6798H Coach

6798H series coach is an extraordinary one among Zhongtong mid-size buses. Focusing on technological innovation and customer demand, Zhongtong has accomplished dozens of optimizations in buses' structure and performance, and made breakthroughs in security, energy conservation, space, and some details. 6798H is now gradually becoming a new paragon on the mid-size vehicle market.

Main Features
Appearance Upgrade

6798H coach shows splendid and cool appearance in the front part. When designing the headlights, Zhongtong refer to the design of car, to integrate the headlights into the chrome plated middle panel. The characters "ZHONGTONG" can be lightened for higher degree of recognition. The special boomerang-shaped rear lamps and LED dot matrix lights make the bus look modern and fashionable. The multi-mirror blind-free rearview mirror is adopted to enhance diver's vision.

Higher Reliability
The pipe and line layouts are optimized to improve the coach's reliability and to make maintenance easier. The underslung frame is punched as a whole to add to the system's reliability and strength.
The dehydrator and degreaser are installed at both ends of the pipeline system to provide clean compressed air and to extend the service life of the brake system.

Better Practicability
A maintenance door is installed at the front bus part for the convenience of checking the pipeline and adjusting the headlights. The brightness of headlights and inner dome lights is improved to guarantee drivers' and passengers' safety when driving at night. The clutch operating system is designed with automatic gap adjusting function to automatically adjust the gap and extend the service life of the clutch.

Greater Comfortableness
We have optimized the suspension system by increasing the roll stiffness, for higher lateral stability and controllability, as well as wider applications. The seat is user-friendly, with the back curve designed to be in line with the ergonomic principle. The interior space is optimized to widen the space for passenger and pass way. The multi-layer body helps to reduce the noises from both inside and outside.

6935H Coach

The Sparkling series coach is our new product designed for medium and short distance passenger transport and tourism. Basing on some mature products on the market, it is designed to be more human-friendly. It shows a much better versatility and lower cost. For the bus body, the flat floor makes it easier to cleaned and for passengers to walk on; the overhead air intake system helps to improve the air intake quality of the engine and to make it more economical. For the driver operating part, to add to drivers' comfort and convenience, we have made the shift lever to be separated from the engine cover, and lengthening the lever to increase the arm force.


Supported by CATIA, ALIAS and other engineering software, as well as the CAE finite element analysis technique, Sparking coach gains a reliable and reasonable structure, which makes it highly safe. Compared with other similar coaches, its drag coefficient is 5% smaller. The sunken engine is installed under the seats of last several rows to make full use of the interior bus space. The combination of reasonably-arranged chassis, intelligent temperature control system, as well as Zhongtong simulation analysis system, which is competent in simulating the running conditions of vehicles under various typical traffic situations, Sparking series coach can save 5-10% of fuel for users. In addition to the air suspension with six airbags and the bidirectional telescopic shock absorber, there are details of meticulous designs and energy-saving techniques everywhere in the bus, such as the extremely long-life LED lights for all of the bus lights except the high beam. The service life of LED is up to 8 to 10 years, with the energy consumption only 20% of that of ordinary fluorescents.
