Description
Technical field
The utility model belongs to the automotive transmission technical field, relates in particular to a kind of automobile six shift transmission gearshifts.
Background technique
The working principle of automotive transmission is through changing the excursion that transmission recently changes the automobile driving force and the speed of a motor vehicle; To satisfy automobile cruising under various road conditions conditions; Along with the continuous progress and development of automotive engineering, people to automobile drive sense and shift of transmission quality require increasingly high.
At present, manual transmission is in the majority with five-gear manual transmission, a gearshift of its gearshift employing shifting block, and an interlock board and two helical spring structures layouts because of the 5-R retaining is arranged in a side, need to design the lock that reverses gear, general nothing gearshift guide mechanism; The moving speed changer of six blocks has two kinds of twin axle and triple axles, and the twin axle structure is identical with existing five-gear manual transmission structure, realizes six retainings through increasing by one group of gear, adopts an input shaft and a jack shaft (being also referred to as output shaft sometimes).The twin axle shifter of transmission adopts a gearshift shifting block, and each keeps off shifting block and is arranged side by side together.In order to shorten axial distance as much as possible, be convenient to car load and arrange that people have developed new triple axle structure; This triple axle structure adopts an input shaft and two jack shafts (also claiming double output shaft or two jack shaft sometimes), owing to increased a jack shaft, makes the speed changer inner space very limited; Gearshift is arranged very difficulty, because two jack shafts arrange that distance is bigger, the structure that can't be through shift fork or shifting block and the layout of declutch shift shaft realize respectively keeping off shifting block and be arranged side by side together; Need two shifting blocks of design this moment, realize six gear gear shift operation, in order to guarantee the interlocking and can realize the guide function of shifting gears reliably of each gear; The quantity of part increases, and makes gearshift complicated, is not easy to assembling; And the space is big; Cost is high, and is limited because of the speed changer inner space again, and gearshift is easy to interfere with part around other.
In the moving speed changer of many blocks, normally adopt the interlock board structure, realize the interlocking between gear.Interlock board together is connected on the gearshift axle with the gearshift shifting block; The gearshift shifting block is fixed through pin or key and gearshift axle; Interlock board positions through pin or bolt or other modes that is fixed on the housing, prevents that it from rotating along axis, and the gearshift axle drives a gearshift shifting block and can rotate freely.When gearshift, interlock board is locked in neutral to not selected gear, and the shifting block that prevents to shift gears is stirred the gearshift shifting block of two gears simultaneously or the phenomenon of disorderly keeping off or trip stop in the running process, occurred.And the self-locking of speed changer normally is employed in and opens three grooves on the declutch shift shaft, utilizes self-locking steel ball and self-locking spring to accomplish the self-locking of this gear.Design two shifting blocks, realize six gear gear shift operation, in order to guarantee each gear interlocking and the guide function of realizing shifting gears reliably; The quantity of part increases, and makes gearshift complicated, is not easy to assembling; And the space is big; Cost is high, and is limited because of the speed changer inner space again, and gearshift is easy to interfere with part around other; Design a shifting block, realize six gear gear shift operation, in order to guarantee the interlocking and can realize its function reliably of each gear; Need shifting block be arranged side by side together, because of the arrangement of gears reason, synchronizer and declutch shift shaft centre distance are bigger; Cause shift fork and shifting block cantilever longer, shift fork insufficient rigidity, the excessive influence gearshift of distortion are carried out smoothly, and there is tilting moment in the gearshift shifting block when stressed; The gearshift resistance is increased, the gearshift catching phenomenon occurs.
The model utility content
Be to solve the deficiency that exists in the existing technology, the utility model provides that a kind of number of spare parts is few, the automobile six shift transmission gearshifts of gearshift light and flexible, compact structure, can guarantee that speed changer gets into arbitrary gear work accurately and reliably.
For realizing above-mentioned purpose; The automobile six shift transmission gearshifts of the utility model; Comprise gearshift axle, be fixed on the first gearshift shifting block that one to four retaining gear shift operation was gone up, was used for to the gearshift axle, be fixed on that the gearshift axle is gone up, is used for five, six, second a gearshift shifting block of the operation of reversing gear; Cover the gearshift guide mechanism that has guiding groove that is connected with gearshift; The guide finger of the described first gearshift shifting block is limited in the guiding groove, and to the interlock board that gear locks, described interlock board is sleeved on the gearshift axle; It has first accommodating part and second accommodating part that holds the first gearshift shifting block and the second gearshift shifting block, described gearshift guide mechanism through with interlock board be connected the restriction interlock board along a gearshift axle axial rotation.
As qualification to aforesaid way; The end of described gearshift guide mechanism is provided with elbow; On first accommodating part of interlock board, be provided with and elbow along the elongated slot of gearshift axle axial sliding fit, this elongated slot with limit interlock board cooperating of elbow along a gearshift axial rotation.
As further qualification to aforesaid way; Described interlock board is respectively equipped with gap on first accommodating part and second accommodating part; The shifting block of the first gearshift shifting block and the second gearshift shifting block is stretched out by this gap, realizes the unconfined rotational of the first gearshift shifting block and the second gearshift shifting block.
Adopt technique scheme, adopts an interlock board to hold two gearshift shifting blocks, make two shifting blocks when concrete gear selection operation; All have an effect with this interlock board, whole amount of parts is reduced, structure is compact more; And the accuracy and the flexibility of gearshift have been improved; Through cooperating of elbow and elongated slot, realized that the axial rotation of interlock board limits, make that the gear interlocking is reliable, the block selecting light and flexible.
