  • Patent number: 11215254
    Abstract: To provide a vibration control bush that ensures improved durability of a rubber elastic body. An inner pipe film portion of the vibration control has an inclined surface whose inclination angle ? with respect to an axis O direction is set to one degree or more and less than three degrees, and the inner pipe film portion has an end portion in the axis O direction whose thickness dimension is set to a quarter or less of a dimension in an axis O perpendicular direction from an outer peripheral surface of an inner pipe to an apex of the protruding portion. This ensures reducing a rubber elastic body to deform so as to bend (close contact) between the inner pipe film portion and the outer pipe film portion when a load in a wrenching direction is input. Accordingly, a durability of the rubber elastic body can be improved.

    Abstract: The present invention involves a method and system for transmitting two levels of data in a hierarchical transmission schema. A first modulated signal is generated based on first input. A second modulation signal is generated based on a second input that has a data rate that is a fraction of the data rate of the first modulated signal. The second modulation signal has known instances where the second modulation signal has no energy. In a system where the first modulation is quadrature phase shift keying (QPSK), the second modulation signal can be a secondary phase offset. A receiver in the system that has a priori knowledge about the timing relationship between the first data signal and the instances when the second data signal is present will be able to detect both data signals optimally.

  • Patent number: 5897107
    Abstract: A roller bushing assembly (21d, 21e, 21f) designed to enable a low tolerance, frictional fit within an out-of-round or otherwise distorted support member (5, 9) includes a bushing member (29a, 216) having an outer surface (102) machined to provide various axially spaced, annular grooves (127-130, 132 and 242-250). Between or directly adjacent respective ones of the annular grooves (127-130, 132 and 242-250) are defined a plurality of axially spaced and radially extending ribs (113-122 and 232-240). The axial outermost ribs (113, 122 and 240) are preferably elongated relative to the remaining ribs (114-121 and 232-239) and have annularly chamfered portions (124, 125 and 252). The ribs (113-122 and 232-240) are adapted to shear upon mounting of the bushing member (29a, 216) within an out-of-round or otherwise distorted support. By providing the shearable ribs (113-122 and 232-240), the bushing assembly (21d, 21e, 21f) can be effectively mounted within a greater range of varying sized support members.

  • Patent number: 5887881
    Abstract: A suspension system for supporting a frame member on one side of a vehicle chassis on the adjacent end of an axle includes first and second frame brackets, a single-leaf leaf spring, a leaf spring attachment member and a wear plate. The first and second frame brackets are mounted to the frame member on the outer sides thereof. The front end of the single-leaf leaf spring is pivotally connected to the frame member at the first frame bracket and the rear end thereof is connected to the frame member at the second frame bracket. The leaf spring attachment member mounts to the rear end of the leaf spring and connects the leaf spring with the second frame bracket. The leaf spring attachment member includes an arcuate upper surface and a bottom surface. A rebound bolt connects the rear end of the leaf spring and the leaf spring attachment member with the second frame bracket and restricts the movement of the leaf spring to a controlled range.

  • Patent number: 5699865
    Abstract: The invention relates to an antivibration device between a motor unit 2 and a handle unit 9 of a portable handheld motor-driven chain saw 1. The antivibration device includes a sleeve-shaped elastic base body 6 having one of its ends 36 in a receptacle 20 of the motor unit 2 and the other end 46 in a receptacle 90 of the handle unit 9. The ends (36, 46) of the base body are fixed in the receptacles (20, 90) by axially engaging plugs (31, 41) in the end sections (30, 40). The guiding characteristics of the motor-driven chain saw are not affected by base bodies which become damaged or soft. This is so because at least one of the stops 31 has a coupling member 50 which bridges an axial spacing (z) between the plugs (31, 41) and projects into the other plug 41 and is latched so that it cannot be axially separated therefrom. A mechanical connection remains between the handle unit and the motor unit when the base body tears off.

  • Patent number: 5560590
    Abstract: A vehicle suspension friction control assembly includes vehicle suspension having at least two elements which are slidable with respect to each other in the fore-and-aft direction thereof. The assembly also includes a friction control device comprising a resiliently deformable member which is located between the suspension elements and means for limiting deformation of the deformable member to a predetermined degree in the fore-and-aft direction of the suspension elements. The suspension elements are slidable with respect to each other against friction when the deformable member has been deformed to the predetermined limited degree.

  • Patent number: 5542652
    Abstract: An anti-friction pad for a bushed pivot connection of a main leaf spring and a secondary leaf spring of a spring mounted air spring suspension of a vehicle. The pivot connection includes a bushing, a main leaf spring having an eye receiving the bushing and a secondary leaf spring having an eye receiving the eye of the main leaf spring and the inside surfaces of bushing hanger bracket. The anti-friction pad has an elongated main body portion positioned between and in contact with the main leaf spring and the secondary leaf spring. The anti-friction pad also has side walls which engage the secondary leaf spring. The anti-friction pad has a center post which seats in a socket of the secondary leaf spring. The main body portion of the pad has an outer convex surface which mates with a concave face of the main leaf spring. The anti-friction pad is formed of an ultra high molecular weight polyethylene.

  • Patent number: 5020824
    Abstract: A suspension for a vehicle having tandem axles includes a composite leaf spring connected between the axles. The leaf spring is constrained to bend about a transverse axis by a fixed elastic support having a concave, arcuate bottom surface whose center coincides with the transverse axis. The elastic support engages the top surface of the leaf spring at two points on opposite sides of the transverse axis, and is opposed by a central elastic element. The ends of the leaf spring are connected to the tandem axles by ball joints having elastic pads.

  • Patent number: 4768807
    Abstract: A motor vehicle wheel suspension has a composite leaf spring arranged transversely supporting a wheel support. A pivot retainer and tuneable rubber bushing arrangement supports the spring on the vehicle frame so that the spring is positively retained thereon while elastically supported with a tuneable fore/aft, vertical and lateral compliance and while also being pivotal about an axis intersecting at right angles with the neutral shear plane of the spring.
