Abstract
The utility model relates to a gear shifting oil line for an automatic transmission. The gear shifting oil line for the automatic transmission comprises an oil pump, a hydraulic torque converter control valve, a hydraulic torque converter, five gear shifting control valves and a counterbalance valve. A first oil inlet of the hydraulic torque converter control valve is communicated with the oil pump; a first oil outlet of the hydraulic torque converter control valve is connected with an oil inlet of the hydraulic torque converter; an oil outlet of the hydraulic torque converter is connected with a second oil inlet of the hydraulic torque converter control valve; a second oil outlet of the hydraulic torque converter control valve is respectively connected with oil inlets of the five gear shifting control valves; and drainage ports of the five gear shifting control valves are communicated with the inlet of the counterbalance valve. As oil pressure exists in the five gear shifting control valves in the gear shifting oil line all along, the oil charge time is shortened when gear shifting is performed, and the gear shifting response time is high. Meanwhile, when the oil pressure in the pipeline is higher than a set value, the counterbalance valve starts draining, and the oil pressure in the pipeline is kept to be at the set value, and thereby, the pressure in the oil line is stable, the gear shifting impact is reduced, and the gear shifting stability is improved.
