Embodiment Construction
[0033] like figure 1 and figure 2 As shown, a 6MT reverse gear locking mechanism, the reverse gear locking mechanism is located in the space enclosed by the interlock plate 9 as a whole, and the reverse gear locking mechanism includes:
[0034] The ratchet wheel 11 is installed on the selector shaft 1 .
[0035] The pawl 13 can be engaged with or disengaged from the ratchet 11 when necessary. like figure 2 and image 3 As shown, the pawl 13 is installed on the 3 / 4 fork bracket 5;
[0036] When shift finger 3 is in 4th gear, shift finger 3 will be as Figure 4 As shown, the ratchet wheel 11 is pushed to rotate, and the ratchet wheel 11 blocks the gear selection limit pin 12, so that the shift finger 3 cannot continue to move to the reverse gear selection position when it is in the 5 / 6 gear selection position. This not only realizes the reverse gear locking function, but also has the 5 / 6 gear selection and positioning function.
[0037] Figure 4 It is a schematic diag...

The invention provides a 6MT reverse gear latching mechanism. The whole 6MT reverse gear latching mechanism is located in a speed changer. The reverse gear latching mechanism comprises a ratchet wheel and a pawl, the ratchet wheel is installed on a gear shifting shaft, the pawl can be occluded with the ratchet wheel, and the pawl is mounted on a 3 / 4 gear fork frame. When a gear shifting finger puts into a fourth gear, the gear shifting finger drives the ratchet wheel to rotate, the ratchet wheel blocks a gear shifting limiting pin, and thereby, the gear shifting finger can not further move to a gear shifting position of a reverse gear when located at a gear shifting position of a 5 / 6 gear. According to the 6MT reverse gear latching mechanism, the whole 6MT reverse gear latching mechanism is located in space defined by interlocking plates, and thereby, defects that gear shifting comforts are affected when traditional reverse gear latching mechanisms are designed on gear shifters are overcome; besides, the whole structure is simple and compact; when the gear shifting finger puts into the fourth gear, the gear shifting finger drives the ratchet wheel to rotate, the ratchet wheel blocks the gear shifting limiting pin, and thereby, the gear shifting finger can not further move to the gear shifting position of the reverse gear when located at the gear shifting position of the 5 / 6 gear; accordingly, a reverse gear latching function can be achieved, and 5 / 6 gear shifting and locating functions can be achieved. The invention further provides a 6MT speed changer.
Description
technical field [0001] The invention relates to a reverse gear locking mechanism, in particular to a 6MT (6 manual forward gears not including reverse gear) reverse gear locking mechanism and a 6MT transmission. Background technique [0002] In order to make the driving wheels of the car output the torque and speed suitable for the working conditions, it is necessary to shift gears. The gears of the car are divided into two types: forward gear and reverse gear. The gear speeds of these two gears are opposite. If the reverse gear is accidentally engaged when the forward gear is engaged, it is easy to damage the accessories of the transmission and the engine, and even cause traffic accidents. At present, there is a reverse gear locking mechanism on the market, the function of which is to prevent the reverse gear from being accidentally engaged when the forward gear is engaged. In traditional transmissions, the reverse gear locking mechanism is usually designed on the shifter,...
