Wheelset Solutions for Rail & Industrial Equipment: Specs, Features & Customization for Efficiency & Durability

Overview of Wheelset

Wheelset is the core power transmission component of rail transit vehicles (subways, trains, trams) and some industrial equipment (mining trucks, port cranes, heavy forklifts). It is composed of two wheels + an axle and is permanently assembled through interference fit or hot-fitting process. It undertakes the following key functions:

Support load: bear the entire weight of the vehicle/equipment (such as subway wheelsets need to carry 15-30 tons/axle)
Transmit power: convert traction motor or engine torque into linear motion
Guide driving: control the running direction through the contact between the wheel flange and the track/ground
Absorb shock: buffer the vibration caused by uneven track or complex terrain
Analogy: The wheelset is equivalent to the “two legs + joints” of a car, which must support the weight (load), achieve walking (transmission), and maintain balance (guidance).

Specification of Wheelset

Features of Wheelset

1.Core structure

Wheel body design: Double S-shaped tread geometry, similar to “tire pattern optimization”, disperses contact pressure and reduces wear
Bearing system: High-precision double-row tapered roller bearings, similar to “car shock absorbers”, reduces vibration and starting torque
Sealing solution: Triple labyrinth seal, similar to “waterproof watches”, isolates dust and water vapor

2.Performance breakthrough

Lightweight: Topologically optimized rim structure, similar to “honeycomb structure”, reduces weight by 12%, reduces equipment energy consumption
Impact resistance: The rounded transition design at the root of the rim is similar to “car anti-collision beam”, and has passed 500,000 fatigue impact tests
Temperature resistance: -35℃ low temperature toughness, similar to “polar equipment”; +75℃ high temperature stability, similar to “desert engine”

3.Customization capability

Size compatibility: supports full range customization of wheel diameters of 400-1000mm and axle necks of Φ80-Φ220mm, suitable for “equipment of different sizes”
Surface treatment: optional galvanizing + Dacromet double coating (salt spray test ≥800h) or ceramic composite coating, similar to “rust-proof armor”

Application of Wheelset

1.Core functions

Intelligent wear reduction: The tread is pre-set with an elastic deformation layer, similar to the “tire shock absorption technology”, which reduces the wheel-rail contact stress by 30%

Thermal management: The internal guide groove design of the wheel hub is similar to the “automobile cooling system”, and the bearing temperature rise is ≤60℃ during continuous braking

Monitoring compatibility: reserved sensor installation position, support for wireless data transmission, similar to the “equipment intelligent physical examination interface”

2.Industry adaptation

Railway transportation:
Metro wheelset: low-noise pattern design, similar to “silent tires”, noise ≤85dB when passing through turnouts
Freight wheelset: bimetal rim structure, similar to “anti-skid tires”, anti-peeling performance increased by 50%
Mining machinery:
Wide-base wheelset (wheelbase ≥1600mm): similar to “wide off-road vehicle tires”, lateral stability increased by 40%
Explosion-proof wheelset: special surface treatment, similar to “explosion-proof mobile phone coating”, passed extreme environment simulation test
Port equipment:
Salt spray-proof wheelset: Dacromet + graphene composite coating, similar to “marine equipment anti-rust layer”, MTBF ≥1800 hours
Heavy-duty wheelset: axle neck reinforcement design, similar to “truck heavy-duty chassis”, load capacity up to 120 tons/axle
