The invention relates to a shift-down reinforcing lock ring type inertial synchronizer and belongs to the technical field of inertial synchronizers. The shift-down reinforcing lock ring type inertial synchronizer comprises a synchronizer slide sleeve, a synchronizer gear hub, a leaf spring, a pusher, a synchronizer cone hoop and a combined gear ring. A first notch is formed in the excircle surface of the synchronizer gear hub, a pushing claw is arranged on the pusher, and a carrying surface is arranged on the pushing claw; the leaf spring is mounted between the synchronizer gear hub and the pusher, and the big end of the leaf spring is in contact with the pusher; a spline tooth and a short locking tooth are arranged on the inner circle surface of the synchronizer slide sleeve, and the short locking tooth is used for being matched with the carrying surface on the pushing claw; the synchronizer cone hoop is located on one side, far from the synchronizer gear hub, of the pusher, and is coaxially mounted with the synchronizer gear hub, and the combined gear ring is located on one side, far from the synchronizer gear hub, of the synchronizer cone hoop, and is coaxially mounted with the synchronizer cone hoop. In a shift-down process, energy is pre-stored in the leaf spring first, and then shift-down reinforcement is finished by means of energy released by the leaf spring.
Description
technical field [0001] The invention relates to the technical field of inertial synchronizers, in particular to a reverse gear booster lock ring type inertial synchronizer. Background technique [0002] Synchronizer is the main component to improve the shifting performance of mechanical automobile transmission, and it makes a great contribution to reducing the labor intensity of the driver, improving the portability of operation and the average life of the components of the transmission transmission system. [0003] At present, there are many types of synchronizers at home and abroad, and there are also many researches on gear booster synchronizers that speed up the synchronization process and reduce the gear force, such as self-boosting Porsche synchronizers, but shorten the time for retracting, There is less research on the reverse gear booster synchronizer that reduces the reverse gear force. However, in the actual working process of the transmission, the reverse gear is...
