Abstract
Description
One embodiment of the present invention relates to a shaft and yoke assembly, and more particularly, in the case of being used in a steering device, a misassembly is required when connecting a shaft of a steering column or a gearbox and a yoke of an intermediate shaft made of a universal joint. In addition, the present invention relates to a shaft and yoke assembly which can be prevented, and to prevent stress concentration in the bolting groove after complete assembly.
Various devices are installed in the car to improve the safety of the car and the driver's convenience. Among them, the steering device is a device that allows the driver to turn the steering wheel freely to change the driving direction of the car. It is a device that assists the vehicle by moving the center of rotation in the desired direction.

Accordingly, the present invention has been made to solve the above-described problems, the shaft and yoke assembly to prevent the misassembly when connecting the shaft and yoke, and to prevent the concentration of stress in the bolt coupling groove after complete assembly The purpose is to provide.
In order to achieve the above object, the shaft and yoke assembly according to the embodiment of the present invention has a concave bolting groove formed along the circumferential direction at an end thereof, and a serration formed along the axial direction from the bolting groove opposite to the end of the end portion. A shaft having a flat surface portion positioned from the portion and the bolt coupling groove to the end of the end portion; A yoke having a serration hole formed at one side thereof and a bolt hole formed to communicate with the serration hole in a direction perpendicular to the serration hole; And a bolt inserted into the bolt hole of the yoke and passing through the bolt coupling groove of the shaft.
As described above, according to the present invention, it is possible to prevent erroneous assembly when connecting the shaft and the yoke, and to prevent stress concentration in the bolted groove after fully assembling, thereby improving the reliability of the product and of course, It is effective to prevent the occurrence of an accident in advance.

Hereinafter, some embodiments of the present invention will be described in detail through exemplary drawings. In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used to refer to the same components as much as possible even if displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
In addition, in describing the component of this invention, terms, such as 1st, 2nd, A, B, (a), (b), can be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms. If a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected to or connected to that other component, but there may be another configuration between each component. It is to be understood that the elements may be "connected", "coupled" or "connected".

Accordingly, the
According to one embodiment of the present invention having such a structure and shape, it is possible to improve the reliability of the product as well as to prevent the occurrence of unwanted accidents in advance.
In the above description, all elements constituting the embodiments of the present invention are described as being combined or operating in combination, but the present invention is not necessarily limited to the embodiments. In other words, within the scope of the present invention, all of the components may be selectively operated in combination with one or more.
In addition, the terms "comprise", "comprise" or "having" described above mean that the corresponding component may be included, unless otherwise stated, and thus excludes other components. It should be construed that it may further include other components instead. All terms, including technical and scientific terms, have the same meanings as commonly understood by one of ordinary skill in the art unless otherwise defined. Terms commonly used, such as terms defined in a dictionary, should be interpreted to coincide with the contextual meaning of the related art, and shall not be construed in an ideal or excessively formal sense unless explicitly defined in the present invention.
The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
