Abstract
The utility model relates to an adjustable type transmission shaft bump leveller. The adjustable type transmission shaft bump leveller comprises a bump leveler body. The bump leveller body comprises an annular rubber piece and a quality piece arranged in the inner portion of the rubber piece. An annular rubber piece hollow cavity is arranged in the inner portion of the rubber piece. A quality piece hollow cavity is arranged in the quality piece. A controlling wire is connected with an expansion sac. A controlling device is connected with the controlling wire. The adjustable type transmission shaft bump leveler has the advantages that dynamic vibration of a transmission system is effectively eliminated. Delivering of the vibration to a vehicle body is reduced. The noise vibration and harshness (NVH) performance of a vehicle is improved. The mode frequency can be adjusted continuously at the same time. Generation of the resonance problem is avoided. A quality (m) parameter and a rigidity (K) parameter can be adjusted at the same time. The adjustable type transmission shaft bump leveler has the advantages of being high in sensitivity, good in stability, simple in manufacturing material, low in cost, light in size structure, easy to be used in quantity production and the like. The adjustable type transmission shaft bump leveler is wide in application range and suitable for various vehicle types of a passenger car, a sports utility vehicle (SUV), a commercial vehicle and the like.
Description
Technical field
The utility model relates to the passenger car transmission system, and being applied to especially is a kind of adjustable transmission shaft bump leveller of passenger car transmission system.
Background technique
Along with automobile research and development technology and people's living standard improve constantly, people require also more and more higher to the riding comfort of automobile, noise and vibration is the key factor that affects travelling comfort, and the vibration of power train is one of main excitation source of vehicle body, it is the very large factor that affects car load noise, vibration and sound vibration roughness (NVH) quality.Therefore, the transmission shaft bump leveller just becomes the Main Means of eliminating drive line vibrations.But there are a lot of defects in the design of the transmission shaft bump leveller of most, and wherein main defect is as follows: (1) existing common bump leveller of transmission shaft just works for the excitation of single-frequency, can not effectively eliminate the vibrational excitation of Frequency; (2) existing most active vibration absorber complex structure, cost is higher, and, due to factors such as the special vibratility of transmission shaft and spatial constraints, existing active vibration absorber also is not suitable for the vibration problem of eliminating transmission shaft; (3) existing common bump leveller design frequency is single, regulating frequency automatically, and block rubber, after long-time the use, the situations such as aging distortion easily occur, may cause that this bump leveller frequency changes, thereby lose, eliminates original function of vibrating.
The model utility content
The purpose of this utility model is to provide a kind of adjustable transmission shaft bump leveller, to reach the purpose that is installed on transmission shaft and eliminates drive line vibrations.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of adjustable transmission shaft bump leveller, comprise the bump leveller body, and described bump leveller body comprises annular block rubber and the mass block of being located at block rubber inside, and described block rubber inside is provided with annular block rubber cavity, is provided with the mass block cavity in described mass block; Be provided with swelling bag in described mass block cavity.
Further, between described block rubber cavity and described mass block cavity, be provided with some cavity passage, in block rubber cavity and described mass block cavity, be filled with incompressible liquid.
Further, on described swelling bag, be connected with pilot, be connected with controller on pilot.
The beneficial effects of the utility model are: effectively eliminated the dynamic vibration of power train, reduced the transmission of vibration to vehicle body, lifting vehicle NVH performance, can regulate model frequency continuously, avoids resonance problem to produce simultaneously; Simultaneously quality of regulation (m) and rigidity (K) parameter, have sensitivity higher, good stability, and the making material is simple, with low cost, and volume structure is less, is easy to the advantages such as volume production use; Using scope is wide, is applicable to the various such as car, SUV, commercial car.
The accompanying drawing explanation
Below with reference to the accompanying drawings the utility model is described in further detail.
Fig. 1 is the structural representation sectional view of the described a kind of adjustable transmission shaft bump leveller of the utility model embodiment.
In figure:
1, block rubber; 2, mass block; 3, block rubber cavity; 4, mass block cavity; 5, swelling bag; 6, pilot.
Embodiment
As shown in Figure 1, the described a kind of adjustable transmission shaft bump leveller of the utility model embodiment, comprise the bump leveller body, described bump leveller body comprises annular block rubber 1 and is located at the mass block 2 of block rubber 1 inside, described block rubber 1 inside is provided with annular block rubber cavity 3, in described mass block 2, is provided with mass block cavity 4; Be provided with swelling bag 5 in described mass block cavity 4; Be provided with some cavity passage between described block rubber cavity 3 and described mass block cavity 4, in block rubber cavity 3 and described mass block cavity 4, be filled with incompressible liquid; Be connected with pilot 6 on described swelling bag 5, on pilot 6, be connected with controller.
During concrete the use, by the sensor of being located on passenger car, follow the tracks of the vibrational excitation frequency, controller sensor-lodging, calculating regulating frequency also control the rigidity k of bump leveller and the variation of quality m in real time, finally complete the frequency conversion function of bump leveller.
And the frequency of bump leveller is mainly controlled by bump leveller quality (m) and rigidity (k), as formula
shown in, block rubber 1 in the bump leveller body is between transmission shaft tube wall and bump leveller mass block 2, block rubber 1 is equipped with cavity with mass block 2, wherein block rubber cavity 3 communicates and is filled with incompressible liquid with mass block cavity 4, be provided with swelling bag 5 in bump leveller mass block cavity, between swelling bag 5 and controller, by pilot 6, be connected, electronic controller can be realized the adjusting to swelling bag 5 by pilot voltage signal size, thereby further by the expansion (or contraction) of swelling bag, liquid is discharged to (or suction) mass block cavity and realize the variation of rigidity and the quality of bump leveller, realize the designing requirement of bump leveller continuous frequency conversion.
And controller mainly gathers the engine crankshaft tach signal by sensor, the main order energizing frequency of calculation engine export the voltage signal of corresponding size after the controller sensor-lodging, thereby regulate the variation that swelling bag 5 is realized bump leveller rigidity and quality, carry out the continuous adjusting of bump leveller frequency.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
