Synchronizing device, synchronizing device speed control system and vehicle

Abstract

The invention provides a synchronizing device, a synchronizing device speed regulating system and a vehicle, and relates to the technical field of vehicles. The synchronizing device comprises a gear and an output shaft. A friction plate groove is formed in the inner ring of the gear. The output shaft is provided with an oil inlet hole with a sealed end and an oil outlet hole communicating with theoil inlet hole. The outer side of the output shaft is connected with a friction plate. The output shaft is arranged on the inner ring of the gear, and the friction plate is clamped on the friction plate groove. Hydraulic oil entering the output shaft from the oil inlet hole enters the friction plate groove from the oil outlet hole to push the friction plate, so that friction force is formed between the friction plate and the side wall of the friction plate groove, and the gear and the output shaft are synchronized. The synchronizing device is compact and simple in structure, and layout spaceis saved. According to the synchronizing device, mechanical devices (gear hubs, gear sleeves, soldered teeth and synchronizing rings) are omitted, secondary impacts are reduced, and mechanical noise of the end faces of the soldered teeth of a gear sleeving machine is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a synchronizing device, a speed regulating system of the synchronizing device and a vehicle. Background technique [0002] Today's automobile industry takes energy saving and emission reduction as the development direction. The transmission shifting system plays a key role in fuel economy, and the synchronizer affects the smoothness / comfort of shifting, thereby affecting the quality of shifting; especially shifting shock and NVH Noise index is one of the necessary conditions for customer evaluation; light weight, integration, miniaturization, intelligence, excellent space layout and reduction of shifting shock and NVH noise of shift system components have become the mainstream trend in the development process of dual clutch transmissions . The structure of the synchronizing device currently used is complex, the degree of integration and intelligence is low, and a mechanical imp...
