JPS6022532A - Shift stage indicating device for vehicle - Google Patents

Abstract

PURPOSE:To make it possible to efficiently and economically drive a motor-cycle even by a beginner, by indicating running speed ranges in accordance with the shift stages of the a motor-cycle. CONSTITUTION:In a motor-cycle, when a shifter shaft 2 is rotated in association with the rotation of a change pedal shaft, cam surfaces 3l, 3s, 3t, 3n corresponding to shift stages and formed in a cam secured to the shifter shaft 2, actuates a contact 5 which therefore closes any one of stationary contacts 6l, 6s, 6t, 6n in accordance with the associated shift stage. Therefore, one of indicating lamps Ll, Le, Ls, Lt, Ln is turned on to be indicated in the indicating window of a travelling meter 7. With this arrangement an appropriate running speed range corresponding to the associated shift stage is indicated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gear position display device for a vehicle such as a motorcycle or an automobile, and particularly for a multi-speed vehicle.

In order to drive this type of multi-speed vehicle efficiently and economically, it is necessary to select the gear position according to the traveling speed of the vehicle.

However, the above-mentioned selection of the gear stage and judgment of the switching time wl, etc. depend on the driver's experience and familiarity, and therefore are not necessarily easy, especially for those with little driving experience.

The present invention has been proposed in view of the above-mentioned points, and it is possible to select an appropriate gear position and when to change it by displaying the current gear position and the travel speed range suitable for that gear position when driving a vehicle. The purpose is to make it easy for drivers to detect.

That is, in a multi-speed vehicle, a lighting circuit is provided to indicate the selected gear position in conjunction with the gear shift mechanism, and the lighting circuit indicates the travel speed range suitable for the selected gear position at that time. It is characterized by having been configured.

An example in which the present invention is applied to a rotary three-speed motorcycle shown in the drawings will be specifically described. A cam 3 is provided on a thick shaft 2 that rotates in conjunction with the switching operation of a change pedal 1 shown in FIG. 1, and a cam surface of a low 3, a second 3S, a top 3, and a neutral 3n are formed on the circumferential surface of the cam 3. An eight-shaped movable contact 5 is brought into contact with the circumferential surface of the cam 3 by a spring 4.

- Install Wn on the glass G or dial plate of the speedometer 7. The arc lengths of the respective display windows W, Ws, and Wt are switched to provide a travel speed range suitable for the selected gear position. Note that the above-mentioned display window W pattern/W s a W t may be represented by different colors on the glass surface. A shield for illumination light is installed between adjacent display windows to prevent incorrect display.

When the transmission is in neutral N in the configuration shown in "-", the movable contact 5 comes into contact with the cam surface 3n of the cam 3 shown in FIG. The light is turned on to illuminate the display window Wn in FIG.

From this state, when the change pedal l shown in Fig. 1 is operated to shift the transmission to low L, the thick shaft 2 shown in Fig. 2 rotates in conjunction with this, and the movable contact 5 that was in contact with the cam surface 3n moves to the position shown in Fig. 2. As shown in the figure, the contact 5a contacts the cam surface 3 and switches from the fixed contact 6n to the fixed contact 6n. Then, the lamp Ll lights up, the display window Wl in FIG. 3 is illuminated, and the range of running speed suitable for the low L gear stage is displayed using the scale of the speedometer 7, the phase shift 8, etc. Furthermore, when switching the transmission from Low L to 2nd S/Top T, the display window W will appear in the same manner as above.
S@Wt is illuminated to display the traveling speed suitable for each gear stage S and T.

Since the present invention has the above-mentioned configuration, even a person with little driving experience can easily select the appropriate gear position because the gear position selected by the change pedal 1 or the like and the travel speed range suitable for the gear position can be seen at a glance.

For example, when changing the gear position from low L to second S, or from second S to top T, the change can be made at the point where the display W/Ws and Ws/Wt for each level overlap, making it easy to determine when to change. be able to.

Furthermore, as long as the engine is operated within the indicated range, the engine speed will not exceed a certain limit, thereby preventing a reduction in engine life due to overspeeding of the engine. In this case, it is possible to draw the attention of the occupants by displaying a red message such as W, W s', Wt, etc. in a portion exceeding the above-mentioned display range, or by issuing a warning.
