Add block selecting detent mechanism, improve block selecting feel, speed-changer operation performance can be significantly improved.
The content of the invention
The purpose of this utility model is to provide a kind of speed changer block selecting detent mechanism that it is unclear to solve existing block selecting feel
Clear, clamping stagnation of putting into gear caused by block selecting is not in place is largely present, the defects of causing the very big complaint of user.
In order to achieve the above object, the technical solution adopted in the utility model is specific as follows：
A kind of speed changer block selecting detent mechanism provided by the utility model, including manipulation device assembly, horizontal gear level, choosing
Control block and the spacing pin of block selecting are kept off, wherein, block selecting control block is sleeved on horizontal gear level, and the spacing pin of block selecting is arranged on behaviour
On vertical assembly of devices, and block selecting control block is engaged with the spacing pin of block selecting.
Preferably, the working end of the block selecting control block is the block selecting area of gear, and the block selecting area is tooth type structures, described
Tooth type structures keep off four, area teeth groove including area of reversing gear, one/bis- gear area, three/tetra- gear Qu Hewu/six.
Preferably, ramp angles of the tooth type structures in four Ge Dang areas in block selecting direction are 37 °, block selecting return direction it is oblique
Angle of slope is 20 °.
Preferably, reverse gear area tooth type structures block selecting direction ramp angles be 53 °, and its slope drop than other gear
The high 0.79mm in position.
Preferably, the working end of the spacing pin of the block selecting is spherical structure, and the spherical structure is engaged with teeth groove.
Compared with prior art, the beneficial effects of the utility model are：
A kind of speed changer block selecting detent mechanism provided by the utility model, by installing a block selecting on horizontal gear level
Control block, a spacing pin of block selecting is installed on manipulation device assembly, by block selecting control block and block selecting limited post pin bank into
One block selecting detent mechanism, it is intended to provide block selecting positioning for speed changer, increase block selecting feel, ensure block selecting in place.Integrate simultaneously
Reverse gear lock, improves choosing and reverses gear feel.
Further, block selecting feel is produced by compression of the spring to the spacing pin of block selecting and release.
Further, the ramp angles in block selecting direction are arranged to 37 °, the ramp angles in block selecting return direction are arranged to
20 °, be that guarantee block selecting operation can free return in order that block selecting return resistance is smaller.
Further, ramp angles of the area in block selecting direction that will reverse gear are arranged to 53 °, and its slope drop is than other gears
High 0.79mm, purpose make choosing reverse gear the bigger power of needs, there is provided choosing is reversed gear feel, ensure that the lock function that reverses gear.
Brief description of the drawings
Fig. 1 is block selecting detent mechanism structural representation；
Fig. 2 is block selecting control block structural representation；
Wherein, 1, manipulation device assembly 2, horizontal gear level 3, block selecting control block 4, the spacing pin of block selecting.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
As shown in figure 1, a kind of speed changer block selecting detent mechanism provided by the utility model, including manipulation device assembly 1, horizontal stroke
To gear level 2, block selecting control block 3 and the spacing pin 4 of block selecting, wherein, block selecting control block 3 is sleeved on horizontal gear level 2, block selecting
Spacing pin 4 is arranged on manipulation device assembly 1, and the pin 4 spacing with block selecting of block selecting control block 3 is engaged.
As shown in Fig. 2 the working end of the block selecting control block 3 is the block selecting area of gear, the block selecting area is tooth type structures,
The tooth type structures include four teeth groove, area of respectively reversing gear, one/bis- gear area, three/tetra- gear areas, five/six gear areas, wherein three/tetra-
Gear area is neutral area.
When carrying out block selecting operation, one/bis- gear area, three/tetra- gear Qu Hewu/six keep off the tooth type structures in area in block selecting direction
Ramp angles are 37 °, and the ramp angles in block selecting return direction are 20 °, and this is in order that block selecting return resistance is smaller, ensures block selecting
Operation can free return；
Wherein, the ramp angles of the tooth type structures in block selecting direction in area of reversing gear are 53 °, and its slope drop is than other gears
High 0.79mm, choosing is so set to reverse gear the bigger power of needs, there is provided choosing is reversed gear feel, ensure that the lock function that reverses gear.
The working end of the spacing pin 4 of block selecting is spherical structure, and the spherical structure is engaged with teeth groove.
At work：
When manipulation device carries out block selecting operation, horizontal gear level 2 drives block selecting control block 3 to move in the lateral direction,
Now block selecting control block 3 and the spacing pin 4 of block selecting produce relative movement；It is spacing by block selecting during block selecting 3 transverse shifting of control block
Compression of the spring set between pin 4 and manipulation device assembly 1 to the spacing pin of block selecting 4 and release produce block selecting feel.
During neutral, the spacing pin 4 of block selecting is withstood in 3/4 gear teeth groove, when manipulating the gear block selecting of progress 1/2, block selecting control block 3
Moved right together with horizontal gear level 2, now need to overcome the spring force of the spacing pin 4 of block selecting, now block selecting power is larger.When
After block selecting control block crosses the convex top between 1/2 gear block selecting area and 3/4 gear block selecting area, block selecting power reduces rapidly, block selecting limited post
Pin 4 is fallen into the teeth groove in 1/2 gear block selecting area, and a kind of " falling hole sense " is had at driver's handball, can allow the subjective sensation of driver
Block selecting in place, can now be completed to put into gear.
When choosing is reversed gear, block selecting positioning pin 4 is arrived first in the teeth groove in 1/2 gear block selecting area, and now block selecting control block 3 continues
Move right, due to selecting the limit convex top gradient reversed gear bigger, drop is higher, so choosing, which is reversed gear, needs bigger power, this is just real
The function for the lock that reverses gear is showed.
A kind of speed changer block selecting detent mechanism, proposes the concept of block selecting feel first, and then is embodied as gearbox increase
Block selecting feel, make block selecting positioning apparent, put into gear more smooth；It is integrated with the lock function that reverses gear simultaneously.With obvious advanced and
It is innovative.
