Two-axle truck for a railway car and a railway car |
摘要 |
Lateral pressure which develops in the front wheelset when traveling along a curved track is decreased while suppressing an increase in costs as much as possible. A two-axle truck for a railway car has a front wheelset having wheels with a first tread gradient and a rear wheelset having wheels with a second tread gradient which is different from the first tread gradient. The tread gradient of the wheels of the rear wheelset is larger than the tread gradient of the wheels of the front wheelset.
