Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, 2 and 3, the present embodiment provides a transmission capable of avoiding power waste, which includes an input shaft 10, an output shaft 20, an intermediate shaft 30, a dual switching clutch 40, a housing 50 and an overrunning clutch 60. The overrunning clutch can be a wedge type overrunning clutch, a ball type overrunning clutch and a ratchet wheel type overrunning clutch. The overrunning clutch is sleeved on the output shaft and is positioned between a gear of a gear pair of the output shaft and the output shaft, and the overrunning clutch is an important part with power transmission and separation functions between a prime motor and a working machine or between a driving shaft and a driven shaft in the machine. The overrunning clutch is a device with a self-clutch function by utilizing the speed difference change of a driving part and a driven part.
For example, the wedge overrunning clutch uses a profiled wedge instead of a roller as a wedge member, and is a clutch with a friction pair consisting of a wedge 61, an inner race 62 and an outer race 63. When the inner raceway, the outer raceway and the wedge block do not move relatively, the rotation directions are the same, the rotating speeds are equal, the torque can be transmitted, otherwise, the torque is transmitted in a relative sliding mode, and the sliding state without the torque transmission is called overrunning. The wedge overrunning clutch mainly comprises a basic type, a non-inner-roller-way type and a type with a bearing. The connection form of the device is key connection, gear connection, belt wheel connection, chain wheel connection, bolt connection and the like.
When the automobile is in operation, an engine or a motor of the automobile drives an input shaft of a transmission to rotate, the input shaft inputs power to an intermediate shaft through a gear pair, and the intermediate shaft and the gear pair on the output shaft output the power to wheels of the automobile through the output shaft, so that the effect of driving the automobile to move is achieved. Or the power on the input shaft can be directly transmitted to the output shaft through the control of the switching type double clutch, and a specific transmission path is explained below. At this time, the output shaft and the overrunning clutch are in a connected state, namely the overrunning clutch and the output shaft rotate together. And when the derailleur is the state of neutral gear, the output shaft of derailleur can continue to drive rotatoryly by the auto wheel, and second separation and reunion piece rotational speed descends when there is not power, the rotational speed of output shaft is greater than first output gear, clutch surging when certain rotational speed difference exists in the inner and outer lane of freewheel clutch this moment has not been discombined, first output gear on the output shaft this moment then can not follow the output shaft rotation through freewheel clutch, make the output shaft idle running, can not influence the power take off of derailleur before the neutral gear, the effectual extravagant problem of power of having avoided the derailleur, the load loss that the derailleur caused has been reduced simultaneously, the life of derailleur has been improved.
The axle head of input shaft can establish through the bearing housing in this embodiment with the terminal surface dead eye of output shaft, and then reaches the effect of the central line collineation of input shaft and output shaft, and the input of input shaft and the output of output shaft then run through the relative both sides wall of casing respectively and install on the casing, the input of input shaft and jackshaft is connected in the transmission, the output and the output shaft transmission of jackshaft are connected, the central line of jackshaft is on a parallel with the central line setting of input shaft in the casing.
The input shaft is provided with a first input gear 11, the output shaft is provided with a first output gear 21, and the intermediate shaft is provided with a second input gear 31 and a second output gear 32. The first input gear and the second input gear are meshed with each other to form a first gear pair, and the first output gear and the second output gear are meshed with each other to form a second gear pair. The switching type double clutch is arranged on an input shaft or an output shaft between the first input gear and the first output gear, and mutually exclusive clutch operation is carried out on the first gear pair and the second gear pair. When the mutual exclusion is that the first gear pair is in a closed state, the second gear pair is in an open state; conversely, when the second gear pair is in the engaged state, the first gear pair is in the disengaged state. Therefore, two different routes of power transmission modes can be carried out on the first gear pair and the second gear pair through the switching type double clutch.
Specifically, taking the example that the switching type double clutch is arranged on the input shaft, the first route is as follows: the power of the input shaft can be directly transmitted to the output shaft through the second clutch block; the corresponding second route is: the input shaft transmits power to the intermediate shaft through the first gear pair and then transmits the power to the output shaft through the second gear pair, and the effect of changing two gears is achieved.
Also included in this embodiment is a bearing 70, with the overrunning clutch disposed between the first output gear and the output shaft, and the bearing disposed between the overrunning clutch and the first output gear. At the moment, the overrunning clutch is a wedge overrunning clutch with a bearing, when the overrunning clutch rotates around one direction, one end of a wedge in the overrunning clutch can tilt through the action of eccentric gravity, and then the wedge abuts against an outer raceway of the overrunning clutch, so that the output shaft rotates along with the first output gear. When the output shaft is driven by the wheels to rotate and the engine stops, the gears are in a static state, the other ends of the wedge blocks in the overrunning clutches are tilted under the action of centrifugal force, and further the outer rolling ways of the overrunning clutches are far away, namely no relative motion exists between the inner rolling ways and the wedge blocks of the overrunning clutches, the output shaft can be ensured not to drive the first output gear to rotate through the bearing, the purpose that the gears inside the gearbox such as the output gear and the like can not be driven to rotate by the automobile wheels is achieved, and the problem of power waste of the gearbox is avoided.

In this embodiment, the first clutch block is connected to the first input gear of the input shaft, and the second clutch block is connected to the first output gear, so that the first switching dual clutch can perform mutually exclusive clutch control on the first gear pair of the input shaft and the second gear pair of the output shaft. In this embodiment, for example, the first oil guiding passage pushes the double-end piston body to move toward the first output gear after oil enters, and the second oil guiding passage pushes the double-end piston body to move toward the first input gear after oil enters.
In this embodiment, the first friction plate set 411 and the second friction plate set 421 have the same structure, and the components thereof may be a friction plate and a steel plate or a friction plate and a friction plate, which are described in this embodiment by taking a friction plate and a steel plate as an example.
