Abstract
The utility model belongs to the sort of automobile speed changers and particularly relates to a speed changer with bidirectional torsion damper gear pairs. The speed changer is composed of multiple gear pairs and is characterized in that an input shaft is normally meshed with a middle shaft normally meshed gear. A bidirectional torsion damping part is additionally arranged on the middle shaft normally meshed gear to eliminate a side gap between the an input shaft gear and the middle shaft normally meshed gear and avoid that idling and abnormal sounding occur to the speed changer as an engine outputs unstably and causes impact of tooth faces. The bidirectional torsion damping part is a concentric damping disc. A fixed columnar pin is arranged on the middle shaft normally meshed gear and the damping disc abuts against the columnar pin through a torsion spring. The speed changer with the bidirectional torsion damper gear pairs is strong in generality, compact and reasonable in structure and low in cost.
Description
Technical field
The utility model belongs to the automotive transmission class, specifically is a kind of speed changer with bidirectional torsion vibration damper gear pair.
Background technique
Present domestic most of commercial car is generally four-stroke ic engine, and four-stroke ic engine will cause torsional vibration because of itself periodic motion, add the sequentially fired of casing top half, has brought the irreqularity of bent axle to rotate.And the feature natural frequency that power transmission system had, can be converted into the irregular rotation that motor produces the torsional vibration transmission again and give speed changer, and speed changer is because of its reasons in structure, must be gapped during gear engagement, irregular input has caused the not steady of gear engagement, caused the idling abnormal sound problem of speed changer, have a strong impact on the performance of speed changer, the improvement project of present most of auto vendor is implemented secondary damping scheme for increasing double mass flywheel, this scheme effect is obvious, but because of the higher existing market popularity rate of actual cost not high.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, a kind of compactness as a result, reliable performance is provided, avoids steadily not caused by motor output the band bidirectional torsion vibration damper gear pair speed changer of idling noise by increasing the bidirectional torsion damping device.
The utility model is achieved through the following technical solutions:
A kind of speed changer of the utility model with bidirectional torsion vibration damper gear pair, speed changer is made up of gear pair some, it is characterized by: input shaft and jack shaft constant mesh gear are normal engagement, on the jack shaft constant mesh gear, increase the bidirectional torsion vibration damper, to eliminate the sideshake between input shaft gear and the jack shaft constant mesh gear, eliminate the speed changer idling abnormal sound that does not steadily cause flank of tooth impulsive sound to be caused because of motor output.
Bidirectional torsion vibration damper of the present utility model is a concentric damping disc, damping disc itself has certain inertia, fixing straight pin is arranged on the jack shaft constant mesh gear, damping disc withstands straight pin by torsion spring, when unsettled rotation appearred in gear transmission, damping disc will promote spring because of self inertia, spring promotes gear, forces the stable gear transmission.
When the utility model is worked at speed changer, owing on the speed changer constant mesh gear, increase the bidirectional torsion damping device, in the gear operation process, pass through the gap between the bidirectional torsion damping device elimination gear, guarantee when the motor output speed is not steady, fully buffering reaches the purpose of eliminating the idling noise.The utility model highly versatile, compact structure is reasonable, and cost is low.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Fig. 2 is the lateral view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is made specific descriptions;
As shown in Figure 1, 2, a kind of speed changer with bidirectional torsion vibration damper gear pair mainly is made up of transmission input shaft 1, straight pin 2, assembling and positioning pin 3, woodruff key 4, jack shaft constant mesh gear 5, damping disc 6, torsion spring 7.Assembly process need be used assembling and positioning pin 3, removes assembling and positioning pin 3 after straight pin 2, jack shaft constant mesh gear 5, damping disc 6, torsion spring 7 are located by connecting.Concrete working principle is: transmission input shaft 1 external motor, transmit torque to jack shaft constant mesh gear 5, jack shaft constant mesh gear 5 connects output by woodruff key 4, fixing straight pin 2 is arranged on the jack shaft constant mesh gear 5, damping disc 6 withstands straight pin 2 by torsion spring 7, when gear transmission stably the time, damping disc 6 stability of rotation rotate simultaneously by torsion spring 7 and jack shaft constant mesh gear 5, when jack shaft constant mesh gear 5 rotates the appearance fluctuation suddenly, damping disc 6 is because of the inertia of himself, make damping disc 6 to promote straight pin 2 by torsion spring 7, straight pin 2 connects jack shaft constant mesh gear 5, force jack shaft constant mesh gear 5 to trend towards original speed as far as possible, make the variation of rotating be tending towards minimum, and then the knock of the flank of tooth can not appear in gear again, finally eliminates speed changer idling noise.
Claims (2)
1. speed changer with bidirectional torsion vibration damper gear pair, speed changer is made up of gear pair some, it is characterized by: input shaft and jack shaft constant mesh gear are normal engagement, increase the bidirectional torsion vibration damper on the jack shaft constant mesh gear.
