Description
Technical field
The invention belongs to automotive transmission field, and in particular to a kind of manual transmission interlocking cage and speed changer.
Background technology
Interlocking cage is used primarily in gear shift mechanism of manual transmission, position master of the interlocking cage in gear shift mechanism
If being enclosed on the outside of gear shifting pulling head, and it is enclosed on shifting shaft, and can be together being shifted gears with gear shifting pulling head together with gear shifting pulling head
Moved axially on axle.Gear shifting pulling head connects with shifting shaft spline and can be with being rotated together with shifting shaft, and interlocking cage then changing by empty set
On gear shaft, at the same time, interlocking cage top portion prevents from interlocking the front and rear pendulum of cage in the stopper slot of aluminum gear shift mechanism housing
It is dynamic.
Interlocking cage main function be when speed changer carry out shifting operation when, block selecting shifting block rotating band move gear shifting pulling head and
Interlocking cage moves axially on shifting shaft, while gear shifting pulling head moves axially in fork slot and realizes block selecting, shifting shaft rotating band
Dynamic gear shifting pulling head swing in fork slot, gearshift is realized so as to promote shift fork to put into gear forward or put into gear backward.Now due to
Cage top portion is interlocked in the stopper slot of aluminum gear shift mechanism housing so that interlocking cage remains vertical state, will not be with changing
Keep off the rotation of shifting block and shifting shaft and swing.The interlocking block for interlocking cage bottom portion is embedded in fork slot, is also allowed for except changing
The fork slot of gear can be moved forward and backward where gear shifting block, and the fork slot of other gears is protected due to interlocking the presence of cage interlocking block
Hold and can not arbitrarily be trip stopped in neutral gear position, prevent from hanging up two gears simultaneously, so as to realize interlock function.
It is interlocking basket structure of the prior art as shown in Figure 1.Fig. 2 show existing interlocking basket structure in hand gear
Operating position in device gear shift mechanism.
Prior art interlocks basket structure, and common in use there are the following problems：
The operation of manual transmission shifting is controlled by driver, and its shifting operating physical force is not of uniform size, when gear shift operation power is larger
When, shifting shaft is rotated, drives gear shifting pulling head rotation, gearshift stroke is then spacing by interlocking the progress of the rib on cage, prevents from shifting gears
It is excessive that speed changer part is caused to damage.Interlocked because long-time acts on power on cage so that interlocking cage top portion is to shifting
The long-term strong effect of the stopper slot of mechanism shell.
Gear shift mechanism housing is aluminium casing, and lower hardness, long-term stress, which acts on, causes stopper slot and interlocking cage gap
It is increasing（Certain interval be present due to processing dimension reason in the stopper slot of interlocking cage itself and gear shift mechanism housing）, it is additional
Gear shifting pulling head is applied to the effect of the power of interlocking cage rib so that interlocking cage is into certain oblique angle, when oblique angle reaches certain angle
Afterwards, while gear shifting pulling head hangs up forward or backward a gear, the interlocking block in interlocking cage bottom portion also withstands forward or backward it
The fork slot of his gear causes fork slot to move forward or backward, and the gearshift tooth for causing other gears is cased with forward by such a form
Or trend of putting into gear backward so that contact and rub between synchronous ring and conjunction gear, greatly damage speed changer part.
When carrying out operation out of supply, due to other gear synchronization rings and the absorption affinity with reference to caused by tooth contact friction so that
Current shift off-gear power increases, and shifting comfortableness declines.
In addition, in order to process the stopper slot in gear-selecting-shifting mechanism housing, the work of one of groove milling need to be increased after casting
Sequence.And the groove needs to ensure there is good machining accuracy, and higher intensity and hardness could be realized before preventing from interlocking cage
The function of swinging afterwards.But general automotive transmission is in order to mitigate the housing of weight generally use aluminum, and aluminium casing is that do not have
These standby characteristics.In this case, using stopper slot and the spacing mode of interlocking cage body fits wastes time and energy and effect
It is bad.
Therefore, in view of existing interlocking cage spacing inaccuracy in manual transmission aluminum gear shift mechanism housing, makes for a long time
With causing aluminum gear shift mechanism housing stopper slot to wear, cause to interlock cage in fork slot swing, decline interlocking effect
This problem, and the risk that damage derailleur body and shifting comfortableness decline be present, it is necessary to existing interlocking cage is carried out
Research and innovation is improved.
