Bogie - Wikipedia
Radial-steering trucks, also known as radial bogies, allow the individual axles to align with curves in addition to the bogie frame as a whole pivoting. For non-radial bogies, the more axles in the assembly, the more difficulty it has negotiating curves, due to wheel flange to rail friction.

2020年4月5日 · EMD recognized that radial steering trucks on locomotives could be very beneficial with advantages of: -Reduce wheel squeal in curves. In the late 1970's EMD started seriously studying radial trucks beginning with literature study and the creation of math models to evaluate truck curving and adhesion performance.

2024年12月19日 · The radial trucks do their job in extending wheel life by reducing flange wear so the condemning wheel condition is changed from thin flange to high flange generally. The longer wheel life leads to more hollowing of the tread which increases the effective conicity of the wheel to rail which does lower the speed for truck hunting.

2008年7月15日 · Radial is where the axles in the truck are always perpendicular to the rail, or parallel with the curve’s radius, if you prefer… Conventional trucks keep the axles always perpendicular to the truck frame so the don’t align exactly with the rail in curves. Here’s a picture:
radial axle trucks compared with 152,000 miles for standard trucks—an improvement of more than 20 percent. This substantial drop in wheel removals for radial trucks demonstrates the effec-tiveness of the radial action in reducing wheel flange contact with the rail during operation and thus decreasing wear.

1939 Plymouth Air Radial Truck - Roadkill Customs
2018年3月20日 · Colorado Auto & Parts is home to the famous “Plymouth Air Radial Truck” — A 1939 Plymouth PT-81 truck with a seven-cylinder, air-cooled, radial engine from a 1954 Cessna 195 Airplane. The project for the radial-engined truck began years ago when Gary Corns bought the beat-up old 1939 Plymouth from a regular customer.
