Title:

ZERO-STEERING HYDRAULIC DRIVE AXLE

Document Type and Number:

WIPO Patent Application WO/2023/160129

Kind Code:

A1

Abstract:

A zero-steering hydraulic drive axle, comprising: a housing (1), wherein a first drive assembly (201) is arranged in the housing (1); one end of the first drive assembly (201) is connected to an external power input device for power input, and the other end of the first drive assembly (201) is connected to an external rotary output device for power output; the first drive assembly (201) comprises a plunger pump (301) and a plunger motor (302); one end of the plunger pump (301) matches the power input device to achieve active rotation of the plunger pump (301), and the other end of the plunger pump (301) is connected to an external oil pipe for oil feeding or oil supplementation; the plunger motor (302) matches the rotary output device; and the plunge pump (301) and the plunger motor (302) are in communication with each other by means of an oil circuit to achieve power transmission from the plunger pump (301) to the plunger motor (302). The zero-steering hydraulic drive axle has a simple overall structure and a stable power output, can achieve stepless speed change and in-situ steering and turning, and has a wider application scene range.
