Problems solved by technology

At present, there are very few testing equipments for the four-way adjustment durability of the steering column. Some steering column manufacturers use manual testing machines. The existing automatic testing equipment for the adjustment and durability of the steering column also has single function, complex structure, and inaccurate simulation. Human operation on the steering wheel, inaccurate measured data, no reusability, and no wide applicability to various types of columns, etc. These problems limit the overall improvement of the steering column adjustment durability testing technology

Embodiment 1

[0022] Embodiment one: see figure 1 , the automobile steering column adjustment durability test machine, including the test bench frame 1, the tested column assembly 2, the axial adjustment device 3, the radial adjustment device 4, the adjustable clamping device 5, the unlocking device 6, And a data acquisition and processing system; it is characterized in that: the radial adjustment device 4 is fixedly connected on the test bench frame 1, one end of the axial adjustment device 3 is hinged with the test bench frame 1, and the other end is connected with the radial adjustment device 4 through a pin, The pipe string clamping adjustable device 5 is fixed on the test bench frame 1, used to clamp the tested pipe string assembly 2, and adjust the position of the tested pipe string assembly 2, so that the output end of the tested pipe string assembly 2 is in line with the The axial adjustment device 3 is connected, and the unlocking device 6 is installed on the axial adjustment devic...

Embodiment 2

[0023] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0024] The structure of the test bench frame 1 is as follows: a cuboid frame is spliced ​​by aluminum alloy profiles, and two pairs of short profiles are respectively installed on the front and back of the frame. 13 is used to install the adjustable pipe string clamping device 5 .

[0025] The structure of the tested pipe string assembly 2 is as follows: the test piece bracket 23 is fixedly connected to the support of the pipe string test piece 21, and the output end of the pipe string test piece 21 is fixedly connected to the inertial disk 22 which is equivalent to a steering wheel.

[0026]The structure of the axial adjustment device 3 is: two pairs of one long and one short aluminum profiles are fixed vertically, and are respectively fixed to the two ends of an aluminum profile to form an L-shaped bracket 31, and the two sides of the L-shaped bracket 31 Ri...

Abstract

The invention provides a testing machine for adjusting the durability of a car steering column. The testing machine comprises a column clamping apparatus and is configured with a data acquisition and processing system. The column clamping apparatus enables a tested steering column to be mounted according to a real car position and can clamp the steering columns of different models for testing. An axial adjusting apparatus drives a piston rod of the tested steering column to stretch and retract under the traction of an electric cylinder and simulates axial adjustment of the steering column. A radial adjusting apparatus simulates radial adjustment of the tested steering column under the traction of an elevator. An unlocking apparatus simulates unlocking and locking of a user to the steering column. An axial force sensor, a radial force sensor and an unlocking force sensor record measured force of a test. According to the testing machine, the testing method is convenient and efficient, the tested steering column simulates an actual utilization condition accurately for testing, the testing machine suits related ideas about adjusting durability testing of car steering columns, and the accuracy and the stability of the test results are guaranteed.

Description

technical field [0001] The invention relates to an automobile steering column adjustment durability testing machine. Since the development of the current industry standards in China is relatively lagging behind, no testing standard for the adjustment durability performance of the steering column has been proposed. The invention can comply with various advanced international standards, such as Japanese Mazda standards. MES PA 32100C, Japanese Mitsubishi standard ES-X23023, etc. are used to conduct the adjustment durability performance test of the steering column. This test machine can obtain the measurement data required by various standards. The invention belongs to the technical field of auto parts testing. technical background [0002] The steering column mainly supports and fixes the steering wheel in the car, and transmits the torque applied by the driver through the steering wheel. As people have higher and higher requirements for driving comfort, the position-adjustab...
