Integrated wheel of broad-track internal combustion locomotive

Abstract

The invention discloses an integrated wheel of a broad-track internal combustion locomotive. The integrated wheel comprises a wheel hub, a wheel rim and a wheel disk for connecting the wheel hub with the wheel rim, wherein the diameter of the outer edge of the wheel rim contacting a track is 1080-1083 mm; the thickness of the wheel rim is 74.5-77 mm; and the width of the wheel rim is 140-143 mm. According to the integrated wheel, the diameter of the outer edge of the wheel rim contacting the track meets the bottom limitation requirement of the broad-track internal combustion locomotive, the thickness of the wheel rim guarantees the all-wear size range of the wheel, and the width of the wheel rim guarantees the normal contact of the wheel and the track, so that the broad-track internal combustion locomotive runs safely on the track.

Description

technical field [0001] The invention relates to diesel locomotive technology, in particular to an integral wheel of a wide-gauge diesel locomotive. Background technique [0002] The wheel is one of the key parts of the wheel set. However, the wheel set is also an important part directly related to the driving safety of the running part of the locomotive and bears huge static loads and dynamic loads. On the one hand, the entire weight of the locomotive is finally supported on the rails through the wheels; on the other hand, all the traction and braking forces of the locomotive are ultimately derived from the friction between the rails and the wheel tread; moreover, the locomotive must always be along the rails To travel, the rim of the wheel must play its guiding and protective functions, and the wheel set rotates to realize the running of the locomotive on the rail. At present, the diameters (referring to the outer edge diameter of the rim contacting the track) commonly use...

Problems solved by technology

However, for countries that use wide-gauge (1520mm rail spacing), due to the difference between the wide-gauge line boundary and the quasi-gauge (1435mm rail spacing) line boundary, and the influence of other factors such as the traction motor suspension system, the locomotive wheels installed on the axle A certain distance must be maintained between the lower end of the component and the contact surface of the track and the wheel to ensure the safety of the locomotive during driving. This distance is called the bottom limit of the locomotive. The use of Φ1050mm wheels cannot meet the bottom limit requirements of wide-gauge locomotives
