Description

Select lever control device of automatic transmission vehicle

The present invention relates to a select lever control device for an automatic transmission vehicle.

As is well known, an automobile uses an internal combustion engine that burns fuel in an engine and converts thermal energy generated therein into kinetic energy, and is used as a means of transporting and moving cargo.

Such automobiles include a transmission for appropriately controlling the driving force of the engine and transmitting it to the axle (drive wheel). Since the gearbox does not have sufficient maneuvering power during the initial driving of the engine, it reduces the rotational force of the engine during the initial driving to increase the driving torque, or converts or increases the reduction ratio when the speed is increased so that it can be properly operated according to the driving condition of the vehicle. do. Many types of such transmissions have been developed, such as manual transmissions and automatic transmissions. The manual transmission is difficult to operate as the driver selects a gear ratio according to each driving condition, and thus requires a skilled driving technique. On the other hand, the automatic transmission device is suitable for the planetary gear assembly is properly controlled by the electronic control signal of the computer that receives the detection signal from the various sensors for detecting the driving speed and load state of the vehicle, and various valves that open and close according to the signal. It has the disadvantage that the structure is more complicated than the manual transmission, the output efficiency is low, and it is expensive, but it is easy to operate because it does not need to perform a separate operation for shifting while driving. The range of use is expanding rapidly. In addition to this, in recent years, a so-called continuously variable transmission has been developed to remove the shift stage so that there is no shift shock at the time of shifting.

The automatic transmission does not have a mechanical clutch device that transmits or blocks engine power to the transmission, and uses a torque converter using a fluid coupling. Therefore, only the accelerator pedal and brake pedal are provided in the driver's seat, and the clutch pedal necessary for power control is not provided. . Therefore, only the operation of the accelerator pedal and the brake pedal can increase or decrease the driving speed of the vehicle. However, the automatic transmission also determines the driving direction of the vehicle such as forward or reverse, and the determination of whether to transmit power such as neutral, driving, parking, etc. should be selected by the driver. Therefore, a select lever control device is provided for the automatic transmission vehicle.

The select lever control device includes a select lever, and the select lever includes a lifting rod that moves along a plurality of select positions formed by a step, and the lifting rod is lifted by a separate operating means and moves in the select position. This is done. The select position is mainly formed on the detent plate arranged vertically on the base plate.

Referring to Figure 1 will be described schematically the configuration of the select lever control device. According to this, the detent plate 20 is fixed to the base plate 10 installed in the vehicle body. The detent plate 20 includes a plurality of select positions ｛parking position (P), reverse position (R), neutral position (N), travel position (D), and second speed position (divided by predetermined steps on the surface). 2) The low speed position L 'is sequentially formed. The number of locking holes 22 corresponding to each of the select positions is formed on the detent plate 20 above the select position.

In addition, a select lever assembly 30 is rotatably supported with respect to the detent plate 20. The select lever assembly 30 has a rotating shaft 32 rotatably coupled to the lower end of the detent plate 20, and a hollow shaft having a lower end fixed on the rotating shaft 32 and having a cutout 34a formed therein. 34) is provided. A knob (not shown) to be gripped by the driver is installed at the upper portion of the hollow shaft 34, and a lifting rod 36 elastically supported to have a force directed to the upper portion is always installed inside the hollow shaft 34. The lifting rod 36 is moved to the lower portion of the hollow shaft 34 by a button provided on the knob. In addition, a detent pin 36a which protrudes in the direction perpendicular to the axial direction and moves along the select position is fixed to the lower end of the lifting rod 36, and is positioned on at least one select position. In addition, the housing 40 is fixed on the hollow shaft 34, the locking ball 42 is supported on the spring so as to project toward the detent plate 20 at all times. The locking ball 42 is fixed to a position corresponding to the locking hole 22 and is formed to pass the locking ball 42 through the locking hole 22 when the hollow shaft 34 is rotated.

On the other hand, one side of the detent plate 20 is provided with a device for preventing the select lever assembly 30 is moved from the parking position (P) to the reverse position (R) due to a misoperation. That is, a locking lever 50 is installed which interferes with the detent pin 36a and restricts the movement of the select lever in the parking position. The locking lever 50 is operated by a specific signal (brake signal) to move and lift the locking lever 50. A solenoid 60 is installed to allow the detent pin 36a of the rod 36 to disengage.

Looking in more detail with reference to Figure 2, the locking lever 50 is formed in a substantially L-shape is fixed to be rotatable on one side of the detent plate 20, the fixing piece having a fixing hole 54 on one side ( 52 is formed, and the other end is formed with a locking ring 56 that interferes with the detent pin 36a of the select lever 30. The locking ring 56 is formed so as to always be located below the select position (parking position P) formed in the detent plate 20. The solenoid 60 is fixed to the detent plate 20 by the fixing bracket 62 in a vertical state. The solenoid 60 is moved up and down by the suction force of the electromagnet via a coil spring 67. The running burr 66 is fitted. At this time, the moving rod 64 is fitted so as to penetrate through the running lever 66 to protrude to one side of the running lever 66, the end of the running lever 66 is fixed to the locking lever (50) 52 is fitted into the fixing hole 54. In addition, the squeeze lever 66 protruding to one side of the fixing hole 54 is fitted with the squeezing burr 68 and at the same time the washer 69 is fitted to the end of the moving rod 64 so as not to be separated from the fixing hole 54. It was not. On the other hand, the moving rod 64 is always carried upward by the coil spring 67, so that the locking ring 56 of the locking lever 50 is located in the lower position of the select position (main position P). The tent pin 36a interferes with the parking position P from being moved. In this state, when a specific signal (brake signal) is applied, the moving rod 64 of the solenoid 60 suppresses and descends the coil spring 67 force, and at the same time, the locking lever 50 also rotates and the engaging ring 56 is applied. Also, the detent pin 36a moves from the parking position P to move from the parking position P.

The operating state of the select lever control device having such a configuration will be briefly described as follows. When the knob is pulled forward or backward, the select lever rotates about the rotation shaft 32. At this time, the lifting rod 36 moves smoothly between the neutral position (N) and the driving position (D) without any manipulation. Further, the movement from the first speed position L of the select position to the second speed position 2 and the neutral position N can also be moved without jamming. And the movement from the reverse position (R) to the driving position (D) is also not limited. However, movement in a specific direction and position is limited in order to prevent sudden driving state change during driving due to misoperation. That is, moving from the neutral position (N) or the traveling position (D) to the second speed position (2) or the first speed position (L) or the reverse position (R) and the parking position (P) is the The tent pin 36a is caught by the step of each select position, and movement is restricted. Therefore, when such a movement is required, it is possible to move to the selected position only by pressing the button provided on the knob and moving the knob while the detent pin 36a of the lifting rod 36 is separated from the select position.

In particular, in the parking position (P), even when entering or exiting, it is necessary to press the button installed on the knob to move to another position. In this case, when the brake is not pressed, the deceleration of the lifting rod 36 The tent pin 36a is restricted in movement by the locking lever 50. Therefore, when moving from the parking position (P) to another position, it should be assumed that the solenoid 60 must release the detent pin 36a from the fixed state by moving the locking lever 50 by pressing the brake. This is a supplementary means installed to prevent a safety accident because there is a risk of sudden backward or sudden start of the vehicle when freely shifted from the parking position to another position.

However, in the conventional selector device of the automatic transmission vehicle having the configuration described above, the locking lever 50 is not rotated smoothly so that the detent pin 36a does not move from the parking position P to another position. There was a problem that is not made smoothly.

That is, while the locking lever 50 rotates about the hinge point, the moving rod 64 of the solenoid 60 moves linearly, and the mechanical friction and interference generated between the linear and the rotary motions are The grinder 66 is attenuated. However, due to the change over time due to long-term use, the durability of the connecting lever 66 is weakened and thus loses its function. As a result, the locking lever 50 does not rotate smoothly, so that the detent pin of the select lever assembly 30 is reduced. A problem arises in that the shift operation is not smoothly performed because 36a cannot be separated from the parking position P. FIG.

The present invention is conceived in view of the above problems, the purpose of which is to configure the solenoid having a locking rod to limit the movement of the detent pin to increase the operating efficiency and reduce the number of parts, thereby reducing the manufacturing cost It is to provide a select lever control device for.

On the other hand, the select lever assembly 30 is rotatably supported relative to the detent plate 20 is provided. The select lever assembly 30 has a rotating shaft 32 rotatably coupled to the lower end of the detent plate 20, and a hollow shaft having a lower end fixed on the rotating shaft 32 and having a cutout 34a formed therein. 34) is provided. A knob (not shown) to be gripped by the driver is installed at the upper portion of the hollow shaft 34, and a lifting rod 36 elastically supported to have a force directed to the upper portion is always installed inside the hollow shaft 34. The lifting rod 36 is moved to the lower portion of the hollow shaft 34 by a button provided on the knob. In addition, a detent pin 36a which protrudes in the direction perpendicular to the axial direction and moves along the select position is fixed to the lower end of the lifting rod 36, and is positioned on at least one select position. In addition, the housing 40 is fixed on the hollow shaft 34, the locking ball 42 is supported on the spring so as to project toward the detent plate 20 at all times. The locking ball 42 is fixed to a position corresponding to the locking hole 22 and is formed to pass the locking ball 42 through the locking hole 22 when the hollow shaft 34 is rotated.

On the other hand, a solenoid 100 is provided on one side of the detent plate 20 to limit the movement of the select lever by interfering with the detent pin 36a of the lifting rod 36. The solenoid 100 has a locking rod 102 which is moved to the first position A and the second position B by a specific signal (brake signal) as shown in FIGS. 4A and 4B. 102 is located in the lower portion of the parking position (P) of the detent plate 20 is installed in the transverse direction to block the entrance of the parking position (P). The locking rod 102 has a cutting groove 104 orthogonal to the axial direction and is always located in the first position A by the coil spring 106, and when a specific signal (brake signal) is applied, the second position B is applied. It is configured to move to). On the other hand, when the locking rod 102 is located in the second position (B), the center of the cutting groove 104 and the parking position (P) is configured to be arranged on the same axis.

In the solenoid 100 having such a configuration, when the locking rod 102 is positioned at the first position A, the detent pin 36a interferes with the side surface of the locking rod 102 and moves backward from the parking position P. Movement to (R) is limited, and when the locking rod 102 is moved to the second position by the brake signal, the cutting groove 104 and the parking position P of the locking rod 102 are positioned in the same line, so that the detent is detented. Pin (36a) is to be moved along the cutting groove 104 can be moved to the reverse position (R). On the other hand, when the detent pin 36a enters the parking position P from the reversing position R, the tip of the locking rod 102 is set at a predetermined angle so that the entry is not restricted. The detent plate 20 has guide pieces 20a which are in contact with both sides of the locking rod 102 to guide the locking rod 102 in a linear motion and at the same time the detent pin 36a is inclined. To support the locking rod 102 receives a load of.

The operation of the present invention having such a configuration will be briefly described. First, when the knob is pulled forward or backward, the select lever rotates about the rotation shaft 32. At this time, the lifting rod 36 is able to move from the first speed position L of the select position to the second speed position 2 and the travel position D without jamming. And moving from the reverse position (R) to the neutral position (N) is also not limited. However, movement in a specific direction and position is limited in order to prevent sudden driving state change during driving due to misoperation. That is, moving from the driving position D to the second speed position 2 or the first speed position L or the reversing position R and the parking position P means that the detent pin 36a of the lifting rod 36 is moved. The movement is restricted by the step of each select position. Therefore, when such a movement is required, it is possible to move to the selected position only by pressing the button provided on the knob and moving the knob while the detent pin 36a of the lifting rod 36 is separated from the select position.

In particular, in the parking position (P), even when entering or leaving, it is necessary to press the button installed on the knob to move to another position, and the movement from the neutral position (N) to the driving position (D) is also restricted. Press to allow movement. Referring to FIG. 4A, the detent pin 36a is located at the parking position P as the driver selects the parking position P. Referring to FIG. In this state, when the select lever is moved without applying the brake, the detent pin 36a of the lifting rod 36 interferes with the side of the locking rod 102 of the solenoid 100 at the first position A. FIG. Movement is restricted by this. Therefore, when moving from the parking position (P) to another position by pressing the brake to move the locking rod 102 of the solenoid 100 to the second position (B) to release the detent pin (36a) in a fixed state. That is, when the brake is applied, a specific signal is applied, and accordingly, the locking rod 102 of the solenoid 100 depresses and moves the coil spring 106 force as shown in FIG. 4B, and at the same time, the cutting groove of the locking rod 102 The detent pin 36a is located at the parking position P as 104 and the parking position P are co-located so that the detent pin 36a is separated from the parking position P along the cutout groove 104. It can move naturally to the reverse position (R). On the contrary, when the detent pin 36a enters the parking position P from the reversing position R, when the detent pin 36a is pushed out of the step by pressing a button, the detent pin 36a is locked. The road 102 naturally moves to the parking position P along the inclined surface of the tip.

As described above, the select lever control device of the automatic transmission vehicle according to the present invention is configured to limit or allow the movement of the detent pin even by the solenoid having the locking rod, thereby increasing the operating efficiency and reducing the number of parts, thereby producing the cost.
