Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] see figure 1 , which shows a friction torque measurement device 100 for a spool according to an embodiment of the present invention. The friction torque measuring device 100 includes a rotation conversion device 10 , a torque sensor device 20 and a preload device 30 . Specifically, the rotation conversion device 10 is used to drive and rotate the spool 50; the torque sensing device 20 is used to measure the friction torque of the spool 50 when rotating; the preload device 30 and the spool 50 are respectively connected to the torque sensing device 20 opposite ends of the . During the test, the spool 50 is assembled between the rotation conversion device 10 and the torque sensing device 20, and then the rotation conversion devic...

Abstract

The present invention discloses a friction moment measuring device used for a sliding column, and belongs to the automobile product test technology field. The friction moment measuring device comprises a rotation converting device used for driving and rotating the sliding column; a moment sensing device used for measuring the friction moment when the sliding column rotates; and a preloading device, wherein the preloading device and the sliding column are connected with the relative two ends of the moment sensing device respectively. At test, the sliding column is assembled between the rotation converting device and the moment sensing device, then the rotation converting device drives and rotates the sliding column, at the same time, the preloading device applies the preset pressure on the sliding column via the moment sensing device, and then the friction moment of the sliding column at rotation is measured via the moment sensing device.

Description

technical field [0001] The invention relates to the technical field of automobile product testing, in particular to a friction torque measuring device for a sliding column. Background technique [0002] Low-speed steering return performance plays an important role in the development process of handling stability, and it is also a road condition that ordinary customers use more. How to improve low-speed steering return performance and ensure customer satisfaction is an important issue. [0003] At present, the jig for measuring the friction torque of the strut can only measure the torque of the front suspension system of the whole vehicle, but cannot obtain the friction torque of a single strut assembly. Contents of the invention [0004] In order to solve at least one aspect of the above-mentioned problems and defects existing in the prior art, the present invention provides a friction torque measuring device for a sliding column. Described technical scheme is as follows:...
