Abstract

The invention relates to an electric control gear shifting auxiliary device for an automobile manual transmission. The electric control gear shifting auxiliary device consists of grooves and shifting blades, wherein the grooves are formed by shifting fork rods of the automobile manual transmission and interval parts between the shifting fork rods; the length of each groove is slightly greater than a gear shifting travel distance of each two gears, which is controlled by the shifting fork rods; and the shifting blades are fixedly arranged at shifting rod groove bottoms and at the midpoint positions in the length direction of the grooves at intervals of one shifting fork rod from a second shifting fork rod or a first shifting fork rod and extend into the adjacent shifting rod grooves. By the shifting between the shifting blades and shifting fork rod groove front and rear walls in the gear shifting process, the synchronization of shifting forwards and shifting backwards is implemented in the process of electrical control gear shifting process of the manual transmission and the gear shifting process is accelerated.

Description

The automatically controlled gearing auxiliary device of manual gear of vehicle

Art

The present invention relates to a kind of gearing auxiliary device of manual gear of vehicle, make manual gear of vehicle when automatically controlled gearshift, two adjacent gears, can enter gear with move back keep off synchronous, quickening shift process.

Background technique

At present, known manual gear of vehicle is when switching gear, and after a upper gear must retreat to neutral, next gear just can enter, and the gearshift time is longer, causes certain power loss, and brings certain technical barrier to automatically controlled gearshift.

Summary of the invention

In order to overcome manual gear of vehicle shift gears time on a gear must retreat to neutral, next gear just can enter, be difficult to the deficiency of automatically controlled gearshift, the present invention proposes the automatically controlled gearing auxiliary device of a kind of manual gear of vehicle, make manual gear of vehicle when automatically controlled gearshift, two adjacent gears can be accomplished, enter gear with move back keep off synchronous, quickening shift process.

The technological scheme that technical solution problem of the present invention adopts is: first, traditional for manual gear of vehicle interlock is removed, then, at all shifting fork bar of manual gear of vehicle together with the apart section between shifting fork bar and shifting fork bar, when all gears are neutral gear position, make groove or hole that a length is a bit larger tham two gear gearshift stroke distances that shifting fork bar controls, width runs through all shifting fork bar together with the apart section between shifting fork bar and shifting fork bar, upper and lower four walls in front and back of a groove-bottom and former and later two groove walls or hole will be formed like this at each shifting fork bar, from the second shifting fork bar or the first shifting fork bar, at interval of a shifting fork bar, at shifting fork bar bottom portion of groove, the point midway of groove length or the point midway of hole front and rear wall spacing, the plectrum that front and rear wall spacing that length that a width is shifting fork bar groove deducts two gears gearshift stroke distances that shifting fork bar controls or hole deducts two gears gearshift stroke distances that shifting fork bar controls is installed, plectrum is vertical with the y direction of shifting fork bar and stretch in the adjacent shifting fork bar groove of shifting fork bar therewith or in shifting fork bar is adjacent therewith shifting fork bar hole, plectrum is parallel with lower wall on bottom portion of groove or hole and leave certain interval, plectrum and bottom portion of groove or hole upper and lower wall friction during to avoid gearshift, increase gearshift resistance.When automotive transmission advance gear is more, shifting fork bar quantity more than four time, the length that the plectrum that shifting fork bar is installed extend in the shifting fork bar groove or hole that are adjacent should be slightly smaller than the radius of shifting fork bar or take layering to arrange, interference is produced when shifting gears to prevent two plectrums extend in a shifting fork bar groove or hole simultaneously, when automatically controlled gearshift, by mutually stirring between the front and rear wall of shifting fork bar groove front and rear wall or hole and plectrum, make the adjacent gear of speed changer two realize into gear with move back keep off synchronous, accelerate shift process.

The invention has the beneficial effects as follows: can on the basis of manual transmission, transform a little, realize the automatically controlled gearshift function of manual transmission, accelerate shift process, reduce power loss, compared with traditional automatic transmission, reduce manufacture cost, saving fuel oil, also can prevent the adjacent gear of speed changer two from running the damage caused speed changer simultaneously.
