DESC:[001] The present disclosure generally relates to a crown pinion system with amboid offset for rear axle in 458DH. More particularly, the present disclosure relates to the crown pinion system with amboid offset and method of manufacturing thereof.
[002] Currently crown pinion designed with hypoid offset (i.e. below the center pinion) in rear axle drive head assembly has certain functional design limitations or drawbacks such as higher driveline angles, less life of driveline component, high torsional vibrations result into noisy system.
[003] Further the existing system has certain challenges to overcomes above challenges as the design of hypoid offset (i.e. below the center pinion) having offset of 44.45mm with respect to drive head center lead to propeller shaft angle with frame horizontal plane higher and leaving no room for design modification efficiently. Hence the life of system is less and having noisy operation. To avoid above ignorance mistakes of driver, a robust system needs to design to avoid or overcome such mistakes of driver with an alert mechanism.
[004] Therefore, there is an unmet need to find an alternate low-cost robust crown pinion designed with hypoid offset (i.e. below the center pinion) in rear axle drive head to avoid or overcome above-mentioned and allied challenges and disadvantages.
[005] The present invention solves the aforementioned and other allied problems by the way of providing crown pinion designed with hypoid offset having optimal driveline angle with lesser angle as compared to existing system. It can be possible by integrating pinion offset in such a manner that it decreases the height of pinion point with respect to vehicle frame resulting in decrease in drive shaft angle.
[006] The use of amboid offset (i.e. above the center pinion) system resulting into decrease in driveline angle. The presence of amboid gearing system provide noisy less smooth system. Since driveline component designs are mainly derived through driveline angle, decrease in angle is enabling us to optimize the component designs and their life. It also providing less torsional vibrations.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[009] The present invention relates to the crown pinion system with amboid offset for rear axle In 458DH.
[0010] Referring to FIG. 1 disclosing crown pinion system with amboid offset for rear axle in 458DH. The crown pinion designed with hypoid offset having optimal driveline angle with lesser angle as compare to existing system. It can be possible by integrating pinion offset in such a manner that it decreases the height of pinion point with respect to vehicle frame resulting in decrease in drive shaft angle. Further the use of amboid offset (i.e. above the center pinion) system resulting into decrease in driveline angle. The presence of amboid gearing system provide noisy less smooth system. Since driveline component designs are mainly derived through driveline angle, decrease in angle is enabling us to optimize the component designs and their life. It also providing less torsional vibrations.
[0011] Although the present disclosure is described in terms of certain preferred embodiments and examples, other embodiments and examples will be apparent to those of ordinary skill in the art, given the benefit of this disclosure, including embodiments and examples that do not provide all of the benefits and features set forth herein, which are also within the scope of this disclosure. It is to be understood that other embodiments may be utilized, without departing from the true spirit and scope of the present invention.
