Bangladesh brake shoes

  • Bangladesh brake shoes

Detailed Introduction

Product model:MJLHCZW-I

The Bangladesh brake shoes are designed specifically for railway vehicles in Bangladesh,such as meter gauge passenger cars and freight trains.They are made of high-quality synthetic or cast iron materials and are suitable for braking needs in tropical humid weather conditions.This product has the characteristics of wear resistance,moisture and corrosion resistance,and smooth braking,and is suitable for various braking systems.

2.Core technical features

High friction stability

Composite brake shoe:friction coefficientμ=0-10-0.35(adjustable,in accordance with BS 5892 standard)

Cast iron brake shoes:friction coefficientμ=0.15~0.25(high phosphorus cast iron,excellent wear resistance)

Good wear resistance

Composite brake shoe wear rate≤0.15 cm3/MJ(30%longer than traditional cast iron brake shoes)

Suitable for frequent braking conditions(such as urban commuter trains)

Environmental adaptability

Moisture and rust prevention(suitable for rainy climate in Bangladesh)

Non asbestos(compliant with international environmental regulations)

lightweight design

The weight of synthetic brake shoes is reduced by 40%compared to cast iron brake shoes,resulting in a decrease in unsprung mass

3.Materials and Structure

(1)Synthetic brake shoe

Ingredient ratio function

Phenolic resin 20-30%high temperature resistant matrix

10-15%aramid fiber enhances shear resistance

Graphite 5-10%adjusts friction coefficient

Aluminum oxide 15-20%improves wear resistance

(2)Cast iron brake shoes

High phosphorus cast iron(phosphorus content≥0.7%)

Alloy strengthening(chromium and molybdenum elements increase hardness)

Structure Design

Heat dissipation groove:Optimize groove layout to improve heat dissipation efficiency

Wear alarm:mechanical indicator(triggered by remaining 5mm)

4.Suitable vehicle models

Meter gauge(1000mm)trains:Bangladesh Railway passenger and freight cars

Standard gauge(1435mm)vehicles:Some modern high-speed trains

5.Maintenance requirements

Inspection cycle:Every 20000 kilometers or 6 months

Replacement standard:

Composite brake shoe thickness≤5mm

Cast iron brake shoe thickness≤10mm

Installation precautions:

Clean the brake drum/wheel hub contact surface

Check the gap between the brake shoe and the brake surface(1-2mm)
