U20H commuting buses Based on the Nissan U -series bus based on the initial C -series technology
In 1971, Nissan launched the first generation C series heavy card. Based on the initial C -series technology, Nissan Chai launched the U -series bus for the first time in 1973. At that time, the U series covered two models, namely U20 and U30. These two models are the first generation of Nissan Chai’s buses, which are very representative. But due to time, it is difficult to see this series of models.
The above two pictures are the two cars of the U20 and U30. The two doors on the top are the U30 series, which mainly focuses on the internal bus lines of the urban area and tourist passenger transport. Essence In terms of power configuration, the two cars are also different, but the chassis specifications are exactly the same.
From the configuration table, we can see that there are three sizes in the two U20/30 cars. The short wheelbase versions with a body length of 10.06 meters; medium wheelbase versions with a body length of 10.69 meters; long wheelbase versions with a body length of 11.09 meters. From the perspective of nowadays, the difference between these three models is not large. It can be summarized to the 10-11 meter-level passenger cars, but at that time Nissan Chai still divided the three cars with clear positioning.
This article introduces Nissan Chai U20 series bus from the 1970s (called 4R95 in some areas). The accurate model of this car should be U20H, which is the smallest version of the three models, with a total length of 10.06 meters and a wheelbase of 4.67 meters. From the appearance, the car is full of water stains, and the surrounding area of the window has already appeared very serious rust, and the lower part of the bumper has also produced deformation.
The windshield is designed for splitting, the size is relatively large, and the field of vision is also very good. The wiper uses a pair of brush, but it has been rust and cannot be used. Nissan Chai U20 bus can be folded on the left and right rearview mirrors. The left rearview mirror in the above figure is actually not a deformation shift, but folded in. The turning light on the left and right ends of the front face is designed with a protruding, and the turning light shell fades seriously.
If the wings of the Nissan Chai UD in the middle of the front face have been used on the post -Nissan Chai’s late model, it must be as good as the Nagana’s big eagle label. The lanterns and the periphery of the middle black decorative board use a silver metal edge, which is a bit like sausage mouth. Two lamps are installed on the left and right, and the lamp is covered with a silver trapezoidal border. The U20 engine is rear, so the front face is installed with a sealed black decorative panel.
The bumper should be an additional installed turning light, and the lower half of the bumper is more deformation. Interestingly, the black sheet made of plastic made of plastics on the left and right ends of the bumper. We did not find this design on the original U20 bus. It may be a design added to the later model.
The trailer hook at the bottom of the front face, and the bumper is also covered with a non -slip pedal.
The length of 10.06 meters is also a very popular size now, which can adapt to various road conditions. The positioning of Nissan Chai’s U20H is used for mountain routes. Of course, this size is also very suitable for commuters. The car uses red plus yellow pulling flowers. Until now, the flowers are still clearly visible, and the age is full.
The engine uses a rear form. The airway is installed on the top of the rear rear car, and the heat sink grille is installed on the left half of the rear. The windshield of the rear of the car did not use the overall design, but instead used three pieces of glass to splicing. There are blue stickers on the left half of the glass, and the stickers are written with “Cold RV”, indicating that the car has air conditioners. The taillights on the left and right sides are protruding horizontally.
The tail engine compartment and the switch of the tool compartment use this knob type, which is also a very common design on Japanese bus. However, it may rust after the use time, and the knob in the middle of the switch is difficult to rotate.
Nissan Chai U20H is equipped with a Nissan Chai PD 6 engine, and its sister model U30 is equipped with a larger PE 6 engine. The Nissan Chai PD 6 engine is inline 6 -cylinder direct suction form, with a displacement of 10.3L. The maximum power of the engine can reach 185 horsepower, and it can output a torque of 666N.M at 1200 rpm. This engine is equipped with Nissan C -series trucks in the same period, which belongs to the main model at that time. It is also derived from the PD 6T turbocharged version, with a power of 245 horsepower and a torque of 893N.M.
The bottom of the engine is very serious
The driver’s door is not set up on the left side of the car, but a safety door is set up near the rear part of the car. Japan really attaches great importance to the safety of passenger cars. The vehicle uses a large -size window that can be pushed back and forth. On the body, dense rivets can be seen to fix the skin skin together. Even the rust rivets with different situations are not loose and the skin is not cracking.
Because the size of the vehicle is small, the U20H uses small -sized wheels. The front and rear bridges of the car use six small tonnage bridges with six bolts, which are matched with 16 -inch six -hole steel rings and 8.25 tires outside.
Non -carrying structure, panel spring suspension and independent bridge.
The door is close to the door, and the glass of the upper part of the door is transparent; the lower part is blue and translucent.
The third -level step is used on the car
After entering the cabin, the driving area was first seen. The cockpit of U20 and the Nissan Chai C series heavy trucks were basically the same. The steering wheel specifications should be universal. A big three instrument is installed later, which is quite intuitive from the perspective of the driver.
A gearbox control rod and deductive radio are set on the right side of the driver. All the control buttons are integrated on the small box on the left of the driver, most of which are vertical lever switches.
The functions on the control panel are quite complete. In addition to the control of the vehicle lights, there are also refrigerators control levers, vehicle ventilation system control panels, and air -conditioning engine switch control panels on the panel.
Precautions located on the side of the console
This picture corresponds to the above -mentioned note stickers. The vehicle starts switch is located at the bottom right of the dashboard.

Generally speaking, many of these cars will be used as warehouses, so the seats inside the carriage will be removed. At that time, the passenger cars liked to use the curved roof, which was also to improve the space in the middle of the compartment. The left and right sides of the carriage are air -conditioned air ducts, each air duct with four adjustable air outlets.

In fact, Japanese passenger car manufacturing concepts were very advanced in the 1960s and 1970s, no less than passenger cars in European countries. Moreover, Japan began to pay attention to the safety of buses early, rather than starting reforms after the accident. This is also a place to learn from us. Fortunately, this rare and meaningful Nissan U20H did not enter the scrap plant. Instead, it was seen by the old car collector. In the future, the car will be repaired in appearance to make it look more vivid It will stand in front of all riders with a new attitude.
