Abstract
The utility model relates to a gear shifting protection device. The gear shifting protection device comprises an end cover, a sensor driving ring, a gear shifting shaft, a shell and a locking pin, wherein the sensor driving ring is arranged in the end cover, the gear shifting shaft is arranged inside the sensor driving ring, the gear shifting shaft and the sensor driving ring are fixed into a whole through an elastic cylindrical pin, the shell is fixed to one side of the end cover through bolts, and the locking pin is inserted into the shell in a sliding mode and is of a T shape. A spring is arranged at the rear end of the locking pin. A pin hole matched with one end of the locking pin in outer diameter is formed in the end cover. The head end of the locking pin is inserted into the pin hole under the action of the spring. An air inlet channel is arranged on the shell. An opening of the air inlet channel inside the shell is located in the inner side of the locking pin. The air inlet channel is connected to a whole vehicle air source by means of a clutch system through an air tube. When a user treads down a clutch pedal, a clutch is completed separated, then, compressed air enters the shell through the air inlet channel and pushes the locking pin to move to compress the spring, at the moment, the locking pin is disengaged from the pin hole in the sensor driving ring, a driver pulls a gear shifting handle at the moment, and therefore gear shifting work can be completed.
Description
Technical field
The utility model relates to heavy duty automobile gear box technical field, is specifically related to a kind of gearbox shifting protective gear.
Background technique
In car load running process, driver has operation lack of standardization sometimes, and not stepping on clutch pedal, directly shifts gears.Though this operation can be forced to shift gears, and has following shortcoming: because clutch does not have separation, cause speed changer additionally to increase the wearing and tearing of gear in shift process, use its life-span thereby reduce; In shift process, the impact of car load is increased, and with unnecessary gear tooth noise, car load shifting comfort is weakened; Gear shifting force increases, if often carry out not stepping on clutch pedal, directly shifts gears, and driver more easily produces tired, has reduced driving safety coefficient.
Summary of the invention
The utility model is in order to overcome the deficiency of above technology, thereby providing a kind of driver's of preventing not stepping on clutch pedal to shift gears protects gearbox, improve the gearbox gearshift protective gear in working life.
The utility model overcomes the technological scheme that its technical problem adopts:
This gearshift protective gear, comprise end cap, be arranged at the sensor driving ring in end cap, be installed on shifting shaft sensor driving ring inside and be fixed on one by elastic cylindrical pin and sensor driving ring, be secured by bolts in the housing of end cap one side, slip is plugged in the T-shaped lock pin in housing, described lock pin rear end is provided with spring, on described end cap, be provided with the pin-and-hole matching with lock pin head end outside dimension, under the effect of spring, the head end of lock pin is plugged in pin-and-hole, on described housing, be provided with intake duct, the opening of the intake duct of described enclosure interior is positioned at lock pin inner side, described intake duct is connected in car load source of the gas by tracheae through clutch system.
Can manual shift in order to realize when the emergency situations still, above-mentioned pin-and-hole is cone shape hole, the tapering that the head end of described lock pin is taper type and its tapering and cone shape hole matches.
In order to realize better sealing, also to comprise, be installed on be slidably matched seal ring I on face and be installed on lock pin and seal ring II that end cap is slidably matched on face of lock pin and housing.
The beneficial effects of the utility model are: when let slip the clutch, by pressurized air clutch system, work, after the complete separation of clutch, car load source of the gas is delivered to intake duct through clutch system by tracheae, pressurized air enters in housing by intake duct, promote that lock pin moves and Compress Spring, now lock pin departs from from the pin-and-hole of sensor driving ring, thereby now driver pulls shift handle and can drive shifting shaft band dynamic sensor driving ring to rotate the gearshift work that completes.When driver does not pay attention to clutch pedal and directly pulls shift handle when gearshift, car load source of the gas cannot enter in housing through clutch system, and now lock pin is plugged in pin-and-hole under the elastic force of spring, so driver cannot complete gearshift work.Thereby reduced, do not step on the impact that clutch shifting causes, improved the working life of gearbox.

In figure, 1. housing 2. spring 3. lock pin 4. intake duct 5. seal ring I 6. seal ring II 7. end cap 8. sensor driving ring 9. elastic cylindrical pin 10. shifting shaft 11. tracheaes.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
This gearshift protective gear, comprise end cap 7, be arranged at the sensor driving ring 8 in end cap 7, be installed on shifting shaft 10 sensor driving ring 8 inside and be fixed on one by elastic cylindrical pin 9 and sensor driving ring 8, be secured by bolts in the housing 1 of end cap 7 one sides, slip is plugged in the T-shaped lock pin 3 in housing 1, described lock pin 3 rear ends are provided with spring 2, on described end cap 7, be provided with the pin-and-hole matching with lock pin 3 head end outside dimensions, under the effect of spring 2, the head end of lock pin 3 is plugged in pin-and-hole, on described housing 1, be provided with intake duct 4, the opening of the intake duct 4 of described housing 1 inside is positioned at lock pin 3 inner sides, described intake duct 4 is connected in car load source of the gas by tracheae 11 through clutch system.When let slip the clutch, by pressurized air clutch system, work, after the complete separation of clutch, car load source of the gas is delivered to intake duct 4 through clutch system by tracheae 11, pressurized air enters in housing 1 by intake duct 4, promote that lock pin 3 moves and Compress Spring 2, now lock pin 3 departs from from the pin-and-hole of sensor driving ring, thereby now driver pulls shift handle and can drive shifting shaft 10 band dynamic sensor driving rings 8 to rotate the gearshift work that completes.When driver does not pay attention to clutch pedal and directly pulls shift handle when gearshift, car load source of the gas cannot enter in housing 1 through clutch system, and now lock pin 3 is plugged in pin-and-hole under the elastic force of spring 2, so driver cannot complete gearshift work.Thereby reduced, do not step on the impact that clutch shifting causes, improved the working life of gearbox.
Above-mentioned pin-and-hole is cone shape hole, and the tapering that the head end of described lock pin 3 is taper type and its tapering and cone shape hole matches.Adopt the lock pin 3 of cone structure and the taper hole of cone structure, lock pin 3 with respect to cylindrical structural, during emergency situations in car load running process, by increase gear shifting force on shift handle, can occur when abnormal at car load bleed pressure, be that ramp structure can make sensor driving ring 8 detach from lock pin 3 by lock pin 3 with the surface of contact of taper hole.Improved reliability.If so now driver can not easily shift gears, but because lock pin 3 and sensor driving ring 8 is directly not locked, therefore in the situation that increasing external force, still can force gearshift, the generation of the dangerous situation causing to prevent from can not shifting gears in emergency case.
Also comprise and be installed on be slidably matched seal ring I 5 on face and be installed on the seal ring II 6 that lock pin 3 and end cap 7 are slidably matched on face of lock pin 3 and housing 1.At the increase seal ring that is slidably matched out, can improve tightness, prevent that the situation of gas leakage from occurring, improved the reliability of using.
