Bus small class PAZ-32054: history and description

Bus small class PAZ-32054 is one of the thirty versions of the basic model of the mass bus Russia 90s and 2000s PAZ-3205.A distinctive feature is apparent two-door layout of the cabin, but if you look deeper, we identified a number of technical innovations.After the gradual modernization of the vehicle has become more reliable, increased consumer characteristics and lifespan.

humble worker

In December 1989, at the Pavlovsk plant them.AAZhdanov (Nizhny Novgorod region, Pavlov) was launched at a series of "life" has become a legendary model of suburban and urban bus of small class PAZ-3205.They can be found in every city in the country, because this four-worker became the most mass bus, manufactured in the country.Total has developed more than 30 versions of this model, ten of which are produced commercially.One of them is the bus PAZ-32054.

Despite the modest appearance, nimble "Lasik" has proved its usefulness, and on crowded city streets cars, and suburban routes with low passenger traffic, and as a special transport organizations, enterprises, educational institutions in various fields.A two automatic doors PAZ-32054 is much more convenient one.

bit of history 25 years ago nobody would believe that only just embarked on the conveyor PAZ-3205 is prepared not only bright life, but also an opportunity to break the record for longevity of its predecessor - PAZ-672.The bus was not a consequence of the planned upgrade of the lineup.On the contrary, it was the result of failure of the production of more advanced model PAZ-3203, parts of which have not been able to put related organizations.The designers of the plant found a compromise solution - have joined a new body with the old chassis, of course, conducted over the last all possible improvements.

first prototype of PAZ-3205 was assembled in the summer of 1979, only a decade later entered into a series.Although a significant percentage of unification and external similarity with buses series 3203, 3205 different interior layout and had a number of structural differences in the body.A year later, the predecessor of modern factory workers presented PAZ-32054 - two-door modification of PAZ-32051.

Design features

basic chassis was common to all the large family of new "keyway."One of the most important features is the original pneumohydraulic braking system, will help eradicate one of the major ills of PAZ-672 - lack of effectiveness of the service brakes with gidrovakuumnym drive.Changed and steering - the use of "ball-screw" with built-in booster (on MAZ-5336) made it possible to reduce by 60% the number of hoses, increasing the reliability of the unit.

not gone unnoticed and suspension: spring narrowing gauge possible to reduce the turning radius, and elongated front springs, together with the installation of corrective springs in the rear suspension increased smoothness.The body design of most of the performances were of the same type.This applies to the PAZ-32054, a photo of which, if we close our eyes to the door further, as two drops of water similar to the pictures of PAZ-3205.In 2013, after a slight restyling headlight design has changed - they became rectangular.

Specifications of this modification is significantly improved in comparison with the base model.Body got two doors in the middle and at the end of the cabin.Unlike standard single-door variants, this innovation has greatly facilitated the landing-disembarkation of passengers and improve vehicle safety: in the event of an accident or tehpolomok operatively people can be evacuated from the cabin.Due to the appearance of additional windows changed the location of the seats, and the number of seats declined slightly.

Powerplant

Initially, under the hood, it was decided to install two versions of engines - petrol and diesel.If gasoline (ZMZ production and MSW) is not proven, then diesel unforeseen problems.As the diesel units were considered domestic gas-542 and Japanese Hino W04CT.The first diesel "keyway" went on trial in 1987, but due to difficulties layout "gazovskih" motor fizzled out almost immediately, and doroguschy Japanese diesel put in PAZ-32054 only for the order from the beginning of the 90s.

is also developing its drive on LPG.Back in 1987, have been prepared terms of reference and technical documentation on the bus with a propane gas equipment, prototypes of which were built in 1987-1989.Finishing work on these machines were made in conjunction with the designers of the plant PAZ, GAZ and ZMZ.

Now PAZ-32054 (specifications are listed below) has two types of performance:

• proper modification 32054 with petrol engines ZMZ production;
• 32054-07 gasoline MSW.

The table shows the characteristics of each model:

PAZ-32054: Features and Benefits

• Body type: integral, wagon-type, all-metal.
• Number of seats: seating 18-23, 38-43 overall.
• width / length / height: 2530/7000 / 2880-2940 mm.
• suspension are reliable on any roads.
• Improved consumer characteristics.
• High maintainability.

Conclusion

simple, easy to repair design, compact size, cost, high return and low (relative to competitors) cost allowed "keyway" win the hearts of the operating organization and passengers.
