abs bearing testing machine

Abstract

The invention belongs to the technical field of bearing detection and provides an ABS bearing testing machine. The proposed ABS bearing testing machine has a working box (15); the working box (15) is provided with a plurality of valve blocks (5) for placing ABS bearings; the corresponding ABS bearing is provided with a speed control mechanism, a load control mechanism and a temperature control mechanism. Control mechanism; the servo driver (16) of the rotational speed control mechanism is respectively set corresponding to each ABS bearing; the servo driver (16) and the programmable controller (3); the load control mechanism includes a loading oil tank (13), a proportional amplifier, a proportional overflow flow valve and overflow valve; the temperature control mechanism has a high and low temperature test chamber (14); the invention realizes the purpose of testing multiple sets of bearings at the same time, solves the requirements for testing and testing a large number of ABS bearings and installs them in the valve block The ABS bearing cannot detect the difficult problem.

Description

technical field [0001] The invention belongs to the technical field of bearing detection, and in particular relates to an ABS bearing testing machine, in particular to a testing machine for carrying out life tests and detection, analysis and control on multiple sets of ABS bearings within the same time period. Background technique [0002] The ABS bearing is an important part of the anti-lock brake system. The test requirements for the life test of the ABC bearing are: the pressure of the oil inlet of the valve block is 0.8Mpa, and the pressure of the oil outlet of the valve block is 30-220bar oil pressure; The ambient temperature is between minus 40 degrees and 120 degrees; in the process of life test and detection of the ABC bearing installed in the valve block, it is necessary to simulate 7 kinds of ambient temperatures, and under 10 kinds of oil pressure load conditions, it can meet the requirements of 2 seconds Acceleration + 10 seconds to run + 1 second to decelerate +...

Problems solved by technology

[0002] The ABS bearing is an important part of the anti-lock brake system. The test requirements for the life test of the ABC bearing are: the pressure of the oil inlet of the valve block is 0.8Mpa, and the pressure of the oil outlet of the valve block is 30-220bar oil pressure; The ambient temperature is between minus 40 degrees and 120 degrees; in the process of life test and detection of the ABC bearing installed in the valve block, it is necessary to simulate 7 kinds of ambient temperatures, and under 10 kinds of oil pressure load conditions, it can meet the requirements of 2 seconds Acceleration + 10 seconds to run + 1 second to decelerate + 10 seconds to stop; however, in the prior art, the equipment that can detect ABS bearings under the above experimental requirements is only available in Germany, but the German testing equipment can only test one at a time. Sets of ABS bearings are tested and expensive

[0003] ABS bearings are generally installed in a metal valve block with a square structure. The valve block has a valve block oil inlet and a valve block oil outlet; the valve block oil inlet is two: valve block oil inlet A and valve block Oil inlet B; however, the ABS bearing installed in the valve block cannot be detected in the prior art
