Title:
CONTROL DEVICE FOR GEARBOX
Document Type and Number:
WIPO Patent Application WO/2023/045706
Kind Code:
A1
Abstract:
Provided in the present invention is a control device for a gearbox, the control device comprising: a sensor module, a differential, a clutch, a brake, and a control module, wherein the control module is configured to actuate, when a system oil pressure is below a system oil pressure threshold, a brake caliper to clamp a brake disc and release the clutch, and is configured to release the brake caliper and close the clutch when the system oil pressure is above the system oil pressure threshold. Different rotation speed ratios of a mechanical pump are obtained by means of combined control of the clutch, the differential and the brake, so that the mechanical pump can have different flows under different operating conditions. Therefore, lubrication requirements of a rated operating condition and a special operating condition are both taken into consideration, and insufficient lubrication under low-speed and/or low-temperature conditions, and excessive oil under the rated operating condition are avoided.
