Abstract
The utility model discloses a damping support in the middle of a transmission shaft. The damping support comprises an outer support and a rubber ring. The rubber ring has two layers, namely, a rubber outer ring and a rubber inner ring. Three damping springs are evenly arranged on the round rubber inner ring. Therefore, the rubber inner ring and the rubber outer ring are arranged on the outer support, a damping effect during an operation process of the transmission shaft is remarkably improved, the damping springs are arranged on the rubber inner ring, additional dynamic pressure generated by rotation of the transmission shaft is reduced, damage to related parts is decreased to a certain degree, and operation efficiency is improved.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, especially a kind of middle damping frame of propeller-shaft that is arranged at.
Background technology
Propeller-shaft is the vitals in the car assembling, transmission shaft can be at two between centers in different axle center, even the two between centers transferring power that constantly change of relative position in the course of the work, connect every accessory and circular object accessory removable or that rotate, generally all use light and the good alloy pipe of resistance to torsion is made.
The scooter per minute is thousands of to be turned because it turns, and can cause that because rotating the additional kinetic pressure that produces transmission shaft and correlated parts thereof produce vibration and noise.The amplitude when if the amplitude of vibration approaches resonance, the destruction that then can cause transmission shaft and correlated parts thereof, the decline in intensity, efficient and life-span.The applicant makes improvement according to the characteristics of transmission shaft at the transmission shaft support, utilizes support to subdue vibration and noise that transmission shaft produces in operational process.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, we grope through long-term practice aborning, have designed the middle shock bracket of a kind of transmission shaft.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is: shock bracket in the middle of a kind of transmission shaft, comprise the support outer bracket and be arranged on the interior rubber ring of support outer bracket, described rubber ring is divided into two-layer, be respectively rubber outer ring and rubber inner ring, described rubber inner ring is provided with damping spring.Described rubber inner ring is rounded, evenly is provided with three damping springs on the rubber inner ring.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, in the support outer bracket rubber inner ring and rubber outer ring are set, have significantly promoted the anti seismic efficiency of transmission shaft in operational process; 2, at rubber ring damping spring is set, has reduced because transmission shaft rotates the additional kinetic pressure that produces, the destruction of having reduced to a certain extent correlated parts has increased operating efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of shock bracket in the middle of a kind of transmission shaft of the utility model.
The specific 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, shock bracket in the middle of a kind of transmission shaft of the utility model comprises support outer bracket 2 and rubber ring, described support outer bracket 2 takes the shape of the letter U, described rubber ring is arranged in the support outer bracket 2, and described rubber ring is divided into rubber outer ring 1 and rubber inner ring 3, and described rubber inner ring 3 is provided with damping spring 4.
Be provided with on the described rubber inner ring 3 on 4, three damping springs of three damping springs, the 4 even distribution rubber inner rings, mutually firmly balanced, combined action reaches the purpose of vibration damping.
Claims (2)
1. shock bracket in the middle of the transmission shaft, comprise support outer bracket (2) and be arranged on the interior rubber ring of support outer bracket (2), it is characterized in that: described rubber ring is divided into rubber outer ring (1) and rubber inner ring (3), and described rubber inner ring (3) is provided with damping spring (4).
2. shock bracket in the middle of a kind of transmission shaft according to claim 1 is characterized in that: be provided with three damping springs (4) on the described rubber inner ring (3).
