Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tilt steering remote control device that is attached to a tilt-operable steering wheel and transmits a driver's gear change operation to a transmission.

2. Description of the Related Art Tilt operating devices are used in which the steering handle can be oscillated to accommodate drivers of various physiques or for various driving postures.

This steering wheel with tail operation device has a transmission mechanism that transmits the driver's gear change operation to the transmission, that is, a remote control transmission (hereinafter referred to as a "remote control device").
) is installed, various problems may occur.

In other words, the upper part of the remote control device is attached to the steering support device that supports the steering shaft, and the lower part is attached to the vehicle body by a spherical bush, etc., so the remote control device also swings according to the tilt operation, but the steering and IJ control device The centers of oscillation are at different points.

This is particularly noticeable when the steering wheel has its center of swing near the driver's hand. Due to this difference in the center of swing, the shift lever, which is attached to the bottom of the remote control and transmits the driver's shift operation to the shift link connected to the transmission, moves during tilt operation, making it appear as if the driver were shifting. There are cases where the same movement is made.

In addition, due to the difference in the center of swing, the steering support device and remote control device become in a so-called link interference state, and a force is applied in the direction of the remote control device, so when the tilt operation is performed, the remote control device moves toward the bag, causing the control lever to move to the neutral position. The position will change.

It is therefore an object of the present invention to provide a remote control device for tilt steering that does not cause the disadvantages of the prior art, namely, shifting operations and driving sensations.

The tilt steering remote control device according to the present invention includes:
The connection between the shift lever and shift link is the center of swing of the control shaft, the upper shaft is pivotally supported on the steering support member via a spherical bushing, and the upper shaft is moved in all directions by a guide groove during tilt operation. This is to absorb so-called link interference and achieve the intended purpose.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the remote control device 10 has an axial center A of a steering support portion 12 and an inclined axial center B.
6 and the lower control shaft 18 constitute its main part. This Atsupa control shaft 1
6 and the lower control shaft 18 are coaxially molded, and are designed to contract in the axial direction together with the steering support village 12 to absorb the collision load on the driver's steering wheel 20 only in a dangerous situation such as a vehicle collision. It has become. As shown in FIG. 2, a hollow hole 22 is bored from the lower end of the lower control shaft 18, and within this hollow hole 22 is a ball bearing 28 attached to a bracket 26 protruding from the vehicle body 24. It's rushing in.

This ball bearing 28 is covered with a concave ball bushing 30 which is iron-fixed in the hollow hole 22, thereby making the control shaft 18 swingable about a swing center line C passing through the center of the ball bearing 28. . A shift lever 32 is fixed to the outer periphery of the control shaft 18, and a spherical protrusion 38 of a shift link 36 to which a shift operation of the control shaft 18 is transmitted via a ball washer 34 is attached to a part of the shift lever 32. is iron-filled.

Therefore, the shift operation of the control shaft 18 (wistling rotation of the control shaft 18) is performed by the shift lever 32.
, is transmitted as a movement of the control shaft 18 in a direction perpendicular to the plane of the paper via the spherical protrusion 38, thereby performing a speed change operation of a transmission (not shown). Here, the center of the spherical protrusion 38 that is the connecting part between the shift lever 32 and the shift link 36 is provided on the swing center line C of the control shaft 18, and the control shaft 18 is centered around the ball bearing 28 by tilting the steering wheel. The shift link 34 does not move in the shift direction even when the shift link 34 swings as shown in FIG.

An annular groove 40 is formed around the axis of the control shaft 18 in a part of the shift lever 32, and one end 4 of the select lever 42, which is pivotally supported by the bracket 26, is formed in a part of the shift lever 32.
4 is competing.

A select link (not shown) is connected to the end 46 of the select lever 42 so that the select operation of the control shaft 18 (movement of the control shaft 18 in the direction of the ball) is transmitted to the transmission after a rocking motion about a rocking center 47. It has become. Next, a hollow hole 50 is bored in the upper end of the upper control shaft 16 which is integrated with the lower control shaft 18 by molding, and one end of the upper shaft 14 is inserted into this hollow hole 50. This tip and hollow hole 50
A compression coil spring 52 is interposed between the bottom portions of the springs.

Further, from the center of the upper shaft 14 to the end of the shaft is a pongee portion 56 with a stepped portion 54 as a boundary, and the center portion of this thin and light portion 56 is connected to the upper shaft fixed to the steering support member 12 via a spherical bush 58. It is supported by the bracket 60, and the tip end 57 passes through the spherical bush 58 and projects toward the steering wheel 20.

Here, the upper shaft 14 has a stepped portion 54 and a spherical bush 5.
A compression coil spring 66, which is weaker than the spring 52, is interposed between the spherical bush 58 and the spherical bush 58 to press the convex spherical surface of the spherical bush 58 against the concave spherical surface of the upper bracket 60.

In addition, the Atsupa shaft 14 has a pin 67 perpendicular to its axis.
passes through the upper bracket 6, and this pin 67 is positioned within an arcuate guide 68 formed in the upper bracket 6.

As shown in FIG. 3, this guide 68 is a circular arc whose center of rotation is above the steering wheel, that is, in the direction of the steering wheel 20. As a result, when the driver moves the steering wheel 20 in the direction away from the driver (see FIG. 1 20A) during the tail operation, the upper shaft 14 is pulled toward the upper bracket 60,
By this reverse tilt operation (see FIG. 1 20B), the upper shaft 14 is moved to the control shaft 16 in the opposite direction to that described above.
It is designed to be pressed down in the direction. Furthermore, this guide 6
The above effect can be achieved even if the groove 8 is a straight groove instead of an arcuate groove.

The guide 68 is attached to the holding plate 6 after the pin 67 is inserted.
The pin 67 is prevented from falling off by fixing the pin 9 to the attachment bracket 60 through the mounting bolt 7.

Next, the upper shaft 14 located in the hollow hole 50 has a tip ball portion 7 which is the rotation center of the control lever 72.
A substantially cylindrical through-support hole 76 into which 4 is inserted with iron is bored perpendicular to the axis.

A spherical acting portion 78 is located near the tip spherical portion 74 of the control lever 72, which has the tip spherical portion 74 inserted into the support hole 76.
The working part 78 is supported through a bush 80 in a tube 82 which projects from the control shaft 16 at right angles.

In addition, the control lever 72 is extended from the operating portion 78 by a considerable amount, and then a shift knob 84 is covered with the control lever 72 to serve as a gear shift operation input section for the driver. 16 in the ball direction or in the rotating direction, the gear selection and shift operations can be performed using the action.

Furthermore, these speed change operations are performed using the lower control shaft 1.
The shift operation, that is, the rotation of the control shaft 18 around its axis, is transmitted to the shift lever 32 by pulling the shift link 36 through the spherical protrusion 38 (in the direction perpendicular to the plane of the paper in FIG. To move in the direction of the ball, use the select lever 42.
Swing center 47 from annular groove 40 added to one end 44
The rotational vibrations are transmitted to the transmission. Next, the steering handle 2
0 is moved together with a part of the steering support village 12 by a tilt mechanism (not shown) (two-dot chain line in FIG. 1)
The operation of the remote control device will be explained below.

By tilting the steering wheel, the remote control device 10 is also tilted according to the movement of the upper bracket 60.

However, unlike in the past, the spherical protrusion 38 that connects the shift lever 32 and the shift link 36, which are fixed to the lower control shaft 18, is located on the swing center line C of the control shaft 18, so it may shift accidentally during the tilt operation. There is no risk of manipulation. Furthermore, the so-called link interference caused by the difference in the swing centers of the remote control device 10 and the steering wheel 20 is caused by the pin 67 of the atspa shaft 14 moving towards the guide 68 as the steering wheel is tilted.
Since the remote control device slides inside and moves in the direction of the ball, the axial length of the remote control device can be adjusted as appropriate, and there is no possibility of IJ link interference.

Note that this link interference must be appropriately corrected (it is necessary to determine the shape of the guide 68 in advance). Of course, it is also possible to provide the pin 67 on the upper bracket 60 and form the guide 68 on the upper shaft 14. Further, the swinging angular displacement between the remote control device 10 and the steering support member 12 is absorbed by the convex spherical surface of the spherical bushing 58 causing an angular displacement with the concave spherical surface of the upper placket 60.

With the above-described configuration, the remote control device according to the present invention has an excellent effect in that even in the tilt operation of the steering wheel, there is no erratic operation or disturbance of the driving sensation.
