Differential device including a differential gear 4 and a differential gear box monolithic

摘要

Differential, the present invention relates to a differential device for use in a power transmission system of a motor vehicle in particular. With differential gear box structure (3) together, and are adapted to be rotatably driven about axis of rotation (A), the differential device, the differential gear box assembly opening (26) peripheral wall portion has a bearing additional portion which is integrally formed on the end portions of the opposing both and has a (16); further comprising axles gears multiple (9, 10), the assembly opening axle gear (16) It includes a differential gear 4 (8); through is inserted differential gear box (3) inside, and is held differential gear box (3) in so as to be rotatable about axis of rotation (A) is inserted differential gear box (3) within the assembly through the opening (16), have engaged with the (9, 10) axle gear, along with the differential gear box rotation axis differential gear, the (A) It is adapted to be by orbital motion around; includes cross pin member out of a number of (17, 18, 19, 20) four pins (7), the differential gear box cross pin member (3) It is drivingly connected in the circumferential direction, and holds the differential gear of one (8) respectively, two, four pins are inserted into the assembly opening through (16), at least one of the differential gears 4 are adapted to.
