Embodiment 1

[0023] see figure 1 and figure 2 , figure 1 It is a simple diagram of the control structure of a common gearbox, figure 2 It is a partial sketch of the operating mechanism of the present invention, and the biggest difference between the two is that a cylinder-piston actuator 4 is added to the original gearbox operating device. When the air pipe 3 and the cylinder have air, the air pressure overcomes the spring force, the piston 5 stretches out, and there is a corresponding groove on the shift shaft 6, both function to limit the rotation of the shift shaft 6; when the cylinder has no air At this time, the piston rod automatically returns under the action of the spring, releasing the restriction on the shift shaft.

[0024] For the gas connection of the whole system, see image 3 or Figure 4 . At cab clutch pedal 8 ( image 3 ) or booster pump 9 ( Figure 4 ) add an on-off air valve 2 as the control air valve, the air source of the air valve is connected to the air fi...

Embodiment 2

[0031] Example 2 is "ventilation unlock":

[0032] Such as Figure 5 As shown, when the piston 5 has no gas in the air pipe 3, due to the promotion of the spring force, the piston 5 interacts with the shift shaft 6 grooves, the shift shaft can not rotate, and the driver can not be in gear. When trachea and cylinder had gas, piston 5 customer service spring force under gas pressure effect is backed away from shift shaft one side, removes the locking of shift shaft 6, shift shaft 6 can rotate, and the driver can shift gears.

Abstract

The invention discloses a transmission main box lock stop protection mechanism. The transmission main box lock stop protection mechanism comprises a cylinder piston actuation mechanism mounted on a transmission control device, wherein the cylinder piston actuation mechanism is communicated with an air filter or a whole vehicle air source through connecting or disconnecting an air valve; when a clutch is not separated, the cylinder piston actuation mechanism can limit the rotation of a gear shifting shaft; and when the clutch is separated, the cylinder piston actuation mechanism relieves the limit to the gear shifting shaft. The transmission main box lock stop protection mechanism adopts a mechanical-pneumatic mechanism; all pneumatic elements are mechanical; no electric or electronic element is adopted; the mechanical structure resists high or low temperature, is not interfered by electromagnetism, resists moisture and dust, and is suitable for various server working conditions; and all elements adopted by the transmission main box lock stop protection mechanism are simple in structures; and for mechanical parts, the structure is simpler, and the reliability is higher.

Description

【Technical field】 [0001] The invention belongs to the technical field of transmissions, and relates to a lock protection mechanism, in particular to a transmission main box lock protection mechanism. 【Background technique】 [0002] With a manual transmission, the driver must depress the clutch when engaging a gear. However, in actual use, a large amount of professional drivers, such as bus drivers and large truck drivers, do not step on the clutch during gear shifting. Long-term operation in this way will cause great damage to the internal parts of the gearbox, especially the synchronizer, and greatly shorten the life of the synchronizer. What's more, the synchronizer will be damaged instantly. [0003] The present invention designs a pneumatic mechanical gear locking device. If the clutch is not disengaged, the mechanism will limit the rotation of the gear shift lever and prevent the driver from shifting gears, thus reminding the driver to step on the clutch when shifting ...
