once in the rapid development of China’s economic construction period – an influential Tatra heavy-duty all-wheel drive truck (1980 1990), and today they returned. 2018, Hebei Changzheng Automobile Manufacturing Co., Ltd. reached an agreement with the Czech Tatra again (earlier on the localization of the Long March by the plant and the Czech Republic its first co-production), in-depth cooperation.
New Energy Intelligence Analysis Net automobile market from another perspective public number, began serialization Hebei Changzheng Automobile Manufacturing Co., Ltd. amp; Czech Tatra joint manufacturing of heavy-duty trucks and military police series manuscript with forward-looking analysis equipment.
1, Tatra heavy-duty all-wheel-drive truck civilian:
was founded in 1850 too pull off the central spine tube full beam + + floating swing axle all-wheel drive system, unlike Mercedes-Benz, MAN, Renault and other world-renowned bearing and drive technology heavy truck adaptation.
in order to China’s reform and opening period, the Czech Tatra lead to vehicle imports to enter the Chinese market. Since the Tatra rich potential retrofit heavy-duty vehicles have carried the unique all-wheel drive capability, using the excellent results in the harsh environment of the construction area, then transferred manufactured by Hebei Changzheng Automobile Co., Ltd. introduced Tatra authorized technology localization .
2, too pull all-wheel chassis heavy military of:
The figure too pull-yl 6×6 all-wheel drive car.
Objectively speaking, Tatra has a central spine beam tube full floating drive shafts + + all-wheel drive system, highlighted in the civilian economy through construction, rather than fuel economy. However, in military applications, Tatra 10×10 Department 4×4,6×6,8×8 even in heavy-duty chassis with good passing ability, load-bearing capacity and great potential modifications, beyond the Mercedes-Benz Unimog.
a classic Tatra heavy-duty trucks, also has a enduring military equipment, troops serving in a number of countries.
The figureTatra 6×6 all-wheel drive heavy-duty chassis models new state retrofit.
evolving Tatra 6×6 heavy high mobility truck, from a simple aptitude by high mobility transition, taking into account the potential for improvement continue to improve.
The picture shows the Czech Army equipment, pull off the Ethernet all-wheel drive car truck 8×8 group modified “Danner” self Wheel 155mm caliber artillery systems.
service in the 1980s, “Donna” on the matter self-propelled artillery systems, mainly used in highway road network developed European regions, blocking the implementation of the Soviet Red Army fire support mission “Armored torrent” total surprise. 155mm caliber artillery conventional multi-level track using traction or carrier-based, relying too pull Czech 8×8 truck type basis, so as to obtain the conversion from non motorized bearing monocoque structure architecture, by integrating and compatibility of the coat.
In fact, the Tatra truck series race car has already completed the military of objective facts.
3, Tatra all-wheel heavy-duty trucks localization:
Czech Tatra all-wheel drive heavy-duty truck retrofit of transport vehicles, early in the reform period of the 1980s to enter the Chinese market to participate in the economic construction. Due to the excellent performance achieved (by and reliability) in the construction of major projects complex road border region, Hebei Changzheng Automobile Manufacturing Co., Ltd. began to introduce and localization of Tatra prelude. However, through a series of complex processes, manufactured by Hebei Changzheng Automobile Manufacturing Co., Ltd. of Tatra cars ended the localization process.
2018, in Hebei Changzheng Automobile Manufacturing Co., Ltd., opened again Tatra heavy-duty all-wheel drive chassis full-line prelude localization. After the Czech Tatra factory in a series of talks confirmed, Hebei Changzheng Automobile Manufacturing Co. localization of the latest state of the art of Tatra car family.
Long Xingtai in Hebei assembly plant, with many showing “bright spot” of the panels. Of particular note is that the current Hebei Changzheng Automobile Manufacturing Co. All Tatra chassis modifications 4×4,6×6,8×8 of the Czech Army and other countries in the military version of the complete structureFull agreement.
The picture shows the pull-off before too Long Automotive Manufacturing Co. Hebei different state of the drive axle old and new technologies “outside eight” closeup contrast ratio.
The green arrow: load camber new technology for 0-1deg;
blue arrow: the old state of the art, in order to turn the drive wheel is a front traction by the chassis of 8×8 (the first 2 bridge) angle is set to “outside the eight” state (3.5deg;)
mentioned in the foregoing, “change on” state during vehicle imports to too pull 6×6 dump truck and other changes car, drive axle steering angle of the first and the second and third drive axle wheel have adopted “outside the eight” tune state. Dip tube with a central spine beam and all-wheel drive technology set, maximize fit the needs of the construction of infrastructure in areas of scarcity. Although even the inclination overload state of Tatra driving wheel in a “normal 0-1deg;” in full attitude, but “outside the eight” stance lightly loaded condition, directly enhance the outside of the tire tread wear, the cost of upgrade imported with the same period Steyr, Mercedes and other main economic difference between the more heavy-duty trucks.
Now, Hebei Changzheng Automobile Manufacturing Co. localization of Tatra chassis series, will be divided into different states of tune inclination factory settings models, and will be introduced later in detail.
Long plant is located in the assembly workshop Xingtai being 4×4 multipacks too pull models. As shown above, this 4×4 too pull a “no-load eight outer (0-1deg;)” single-tire front twin all settings. Reportedly, these 4×4 Tatra all-wheel drive chassis will be used for heavy-duty vehicles into the room.
The picture shows the standby state
, the central spine by a tubular beam steering, front drive axle + torsion bar spring, rear axle and suspension + airbag splitter configured the Tatra 4×4 “chassis” close-up state of the art.
The picture shows the standby state
, the central spine by a tubular beam, before the first and second driving axle + leaf spring, 3,4 rear axle suspension airbag + Tatra 8×8 “chassis” close-up frame and the state of the art splitter configuration.
Now march localization 4×4,6×6,8×8 Hebei produced too pull the chassis, and the Czech Republic too pull all the same chassis to apply the latest state of the art (12 generations).
Long Automobile Co., Ltd. Hebei current collection early localization too pull (8 generation) + central longitudinal spine tubular beam splitter axle systems and . The picture shows the earlier too pull adapted splitter.
12 adapted generation technology too pull the full drive chassis splitter, or through a transmission drive shaft and associated with the engine. 12 is adapted such setting generation technology too pull the chassis and the integrated transmission splitter split technique of substitution.
Long Hebei early localization too pull the chassis, suspension and also into the airbag spring steel suspension state of the two techniques. Use according to distinguish overloaded dominant performance models 8×8 multiple spring steel plate as a rear suspension vehicle.
But, the old state is made too pull chassis plate spring 13 is set, the new state made too pull chassis plate spring 12 is set.
The picture shows the old state of the localization too pull drive axle differential stage for close-up of the noise detecting. In theory, drive axle Tatra have the ability modular integration. In the central spine tube beam splitter is in the extended group 1 or group 2 forward steering drive axle, extend rearwardly, four or even 5 sets of drive axle steering drive. Extend from 4×4 to 10×10 chassis throughout differentials played an important role.
Monitoring by simulating different loads and different speed differential noise can “push against” localization rear differential gear plate, bevel gear, bearing and lock engage precision degree.
The picture shows the localization of the old state before turning off the pull too close-up drive axle drive axle.
I have something to say:
It is undeniable that, in the 1980s – 2000’s full speed of China’s economic construction period, from the Czech Republic Tatra series in time to fill in the non-paved road heavy haul equipmentPreparation of neutral, heavy trucks and even become an integral part of the PLA “perfect” models.
In the foreign military, pull off the Ethernet all-wheel drive-based heavy chassis, a variety of military equipment system expansion. The central spine tube and the adjustable beam airbag + + all-wheel drive suspension set, ideally suited to the needs of protection for the main police security needs heavy equipment.
later, the new network will focus on energy intelligence analysis Manufacturing Co. localization of Tatra all-wheel drive heavy-duty chassis 4×4 modified state of Hebei Changzheng Automobile detailed interpretation and analysis in order to focus on police safety equipment suitability.
