  • Patent number: 4326607
    Abstract: An anti-rusting structure of an adjust mechanism in a drum brake, which mechanism functions to compensate stroke increasing of the brake system due to wearing of the brake shoes, for preventing production of rust between an adjust bolt and an adjust nut by means of a skillful water proof device by facilitating the greasing between the two members of the adjust mechanism. In a portion of the adjust bolt where external thread (male screw) is formed, at least one lengthwise groove is axially formed, the length of which groove is determined such that the adjust bolt may not be pushed out by compressed air between the two members, even when the adjust bolt is threaded into the adjust nut by a predetermined amount of length, with sufficient grease being spread between the two members.

  • Patent number: 4325468
    Abstract: In a vehicle wherein road wheel travel is controlled by a hydraulic damper hose flow is controlled by a spring-urged metering valve, the improvement wherein the valve spring comprises a helical spring having a constant load-deflection curve and a plurality of coned spring disks having variable load-deflection curves. The preferred suspension for cross-country operation exhibits a relatively hard response to minor bumps, a soft floating response to major bumps, and a comparatively hard snubber-like response to abnormally large bumps. Movement in the rebound direction can be substantially unrestricted, controlled by conventional springs, or controlled by spring stacks similar to those described herein. Conversely, for operation on hard surfaced roads the major control functions could be reversed.

  • Patent number: 4319669
    Abstract: An improved screw type disc brake device particularly adapted for a small type automotive vehicle is disclosed in which a male screw member of a relatively large screw lead is screw-engaged with a caliper arm supporting a movable friction pad so that thrust due to forward rotation of the male screw member is utilized as an urging force to bring the movable friction pad into pressure contact with the brake disc. An automatic gap adjustment device is interposed between the male screw member and the movable friction pad for providing the movable friction pad with an advance feed for every reciprocating rotation of the male screw member. A manual adjustment bolt is screw-engaged through the center of the male screw member for adjusting the position of backward movement of the movable friction pad via the automatic gap adjustment device.

  • Patent number: 4318535
    Abstract: A rear wheel suspension for motorcycles which comprises a hydraulic damper of telescope type consisting of telescopic inner and outer tubes and a suspension coil spring positioned in these tubes. In order to stabilize the damping characteristics, and at the same time, to prevent the inner end cross section of the inner tube from fouling the suspension coil spring and thereby causing unsatisfactory operation, abnormal noise and other problems, one part of the suspension coil spring, which is located in the outer tube under the condition where the hydraulic damper is extended to the maximum, is made smaller in pitch diameter than the other part, which is located in the inner tube so that the inside working oil flow due to its expansion or compression may be hardly hindered by the part of the suspension coil spring that is located in the outer tube.

  • Patent number: 4313526
    Abstract: A disc brake (1) comprises a cylinder (5) slidably mounted on a carrier member (2) for movement parallel to the axis of rotation of the disc. The cylinder (5) is closed at the end adjacent the disc. A bridge member (10) of integral structure, for example forged steel, connects the piston (7) to the outboard brake pad (15). In use, when hydraulic fluid is supplied to the cylinder (5) the cylinder slides on the carrier to apply the inboard brake pad (14) to the disc, and the piston applies a force to the outboard pad (15) via the bridge member (10). The seals (8,9) between the piston (7) and cylinder (5) are isolated from the heat produced by the brake pads, and the bridge member (10) does not require accurate machining and can be designed to provide the maximum strength.

  • Patent number: 4311217
    Abstract: The invention relates to a descent control unit of the kind used for lowering an injured person on a rope. The unit consists essentially of bar around which the rope is wound and a gate arrangement which is hinged to one end of the bar and is detachably secured to the other end of the bar by a locking pin. The bar and gate thus combine to form, in use, a closed loop through which the rope passes. The gate arrangement is formed so as to have a hook which extends beyond the other end of the bar to facilitate a lifting operation using the free end of the rope and a groove is provided in the gate arrangement to guide the free end and facilitate control of the descent rate. A snap hook on the gate provides for connection of the unit to a harness on the injured person and the snap hook is provided with an arm which extends across the groove to retain the rope therein when the unit is under load.

  • Patent number: 4310075
    Abstract: A floating-caliper disc brake (10) includes a non-rotating torque member (38) which carries the caliper (22) in fixed radial position relative to the disc (12) via a pair of pins (50). The torque member and caliper each have matching grooves (46, 48) which, when placed in registry, define a pair of apertures (49) between the caliper and the arms (40, 42) of the torque member. The pins are complementary in cross-section to the shape of these apertures so as to space apart the caliper and the torque member when the pins are inserted into the apertures. Brake torque is transferred from the caliper to the torque member solely through the pins which may be made of a material resistant to corrosion. Sliding of the caliper along the pins provides for axial movement of the caliper relative to the torque member and brake rotor, but the caliper is otherwise restrained from movement in the radial and circumferential directions.
