Problems solved by technology

At present, the shifters used for dual-clutch automatic transmissions on the market are cable full-stroke shifters, that is, each time the shift lever passes through a gear, the shift cable moves a certain distance accordingly. The principle of this kind of shifter Consistent with the shifter used for dual-clutch automatic transmissions, it can be seen that there is no specific shifter for dual-clutch automatic transmissions in the prior art

Abstract

The invention provides a gear shifter used for a double-clutch automatic transmission. The gear shifter comprises a gear shifting rod component, a gear shifting rod and a stay rope connecting swing rod, the gear shifting rod component comprises a first portion and a second portion which are in bending relation, a positioning portion which extends downwards is arranged at the tail end of the second portion, the gear shifting rod component can rotate around a first rotating center arranged at the tail end of the first portion, the gear shifting rod is connected with the gear shifting rod component, the stay rope connecting swing rod is provided with a groove used for containing the positioning portion, and a second rotating center, one of planes adjacent to the groove serves as a sliding plane for the positioning portion to slide on, the stay rope connecting swing rod can rotate around the second rotating center arranged at the bottom of the stay rope connecting swing rod, enables a gear shifting stay rope connected with the stay rope connecting swing rod to have stroke output and is used for realizing an R-gear or a P-gear of the gear shifting rod, and when being on the sliding plane, the positioning portion is used for realizing other gears of the gear shifting rod. By the brand-new technical scheme, the gear shift is not a stay rope full-stroke-type shifter any more, so that stay rope consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a shifter for a double-clutch automatic transmission. Background technique [0002] As a new type of automatic transmission, dual clutch automatic transmission (Dual Clutch Transmission, DCT) combines the advantages of high transmission efficiency, simple mechanism, good production inheritance and low manufacturing cost of electromechanical mechanical transmission (Automatic Manual Transmission, AMT). And automatic transmission (Automatic Transmission, AT) power shift advantages, with good shift quality and vehicle dynamics, economy. [0003] With the increasing development of the automobile industry, dual-clutch transmissions are increasingly used in vehicles. A need therefore arises to develop a shifter for a dual clutch automatic transmission. At present, the shifters used for dual-clutch automatic transmissions on the market are cable full-stroke shifters, that is, each...
