Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the hydraulic schematic diagram of torque converter control system of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Consult shown in Fig. 1, torque converter control system of the present invention, comprise oil feed pump 1, also comprise the principal pressure modulating valve 6 and pilot pressure modulating valve 5 that are connected with oil feed pump 1, principal pressure modulating valve 6 is for regulating system operating oil pressure, reach suitable operating range, pilot pressure modulating valve 5 is for reducing pressure to principal pressure, and the normally closed pilot proportional solenoid valve 12 with first respectively, often drive pilot proportional solenoid valve 13 for two, three the second normally closed pilot proportional solenoid valves 14, holotype control valve 7 is connected with switch electromagnetic valve 15, wherein, first normally closed pilot proportional solenoid valve 12 is connected with lock-up clutch 16, often drive pilot proportional solenoid valve 13 for two, three the second normally closed pilot proportional solenoid valves 14, switch electromagnetic valve 15 is through first, the how logical hydraulic control valve (8 of second multidigit, 9) be respectively connected with six clutches 20, pressure oil is through first, the how logical hydraulic control valve (8 of second multidigit, 9) reasonable distribution, finally realize the combination of six clutches 20 or separation thus obtain seven advance gears of torque converter, a neutral and a reverse gear.In the present invention, export control command by ECU, power to the first normally closed pilot proportional solenoid valve 12, pressure oil enters lock-up clutch 16, realizes the work of torque converter locking operating mode.If do not power to the first normally closed pilot proportional solenoid valve 12, torque converter works under bending moment operating mode.The outlet port of oil feed pump 1 is also connected with a safety valve 4, and safety valve 4, for the maximum pressure of restriction system, protects oil feed pump 1.
Torque converter control system of the present invention, when principal pressure modulating valve 6 regulating system operating oil pressure, increase lock-up clutch pressure, holotype pressure low regime clutch pressure negative-feedback signal, when holotype energising, locking operating mode and low regime clutch work, suitably principal pressure is reduced when ensureing system worked well, decrease the power consumpiton of main oil pump 1, improve the transmission efficiency of speed changer.Operation system setting has two often to drive pilot proportional solenoid valve 13, and its object is to torque converter and be in a certain gear when normally working, if control system meets with unexpected power-off, speed changer can also in particular gears work (except neutral gear, reverse gear).The proportional current that pilot proportional solenoid valve 13, three the second normally closed pilot proportional solenoid valves 14 often driven by first normally closed pilot proportional solenoid valve 12, two is provided by ECU carries out pilot control, and transform pilot control oil pressure, there is provided accurately according to the size of pilot control oil pressure again, stably, respond clutch pressure faster, can realize that clutch fills, the accurate control of oil pressure elevating process when draining the oil as required.
Preferably, this control system also comprises the normally closed pilot proportional solenoid valve 11 of one the 3rd normally closed pilot proportional solenoid valve the 11, three and is connected with pilot pressure modulating valve 5, retarder 2 respectively.Export control command by ECU, power to the 3rd normally closed pilot proportional solenoid valve 11, pressure oil enters retarder 2, realizes downhill retardation function.The proportional current that 3rd normally closed pilot proportional solenoid valve 11 is provided by ECU carries out pilot control, and is converted into the operating oil pressure of retarder 2, and the fluid realizing retarder 2 different fills out the ratio of punching, thus realizes the different braking torque requirement of retarder 2.
This control system also comprises an accumulator Pneumatic valve 22, and accumulator Pneumatic valve 22 is connected with retarder 2 through a gas-liquid accumulator 23.When retarder 2 does not work, in gas-liquid accumulator 21, store the fluid of certain pressure.When retarder 2 needs work, power to the 3rd normally closed pilot proportional solenoid valve 11, accumulator Pneumatic valve 22 is powered simultaneously, and the fluid that gas-liquid accumulator 21 stores by pressurized air advances retarder 2 fast, improves the speed of response of retarder 2.
This control system also comprises a diagnosis valve 17, and diagnosis valve 17 is connected with pilot pressure modulating valve 5, and for judging whether speed changer normally works by the switching state of pressure switch 18.In the present invention, diagnosis valve 17 is two-bit triplet hydraulic control valve, is provided the induction oil pressure of pressure switch 18 by throttle orifice 19.
Concrete, pilot pressure modulating valve 5 is also connected with torque-converters 3 through a torque converter pressure modulating valve 10, torque-converters Flow valve 23, and torque converter pressure modulating valve 10, for limiting the maximum charge oil pressure of torque-converters, provides protection to torque-converters 3.Torque-converters Flow valve 23 is by lock-up clutch oil pressure cntrol, when lock-up clutch works, torque-converters Flow valve 23 directly enters each lubricant housings 24 of torque converter for stoping fluid to enter torque-converters, avoid fluid and flow through the power loss that torque-converters 3 causes.
Above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
