It is short, also result in put into gear it is not in place.Vehicle on the way travel if there is hang it is suddenly big or suddenly small not into shelves or gear angle, also can
The security risk of driving can be had by influencing shift-feel also.
Summary of the invention
For the transmission assembly assembled it is possible that shift angle do not meet technique require lead to shift-feel
It is not good enough or it is overproof seriously cause to shift gears not in place, make the position that cannot hang up on file, the present invention is exactly the shift angle required by technique
The gear of design one similar " logical to stop " detection detects locating piece, and by seeing whether contact, to judge to shift gears, whether angle meets
Technique requirement, guarantees the product quality of speed changer.
To achieve the goals above, the present invention is to realize by the following technical solutions：
A kind of transmission assembly shift angle measurement cubing of the invention, including telescopic base of the carrier head, school neutral position
Locating piece and 3/4 grade of detection angles locating piece；The school neutral position locating piece includes multiple positioning pins, the positioning of school neutral position
Block openings of sizes is straight pin diameter；3/4 grade of detection angles locating piece also includes multiple positioning pins, and 3/4 grade
Slot there are two being set on detection angles locating piece；The base of the carrier head for fix entire cubing transmission assembly shift gears bracket,
The base of the carrier head is equipped with the measurement end for judge shift angle, and the measurement end is controlled by fixing bolt elastic to be made to survey
It is flexible to measure end or so；When zero check, the school neutral position locating piece is mounted on the cubing groove center position of measurement end；Hang neutral gear
When, the opening of the school neutral position locating piece is inserted on the straight pin of transmission assembly rocker arm, and cubing zero-bit is by the fixation
Bolt is fixed；3/4 grade of detection angles locating piece is also mounted at cubing groove center position, hangs up gear in transmission assembly
When, if the straight pin of rocker arm touches the fluting end face of 3/4 grade of detection angles locating piece, illustrate that shift angle is super
Difference, if the straight pin of rocker arm illustrates angle qualification of shifting gears in 3/4 grade of detection angles locating piece fluting.
The openings of sizes of above-mentioned 3/4 grade of detection angles locating piece is exactly that the shift angle of transmission assembly drawing requirement is big
It is small.
Above-mentioned straight pin shift angle factory requires to be 17.5 ° ± 1.5 °.
Above-mentioned school neutral position locating piece opening diameter is 8 ± 0.02mm.
Above-mentioned straight pin diameter is 8mm.
The shift angle of above-mentioned rocker arm is 17.5 ° ± 1.5 °, and by triangle Pythagorean theorem, shift angle is converted into institute
State the big closed tolerance and position of 3/4 grade of detection angles locating piece or so, two slots.
The test method of above-mentioned cubing, including following steps：
(a) the telescopic base of the carrier head is fixed in transmission assembly shift bracket；
(b) the school neutral position locating piece is mounted on the cubing groove center position of measurement end, while school neutral position
The fluting position for setting locating piece is put into the straight pin of rocker arm, shakes transmission assembly by the measurement end for the base of the carrier head that stretches
Arm is in neutral gear and does not stress position, tightens the fixing bolt again at this time, the measurement end of the base of the carrier head is made to be in neutral position；
(c) the school neutral position locating piece is removed, while giving the power of transmission assembly to the left, hangs it into three gears；
(d) 3/4 grade of detection angles locating piece is installed in cubing groove center position；Judge whether straight pin can be with 3/4
Whether the left and right end of shelves detection angles locating piece left side fluting contacts, if touching 3/4 grade of detection angles locating piece, illustrates
Angle of shifting gears is overproof, if illustrating angle qualification of shifting gears within the fluting of the left side；
(e) step (c) and step (d) are repeated, put into gear hangs rocker arm into four gears to the right, and whether four gear shift angle of detection closes
Lattice.
The invention avoids directly measurement shift angles, and this measurement difficulty is big, and measurement inaccuracy passes through the requirement of angle
Size converts thinking, by seeing whether it can position with 3/4 grade of detection angles the location of after observation rocker arm straight pin shift
Block contact, the ingenious detection for being converted into logical only principle, so that speed changer factory high-effect high-quality be made to judge the shift angle of rocker arm
Correctness.It avoids because the security risk that the failures such as not in place of putting into gear cause, guarantees the quality of vehicle.
