Abstract
The utility model discloses a quick shifting mechanism omitting a gear selecting process, and the quick shifting mechanism comprises shifting fingers, a shifting shaft, a proportional electromagnet, a signal shaft and a shifting position sensor; each shifting shaft is provided with one shifting finger, each shifting finger is provided with one proportional electromagnet drive which is matched with the shifting finger; when one of the proportional electromagnets is electrified, the shifting finger can be pushed to move ahead, and the advancing or idling operation of the reducer can be realized; one signal shaft is fixed on each shifting shaft, one magnet is fixed on the signal shaft, and each signal shaft corresponds to one shifting position sensor; and when in gear shifting, the signal shaft moves along with the shifting shaft, and the shifting position sensor detects the position of the signal shaft in real time, so that a gear position can be determined. Due to the adoption of the quick shifting mechanism omitting the gear selecting process, the gear selecting operation process is omitted, the switching time between any two gears can be maintained consistent, and the shifting speed can be greatly increased.
Description
Technical field
The utility model relates to the automatic gearbox field.
Background technique
Traditional design is that the shared same gearshift of all selector fork axles refers to; When two the gear on same selector fork axle does not switch; To gearshift be referred to adjust to target gear place selector fork axle position earlier; Promptly accomplish the block selecting process earlier, refer to drive the selector fork axle by gearshift again and realize gearshift.A requisite block selecting action is arranged in this process, thereby prolonged the gearshift time, increased the power interruption time in the shift process.Vehicles dynamic performance and ride comfort are caused adverse effect.
The outstanding problem of existing AMT vehicle is the shift process power interruption, gives the ride comfort deleterious impact.A main cause that causes power interruption is the gearshift overlong time.Existing AMT gearshift adopts electric mechanical, electrical liquid or electric three kinds of control modes, the scheme that gearshift refers to; Three kinds of control modes are more complicated all; The control difficulty is high, simultaneously when running into that two gears on same selector fork axle do not switch, and must be through the block selecting process; The time that this block selecting process need is roughly suitable with gearshift, therefore prolonged the gearshift time.
The model utility content
The utility model technical problem to be solved provides a kind of electromagnetic type crash change of speed mechanism that omits the block selecting process; It is a kind of use electromagnetic type control mode; Can omit the crash change of speed mechanism of block selecting process, thereby improve shift speed greatly, improve the power interruption phenomenon.
In order to solve above technical problem, the utility model provides a kind of electromagnetic type crash change of speed mechanism that omits the block selecting process, comprising: gearshift refers to, the selector fork axle, proportion electro-magnet, signal shaft, drive range sensor, magnet; Be equipped with a gearshift on each selector fork axle and refer to, each gearshift refers to have a pair of proportion electro-magnet driving to joining with it; When one of them proportion electro-magnet energising, can promote to move before gearshift is pointed to, thereby realize that speed changer advances retaining or hangs the neutral operation; Fixing signal shaft on each selector fork axle, fixing magnet on the signal shaft, the corresponding drive range sensor of each piece magnet; During gearshift, signal shaft moves with the selector fork axle, the position of magnet on the drive range sensor in real time testing signal axle, thus confirm gear information.
The beneficial effect of the utility model is: omit the electromagnetic type crash change of speed mechanism of block selecting process, use the electromagnetic type control mode, utilized the fast-response of electromagnetic type control mode; The simplification of control mode, the accuracy of positioning control has been omitted the block selecting operating process; Can make the switching time between any two gears consistent; Therefore improved shift speed greatly, the average gearshift time is shortened more than 1/3 than the traditional mechanism gearshift, the power interruption of improving the AMT vehicle has been had remarkable result.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is two schematic representation that gear switches that same gearshift refers to;
Fig. 2 is two schematic representation that gear switches that do not refer in same gearshift.
Embodiment
The utility model AMT automatic transmission adopts the electromagnetic type shift-selecting and changing actuating mechanism to replace the choosing gearshift drag-line mechanism of manual transmission, realizes that vehicle selects gear shift operation.Specifically be, each selector fork axle has the action of the both direction that moves forward and backward, the corresponding gear of the action of each direction, the corresponding proportion electro-magnet of each gear.When speed changer has a plurality of gear, have a plurality of selector fork axles.
Like Fig. 1, shown in 2, be the proportion electro-magnet driving mode.The crash change of speed mechanism of the omission block selecting process that the utility model is related comprising that gearshift refers to 1, selector fork axle 2, proportion electro-magnet 3, signal shaft 4, drive range sensor 5, magnet 6.
Be equipped with a gearshift on each selector fork axle and refer to, each gearshift refers to have a pair of proportion electro-magnet driving to joining with it.When one of them proportion electro-magnet energising, can promote to move before gearshift is pointed to, thereby realize that speed changer advances retaining or hangs the neutral operation.
Each gearshift refers to have the action of both direction of moving forward and backward, corresponding three gear positions, i.e. a neutral gear position and two non-neutral gear positions.
When two gears that refer in same gearshift switched: gearshift referred to move forward or backward under the promotion at proportion electro-magnet; And band selector fork axle moves forward or backward; Signal shaft moves with the selector fork axle; The position of magnet on the drive range sensor in real time testing signal axle realizes switching to another gear from a gear.
Not when two gears that same gearshift refers to switch: the gearshift that has entered into gear refers at first action under proportion electro-magnet drives, and drives the selector fork axle and moves, and is withdrawn into neutral gear position from current shift; In the moment that falls back on neutral gear position; The gearshift of next target gear refers to that under proportion electro-magnet promoted, the selector fork axle that drives target gear place moved, and enters into the target gear; Signal shaft moves with the selector fork axle in the shift process; The position of magnet on the drive range sensor in real time testing signal axle only has current shift to move back retaining in this shift process and the target gear advances two actions of retaining, no block selecting action; Thereby omitted the block selecting time, can realize like this between all gears that the available same time switches.
The utility model is not limited to the mode of execution that preceding text are discussed.More than the description of embodiment is intended in order to describe and explain the technological scheme that the utility model relates to.Conspicuous conversion or the alternative protection domain that also should be considered to fall into the utility model based on the utility model enlightenment.Above embodiment is used for disclosing the best implementation methods of the utility model, so that those of ordinary skill in the art can use numerous embodiments of the utility model and the purpose that multiple alternative reaches the utility model.
