MULTI-MODE ELECTRICALLY CONTROLLED STEERING HYDRAULIC SYSTEM AND LOCOMOTIVE DEVICE

WIPO Patent Application WO/2020/199526

A1

Discloses are a multi-mode electrically controlled steering hydraulic system (100) and a locomotive device (200). The multi-mode electrically controlled steering hydraulic system (100) has a front axle steering mode, a rear axle steering mode, a splayed steering mode and a diagonal traveling mode. When the multi-mode electrically controlled steering hydraulic system (100) is in the front axle steering mode, the rear axle steering mode, the splayed steering mode and the diagonal traveling mode, the rotation angles of wheels (201) of a locomotive device (200) using the multi-mode electrically controlled steering system match each other; and when the multi-mode electrically controlled steering hydraulic system (100) is in the diagonal traveling mode, the rotation angles of the wheels (201) of the locomotive device (200) are consistent, thereby preventing non-pure rolling of some of the wheels (201), such that the steering resistance moment of the locomotive device (200) is reduced, the traveling resistance is reduced, and correspondingly, the energy consumption of the locomotive device is also reduced.
