base for securing the block in position. The energy-absorbing block includes a first plate of non-compressible material disposed between its upper face and the bottom of the cup-shaped cavity in the spring base.

  • Patent number: 4210343
    Abstract: A MacPherson strut type automotive suspension system having an attaching portion to a body of an automobile. This attaching portion includes an inner cylindrical member secured to a piston rod in a shock absorber, an outer cylindrical member disposed in coaxial relation to the inner cylindrical member and secured to the body of an automobile, and a cylindrical resilient member interposed between the both inner and outer cylindrical members.A stopper is secured to the inner cylindrical member and adapted to abut the bottom surface of the cylindrical resilient member, thereby preventing an excessive displacement of the resilient member in its axial direction.

  • Patent number: 4195826
    Abstract: In the illustrated embodiments, an elastomer body has a relatively thin metal layer overlying the elastomer surface to be loaded so as to prevent adhesion at the elastomer surface in spite of a long period of dwell in contact with a relatively more rigid cooperating part such as a hard rubber stop. In a basic form, a thin metal sleeve may encircle a cylindrical elastomer body. The outer surface of the sleeve may be grooved for extra adhesion resistance. In a further development, the sleeve is formed as a helical wire spring which may be confined between two flanges integral with the elastomer body.

  • Patent number: 4011397
    Abstract: Improved multiple mode dampers for damping Aeolian vibrations of electrical cables are provided which employ a single mass and two resilient support members that are respectively connected between separate points of the mass and separate points of the cable. The modes of vibration of the damper are made interdependent by utilizing springs having different moments of stiffness with respect to the center of gravity of the mass. The mass is made of concrete. The improvement comprises the use of springs which are independently connected to the cable at different points permitting the spreading of the springs which can be accomplished economically and yet permit an increase of the rotational torque exerted on the damper by the cable. This facilitates concentration of damper vibration resonance frequencies at critical wind speeds which would ordinarily induce great dynamic mechanical stress in electrical cables.

  • Patent number: 3977700
    Abstract: A tandem axle suspension has a bracket supporting a trunnion on which a pair of beams is journaled rockably in side-by-side relation, each beam having first and second arms extending to opposite sides of the trunnion, the first beam arms projecting in opposite directions and having their distal end portions extending along a common axis and each arranged to receive an axle for a wheel located at one side of the common axis, the first beam arms having respective upwardly facing spring supports which are offset toward the opposite side of the common axis, compression springs carried upon the supports being engaged by downwardly facing thrust structure on the second beam arms. Torsional equilibrium is attained in a vertical plane through the axis of the trunnion and about the common axis of the first arms.

  • Patent number: 3936073
    Abstract: In a friction-free vehicle suspension having axle ends pivotally connected by side walking beams, which are journalled on the ends of a cross rod, the improvement resides in the mounting, arrangement and proportioning of both helical compression springs and rectilinear movement shear rubber springs to support the vehicle frame on the ends of the cross rod. This is done in such manner as to achieve the maximum advantages from the distinctive characteristics of each type. The helical springs, which provide, in a very small space, a very large amount of resilient support, but no lateral control, are located inboard along the cross rod. The shear rubber springs are so mounted outboard along the cross rod to be fully effective in providing adequate resilient control of axle movement both laterally and longitudinally of the line of vehicle movement, as well as vertically, and also to provide high and wide stable spring centers for sidesway control.
