Problems solved by technology

[0004] In the current component connection technology, the frictional synchronization method is mainly used to reduce the impact. For example, the synchronizer in the engine clutch and the transmission adopts the frictional method to synchronize the components at both ends of the connection mechanism. However, due to the structural limitations of the friction mechanism, it is impossible to Determine the phase angle correspondence between the components at both ends of the connecting mechanism at the time of final synchronization

Abstract

The invention discloses a gearshift mechanism with a unique phase angle and a control method thereof. The gearshift mechanism comprises a motor, a first shaft, a second shaft, a gear hub and a gear sleeve. The gear hub is rigidly arranged on the first shaft or the second shaft. The gear sleeve is coaxially arranged outside the gear hub and connected with the gear hub in a sliding manner through a spline. An output shaft of the motor is fixedly connected with the first shaft or the second shaft. The gearshift mechanism further comprises at least one phase angle synchronizing assembly. Each phase angle synchronizing assembly comprises a combining tooth and a synchronizing ring, wherein the combing tooth is connected with the first shaft or the second shaft in a transmission manner. The combining teeth, the synchronizing rings and the gear hub are coaxially arranged. Each synchronizing ring is arranged between the corresponding combining tooth and the gear hub. When the gear sleeve slides to the combing teeth, the synchronizing rings can be driven to compress the combining teeth, and the combining teeth and the gear sleeve are made to tend to rotate at the same speed; after the combining teeth and the gear sleeve rotate at the same speed, the synchronizing rings can be disengaged from the combining teeth; and after the synchronizing rings are disengaged from the combining teeth, the gear sleeve can be connected with the combining teeth at the position of the set unique phase angle.

Description

Technical field [0001] The invention relates to the technical field of vehicle transmission systems, in particular to a gear shifting mechanism with a unique phase angle for an engine. Background technique [0002] In the engine system, each cylinder completes the intake, compression, work, and exhaust processes in sequence according to the set sequence. In order to ensure that each cylinder completes each work in strict accordance with the set sequence, two camshafts are usually used to control the intake and exhaust of each cylinder, and a crankshaft is used to receive the power of each cylinder. [0003] In order to reduce energy consumption, engine cylinder deactivation technology has emerged, which starts up a corresponding number of cylinders according to the demand for engine power. Since each cylinder has a strict phase angle correspondence relationship, when restarting and stopping the cylinder, not only the cylinder must be driven to run, but also the phase angle between...
