Problems solved by technology
[0004] At present, the judgment of the torsional clearance and sliding amount of the slipping pair of the steering intermediate shaft on the actual vehicle is mainly confirmed by experienced inspectors through the feel, which lacks scientificity and accuracy; the torsional clearance and the sliding amount of the slipping pair cannot be accurately determined. The size of the slippage cannot be ruled out in time whether it is the abnormal sound of the vehicle during the steering process due to the excessive torsional clearance and slippage of the steering intermediate shaft slip pair

The invention discloses an automobile steering intermediate shaft slip pair detection device and a detection method. The detection device comprises a main sensor transmitter, a main sensor receiver, asub sensor transmitter, a sub sensor receiver and a control mechanism; the main sensor transmitter is fixed on a spline portion of a steering intermediate shaft, and the main sensor receiver is fixedon a sleeve portion of the steering intermediate shaft; the main sensor transmitter cooperates with the main sensor receiver to obtain the twist clearance between the sleeve portion and the spline portion and the amount of sliding of both in the axial direction and the data is transmitted to the control mechanism; the sub sensor transmitter is fixed to the main sensor receiver, and the sub sensorreceiver is fixed to the main sensor transmitter. The device can timely and effectively detect the slip pair twist clearance and the sliding amount of the steering intermediate shaft so as to check and confirm the abnormal noise caused by the excessive sliding amount and the excessive slip pair twist clearance of the steering intermediate shaft.
Description
technical field [0001] The invention relates to the technical field of detection devices for auto parts, in particular to a detection device and a detection method for a steering intermediate shaft slip pair. Background technique [0002] With the development of truck-mounted vehicle technology, column-type electric power steering system (hereinafter referred to as CEPS) has gradually become popular due to its advantages of low cost, flexible layout space, and convenient maintenance. CEPS steering system mainly includes steering wheel, steering column, steering intermediate shaft and mechanical steering gear. [0003] The steering intermediate shaft is the transmission shaft that connects the steering column and the steering gear in the automobile steering system to transmit power. It usually consists of two upper and lower universal joint yokes and a slip pair that connects the upper and lower universal joint forks. As the CEPS boost increases, the steering intermediate sh...
