Multi-rate vertical load support for an outboard bearing railway truck |
摘要 |
A constant-contact load-bearing assembly for a railcar truck bolster and operable against a complementary body bolster bearing and biased to continuously contact the body-bolster bearing to transfer the lading and railcar weight forces, which assembly has an outer element of a first coefficient of friction, a second or inner element with a second and larger coefficient of friction and biasing apparatus to maintain the inner assembly pad element in contact with the body-bolster assembly at an empty-railcar condition to provide control of the railcar body at the empty or unloaded car status with the biasing apparatus compressible at a loaded railcar state to provide contact between the outer pad element and the body-bolster bearing pad for transfer of the railcar loads and forces over the range of operating loads between the empty-car state and the loaded to capacity state.
