16 Commercial Vehicles
A division of Tata Motors, TML Drivelines,
is currently the market leader in axles
and transmissions for medium and heavy
commercial vehicles in India. It sought to
introduce a new nine-speed planetary range
gearbox with high and low ranges. In order
to prevent the destructive and potentially
life-threatening effects of the abusive shift
of such transmissions caused by drivers
shifting to low range whilst driving at higher
speed, a solution was needed to block the
range shift when running above a set speed.
IMI Precision Engineering was asked to provide components
for a solution designed in-house by Tata. However, by
applying our commercial vehicle expertise we were able to
propose an integrated solution combining solenoid valve,
actuator, fitting and silencer in a compact single unit.
Controlled by a new electronic control unit specifically designed
by Tata to meet the application requirements, the IMI Precision
Engineering solution offers Tata a robust, life-of-vehicle product,
as well as reducing assembly time, sourcing and logistics costs.
