Description
Technical field
This invention is relevant with the intrasystem oil hydraulic circuit of automatic transmission case, in particular, be torque converter clutch (to call " TCC " in the following text) the replacement modulating valve that can reduce the torque converter effect and discharge the loop hydraulic slip, and torque converter effect here and release loop are used for driving torque converter clutch about a kind of.
Background technique
General Motors 4L60-E (to call " GM " in the following text) the gearbox GM gearbox similar with other all has according to certain operational condition mechanism of " locking " their torque converter to some extent.The purpose of locking torque converter is to stablize when vehicle normal speed under high speed can provide direct driving when travelling.Because the coupling of the hydraulic pressure of torque converter always exists some to skid, a part of power can lose, and the Economy of fuel oil also can decrease.When the high engine speed, provide a direct mechanical coupling by gearbox, the locking torque converter can improve the Economy of fuel oil.
This finishes by an electronics/hydraulic torque converter clutch system, and it has utilized a lockup piston that the torque converter case is interior.Lockup piston has friction material at its front surface.When vehicle when normal speed is stable when travelling and needs locking, an electromagnetic coil is activated, it will open torque converter clutch and regulating valve.This can make hydraulic pressure on lockup piston, is pressed to a machined surface of torque converter case.Therefore, lockup piston and torque converter case are locked in together and take action as a unit, and be similar with the manual transmission clutch.When locking no longer was required, a hole can be opened the liquid that makes pressurized and be discharged.So lockup piston is left the torque converter case, rebulid the hydraulic pressure coupling.
Early stage 4L60E gearbox uses the 2nd grade of clutch oil to drive the TCC Operating valve, is actually to be acted on by working connection pressure (line pressure) by a throttle orifice.In the gearbox of this style, TCC modulating valve and separating valve are synthesized in the valve.In the style of upgrading, locking in the electronics torque converter clutch system is to be controlled by the torque converter clutch of a pulsewidth modulation (to call " PWM " in the following text) (to call " PWM TCC " in the following text) electromagnetic coil, it can be reacted to the work cycle that acts on the electromagnetic coil, and output or pilot pressure are provided.
General Motors in 1993 transfer to use the TCC modulating valve of PWM driving, and it is divided into 2 valves that separate, i.e. regulating action valve and separating valve.Therefore, in the 4L60E torque converter of PWM style (1993-1997), in fact 2 torque converter electromagnetic coils that use are arranged in system.PWM TCC electromagnetic coil is sent automatic transmission fluid (to call " ATF " in the following text) to separating valve.Because PWM TCC electromagnetic coil is to the separating valve ringing, it is vibration constantly in valve body.The regulating action valve receives working connection pressure and it is adjusted to a littler pressure, is called as the torque converter effect and presses.The torque converter effect is pressed and is not in fact delivered to torque converter, but is sent to the TCC Operating valve.The TCC Operating valve is driven by the TCC electromagnetic coil.This electromagnetic coil is a simple on/off-type electromagnetic coil in fact, rather than the PWM type.Actual guiding ATF is the TCC Operating valve to torque converter.
General Motors in 1998 are brought into use the torque converter of " EC3 " type.This design can make torque converter upwards slide and never need complete locking from the 2nd grade continuously.This design is intended to improve the Economy of fuel oil and the control of torque converter.Regulating action valve and separating valve be just by slight modification, its function and 1993-1997PWM style identical.
The weakness that these systems had is the pulse flow that is produced when it opens and closes the position cocycle when PWM TCC separating valve.These pulses cause the wearing and tearing in the valve body, cause seepage and abnormal stress reaction of hydraulic oil.Consequently, the vehicle of being furnished with the 4L60E gearbox TCC effect occurs through regular meeting and presses deficiency, causes out of contior cltuch slipping, makes the TCC slippage diagnostic trouble code that torque converter is overheated and generation needs repairing.These symptoms are often caused from TCC modulating valve seepage by ATF, the reduction that causes the torque converter effect to be pressed.
Next original in this respect more already present patents are discussed.One of them example is a U. S. Patent 4,271,939 (to call " 939 " patent in the following text), and it has disclosed one and has made the torque converter hydraulic control system, can guarantee the release of torque converter lockup state.This is by providing a restrictor to make the flow resistance of passage be equal to or greater than the flow resistance of the hydraulic work oil transfer passage of locking control chamber in the hydraulic work oil transfer passage of torque converter.In this control system, first or transfer passage are connected with source and a torque converter chamber of a compressed oil, and second or release channel are communicated with the torque converter chamber, and the 3rd passage is connected with the clutch cavity of locking control or lock-up clutch.Source and third channel that the locking control valve is identical with compressed oil are connected.First passage has restrictor.Because the effect of restrictor, do the time spent when the pressure of third channel and can guarantee the separation of lock-up clutch.
Another example is a U. S. Patent 4,618,036 (to call " 036 patent " in the following text), and it has introduced a kind of hydraulic control system of lock-up clutch of torque converter, even when the release flow of pump is low, lock-up clutch also can guarantee to throw off.This control system has comprised one by engine-driven pump that is used for discharging liquid, torque converter with lock-up clutch, when the hydraulic pressure in locking discharges the chamber is higher than hydraulic pressure in the active chamber of torque converter, the lock-up clutch piston is movable to the clutch release position, system has also comprised an oil circuit pressure regulator valve and throttle orifice, even when the oil circuit pressure that is produced by the oil circuit pressure regulator valve was lower than predetermined value, they can provide a controlled hydraulic communication between torque converter and pump.The outlet valve that 036 patent has used the ring of first guiding valve to form on the oil circuit pressure regulator valve on the bank can have enough hydraulic flows to flow to torque converter through oil pipe when low cruise like this, thereby guarantee the release of lock-up clutch.
Above-mentioned patent is relevant with the torque converter hydraulic control system basically, and they do not disclose improvement the method that valve mechanism is recovered these loop fluid power integrities of replacing is used in the hydraulic control or relevant the passing through in torque converter clutch effect loop.
The U.S. Patent application 09/939,372 that awaits the reply has disclosed an exciter transmission limit valve (to call " AFL " in the following text) assembly, and it contains one be convenient to the replacement hydraulic valve mechanism installed in automatic transmission case first wife valve body.AFL valve guiding oil circuit pressure enters the AFL loop, is gear shift electromagnetic coil, electromagnetic pressure control coil and other hydraulically powered gearbox component feed pressure.This valve mechanism has been used the valve pocket of a comprehensive engagement, and it has entry port and the exhaust port circumferential arrangement along it, and this has reduced the edge carrying significantly, hole wearing and tearing and AFL oil hydraulic circuit seepage.But this patent application does not propose improvement on any structure and the technical advantage of this invention.
