  • Patent number: 10570983
    Abstract: A damper system for a vehicle is provided that includes a pressure tube and a piston assembly separating the pressure tube into first and second working chambers. A frequency dependent damper assembly, coupled to a piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a first valve assembly mounted to the piston assembly. The frequency dependent damper assembly includes first and second accumulation chambers that are separated by a floating piston. A second valve assembly, carried on the floating piston, controls fluid flow between the second accumulation chamber and the second working chamber. A bleed channel in the floating piston allows fluid flow between the first and second accumulation chambers, which reduces the adaptive force the plunger sleeve applies to the first valve assembly during high frequency, low velocity rebound inputs.

  • Patent number: 10501098
    Abstract: A railway vehicle parking brake that can provide the appropriate tension to the braking system using a motor, a brake chain drum interconnected to the motor to take up or release a brake chain, a load arm deflects in response to tension in the brake chain, and a switch that is closed by the load arm when it deflects. A movable sheave interconnects the brake chain and the load arm and is positioned between the brake chain drum and a fixed sheave over which the brake chain is looped. A control method considers the position of the first switch to determine whether to the motor off when applying the brakes and the amount of current being drawn by the motor to determine whether to the motor off because of a system failure.

  • Patent number: 10493969
    Abstract: A brake assist system comprising an intermediate spring combined with a compression thrust bearing, limiting the compression to a force greater than the response of the brake pedal under normal operating conditions. The spring and its compression thrust bearing are placed between the plunger piston (2) and the helper piston so that the spring transmits the thrust from the helper piston to the plunger piston that pulls the pedal under normal braking conditions. The helper piston pushes the plunger piston by way of the compression thrust bearing when the response of the plunger piston exceeds the compression threshold. A contact detector detects the contact between the helper piston and the thrust bearing.
