DETAILED DESCRIPTION OF THE INVENTION

[0033] FIG. 1 shows a perspective view of demounted status of driveshaft joint embodiment (100) of the invention. The invention proposes solution in the form of increasing universal joint bearing diameter (105.1) and yoke parts (102, 103) ear diameter (107) instead of increasing strength of driveshaft (101) against varying loading conditions and increasing cross body (104) arm size due to rotational diameter (106) restriction for providing placement under vehicle while performing increasing operation.

[0034] FIG. 2 shows a perspective view of detail A (Detail-A) of driveshaft joint embodiment (100) of the invention. Driveshaft (101) comprises a primary yoke part (102) and a secondary yoke part (103) functioning as connection member and housing universal joint body (104) and angle compensation. Said universal joint body (104) hosts on four arms the universal joint bearings (105) providing angular compensation on driveshaft (101). Said universal joint bearings (105) are housed to universal joint body (104) on driveshaft (101) and provide both angular compensation and interconnection of yoke parts (102,103).

[0035] Universal joint bearing diameter (105.1) is increased in order to keep rotational diameter (106) at driveshaft (101) fixed and provide increase in variable load carrying capacity coming onto driveshaft joint embodiment (100). Ear hole diameters (107) of primary yoke part (102) and secondary yoke part (103) are also increased based on increased universal joint bearing diameter (105.1). Thus it is provided to house universal joint bearing (105) and increase carrying capacity of variable load coming onto driveshaft joint embodiment (100).

[0036] In an embodiment of the invention, while universal joint bearing diameter (105.1) is increased by 4% in comparison to current related art, rotational diameter (106) remains fixed Thus keeping rotational diameter (106) fixed and increasing universal joint bearing diameter (105.1) and accordingly ear hole diameter (107) provide increase in dynamic load carrying capacity.

[0037] With driveshaft joint embodiment (100) of the invention, problem of placement under vehicle is eliminated without changing rotational diameter (106) and also variable load carrying capacity is increased.

[0038] FIG. 3 shows a two-dimension view displaying axial size (109) of driveshaft joint embodiment (100) of present related art on the left and of the invention on the right. With driveshaft joint embodiment (100) of the invention axis size (109) is decreased in comparison to present related art driveshaft. As a result of decrease in axis size (109) weight is also decreased.

[0039] FIG. 4 shows a two-dimension view displaying joint angle (110) of driveshaft joint embodiment (100) of present related art on the left and of the invention on the right. Joint angle (110) is decreased in driveshaft joint embodiment (100) of the invention. For instance, while joints used in the present related art have an angle of 25 degrees, the joint angle (110) of driveshaft joint embodiment (100) of the invention is 17 degrees. A decrease of 32% in joint angle (110) provides decrease in weight of driveshaft in the amount of 4.16-6.33 kg. Such weight decrease not only provides efficient use of sources, increase in fuel oil efficiency, decrease in environmental pollution but also decrease in production cost.
