Abstract

The invention discloses a hydraulic control device for a hybrid power transmission, wherein a main oil-way is respectively connected with a lubricating oil-way, a clutch control oil-way and an electromagnetic valve control oil-way, the main oil-way is connected with a cooling and lubricating oil-way through an unloading valve, the cooling and lubrication oil-way is connected with a valve core control oil port of the unloading valve at the same time, the oil outlet of the unloading valve is respectively connected with an oil inlet of an overflow valve and the clutch control oil-way, the oil outlet of the overflow valve is connected with the lubricating oil-way, the clutch control oil-way is respectively connected with oil inlets of proportional reducing valves A and B, a reducing valve is arranged between the electromagnetic valve control oil-way and the main oil-way, the electromagnetic valve control oil-way is respectively connected with valve core control oil ports of the proportional reducing valves A and B through oil-saving holes, and is respectively connected with a switching electromagnetic valve and a halt locking hydraulic cylinder through the oil-saving holes. The hydraulic control device has simple structure, can rapidly lubricate the transmission, and is suitable for the hydraulic control of the hybrid power transmission.

Description

technical field [0001] The invention relates to a vehicle hydraulic control device, in particular to a hydraulic control device for a hybrid transmission of a hybrid vehicle. Background technique [0002] Due to the shortage of energy and the enhancement of public awareness of environmental protection, environmentally friendly electric vehicles or fuel cell vehicles have emerged as the times require. Power vehicles are an ideal choice at present. [0003] Since the transmission of a hybrid vehicle mostly uses a planetary gear transmission mechanism, such as figure 1 The hybrid transmission of Toyota's hybrid vehicle Prius shown in the figure can realize continuously variable transmission, so the hydraulic control device mainly used for gear shift control is generally not provided in the transmission as in the automatic transmission. In order to improve the transmission efficiency of the transmission, it is necessary to set a lock-up clutch in the hybrid transmission, so th...
