EQ6810CTBEV4 | Dongfeng electric bus
The Dongfeng EQ6810CTBEV4 pure electric city bus features a monocoque chassis and is equipped with a TZ260XSXL540700A permanent magnet synchronous motor manufactured by Hubei Green Mobility Precision Electric Drive System Co., Ltd., and a 151.7kWh battery manufactured by CATL (Contemporary Amperex Technology Co., Limited). The motor is rear-mounted, and it has a 4×2 rear-wheel drive configuration.
The EQ6810CTBEV4 pure electric city bus utilizes a new type of permanent magnet synchronous motor, characterized by high efficiency and high torque. The vehicle design was optimized based on urban operating conditions, fully leveraging the characteristics of the motor system, resulting in stable power output and leading energy consumption levels in China. Independently designed and developed since June 2019, the first batch of products was delivered to customers in November 2019, suitable for operation in large and medium-sized cities.
As part of EMAC, DuraMac provides a complete powertrain that integrates with DCEC engine, Fast-Eaton clutch, FAST-CAT transmission, Dongfeng-DANA axle, and Komman air suspension. While the electrification of automobiles is a certain future, DuraMac also gets involved with EV powertrain systems.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from troubleshooting to overhaul technical support.

DCEC ISL8.9 series automotive engine is four-strokes engine with 102 mm bore and 120 mm stroke, Equipped with Bosch (or BYC or Weifu) pump. engine comes with turbocharger and Air- Air intercooler. The prime power range is from 269 HP to 394 HP. The F6A Series Automated Transmission uses the FAST automatic transmission, has six front gears, the transmission ratio step arrangement is reasonable, has very outstanding fuel economy. Adopt hydraulic automatic transmission. The F6A Series Automated Transmission has six gears, each with a different reduction ratio. Electric wheel dump trucks use electricity as a power source, completely abandoning traditional fuel engines. This change enables the vehicle to achieve true “zero emissions” during operation, without the emission of pollutants such as carbon monoxide, nitrogen oxides, and particulate matter in the exhaust gas, greatly reducing the pollution to the atmospheric environment. Applying the advanced technology of DANA with high efficiency, fuel economy, strong load torque, low noise,high reliability, lower procurement cost, low repair cost and lower maintenance cost. The Datong HW25712XSJ Heavy Manual No-Sync Gearbox has a torque of 2500 N.m, a gear ratio range of 14.941-1, an oil capacity of 13 L (13.5 L when equipped with a power take-off), an overall length of 993 mm, and a weight of 428 kg. The DFZ5258JSQSZ6D truck crane is a powerful and versatile vehicle designed for efficient lifting and transportation tasks. Equipped with a YCS06300-61 engine and a Shaanxi Auto Fast gear : 10JS120TA high-low gear with synchronizer、PTO gearbox, it provides strong and stable power for demanding operations.DuraMac
