One of the main types of products of the Ulyanovsk plant was small delivery trucks and buses based on them. Cars existed in variants with rear-wheel drive (early releases) and with drive on all bridges. From the moment they appeared in the beginning of the 60s to the present day, cars have practically not changed outwardly.
The most global design changes occurred in the early 2000s, when cars began to be equipped with engines with distributed injection and advanced brakes with disc mechanisms in front. Such changes have significantly improved the consumer characteristics of machines. But in general, cars continue to remain extremely simple in design with an extremely utilitarian interior design.
Power units
The design of the UAZ-39625 is typical of all "loaves" (the common nickname for buses and vans UAZ). The design is based on a frame made of steel U-shaped profile. In front of the frame, a power unit is installed, interlocked with the gearbox. Depending on the production period, the gearbox can have four or five speeds. The photo shows the UAZ-39625 early releases.
Currently, the machines are equipped with the only engine option - the four-cylinder petrol ZMZ 4091. Thanks to the electronic fuel injection system, the engine develops power up to 112 forces. According to reviews, the UAZ 39625 with the new engine has become more dynamic and has a good power reserve when driving on the road. Thanks to its high power, the car became capable of accelerating to 125-127 km / h with an average fuel consumption of about 15-16 liters. In difficult road conditions, fuel consumption increases significantly.
Earlier versions were equipped with carbureted four-cylinder engines ZMZ 4104 and UMZ 4218. The engines are structurally very close, but Zavolzhsky has a volume of 2,445 liters and develops 92 forces, while the Ulyanovsk version is 2.89 liters and 98 forces, respectively. In terms of fuel economy, these engines are almost identical and consume an average of 18-19 liters of gasoline. The speed of cars with such power units did not exceed 110 km / h.
Suspension and brakes
The front and rear axles are equipped with dependent suspensions on full leaf springs. Such a suspension provides the car with a high ground clearance of about 210 mm. The stiffness of the suspension is slightly smoothed by telescopic shock absorbers. Both axles are leading; the front axle has swivel joints. The axles are driven by cardan shafts from the transfer case. The transfer case is controlled by a lever located next to the gear lever. Front axle drive plug-in. On earlier models, the bridge was connected with a separate lever in the driver's cab; on modern versions, rotary couplings are used in the hubs of the front wheels. In the photo below, the standard UAZ 39625 in a modern design.
At the rear of the frame there is a hinged bracket with a full-size spare wheel. The early versions of the off-road UAZ 39625 were equipped with drum brakes with a hydraulic drive. Currently, there are disk mechanisms in front, the system itself can be equipped with an anti-lock device, which significantly increases the safety of car operation.
Supply system
Fuel is supplied from two tanks located under the body floor on the frame side members. The capacity of each tank is 43 liters. There is a switch in the cabin that allows you to select the tank from which the fuel will be supplied. At the same time, the level indicator shows the supply of gas in this tank. In the sidewalls of the body there are special openings in which the filler necks of the tanks are located. The design of the fuel system of UAZ vehicles has not changed at all since the start of production. These openings are clearly visible in the photo UAZ 39625, posted below.
Minibus body
An all-metal carriage body with full side glazing is attached to the frame. Access to the passenger compartment is possible only through the side door on the starboard side. There are separate doors for boarding the driver and passenger. Behind the last row of seats there is a small cargo compartment, access to which is possible through a double door at the rear of the body. To heat a sufficiently large compartment, an additional heater is used, connected to the engine cooling system.
In UAZ 39625 there are places to accommodate 9 people. The passenger compartment seats can be easily removed, and the car turns into a full-fledged cargo van. The maximum passport carrying capacity is 900 kg with a total machine weight of 2500 kg.
The latest versions of the UAZ 39625 use a hydraulic power steering and a new speedometer equipped with a liquid crystal display on-board computer.
