Description

The invention relates to the diagnosis of motor vehicles and military wheeled vehicles, in particular to means for measuring the total backlash in the steering. In addition, it can be used in instrumentation, as well as in mechanical engineering for the release of vehicles from production.

A device for diagnosing steering control of a vehicle, which contains discrete sensors for starting the steered wheels, a pulse shaper, OR circuits and converters / 1 /.

The disadvantages of this device: it has a complex and expensive design, is not acceptable for widespread use in operating conditions.

The closest technical solution, selected as a prototype, is the device KI-28163 GOSNITI for diagnosing steering. It includes an indicator of the start of rotation of the steered wheels, which contains a limit switch with a signal lamp that interacts with the steered wheel, and a rack with levers for setting the limit switch to a predetermined position relative to the steering wheel tire / 2 /.

The disadvantages of the known device: the limit switch has an unreliable design, a rack with levers in the aggregate forms a massive and large-sized device. Installing a switch using a rack with levers is a laborious process. Moreover, due to the design features of vehicles, the use of this detector is not always possible.

The objective of the invention is to improve the operational properties of the device for diagnosing steering based on the use of modern, reliable and affordable computer elements - a mouse with a rug.

The invention consists in the following. The limit switch is made in the form of an optical computer mouse with a light signaling device interacting with a steered wheel and with a computer mat placed on a stand. A rack with levers - in the form of an elastic tape. The mouse with the indicated tape is connected to the tire of the steered wheel and is connected to a power source, which can be made in the form of an adapter connected to an alternating current network, or in the form of a block of accumulators or batteries. In this case, the power source in terms of the output parameters of the electric current coincides with the input parameters of the mouse power supply. To ensure the possibility of observing the beginning of the rotation of the steered wheels, a signal lamp is connected in parallel to the light signaling device of the mouse, located in the visibility zone of the diagnostic operator or on the instrument panel.

Together, this allows us to create, on the basis of common computer elements (mice with a rug), a device for diagnosing steering with a reliable, easy-to-use and universal indicator of the start of turning steering wheels.

Figures 1 and 2 show a device for diagnosing steering with a computer mouse - an indicator of the start of turning of the steered wheels. At the same time, an integral part of the device is shown — an indicator of the start of turning of the steered wheels, made on the basis of an optical computer mouse. To do this, the mouse 5 through the cord 7 is connected to a power source, for example, with an adapter (not shown) connected to an AC network, or with a battery or battery pack (not shown). In this case, the power source in terms of the output parameters of the electric current coincides with the input parameters of the power of the computer mouse 5. A signal lamp (not shown) is connected to the light signaling device of the mouse 5 in parallel with the cord 3, located in the visibility zone of the diagnostic operator or on the instrument panel for diagnosing the steering management.

The principle of operation of the device is as follows. On the base 1, near the steered wheel 2 (at a distance of 2-3 cm from the side surface of its tire), a stand 8 with a computer mat 6 is installed. A mouse 5 is placed on the mat 6 so that its free end contacts the surface of the tire. In this position, the mouse 5 is fixed with the wheel 2 by means of an elastic adhesive tape of the “skoch” type, one end of which is glued to the upper surface of the mouse 5 and the other to the surface of the tire 2. If necessary (if there are no 5 built-in power supply elements in the mouse) connect mouse 5 to a power source. The steering wheel start warning light is ready for use. The steering wheel is turned, for example, to the left — there comes a moment when the steered wheel 2 rotates to the left, at which its tire acts on the mouse 5. In this case, the mouse 5 interacts with the mat 6 — the light signaling device of the mouse 5 turns on and the signal lamp lights up at the same time. Zero the instrument. The light signaling device of the mouse 5 turns off automatically - the signal lamp goes out. Turn the steering wheel to the right - accordingly, the moment of rotation of the steered wheel 2 to the right comes, at which the mouse 5 moves in the same direction by means of the tape 4. As a result, the light signaling device of the mouse 5 turns on and at the same time the signal lamp lights up. The device measures the received backlash value in degrees.

A device for diagnosing steering with a computer mouse is proposed - an indicator of the start of turning steering wheels. It includes modern and affordable computer elements: an optical mouse 5 with a light signaling device and a mat 6. For this, mouse 5 is connected via a cord 7 to a power source, for example, with an adapter (not shown) connected to an AC mains or with a battery pack or batteries (not shown). In this case, the power source in terms of the output parameters of the electric current coincides with the input parameters of the power of the computer mouse 5. A signal lamp (not shown) is connected to the light signaling device of the mouse 5 in parallel with the cord 3, located in the visibility range of the diagnostic operator or on the instrument panel for diagnosing the steering management. The mouse 5 by means of an adhesive tape 4 is attached to the side surface of the tire of the steered wheel 2 and placed on a stand 8 with a rug 6. Together, this made it possible to create, based on common computer elements (a mouse with a rug), a device for diagnosing steering with reliable, convenient to use and universal signaling device for the start of steering wheel steering. The proposed device provides the ability to check the steering of vehicles in accordance with modern requirements of GOST 51709-2001.
