Abstract
The utility model belongs to the technical field of automotive transmissions, and relates to a gear locking mechanism for an automotive transmission. The gear locking mechanism comprises a gear shift shell, wherein a gear shift shaft is arranged in the gear shift shell; a double-H valve is mounted outside the gear shift shell; a gear shift head and a gear locking ring are fixedly mounted on the gear shift shaft; the gear shaft shell is provided with a locking pin matched with the gear locking ring for use; and an interlocking fork is arranged on the gear shift shaft in a sleeving manner. The gear locking mechanism has the benefits that the gear shift direction is controlled by regulating the relative position of the locking pin and the gear locking ring, so that different gears are locked and the gear shift of the auxiliary case is achieved by driving the double-H valve through the interlocking fork. Besides, the gear locking mechanism is reliable in design principle, simple in structure, and reliable in performance, realizes pure mechanical locking and has a wide application prospect.
Description
Technical field
The utility model belongs to automotive transmission technical field, relates to a kind of automotive transmission, relates in particular to a kind of automotive transmission shift-lock locking mechanism.
Background technique
Automotive transmission is a set of for coordinating the speed change gear of the rotating speed of motor and the actual travel speed of wheel, for bringing into play the optimum performance of motor.Speed changer can, in vehicle traveling process, produce different gear ratio between motor and wheel, by gearshift, can make engine operation under its best power performance state.
The speed changer of heavy-duty car and some automobile coupling is the many gear speed transmissions with odd-side, if the control of speed changer adopts two H manipulation types, need in design to realize odd-side when high gear and low gear, the gear of main tank is different, this just need to work as odd-side need to carry out locking some gear of main tank when high gear, and other some gear of main tank need to be carried out to locking during in low gear when odd-side.
Model utility content
The purpose of this utility model is, the defect existing for above-mentioned prior art provides design a kind of automotive transmission shift-lock locking mechanism.
For achieving the above object, provide following technological scheme:
A kind of automotive transmission shift-lock locking mechanism, comprising: gearshift housing, in described gearshift housing, be provided with shifting shaft, and described gearshift housing is provided with double H valve and fitting seat; It is characterized in that: on described shifting shaft, be installed with gearshift head and shift-lock stop ring, be provided with the lock pin being used in conjunction with shift-lock stop ring in described fitting seat, on described shifting shaft, cover has interlock fork.
Preferably, described interlock fork is located at a gearshift both sides.
Preferably, described lock pin is the cylinder with hemisphere plush copper.
The beneficial effects of the utility model are, control the restriction of gearshift direction by adjusting the relative position of lock pin and shift-lock stop ring, thereby realize the locking of different gears, and drive double H valve to realize the gearshift of odd-side by interlock fork; In addition, the utility model design principle is reliable, simple in structure, pure mechanical locking, and reliable performance, has application prospect very widely.
Accompanying drawing explanation
A kind of automotive transmission shift-lock locking mechanism embodiment's that Fig. 1 provides for the utility model structural representation.
Wherein, the 1-housing of shifting gears, 2-interlock fork, the 3-head of shifting gears, 4-shifting shaft, 5-shift-lock stop ring, 6-gear-shifting rocker arm, 7-lock pin, 8-double H valve, 11-fitting seat.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is elaborated, and following examples are to explanation of the present utility model, and the utility model is not limited to following examples.
Fig. 1 shows a kind of automotive transmission shift-lock locking mechanism that the utility model provides, comprise: gearshift housing 1, in described gearshift housing 1, be provided with shifting shaft 4, described gearshift housing 1 is provided with double H valve 8 and fitting seat 11, on described shifting shaft 4, be installed with gearshift 3 and shift-lock stop ring 5, described gearshift housing 1 is provided with fitting seat 11, lock pin 7 is installed in fitting seat 11, described lock pin 7 is used in conjunction with shift-lock stop ring 5, in order to limit the sense of rotation of shift-lock stop ring 5, on described shifting shaft 4, cover has interlock fork 2, described interlock fork 2 is connected to the both sides of gearshift 3, shifting shaft 4 is connected with gear-shifting rocker arm 6, by gear-shifting rocker arm 6, realize moving axially and rotating of shifting shaft 4.
In the present embodiment, interlock fork 2 can, with axially the moving of shifting shaft 4, can drive double H valve 8 to realize the gearshift of odd-side by the movement of interlock fork 2.
In the present embodiment, lock pin 7 is the cylinder with hemisphere plush copper.
In the present embodiment, gearshift 3 and shift-lock stop ring 5 can move axially and rotate with shifting shaft 4, the sense of rotation of shift-lock stop ring 5 limits by lock pin 7, adjust as required the relative position of lock pin 7 and shift-lock stop ring 5, thereby limit the sense of rotation of shift-lock stop ring 5, thereby realize the locking of different gears.
Disclosed is above only preferred implementation of the present utility model; but the utility model is not limited thereto; any those skilled in the art is thinkable does not have creationary variation; and not departing from some improvements and modifications of doing under the utility model principle prerequisite, all should drop in protection domain of the present utility model.
