Embodiment
The invention provides a kind of gearshift mechanism of manual transmission, get on conduct vibrations to the gear shifting handle of effective blocking-up balancing weight.
The basic thought that the present invention solves the problems of the technologies described above is: in the gearshift mechanism of automotive transmission, be provided with a balancing weight connecting plate that can rotate freely around certain shift shaft that is connected with gearbox case, the balancing weight connecting plate can be driven it by the rotation that balancing weight is stirred pin and rotate around the swinging strut bolt.Balancing weight is stirred pin and is connected with the shift shaft of gearshift mechanism, balancing weight is connected on the gear shift case by the swinging strut bolt, bolt compresses the opening of balancing weight connecting plate, and balancing weight and its connecting plate of being compressed by bolt are rotated freely around the swinging strut bolt.Since balancing weight not and gear shifting rotary arm directly connect, shift shaft except gearshift procedure with balancing weight without any contact, conduct vibrations to the gear shifting handle of effectively having blocked balancing weight gets on.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
See also Fig. 1, the gearshift mechanism structural representation of the manual transmission that Fig. 1 provides for the embodiment of the invention.
Wherein, 1 is shift shaft, and 2 for the gear shift case, and 3 is gear shifting rotary arm, and 4 is balancing weight, and 5 is the balancing weight connecting plate, and 6 stir pin for balancing weight, and 7 is plastic bushing, and 8 is the swinging strut bolt.
The present invention is to provide a kind of gearshift mechanism of manual transmission, it has a rotatable shift shaft 1 with being contained on the gear shift case 2 with moving axially, shift shaft 1 has a rotatable gear shifting rotary arm 3 that is fixedly connected with it, and this gear shifting rotary arm 3 is connected in kinology with the interior hand-gear shift lever of operator cabin; Also have in addition one can be in gearshift procedure just and gear shifting rotary arm 3 come in contact the balancing weight 4 of motion, balancing weight 4 is by balancing weight connecting plate 5, balancing weight stirs pin 6 and gear shifting rotary arm 3 indirectly couples together, balancing weight 4 can improve the rotation inertia moment of shift shaft 1, in order in each gear gearshift procedure, reduce the peak value of the berth-changing strength felt at the hand shift handle, in whole gearshift mechanism balancing weight 4 not and shift shaft 1 be rigidly connected, the square hole that balancing weight is stirred plastic bushing 7 on pin 6 and the balancing weight connecting plate 5 is again Spielpassung, so be the relation that does not have active force when shift shaft 1 axially moves and between the balancing weight 4, if the words that balancing weight 4 and shift shaft 1 link together, the mass effect of balancing weight 4 will be applied on the shift shaft 1, can cause harmful effect to gear-selecting transposition, make the gross weight of mobile whole assembly very large, if adopt the mode that is rigidly connected, in vehicle traveling process or other reasons is when causing balancing weight 4 vibration, because the mass effect of balancing weight 4 can be aggravated the vibration of shift shaft, will cause like this shake that has the hand shift handle that kinology is connected with gear shifting rotary arm 3, because the leverage meeting causes the vibration of hand shift handle more severe, travelling comfort and the gear shift travelling comfort of vehicle drive are reduced greatly, can cause out of supplyly in the more serious situation, finally cause automobile storage in potential safety hazard.The balancing weight Placement of narrating in the present embodiment is Spielpassung, both are the independent individualities that separate fully when not gear shift, there is not each other any contact, so just cut off balancing weight and vibrated the transfer route that passes to gear shifting handle, vibration just has been directly passed on the gear shift case that links together with mission case in the place of swinging strut, the vibration of balancing weight almost can be ignored with respect to the speed changer that fixes, and has so just effectively solved because the gear shifting handle jitter problem that balancing weight self vibration causes.
Gear shifting rotary arm 3 force bearing points (being the point that gear shifting rotary arm 3 is connected with gear shift pulling cable) are less than balancing weight to the distance of shift shaft 1 and stir pin 6 to the distance of shift shaft 1, gear shifting rotary arm 3 and shift shaft 5 are rigidly connected, gear shifting rotary arm 3 and balancing weight are stirred again linking together of rigidity of pin 6, balancing weight is stirred pin 6 and is rotated with the rotation of shift shaft 1, balancing weight stir pin 6 with the rotation amplitude in shift shaft 1 rotation process than large many of the rotation amplitude of gear shifting rotary arm 3, played gear shifting rotary arm 3 is rotated the effect of amplifying, the vehicle driver only needs very little distance of mobile gear shifting handle will make balancing weight stir pin 6 and rotates very large amplitude like this.
Balancing weight is stirred pin 6 and is rotated along with the rotation of shift shaft 1, stir at balancing weight under the drive of pin 6, balancing weight 4 rotates around swinging strut bolt 8 with balancing weight connecting plate 5, and balancing weight stir pin 6 to the distance of shift shaft 1 rotating center than stirring square hole that pin 6 cooperates to large many of the distance of swinging strut bolt 8 with balancing weight on the balancing weight connecting plate 5, balancing weight 4 is stirred at balancing weight under the drive of pin 6 around the angle of swinging strut bolt 8 rotations and is stirred large many of angle that pin 6 turns over around shift shaft 1 rotating center than balancing weight, and the rotary action of shift shaft 1 is stirred pin 6 by balancing weight and driven balancing weights 4 and rotate around swinging strut bolt 8 and obtained amplification like this.Just can make balancing weight 4 obtain a very large angle of swing in very low-angle situation of shift shaft 1 rotation, play shift shaft 1 is rotated the effect of amplifying, that the effect of balancing weight 4 can be brought into play is better, makes gear shift more comfortable.In addition above-mentioned amplification, the rotation of gear shifting rotary arm has been exaggerated twice in the whole gearshift procedure, balancing weight 4 can be increased effect performance very good of shift shafts 1 rotary inertia.
Gear shifting rotary arm 3 force bearing points (being the point that gear shifting rotary arm is connected with gear shift pulling cable) are less than balancing weight to the distance of shift shaft 1 and stir pin 6 to the distance of shift shaft 1, gear shifting rotary arm 3 and balancing weight are stirred linking together of pin (6) rigidity, it is again that two of being separated from each other are independently individual when not having gear shift that balancing weight is stirred pin 6 and balancing weight connecting plate 5, so just can effectively solve because the twisting of the caused gear shifting rotary arm 3 of balancing weight 4 vibrations, and then solved in the Vehicle Driving Cycle process jitter problem of gear shifting handle in the non-gear shift situation, even the vibration that balancing weight 4 causes for a certain reason or wave and do not blocked fully, or the gear shifting handle that some vibration is passed in the operator cabin gets on, but stir the distance relation of pin 6 and shift shaft 1 rotating center according to above-mentioned gear shifting rotary arm 3 and balancing weight, dwindled a lot when the transmission that the vibration that we are not difficult to draw balancing weight 4 is stirred pin 6 through balancing weight finally arrives gear shifting rotary arm 3 force bearing point, move very large apart from gear shifting rotary arm 3 force bearing points mobile very little distance just because balancing weight is stirred pin 6, it is just little many to be delivered to the vibration on the gear shifting handle in the operator cabin, the shake of the gear shifting handle that balancing weight 4 vibrations cause so this point has also further effectively reduced has increased the travelling comfort of driving.
The designed manual speed transmission shifting mechanism of the present invention is compared with traditional manual speed transmission shifting mechanism and is had the following advantages: at first be that rotary action with gear shifting rotary arm is through twice amplification, make balancing weight under the little rotation of gear shifting rotary arm, just can obtain very large rotation angle, make the balancing weight of same quality obtain larger rotation torque, the another one major advantage is exactly to have solved in the balancing weight arrangement of original traditional form because the shake of the gear shifting handle that balancing weight self vibration causes, driving comfortability and gear shift travelling comfort are improved greatly, also greatly reduced simultaneously because the risk out of supply that the violent shake of gear shifting handle may cause.More comfortable than traditional speed changer, more reliable in the use.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and other embodiments' difference that identical similar part is mutually referring to getting final product between each embodiment.
