Description

Baffle for rubber bushing

Technical Field

The utility model relates to a damping rubber bush technical field specifically is a baffle for rubber bush.

Background

With the rapid development of automobile technology, people have higher and higher performance requirements on various aspects of automobiles, the vibration and noise of the automobiles, which are one of the performance indexes of the automobiles, are more and more prominent, the mass consumption is gradually rationalized, and the low oil consumption and the good comfort are required for the purchase concept of the automobiles. In order to adapt to the market variation trend, a lightweight rubber shock-absorbing bushing which meets the requirements of vehicle shock absorption, noise reduction and strength and simultaneously reduces the self weight of a vehicle is the current development direction. The rubber shock absorption bushing is generally composed of an outer pipe, a rubber main spring, an inner lining pipe and a baffle, the baffle is commonly a metal plate at present, see patent application with publication number CN110360255A, a stamped plate of the rubber shock absorption bushing needs to be riveted and fixed, and the processing operation is complex and self-significant.

Disclosure of Invention

Processing is complicated when solving current baffle and interior bushing pipe and being connected, the great problem of dead weight, the utility model provides a baffle for rubber bush, its connection operation that can simplify baffle and interior bushing pipe alleviates rubber bush's dead weight.

The technical scheme is as follows: the utility model provides a baffle for rubber bush, its includes the baffle body, it has the through-hole to open in the middle of the baffle body, its characterized in that, the baffle body is PA66+ GF 50%'s plastic slab, the baffle body openly is provided with C shape boss, the through-hole opening part at the baffle body back is provided with the chamfer, the baffle body with interior bushing pipe interference fit.

The baffle plate is further characterized in that the baffle plate body is a circular plate, and the diameter of the baffle plate body is smaller than or equal to the maximum outer diameter of the rubber shock absorption bushing.

Adopt the utility model discloses afterwards, change the baffle body into the working of plastics from the metalwork, reduced the dead weight of product to baffle body and interior bushing pipe interference fit have reduced the assembly difficulty, have simplified the operation.

Detailed Description

Referring to fig. 1, 2, 3, 4 and 5, the baffle for the rubber bushing comprises a baffle body 1, wherein a through hole 2 is formed in the middle of the baffle body 1, the baffle body 1 is a plastic plate with PA66+ GF50% and can meet rigidity requirements, a C-shaped boss 3 is arranged on the front face of the baffle body 1 and is used for supplementing a gap between an axial mounting surface and a counterpart, so that the rigidity of the baffle is increased, the axial stress of the baffle body 1 is uniform, and the C-shaped design brings a guide opening so as to play a role in guiding in an assembling process, and the guide opening is pressed in after being aligned with the boss on an assembly part, which is shown in fig. 6.

A chamfer 4 is arranged at the opening of the through hole 2 on the back of the baffle body 1, so that the press fitting is convenient, the baffle body 1 and the lining pipe 5 are in interference fit, 6 in the figure is a rubber component, and 7 is an outer pipe.

The baffle body 1 is a circular plate, and the diameter of the baffle body 1 is smaller than or equal to the maximum outer diameter of the rubber shock absorption bushing, and generally selected to be consistent with the maximum outer diameter.

Claims (2)

1. The utility model provides a baffle for rubber bush, its includes the baffle body, it has the through-hole to open in the middle of the baffle body, its characterized in that, the baffle body is PA66+ GF 50%'s plastic slab, the baffle body openly is provided with C shape boss, the through-hole opening part at the baffle body back is provided with the chamfer, the baffle body with interior bushing pipe interference fit.

2. The baffle plate for a rubber bushing according to claim 1, wherein the baffle plate body is a circular plate, and a diameter of the baffle plate body is equal to or less than a maximum outer diameter of the rubber damper bushing.
