Problems solved by technology
This increases the complexity of the control of the shifting device. It takes a long time to achieve synchronization between the shaft and the gear through friction, resulting in a small discontinuity in the speed during shifting, and the energy of the speed difference during the shifting process is dissipated in the form of heat energy.

The invention relates to the field of vehicle engineering, and in particular relates to a bidirectional inserting and engaging type gear shifting device which is arranged on a rotating shaft with a gear. The device comprises a jointing part, a guide sleeve, a jointing sleeve, and a flexible buffering connecting unit for transmitting circumferential power between the jointing part and the guide sleeve; the jointing part is equipped with an inserting slot; the jointing sleeve is equipped with inserting teeth; the guide sleeve comprises a guide block, a guide hole and two guide inclination surfaces; the two guide inclination surfaces are arranged on the guide block and formed by inclining from the middle part to two sides; the guide hole is formed corresponding to the inserting slot; when the flexible buffering connecting unit is in a natural extending state, the inserting slot and the corresponding inserting teeth are separated through the guide block. According to the bidirectional inserting and engaging type gear shifting device, a hydraulic control system is saved, so that the weight is light, the reaction is fast, the impact interference in gear shifting is reduced, and moreover, the number of engaging teeth can be decreased, and the structure is simplified; in addition, the mechanical semi-automatic gear shifting engaging can be achieved under a positive or negative relative speed state.
Description
technical field [0001] The present application relates to the field of vehicle engineering, in particular to a two-way plug-in engagement shift device. Background technique [0002] The gearbox expands the range of torque and rotational speed of the power source by changing the transmission ratio, makes the power source work under high power conditions under different operating conditions, and reverses the equipment when the rotation direction of the power source remains unchanged run, and interrupt power transmission through neutral selection without interrupting the power source. [0003] In the related art, the gear shifting device widely uses a synchronizer to realize gear shifting. The synchronizing effect of the synchronizer is based on the friction force of the conical friction surface between the ring gear and the synchronizing ring. In order to achieve sufficient friction, the shifting device is usually equipped with a hydraulic control system. This increases the...
