JP2010100272A - Direction display apparatus of automobile front wheel - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To compactly inexpensively provide a device for visually displaying the direction of an automobile front wheel to a driver. <P>SOLUTION: When a rotation ratio between a gear 3 and a gear 5 is equal to an oscillation angle ratio between an automobile steering wheel and a front wheel, the gear 5 that is ring-shaped is synchronized with the movement of the front wheel. The ring-shaped gear 5 that is magnetized is fitted in an outer circumference of a pipe so that the rotation angle of the gear 5 is transmitted to an indicator provided at the center of the steering wheel. A magnetic line from the gear 5 penetrates the nonmagnetic pipe, and therefore a bar magnet 6 in the pipe is magnetically coupled and integrated with the gear 5. Then, an indicator needle 7 of the indicator provided at the center of the steering wheel is appropriately provided on the shaft of the bar magnet 6, so that the indicator needle consistently indicates a direction of the front wheel irrespective of the rotation of the steering wheel. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention relates to safe driving of automobiles.

There is a telemeter ring. However, there is no application for this purpose.

Problems to be solved by the invention

The front wheel direction may not be recognized correctly after a large handle is turned in a car garage. The present invention informs the driver of this.

Means for solving the problem

(Structure) The donut-shaped (hereinafter referred to as a gear box) indicated by 2A in FIG. 1 is a ring-like shape in which a part of the handle shaft 14 is a non-magnetic pipe 1 (hereinafter simply referred to as a pipe) and is fixed to the pipe. The number of rotations of the gear 3 is dropped by the six small gear groups 4, and a series of mechanisms for transmitting torque to the ring-shaped gear 5 that can rotate around the outer periphery of the pipe is housed, and the main body itself Is inserted into the pipe 1 to support it. Accordingly, when the pipe rotates around the pipe, the phase (phase) between the front wheel and the pointer of the instrument is shifted, so that the panel 8 and the elastic plate 9 are restrained.
(Operation) If the rotation ratio between the gear 3 and the gear 5 is made equal to the swing angle ratio of the steering wheel to the front wheel unique to the automobile, the ring-shaped gear 5 is synchronized with the movement of the front wheel. In order to transmit the rotation angle of the gear 5 to an instrument provided at the center of the handle, a magnetized ring-shaped gear 5 as shown in FIG. 2 is fitted on the outer periphery of the pipe as shown in FIG. Then, the magnetic lines of force from the gear 5 pass through the non-magnetic pipe, so that the bar magnet 6 in the pipe is integrated with the gear 5 by magnetic coupling (magnetic and coupling). Therefore, if the pointer 7 of the instrument provided at the center of the handle is properly attached to the shaft of the bar magnet 6, the pointer can always indicate the direction of the front wheel regardless of the rotation of the handle.

The invention's effect

In the case of this purpose, it can be realized smartly by using voice and IT, but in the case of this case where necessity is not high, it is avoided in terms of space problems and new failure sources. It will be. Therefore, the present invention is the starting point of the idea, the purpose is to install a meter in the center space of the steering wheel that is the only remaining feeling when viewed from the driver's seat, and to display the angle of the front wheel with the pointer, the minimum space, the minimum cost, the minimum It is something that will be realized through maintenance.
In addition, since the pointer is in the center of the handle, there has been a merit that the line of sight can be recognized without being bent.

Best mode of implementation

The small gear group 4 in the gear box 2A in FIG. 1 is arranged so as to surround the pipe 1, and since the upper part is empty, it is oval as shown in FIG. 3, and a weight is added to make the lower part heavy. The connecting plate 9 with the panel is not necessary and can be miniaturized. Further, since the gear in the gear box is small, it is necessary to incorporate and support an elastic body so as to absorb a gap generated by vibration or aging.
