BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving recorder known as a tachograph, and more particularly to a driving recorder which automatically operates immediately when the vehicle is driven.

The mileage recorder is used to record data on the use mode of the vehicle, such as the driving route, the driving speed, and the use time. This data relates to the record of vehicle usage by one or two drivers and the recording trajectory on a single chart disk (or two chart disks when using two drivers) driven in real time by a unit such as a timepiece. It is recorded by a recording device that provides a trace or a recording line.

The tachograph includes a recording device for obtaining a recording trajectory line on a chart disk. Therefore, a recording apparatus is used that works both during loading and unloading at the vehicle stop, during repair work such as vehicle repair, waiting, and while driving the vehicle. The driver tachograph is typically driven by an electric vibrator to provide thick lines on the chart, which are typically mounted on a mounting plate that can be located on an axis located inside the tacho housing or inside the tachograph.

Thus, a special motor is usually provided to control the recording device to thicken the locus line recorded on the chart disk when the vehicle is stopped, which ultimately reciprocates the stylus under mechanical drive control driven by the speedometer of the vehicle. This is because the conventional method of obtaining a thick locus line by moving is obviously inadequate. Even if the shortcomings of using these special motors are not taken into account in detail, the driving state in these devices is on the chart disk with a trajectory line corresponding to the "drive time" recorded in bold by moving the stylus back and forth according to the mechanical drive of the speedometer. It is important to know that it is displayed. However, this is not done automatically, but the operator must operate the knob on the front of the housing. Such manipulation is required by law. If the driver forgets, he will violate the law and eventually misread the chart disk. The operator must perform the above operation frequently. This operation is very inconvenient, and the chart disc reader must always closely monitor whether the driver performs the operation faithfully.

Other known devices use the position of a mechanical member of the speedometer to measure the drive time, which member is returned by a "mechanism" used to drive the chart disk in real time, or controlled by an electronic circuit. It is fed back by a particular feedback device, such as an electromagnetic type device or a bimetal strip.

At first glance, it seems very desirable, but these various devices are complex and expensive in structure, requiring the use of expensive devices that many manufacturers are reluctant to try to actually record their travel time automatically.

The preferred embodiment of the present invention provides a tachograph which is operated automatically as soon as the vehicle is driven, but whose structure is simple and reliable.

Preferred embodiments of the present invention also provide a good readability of driver working hours.

The preferred embodiment of the present invention provides a tachograph that can be easily used for two-person driving.

Finally, a good tachograph according to the invention is made to have an "intrinsic safety" which is suitable for the overland transport regulations of dangerous substances.

The present invention provides a driving recorder that can be automatically activated immediately when driving a vehicle. The driving recorder includes a recording device for obtaining a recording trace on a chart disc, and a recording device for obtaining a trace line for distinguishing a vehicle usage mode. An additional guide device which includes an interactive multi-position guide cam, in which case the tachograph can replace the multi-position guide cam regardless of one of the positions at which the guide cam is located. And an operating device controlled by the vehicle tachometer drive, which automatically performs the replacement immediately upon driving of the vehicle so that the recording device records the locus line corresponding to the driving position.

The additional guiding device is advantageously constituted by the additional cam having an internal diameter coaxial with the multi-position guide cam and suitable for positioning over the multi-position guide cam so as to automatically replace the multi-position guide cam in the driving position.

Preferably, this additional cam is recorded in the drive position to obtain a support ring capable of sliding over the axis of the multi-position cam and a cross-section of the crescent shape and a thicker trajectory than that obtained with the multi-position cam. Consists of side bars that automatically interact with the device, the multi-position cams and additional cams are effectively arranged to rotate at the same time so that they are affected by the springs that are intended to separate them from each other.

The actuating device for automatically replacing the cams in the drive position is essentially a drum that is rotated by the drive of the vehicle speedometer, and one end thereof interacts with the drum such that the replacement occurs immediately when the speed of the vehicle exceeds a set threshold. It is effective to consist of a lever that acts and whose other end interacts with an additional guiding device. For example, the drum may have a circular track on which the associated end of the lever is pressed, which track is supported by a notch having an inclined slope that can interact with the end when the vehicle speed passes a threshold speed set at zero. It is becoming. The drum additionally drives the output indicator shaft of the tachometer.

This tachograph is, for example, a very low threshold speed (e.g., 0.1 km / Each time h) is reached, it effectively includes a device that enables automatic replacement of the drive position.

In a variant, the two driving apparatuses can be distinguished from each other by providing two guide devices, two operating devices and two recording devices for recording on two chart discs. The actuator can be controlled to automatically replace any cam in the drive chain. By providing a control drum as described above, the drum is preferably common to both drive paths and interacts with two levers, two guide devices, and two recording devices.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The illustrated driving recorder includes a recording device 1 for providing a recording locus line on a chart disk 2 driven in real time by a timepiece 3, and a recording device for providing a locus line for distinguishing a vehicle use mode ( A control device 4 which acts directly on 1).

The control device 4 of the present embodiment is directly connected to the timepiece drive motor, and is provided with a multi-position guide cam 5 which works together with the recording device 1 to provide a trajectory line having a different thickness at each of the positions. . The direct connection state is provided in which the gear 6 mounted on the output shaft 7 extending from the timepiece drive motor is engaged with the gear 8 which is the starting point of the drive path of the control device 4, the drive path being By means of the gears 9 and 10, the multi-position cam 5 successively drives the slidable shaft 11, and the assembly is fixed by fixing members 12 and 13 fixed to the housing of the device. The stylus support 15 has a cam-following wheel 14 that pushes the multi-position cam 5, which in particular presses the tracks 16, 16 ′, 16 '' of the cam (in the case of the drawing). 16 ''), wherein the selection of the track is controlled by a manual control knob (not shown) installed on the front of the housing and acting on the member 17 which moves the cam up and down along its axis.

By selecting an appropriate track, the type and thickness of the locus line can be selected, the shape of the locus line being dependent on the number and type of tracks available. In this case, the track 16 is circular and corresponds to the rest position where a single fine circular line is recorded on the chart disc 2. The non-circular tracks 16 ′ and 16 ″ correspond to two working positions with the vehicle stationary, namely loading and unloading and repair of the vehicle, respectively.

The following description relates to an element capable of automatically providing a record of the drive position without the need for manual operation.

According to the basic aspect of the present invention, the recording apparatus can correspond to the driving position by the additional guide apparatus 18 and the recording apparatus 1 which can replace the multi-position cam 5 irrespective of any position occupied by the cam. It also includes an actuating device 19 driven and controlled by the speedometer of the vehicle such that the additional guidance device 18 automatically replaces the multi-position cam immediately upon driving the vehicle so as to produce a locus line.

The additional guide device 18 can be implemented in a number of ways with the important feature that the guide device replaces the cam 5 when the vehicle is driven. The illustrated embodiment includes a cam shaped guide device 18 coaxial with the multi-position cam 5. This guiding device 18 has a side bar 21 which has a slidable support device 20 on the shaft 11 and a meniscus cross section, which side bar is moved over the cam 5. The support surface of the cam-following wheel 14.

In order to ensure good motion transfer, it is effective to rotate the cam 5 and the guide device 18 simultaneously. The action is shown by the end 22 of the cam 5 entering into the side groove 23 in the guide device 18. The shaft 11 is rotated by the movement of the timepiece 3, and the cam 5 and the guide device 18, which are acting on the spring 26, can be rotated together irrespective of their relative positions in the axial direction. And a pin 24 engaged in the longitudinal groove 25 through the support ring.

In the illustrated embodiment, the tracks 16 ′ and 16 ″ are designed so that the crescent inner surface of the side bar 21 is almost circular and has an inner curvature with the same radius as the circular track, while the outer surface is selected. The shape and the maximum radius are selected according to the recording method and the thickness of the selected locus line.

The actuator 19 is coupled to the vehicle speedometer driver. A block 27 is connected to a conventional speedometer drive consisting of an output gear 28, which is in a known manner a tachometer pointer 29 and a speed recorder 30 ( These are schematically shown). The drum 31 is driven by the tooth 28 through the auxiliary tooth 32 and has a circular track which is hampered by the notch with the inclined portion 33. The lever 34 (rotatedly supported as shown) has one end interacting with the notch having the inclined portion 33 and the other end interacting with the washer 35 supported against the guide device 18. Has

Therefore, as soon as the vehicle speed exceeds the set threshold, that is, the drum 31 is at an angle sufficient to raise the corresponding end of the lever 34 from the notch 33 (this position is shown by the dashed-dotted line in the figure). As soon as it is rotated, the other end of the lever urges the guiding device 18 downward over the force of the spring 26 to the cam 5. Since the cam 5 and the guide device 18 are mutually coupled, to prevent contact with the cam-following wheel 14 which prevents the guide device 18 from moving over the cam 5 in the driving position. The side bar 21 will always be in the proper radial position. This state is achieved regardless of the particular track on the cam 5 that the cam-following wheel 14 follows when the device is replaced by the drive position.

Hereinafter, the technical configuration and operation of the present invention will be described in more detail with reference to the drawings.

When the vehicle is driven, the drum 27 and the gear 28 of the vehicle speedometer driver rotate by the output of the engine, and the rotational motion of the gear coupling is transmitted to the drum 31 through the gear 32. The drum 31 is provided with an inclined portion 33 at which one end of the lever 34 is axially fixed at a predetermined position, and one end of the lever 34 located in the inclined portion 33 is provided with a drum 31. This rotation raises to the position of the dashed-dotted line shown in the drawing, so that the other end presses down the washer 35 of the guide device 18 so that the guide device 18 is pushed downward and the end 22 of the cam 5 is pressed. ) Enters into the side groove 23 of the guide device 18 so that the multi-position guide cam 5 and the guide device 18 are rotated at the same time. At this time, the cam-following wheel 14 connected with the recording device 1 is in contact with one of the tracks 16, 16 ', 16' 'of the multi-position guide cam 5 corresponding to the stop of the vehicle. Is pressed on the side bar 21 of the guide device 18 via the track 16 '' by pressing the other end of the lever 34 downwardly. Since the maximum diameter is larger than the maximum diameter of the track 16 '', a track line thicker than the track 16 '' can be recorded on the chart disk 2.

It is also effective to have a device that can automatically and quickly replace the cam with the drive position as soon as the vehicle speed exceeds a very low speed threshold (eg as soon as reaching 0.1 km / h). For example, a control system (not shown) may be provided to move the vehicle speedometer output at a small angle immediately after exceeding a low threshold speed. Thus, a rapid replacement artificially obtained by an electrical device, preferably a mechanical device, can avoid any defects related to transitional situations.

For example, the control action of performing cam replacement at the drive position can be configured as follows.

When the vehicle is stopped: The speedometer indicator is located at the terminal stop position of the indicator which is misdirected at a speed of 8 km / h.

When driving slowly: As soon as the actual speed of the vehicle reaches 0.1 km / h, the above-mentioned devices and control systems move the indicator rapidly in the forward direction to indicate 11km / h of a misdirected speed (the corresponding trajectory line is driven). The abrupt movement forward to bring it into position causes the cam replacement action described above.

When driving at a constant speed of the vehicle: As soon as the actual speed of the vehicle exceeds 11 km / h, the speedometer indicator normally shows the speed beyond the misdirected thresholds 8 km / h and 11 km / h.

A tachometer type tachograph comprising a housing (not shown) incorporating a recording device 1, a control device 4, a cam 5, and an operating device 19, (not shown) The cover supports the timepiece 3 and the chart disc 2. Thus, the direct connection between the timepiece operation and the recording device 1 controlling the cam 5 is such that the tooth 6 is removed from the cover. This is achieved by closing the rotatable lid as it protrudes into the rest of the housing, which is a trajectory on the chart disk when the vehicle is stopped to correspond to a certain thickness of the trajectory line selected by the cam 5, i. This means that the line can be written in bold.

In other words, when the vehicle is driven, the guide device 18 moves over the cam 5 to automatically replace the cam 5, thereby obtaining a trajectory line having a thickness different from ever before, thus reading the chart disk very easily. can do.

If two driver devices are required, a second drive path using a similar device can be readily provided. In this case, the second drive path uses its own direct connection actuator from the timepiece drive mechanism to drive its own cam and recording device (i.e., receives movement from the gear wheel 9), and its drive lever. Should be equipped with its own actuating device on the vehicle speedometer drive using a single control drum used in common with other drive paths.

The cam 5 can have three tracks for recording various kinds of recordings on the chart disk, so that all four kinds of driver working states can be recorded.
