Description

In the copyright certificate Mg. ZZZb describes a device for recording a track traveled by a car or motorcycle, characterized in that a writing device located opposite a paper tape, rewinding from one reel to another with a driving roller, rotated by a transmission from the front wheel of a car or motorcycle, is mounted on a spring mounted on a vertical axis, rotating with an appropriate gear from a pivoting mechanism or a steering wheel of a car or motorcycle.

In the proposed device, a second writing device is used, placed along the axis of the roll and intended to draw an axial line on the tape.

In the schematic drawing of FIG. 1 depicts a top view of the cart with the device; FIG. 2 shows a tape with a record on it and FIG. 3-image of the path, made up of entries on the tape.

Under the carriage body / there is a tape 2, which is taken from the drum 3 onto the drum 4, which is driven in rotation through the appropriate gears from the rear axle 5 of the vehicle. On the front pivot axis b fortified

chag 7, to which, besides the writing device 9 at its end, is attached a second writing device 5 located at the point of rotation of the front axle of the wagon.

When the carriage is moving along the straight two writing devices 8 and 9, arranged one after the other, one straight line is drawn on the tape. When turning the front axle 6 at some angle tf. device 8 continues to write straight along the axis of the tape 2, and writing device 9, which is biased towards device 8, writes on the tape a second parallel to the first line and continues to write it until the front axle 6 of the wagon returns to its original position, and then both writing devices will again write one line on the tape. The tape with the recorded path will have the form shown in FIG. 2

After the trip, the tape is removed and the actual path taken by the vehicle for the trip is determined by the recording. For this, in each segment //, IV, V, V7, etc. (Fig. 2), the tapes with the same deviation and side line drawn by the device P from the center line drawn by the device 8 measure the value of this deviation o length / of each segment. Then the angle of rotation of the front axle over this length is determined by the formula -–, where c is a constant value, equal to the distance between the writing devices 8 vi 9. The radius r along which the wagon moved during the drawing of this segment

is equal to r, where b is a constant tf

The mask is equal to the distance between the front and rear axles of the wagon. Angle © (in radians), which during this time

The cart is wound, equal to -. Know

The values of r and in for each curvilinear section of the track and the magnitude / for the straight linear sections can be drawn all the way traveled by the vehicle (Fig. 3).

The subject matter of the invention.

An embodiment of the device for recording the track traveled by a car or motorcycle according to the author's certificate No. ZZZb, characterized using a second writing device 8 placed along the axis of the steering wheel and designed to draw an axial line on the tape. to the dependent author's certificate of V.
