Rolling Chassis

The rolling chassis is the chassis coupled with the powertrain. The powertrain consists of the engine and drivetrain, while the chassis is the load-bearing frame that supports the bus body. Other parts that comprise the rolling chassis are things such as the wheels and the transmission. Essentially, the rolling chassis is made up of all essential parts of a bus without the body. This page will give you a listing of suppliers who manufacture either the entire rolling chassis or constituent parts. You can get more specific supplier results by navigating further in our products and services directory.

      Axles & Bearings

      <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>

    • Bus Brakes & Components

      Bus Brakes & Components

      <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>

    • Chassis & Chassis Components

      Chassis & Chassis Components

      <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>

    • Drivetrain

      Drivetrain

      <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>

    • Engine & Components

      Engine & Components

      <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>

    • Powertrain

      Powertrain

      <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>

    • Steering Components

      Steering Components

      <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>
