摘　　要：为实现电控机械式自动变速器(AMT)在升挡过程中对发动机以及变速器1轴的减速,使变速器目标挡位齿轮与输出轴同步最终实现换挡,文章设计了一种安装于变速器上的气动制动器。通过对变速器中间轴进行制动,实现减速升挡。安装试验结果表明,该气动制动器满足了在升挡过程中对发动机以及变速器1轴的减速要求。该制动装置具有结构简单及响应快速的特点,有效提高了换挡品质。In order to achieve deceleration of engine and I shaft of electro-mechnical automatic transmission in upshift process,and target gear and output shaft synchronized shifting,a kind of pneumatic brake mounted on the transmission is designed.By braking on transmission countershaft,deceleration and upshift is achieved.The test results show that this pneumatic brake meets the requirements of deceleration of engine and I shaft in upshift process.This device has the characteristics of simple structure and quick response.Upshift is improved effectively.
