Abstract
The utility model relates to a shifting-at-rotating-center meshing sleeve control mechanism. The shifting-at-rotating-center meshing sleeve control mechanism comprises a moving pull rod, a meshing sleeve, a right gear, a rotary main shaft, a left gear, an elastic pin, a set-forward base and steel balls; the left gear and the right gear are respectively fixedly mounted on an outer ring of the rotary main shaft through shaft housings; the meshing sleeve is connected with the set-forward base through the elastic pin; the set-forward base is mounted inside the rotary main shaft; and the set-forward base is connected with the moving pull rod through the steel balls mounted on the set-forward base. The moving pull rod is arranged in the middle of the rotary main shaft to control the meshing sleeve. According to the shifting-at-rotating-center meshing sleeve control mechanism, the pull rod is used in the middle of the center position of a shifting shaft, no external shifting fork and shifting rod are selected and used, and various gears and speeds can be conveniently, normally and reliably shifted in a limited space under the condition that gears are intensively arranged and distributed; the volume of a speed-shifting mechanism can be effectively reduced; and the layout of a speed-shifting system can be more compact, and the connection of the speed-shifting system can be more reliable.
Description
Technical field
The utility model relates to a kind of engagement cover operating mechanism in the rotating center gearshift, belongs to the mechanical transmissioning technology field.
Background technique
At present, the gearshift mode of known machine driven system gear is to adopt external loaded down with trivial details parts such as driving lever, shift fork and shifting block to stir the engagement cover, makes engagement cover and different gear engagement, thereby reaches the purpose of gearshift.Though this traditional engagement cover clutch mode is more reliable and more stable, it is big to take up room, and driving lever and shift fork very easily collide with other component and occur interfering.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Thereby a kind of engagement cover operating mechanism of rotating center gearshift is provided; This operating mechanism can solve traditional gear and take up room greatly, and driving lever and shift fork very easily collide with other component and the problem of interference occurs.
The technological scheme that provides according to the utility model; The engagement cover operating mechanism of rotating center gearshift comprises mobile pull bar, engagement cover, right gear, rotary main shaft, left gear, resilient key, sets base, steel ball ahead; Said left gear and right gear are fixedly mounted on the rotary main shaft outer ring through axle sleeve respectively; Engagement cover with set base ahead and be connected through resilient key, set base ahead and be installed on rotary main shaft inside, set base ahead and pass through steel ball mounted thereto and be connected with mobile pull bar.
Said mobile pull bar places rotary main shaft intermediate controlled engagement cover.
Compared with present technology the utility model has the following advantages:
The gearshift axle of the utility model is in the axle central position, and the middle pull bar that uses is not selected external shift fork, driving lever for use, under gear is arranged intensive situation, and can convenient, normal, reliable various gear of conversion and speed in limited space; Can effectively reduce the volume of gear; Make speed variator system arrange compact more, connect more reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise mobile pull bar 1, engagement cover 2, right gear 3, rotary main shaft 4, left gear 5, resilient key 6, set base 7 and steel ball 8 ahead.
Said left gear 5 is fixedly mounted on respectively on rotary main shaft 4 outer rings with right gear 3, and left gear 5 is that freely rotate at the center with right gear 3 with rotary main shaft 4; Engagement cover 2 with set base 7 ahead and link together through resilient key 6, engagement cover 2 moves through before and after spline is on rotary main shaft 4, and rotates together with rotary main shaft 4; Set base 7 ahead and be installed on rotary main shaft 4 inside, rotary main shaft 4, engagement are overlapped 2, are set base 7 sense of rotation and rotating speed unanimity ahead; Set base 7 ahead and be installed together, move pull bar 1 and place rotary main shaft 4 intermediate controlled engagement cover, will move pull bar 1 and move through steel ball between two holes mounted thereto 8 and mobile pull bar 1, then engagement cover 2, set base 7 ahead and follow mobile.
The mobile pull bar 1 that is in the rotating shaft center position through resilient key 6, set base 7 ahead, steel ball 8 drives in the engagement of rotary main shaft neutral position and spline engagement and overlaps 2; When engagement cover 2 moves to right with right gear 3 engagements, at this moment, right gear 3 and rotary main shaft 4 engagements, right gear 3 and rotary main shaft 4 work in the transmission system, at this moment, left gear 5 does not rotate or dallies; When engagement cover 2 moves to left, be separated from right gear 3 earlier, with left gear 5 engagements, in like manner, left gear 5 works with rotary main shaft 4 in the transmission system again, and at this moment, right gear 3 does not rotate or dallies.During engagement cover 2 move left and right, move pull bar 1 and reach under the very little external force effect and can not rotate with rotary main shaft in frictional force.Through placing rotary main shaft 4 middle mobile pull bar 1 control engagements to overlap, can carry out gear-change operation reliably., right gear and left gear can on rotary main shaft, realize the main axis rotation switching-over when being bevel gear.
The utility model can solve traditional gear and take up room greatly, and driving lever and shift fork very easily collide with other component and the problem of interference occurs.
