The invention relates to a bidirectional overrunning clutch and an automobile power transmission system. The bidirectional overrunning clutch comprises an outer ring, an inner ring and a retainer, the outer ring comprises an outer ring body and a connecting part, the connecting part is sleeved with an outer ring bearing, the retainer comprises a retainer body, the retainer body is movably arranged in the outer ring and arranged on the inner ring in a sleeving mode, and a fixing part is arranged on the outer side wall of one end of the retainer body in the circumferential direction. A first arc-shaped positioning sliding groove and a second arc-shaped positioning sliding groove are formed in the end face of one side of the fixing part, and a first positioning ball and a second positioning ball are movably arranged in the first positioning sliding groove and the second positioning sliding groove correspondingly. And the restraining and positioning device is arranged at one end of the inner ring outside the fixing part. The bidirectional overrunning clutch has the characteristics of safety and reliability; meanwhile, the automobile power transmission system can automatically and continuously transmit power to wheels with road adhesion under the condition that speed inertia does not lose, and therefore the cross-country advancing capacity of the automobile is improved.
