Abstract

PURPOSE:To maintain the shift feeling optimum and improve the durability of a vibrationproof rubber by forming an upper lever with a soft member in a gear shift lever or the like of an automobile. CONSTITUTION:A vibrationproof rubber 2 is coupled and fixed on the upper end outer periphery of a lower lever 1, and the cylindrical lower section of an upper lever 3 is coupled and fitted on its outside. The upper lever 3 is made of resin as a soft member, and a shift knob section 7 inserted with a weight 6 is integrally molded on the upper end. When a crew operates the upper lever 3, its shock is absorbed by the vibrationproof rubber 2 and also absorbed by the bending deformation of the upper lever 3 molded with resin itself. Part of the load primarily applied to the vibrationproof rubber 2 having low rigidity in the P1 direction to improve the shift feeling is shared by the upper lever 3, and the durability of the vibrationproof rubber 2 can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to control levers such as gear shift levers of automobiles.

An example of a conventional vehicle wheel lever is shown in FIG. 7.

In FIG. 7, a vibration isolating rubber 2 is attached to the outer periphery of the upper end of a lower lever 1 that is linked to a transmission (not shown), and the vibration isolating rubber 2 is received from the outside.
A cylindrical lower part of a metal upper lever 3 is attached to the upper end of the lever. The vibration isolating rubber 2 is an annular member that is fitted and fixed to the lower lever 1, and serves to absorb the impact force applied when the upper lever 3 is moved and to prevent vibrations from being transmitted from the transmission.

A threaded portion 4 is provided at the upper end of the upper lever 3, and a shift knob 5 is attached to this threaded portion 4 (see, for example, Japanese Patent Laid-Open No. 123919/1983).

Problems to be Solved by the Invention The vibration isolating rubber 2 may be made to have its rigidity in the P direction shown in FIG. 7 reduced in order to improve the soft feeling. There is a problem that durability is reduced, such as cracks becoming more likely to occur.

Therefore, the present invention provides a control lever that can improve the durability of the vibration isolating rubber while optimally maintaining a soft feeling.

Means for Solving the Problem A vibration isolating rubber is attached to the outer periphery of the upper end of the lower lever, and the cylindrical lower part of the anno/shishi/e is fitted on the outside of this vibration isolating rubber, so that the upper lever can move from the lower lever to <- The upper lever is molded from a soft material.

When the operating upper lever 1'J is operated, the force acting on the ankle is absorbed not only by the vibration isolating rubber but also by the bending deformation of a, /f and 1<-, thereby reducing the burden on the vibration isolating rubber.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals given to the same parts as in the conventional structure.

In the first embodiment shown in FIG. 1, 1 indicates a lower lever, <-, and a vibration isolating rubber 2 is fitted and fixed to the outer circumference of the upper end of the lower lever 1.

And, on the outside of the vibration isolating rubber 2, there are holes and holes, 5j-3.
The upper lever 3 is attached to the lower lever 1 by fitting the cylindrical lower part of the upper lever 3 into the lower lever 1.

The upper lever 3 is molded from resin as a flexible member, and a shift knob portion 7 having a weight 6 installed therein is integrally molded at its upper end.

Here, the weight 6 is used to change the mass of the vibration system consisting of the lower lever 1, the upper lever 3, and the vibration isolating rubber 2. As shown in FIG. 1, the vibration isolating rubber 2 is designed to reduce its rigidity in order to improve the shift feeling in the P direction.
Natural frequency of direction f. It also deforms.

Therefore, the size of the weight 6 is changed and set to an optimal value.

According to the above embodiment structure, when the occupant grasps the shift knob portion 7 of the upper lever 3 and operates the upper lever 3,
The impact caused by this operating force is absorbed by the vibration isolating rubber 2 and also by the bending deformation of the upper lever 3, which itself is molded from resin.

Therefore, in order to improve the shift feeling,
A part of the load originally applied to the vibration isolating rubber 2, which has low directional rigidity, is shared by the upper lever 3, and the durability of the vibration isolating rubber 2 can be improved.

Since the shift knob portion 7 is molded into the upper lever 3, there is no possibility of the shift knob becoming loose or coming off unlike conventional shift knobs.

Next, FIG. 2 shows a second embodiment.

This embodiment is similar to the previous embodiment in that the upper lever 3 is molded of resin and the shift knob part 7 is integrally molded, but the weight 6 is not placed inside the shift knob part 7, but rather in the shift knob part 7! <It is installed near the lower end of lever 3.

According to this embodiment, it is possible to reduce the load applied to the vibration isolating rubber 2 when operating the collar lever 3, and there is an advantage that vibration acting in the direction of the arrow is less likely to occur.

Next, a third embodiment will be explained with reference to FIG.

This embodiment is similar to the first embodiment in that the upper lever 3 is molded from resin, a shift knob part 7 is integrally molded on the upper end of the upper lever 3, and a weight 6 is installed inside the shift knob part 7. However, a weakly rigid portion 8 having a small diameter is provided between the shift knob portion 7 and the upper lever 3. This weakly rigid portion 8 is advantageous in that the vibration of the base side of the upper lever 3 does not reach the soft knob portion 7 due to the bending vibration of the weakly rigid portion 8, and the vibration of the shift knob portion 7 is suppressed.

Furthermore, since the rigidity in the P and direction can be reduced, a good shift feeling can be obtained.

Incidentally, as shown in FIG. 4, the area around the shift knob portion 7 may be covered with a soft resin material 9.

Next, a fourth embodiment will be explained with reference to FIG.

In this embodiment as well, the upper lever 3 is molded from resin, but a metal bolt IO is implanted in the upper end of the upper lever 3, and a shift knob 5 similar to the conventional one is attached thereto. In this embodiment as well, the burden on the vibration isolating rubber 2 when operating the upper lever 3 is reduced.
is reduced by bending and deforming, and the durability of the vibration isolating rubber 2 can be improved.

Further, since the shift knob 5 has the same structure as the conventional one, this upper lever 3 is advantageous in that it can be easily replaced with a conventional upper lever.

Through experiments, conventional control lever and weight 6
When examining the relationship between the transfer function dB and the frequency Hz with a mount roll lever that integrates the Ta.

Note that the present invention is not limited to the above embodiment (the control lever is not limited to a gear shift lever).

As described in detail, the present invention has the effect of improving the durability of the anti-vibration comb while maintaining optimal shift feeling.
