Description

[Detailed Description of the Invention] The present invention provides a speed change operation device for an automobile, specifically a change lever, and a control rod, and the control rod is disposed within a floor tunnel formed by bulging upwards within the floor tunnel. The present invention relates to a speed change operation device that is efficient.

Generally, the floor panel of a car body, particularly a front engine, front drive car, has a floor tunnel that bulges out upwards from the panel in the front-rear direction of the car body, and a floor tunnel is provided in the front-rear direction of the car body. A control rod and exhaust pipe are installed.

On the other hand, the control rod is a double type that uses two control rods, a shift iron and a select rod, and a single control rod that has movement in the longitudinal direction of the vehicle body and rotational movement. A single type is known that allows shift operations and selection operations to be performed.

However, with the double type, the number of parts increases, and it takes up a lot of space inside the tunnel.
It was necessary to increase the size of the floor tunnel,
In addition, in the single type, a control rod is connected to a position below the pivot point of the change lever to the vehicle body to give rotational movement to the rod, so that the change lever is rotated in the select direction. The rotational movement of the control rod that is operated by operation is a swinging rotation about the pivot center, and therefore requires a space in the control rod that is larger than the swinging range of the control rod. There was a problem that the width of the tunnel became that much larger.

The present invention was devised in view of the above-mentioned conventional problems, and the purpose is to provide a speed change operation device that can minimize the size of the tunnel, and the lower end of the change lever is , the rear end portion of the control rod is rotatably supported on the vehicle body at approximately the same height as the tunnel height, and the front end of the control rod is supported on the vehicle body so as to be movable and rotatable in the longitudinal direction. The control rod is curved and pivotally connected to the change lever at a position above the rotation center of the change lever, while the rotation center position of the control rod and the rotation center position of the change lever are at approximately the same height position. This feature is characterized by the fact that they match.

Embodiments of the present invention will be described below based on the drawings.

1 is a change lever; 2 is a housing having a support 3 that supports the change lever 1 on a floor panel F so that it can be operated in the longitudinal direction and the vehicle width direction; 4 is pivotally connected to the change lever 1; Al with control rod.

The change lever 1 has a grip 11 at one end and a sphere 12 at the other end, and the sphere 12 is inserted into the support 3 and supported so as to be rotatable.

That is, the support 3 includes a pair of sheets 32, 32 each having a spherical inner surface that contacts and supports the spherical body 12 in a bottomed cylinder 31.
A screw body 34 is screwed onto the open side of the cylindrical body 31 and fixed with a lock nut 35 to support the sphere 12 under a predetermined friction.

The housing 2 also includes a strength member 2 cut out from a metal plate.
1 and a rubber cover 23 that is fixed to the member 21 via a presser foot 22, and the support 3 is fixed to the member 21, and the fixing position of the support 3 is the housing 2. When attaching the change lever 1 to the floor panel F, the lower end of the change lever 1 supported by the support 3 is placed at a position approximately at the same height as the top surface height of the floor tunnel T provided on the panel F, and the lower end of the change lever 1 supported by the support 3 is placed approximately at the height of the tunnel T. They are fixed at the same height, that is, slightly lower than the top surface height under the floor tunnel.

The control rod 4 has its front end supported by a bracket 5 fixed to the front frame so as to be movable and rotatable in the longitudinal direction of the vehicle body, and its rear end is curved upward to accommodate this curve. The end 4a is connected to the change lever 1
The change lever 1 is pivotally mounted 6 to the change lever 1 at a position above the rotation center 01 about the spherical body 12 .

The front end of the control rod 4 is connected to the front end of the control rod 4 via a bell crank-shaped shift lever 41 swingably supported by the bracket 5 via the vertical shaft 7, and a universal joint 8 supported by the shift lever 41. It is supported by a bracket 5 so as to be movable and rotatable in the front and rear directions of the vehicle body.

In other words, the rotation center 02 of the control rod 4, which is rotatably supported via the joint 8, is at the same height as the rotation center 01 of the change lever 1. It matches the position.

Therefore, when the change lever 1 is rotated in the vehicle direction, that is, in the Sereno I direction, the control rod 4
The control rod 4 rotates at the same position about the axis connecting the rotation centers 01 and 02, and the control rod 4 does not swing in the left-right direction.

The universal joint 8 is located at the same tank bottom as the support 3 of the change lever 1.

That is, the shift lever 41 has a short shaft 82 having a sphere 81.
A bottomed cylindrical body 83 is fixed to the front end of the control rod 4, and a pair of seats 84, 8 are placed inside this cylindrical body 83.
4 and a spring 85 inside, and the cylindrical body 83
A screw body 86 is screwed onto the open side of the tank and fixed with a lock nut 87 to form the bottom of the tank.

Further, in FIGS. 1 and 2, 42 is the shift lever.
41 is a shift rod pivotally connected to the cylindrical body 83 of the universal joint 8; 44 is a select lever fixed to the cylindrical body 83 of the universal joint 8;
It is a select rod that connects via.

Further, in FIG. 1, reference numeral 9 denotes a boot made of a flexible material such as rubber.

10 also connects the control rod 4 to the tunnel T.
An exhaust pipe disposed together with the exhaust pipe 10,
As shown in FIGS. 1 and 3, the width of the tunnel T can be further reduced by positioning it below the rod 4 and arranging the rod 4 and the exhaust pipe 10 one above the other.

At the bottom of the tank, change the change bar 1 to the sphere 1.
When the vehicle body is rotated in the vehicle width direction about 2, the upwardly curved rear end of the control rod 4 swings, and the rod 4 rotates about the axis connecting the rotation centers 01 and 02. When the change lever 1 is rotated in the longitudinal direction of the vehicle body, the control rod 4 is moved. ,
A shift operation is performed by moving the shift lever 41 in the front-rear direction, swinging the shift lever 41 about the vertical axis 7, and reciprocating the shift rod 42 connected to the shift lever 41.

As described above, in the present invention, the rear end of the control rod is curved upward and is pivotally connected to the change lever at a position above the rotation center of the change lever, so that the rotation center position of the control rod and the change lever are Since the rotation center positions are aligned with each other, when the change lever is rotated in the vehicle direction, that is, in the select direction, the control rod rotates about an axis connecting the rotation centers,
The change lever can be rotated at the same position without wobbling, and therefore the width of the floor tunnel in which the control rod is placed can be reduced.Moreover, the lower end of the change lever can be placed at approximately the same height as the floor tunnel. Since it is positioned and supported, the height of the tunnel can also be reduced.

Moreover, since the control rod rotates at the same position without swinging around the axis, when the change lever is operated in the select direction, the connecting portion of the rod to the change lever is not strained and the connection is smooth. This allows rotational operation, improving operability and improving durability.
