Description

  The present invention relates to a manual transmission mounted in an automobile, and belongs to the technical field of an automobile transmission.

  A manual transmission mounted on an automobile is provided with a plurality of gear trains having different gear ratios between an input shaft connected to an engine via a clutch and an output shaft connected to a drive wheel, and a change lever is selected. A plurality of forward shift stages and one reverse shift stage are achieved by selectively setting one of the plurality of gear trains in a power transmission state in accordance with an operation and a shift operation. It has become.

  In a vertical-type manual transmission mounted on an automobile such as a front engine or a rear drive vehicle, a control rod connected to the change lever is rotated by a select operation of the change lever, and a plurality of shift rods are selected. Select one of the shift rods, then move the control rod in the axial direction by shifting the change lever to move the selected shift rod to one side or the other side in the axial direction of the shift rod and select The desired gear stage is achieved by using the gear stage for the changed gear stage as a power transmission state.

  Conventionally, the change lever is supported by the rear end portion of the transmission case, extends through the tunnel portion provided in the center of the vehicle body floor in the vehicle width direction, extends into the passenger compartment space, and is attached to the front end portion of the change lever. A knob is provided on the side of the driver's seat.

  By the way, when a manual transmission is shared in an automobile having different vehicle types such as a sports type, a sedan type, and an SUV (sports multipurpose vehicle) type, the position of the change knob is located on the side of the driver's seat in an automobile of a certain vehicle type. Even if properly positioned, the position of the change knob may be inadequate for other vehicle types of cars.

  For example, when a manual transmission mounted on a sports type vehicle with a low seating position of the driver seat is mounted on an SUV type vehicle with a high seating position of the driver seat, the SUV type vehicle is seated on the driver seat. The position of the change knob is lowered for the driver.

  On the other hand, it is possible to adjust the change knob position by changing the length of the change lever, but the distance from the fulcrum of the change lever to the connecting part with the control rod and from the fulcrum of the change lever to the change knob. Since the lever ratio, the change stroke, and the change lever, which are ratios to the distance, change, the operation feeling can be adversely affected.

  In addition, it is conceivable to change the position of the change knob without changing the configuration of the change lever or the lever ratio of the change lever by tilting the control rod extending in the longitudinal direction of the vehicle body with respect to the axis of the manual transmission, When tilting the control rod, it may be possible to tilt the control rod on the axis via a joint, but if the tilt angle of the control rod increases, the link efficiency will deteriorate, so the operation feeling of the change lever may deteriorate. There is.

  In view of this, in a vertical manual transmission, it is conceivable to change from a direct type in which the change lever is directly connected to the control rod to a cable type in which the change lever and the control rod are connected via a cable.

  Patent Document 1 discloses a cable-type manual transmission. As shown in FIG. 7, in this manual transmission 100, a select lever 103 that moves the control rod 102 in the axial direction is connected to a control rod 102 that performs a shifting operation in a transmission unit 101 that is disposed above the manual transmission. A shift lever 104 that rotates the control rod 102 about its axis is engaged.

  In addition, a select link 106 and a select lever 103 that are slidably disposed in conjunction with a select operation of the change lever 105 are connected via a select operation cable 107, and in conjunction with a shift operation of the change lever 105. A shift link 108 and a shift lever 104 that are swingably disposed are connected via a shift operation cable 109.

  When the change lever 105 is selected, the control rod 102 is moved in the axial direction via the select link 106, the select operation cable 107, and the select lever 103. When the change lever 105 is shifted, the shift link 108 and the shift operation cable are moved. The control rod 102 is rotated via the shift lever 104 and the shift lever 104, whereby the operation of the change lever 105 is transmitted to the control rod 102 via the cables 107 and 109 to perform a shift operation.

  In the manual transmission 100 described in Patent Document 1, the change lever 105 and the control rod 102 are connected via cables 107 and 109, so that the change lever 105 can be connected to the change lever 105 without changing the lever ratio. It is possible to set the position of the attached change knob 110 to an appropriate position according to the vehicle type or the like.

  By the way, when the change lever and the control rod are connected via a cable in the vertical manual transmission as in the manual transmission described in Patent Document 1, the change lever is a shift in which the control rod is accommodated. Since it is separated from the machine case, the change lever is necessarily supported by the vehicle body.

  However, when the change lever is supported by the vehicle body, relative displacement occurs between the manual transmission and the change lever due to vibrations caused by a driving source such as engine torque fluctuation.

  On the other hand, as in the manual transmission described in Patent Document 1, the cable is extended as much as possible by extending the cable connected to the change lever to the front side of the vehicle and then making a U-turn to connect it to the speed change operation mechanism. Thus, it is possible to absorb the relative displacement between the manual transmission and the change lever due to vibration of the drive source or the like.

  However, when the cable connected to the change lever is lengthened to absorb the relative displacement between the manual transmission and the change lever, the space required for installing the lengthened cable becomes large and the manual transmission Since the tunnel portion in which the vehicle is stored becomes large, the passenger compartment space can be narrowed and the comfortability of the passengers can be reduced. In particular, in an automobile equipped with a vertical-type manual transmission, such a problem may become more conspicuous because the cabin space is narrowed by the tunnel portion.

  Therefore, the present invention can be applied to a vehicle of a type in which the position of the change knob is different, and an object of the present invention is to provide a manual transmission that suppresses a decrease in occupant comfort.

The support portion is provided on a side of the transmission case, and the connecting portion with the cable in the speed change operation mechanism is provided on one end side in the vehicle longitudinal direction of the transmission case with respect to the change lever.

  With the above configuration, according to the first aspect of the present invention, since the change lever and the speed change operation mechanism are connected by the cable, the operation of the change lever is transmitted to the speed change operation mechanism through the cable, The mechanism is in a state where a desired gear stage can be obtained. Since the cable is interposed, the position of the change lever can be set freely with respect to the manual transmission mounted at a predetermined position. The position can be appropriately set according to the vehicle type.

  At that time, since the change lever is supported by a support portion provided in the transmission case, the change lever is not supported between the manual transmission and the change lever due to vibration caused by a drive source as in the case where the change lever is supported by the vehicle body. Relative displacement can be suppressed.
