  • Patent number: 10774894
    Abstract: A damping valve for a hydraulic damper comprises a valve housing comprising an inlet chamber and an outlet chamber. A valve seat is arranged between the inlet chamber and the outlet chamber. A valve element having a cylindrical first portion is slidably received in a cylindrical bore of the valve housing.

  • Patent number: 10766470
    Abstract: This brake control device includes: an operation amount sensor which detects the brake operating member operation amount; front-wheel and rear-wheel actuators which generate braking force in front/rear wheels; front-wheel and rear-wheel sensors which detect the outputs of the front-wheel and rear-wheel actuators; and a controller which controls the front-wheel and rear-wheel actuators based on the operation amount and the outputs of the front and rear wheels. On the basis of the operation amount and/or the output of the rear wheels, the controller determines whether or not a long-term low-load state in which the friction member is continuously pressed against the rotary members of the rear wheels within a predetermined range over a long period of time is established. If so, the distribution ratio of the rear-wheel braking force to the total applied braking force is decreased compared to when a long-term low-load state is not determined to be established.

  • Patent number: 10704635
    Abstract: A spring assembly is provided which decreases the fatigue and wear on the springs of the assembly. The spring assembly includes upper and lower pistons separated by a substantially incompressible fluid. The lower piston is attached to one or more springs. The surface area of the upper surface of the lower piston is greater than the surface area of the lower surface of the upper piston. As such, the springs are deflected by a distance less than the distance traveled by the upper piston. By decreasing the length the springs are compressed, the springs are subject to less fatigue and wear. As a result, the life span of the springs is increased and the maintenance required of the spring assembly is minimized relative to that of typical spring assemblies.

  • Patent number: 10682970
    Abstract: A shock absorption device includes an inner cylinder assembly threadably engaged within an outer cylinder assembly. The outer cylinder assembly includes a cap shaped member, at least one protruding member, and at least one first spring member. The inner cylinder assembly includes at least one compressive member, at least one second spring member, and at least one movable piston member. When an external impact force is applied to the cap shaped body member, the first threaded portion of the outer cylinder assembly jumps over the second threaded portion of the inner cylinder assembly as provided by elastic movement of the resilient ring member about the cap shaped body member. The thread jumping results in the first spring member compressing and the protruding member pushing the piston member which pushes and compresses the second spring member and the compressive member providing a reactive force to absorb the external impact force.
