Jost tyre inflation system cuts operator costs
Technology provider Jost has released a new plug and play tyre inflation system, which it says is easy to assemble and can reduce costs for truck operators, as well as workshop and off-road time.
Compatible with all common trailers and Jost DCA axles, the system can be quickly fitted and is fast and easy to use, says the firm. The tyre inflation system maintains pressure to raise fuel efficiency, reduce maintenance time and increase safety.
Connected via the vehicle’s air supply through the control unit, an airline is fitted to each axle with air flowing through the axle beam. A pre-assembled stator and rotor is inserted through each wheel spindle providing the auxiliary air supply. The air supply simply connects to the tyre valve with a secure connection maintained by a Jost hub cap.
The system is compatible with all common EBS (electronic braking system) control devices, meaning that no additional components or connections are required for installation on the axle. When the tyre inflation system is used on a semitrailer or trailer, the tyre pressure across all axles is automatically adjusted.
In operation, the system ensures that the tyre pressure is constantly at an optimal level, says Jost. When the system detects decreasing air pressure, the tyre inflation system automatically refills the tyres to the desired level. This reduces tyre wear and provides longer tyre lifespan as well as minimising rolling resistance, which increases fuel efficiency.
Accurate pressure monitoring and inflation also reduces the time required for maintenance checks and reinflation. As a result, fleet operators using the system benefit from reduced operating costs, adds the firm.
The Jost tyre inflation system also increases safety by ensuring correct operating pressures for optimum driving performance and control. In the event of a significant pressure drop, such as a puncture, the system will alert the driver and allow them to pull over when it is safe to do so.
The driver is alerted by warning lamp, installed in a location visible from the side mirrors, such as the headboard or side of the trailer. No light displayed means correct pressure, while a flashing light signals that correct pressure is being maintained and a report is required once the destination has been reached. A constant light signals the driver to stop when it is safe to do so.
For practical use under varying conditions, the system allows for pressure drop due to temperature changes, and as a result the pump will activate depending on requirement.
All Jost DCA rigid axle systems are compatible with the Jost tyre inflation system. The system can also be used with the Jost DCA Airmaster trailer axle, which stores compressed air for the air suspension and brakes in its housing, reducing the weight required for an air tank.
The Jost tyre inflation system has a separate air circuit, which separates the auxiliary inflation system air supply from the Airmaster’s suspension and brake air supply.
