Problems solved by technology

[0004] (1) The dry dual clutch is composed of two manual transmission clutches. The manufacturing process is complicated. Repeated parking and starting in the traffic jam section will easily cause the friction plate to overheat, and the driving comfort is poor. It is hydraulic control, and the pressure control accuracy is extremely high. The cost is high, the processing of parts is difficult, the qualified rate of parts is low, the failure rate is high, and repair is difficult
[0005] (2) The driving comfort of wet dual-clutch transmission is better than that of dry-type dual-clutch transmission, and the oil-cooled friction plate does not cause over-burning phenomenon, but the full hydraulic control system is difficult to process parts, the qualified rate of parts is low, and the manufacturing cost is high , difficult to repair
[0006] The above two types of dual-clutch transmissions are all hydraulic control systems, with high manufacturing cost, complex structure and control, high manufacturing and processing costs, high failure rate, and difficult maintenance

Embodiment 1

[0023] Such as figure 1 As shown, in order to complete the speed change requirements of the transmission system: the double-plate clutch mechanism of the present invention includes an inner shaft pressure plate rotating cage 32 uniformly distributed on the circumference of the annular end face bearing 38, and the pressure rod passes through the outer shaft to fix the outer gear hub 33, and the pressure rod There is a steel ball chute at the perforation to ensure the smooth reciprocating movement of the pressure rod. The inner shaft pressure plate cage 32 presses the inner shaft clutch plate pressure plate 12 through the end surface separation bearing, and the inner shaft pressure plate cage 32 fixes the outer teeth with the outer shaft. The hub 33 rotates together. The external shaft fixed external tooth rotating hub 33 is in the form of external teeth to cooperate with the friction plates, and the external shaft 22 starts power output when the external shaft clutch plate pres...

Embodiment 2

[0036] figure 2 Another embodiment of the dual plate clutch mechanism is shown.

[0037]The input shaft double clutch rotating hub 6 of this double-plate type clutch mechanism changes the same wall to have internal teeth plus external teeth, the internal teeth drive the internal shaft, and the external teeth drive the external shaft, eliminating the inner gear hub wall of the outer ring. The outer shaft is fixed to the inner gear hub 44. The outer gear of the first embodiment is changed to an inner gear, and two rows of cylindrical pressure rod holes with different inner diameters are added in the circumferential direction. The steel ball chute ensures smooth reciprocating movement of the pressure rod. The pressure plate 34 of the outer shaft clutch plate is added to the pressure-bearing end surface of the friction plate in the circumferential direction, and two rows of cylindrical pressure rods with different inner diameters are uniformly distributed in a positive row or in...

Abstract

The invention discloses a double-plate clutch mechanism. The double-plate clutch mechanism comprises a front shell, a front shell sealing end cover, a middle shell, a back shell, an input shaft double-clutch rotating hub, an inner shaft, an outer shaft, an inner shaft pressure plate rotating cage and an outer shaft fixed outer gear hub, wherein the input shaft double-clutch rotating hub is used for driving the inner shaft or the outer shaft through inner and outer ring clutch friction plates; the inner shaft pressure plate rotating cage rotates together with the outer shaft fixed outer gear hub or an outer shaft fixed inner gear rotating hub. The invention discloses a mechanical transmission. The mechanical transmission comprises the double-plate clutch mechanism. The external input energy efficiency is maximized. Through application of the double-plate clutch mechanism in the field of automobiles, an engine can work in a most fuel-saving region, and a vehicle adapts to various road conditions. The double-plate clutch mechanism works stably without impact, the copper loss and iron loss of a mechanical system are reduced, the mechanical life is prolonged, and an excellent energy-saving effect is achieved. The double-plate clutch mechanism is suitable for transport vehicles (vehicles, planes and ships) and other energy-saving speed regulating devices.

Description

technical field [0001] The invention relates to the field of clutches, in particular to a double-plate clutch mechanism and a mechanical transmission including the double-plate clutch mechanism. Background technique [0002] The double-plate clutch is a wet-type multi-plate dual clutch. It uses the vector control pressure of the servo motor to compress the clutch friction plates to drive the power output of the inner shaft and the outer shaft. When a certain group of clutches is working, the clutch pressure plate makes a group of circular The spring (coil spring or butterfly spring) is pressed, which will drive the group of pressure plates to press the clutch friction plate, and under the action of friction, the inner tooth and outer tooth friction plate will be combined into a whole, and the friction plate teeth will follow the input shaft The tooth rotation of the double clutch hub is also connected with the fixed hub of the inner tooth or the fixed hub of the outer shaft ...
