Abstract

The invention provides a magnetic synchronizer and a transmission. The magnetic synchronizer comprises a gear hub, a joint sleeve, a first magnetic piece and a second magnetic piece, wherein the gearhub is used for being coaxially connected with an output shaft; the joint sleeve is coaxially arranged on the gear hub in a sleeving mode and used for freely sliding in the axial direction of the gearhub when being driven by external force; a plurality of N poles and S poles which are arranged in a staggered manner are arranged on the first magnetic piece, and the first magnetic piece is used forbeing fixedly connected with an idle gear which idles on the output shaft; the second magnetic piece is fixedly connected with the joint sleeve, and a plurality of N poles and S poles which are arranged in a staggered manner are arranged on the second magnetic piece; and when the magnetic synchronizer is used for gear shifting operation, a magnetic field generated by the first magnetic piece is matched to drive the joint sleeve and the idle gear to rotate synchronously. The magnetic synchronizer provided by the invention has no noise, and the structure of the synchronizer cannot be abraded; and friction is not generated in the gear shifting process, and the gear shifting speed is improved. The magnetic synchronizer also has the characteristics of low cost, convenient manufacture and longservice life.

Description

technical field [0001] The invention belongs to the technical field of transmission, and more specifically relates to a magnetic synchronizer and a speed changer. Background technique [0002] Existing synchronizers for automobile gearboxes include normal pressure type, inertia type, and self-energizing type. At present, the inertial synchronizer is the most widely used. The inertial synchronizer is mainly composed of an adapter sleeve, a synchronous lock ring, etc. It is characterized by relying on friction to achieve synchronization, and its disadvantage is that noise will be generated during the friction process; synchronizer The inner and outer tapered surfaces of the synchronizer will be continuously worn during the working process, which will shorten the service life of the synchronizer. Contents of the invention [0003] The purpose of the present invention is to provide a magnetic synchronizer, aiming to solve the technical problems of short service life of existi...
