A bearing ball joint

Abstract

The invention provides a bearing type spherical hinge comprising a spherical pin sleeve (1), a spherical pin seat (2), balls (3), a spherical pin (4) and a rolling way (5). The spherical pin seat (2)is provided with a plurality of ball installation holes (21). The balls (3) are movably installed in the ball installation holes (21). The rolling way (5) forms a hollow inner cavity and is fixedly installed in an inner cavity of the spherical pin sleeve (1). The spherical pin seat (2) is fixedly installed in the inner cavity of the rolling way (5). A spherical head portion of the spherical pin (4) is movably installed in the inner cavity of the spherical pin seat (2). When the bearing type spherical hinge is used under the conventional working conditions of normal temperature, light load, medium load and the like, the spherical hinge seat can bear the load, under the severe working conditions of heavy load, high temperature and the like, the balls can be switched to bear the load, in thisway, the bearing performance of the spherical hinge under different working conditions is greatly improved, and then the excellent-performance spherical hinge structure with a wide temperature domainand a wide load range is formed.

Description

technical field [0001] The invention relates to the field of spherical joint structure design, in particular to a bearing type spherical joint suitable for wide temperature range and wide load range occasions. Background technique [0002] In the process of design and development of spherical joint structures, especially in the development of spherical joints in automobile chassis, due to the different requirements of customers, spherical joint products must adapt to the needs of different temperature regions and different operating conditions. In terms of temperature, the short-term high temperature needs to reach 150°C, the long-term high temperature needs to reach 50°C, the short-term low temperature needs to reach -50°C, and the long-term low temperature needs to reach -20°C. Under the requirements of such a wide temperature range, the currently commonly used ball joint products have poor adaptability, especially in extreme ambient temperatures, due to the large attenuat...

AI Technical Summary

Problems solved by technology

Under the requirements of such a wide temperature range, the currently commonly used ball joint products have poor adaptability, especially in extreme ambient temperatures, due to the large attenuation of material properties, the ball joint cannot meet the functional requirements

At the same time, in terms of load, the existing spherical hinge products have limited strength. Although the strength can be increased by increasing the diameter of the ball to reduce the stress per unit area, it will inevitably lead to a large structure and cannot meet the layout of the installation space. Need, especially for heavy-duty, sporty models
