Track working or transport vehicle
First Claim
1. A track working or transport vehicle comprising(a) a frame,(b) two spaced apart undercarriages supporting the frame, each one of the undercarriages having a respective side frame associated with a respective one of the track rails, an axle supported on the side frames and a respective wheel mounted on the axle and running on the respective track rail,(c) spring means mounted between the side frames of the undercarriages and the frame of the vehicle, each of the spring means having a stroke whose length corresponds directly to variable loads distributed to a respective one of the wheels from the frame,(d) a displacement pickup connected to each one of the spring means and arranged to measure the stroke of the spring means connected thereto, the pickup generating an electrical output signal corresponding directly to the measured stroke, and(e) an arrangement for continuously monitoring and indicating the loads distributed to the respective wheels, the arrangement including(1) a summation circuit having a first input receiving the output signals from the pickups, a second input receiving fixed electric signals corresponding to the weight of non-yieldingly mounted parts of the undercarriages, and an output transmitting electrical output signals corresponding directly to the wheel loads derived from the inputs, and(2) an indicator device receiving each output signal from the summation circuit and correspondingly indicating the wheel loads.

Abstract
A track working or transport vehicle comprises a frame and two undercarriages supporting the frame. Springs are mounted between the side frames of the undercarriages and the vehicle frame, the springs having a stroke whose length is proportional to variable loads distributed to a respective undercarriage wheel from the vehicle frame. A displacement pickup is connected to each group of springs and arranged to measure the stroke thereof, the pickup generating an electrical output signal proportional to the measured stroke. An arrangement for continuously monitoring and indicating the loads distributed to the respective wheels includes a summation circuit having a first input receiving the output signals from the pickups, a second input received fixed electrical signals proportional to the weight of non-yieldingly mounted parts of the undercarriages, and an output transmitting electrical output signals proportional to the wheel loads derived from the inputs. An indicator device receives each output signal from the summation circuit and correspondingly indicates the wheel loads.
