Document Type and Number:
WIPO Patent Application WO/2023/231227
Kind Code:
A1
Abstract:
Provided are a power system and an electric wheel device. The power system comprises a frame (1), electric wheels (2) and generator sets (3), wherein the electric wheels (2) are mounted on two sides of the frame (1); the width of a front end of the frame (1) is greater than the width of a rear end thereof; two generator sets (3) are provided at the front end of the frame (1), and the two generator sets (3) are arranged in parallel on an inner side of the frame (1); another generator set (3) is also provided on the inner side of the frame (1) and behind the two generator sets (3); and each generator set (3) is electrically connected to the electric wheels (2) and can supply power to the electric wheels (2). The three generator sets (3) having a low power are used to replace a high-power generator set, which improves the universality of parts of the generator sets and reduces the purchase cost of the parts, thereby also reducing the maintenance cost of an electric-wheel mine car. The generator sets are mounted on the basis of the feature that the frame is wide at the front and narrow at the rear, so that the structural space of the frame is fully utilized, the power system is enabled to be more compact without increasing the width of the whole vehicle, and the passage performance of the electric-wheel mine car is then ensured.
