Description

The utility model “Device for transmitting electrical signals and returning the turn signal lever” (hereinafter referred to as the device) relates to the field of vehicle production and is included as part of the steering installation. Designed to transmit electrical signals to electrical components of the vehicle, for example, an audio signal switch located on the steering wheel, as well as to return the direction indicator lever to its original ("zero") position, after the vehicle completes turning right or left.

The existing analog device (for example, a device for transmitting electrical signals and returning the direction indicator lever, which is part of the steering system of cars of the VAZ 2110 family) is a structure consisting of (Figure 1) from:

I) parts mounted on the steering wheel 14, namely:

the holder of the contact rings 1, the pusher 3, the spring of the pusher 4, the contact inner ring 8, the contact outer ring 10, the screws 12, the washers 13.

II) parts mounted on the steering column (the column is not shown in the diagram), namely: connector 2, bolt 5, washer 6, nut 7, contact inner plate 9, external contact plate 11. Attach to the right and left grooves of connector 2 ( but they are not included in the device itself) the so-called “steering column switches”, performing, for example, the following functions: switching on - turning off the main beam, switching on - turning off the electric motor of the windshield washer. In particular, in the right groove of the connector 2, the direction indicator mechanism is also attached, the lever of which is in the “working” state by the movement of the driver’s hand, and the lever returns to its original (“zero”) position after touching the pusher 3.

The disadvantages of this design include the fact that the positioning accuracy of the elements of the electrical signal transmission device relative to each other has a large error, since they are attached to different elements of the steering installation. So the holder of the slip rings 1, and accordingly the slip rings, are mounted on the steering wheel 14, which in turn is mounted on the steering shaft (the shaft is not shown in the diagram). Connector 2, and therefore the contact plates, are mounted on the steering column.

The consequences of inaccurate positioning are, on the one hand, the lack of contact between the contact rings and the contact plates and, as a result, the inability to transmit electrical signals to circuit elements located on the steering wheel, on the other

side (with a minimum clearance between the slip ring holder and the connector) increased wear of the slip rings and contact plates. In addition, inaccurate positioning is the cause of the deformation of the pusher 3 and, as a consequence, the inability to automatically return the direction indicator lever.

The purpose of the proposed utility model is to create a device design, the accuracy of positioning of the individual parts of which, relative to each other, does not depend on external factors.

Presented in FIG. 2, the construction (example) of the proposed utility model of the device consists of an electric signal transmission device 15, the housing 19 (fixed part) of which (FIG. 3) is attached to the connector 2 with screws 16. In this case, the shaft-cover 18 (movable part) of a device for transmitting electrical signals, connected, for example, by means of a spline connection to a pusher 17. The device is mounted on the steering column of the vehicle using a bolt 5, washer 6, nut 7.

Advantages of the proposed utility device model:

- parameters characterizing the quality of transmission of electrical signals and the ability to control the return lever of direction indicators do not depend on external factors;

- the error in the positioning of the device on the steering column is automatically compensated by the fact that the protrusion (s) on the moving part of the device for transmitting electrical signals are able to move freely (in the direction of the axis of the steering shaft) in the holes located on the steering wheel (Figure 2).

As an explanation of the proposed utility model, it should be noted that:

- the basis of the design of the device for transmitting electrical signals can be laid any method known in science and technology for transmitting electrical signals from a stationary product to another product rotating around it, for example, as shown in FIG. 3, using contact elastic plates 9 and 11 mounted on a fixed parts (base 19) and slip rings 8 and 10 fixed on the movable part (cover-sleeve 18), taking into account that the number of revolutions of the steering wheel (and, therefore, the movable part of the device) from the "center flaxen "position to the right or to the left, is limited;

- the movable part of the device for transmitting electrical signals can be connected to the fixed part of the device for transmitting electrical signals by any method known in science and technology, providing the possibility of their mutual rotation relative to each other, for example, as shown in Figure 3, using the ring 20;

- the connection of the "movable" and "fixed" contacts of the device with the electric circuit of the car can be carried out by any method known in science and technology, for example, by means of a plug-in connection;

- the terms "fixed part", "fixed contacts", indicate products that are part of the device, and which when the steering wheel is turned do not change their position relative to the steering column;

- the terms "moving part", "moving contacts", denote products that are part of the device, and which, when the steering wheel is turned, have the ability to change their location and / or arrangement of their elements relative to the steering column and / or its elements;

- the connection of the electrical signal transmission device to the connector can be carried out by any method known in science and technology, for example, as shown in FIG. 2, using screws 16;

- the device can be mounted on the steering column by any method known in science and technology, for example, as shown in FIG. 2, using hardware products 5, 6, 7;

- the term "pusher", in this context, means a product of any design (for example, in the form of a pin pos.3 of Fig.1, or in the form of a sleeve pos.17 of Fig.2) in contact with the return lever of the direction indicator, only if certain the positions of the movable part (i.e., at certain positions of the steering wheel), while the pusher can be an element of the movable part of the electrical signal transmission device and can be structurally made, for example, in the form of protrusions;

- the number and design of the protrusions of the movable part of the electrical signal transmission device for transmitting movement from the steering wheel to the elements of the device (Figure 2) is limited only by the condition of expediency.
