1.2 Travel wheel materials
40Cr
For DRS112~DRS200 models, we utilize 40Cr hot-rolled round steel, meticulously processed through quenching
and tempering treatment to ensure lasting performance.
For DRS250~DRS500 models, we employ 40Cr forgings with tempering treatment, maximizing strength and durability.
This material choice delivers high tensile strength, with comprehensive quenching and
surface quenching treatment, achieving a hardness of HB300-380. Every walking wheel is designed with
a guiding function. When wheel flange guidance is employed, it offers unparalleled precision and reliability.
The precision engineering of our DRS Wheel Box ensures that the gap between the inner surface of the wheel flange and the edge of
the track can be minimized to an astounding 1mm. This same precision level can be achieved by arranging guide wheels, providing
unparalleled consistency. Should there be an anticipated increase in wear, the walking wheel tread or guide wheel rim can be
expertly hardened to HRC56 ± 2 (HB530) to ensure performance without slipping. This hardening process is focused on reducing wear,
extending the lifetime of the walking wheel components. By hardening these elements, we ensure durability and smooth operations,
while the walking wheel's hardening is specifically designed to minimize wear and tear, prolonging its life.
Polyurethane
Polyurethane is a cutting-edge synthetic rubber material that boasts superior
resistance characteristics, setting it apart from other synthetic rubbers with enhanced durability.
When compared with traditional metal materials, polyurethane walking wheels demonstrate
a remarkably higher coefficient of friction, making them the perfect choice for
applications that demand a high dynamic response. The material's exceptional shock
absorption properties significantly reduce walking noise and enhance the user experience.
It's important to note that while polyurethane walking wheels excel in friction and noise reduction,
their load-bearing capacity is somewhat reduced when compared to their metal counterparts.
Due to their low ground contact pressure, polyurethane wheels are exceptionally well-suited for
navigating concrete surfaces. Thanks to the elevated coefficient of friction,
between the polyurethane wheel tread and contact material, these wheels are also ideal for friction-driven
applications that require acceleration up to 1.5m/s2. Furthermore,
polyurethane materials can withstand temperatures up to an impressive
100 degrees Celsius, providing versatile performance across various environments.
Polyurethane's unique properties make it a versatile choice for a wide range of applications.
100 degrees Celsius.
Hardening of Wheels
In situations where running wheels experience significant wear (as evidenced by the presence of iron filings along the track edge),
the metal running wheels can be reinforced by hardening the tread and rim to a depth of 2-3mm. This ensures
continued performance without rim damage for wheels within the DRS112~DRS200 range,
with hardness values reaching HRC56 ± 2 (HB530), demonstrating superior resilience.

Overview
·Flange guide arrangement
For flange-guided wheel blocks, the horizontal force should not surpass 20% of the actual wheel load to ensure optimal functionality.
This limit maintains the structural integrity and performance of the wheel blocks.
·Wheel blocks with roller guide arrangement
For wheel blocks with roller guide arrangements, the horizontal force is capped at 15% of the wheel load, ensuring effective operation.
For DRS112~DRS200 with travel wheel variant E, this percentage is further limited to 12% to maintain optimal performance.
Notably, for DRS200 with a top connection, the permissible force is restricted to 10% to preserve its efficiency.
When anticipating higher horizontal loads, consider fitting the roller guide arrangement to the steel superstructure for added support.
This alternative enables the roller guide arrangement to manage increased loads adeptly, although it should not be directly attached to the wheel block.
For effective load management, the roller guide arrangement should be mounted on the steel superstructure and not on the wheel block itself.
