Abstract

PURPOSE:To attain the accurate remote control of a transmission by transmitting the shift and selection direction operations to a control lever to a shifter rod through the push-pull action of an inner cable and the twist direction angles of both an outer tube and the inner cable respectively. CONSTITUTION:When a control lever 1 is operated in the shift direction, i.e., in the front-back direction of a vehicle body, the lever 1 is turned round a shaft 5 and causes a push-pull action to the an inner cable 61 connected to a cable connection part 1a set at the lower end of the shaft 5 via a pin at an end part of the cable 61 in the axial direction. Thus the cable 61 moves accurately a shifter rod 71 of a transmission 7 in the axial direction by means of said push-pull action. Thus the transmission 7 has a shift action. When the lever 1 is operated in the selection direction, i.e., in the width direction of the vehicle body, the lever 1 is turned in a body with a selection direction rotary member 3 centering on a shift 4. While an arm pat 32 and a cable attachment tool 33 are oscillated right and left centering on the shaft 4. Then the selection direction operation of the lever 1 actuates the rod 71 in its revolving direction via the twist direction displacements of an outer tube 62 and the cable 61.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a remote control device for a vehicle transmission. ・Conventional technology As a remote control device for a vehicle transmission, the present invention relates to a shift direction operation and a select direction operation of a control lever. Various cable-type remote control devices have been developed in the past that transmit operations to the transmission side using a shift cable and a select cable, respectively (for example, Utility Model No. 57-14712
(See Publication No. 0).

Problems to be Solved by the Invention As described above, the cable-type remote control device using two cables, the shift cable and the select cable, is capable of controlling both the shift direction and the select direction of the control lever. On the other hand, for example, a lever mechanism must be provided on a part of the operating lever to convert the operation in the select direction into movement in the axial direction of the select cable, which not only complicates the structure and increases the size of the operating lever assembly, but also increases the size of the select cable. A lever mechanism must be installed on the transmission side that converts the axial movement of the cable into rotational movement of the shifter rod of the transmission, making the structure of the transmission complex and large, with a large number of parts, making it expensive, etc. I have this problem.

In order to solve the above-mentioned problems with cable-type remote control devices, it is natural to use a bush blue torsion cable that can transmit operating force by pushing and pulling in the axial direction and twisting with a single cable. However, since the flexible inner cable that transmits the operating force is fitted and guided within an outer tube that has a certain degree of rigidity, the operating force in the push and pull directions can be sufficiently transmitted, but the rigidity in the torsional direction is We have specially manufactured a special push-pull torsion cable with extremely high torsional rigidity of the inner cable, which is generally extremely low and it is impossible to transmit the torsional operating force through the inner cable with ordinary cables. Naturally, if you try to use this, the cost will be significantly higher than when using a commercially available cable.

The main object of the present invention is to provide a remote control device for a transmission that can solve all of the conventional problems as described above.

Means for Solving the Problems The present invention provides a remote control device for a vehicular transmission, in which a member comprising an outer tube and an inner cable serves as a member for transmitting the rotational operation of a control lever to a shifter rod of the transmission.
Using a push-pull cable, the operation of the operating lever in the shift direction is transmitted to the shifter rod through the push-pull operation of the inner cable, and the operation of the operating lever in the select direction is transmitted to the shifter rod through the torsional angular displacement of the outer tube and inner cable. The present invention is characterized in that it has a configuration in which:

Effect As described above, during shift operation, the inner cable is fitted and supported within the relatively rigid outer tube, so
The inner cable is actuated precisely in the push-pull direction based on the rotational operation of the control lever to actuate the shifter rod in the axial direction, thereby performing a shift operation of the transmission. Furthermore, during select operation, the shifter rod is rotated about its center line mainly by the angular displacement in the torsional direction of the outer tube, which has high torsional rigidity, and the angular displacement in the torsional direction of the inner cable is caused by the rotational movement of the shifter rod by the outer tube. It provides an auxiliary force to accurately select the transmission.

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

In FIGS. 1 and 2, reference numeral 1 indicates an operating lever provided in the vehicle interior, and reference numeral 2 indicates a bracket attached to a vehicle body member such as a floor panel 11. The selection direction rotating member 3 is attached to the shaft 4 of the bracket 2. It is rotatably attached to the shaft. The select direction rotating member 3 has an operating lever shaft attachment portion 3 for pivoting the operating lever l so as to be rotatable in the shift direction.
A substantially cylindrical cable fitting 33 for attaching and supporting one end of a push-pull cable 6 (to be described later) is attached to the arm portion 3.
By pivoting the intermediate portion of the operating lever 1 to the operating lever pivoting portion 31 of the select direction rotating member 3 via the shaft 5, the operating lever can be rotated. l can be rotated about the shaft 5 in the shift direction, that is, the longitudinal direction of the vehicle body, and can be rotated together with the select direction rotation member 3 about the shaft 4 in the select direction, that is, the width direction of the vehicle body. ing.

In the assembled state of the operating lever 1 as shown in , the cable connecting portion 1a at the lower end of the operating lever 1 is located on the rearward extension of the center line of the cable fitting 33.

6 is a push-pull cable consisting of an inner cable 61 and an outer tube 62 that fits and supports the inner cable 61, and one end of the push-pull cable 6 is
Outer tube 6? Attach the end of the inner cable 61 to the cable fitting 33 by caulking or the like, pass the end of the inner cable 61 through the cable fitting 33, and insert the cable end rod 61a into the cable joint 1a of <-1. Push-pull cable 6 by pin-coupling
is connected to an operating section assembly consisting of an operating lever 1 and a select direction rotating member 3.

A bracket 9 is attached to the case of the transmission 7, and a cylindrical rotating member 8 having a hollow cylindrical shape is mounted on the bracket 9, and a bearing 10 is mounted on the bracket 9 in such a manner that its center line is located on an extension of the center line of the shifter rod 71. The outer tube 62 end of the push-pull cable 6 is fitted into the cylindrical rotating member 8 by caulking or the like, and the inner cable 61 end is attached to the cylindrical rotating member 8 so as to rotate around its center line. It passes through the center of the shaped rotating member 8 and is pin-coupled to the shifter rod 71 of the transmission 7 via a cable end rod 61b. An arm member 72 is integrally fixed to the shifter rod 71, and the protrusion 8a of the cylindrical rotating member 8 engages with the retaining portion 72a of the arm member 72 in the rotational direction, so that the rotation of the cylindrical rotating member 8 is prevented. The signal can be transmitted to the shifter rod 71 through the arm member 72.

In the above, when the operating lever 1 is operated in the shift direction, that is, in the longitudinal direction of the vehicle body, the operating lever 1 rotates around the shaft 5, and the inner cable 61, whose one end is pin-coupled to the cable coupling part 1a at the lower end, is pivoted. Push and pull in the direction.

Since the inner cable 61 is fitted and guided within an outer tube 62 which has a certain degree of rigidity and flexibility, the shifter rod 71 of the transmission 7 can be accurately moved in the axial direction by the above-mentioned axial pushing and pulling operation. Then, the transmission 7 is shifted.

When the operating lever l is operated in the selection direction, that is, in the vehicle width direction, the operating lever l rotates around the shaft 4 together with the selection direction rotating member 3, and the arm portion 32 and the cable attachment 33 rotate around the shaft 4. It swings left and right around the center. The maximum swing angle is regulated by the left and right side edges of the window hole 2a formed in the bracket 2.

Since one end of the outer tube 62 is fixed to the cable fitting 33 by caulking or the like, the one end of the outer tube 62 swings from side to side integrally with the cable fitting 33 and undergoes angular displacement in the direction of rotation. do. As mentioned above, the outer tube 62 generally has a certain degree of rigidity, and its torsional rigidity is much higher than that of the inner cable 61.
The angular displacement in the rotational direction (torsional direction) caused by the left and right rocking of one end as described above is accurately transmitted to the cylindrical rotating member 8 to which the other end of the outer tube 62 is fixed. 8 rotates about its center line, and the rotation is transmitted from the arm member 72 to the shifter rod 71 due to the engagement between the protrusion 8a and the engaging portion 72a, and the shifter rod 71 rotates to rotate the transmission 7. In this case, when the operating bar 1 is rotated in the select direction, one end of the inner cable 61, which is pin-coupled to the cable coupling part 1a at the lower end of the operating lever 1, also rotates from left to right like the outer tube 62 shown in L. Although the inner cable 61 is said to have considerably lower torsional rigidity than the outer tube 62,
The angular displacement is transmitted to the shifter rod 71 to which the other end of the inner cable 61 is pin-coupled, and somewhat assists the selection operation by the outer tube 62, thereby preventing the inner cable 61 from twisting and deforming with respect to the outer tube 62. This is not the case at all, and the shift operation after the selection operation can be performed accurately.

FIG. 3 shows another embodiment of the present invention. In this example, the center of the shaft 4, which is the center of rotation of the selection direction rotating member 3, and the center of the cable attachment 33 are located on the same line. - When operating the operating lever 1 in the select direction, the cable fitting 33 and the inner cable 61. The only difference from the embodiment shown in FIG. 1.2 is that one end of the outer tube 62 is angularly displaced (rotated) in the torsional direction about their center line without swinging left and right. The structure other than the above is the same as that in Figs. 1 and 2, and the same symbols as in Figs.
It is the same as the one shown in the figure.

Effects of the Invention As described above, according to the present invention, in a remote control device for a transmission, the inner cable can be moved in the axial direction within the outer tube as a member for transmitting the rotational operation of the control lever to the shifter rod of the transmission. Using one push-pull cable that is fitted and supported so that the operating force of the operating lever in the shift direction is transmitted to the shifter rod by the push-pull operation of the inner cable, the operating force of the operating lever in the select direction is transmitted between the outer tube and the inner cable. By adopting a structure in which the information is transmitted to the shifter rod by the angular displacement in the torsional direction, the number of parts is reduced and the device is significantly smaller compared to the conventional system that uses two cables: a shift cable and a select cable. It is possible to reduce the size and weight of the cable, and also to reduce the space required for running the cable.Furthermore, since the selection direction operation force is transmitted primarily through the outer tube, which originally has high torsional rigidity, it is possible to reduce the cable routing space. Since the current push-pull cable, which is generally reprinted from the past without requiring a cable structure, can sufficiently achieve the desired purpose, the cost is extremely low, and it can bring about a significant overall cost reduction, making it practical. This can bring about great effects.
