What is the problem of the hydraulic pump shaft on the hydraulic head in the last eight turns?
The impact force coming from the back of the side, such as hitting the rear of a tire when another car is overtaking. In this case, the body may not be visible because the main point of impact is on the rim.The impact force from the inner side of the tyre or extrusion pressure, such as low hit low block, this block card in the front wheel inside inside etc.. In this case, even if the car is moving slowly, the suspension will be "broken" as long as the car is moving". The general is not directly severing this case. The design strength of suspension system is not enough to "definitely minced" this big stone block.
Non normal above example under the stress if the vehicle suspension parts within the tolerance range, the suspension system is not damaged; if the design strength exceeds the suspension parts, light to cause these parts deformation, re fracture.Two, how to avoid the accident caused by broken shaft?Both the Mcpherson suspension and the double wishbone suspension have two opposing vulnerabilities:1. steering rod: the front of the wheel is introduced, the role of the steering rod is to transfer the lateral pulling force of the steering machine, the structure is slim, so it is easy to bend when the larger pressure or impact force is encountered;2., the joint of the lower arm and the knuckle. Because the position should swing (steering), and up and down movement (over rough roads), based on the flexibility needs, this position parts are compact, so it is easy to be damaged by the art, as the joint. When the position is broken, it may be either the knuckle fracture or the broken arm of the bottom arm.
First, what happens when the car breaks the axle?The impact force from the front of the vehicle, such as IIHS25%, bias, collision, tire crash, road edge etc..The impact force from the side of the vehicle or extrusion pressure, such as tire shoulder, guardrail base, squeezed by other car directly into the tire upper; because of this kind of impact force direction of the uncertainty of the initial damaged parts are generally out of control steering rod, steering rod deformation or fracture, the direction of the steering wheel to the lame "under the effect of inertial move on when the suspension system will be damaged. In this case, the speed does not need to be fast, can cause the consequences of broken shaft.
