Three-conical-face synchronizer with lubricating oil way

Abstract

The invention discloses a three-conical-face synchronizer with a lubricating oil way. The three-conical-face synchronizer comprises a sliding gear sleeve, external friction rings, middle friction rings, internal friction rings, a sliding block, a pin, a spring, combined gear rings and a gear hub. A pair of the combined gear rings are symmetrically arranged on the two sides of the gear hub, and conical face bodies of the combined gear rings face one side of the gear hub. A pair of the internal friction rings are arranged on the combined gear rings and provided with a pair of the middle friction rings. Second claws of the middle friction rings extend into oil passing holes of the combined gear rings. A pair of the external friction rings are arranged on the middle friction rings. First claws of the external friction rings extend into oil passing grooves of the internal friction rings. The sliding gear sleeve, the sliding block, the pin and the spring are arranged between the external friction rings. One end of the pin penetrates through the sliding block and is matched with the sliding gear sleeve, and the other end of the pin makes contact with the gear hub through the spring. Compared with a double-conical-face synchronizer, the three-conical-face synchronizer is shorter in shift time, smaller in shift force, more comfortable to control and longer in service life.

Description

【Technical field】 [0001] The invention belongs to the field of automobile transmission devices, and in particular relates to a three-cone synchronizer with lubricating oil passages. 【Background technique】 [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 ...

[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
