A Brief Introduction Of Control Cable
Introduce the control cable of several categories: first
, push cable (Pull-Push Cable), cable core in a natural state, without axial force; in working condition, can withstand axial tension and thrust, but can not pass rotating load. In automotive engineering, the push cable is mainly used for remote control (indirect control) mechanical transmission control systems, such as flat head truck in the rear-engined passenger cars and motor vehicles, variable speed transmission from the driver's body, called the election file push push cable and shift cable. Rod control mechanism with the traditional comparison used to promote cable has the following advantages:
Layout flexibility. Can be used to promote the flexible cable arrangement, especially for the low number of chassis, engine, rear set or large, medium-sized passenger car, the engine room barriers, difficult layout with a bar mechanism, and the manufacturing and maintenance costs. Has a structure used to promote the advantages of cable.
Simplifies the design of variable speed control mechanism. The drivers hand to simplify the transmission into three parts: the manipulator cab; two push cable; and transmission matching converter. By the three parts of a complete mechanical speed control system, and these three parts can be designed independently, simplifying the design work.
The manipulator push cable in the cab of the specific installation location is not accurate positioning constraints, even if the changes about the installation location has little effect on the entire system, unlike bar mechanism as the need to redesign the root of each rod length, intensity and installation node and so on.
Eliminate the frequent adjustment rod and joint loosening the noise, so speed the process in the smooth, quiet (no noise) to conduct operations, greatly reduces cab noise, improve vehicle comfort.
Eliminated by the cab mobile (relative to the chassis of the movement) led to transmission gear teeth and fight tooth off. Because the push cable casing fixed to the manipulator, the cab mobile will not lead to cable core and the casing of the relative displacement converter that will not lead to abnormal movements and improve the stability of the vehicle's speed, and reduced driving dangerous.
Installation of low cost, fully sealed design without lubrication, low maintenance cost.
Then look for the cable (Pull Only Cable) cable core can only carry axial tension, and tension has been in a state of the work process, mainly for axial motion, not passed rotating load. When installed, usually in one or two control terminals loaded a certain elastic force to ensure that the natural reduction of cable. In the cable car engineering application are: speed drive control cable (the throttle cable); choke control cable; clutch cable; hand brake wire rope assemblies; foot brake cable; idle throttle control cable; engine cover lock and flame control cable and so on.
Finally the point of spark plugs. In actual operation, in addition to the right choice for your car's spark plugs, there are some measures that can effectively control all of the contamination, give full play to the role of spark plugs. Such as to avoid prolonged low-speed, low load operation; to reduce idle running time, more and more car experts believe that the vehicle damage vehicle idling; to avoid high-speed, overload running, if not buy a cell phone with the same transfer, it is best not to drag racing ; fuel to maintain a certain purity, look for the brand of oil is critical; avoid hard acceleration, rapid deceleration running other bad driving habits. The only way to effectively control the contamination of various spark plug to extend the service life of spark plugs improve engine efficiency.
