Structural Mechanics Overview
1. Robust Chassis & Cab Assembly
The primary structure features a heavy box-type frame skillfully welded from premium steel plates. Internal partition plates effectively divide the chassis into three functionally optimized compartments: the forward operator cab (integrated seamlessly with a rigid protective roof containing controllers and operational gear), the central mechanical room housing the motors, sandboxes, and brake links, and the rear compartment enclosing the ballast weights.
2. Powertrain & Driving Mechanics
Propulsion is generated by twin flameproof motors paired with single-stage reduction gearboxes featuring i=6.92 gear ratios (Large gear: Z=90 m=6; Small gear: Z=13 m=6). The driving assembly leverages splash lubrication and maintains an 8kg gear oil capacity inside the transmission case for reliable long-term service.
3. Mechanical Brake & Sanding Mechanisms
Safety deceleration relies entirely on an advanced 4-wheel mechanical brake assembly utilizing brake shoes, balancing arms, heavy-duty screws, and a manual driver handwheel to trigger immediate, unified friction contact. To manage wheel slip under wet conditions, a mechanical pull-rod sanding system applies sand from specialized reservoirs directly to the rail-wheel contact point, immediately optimizing the adhesion coefficient.
Frequently Asked Questions (FAQ)
What track gauges does the CBY8 8-ton mining locomotive support?
The CBY8 locomotive is highly versatile and compatible with standard mining track gauges of 600mm, 762mm, and 900mm.
What are the permissible ambient environmental conditions for operation?
This locomotive is designed to operate safely under the following underground conditions: altitudes not exceeding 2000 meters, ambient temperatures ranging between -20°C and +40°C, and a maximum relative humidity of 95% (with the average lowest temperature of that month not exceeding 25°C).
What is the maximum travel speed and peak tractive effort?
The CBY8 8-ton locomotive delivers a maximum operational speed of 12 km/h and can reach a peak maximum tractive effort of 19.62 kN. Its hourly rated speed is 7.8 km/h with an hourly tractive effort of 12.83 kN.
What specific lithium battery and motor models are pre-installed?
It is equipped with one DXBL32384/140.8C(A) explosion-proof lithium-ion battery power supply unit and two ZBQ-15 flameproof DC traction motors operating at a rated voltage of 140V.
How does the mechanical braking system function on this vehicle?
The braking system is completely mechanical, composed of brake shoes, connecting levers, a balancing arm, and a control handwheel linked to a screw rod. Turning the handwheel clockwise simultaneously clamps four single-direction brake shoes against all four wheels for highly stable stopping power.
What type of gear transmission and lubrication system does it use?
The locomotive uses a single-stage reduction gearbox with a gear ratio of i=6.92 (90-tooth large gear and 13-tooth small gear, modulus m=6). The gearbox employs a splash lubrication method and requires 8kg of standard universal gear oil.
