Embodiment Construction

[0022] in figure 1 with figure 2 The indicating device 1 according to the present invention is shown in respectively, and the indicating dial is omitted. The main components shown are the ring indicator 2, the drive unit 3 and the support 4. The ring indicator is provided with teeth 6 extending in the circumferential direction 5 on the outer diameter. The tooth part 6 is connected with the driven gear 7 of the drive unit 3 having a stepping motor, and the stepping motor is responsible for moving the ring indicator 2 in the circumferential direction 5 or opposite to the circumferential direction 5. The ring indicator 2 is supported on the support 4 with three-piece radial bearings 9, 9a. The three-piece radial bearings respectively have pulleys. The pulleys have a U-shaped end surface tooth profile facing the basic part, ring-shaped The meshing outer circumference of the indicator 2 is guided in the profile of the end face. The radial bearing 9a denoted by 9a is designed to ...

Abstract

The invention relates to an indication device (1) having: an annular indicator (2), which is movably supported in the circumferential direction (5); and a drive unit (3), which is movably supported in the circumferential direction (5). (5) The annular indicator (2) is driven, wherein the annular indicator (2) interacts with the stop (10) in a limited manner with respect to the circumferential movement of the annular indicator. Especially during synchronization, radial decoupling often occurs in conventional annular indicators, which is avoided by the invention. In order to solve this problem it is recommended to arrange the stopper (10) directly near the drive unit (3). A decisive advantage is that the tangential force on the annular indicator (2) from the drive unit produces a very small disengagement moment on the annular indicator (2).

Description

Technical field [0001] The present invention relates to an indicating device. The indicating device has: a ring-shaped indicator which has the shape of a ring or the shape of a ring-shaped part and is movably arranged in the circumferential direction; a driving unit which drives the ring-shaped indicator in the circumferential direction The ring-shaped indicator has a restrictive area, and the indicating device has a stopper, and the stopper and the restrictive area together play a role of restricted circumferential movement of the ring-shaped indicator. Background technique [0002] In the era of increasing information density in the cab of a motor vehicle, a huge challenge is especially presented to manufacturers of combined devices, that is, to present high-density information with partial safety-related meanings in a good and visible manner. Attention should also be paid to relevant safety regulations, which should ensure a certain accuracy of speed display under conditions o...
