Description

  The present invention relates to a speed change operation device that performs a speed change operation of a transmission and a method of connecting a select operation transmission member thereof.

A manual transmission mounted on a vehicle such as an automobile is a shift that moves a shift operation part to the left and right to select a shift member to be operated, and then moves the shift operation part back and forth to engage a gear. It is common to have a so-called H-type shift pattern that operates.
In the case of a conventional 5 speed forward and 1 speed reverse transmission, which has been generally used in the past, there are three rows of select positions in the left-right direction, for example, forward and backward with the speed change operation unit pushed to the left from neutral. By moving the shift operation unit forward and backward from 1st, 2nd and neutral, the 3rd and 4th gears, 5th and reverse are selected from the neutral state while the shift operation unit is pushed to the right.

In recent years, in order to improve the running performance by cross ratio and to improve the fuel consumption rate by increasing the ratio coverage, the manual transmission is increasingly multistaged to, for example, 6 speeds or more. In this case, since the select position in the left-right direction increases to four or more rows, some countermeasure is required to prevent an erroneous operation such as erroneously shifting to the reverse direction when trying to select the forward gear.
For example, in Patent Document 1, in a shift lever of a manual transmission having six forward speeds and one reverse speed, the reverse check member is retracted only when the ring-shaped reverse operation portion provided on the shift lever is pulled up. It describes what made it possible to shift to reverse.

(The shift forks other than the 5th to 6th speeds are not shown in the drawings after FIG. 2)
FIG. 3 is a view of the speed change operation device 100 as viewed from the rear (the longitudinal direction of the rotating shaft and the rear of the vehicle when mounted vertically), and is a view taken along the line III-III in FIG.
2 and 3 both show a neutral state.
As shown in FIGS. 1 to 3 and the like, the speed change operating device 100 includes a 1-2 speed shift fork 101, a 3-4 speed shift fork 102, a 5-6 speed shift fork 103, a reverse shift fork 104, and a 1-2 speed.

  The fork rods 111 to 114 are columnar shaft portions that are fixed to the corresponding shift forks 101 to 104, respectively, and are arranged in parallel with the rotation shaft of the manual transmission 1. The fork rods 111 to 114 support the shift forks 101 to 104 so as to be movable in the axial direction with respect to a transmission case (not shown). Further, each fork rod other than the 5-6 speed fork rod 113 is arranged to protrude rearward from each shift fork, and transmits the force input from the arm shifter 120 to each shift fork. The 5-6 speed fork rod 113 is arranged to protrude forward from the 5-6 speed shift fork 103.

  A 1-2 speed shifter that engages with an arm shifter 120 is provided at the rear end of the 1-2 speed fork rod 111, 3-4 speed fork rod 112, reverse fork rod 114, and 5-6 speed shift fork 103. An engaging portion 111a, a 3-4 speed shifter engaging portion 112a, a reverse shifter engaging portion 114a, and a 5-6 speed shifter engaging portion 103a are provided. The shifter engaging portion functions as a shift member according to the present invention. In particular, the reverse shifter engaging portion 114a is an outermost row shift member arranged in the outermost row in the select direction. The configuration of each shift member will be described in detail later.

The arm shifter 120 is provided in the vehicle interior and transmits the movement of the shift lever operated by the driver to the fork rods 111 to 114.
Here, the configuration of the shift lever will be described. FIG. 4 is an external perspective view of the shift lever as viewed from above the vehicle interior side and obliquely from the rear side.
The shift lever unit 200 includes a base portion 201, a shift lever 202, a shift knob 203, a slider 204, a reverse check member 205, and the like.

The base portion 201 is a frame-like member that is fixed to, for example, an upper surface portion of a floor tunnel of the vehicle body and serves as a base portion of the shift lever unit 200.
The shift lever 202 is a shaft-like member that is swingably attached to the base 201 via a spherical bush. The movement of the shift lever 202 is transmitted to the arm shifter 120 in the manual transmission 1 using transmission means such as a shift cable and a select cable.
The shift knob 203 is a spherical member attached to the upper end portion of the shift lever 202. The shift knob 203 is an operated part that is gripped and operated by a driver.
The shift lever unit 200 performs a shift operation and a select operation using a so-called H-shaped pattern. When the shift knob is moved back and forth from the neutral position, the shift lever unit 200 is shifted to the third and fourth speeds, respectively, and the shift knob is pushed to the left from the neutral position. If it is moved back and forth in the state, it is shifted to the 1st and 2nd speeds respectively, and if it is moved back and forth with the shift knob pushed to the right from the neutral position, it is shifted to 5th and 6th speeds, respectively. Further, when the slider 204 is lifted to the shift knob 203 side and the shift knob 203 is pushed back to the right side from the 5th to 6th speeds, it is shifted to the reverse.

The slider 204 is formed in an annular shape, and is a member in which the shift lever 202 is inserted on the inner diameter side thereof, and is provided below the shift knob 203. The slider 204 enables selection to reverse by sliding the shift lever 202 toward the shift knob 203 side.
FIG. 5 is a diagram showing the shift lever in a state where the position of the 5th to 6th speeds is selected.
The reverse check member 205 is a member that is provided at an intermediate portion of the shift lever 202 and moves in the axial direction of the shift lever 202 in conjunction with the slider 204. When the slider 204 is not operated, the reverse check member 205 interferes with a reverse check wall 201a provided on the base 201 as shown in FIG. As a result, the selection operation further toward the reverse side than the 5-6 speed position of the shift lever 202 is prevented, and the shift to the reverse due to an erroneous operation is prevented. When the driver pulls up the slider 204, the reverse check member 205 slides upward (toward the shift knob 203 side). In this state, the reverse check member 205 gets over the upper end of the wall 201a and moves the shift lever 202 to the reverse select position. It becomes possible to make it.

As shown in FIGS. 2 and 3, the arm shifter 120 includes a shaft portion 121, an arm portion 122, a forward engagement portion 123, a reverse engagement portion 124, and the like.
The shaft portion 121 is a columnar member, and extends substantially in the front-rear direction, and is inclined so that the front end portion is slightly lower than the rear end portion. The shaft portion 121 rotates around the central axis with respect to the transmission case in response to a selection operation for moving the shift knob 203 in the lateral direction. Further, the shaft portion 121 moves in the axial direction with respect to the transmission case in accordance with a shift operation for moving the shift knob 203 in the front-rear direction.
As shown in FIG. 2, the height of the front end portion of the shaft portion 121 is substantially the same as that of the reverse fork rod 114. Further, the 5-6 speed fork rod 113, the 3-4 speed fork rod 112, and the 1-2 speed fork rod 111 are sequentially arranged on the lower side of the reverse fork rod 114 substantially along the vertical direction.

The arm portion 122 is a lever-like portion that is fixed to the front end portion of the shaft portion 121 and protrudes in the radial direction of the shaft portion 121. For example, in the case of the present embodiment, the arm portion 122 is formed to protrude downward from the shaft portion 121.
The forward engagement portion 123 is a protrusion provided at the lower end portion of the arm portion 122 and protruding downward. When the forward gear is selected, the forward engagement portion 123 is the above-described 1-2 speed shifter engagement portion 111a, 3-4 speed shifter engagement portion 112a, and 5-6 speed shifter engagement portion 103a. Is selectively engaged with any one of the above.

As shown in FIG. 3, the 1-2 speed shifter engaging portion 111a, the 3-4 speed shifter engaging portion 112a, and the 5-6 speed shifter engaging portion 103a move the forward engaging portion 123 during the select operation. They are sequentially arranged in a line substantially along the direction of the trajectory. That is, in the case of the present embodiment, the 1-2 speed shifter engaging portion 111a, the 3-4 speed shifter engaging portion 112a, and the 5-6 speed shifter engaging portion 103a are arranged substantially in the horizontal direction. Yes.
The 1-2 speed shifter engaging portion 111a, the 3-4 speed shifter engaging portion 112a, and the 5-6 speed shifter engaging portion 103a each have a groove formed by recessing the upper surface portion. The groove portion is disposed in the lateral direction (a direction crossing each shift fork), and both end portions are open. The groove portion has a substantially rectangular cross-sectional shape and accommodates the forward engaging portion 123 of the arm shifter 120 when engaged. In the neutral state, the groove portions of the shifter engaging portions are arranged so that their positions in the front-rear direction (the rotation axis direction of the manual transmission 1) are substantially coincident. In the neutral state, the forward engagement portion 123 is accommodated in the groove portion of the 3-4 speed shifter engagement portion 112a.

The reverse engagement portion 124 is a protrusion that protrudes from the side surface portion of the arm portion 122 at the intermediate portion between the shaft portion 121 and the forward engagement portion 123 toward the reverse shifter engagement portion 114a.
As shown in FIG. 2, the reverse shifter engaging portion 114 a is formed so as to protrude downward from the rear end portion of the reverse fork rod 114 in a tab shape, and is arranged to face the side surface portion of the arm portion 122. The reverse shifter engaging portion 114a is formed with a recess that engages with the reverse engaging portion 124. The recess is formed by recessing the lower end of the reverse shifter engaging portion 114a upward, and is formed as a groove that penetrates the reverse shifter 114a in the thickness direction. The cross-sectional shape of the groove when viewed from the direction in which the reverse engaging portion 124 is inserted is substantially rectangular.
The reverse shifter engaging portion 114a is the forward shifter engaging portion in the outermost row at the position in the arrangement direction of the forward shifter engaging portions (the horizontal direction in FIG. 3 and the direction perpendicular to the paper surface in FIG. 2). It is arranged at a position overlapping with the 5-6 speed shifter engaging portion 103a. That is, the reverse shifter engaging portion 114a is disposed above the 5-6 speed shifter engaging portion 103a.

Next, the operation of the shift operation unit 100 when the manual transmission 1 is shifted will be described.
First, the shift from neutral to sixth gear will be described.
FIG. 6 is a side view of the speed change operation device 100 and shows a state where the sixth speed is selected.
FIG. 7 is a view of the engaging portion between the arm shifter and the fork rod as viewed from the rear, and shows a state where the sixth speed is selected.
FIG. 8 is a perspective view of the speed change operation device 100 and shows a state where the sixth speed is selected.

  First, the driver performs a selection operation by pushing the shift knob 203 to the left from the neutral position without operating the slider 204. The arm shifter 120 performs a selection operation that swings clockwise in FIG. 3 around the axis of the shaft portion 121 in accordance with the selection operation of the driver. Then, by swinging the shift lever 202 until the reverse check member 205 hits the wall portion 201 a, the forward engagement portion 123 of the arm shifter 120 is moved to the 5-6 speed shifter engagement portion 103 a of the 5-6 speed shift fork 103. The selection of the 5-6 speed shift position is completed.

  Next, the driver performs a shift operation by retracting the shift knob 203. The arm shifter 120 performs a shift operation that moves backward along the axial direction of the shaft portion 121 in accordance with the shift operation of the driver. At this time, the forward engaging portion 123 pushes the rear surface of the groove portion of the 5-6 speed shifter engaging portion 103a, thereby pulling the 5-6 speed shift fork 103 rearward and retracting it. As a result, the 5-6 speed hub sleeve 43 moves backward to fix the 6 speed drive gear 16 to the drive shaft 2 to complete the 6 speed gear train. As a result, the drive shaft 2 and the driven shaft 3 can transmit power via a 6-speed gear train.

Next, the shift from neutral to reverse will be described.
FIG. 9 is a view of the shift operation device 100 as viewed from the side, and shows a state in which reverse is selected.
FIG. 10 is a view of the engagement portion between the arm shifter and the fork rod as viewed from the rear, and shows a state in which reverse is selected.
FIG. 11 is a perspective view of the speed change operation device 100 and shows a state in which reverse is selected.

First, the driver performs a selection operation by pushing the shift knob 203 to the left while the slider 204 is pulled up. At this time, the reverse check member 205 gets over the wall 201a, and the shift lever 202 swings to the select position corresponding to the reverse.
As a result, the reverse engagement portion 124 of the arm shifter 120 is inserted into the recess of the reverse shifter engagement portion 114a and engaged with the reverse shifter engagement portion 114a, and the selection of the reverse shift position is completed.

  Next, the driver performs a shift operation by retracting the shift knob 203. The arm shifter 120 performs a shift operation that moves backward along the axial direction of the shaft portion 121 in accordance with the shift operation of the driver. At this time, the reverse engaging portion 124 pulls the reverse shift fork 104 backward by pushing the rear surface of the concave portion of the reverse shifter engaging portion 114a, and moves it backward. As a result, the reverse coupling sleeve 33 moves backward to connect the first reverse idler gear 31 and the second reverse idler gear 32 to complete the reverse gear train. As a result, the drive shaft 2 and the driven shaft 3 can transmit power via the reverse gear train.

An interlock plate 50 described below is provided on the inner surface of the transmission case (not shown).
The interlock plate 50 is, for example, a steel plate disposed adjacent to the surface portion of the reverse shifter engaging portion 114a opposite to the arm shifter 120. When the reverse shifter engaging portion 114a is pressed by the arm shifter 120, the interlock plate 50 comes into contact with the reverse shifter engaging portion 114a and restricts its displacement.

In the following, a method for connecting a selector cable, which is a select operation transmission member that transmits the select operation input to the shift lever 202 to the arm shifter 120 in the shift operation device of the present embodiment, will be described.
First, before connecting the selector cable, the arm shifter 120 is operated using a tool or the like, and the manual transmission 1 is shifted to the sixth speed. As a result, as shown in FIG. 7, the reverse engaging portion 124 of the arm shifter 120 does not engage with the concave portion of the reverse shifter engaging portion 114a, but abuts against and presses the surface portion adjacent to the concave portion. . By this pressing, the reverse shifter engaging portion 114 a is displaced around the central axis of the reverse fork rod 114 in the clockwise direction in FIG. 7 and comes into contact with the interlock member 50. At this time, the reverse shifter engaging portion 114 a is positioned between the reverse engaging portion 124 of the arm shifter 120 and the interlock member 50.
Next, in the shift lever unit 200, the shift knob 203 is pushed to the left without lifting the slider 204, and is further moved backward to a position corresponding to the sixth speed.
In this state, the select cable and the shift cable that connect the shift operation device 100 and the shift lever unit 200 are connected.

  According to the embodiment described above, when the shift to the 6th speed at the select position adjacent to the reverse select position is performed, the reverse shifter engaging portion 114a is connected to the reverse engaging portion 124 and the interface of the arm shifter 120. Since the shift lever 202 is shifted to the sixth speed in order to be positioned by being sandwiched between the lock plates 50, the select cable is connected so that the select position of the shift operation device 100 and the shift lever unit 200 can be accurately aligned. And it can be done easily.
