Automobile steering track rod assembly and ball head pin test device

Abstract

The invention relates to an automobile steering track rod assembly and a ball head pin test device. The test device comprises a machine body, a left support seat, a middle support seat and a right support seat; the left support seat, the middle support seat and the right support seat are disposed on the machine body; and the middle support seat is provided with a mobile support, and an actuator which drives the mobile support to perform a linear reciprocating motion on the middle support seat along the axis of the actuator is connected between the mobile support and the right support seat. A set of test device can be used, the same assembly parts are used, a combination mode of the assembly parts is changed only, corresponding specifications of work fixtures are equipped, and then detection of all current test items of the automobile steering track rod assembly and a ball head pin which comprises an automobile independent suspension ball head pin assembly can be completed, so repeated configuration of multiple sets of equipment is prevented, equipment cost and the occupied land area of laboratory equipment are saved, and using efficiency of equipment is improved.

Description

technical field [0001] The invention relates to an automobile steering pull rod assembly and a ball stud test device. Background technique [0002] At present, the existing automobile steering tie rod assembly and ball stud test device are mainly designed and manufactured with reference to industry standards QC / T 304, QC / T 648 and QC / T 650. Performance tests such as rotational moment, swing moment, maximum axial displacement Quantity, etc. are equipped with a special performance test bench to complete, and the tension and compression fatigue test of the steering rod assembly and the durability test of the ball joint assembly are completed by the reliability test device. With the continuous development of production technology for automobile steering tie rod assemblies and ball stud products, domestic auto manufacturers have more and more stringent quality requirements for automobile steering tie rod assemblies and ball stud products, and the test conditions are becoming more...

AI Technical Summary

Problems solved by technology

Many manufacturers refer to JASO C715-88 "Test Method for Rack and Pinion Steering Ball Stud Bench", SAE J193 "Test Method for Ball Stud Assembly" and the corporate standards of some large foreign companies for automotive steering rods and ball studs. The product test puts forward its own internal control requirements, such as ball joint stiffness measurement, strength measurement, and the durability test of the ball joint assembly. The new requirements for swinging within a certain angle range, and the requirements for rotation, swinging, and loading frequency are inconsistent, the difficulty of the test is increased, and the number of test items is increased. To complete the detection of all items, multiple sets of equipment need to be equipped to fully meet the test conditions, and the investment in equipment is large. , occupy a large area, use efficiency is not high, not very practical
