Description
Technical field
The utility model relates to a kind of manual transmission and selects gear shift pulling cable, is applicable to various cars and uses by manual transmission; And comprise the automobile gearbox that this selects gear shift pulling cable.
Background technique
Current car generally adopts push-pull cable to realize gearbox selector gear shift function by manual transmission.Driver promotes or pulls drag-line by handling gear mechanism in operator cabin, realizes gear change in gearbox.
Drag-line generally has two, and one is for handling the gear selecting of gearbox, and another root is used for handling the gearshift of gearbox.Every drag-line is all comprised of cable core and outer sleeve, and cable core is being wrapped by outer sleeve, can be in outer sleeve relative sliding, for realizing the push-and-pull function of drag-line.And the Main Function of outer sleeve is to protect cable core not to be subject to foreign impacts or corrosion, outer sleeve is generally in state of rest.On outer sleeve, generally can be fixed with the weight block that quantity does not wait, be used for reducing the vibrations of drag-line.Concrete implementer's case, has relevant description in Chinese patent application file No. CN200920264269.5 and No. CN201120096420.6.
In these technological schemes, in order effectively to reduce the vibrations of drag-line, the weight block quality arranging on drag-line outer sleeve is generally larger, has so also just increased the overall quality of drag-line.And under many circumstances, the vibrations of engine compartment are all that the cable core by drag-line is delivered to cockpit, rather than shake by outer sleeve transmission.
Like this, due to the vibrations of gearbox, although there is weight block on some drag-line outer sleeve, still have the sound that drag-line cable core and outer sleeve knock.Therefore can say so, current stayed structure is not obvious to the inhibition of vibrations.
Therefore, necessaryly develop a kind of novel gearbox selector gear shift pulling cable, overcome defect of the prior art.
Model utility content
The purpose of this utility model is to provide a kind of novel automobile gearbox to select gear shift pulling cable, and it can compact stayed structure, reduces drag-line weight, and can improve the damping performance of drag-line.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of automobile gearbox selects gear shift pulling cable, and it comprises gear selecting drag-line, gear-shifting inhaul cable and damping device.Wherein said damping device comprises damper element, and the two ends of this damper element are connected with gear-shifting inhaul cable with gear selecting drag-line by bindiny mechanism respectively.
Further, described damper element comprises damping spring.
Further, described bindiny mechanism comprises slide block and connecting rod, and wherein said slide block is arranged on described drag-line, and described slide block is connected with described damper element by described connecting rod.
Further, described slide block set is connected on the cable core of described drag-line.
Further, described connecting rod joins by mode and the described slide block of globular hinge head.
Further, it also comprises sleeve, and this damper element is sealed to be arranged in described sleeve.
Further, in described sleeve, be provided with damping fluid.
The utility model also provides a kind of automobile gearbox, and its automobile gearbox including described in aforementioned any one or multinomial technological scheme selects gear shift pulling cable.
With respect to prior art, the beneficial effects of the utility model are: the damper mechanism adopting due to drag-line acts directly on drag-line cable core, therefore, can effectively suppress the vibrations that power assembly passes over to operator cabin by drag-line.
Further, because damper mechanism can not only pass through quality sleeve vibration-inhibition, and can also be by damping spring and damping fluid absorbing vibration energy, therefore, the effect of damping is better than the general drag-line of alone mass block.Simultaneously because the volume of damper mechanism is little, lighter weight, can also further reduce the quality of whole drag-line, is conducive to improve car load fuel economy.

Embodiment
Below with reference to drawings and Examples, the automobile gearbox that the mode of execution that the utility model is related to provides selects gear shift pulling cable technological scheme to be described in further detail.
Refer to shown in Fig. 1 and Fig. 2, a kind of automobile gearbox selects gear shift pulling cable, it comprises gear selecting drag-line 10, gear-shifting inhaul cable 12, damping device 2 and dustproof silently 3, this block selecting drag-line 10 and gear-shifting inhaul cable 12 dustproof silently pass 3 from this, it comprises outer sleeve 5 and is arranged on the drag-line cable core 7 in outer sleeve, and one end of this block selecting drag-line 10 and gear-shifting inhaul cable 12 is set to gearbox joint 6, and the other end is set to gear end connector 8.Dustproof silently 3 by support frame and rubber filling thing, formed.Wherein, please refer to shown in Fig. 2, damping device 2 comprises damping spring 22, sleeve 24, connecting rod 23, slide block 25.
Wherein, damping spring 22 is sealed to be arranged in sleeve 24, and sleeve 24 inside are cavitys, are full of damping fluid in cavity.The two ends of damping spring 22 are fixedly connected with pair of links 23 respectively, and by globular hinge head, each is connected with a slide block 25 each connecting rod 23 respectively simultaneously, and slide block 25 is to be socketed in respectively on the cable core 7 of drag-line 10,12.
When power assembly shakes by drag-line transmission, the vibrations meeting of drag-line is delivered to damping spring 22 by slide block 25 and connecting rod 23, and damping spring 22 shakes snubber by part and falls.Meanwhile, sleeve 24 is aluminium alloy castingses, has certain quality, and the weight of sleeve 24 also acts on drag-line 10,12 cable cores by connecting rod 23, suppresses the vibrations of drag-line cable core 7.
When drag-line shakes, connecting rod 23 is subject to the effect of drag-line vibrations and does axial relative vibration, in damping spring 22 buffering connecting rod 23 axial vibrations, the viscosity of the damping fluid in its external sleeve 24 cavitys also can block the vibrations of connecting rod 23 simultaneously, plays the effect of absorbing vibration energy.
The damper mechanism that the utility model relates to connects the cable core of gear selecting drag-line and gear-shifting inhaul cable, and this mechanism adopts spring connecting mechanism, plays the effect of damping, buffering.And, in mechanism, configuring a sleeve, sleeve itself has certain weight, and its gravity acts on by connecting rod on the cable core that selects gear shift pulling cable, and under equal vibration stimulus, due to the impact of sleeve gravity, the Oscillation Amplitude of the cable core of drag-line reduces.
Meanwhile, the cavity inside in sleeve is full of damping fluid, is used for absorbing the vibrations that drag-line passes over.Manual transmission of the present utility model is selected gear shift pulling cable compact structure, has improved the performance aspect vibration noise, strengthens the travelling comfort of driving.
Technical scope of the present utility model is not only confined to the content in above-mentioned explanation, those skilled in the art can not depart under the prerequisite of the utility model technological thought, above-described embodiment is carried out to various deformation and modification, and these distortion and revise to work as and belong in scope of the present utility model.
