The utility model
Principle of workAs follows:
1. halting mechanism separates
When car started, driving engine can drive oil pump and rotate, and this moment, oil pump began fuel feeding; Because electromagnetic valve is a precision element, the cleanliness level demand is higher, need filter with fil; The maximum pressure of by pass valve major limitation oil circuit makes the pressure in the system can not surpass system's maximum constraints.
Automatic transmission with hydraulic torque converter original system oil circuit comprises cooling oil circuit, channel for oiling, power-transfer clutch/tor-con control oil channel, actr oil circuit etc.
The two-bit triplet electromagnetic valve is in closed condition oil impassabitity when not switching on, begin logical oil for this moment the energising of two-bit triplet electromagnetic valve; The 2/2-way electromagnetic valve is in closed condition when beginning; This moment, energising back oil arrived the promotion piston push rod of hydraulic actuating cylinder through it, and the power that overcomes pull back spring promotes to the park pawl direction, drives park pawl and rotates around its locating dowel pin; Park pawl is separated with the Parking gear, realize that Parking separates.
Pressure sensor is used to monitor the pressure of hydraulic actuating cylinder, closed electromagnetic valve when reaching specified pressure; When owing to reveal pressure decay to certain index, after opening the 2/2-way electromagnetic valve and carrying out fuel feeding, close then, keep the hydraulic actuating cylinder oil pressure always at specified pressure.
Energy storage carries out pressure compensation under the situation that hydraulic actuating cylinder is revealed, it is constant to keep-up pressure.
2. halting mechanism locking
When car stopped, this moment, driving engine stopped operating, oil pump this moment stop control lever.
The two-bit triplet electromagnetic valve is in closed condition when not switching on, give the energising of 2/2-way electromagnetic valve, and under the effect of pull back spring, the oil in the hydraulic actuating cylinder is got back to fuel tank through the two-bit triplet electromagnetic valve then through the 2/2-way electromagnetic valve; The 2/2-way closed electromagnetic valve.
Because piston push rod links to each other with park pawl, therefore get back to original position when piston push rod, drive ratchet and rotate around its locating dowel pin.Under the effect of pull back spring, make park pawl and Parking gear mesh, realize parking lock.
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art, the technological advance of being obtained is: the utility model is on original control oil channel of existing automatic transmission with hydraulic torque converter, an oil circuit of increase; Control halting mechanism, reduce component count; Having adopted the two-bit triplet electromagnetic valve advanced makes the oil in the hydraulic actuating cylinder let out sooner; Adopt the simplest two electromagnetic valves, the break-make of control oil channel is controlled more accurate; No oil pressure in the hydraulic actuating cylinder is realized parking lock during Parking, under long-time Parking situation, does not worry the leakage problem of hydraulic actuating cylinder.
The utility model is applicable to various automatic transmission with hydraulic torque converters, is connected between original control oil channel and the park pawl, realizes the hydraulic control Parking.
