In this market revolution, as an established company with a history of more than 100 years and a high degree of social responsibility, Chang'an Bus once again played the role of leading the development of the industry. On October 29, 2013, Chang'an Bus Manufacturing Co., Ltd. successfully held its first annual new “Take a Profit and Win the Future†public event in Changzhou International Hotel in Dingzhou International Hotel. The event invited dozens of people to the Northeast The main dealers and user representatives gathered together with the leaders of Changan Bus Manufacturing Co., Ltd. to deepen their understanding and recognition of the Chang’an bus market development concept, and also jointly visited a new generation of bus products that have been tested and used in Chang’an buses.
Changwu Bus Assistant General Manager and Coach Business Department Director Guo Wujun said at the meeting that the successful development of a new generation of buses not only shows the ability of Chang'an buses to develop high-end urban buses, but also enhances the level of vehicle and equipment for urban public transport in China. Positive significance. Chang'an Bus also hopes to introduce this new type of high-quality public transport into the market to provide the public with a more convenient and comfortable, spacious and barrier-free mass transit environment. At the same time, it can also attract more people to take green public transport and reduce the number of people. The ratio of private cars travels makes every effort for the country’s atmospheric management. â€
3 major highlights help the birth of the new bus, creating the best choice for the public travel
Afterwards, the technical director of Chang'an bus, Zhenhai Zhen, gave a detailed introduction to the brand new series of buses that will soon be fully introduced to the market. This new series of buses covers 7-10.5 meters, front and rear bus products, Adopted the mature Changan public transport chassis platform + new European style + independent engineering design development model. With regard to the specific changes to Chang'an New Bus, Meng summarized the three directions of use environment, vehicle configuration and customer groups.
With regard to the difference in use environment, the main road conditions of buses are in urban areas. The characteristics of driving are: low speed, frequent parking (traffic lights and stations), frequent brakes, and severe overload. Changan New Bus adopts the design mode of table handbrake and is more spacious. The pedal space is more convenient for the driver to control the driving on the city road.
In terms of configuration differences, such as the very sensitive to the economic fuel consumption of the vehicle, the high requirements on the reliability of the brake and clutch systems, and the relatively high requirements on the carrying capacity of the chassis and the strength of the car body framework, the Changan new bus has also been optimized. Improve the special bus chassis of Chang'an bus. The overall design uses three-dimensional software for analysis, so that the data is accurate; the layout is reasonable and the bus-specific clutch is configured; the suspension system design is optimized, the ride comfort is greatly increased, and the three industries are realized. The chassis has the lowest price in the same configuration and the highest one-to-one advantage in the same price, and the vehicle is equipped with Teljia eddy current retarder and Comet ABS anti-lock brake system to make the vehicle run safer and more environmentally friendly. Equipped with Sanlang centralized lubrication device to reduce the loss of parts, energy saving and environmental protection.
In addition to the above two points, for the most important customer groups, such as multiple orders, large batches, and changes in the requirements and configuration requirements, Chang'an new buses have taken the lead in the country to achieve a 450mm wide channel width, reaching the national first-class standard.
The industry's high-precision equipment Sword quality, strict quality control excellence
Since the second half of 2012, Changan buses have invested more than 20 million yuan in succession to transform passenger car production lines and put in a lot of general-purpose technological equipment. By optimizing the advanced and suitable technological equipment and equipment as well as technological transformation projects, the quality and manufacturing efficiency of Changan passenger cars will be promoted. Chang'an Chang'an Passenger Bus adopts technology to improve its technology, protects quality with science and technology, and promotes development with science and technology.

Roller press forming machines, U/Z roll forming equipment, combined fixtures, self-made oscillating jigs, inner and outer veneer chain conveyor lines, chassis production lines, ABS brake testers... The introduction and application of advanced equipment has promoted Chang’an’s level of craftsmanship has increased rapidly, and at the same time, Chang’an’s control of product quality has been improved.
In recent years, Chang'an bus has become one of the best bus companies in the passenger car market, relying not only on the overall improvement of corporate equipment, but also with the unremitting efforts of employees and the stringent requirements on quality. Chang'an bus application industry's most advanced testing equipment and the most stringent quality control processes ensure the quality and maturity of Changan bus products. In order to prevent unqualified raw materials from entering the factory, Chang'an Bus conducts layer inspections on incoming materials to ensure product quality. In order to test the manufactured products, the Chang'an bus has been subjected to almost rigorous testing, which has ensured the low failure rate and more durable use of the bus. At the same time, the Chang'an bus conducts a reliability road test on the vehicle and simulates the status of the vehicle in complex road operations such as stones and waveforms to understand whether the vehicle's performance can adapt to actual requirements. Coupled with thousands of complete and precise measuring and metering equipments, the entire vehicle is in an effective controlled state in all manufacturing and testing processes, so as to ensure that the operation process is always in a stable state.
Adhere to the "people-oriented: development strategy, bring real fast, safe and comfortable experience
Changan passenger car technical designers will tell the customer about the actual operation conditions when they set the car, such as whether the overload is serious, the mileage of one-way trip, the number of sites, average speed, maximum speed and other information, form a questionnaire, in accordance with The actual use of the customer to match the design to achieve the best matching performance and fuel economy. Through careful investigation of numerous bus companies throughout the country, and careful analysis of chassis matching, fuel consumption, overhaul mileage, and monthly maintenance costs, when bus companies set cars, targeted technologies and processes were optimized or improved to reduce users' operations. Maintenance costs during the period.
In the eyes of the people who have visited Changan's new bus, the internationalized appearance and humanized design can be said to be the deepest impression of Changan's new model bus. The vehicle adopts a low-floor chassis design. The front door is one step away from the ground and the height is 350mm. The middle door is one step away from the ground and the height is 375mm. The interior of the car adopts the armrests for the armrests and the handrails for the passengers to increase the number of catching and using. And unique luggage bag hook design, so that passengers have a relaxed in fatigue. The door of the car is also designed with safety rails on the handrail, which provides great convenience for young and old disabled passengers. In addition, for the problem that passengers feel bored when the existing air-conditioned vehicles do not have air conditioning in the spring and autumn, the new bus windows of Chang’an adopt a new type of concealed guide rails, which can open the windows for ventilation in the spring and autumn, and can also facilitate passengers in Case of emergency. Escape evacuation. It is more suitable for multi-traffic urban lines, which greatly improves the operating efficiency. The design and application of this series of high-tech and humanized facilities have enabled the new bus in Chang’an to achieve a true “rebirth†and become the best tool for the general public to provide fast, safe and comfortable travel.

For the after-sales service personnel of Chang'an Bus, the service guarantee is not only related to the interests of the operating unit, but also more important is a social responsibility for the general public. Chang'an Bus has not only made great efforts in the R&D and production of new buses, but also dispatched experienced staff, together with major suppliers and special service stations, to form a service support team for the after-sales service. The bus service plan was optimized and implemented before the vehicle was officially launched. The bus service team of Chang'an Bus has always been doing its best to serve customers, thinking about what customers think, urging customers to worry about it, and establishing a first-class service team to provide the perfect solution for the development of urban public transport and to solve customer worries.â€
Due to the variety of buses, large batches, and miscellaneous configuration, and with the characteristics of high customer requirements for personalization and professionalism, Chang'an Bus also has its own set of mature pre-sale service solutions. According to the leaders of relevant departments of Changan Coaches, the engineers of Chang'an Bus are not involved in the beginning of vehicle production, but are actively involved in the vehicle technical review conducted by the customer when the vehicle is scheduled. Before the vehicle was built, Chang'an Bus specially discussed and negotiated with the major bus operators in different regions and reached agreement on the supply of accessories and services. At the same time, Chang'an Bus organized many bus company drivers to conduct training on electrics, chassis, driving skills, and maintenance. From the initial stage of product development and design, engineers will participate and also participate in the validation of product technology solutions.
At the same time, for batch bus orders, relevant technical personnel will also decompose and refine the technical agreement, and compile the “Process Inspection Checklist†in conjunction with the quality issues and review information of the same type of vehicles in the market. The process inspectors and finished products Inspectors verify each item on an inspection basis to avoid recurrence of historical problems and ensure the production quality of batch bus orders. Organize finished product inspectors to carry out load test on the first batch of bus orders, pass professional trial roads, simulate different road conditions, and use scientific detection methods to test various performances of the vehicles. Organize technology, process, process inspector, manufacturing department, customer service department, service station technician and customer representative to perform "quartet evaluation, tripartite evaluation" on the chassis assembly, body assembly, and vehicle assembly of the prototype vehicle or the first order vehicle. Demonstration, and form a resolution on the spot, identify and rectify the responsibility department, implement the corrective personnel, and follow up the verification to ensure that the rectification is in place.
Internal tension production, external services first. The reason why Chang'an Bus can consistently achieve outstanding results in the urban bus market is that it has responded positively to the country’s “bus priority†policy, has conducted in-depth studies in large and medium-sized cities and participated in the planning of urban public transport systems, and designed public transport in large and medium-sized cities.
