Control cables

Anropa manufactures a large range of control cables, such as accelerator, speedometer, brake, clutch, bonnet and boot. Control cables are flexible cables used to transmit mechanical force by the movement of an inner cable (most commonly of steel or stainless steel) relative to a hollow outer cable outer casing. The outer casing is generally made up of a helical steel wire, encased in a plastic outer sheath commonly made of PVC which is extruded onto the steel wire.

What Is A Control Cable

The linear movement of the inner cable is most often used to transmit a pulling force. They can exert a push/pull force where the application requires, such as gear shift cables, and throttle cables for heavy duty vehicles and machinery, marine applications or light aircraft . Usually provision is made for adjusting the cable tension using an alloy component such as a screw or barrel adjuster, which lengthens or shortens the cable outer casing relative to a fixed anchor point.

The “end fittings” of the inner cable vary and may either be a small shaped piece of metal, such as a nipples or hooks, or eyes or adjusters which fit into the applicable vehicle component.. The force that these ends will be able to withstand is tested by subjecting each to a “pull test” which exerts a sudden and specific pull pressure onto each “end fitting” at the same time. Anropa tests each cable before it is deemed ready for sale.

Metal Ferrules are crimped onto each end of the outer to prevent cable ends from fraying.
Bowden cables can cease to function smoothly, particularly if water or contaminants get into the outer casing. Anropa insert liners in between the outer and inner casings (where application requires)and fits dust preventing grommets onto the inner to prevent dust and sand entering the outer casing. Where the outer casing is exposed to heat from the engine or manifold extra Heat Protective Material is affixed to the cable at the “hot spot”.

Control Cables For Vehicles

For automotive applications, the control cables are used to complete controlling actions such as:

Accelerator (or throttle) cables - this control cable allows the driver to regulate the amount of power he produces whed he depresses the accelerator pedal. In a carbureted engine, the accelerator cable opens a valve in the carburetor when the accelerator pedal is depressed. In the case of a fuel injected engine, the throttle valve is placed on the entrance of the intake manifold, or housed in the throttle body..

In a gasoline internal combustion engine, the throttle is a valve that directly regulates the amount of air entering the engine, indirectly controlling the charge (fuel + air) burned on each cycle due to the fuel-injector or carburetor maintaining a relatively constant fuel/air ratio.

Usually the throttle valve is controlled with a throttle pedal or lever via an accelerator cable. All Anropa Accelerator cables are subjected to a pull test of 150kg during production process. This is to ensure that the mechanical parts do not pull the cable apart during operation in the vehicle.

Clutch cables operate the clutch from the clutch pedal. In a modern car with a manual transmission the clutch is operated by the left-most pedal using a cable connection from the pedal to the clutch mechanism. Even though the clutch may physically be located very close to the pedal, such remote means of actuation are necessary to eliminate the effect of vibrations and slight engine movement, engine mountings being flexible by design. With a rigid mechanical linkage, smooth engagement would be near-impossible because engine movement inevitably occurs as the drive is "taken up." Smooth operation with a clutch cable is ensured by inserting a liner between inner and outer so that there is even less friction when the cable is operated, or by using a self adjusting mechanism on the cable.

The default state of the clutch is engaged - that is the connection between engine and gearbox is always "on" unless the driver presses the pedal and disengages it. If the engine is running with clutch engaged and the transmission in neutral, the engine spins the input shaft of the transmission, but no power is transmitted to the wheels.

With an automatic transmission, a gear shift or shifter cable is required to actuate the gear shifting lever and the transmission. The transmission shifting is accomplished by a gear shift cable which puts the vehicle in Park, Reverse, Neutral and Drive positions through a lever mounted on the steering column or a gear shifter near the center console.

The gear shift cables tend to be heavy duty and longer than other control cables on the vehicles.

Brake cables In cars, the parking brake, also called hand brake, emergency brake, or e-brake, is a latching brake usually used to keep the vehicle stationary. It is sometimes also used to prevent a vehicle from rolling when the operator needs both feet to operate the clutch and throttle pedals.

Automobile hand brakes usually consist of a cable directly connected to the brake mechanism on one end and to a lever or foot pedal at the driver's position. The mechanism is often a hand-operated lever (hence the hand brake name), on the floor on either side of the driver, or a pull handle located below and near the steering wheel column, or a (foot-operated) pedal located far apart from the other pedals.

The parking brake operates mostly on the rear wheels, which have reduced traction while braking.

When the handbrake is applied, the brake cable passes through an intermediate lever (to increase the force of the pull); this force is then split evenly between the brakes by an equaliser.
Typically, a mechanical lever is added to the existing disc or drum brakes on the car. In drum brakes, the handbrake cable runs directly to a lever on the brake shoes. In disc brakes an additional lever and corkscrew is added to the existing calliper piston. When the handbrake is pulled, the lever forces the corkscrew against the piston.

Control cables can also be used to open the bonnet / hood catch from the bonnet lever inside the vehicle or connect the gear drive to the speedometer clock.

Other types of Control cables are:

Bonnet and boot cables, as well as tailgate (endgate) cables. These can also be used to open the bonnet / hood catch from the bonnet lever inside the vehicle. Tailgate cables are sturdy cables which connect the ends of the tailgate to the vehicle, ensuring the vehicles end gate does not open too far.
