Rolling Chassis

<span style="font-weight: 400">Axles can be either driving or non-driving axles. They maintain the position of the wheels relative to each other and to the bus body. A drive axle also transmits driving torque to the wheels. </span> <span style="font-weight: 400">Axles can either rotate with the wheels or they can be fixed to the bus body and have the wheels rotate around them. </span> <span style="font-weight: 400">Bearings constrain motion to the desired motion. </span> <span style="font-weight: 400">This page lists suppliers who deliver axles and bearings for buses and coaches, as well as the latest product news. </span>

<span style="font-weight: 400">The suppliers on this page manufacture brakes and brake systems as well as their constituent components for commercial vehicles such as buses and coaches. This page also features the latest product news and supplier updates. </span>

<span style="font-weight: 400;">The chassis is the rolling chassis minus the powertrain, i.e. the frame on top of which the bus body sits but without the running gear such as the engine, transmission, driveshaft and so on. The suppliers listed on this page manufacture chassis and chassis components. For more specific supplier listings about parts, such as brakes, axles and bearings, steering components and more, navigate further down our products and services directory. </span>

<span style="font-weight: 400">A vehicle’s drivetrain comprises the components that deliver power to the driving wheels, excluding the engine. Depending on whether the buses have a manual or automatic transmission, these components differ. For instance, in a manual-transmission bus the drivetrain will consist of components such as a clutch, gearbox, flywheel etc. while in an automatic transmission it will consist of components such as a torque converter. </span> <span style="font-weight: 400">This page features suppliers who manufacture drivetrains for commercial vehicles such as buses and coaches, or suppliers who manufacture constituent parts. You will also find the latest supplier news and product updates here. </span>

<span style="font-weight: 400">Engines can vary in type depending on the propulsion system used. A diesel bus for example will have an internal combustion engine, while electric buses have electric motors powered by electricity from batteries. Likewise in fuel-cell vehicles, where the electricity from the fuel cells powers an electric motor. </span> <span style="font-weight: 400">This page lists suppliers who manufacture engines, motors and components for buses and coaches. You will find additional resources, such as the latest news and product updates on this page as well.</span>

<span style="font-weight: 400;">The powertrain comprises the drivetrain, engine and associated components. The powertrain together with the chassis makes up the rolling chassis that sits under a bus body. </span> <span style="font-weight: 400;">This is a directory of suppliers who manufacture powertrains or any components parts for buses and coaches. This page also features the latest product updates and supplier news. </span>

<span style="font-weight: 400">Steering systems are made up of components that allow the driver to guide the direction of the vehicle. These components include a steering wheel and steering column. There are a few different mechanisms by which the steering wheel is able to guide the direction of the wheels. Electric and hydraulic power steering divert some of the engine power to assist with the steering function. </span> <span style="font-weight: 400">The suppliers on this page manufacture steering systems or their components. This page also features the latest product news. </span>

<span style="font-weight: 400">This page features suppliers who manufacture suspensions and suspension systems as well as dampers and all the relevant components for these products. Components are things such as air bellows, levelling valves and levelling linkages, shock absorbers and springs. Suspensions are the connection between a vehicle and its wheels to allow relative motion between the two. </span>

<span style="font-weight: 400">This page lists suppliers who manufacture wheels, wheel rims and tyres for buses and commercial vehicles. It also provides supplier news and product updates. </span>
