To realize gear selecting shift performance boost.
Background technology
Automotive engineering developed rapidly in recent years, and requirement of the people to commercial car maneuvering performance is higher and higher.With a large amount of
Using flexible shaft manipulation, gearbox operating mechanism becomes the important link for influencing vehicle maneuvering performance.And pervious gear selecting changes
Keep off heavy, feel is unintelligible, cannot meet the market demand.Therefore it is highly desirable to a kind of shift machine that can reduce shifting resistance
Structure.
Invention content
The utility model is to solve current commercial car speed changer there are shiftings heavy, the unsharp technical problem of feel,
A kind of gear selecting shift performance boost head cover is provided.
The utility model adopts the following technical scheme that realization：A kind of gear selecting shift performance boost head cover, head cover
Equipped with shift centering agency and block selecting positioning seat；It is described shift centering agency include be mounted on manipulate axle assembly on secter pat with
And shift positioning seat corresponding with secter pat；Secter pat one end opposite with shift positioning seat is in M type grooves；Shift positioning
By the connection of the first spring, there are one the shift positioning balls to match with the M type grooves of secter pat in seat；Block selecting positioning seat is pacified vertically
In hollow shift lever；The block selecting positioning seat is the hollow structure of upper end opening, and bottom is equipped with second spring, the
There are one block selecting positioning balls for the top connection of two springs.
For the head cover in neutral gear position, the shift steel ball in positioning seat of shifting gears locks the M on secter pat by axle assembly is manipulated
The bottom end of type groove, the idle stroke of gear-shifting rocker arm when reducing neutral gear, as shown in Figure 1.
After shift steel ball during putting into gear in shift positioning seat climbs to top from slot bottom, since shift positioning seat is hit by a bullet
Spring is sprung back, and can be generated a power-assisted for pushing shifting direction to by M slots shoulder on secter pat, be realized shift sucking.As shown in Figure 2.
Arrow direction is shifting direction, and generates equidirectional power assisted gearshift.
In terms of block selecting, former block selecting spacer pin is changed to block selecting positioning seat, sliding friction can be made to be changed to during block selecting
Steel ball rolling friction in block selecting positioning seat, keeps block selecting light, and keeps gear selecting structure simple.As shown in Figure 4.
Further, block selecting pivoted arm assembly is arranged at the position for being pierced by head cover there are one dust cover.
Block selecting pivoted arm assembly passes through double needle bearing support rotatings in the part inside head cover；Block selecting pivoted arm assembly exists
The position for being pierced by head cover is equipped with oil sealing.
The utility model cancels double O-ring sealing structures on former block selecting axis, using double needle bearings band oil sealing and dust cover
Structure effectively reduces friction, improves block selecting performance；Dustproof and waterproof effect can be played simultaneously, improve block selecting accuracy.Such as Fig. 3 institutes
Show.
The utility model at shift by increasing the important spare parts such as secter pat and shift positioning seat, it can be achieved that at neutral gear
The effect of sucking sense during reducing idle stroke and putting into gear；Needle bearing and block selecting positioning seat are used at block selecting, are improved simultaneously
The measures such as block selecting limit slot structure, make block selecting power reduce on control lever shaft, block selecting limit sense enhancing, and return is smooth.

Specific implementation mode
A kind of gear selecting shift performance boost head cover, head cover are equipped with shift centering agency and block selecting positioning seat 6；It is described to change
Gear centering agency includes being mounted on the secter pat 1 and shift positioning seat corresponding with secter pat 13 manipulated on axle assembly；Institute
It is in M type grooves to state the one end opposite with positioning seat 3 of shifting gears of secter pat 1；Shift gears positioning seat 3 in by the first spring 4 connection there are one
The shift positioning ball 5 to match with the M type grooves of secter pat 1；The block selecting positioning seat 6 is vertically installed in hollow shift lever 7；
The block selecting positioning seat 6 is the hollow structure of upper end opening, and bottom is equipped with second spring 8, the top connection of second spring 8
There are one block selecting positioning balls 9.
Block selecting pivoted arm assembly 14 is arranged at the position for being pierced by head cover there are one dust cover 12.
