Problems solved by technology

[0003] At present, for the detection of the torsional clearance of the steering intermediate shaft, it is mainly confirmed by experienced inspectors through hand feeling, which lacks scientificity and accuracy; some are also measured by dial indicators and counterweights, but there are large personnel operating errors , and can only read the torsional gap under a certain torque, and cannot obtain the gap curve under continuous torque

Abstract

The invention relates to the automobile part detection apparatus technology field and discloses an automotive steering intermediate shaft torsion gap detection device. The device comprises a detection pedestal, a driving connection portion connected to an intermediate shaft driving end and at least one group of clamping portions. A PC, a fixing stand column connected to the driving connection portion, a sensor support and a fixing connection portion connected to an intermediate shaft fixing end are fixed to the detection pedestal. Displacement sensors which form one-to-one correspondence with the clamping portions are fixed to the sensor support. The driving connection portion is provided with a torque sensor and a driving motor. Each clamping portion comprises an intermediate shaft clamping end, a connecting pipe and a connecting rod which is vertically connected between the intermediate shaft clamping end and the connecting pipe. An axis of the connecting pipe is vertical to an axis of the intermediate shaft. A push rod of each displacement sensor is connected into the connecting pipe. The PC is electrically connected to the displacement sensors, the torque sensor and the driving motor respectively. By using the detection apparatus, changing curves of twisting angles of each portion on the intermediate shaft under continuous torque effects can be conveniently and accurately acquired.

Description

Technical field [0001] The invention relates to the technical field of detection devices for automobile parts, in particular to a detection device for torsion gaps of automobile steering intermediate shafts. Background technique [0002] The automobile steering intermediate shaft is a transmission shaft that connects the steering column and the steering gear to transmit power in the automobile steering system. The transmission shaft is usually composed of two upper and lower universal joint forks and two middle shaft tubes. If there is a large torsion gap between the above-mentioned parts of the steering shaft, abnormal noise will be generated when vibrating or changing direction, causing customer dissatisfaction. Therefore, it is necessary to control the size of the steering shaft torsion gap through torsion gap detection to ensure that the product meets the design Claim. [0003] At present, the torsion gap detection of the steering intermediate shaft is mainly confirmed by expe...
