Problems solved by technology

[0002] Current double cone lock ring synchronizers (see figure 1 ) is widely used, but in some transmissions with relatively large shift ratios, the double-cone lock-ring synchronizer has the problems of long shift time and large shift force. The structure of the three-cone synchronizer Similar to the double-cone lock-ring synchronizer, the manufacturing cost is slightly increased, and the triple-cone synchronizer has better synchronization performance and shifting convenience than the double-cone lock-ring synchronizer
The three-cone synchronizer will generate a lot of heat during synchronization due to the many friction cones. The concentration of heat will cause the ablation of the synchronous ring, reduce the wear resistance of the friction material, and accelerate the early wear of the three-cone synchronizer. and failure

Abstract

The invention discloses a three-cone synchronizer with a lubricating oil path, which comprises a sliding gear sleeve, an outer friction ring, a friction intermediate ring, an inner friction ring, a slider, a pin, a spring, a combined ring gear and a tooth hub; , a pair of combined ring gears are symmetrically arranged on both sides of the gear hub, and the conical body of the combined ring gear faces the side of the gear hub, a pair of inner friction rings are arranged on the pair of combined ring gears, and a pair of friction intermediate rings are arranged on it. The second claws of the pair of friction intermediate rings extend into the oil holes of the pair of combined ring gears, the pair of outer friction rings are arranged on the pair of friction intermediate rings, and the first claws of the pair of friction intermediate rings extend into the pair of inner friction rings In the oil groove, the sliding gear sleeve, slider, pin and spring are all arranged between a pair of outer friction rings, and one end of the pin passes through the slider to match the sliding gear sleeve, and the other end of the pin is connected to the gear hub through the spring. touch. Compared with the double-cone synchronizer, the three-cone synchronizer of the present invention has shorter shift time, smaller shift force, comfortable operation and long service life.
