Abstract
The utility model relates to a clutch bushing for motorcycle engine, in particular to a double clutch type primary clutch bushing. The utility model is characterized in that a keyway and at least two mounting holes used for installation of a spiral torsion spring are arranged on the bushing. The utility model has an advantage that: when the engine causes squeaking and noise, only the mounting holes installation position of the spiral torsion spring in the clutch bushing needs to be changed, thus the squeaking and noise of the engine are eliminated.
Description
Technical field
The utility model relates to a kind of clutch bushing of motorcycle engine, particularly two clutch type primary clutch linings.
Technical background
In two clutch type clutches of motorcycle engine, its primary clutch master gear end is equipped with a pinion and a lining, this pinion and master gear while and driving gear joggleword.Lining is fixed on the primary clutch with key, one helical torsional spring is housed in it, the two ends of this helical torsional spring are installed in respectively in the hanging hole of lining and pinion, give pinion one warping force, to control the back lash of itself and driving gear, thereby solve uttering long and high-pitched sounds that the gear engagement tension causes, mesh that pine causes from loud problem.But in fact in the finished product of producing, there is 30% motor still to occur uttering long and high-pitched sounds and leading approximately from the phenomenon of ringing.By adopting by NBS seven class precisions to the selected gear of the requirement of gear parameter, improve casing crankshaft hole and spindle hole centre distance positional accuracy, and the measures such as steel wire diameter of change helical torsional spring, still can not address this problem.
The model utility content
Technical problem to be solved in the utility model provides and a kind ofly through improved primary clutch lining it is installed on the clutch, with solve motor utter long and high-pitched sounds and from the problem of sound.
Described in the utility model pair of clutch type primary clutch lining offers keyway thereon and is used to install the hanging hole of helical torsional spring, and offer two helical torsional spring hanging holes on this primary clutch lining at least.
In actual production processing, can on the primary clutch lining, offer three helical torsional spring hanging holes, and the central angle that is formed centrally in two adjacent helical torsional spring hanging holes and the primary clutch lining is respectively 11 °～14 ° and 12 °～15 °.
In the concrete assembly process of clutch, can be earlier an end of helical torsional spring be installed in the hanging hole of the original position of primary clutch lining, if the motor generation is uttered long and high-pitched sounds or from sound, the end with helical torsional spring when reprocessing is retrofitted in one of them hanging hole of two other hanging hole.
Described in the utility model pair of clutch type primary clutch lining is owing to offered three hanging holes thereon, and two newly-increased hanging holes are positioned at the adjacent both sides of former hanging hole, because of former hanging hole position reasonable substantially, most of motor (having 70% approximately) can not produce utters long and high-pitched sounds from sound, so utter long and high-pitched sounds or from the motor that rings for generation, only need to change the hanging hole mounting point of helical torsional spring in clutch bushing, just can change helical torsional spring a little and affact torque magnitude on the clutch pinion, with the back lash between adjusting gear, thus eliminate motor utter long and high-pitched sounds and from ringing phenomenon.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the plan view of described in the utility model pair of clutch type primary clutch lining;
Fig. 2 is the A-A cross section view of lining among Fig. 1;
Fig. 3 is primary clutch shell combination schematic representation.
In Fig. 1, Fig. 3, the component of each piece mark representative are respectively: 1-lining, 2-helical torsional spring, 3-hanging hole.
Embodiment
As shown in Figure 1 to Figure 3, offer a keyway and three hanging holes 3 that are used to install helical torsional spring 2 on this pair clutch type primary clutch lining, and the central angle that is formed centrally in two adjacent helical torsional spring hanging holes and the primary clutch lining be respectively 12 ° 20 ' and 13 ° 40 '.In the concrete assembly process of clutch, can be earlier an end of helical torsional spring 2 be installed in the hanging hole 3 of primary clutch lining 1 original position (hanging hole in the middle of among Fig. 1), if the motor generation is uttered long and high-pitched sounds or from sound, the end with helical torsional spring when reprocessing is retrofitted in one of them hanging hole of two other hanging hole.
