This design will affect the stability of the transmission Effect; and when the axis offset of the wheel axle (2 0) (2 0,) (as shown by arrow A) is not on the same axis line, or the differential gear (9) (9,) and the transmission gear (1 〇) (i 〇,) There is a gap between the two, which will cause the differential gear (9) (9,) and the transmission gear (1 〇) (1 〇 ') are not fully combined to make the differential function. Failure, unless all its components are completely in close cooperation to produce stable state energy, but in terms of mechanical assembly, there is a certain gap more or less, and when the differential gear (9) (9 ') and the transmission gear ( ; [0] (丄 〇,) when there is a gap between the 'the differential gear (9) (9') extremely easy too #, hurriedly generated between the transmission gear (1 0) (1 0 '), formed to The phenomenon of bumping into the +, and thus the noise of Yan Yan; In addition, its design adopts the shape coupling method ,,,, and installation, although the default is called bolts, but when replacing small parts, it may make… $ position, must Reassemble and adjust it once again, increase the number of parts on the skirt, and more importantly, the active gear of this differential is complicated. The wheel (8) and the input side 5 M275975 The wheel (1 9) is housed in a differential case. The speed ratio between the input gear (i 8) and the active animal wheel (8) cannot be adjusted. When the wheel axle (2㈡ (2 0 ') The torque transmitted when the size of the connected tire needs to be changed will change. At this time, the speed ratio of the differential will not be able to meet the user's needs. Therefore, the operator must adjust according to the user's specific torque requirements. A specific differential is ordered with an appropriate speed ratio, so its variability is poor, and it cannot be applied to various types of vehicles, such as popular ATVs, electric vehicles, and scooters.... In view of the currently used differentials, There is still room for improvement in use. Therefore, the author uses many years of research and development and manufacturing experience in related industries to discuss the problems faced by the existing differentials mentioned above, and actively seek solutions to them. After several tests and improvements, a differential that can truly improve the above-mentioned defects has finally been created.
