Embodiment Construction

[0022] The dynamic simulation test method of the plastic support bearing for automobile suspension of the present invention is to place the bearing to be tested flat on the vertical test shaft, the test shaft can swing intermittently with the driving device, and the intermittent swing is provided by the multi-link in the driving device. The mechanism converts the rotation of the variable frequency motor into a swing within ±45° on the test shaft to simulate the actual motion state of the bearing under test. At the same time, a loading device is set on the bearing under test. The loading device includes axial loading and radial loading , Axial loading and radial loading are both implemented by a loading block placed on the bearing under test, wherein the axial loading is to set an axial force sensor on the loading block, and the axial force sensor is controlled by a fixed axial loading cylinder→ Loading block→the bearing under test implements axial loading. Radial loading is to ...

Abstract

The invention discloses a dynamic simulation test method of a plastic supporting bearing used in automobile suspension and a testing machine. The testing machine is composed of a drive unit, a loading unit, a bed and an optional environmental simulation test auxiliary unit; a transmission shafting 5 in the drive unite is fixed in a work table 16 of the bed 17, the lower end of the transmission shafting 5 is linked with a torque sensor 4, the upper end of the transmission shafting is linked with a coupling 15 and a test shaft 14 is fixed in a groove of the transmission shafting, a bearing to be tested 13 is arranged on the transmission shafting; a frame 6 is fixed on the work table, a radial loading oil cylinder 7 is horizontally fixed on the frame, a sensor 8 is arranged on the head part of the radial loading oil cylinder 7 and abuts on a loading head 9 on the side of a loading block 12, an axial loading oil cylinder 10 is vertically fixed on the frame, a sensor 11 is arranged on the head part of the axial loading oil cylinder 10 and abuts on the loading block, the loading block is arranged on the bearing to be tested; a heating test or a turbid water test can be chosen for the work table or the coupling. During test, a variable frequency motor 1 is directly connected with a reduction gear 2 to drive a multi-link mechanism 3 and converts into swing of the test shaft and drives the tested bearing, and a computer monitors the whole test process and records data.

Description

technical field [0001] The invention belongs to the technical field of bearing testing machines, and in particular relates to a dynamic simulation testing method and a testing machine for plastic supporting bearings used for automobile suspension. Background technique [0002] The bearings used for automobile suspension are plastic products, which are composed of upper and lower shells and inner cores. When used, they are installed in the automobile suspension strut assembly, and the upper and lower shells and inner cores form a rotating body. [0003] The test method and testing machine of this type of bearing are still blank in China, and the domestic literature has not yet seen the report of this type of bearing experiment. Traditional testing methods and testing machines have been unable to simulate the actual working conditions of this type of bearing, and there is no systematic testing method and testing machine for this type of bearing to test its performance and life...
