Embodiment
The utility model provides a kind of gearshift mechanism of manual transmission, gets on conduct vibrations to the gear shifting handle of effective blocking-up balancing weight.
The basic thought that the utility model 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.Because balancing weight directly is not connected with gear shifting rotary arm, shift shaft except that 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 among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1, the gearshift mechanism structural representation of the manual transmission that Fig. 1 provides for the utility model embodiment.
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 utility model provides a kind of gearshift mechanism of manual transmission, it have one rotatable and can be contained in shift shaft 1 on the gear shift case 2 with moving axially, shift shaft 1 has a rotatable gear shifting rotary arm 3 of fixedlying connected with it, and this gear shifting rotary arm 3 is connected on 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 is stirred pin 6 and gear shifting rotary arm 3 indirect coupling together, balancing weight 4 can improve the rotation inertia moment of shift shaft 1, so that in each gear gearshift procedure, reduce the peak value of the berth-changing strength on the hand shift handle, felt, 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 a 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 affact on the shift shaft 1, can cause harmful effect to the gear selecting transposition, make the gross weight of mobile whole assembly very big, 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 the shake that has the hand shift handle that kinology is connected with gear shifting rotary arm 3 like this, because the leverage meeting causes the vibration of hand shift handle severe more, the travelling comfort and the gear shift travelling comfort of vehicle drive are reduced greatly, more can cause out of supplyly under the serious situation, finally cause automobile storage in potential safety hazard.The balancing weight Placement of narrating in the present embodiment is a Spielpassung, both are the independent individualities that separate fully when not gear shift, there is not any contact each other, so just cut off the transfer route of balancing weight vibration transfer 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 is caused.
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 the distance of pin 6 to 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 pin 6 linking together of rigidity again, 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 big 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 big 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 big 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 big 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 big angle of swing under 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.Above-mentioned in addition amplification, the rotation of gear shifting rotary arm has been exaggerated twice in the whole gearshift procedure, and that the effect of balancing weight 4 increase shift shafts 1 rotary inertia can be brought into play is very good.
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 the distance of pin 6 to 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 process jitter problem of gear shifting handle under 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 points, because balancing weight is stirred pin 6 and is moved and very big just move a very little distance apart from gear shifting rotary arm 3 force bearing points, 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 are caused so this point has also further effectively reduced has increased the travelling comfort of driving.
The designed manual speed transmission shifting mechanism of this patent 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 big rotation angle, make the balancing weight of same quality obtain bigger 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 is caused, driving comfortability and gear shift travelling comfort are improved greatly, also reduced greatly 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 all is and other embodiments' difference that identical similar part is mutually referring to getting final product between each embodiment.
