Description

A SLIP ASSY CONFIGURATION FOR DRIVESHAFT
Technical Field
The invention relates to a modification of the slip assy on motor vehicles that compensates for the length of the driveshaft during the movement of the vehicle.
Particularly, the invention relates to a slip assy configuration with a strengthened shank section to prevent the yoke shaft from being twisted and from permanent deformation.
Prior Art
Driveshafts are used in motor vehicles to transmit the rotational motion and the power generated in the engine to the vehicle’s differential from the engine or the transmission to move the vehicle.
Driveshafts also regulate the angular displacement between the transmission and axle assemblies and the longitudinal displacement changes caused by the movement of the axle assembly due to the movement of the vehicle’s suspension. These axial length variation requirements are typically met using a slip assy assembly. The said slip assy consists of a yoke shaft and a tube sleeve. The yoke shaft and the tube sleeve are the driveshaft unit elements that work mutually with each other as matched elements. The yoke shaft has a male spline form on its outer diameter, while the tube sleeve has a female spline form on its inner diameter. The torque coming from the engine is transferred by means of mutually complementary this spline form.
In the applications in the prior art, yoke shaft is twisted from its portion called shank diameter and that portion can be subjected to permanent deformation.
In the literature research, the utility model application numbered CN202118143U was found. The application relates to a new splined yoke shaft. In the said document, it is mentioned that an outer edge of the splined yoke shaft is provided with an outer spline and its inner wall is provided with an inner spline. However, in the said application, there is no mention of any structural design changes made specifically on the form of the yoke shaft shank and the tube end form.
In the research conducted in the technique, the patent application numbered EP2990677B1 was found, which is related to the front scraping feature sealing structure that prevents separation in the slip assy elements of the driveshafts. In the said application document, it is mentioned that the sliding yoke with spline form positioned on its inner diameter and the stop lug on the outer surface end, yoke shaft with spline form on the outer diameter and it is positioned on the said yoke shaft. However, there is no mention of any structural design changes made specifically in the yoke shaft shank form and the tube sleeve end form.
The patent application numbered US5716276A relates to a light and durable vehicle drive shaft assembly, particularly the yoke shaft for the drive shaft assembly. In the application document is mentioned to vehicle drive shaft assemblies for power transmission in a vehicle and, in particular, a yoke shaft developed to allow torque transmission and axial displacement in a drive shaft assembly. In the said document is mentioned a yoke shaft formed from aluminium or an aluminium alloy with splines matched with the splines of an aluminium tube to transmit rotational force. However, in the said application, there is no mention of any structural design changes made in the form of the yoke shaft shank and the tube end form.
Therefore, the existence of the above problems and the inadequacy of the existing solutions made it necessary to make an improvement in the related technical field.
Purpose of the Invention
The invention relates to a yoke shaft with a strengthened shank diameter that meets the requirements and eliminates all the disadvantages mentioned above and provides some additional new advantages.
The main purpose of the invention is to provide a product with a strengthened shank diameter to prevent the yoke shaft from being twisted at the portion called shank diameter and to prevent permanent deformation from that part, to increase the low strength level. In order to realize all the advantages mentioned above as will be understood from the detailed description below, the invention is a slip assy configuration of yoke shaft with strengthened shank section and tube sleeve on the driveshaft, which gives movement to the vehicle by transmitting the rotational motion and power of the engine in motor vehicles, characterized by comprising:
• yoke shaft shank form (1.3) that is designed such that the yoke shaft shank diameter (Dm) is smaller than the tube sleeve end diameter (Dk)
• tube sleeve end form (1.4) designed to be larger than the thread minor diameter (Dt) of the tube end diameter (Dk) by removing the spline form at the tube end depending on the yoke shaft shank form (1.3).
The structural and characteristic features of the invention and all its advantages will be understood more clearly by means of the figures provided below and the detailed explanation written with reference to these figures, and therefore the evaluation should be made by taking these figures and detailed explanation into account.

Detailed Description of the Invention
In this detailed description, preferred alternatives of the invention are explained only for the purpose of providing a better understanding of the subject and in a manner that does not create any limiting effect.
The invention is a slip assy configuration (1) with strengthened shank section consisting of tube sleeve (1.2) and yoke shaft (1.1) on the driveshaft, which gives movement to the vehicle by transmitting the rotational motion and power of the engine on motor vehicles characterized by comprising; a yoke shaft shank form (1.3) for the purpose of increasing the strength of the slip assy (1), where the yoke shaft shank diameter value (Dm) is designed in a such way so as not to prevent the axial movement of the from the tube sleeve end diameter (Dk) and a tube sleeve end form (1.4) designed to be larger than the thread minor diameter (Dt) of the tube end diameter (Dk) by removing the spline form at the tube end, depending on the sleeve yoke shaft shank form (1.3).
Figure 1 and Figure 2 illustrate the view of the slip assy with strengthened shank section, assembly on the driveshaft. The strengthening, which is the subject to the invention, includes strengthening the shank part of the yoke shaft (1.1) with a design change and depending on this design change, making a design change in the end part of the tube sleeve (1.2). In this way, the low strength level in the shank diameter is increased.
The cross-sectional and exploded cross-section views of the slip assy (1) with strengthened shank section of the invention are given in Figure 3 and Figure 4, respectively. For the said strengthening, the spline form is removed from the end diameter (Dk) of the tube sleeve (1.2) and the tube end diameter (Dk) is formed so that it is larger than the thread minor diameter (Dt). The Yoke shaft shank diameter value was named as Dm. The specified Dm diameter value is formed as smaller than the end diameter (Dk) value of the tube sleeve (1.2) so that it conforms to the form provided in the slide tube (1.2) and does not interfere with its axial movement. Yoke shaft (1.1), which is one of the parts that create the sliding group of the driveshaft, can be damaged in this region due to the high stress distribution in the shank part. To find a solution to this problem, a new form was created in the shank section of the part. A new form of Yoke shaft (1.1) is shown in the shank section of the structure, which is the subject of the invention, in Figure 5. A new form was created at the end of the tube sleeve (1.2), which is the mounting counter piece, in order to adapt to the new form introduced for strengthening in the form of Yoke shaft. The tube sleeve (1.2) in which a new form is formed at the end of the structure, which is the subject of the invention is shown in Figure 6.
