Miscellaneous, arrangement is difficult, and space-consuming is big；Flexible axle connection transmission efficiency is low, and it is poor to manipulate feel.It is preposition to adapt to speed changer
Long head Medium Truck design requirement, meets the requirement of shift of transmission performance and operation comfort, it is also very desirable to which one kind takes empty
Between small, transmission efficiency and the good speed changer of manipulation hand lever.
The content of the invention
Arrangement be present to solve two kinds of kinds of drive used in medium-sized normal control vehicle speed changer at present in the utility model
A kind of difficult and low transmission efficiency technical problem, there is provided special direct control transmission of normal control vehicle.
The utility model adopts the following technical scheme that realization：A kind of special direct control transmission of normal control vehicle, including
The operating mechanism being arranged on DC6J65T series of transmission top covers；The operating mechanism include through gear-box top cover and on
Build the gear level set；Gear level lower end shifting block is placed in neutral gear position in transmission upper cover guide block groove, and shifting block top is adopted with top cover
By the use of spherical connection and fulcrum is acted as gear level, the gear-box top cover side position relative with spherical junction is provided with hole, hole
The alignment pin of the free degree of built-in restricted gear level；Gear level is arranged with spring in the part below spherical connection.
The operation principle of utility model：
Speed changer main tank part is normally connected with engine and power transmission shaft, and actuating element structure is as shown in Fig. 2 under gear level
End shifting block is placed in neutral gear position in transmission upper cover guide block groove.Shifting block top uses spherical connection with top cover, is moved as gear level
Make fulcrum.Top cover lateral opening hole, install alignment pin additional, limit the free degree of gear level rotation.Realized and changed using coiled spiral spring
During pin is fixed and return function.It can be transferred by space in certain limit according to arrangement demand, meet to drive on gear level top
Sail room control stick position requirement.
The speed changer main tank part is normally connected with engine and power transmission shaft, and actuating element gear level will according to arrangement
Ask, through driver's cabin bottom surface, transferred by space in certain limit, be arranged into the position beneficial to driver's operation.In gear level
After upper installation handle ball, driver directly can operate to gear level, realize choosing, gear shift function（As shown in Figure 1）.Manipulate knot
Structure is not required to stiff rod or flexible axle connection, is not required to vehicle configuration executor, improves the transmission efficiency of speed changer operation, make choosing, gear shift
Operating handle clear and definite, and because lever ratio is big, choosing, berth-changing strength are small, and gearshift is light, improves handling comfort.
The utility model can be matched with the light-duty long special DC6J65T direct control transmissions of head truck in 7 ~ 12 meters, meet
500 ~ 750Nm of engine max. output torque, the fast ratio 5.56 ~ 6.72 of a gear, overgear speed ratio 0.74 ~ 0.81 or so.Using length
Bar directly manipulates, and improves the manipulation feel and comfortableness of vehicle, meet it is high-end in light-duty normal control vehicle frequently put into gear, manipulate it is comfortable
Requirement.
The special stock direct control transmission feature of normal control vehicle described in the utility model：
A. block selecting is accurate, puts into gear light；
B. operating mechanism is using directly manipulation, transmission efficiency；
C. it is adapted to medium-sized normal control vehicle arrangement demand.
