Description

一种改进油泵布置结构的双离合变速器A Dual Clutch Transmission with Improved Oil Pump Arrangement Structure

技术领域 technical field

本发明属于变速器的结构设计领域，具体涉及一种改进油泵布置结构的双离合变速器。 The invention belongs to the field of structural design of transmissions, and in particular relates to a double-clutch transmission with an improved arrangement structure of an oil pump.

背景技术 Background technique

近些年来随着我国汽车产业的迅速发展，人们对汽车性能的要求越来越高，而变速器对汽车的性能起着至关重要的作用。油泵是变速器的重要组成部分，获得动力的油泵将油箱内的油输送到变速器内，为变速器中的机械部件提供润滑油液、实现换挡液力操作、向液压控制系统提供油液压力。 With the rapid development of my country's automobile industry in recent years, people have higher and higher requirements for automobile performance, and the transmission plays a vital role in the performance of automobiles. The oil pump is an important part of the transmission. The powered oil pump transports the oil in the oil tank to the transmission, provides lubricating oil for the mechanical parts in the transmission, realizes the hydraulic operation of gear shifting, and provides oil pressure to the hydraulic control system.

目前双离合变速器中油泵的布置方式主要分为输入轴始端布置和输入轴末端布置的方式，增加了变速器的轴向尺寸。同时这些布置方式中油泵动力都是由发动机直接提供，占用了发动机的输出能耗，使得变速器的传动效率直接降低了10%。现在变速器使用的内啮合齿轮油泵多采用渐开线齿轮泵、摆线齿轮泵和圆弧齿轮泵，排量、流量脉动等均不能达到最好的要求。 At present, the arrangement of the oil pump in the dual-clutch transmission is mainly divided into the arrangement of the beginning of the input shaft and the arrangement of the end of the input shaft, which increases the axial size of the transmission. At the same time, the power of the oil pump in these arrangements is directly provided by the engine, which takes up the output energy consumption of the engine and directly reduces the transmission efficiency of the transmission by 10%. At present, the internal gear oil pumps used in transmissions mostly use involute gear pumps, cycloid gear pumps and arc gear pumps, and the displacement and flow pulsation cannot meet the best requirements.
