Description

Dual function shifting device

The present invention relates to an automatic transmission shifting device for a vehicle in which an automatic shift mode and a manual shift mode are applied at the same time. More particularly, the manual mode path is integrally connected to the automatic mode path to form a driver's manual shift. The present invention relates to a dual function shifting device which prevents down and upshifting operations, expands the freedom of designing a path in the manual mode, and realizes a manual mode path suitable for the driver's operation.

The transmission of the vehicle is installed between the clutch and the propulsion shaft, and serves to increase or decrease the rotational force of the engine according to the change of the driving state of the vehicle, and also has a reverse device for reversing the vehicle.

In other words, the transmission is installed between the engine and the propulsion shaft and transfers the power of the engine to the driving wheels by changing the rotational force and speed to suit the driving state of the vehicle.

Such transmissions include a manual type shifting at a constant gear ratio and an automatic transmission shifting at an infinite gear ratio.

In the case of a manual transmission, there are a direct operation type in which a gear shift lever is directly attached to a transmission, and a remote control type in which a transmission lever and a transmission are separated from each other by a link or a wire.

The direct operation type is a type in which the gear moves directly from the shift lever via the fork shaft and the shift fork. There are three fork shafts: 1,2 speed, 3, 4 speed, and reverse, and the front end of the shift lever is connected to the groove at the end so that it can slide back and forth. The gear shift fork is assembled to the fork shaft so that the tip is fitted in the groove of each clutch gear. The fork shaft is equipped with a locking ball and a spring to keep each gear in the determined shifting position. It provides a moderation while shifting and prevents the gear from falling out.

In order to prevent double coupling of gears, interlock mechanisms are installed. The interlock mechanism has two grooves on the center shaft and one groove on the left and right shafts, and interlock pins are inserted between them. When one fork shaft moves, the interlock pin is inserted into the groove of the other fork shaft, and the shaft is fixed to prevent double engagement of the gear.

On the other hand, the automatic transmission is a device in which the action of the clutch and the action of the transmission are automatically made according to the driving speed or the load of the vehicle.

This automatic transmission selection pattern indicates the transmission function when the driver manually selects the shift lever. There are six types of P-R-N-D-2-L.

P represents parking, R represents reverse, N represents neutral, D represents travel, 2 represents second, and L represents lockup.

The parking range P range is possibly the same as the N range, but if the shift lever is set to P range, the parking pole is inserted into the outer gear of the oil distributor and the output shaft is mechanically fixed.

In the R range, the front clutch and the low speed reverse brake are activated. Because of this, rotation of the input shaft is transmitted from the connecting cell to the sun gear through the front clutch drum, and since the rear planetary gear carrier is fixed to the low speed reverse brake, the rotation direction of the sun gear is reversed by the rear planet gear pinion. The resultant rear inner girder, ie the output shaft, decelerates and rotates in the reverse direction.

In the case of the N range, the clutch brake band does not operate, so the power of the input shaft is not transmitted to the output shaft.

The D range is the drive range. In the first speed, the rear clutch and the one-way clutch act. In the second speed, the rear clutch and the band brake act. The sun gear is fixed. In the third speed, the front clutch and the rear are fixed. The clutch will work.

There is no shift up or shift down in the second range.

The L range is used when climbing a steep uphill road, or when a strong engine power or an engine brake is required when going down a steep slope.

However, the shift operation of the automatic transmission has a closed end that the response is slow.

In view of such a problem, recently, a manual mode path is configured on the normal auto mode path line or a path of an existing manual transmission is used.

1 is a schematic plan view showing a conventional combined shifting device.

As shown in the related art, the automatic mode path 1 and the manual mode path 3 are spaced in parallel to each other so as to be operated using the respective select levers 2 and 4, and the paths 1 and 3 Is usually done in a straight line.

In other words, when the automatic mode pass 1 is used, the select lever 2 is shifted up and down (UP-DOWN), and when the manual mode pass 3 is used, the select lever 4 is up and down (UP). -DOWN) to shift.

However, in the conventional combination shifting device, the automatic mode path 1 and the manual mode path 3 are separately configured, and the configuration thereof becomes complicated, and the driver may be confused, and the selector lever 2 ( 4) operation is up and down (UP-DOWN) method, there is a problem such as narrowing the choice according to the driver's taste.

The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to prevent the down, upshifting operation of the driver during manual shift, to increase the freedom of pass design of the manual mode, and also to The present invention provides a dual function shifting device that realizes a manual mode pass that is suitable for an operation taste and does not complicate the configuration thereof.

A dual function shifting apparatus of the present invention for achieving the above object is formed so as to connect the manual mode path in a direction perpendicular to the automatic mode path having a normal automatic transmission shift range, the manual mode path The first path includes a transverse path for converting an automatic mode path and a manual mode path, a first path for shifting a vehicle speed stage according to a driver's selector lever operation, and a second path formed at a predetermined angle with the first path. At the ends of the path and the second path, an elastic member for enabling the return of the selector lever and a sensor for detecting the operation of the selector lever are installed. A connection between the transverse path and the manual mode path includes a latching jaw of the selector lever and a selector lever Characterized in that the sensor installed to detect.
