Upper bracket and manufacturing method thereof

Abstract

Provided is an upper support and a method for producing same, wherein the upper support is not necessary to cut the outer peripheral surface of an inner fitting in order to fix a rebound stopper fitting, the production cost of the upper support can be reduced, a swaging operation can be easily performed by a small force, and the rebound stopper fitting can be firmly secured to the inner fitting in the rotational direction. In the upper support provided between a vehicle body and a shock absorber, which prevents vibrations using the elastic deformation of a rubber elastic element, projected fitting pieces (58) are partially provided on the top end surface of an inner fitting (12) in the circumferential direction, and are upwardly projected by a length larger than the thickness of a rebound stopper fitting (18), and recessed portions (66) corresponding to the projected fitting pieces (58) are provided in the rebound stopper fitting (18). While the projected fitting pieces (58) are upwardly inserted and fitted to the recessed portions (66), the portions of the projected fitting pieces that are exposed on the top surface of the rebound stopper fitting (18) are folded and swaged, to secure the rebound stopper fitting (18) to the top portion of the inner fitting.

Description

technical field [0001] The invention relates to an upper bracket which elastically connects the piston rod of the shock absorber of the suspension and the car body and plays a role of vibration isolation between them. Background technique [0002] Conventionally, in a vehicle, an upper bracket is used to elastically connect a piston rod of a shock absorber serving as a suspension element to the vehicle body, and the vibration isolation function of the upper bracket prevents or suppresses transmission of vibration from the shock absorber to the vehicle body. [0003] In the past, various types and forms of members have been known as the upper bracket, and as one of them, such an upper bracket is known, that is, it includes: (a) a cylindrical inner fitting whose upper surface is an open shape; b) outer fittings, which are arranged radially outside inner fittings; (c) rubber elastic bodies, which connect these inner fittings and outer fittings; (d) rebound stop fittings, which ...

AI Technical Summary

Problems solved by technology

[0026] However, in this case, the fixing force and holding force in the rotation direction are naturally limited, and it is difficult to fix the inner fitting 202 and the rebound stop fitting 208 sufficiently firmly in the rotation direction.
