Headquartered in Montichiari, near Brescia (Italy), BRIST is a key supplier of axles, independent suspension and gearboxes for electric vehicles (here’s an interview with the company’s management dating back to a couple of years ago). Mainly active in the bus sector, BRIST is working more and more in the LCV and even heavy-duty truck industry, providing its innovative solutions conceived for electric vehicles.

BRIST’s independent drive and semi-trailing suspension

In the field of LCVs with vehicle length between 4 and 6 meters, BRIST has developed a whole range of products. The company’s independent drive suspension is featured by double wishbone suspension and stands out for its improved dynamic and kinematic behaviour. Axle load is up to 3 ton, with steering maximum angle of 45 degrees. Both driven and non-driven configuration are feasible keeping same structural components, which combined to steer function perfectly fits for Autonomous Shuttle platform either for goods and people transportation allowing:

  • Bidirectional movement
  • Very small turning radius
  • Modularity in axle configuration (4×2 or 4×4) keeping same axle layout
  • Flexibility in e-motor selection to be coupled with single or 2-Speed transmission

Independent semi-trailing suspension has got the same axle load of 3 tons and is suitable for wide and low cargo floor dimension. Also in this case, both driven and non-driven configuration are feasible keeping same axle layout. Thanks to its compactness, BRIST semi-trailing suspension is suitable for delivery vans (goods transportation) allowing very wide and low cargo floor level with additional free space between the wheel arch for bigger loading space. Axle is provided for both mechanical and pneumatic suspension (where levelling function is required).

BRIST portfolio also offers transmission solution for light commercial vehicles:

  • single-speed transmission featured by different ratios available to comply with different speed requirements. The transmission is conceived for vehicles with GVW up to 5.5 tons. Technically speaking, peak input torque is 340 Nm, while the transmission peak power reaches 125 kW.
  • 2-speed transmission for better vehicle performances in higher efficiency. The transmission is conceived for vehicles with GVW up to 8 tons. Technically speaking, peak input torque is 460 Nm, while the transmission peak power reaches 200 kW.
