This shows the interior of the Renault 19. It's easy to see where the main components are located
Renault 19 was developed as a result of the X53 program to create a European middle class car "M1". The project was carried out under the motto "Cars - in life" and took 42 months. Work on the creation of the model began in November 1984, and eight months later, in July 1985, the exterior design of the car was finally approved. Over the next 5 months, the dashboard took shape. In April 1986, interior decoration work was completed. Prior to the launch in a series in France in May 1988, in order to verify and confirm the correctness of the applied technical solutions, prototypes of the model had already run over 7.5 million kilometers on landfills.
Body
Renault 19 design was developed by "Renault design" ("Renault Design") in close collaboration with renowned Italian designer Giorgio Giugiaro. One of the main tasks set before the designers and engineers was to create a car with the best aerodynamics. It was planned to release, first of all, a sports version of the model in order to subsequently use the features of the suspension, brakes and aerodynamics of the body for production models.
Renault 19 with its smooth lines is "thoroughbred" a car whose styling was based on wind tunnel testing. So, the value of the air resistance coefficient C x is 0.31 (C x X A \u003d 0.61) and is one of the strengths of the Renault 19, and the 16-valve Renault 19, thanks to the changes made to the body structure (lower suspension, front and rear spoilers, widened door sills), has improved performance - the value of Cx is 0.30 (C x X A \u003d 0.59). These figures were achieved thanks to a strongly descending hood and a sloping curved windshield, as well as a good layout of the headlights and bumper with an integrated spoiler. Convex and slightly wider fenders, as well as a high rear end with an integrated spoiler, in turn, contribute to improved aerodynamic performance. For this purpose, roof drains and exterior mirrors with good aerodynamics are also used.
34% of the body metal in Renault 19 is processed in the following way:
- One-sided galvanization of the doors, the lower transverse support beam of the windshield, the dividing wall of the heating, the outer part of the bumper, the lower transverse support beam at the rear, as well as other parts of the bottom of the body, was made.
- The protruding parts of the hood and radiator are double-sided galvanized to protect against the abrasive effects of sand and dirt.
- Made zinc-containing coating of the wings.
Engine and transmission
The engine is located transversely in front with an inclination of 12°back in the right side of the engine compartment (when viewed along the way). To the left of it is the gearbox. Gasoline engines are mounted on an auxiliary frame on three points of support (two in front, one in back). The lower transverse suspension arms are also attached to it. Diesel engines, unlike gasoline ones, are mounted in the engine compartment on a rocking suspension, which provides improved engine noise insulation. This mount provides effective vibration suppression at idle, reduces engine noise at high speeds, and prevents the engine from shaking when driving on rough roads.
Transmission
All modifications of Renault 19 are equipped with gearboxes manufactured by "Renault" JB type. This is a transverse gearbox with a lightweight metal housing. Depending on the model, the gearbox has 4 (JBO type) or 5 (type JB3) speeds. The JB3 gearbox is designed for higher torque. Both types of gearboxes are equipped with a reverse gear interlock.
Suspension
The Renault 19's suspension is very different from the Renault 21's and is more reliable. The front suspension consists of MacPherson struts supported by transverse swing arms.
The longitudinal guiding forces are taken over by the transverse stabilizer. From above, the MacPherson struts are attached with an elastic suspension to the casing of the wheel arches.
Depending on the engine, Renault 19 is equipped with two different types of rear axle:
- Models with engines up to 65 kW have one torsion bar built into the rear axle tube with a transverse stabilizer. The suspension group of this type consists of two longitudinally swinging arms attached to the body with the help of guide tubes. This axle design was used on other models and was improved for the Renault 19.
- Models with engines of 65 kW and more have four torsion bars, two of which act as stabilizers. In this type of suspension, both longitudinal swing arms are interconnected by a cross member. This axle design has been used in various sports models «Renault».
Passive safety
- The already mentioned auxiliary frame provides the necessary safety in a frontal collision. It is attached at four points to the front spars, and the radiator, trailing arms and steering gear are respectively attached to it.
- Modifications of the GTX and TXE models (from 5/92RT) optionally equipped with an anti-lock braking system. We are talking about the third generation anti-lock braking system manufactured by Bendix (Bendix). Along with ventilated front disc brakes, it also includes dual load-sensing brake force limiters on the rear brakes.
- Since November 1992, the Renault 19 could optionally be equipped with an airbag for the driver and a belt tensioner for the front passenger.
The airbag is located in the steering wheel. An electronic sensor evaluates the impact force in the event of an accident and ignites a gas generating charge that inflates the airbag. For effective protection of the driver wearing a seat belt, the volume of the airbag is approximately 35 liters. It is filled with nitrogen in 25 m s after the ignition of the gas-forming charge. Nitrogen, as the main component of the air we breathe, is completely safe for humans and the environment.
The belt tensioner immediately releases about 70 mm of the seat belt in the event of a collision. In a frontal impact, the sensor activates a small gas generator, the gas escaping from which acts explosively for a fraction of a second on the piston in the cylinder. The piston is connected to the seat belt buckle in such a way that, when actuated on the buckle, the associated seat belt is also tightened.
In a side or rear impact, neither the airbag nor the belt tensioner will deploy.
