Abstract

A hydraulic control oil circuit of an automatic transmission with an electronic gear shifting function belongs to the technical field of hydraulic control oil circuits of transmissions. The invention aims to solve the problems of long shifting time, slow shift response and poor fuel saving ability of traditional transmission hydraulic oil circuits. Including mechanical oil pump, main pressure regulating valve, pressure limiting valve, TC regulating valve, cooler bypass valve, DCC valve, parking logic valve, start-stop control valve, limp selection valve, on-off valve, shift safety valve A, shift Safety valve B, oil supply spool, solenoid valve SL, solenoid valve SLTC, solenoid valve SLC1, solenoid valve SLC2, solenoid valve SLC3, solenoid valve SLC4, solenoid valve SLB1, solenoid valve SLB2, solenoid valve S1, solenoid valve S2, solenoid valve Valve S3, solenoid valve S4, solenoid valve S5 and start-stop plunger pump. The hydraulic control oil circuit of the automatic transmission with electronic shifting function of the present invention does not need to supply oil through the on-off of the on-off valve and the switching of the mechanical valve core, thereby greatly shortening the shifting time and improving the responsiveness of shifting.

Description

technical field [0001] The invention relates to a control oil circuit, in particular to a hydraulic control oil circuit of an automatic transmission with an electronic shift function, and belongs to the technical field of transmission hydraulic control oil circuits. Background technique [0002] New energy vehicle technology has undoubtedly become one of the important technologies to solve global energy and environmental problems, and my country, as a big automobile consumer, faces more challenges and the urgency of technological innovation. In a long time, various forms of hybrid technology will be an important transition route. According to whether the technology is upgraded based on traditional power, hybrid technology can be divided into P-structure hybrid and power-split hybrid. The power-split hybrid is a newly developed special electric drive transmission for hybrids. It has obvious advantages in cost, layout space, efficiency and fuel-saving capabilities. It is wide...
