PAZ-672 small category bus equipment is a typical representative of transport from the times of the USSR for urban and local transportation with a small passenger flow. The main advantage of such a machine is considered to be a high rate of mobility, maneuverability and cross-country ability on city streets and along the highway. The bus in question is one of the most popular samples in a wide range from the designers of the Pavlovsk plant. Serial production of the model was carried out from 1967 to 1989. During this time, about 300 thousand copies were produced, which were distinguished by ease of operation and maintenance, low fuel consumption, reasonable price (compared to any other analogues).

History of Creation

The mass production of the PAZ-672 modification was preceded by a long period of improvements. Designers began to work on the development of the model back in 1957. As a result, the vehicle was equipped with a steering mechanism with a hydraulic booster, a V-shaped motor. After the release of the first production model in 1959, work on the bugs continued.

After that, PAZ-672 appeared, which mostly became a copymodifications 652-B. Among the differences from the progenitor, a new body frame, enlarged windows and a reduced weight of the structure can be noted. The real starting version was born in 1967.

Technical characteristics of the bus PAZ-672

The model under consideration has a wagon layout, equipped with 23 passenger seats with a maximum capacity of up to 60 people. Small windows with vents are offset by an additional hatch at the base of the sloping roof. The narrow doors are pneumatically operated and designed to allow one passenger to pass through at a time. The driver's cab is separated by a curtain or light plywood partition. The ceiling is equipped with six ventilation flaps.

Description

Modification PAZ-672 adopted many parameters from GAZ 52A:

• 115 hp four-stroke OHV powertrain.
• Engine type - carburetor with a displacement of 4.25 l.
• Transmission is a four-speed transmission with a leading front axle.
• Clutch is a hydraulically actuated single disc dry assembly.
• Suspension - spring block with liquid telescopic shock absorbers, which reliably dampen vibrations during movement and guarantee good grip of the wheels with the road surface.
• Brakes - split drum unit with vacuum booster and hydraulics.
• The carburetor is located in the front overhang of the equipment, which led to the displacement of the first door.

Other options

The following arecharacteristics of the equipment in question in numbers, including the dimensions of the PAZ-672:

• Length/width/height - 7, 15/2, 44/2, 95 m.
• Wheel base - 3.6 m.
• Front/rear track – 1, 94/1, 69 m.
• Clearance - 32 cm.
• Ceiling height - 1.88 m.
• Total weight - 8.0 tons.
• Number of seats (common/seating) – 45/23.
• The maximum speed is 80 km/h.
• Fuel consumption with maximum load - 20.5 l / 100 km.

Modernization

At the end of 1982, a modernized series of the PAZ-672 bus was released, which had an additional index "M". The main differences of the car were the safe design of the seats, increased power of the power unit, enhanced thermal and noise insulation. As a result of refinement, the number of skylights was reduced from six to four. This somewhat worsened the ventilation characteristics of the cabin. In the new variation, in addition to the standard headlights, two fog light elements were provided, as well as enlarged turn indicators.

After 1982, the PAZ-672 bus with one door was created. It was equipped with a passenger entrance in the area of \u200b\u200bthe rear cabin compartment. Often such machines were operated as special service vehicles. This modification in some regions can actually be found today, despite the fact that its release was suspended in 1989.

Main Models

Pavlovsk Automobile Plant for 22 years of serial production of PAZ-672 equipment technical characteristicschanged according to the demand and preferences of the relevant market.

Most popular mods:

• Series 672-A. This copy is equipped with a sliding lightweight roof. It has one door in the front with manual opening without glazing. The first version was assembled back in 1967, mass production was canceled due to unprofitability.
• Model 672-VU. The machine is a version on a self-propelled chassis, which was imported to Liberty Island (Cuba) from 1971 to 1989. Feature - multi-purpose bodywork. The number of units produced is from 2500 pieces per year.
• PAZ-672 G is oriented to mountainous terrain, equipped with two fuel tanks of 105 liters each. The equipment of the equipment provides for belt equipment for all seats, hydraulic power steering, seat belts on all seats. In the exterior of the car, the glazed ceiling slope was changed, and improved brakes appeared. In addition - an angle stop for stopping on slopes up to 25 degrees, the ability to open the trunk from the inside.

Other modifications

Among other versions of the PAZ-672 bus, the following variations are noted:

• A single model with index D, which provides for the use of a power unit from Minsk manufacturers. A version was produced in the 80s of the last century. The prototypes only confirmed the inexpediency of manufacturing such modifications.
• PAZ-672 K. This is a testing machine, the development of which has been carried out since the mid-70s. The equipment received an updated exterior with an angular body, double-leaf doors, a front part similar to modifications 665 and 3230. In fact, innovative changes did not have a foundation supported by practical and operational results.
• Model 672 C is designed for the northern regions, equipped with an independent mounting system, double-glazed windows, a one-piece roof without side windows. In addition, reliable seals for doors and hatches are provided in the design of the bus. Inside the PAZ-672 cabin of this type, even in the most severe frost, a comfortable microclimate was maintained. Modifications were produced in red or orange colors.
• Version 672 T is an updated luxury coach with comfortable high seats and manual door opening. The bus was produced in small series, its development has been carried out since 1960.

Special transport

On the basis of the all-wheel drive PAZ-672 TL, a research tensometric laboratory was constructed. The novelty differed from the standard bus in the presence of a solid solid roof and two internal partitions in the body. Only 10 copies were produced (1980) by order for the Olympics.

A few more samples can be noted:

• 672 Y is an export version for temperate regions.
• 672 Yu - for tropical countries. The whole roof has lost glass inclusions, the main color scheme is white with multi-colored lines.
• Based on PAZ-672, a bus with a fulldrive 3201. The main differences are the absence of a rear door, a higher landing, the number of seats has increased to 26.
• Refrigerated trucks for transportation of perishable goods (modification 3742). Serial production of machines was started in 1981. Later, the release was transferred to the Baku plant for the manufacture of special equipment. First, ready-made cars for the installation of refrigeration units were delivered to Baku, then only some basic spare parts for PAZ-672.
• Mobile television station (model 3916). The working equipment was provided by the Kirovograd plant of radio engineering products. The complex included four television cameras, a pair of video recorders, a radio channel, director's and sound consoles. Only 16 such copies were produced.
• VgArZ is a mobile blood sampling system manufactured at a car assembly plant in Voroshilovgrad.
• The KT-201 version had a frame and engine from PAZ-672, and was manufactured in Arzamas. The main purpose is the provision of funeral services. A hatch is provided for the coffin in the rear wall of the car, the seats are placed along the sides of the bus. The outer part of the equipment had a distinctive sign in the form of a wide black stripe.

Operation

The first experimental PAZ-672 buses appeared in 1960. The car completely replaced its predecessor under the index 652 only eight years later. During this period, several experimental modifications were created, the differences between which are discussed above. The basic bus model was produced until 1989. The universal design made it possible to operate the machine in various climatic regions. For 20 years of mass production, the PAZ-672 has been supplied to all post-Soviet states, as well as countries in Asia, Eastern Europe, Africa, and Latin America.

The main scope of the considered equipment was official and custom transportation. She, along with KAVZs and GAZs, was in the car garages of many enterprises and organizations. These buses were used on suburban and intercity routes. Despite the fact that more than a quarter of a century has passed since the end of serial production, 672 models can still be found in the post-Soviet space in work, although quite rarely.

Competitors

The main rivals of this car in Soviet times were the following buses:

1. KAvZ-685 refers to small general-purpose modifications, produced on the basis of the GAZ truck chassis since 1971
2. LiAZ is a spacious city bus, distinguished by reliability and worthy performance.
3. "Ikarus". The famous Hungarian bus was supplied to the USSR in several modifications. The traditional color is canary or red and white.

At the end of the review

It is worth noting that PAZ-672 with one door was popular. After 1982, the letter "M" appeared in their designation. Many of these models, found in the 80s and 90s of the last century, were converted two-door versions. In 1989, the Pavlovsk plant stopped producingmachines in question. Without stopping the main container, the plant switched to the production of completely new modifications under the index 3205.
