Chris Evert Lloyd, saying she thought the omens were with her, won her third Wimbledon singles title today, defeating Hana Mandlikova of Czechoslovakia, 6-2, 6-2. Mrs. Lloyd's surprisingly easy victory was achieved in only 60 minutes, before a capacity center-court crowd of 14,000 that included the Duke and Duchess of Kent, Lady Diana Spencer, the fiancee of Prince Charles, and Margaret Thatcher, Britain's Prime Minister. The victory capped a stunningly successful tournament in which Mrs. Lloyd swept all seven of her matches in straight sets, the first such clean slate by a women's singles champion here since Billie Jean King did it in 1967. ''I was determined to win it this year,'' said Mrs. Lloyd, who was runner-up the last three years and who, at 26 years of age, was playing in her seventh final since she first played at the All-England Club in 1972. ''I know when I'm determined I'm still the best,'' Mrs. Lloyd said. ''I proved it at the U.S. Open last year and I proved it here.''

A subway motorman was killed and more than 135 passengers were injured yesterday afternoon when a Manhattan-bound train plowed into the rear of a second train halted for signal trouble in a darkened tunnel in Brooklyn. The motorman, Jesse Cole, a 36-year-old resident of the Bronx who had worked for the Transit Authority for 11 years, was trapped in the twisted wreckage of his cab for four hours after the crash. Authorities said he died about an hour before rescue workers extricated his body shortly before 6 P.M. Passengers told of having seen Mr. Cole through the shattered window of his cab. ''He was groaning and moaning, and saying: 'Help, help, get me out! I'm dying,' '' recalled one witness, Joe Lopez. ''His head was covered with blood,'' Mr. Lopez added. ''We felt so helpless. There was nothing we could do for him.''

Western diplomats here say they are now less pessimistic about the chances of Soviet military intervention in Poland. The assessment came as Andrei A. Gromyko, the Soviet Foreign Minister, flew to Warsaw today for what was described as a ''friendly'' visit. The diplomats' view is reinforced by a notable reduction in the volume and stridency of Soviet press criticism of Poland in recent days, suggesting that the Russians were still some way from the point at which they might decide to intervene militarily or otherwise thwart Poland's push for economic and political changes. Mr. Gromyko's trip was apparently linked to a special gathering of the Polish Communist Party set to open in Warsaw on July 14. Although the policy-making process in the Kremlin remains largely impenetrable, the most credible interpretation of recent pronouncements supports the view that the Soviet leaders are still hoping that the specter of Soviet tanks, coupled with stiff warnings against the unraveling of Communist power, will be enough to uphold essential Soviet interests.

Mayor Koch said yesterday that Governor Carey had ''lost control'' of the mass-transit negotiations in Albany. Mr. Carey, in turn, accused the Mayor of playing politics with New York City subway and bus fares. The remarks, which came in separate telephone interviews, were among the sharpest to date between the two Democratic leaders in what Mr. Koch characterized as ''a growing breach.'' ''He's no longer in command up there,'' the Mayor said of Mr. Carey. ''He was totally unable to deliver a legislative package. He has the worst relations with legislative leaders - the worst.''

The Navy has proposed a vast shipbuilding and aircraft procurement plan that is intended to meet President Reagan's goal of attaining a clear margin of naval superiority over the Soviet Union before the end of this decade. The plan includes two nuclearpowered aircraft carriers, 14 attack submarines and nearly 1,900 airplanes. Senior Pentagon officials said that the program, which seems likely to be approved by the Administration with only minor changes, would require that over five years Congress authorize about $120 billion in spending as measured in 1982 dollars. Some of the actual outlays would come after the five-year period.
