Document Type and Number:
WIPO Patent Application WO/2020/215598
Kind Code:
A1
Abstract:
A steering and braking hydraulic pump assembly (60), applied to an unmanned vehicle (1). The steering and braking hydraulic pump assembly (60) comprises: a hydraulic pump (61), a motor (621), a brake valve group (632), a steering valve group (631), and a pump assembly controller (65). The hydraulic pump (61), the brake valve group (632), and the steering valve group (631) are controllably connected to the pump assembly controller (65) separately. The pump assembly controller (65) is configured to receive control instructions and convert same into electrical signals. The pump assembly controller (65) controls the motor (621), the hydraulic pump (61), the brake valve group (632), and the steering valve group (631) on the basis of the electrical signals. The hydraulic pump (61) pumps pressure oil toward the brake valve group (632) and the steering valve group (631) under the control of the pump assembly controller (65). Also provided are an unmanned vehicle (1) having the steering and braking hydraulic pump assembly (60) and a working method of the steering and braking hydraulic pump assembly (60).
