Abstract
The utility model relates to an eccentric loading device for a fatigue test of a steering knuckle, belonging to the field of an automotive testing device. By adopting the mechanical vibration principle, a wider load range can be provided, and a load can be controlled accurately. A steering knuckle clamping device is provided with a swinging body I and a swinging body II, the swinging body I is provided with an eccentric wheel, and a motor shaft of a motor is inserted in a shaft slot of an eccentric shaft. A novel platform for the fatigue test of the steering knuckle is established, the structure, materials, manufacturing processes and the like of the steering knuckle can be verified and evaluated, and the basis is provided for the design of the steering knuckle.
Description
Technical field
The utility model belongs to automobile test device field.
Background technology
Steering knuckle is the important security personnel's part in the automobile steering system, must carry out the checking of fatigue behaviour to it in steering exploitation and existing production, so that determine the rationality of its structure, material, manufacturing process.
At home and abroad in the automobile industry, particularly the ensure public security torture test of part of automobile important spare part is approved and is popularized, but the steering knuckle torture test does not gain universal acceptance at home as yet.Only in the torture test of steering assembly, steering knuckle is investigated and estimated at present, but fatigue lifetime and reliability to steering knuckle that this kind method can't system are assessed fully.
Summary of the invention
The purpose of this utility model is by adopting principle of mechanical vibration, the precisely eccentric charger of the steering knuckle torture test of control load size of broad load range and energy can being provided.
Pendulum mass I and pendulum mass II are installed on the steering knuckle clamp device of the present utility model, on the pendulum mass I eccentric wheel are installed, the motor shaft of motor is inserted in the interior axial trough of eccentric wheel.
The utility model is set up a kind of novel steering knuckle torture test platform, the structure of steering knuckle, material, manufacturing process etc. is verified, is estimated, for the design of steering knuckle provides foundation.
Consider the structural similarity of steering knuckle, the steering knuckle stress form on the different automobile types is basic identical and feature such as carrying wide ranges etc., need to consider to adopt a kind of special resonance loading method satisfy this testing requirements.And the method that off-centre loads can provide precisely control load size of broad load range and energy by adopting principle of mechanical vibration, and this kind load mode can effectively imitate the loading characteristic of steering knuckle on automobile in addition.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model eccentric wheel structure synoptic diagram.
Embodiment
Pendulum mass I 1 and pendulum mass II 5 are installed on the steering knuckle clamp device 6 of the present utility model, eccentric wheel 4 is installed on pendulum mass I 1, the motor shaft 3 of motor 2 is inserted in 7 li of axial troughs in the eccentric wheel 4.
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The objective of the invention is provides bending load for the steering knuckle bench test.Motor is connected with eccentric wheel by rotation axis, the eccentric wheel synoptic diagram is seen shown in Figure 2, drive shaft cartridge has in the axle sleeve of groove in the middle of fitting over eccentric wheel, leave the gap between axle sleeve and the eccentric wheel, by the distance between set screw adjustment rotation axis and the eccentric wheel center, can adjust to guarantee oscillating load.
The synoptic diagram of steering knuckle testing table is seen shown in Figure 1, and motor drives eccentric wheel by transmission shaft and rotates, because center transmission shaft and eccentric wheel center are not point-blank, eccentric wheel produced centrifugal action when motor rotated, and drives the swing of pendulum mass I.Be " U " shape structure between pendulum mass I, pendulum mass II, the steering knuckle clamping system, drive the swing of pendulum mass II during the swing of pendulum mass I, produce the bending load effect at the investigation position of steering knuckle, to reach the purpose of torture test.
Claims (1)
