Abstract
The utility model provides a gear-shifting inhaul cable supporting assembly of an automotive transmission. The gear-shifting inhaul cable supporting assembly of the automotive transmission comprises a supporting frame body, shock-absorption sleeves and reinforcing sleeves, wherein the supporting frame body is provided with an installation part connected with the transmission, the installation part is provided with at least two installation holes, and the supporting frame body is further provided with a semi-opened limiting hole where a gear-shifting inhaul cable penetrates through. The shock-absorption sleeves are embedded in the installation holes, the longitudinal section of each shock-absorption sleeve is shaped like I, the two ends of each shock-absorption sleeve are tightly attached to the upper surface and the lower surface of the supporting frame body, one reinforcing sleeve is installed in each shock-absorption sleeve in a sleeved mode, and a bolt passing hole is reserved in the middle of each reinforcing sleeve. By adopting a rubber soft pad which is low in cost and simple in structure, the gear-shifting inhaul cable supporting assembly of the automotive transmission achieves the purposes of absorbing vibration noise and avoiding resonance intervals, and improves the comfort of a car.
Description
Technical field
The utility model belongs to the Automotive transmission technical field, is specifically related to the gear-shifting inhaul cable supporting structure of change-speed box.
Background technology
Along with the fast development of auto age, numerous clients improve constantly aspect quality requirements such as the dynamic property of automobile, safety, driving, traveling comforts.At first the operation of automobile needs engine ignition work to produce rotary power, then through turbine transformer or power-transfer clutch, passes to change-speed box, then by drive axle, passes to wheel driving Vehicle Driving Cycle.Driving system produces the sound of different frequency due to the parts mechanical vibration in the transferring power process, general gear-shifting inhaul cable support and change-speed box body adopt and are rigidly connected, mechanical vibration sound just can be by the support rigid of transmission to gear-shifting inhaul cable like this, when gear-shifting inhaul cable shakes identical with change-speed box body vibration frequency, resonance effect occurs, and vibrations sound is exaggerated, and the sound quality descends, then import operator's compartment into along drag-line, affect passenger comfort.Therefore,, in order to guarantee sound quality, need to improve the gear-shifting inhaul cable support, with the propagation path to sound, be optimized.
Summary of the invention
The purpose of this utility model has been to provide a kind of shifting vehicle gearbox cable support assembly, and one of purpose is effectively to weaken driving system vibrations noise, and two of purpose is to make it simple in structure, compact and easy to assembly.
The technical solution of the utility model is as follows:
A kind of shifting vehicle gearbox cable support assembly, it comprises rack body, shock-absorbing sleeve and reinforcing sleeve, rack body has the installation portion that is connected with change-speed box, is provided with at least two mounting holes on this installation portion, also has and holds the half opening spacing hole that gear-shifting inhaul cable passes.It is characterized in that described shock-absorbing sleeve is inlaid in mounting hole, its vertical section is I shape, and the upper and lower surface of rack body is close at its two ends, and described reinforcing sleeve is contained in shock-absorbing sleeve, and bolt through-hole is left in centre.Like this, by shock-absorbing sleeve, can avoid the installation position of rack body directly with the change-speed box rigidity, to contact, can block the transmission sound path, weaken the vibrations noise, promote the HAV performance of automobile.And the setting of reinforcing sleeve can retrain the distortion of shock-absorbing sleeve, facilitates hold-down bolt.
Further, described reinforcing sleeve is designed to the structure that vertical section is T shape, it inserts shock-absorbing sleeve from bottom to top, and head is pressed on the lower surface of shock-absorbing sleeve, can further increase the effect that weakens noise, and guarantee bolted firmly qualitative.
Further, described shock-absorbing sleeve is rubber shock-absorbing sleeve, can embed in gearshift support mounting hole by crimp like this, and is easy for installation.
The utility model is by adopting lower cost, rubber mount simple in structure, realized decay vibrations noises, avoided the purpose of interval of resonance, improved car comfort.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is assembling schematic diagram of the present utility model, has expressed the assembly features between shock-absorbing sleeve, reinforcing sleeve, gearshift support three.
The specific embodiment
Below in conjunction with the explanation accompanying drawing, to further statement in detail of the technical solution of the utility model.
As can be seen from Figure 1, the gear-shifting inhaul cable bracket assembly comprises gearshift rack body 1, shock-absorbing sleeve 2, reinforcing sleeve 3, and rack body is L shaped, and the bottom surface of L is the installation portion that is connected with change-speed box, triangular in shapely on it is distributed with 3 mounting holes.Vertical section has been installed in mounting hole be the rubber shock-absorbing sleeve 2 of I shape.It is the reinforcing sleeve 3 of T shape that vertical section has been installed again in shock-absorbing sleeve 2.
Referring to Fig. 2, during installation, first rubber shock-absorbing 2 is embedded in gearshift support mounting hole by crimp, then rely on the i shaped cross section of shock-absorbing sleeve naturally to recover to be supported in mounting hole, again the rigidity reinforcing sleeve is inserted in the damping trepanning from bottom to top, prevent that shock-absorbing sleeve from radially dwindling, make mounting hole, damping trepanning, reinforcing sleeve be in coaxial state.In gear-shifting inhaul cable support installation process, hold-down bolt is screwed down, and at first pushes the shock-absorbing sleeve upper surface, and the shock-absorbing sleeve extrusion is close to the gear-shifting inhaul cable rack outer surface with state's support of surely shifting gears by two of shock-absorbing sleeve up and down inner end surface.
Sound transmission path: driving system parts vibration sounding, sound passes to the gear-shifting inhaul cable support by mission case, the damping cushion driving system vibrations noise of decaying in this course, prevent that sound from producing excitation in communication process, then the support of shifting gears passes to gear-shifting inhaul cable, be delivered to again selector, enter in operator's compartment finally.
In this structure, the performance of the rubber by selecting shock-absorbing sleeve, as hardness, stretch breaking strength, elongation rate of tensile failure, compressive permanent set, hot air aging etc., can for not in unison quality adjust to meet the requirement of vibrations sound attenuating.
