Abstract
The utility model relates to an electrically-controlled hydrodynamic gear shifting system of a multi-gear transmission of a car. The electrically-controlled hydrodynamic gear shifting system is simple in structure and convenient in operation, overcoming the defects of complex gear shifting operations and heavy gear shifting mechanism of the existing multi-gear car provided with a main gearbox and an auxiliary gearbox. The system adopts a friction-type clutch drive gear. Since a clearance is reserved between an external ring gear transmission friction disc (3) and an internal spline shaft transmission friction disc (8), when a hydraulic piston cylinder (4) does not work, no power is transmitted; when an annular hydraulic cylinder (4) is supplied with high-pressure oil, the annular transmission pistons (5) at the two sides extend outward and tightly press the two friction discs together for obtaining friction, the power is transmitted. When the hydrodynamic friction-type clutch mechanism is used in the gear shifting mechanism, the utility model has the outstanding advantages that the fork mechanism of the traditional synchronizing clutch is avoided, the car weight is reduced, the one-key electrically-controlled operation can be realized easily in the hydrodynamic element and the gear shifting action is simplified.

Technical field:
The utility model belongs to a kind of improved system of automanual system change speed gear box, relates to a kind of electrically controlled and hydraulically formula shifting system of automobile multi-shifting speed variator, comprises surge friction clutch formula gearshift and one-touch control circuit.
Background technology:
Since the automobile invention, change speed gear box becomes one of indispensable component part of automobile very soon.Automobile travels under different road conditions and operating mode, requires different actuating speeds and moment of torsion, and these are all realized by change speed gear box; The gear number of change speed gear box is many more, and automobile just has many more chances near desirable actuating speed and moment of torsion, has not only made full use of the horsepower output of driving engine, has improved fuel utilization ratio, and has increased the dynamic property and the ride comfort of running car.So general large-scale special vehicle and engineering truck often have the gear more than eight, adopt the series connected mode of major-minor change speed gear box to obtain more gear number, so cause chaufeur to obtain required gear by controlling two major-minor gear-change hand levers respectively, actuating quantity is bigger during gearshift, cause driving fatigue easily, bring potential safety hazard.
Summary of the invention:
The utility model exists automobile gear shift at many gears engineering truck that the major-minor change speed gear box is housed at present, special-use vehicle etc. and handles weak points such as complicated, gearshift transmission device heaviness, proposes a kind of electrically controlled and hydraulically formula shifting system of simple in structure, control comfort.
The electrically controlled and hydraulically formula shifting system content Description of the utility model automobile multi-shifting speed variator:
Whether the transmission of power of this mechanism is to use the mode of the friction clutch that surges to realize; The inner ring of external toothing has spline, and is identical with the outer ring profile of external toothing gearing friction sheet (3); External toothing gearing friction sheet (3) is arranged with female splined shaft gearing friction sheet (8) interleaved series; The annular hydraulic piston cylinder (4) that is fixed on the gearbox body can feed high pressure oil, and the transmission ram (5) of an annular is respectively arranged in the hydraulic actuating cylinder of symmetric arrangement, and can stretch compresses or the disengaging friction sheet; Output shaft is castellated shaft (7), and the inner ring profile phase of its of bonding and female splined shaft gearing friction sheet coincide; Each dress of piston head end face and external toothing gearing friction sheet outer face posts annular slide watt (9).The break-make of each gear piston cylinder mesohigh oil in major-minor change speed gear box during gearshift all can be by two-position three way magnetic valve by independently key switch control.
With two tween drive shaft 10 shift transmissions is example, and the layout control circuit (has wherein been used simple and easy symbol as the summary 1 described friction disk type gearshift that surges as shown in Figure 3
Replace), A, B, C, D, E, F, H, L are respectively the power lead of the two-position three way magnetic valve of the different transmission gear ring inner carrier actions of control.Press the figure wiring, source switch is a kind of gear of may command just; These ten switches only are connected on the combined switch that allows a simultaneously closed switch, just can make things convenient for and realize a key gear shift control safely.
The beneficial effects of the utility model are, have realized one-touch gear shift operation, having simplified the gearshift action, make driving lighter, thereby reduce the potential safety hazard that may bring because of driving fatigue.This system can save traditional synchronizing clutch in addition, and shift fork, transmission device have been simplified gearbox designs, have alleviated tare, have saved material.Adopt the gearshift of friction clutch formula, can reduce shift impact on the one hand, can play overload protective function on the other hand.

The specific embodiment:
Specific implementation method of the present utility model is as follows:
Used the major-minor change-speed box of this system, gear bonding state in its major-minor change speed gear box is by the solenoid control of two hydraulic pistons by separately, 6 gears of main tank (comprise reverse gear R and overdrive O D), 2 gears of odd-side can be realized the replacing of 10 gears two the casees by various combination.The realization of each gear all only needs to connect each self-corresponding electromagnetic valve gets final product corresponding hydraulic cylinder works.For example will realize 1 retaining, just press 1 position switch, two electromagnetic valve energisings that 1 cooresponding main tank E of retaining and odd-side L are connect are connected high pressure oil to corresponding hydraulic actuating cylinder, promote piston action.Described by content Description 2, be responsible for the E of 1 retaining transmission and the friction lining in the L friction-type engaging and disengaging gear and compress mutually, both frictional engagement, external toothing and female splined shaft move together, and realize power by the function of tween drive shaft to the output shaft transmission.Because it is all gapped between the friction lining in other gear ring, so when its pairing switch is not closed is that hydraulic piston cylinder is not when working, between gear ring and the output shaft because of not contact friction transferring power not, this moment, power transmission line was:---------main tank output shaft---odd-side tween drive shaft---odd-side output shaft (being final power of change speed gear box and rotating speed output shaft) is so optionally realize transmission of power for the main tank tween drive shaft for the change speed gear box input shaft for engine crankshaft.
When pressing other another gear on-offs, 1 cooresponding main tank E of retaining and odd-side L closed electromagnetic valve, cooresponding piston cylinder oil pipe of E, L and fuel tank are connected and emptying, and piston stops to return in the cylinder to external compression, and power stops transmitting; And the cooresponding piston cylinder of another gear will be worked, and finishes the transmission of power between another shift gear; In like manner, realize the steady switching of other gear.
Under the situation of not pressing any switch, be considered as hanging neutral, do not accept the transmission of power on the output shaft, realize the purpose of neutral.
