Abstract
The utility model discloses a transmission shaft shock absorption device. The main body is a transmission shaft pipe. A piece of wave-shaped corrugated paper and a cavernous body are combined in the transmission shaft to absorb shock of the transmission shaft to reduce the shock. A layer of wave-shaped corrugated paper element is arranged on the inner wall of the transmission shaft pipe, and a layer of the sponge body is arranged on the wave-shaped corrugated paper element. A layer of single-face corrugated paper board is arranged on the sponge body layer. The wave-shaped corrugated paper element, the sponge body layer and the single-face corrugated paper board are fixedly connected in a mode of tight pressing and splicing. The transmission shaft shock absorption device is simple in structure, a prior built-in rubber shock absorption ring and a single shock absorption paper tube are removed, installation is more convenient compared with a prior device, the shock absorption and noise reduction effect is improved by 10%, stability when a car is in high-speed running is improved in a certain extent, besides, the mass ratio of a transmission shaft on a whole underpan is decreased due to use of the corrugated paper and the cavernous body, and energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of automobile chassis drive system part, the vibration damping equipment on especially a kind of transmission shaft.
Background technique
At present, the damping index of truck drive shaft is an important parameter in the Automobile Design process, and the transmission shaft damping solves the effective means of car load NVH problem.Common employing at present increases single paper tube in cardan-shaft tube or assembling built-in rubber damping block reaches effectiveness in vibration suppression, but test shows that the transmission shaft that adopts single vibration damping paper tube plays the effect of vibration damping noise reduction really in the 3000rpm/ timesharing, increase and exceed 4200rpm/ timesharing vibrating noise thereupon.As adopt the built-in rubber damping block to bring the difficult problem of assembling.The claimant has automobile assembling field work experience for many years, corrugated paper and the foam body purpose that make up reach vibration damping of design by certain vibration damping, absorbing are set on the inwall of truck drive shaft.
Present corrugated paper all is divided into V-arrangement and U-shaped, if it is unstable to use merely a certain corrugated paper can connect in being in contact with one another the process of break-in, the claimant is in order to address this problem, use two kinds of corrugated paper actings in conjunction, and connect two kinds of corrugated papers with foam body as packing, thereby reach the effect of better vibration damping, absorbing.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, we grope through long-term practice aborning, have designed a kind of transmission shaft damping device.
Technological scheme: in order to realize the foregoing invention purpose, the technological scheme that the utility model adopts is: a kind of transmission shaft damping device, main body is a cardan-shaft tube, utilize the combination of the corrugated paper of waveform and foam body to absorb the vibration of transmission shaft in described transmission shaft the inside, reduce vibration and noise.Concrete structure representation is as follows: the inwall of described cardan-shaft tube is provided with one deck waveform corrugating media, and described waveform corrugating media is provided with one deck foam body, and described foam body layer is provided with one deck single face corrugated board.Described waveform corrugating media, foam body layer and single face corrugated board are fixedly connected with by pressing bonding mode.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, this apparatus structure is simple, original built-in rubber damping ring and single absorbing paper tube have been cancelled, install more convenient than in the past and absorbing erasure effect aspect has improved 10%, improved to a certain extent the NVH performance rate of truck drive shaft and improved the comfort level that automobile is taken; What 2, the use of corrugated paper and foam body combination had avoided that rubber damping circle Yin Wendu, frequency, strain, the factor such as aging cause departs from.
Description of drawings
Fig. 1 is the structural representation of a kind of transmission shaft damping device of the utility model.
Embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, the technical program is elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of transmission shaft damping device of the utility model comprises cardan-shaft tube 1, and described cardan-shaft tube 1 inwall is provided with one deck waveform corrugating media 2, described waveform corrugating media 2 is provided with one deck foam body 3, and 3 layers of described foam bodies are provided with one deck single face corrugated board 4.Described waveform corrugating media 2 is the U-shaped corrugating media, and the inner chamber of the corresponding transmission shaft of the falt paper face of described single face corrugated board 4, and the wavy surface of described single face corrugated board 4 is connected with foam body and layer is pressed connection.3 layers of described waveform corrugating medias 2, foam body are fixedly connected with by pressing bonding mode with single face corrugated board 4.Be that the effect that comparable vibration damping in the past, shock-absorbing are shaken improves 10% by such transmission shaft inwall setting.
Claims (2)
1. transmission shaft damping device, comprise cardan-shaft tube (1), it is characterized in that: described cardan-shaft tube (1) inwall is provided with one deck waveform corrugating media (2), described waveform corrugating media (2) is provided with one deck foam body (3), and described foam body (3) layer is provided with one deck single face corrugated board (4).
2. a kind of transmission shaft damping device according to claim 1 is characterized in that: described waveform corrugating media (2), foam body (3) layer are fixedly connected with by pressing bonding mode with single face corrugated board (4).
