摘要： A system is provided for use with, a wheeled vehicle. The system includes a media reservoir capable of holding a tractive material that includes particulates; a nozzle in fluid communication with the media reservoir; and a media valve in fluid communication with the media reservoir and the nozzle. The media valve is controllable between a first state in which the tractive material flows through the media valve and to the nozzle, and a second state in which the tractive material is prevented from flowing to the nozzle. In the first state, the nozzle receives the tractive material from the media reservoir and directs the tractive material to a contact surface such that the tractive material impacts the contact surface that is spaced from a wheel/surface interface. The system can modify the adhesion or the traction capability of the contact surface with regard to a subsequently contacting wheel.

摘要： Methods and system are provided for a vehicle truck assembly which includes a spring coupling an axle carrier to a truck frame. In one example, the system comprises a substantially vertically-mounted hydraulic actuator which generates hydraulic forces between the axle carrier and the truck frame. The actuator includes a cylinder, a piston, and a piston rod. Further, the actuator is coupled between the axle carrier and the truck frame with longitudinal and lateral play so that the axle carrier can move laterally and longitudinally with respect to the truck frame while the actuator applies hydraulic force.

摘要： A system and method for modification of a baseline ballast arrangement of a locomotive (or other rail vehicle) having an overall tractive effort rating based on symmetrical distribution of weight and driving torque applied by the locomotive to the respective axles of the locomotive. The system includes a locomotive (or other rail vehicle) truck comprising an un-powered first axle and a powered second axle. The system also includes a first suspension assembly configured to apply to the first axle a first portion of a locomotive weight and a second suspension assembly configured to apply to the second axle a second portion of the locomotive weight different from the first portion. An amount of locomotive weight allocated from the first axle to the second axle allows modification of a baseline ballast arrangement by reducing an amount of ballast in the baseline ballast arrangement corresponding to the amount of weight allocated from the first axle to the second axle. The axle weight distribution involves relatively slight weight distribution compared to the nominal weights normally carried by the axles.
