摘要:
The specification discloses an improved railway car truck providing increased dampening for high volume rail cars by the use of bolster pocket wear plates in combination with five different types of springs in the spring baskets of the railway car trucks. The five different types of springs include either a single outer coil, or inner and outer coaxial coils, with the outer coils being of different lengths to provide multiple effective spring rates action which place the critical frequency of the car trucks at two different speeds, rather than a single speed, and makes the amplitude of resonance occurring at the critical frequency much smaller than would otherwise occur, to prevent the car truck from resonating in such a way as to rock the rail car excessively. These types of spring arrangements also prevent excessive vertical bouncing of railway cars.
