RAILWAY VEHICLE BRAKING CLAMP Russian patent published in 2015 - IPC B61H1/00 F16D65/06 F16D69/02 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to brake shoes of passenger and freight cars, electrical trains, diesel locomotives, etc. Braking clamp comprises friction element built around polymer composite locked at metal carcass composed by metal strip with reinforcing plate. Weight of metal strip, reinforcing plate and polymer composite is selected processing from the relationship: $$\frac{M_1}{M_2+M_3}=\mathrm{0,29}÷\mathrm{0,45,}$$ where M₁ is metal strip weight, M₂ is polymer composite weight and M₃ is reinforcing plate weight.

EFFECT: enhanced braking performances owing to balanced weight ratio and decreased heat load irregularity.
