The Jiangxi Kama Business Bus Co. Ltd. (Bonluck Bus) has become the first manufacturer to equip a bus with Allison’s new T390R transmission. Bonluck’s JXK6126 12.6 metre, 47 seat coach benefits from Shift Energy Management (SEM) – a new programme that dynamically manages torque through the transmission to increase durability and offer higher ratings capability. The T390R is the latest in a broad range of Allison transmissions supplied to Bonluck buses and coaches and reflects a long term strategic partnership between the two companies. Allison and Bonluck have cooperated in joint market development activities within China and overseas since Bonluck’s inception in 2007.

World class transmissions support global expansion
Bonluck buses are sold in the domestic market and exported globally where they are particularly popular among Australian fleets. Allison’s T270R transmission was selected initially for the Bonluck JXK6830 school bus, then the cooperation extended to 9.6m buses. Today Allison’s Torqmatic Series transmissions populate the full range of Bonluck buses between 8.3 and 14.5 metres. Among the range, the JXK6110 coach, equipped with the Allison T325R transmission, is widely recognised for its outstanding powertrain performance, high fuel efficiency and environmental credentials. It has been exported to many countries including Australia and New Zealand and is becoming increasingly popular with the passenger transport and tourism markets.
Complementing the adoption of the new T390R by Bonluck is a further new release – the Allison T450R transmission into the new JXK6145 coach – was announced at the recent Asia show (May 6, 2010). The longest (by almost a metre) single unit luxury tour coach in China produces an output of 500 hp and torque of 2100 Nm. “The safety, durability, and passengers comfort provided by Allison’s automatic transmission make it undoubtedly the best choice for the JXK6145 tour coach and intercity bus,” says general manager of Bonluck, Zhang Fucheng.
T390R showcases the latest transmission technologies
The Bonluck JXK6126 with the new T390R transmission produces 380 hp and torque of 1650 Nm; a 200Nm increase in input torque ratings compared to the T375 and T375R models. In addition to Auto-Neutral, Load Based Shift Scheduling (LBSS), and Allison’s prognostic features, the Shift Energy Management (SEM) function makes the best use of LBSS to ensure the optimum operation of the Vehicle Acceleration Control (VAC) and Super Economic Shift Scheduling (SESS). To support a continuing trend for ever increasing engine power and torque, SEM seamlessly modulates the engine torque before the shift is engaged. Clutch energy and thus temperatures are lowered, increasing durability and offering higher ratings capability without increasing the size of the transmission.
“Bonluck and its customers appreciate that Allison is consistently providing high quality transmission and effective aftersales services. At the moment, Allison automatic transmissions are fitted to the majority of our exports to Australia. It shows the profound cooperation between us,” concludes Fucheng.
