Panhard Dyna Z

The Panhard Dyna Z was released in 1953 as the successor of the model of Panhard Dyna X and manufactured until 1960. A total of 303 541 units were built. His successor was the Model PL 17

Model development

The body of the Dyna Z was like that of his predecessor, originally made ​​of aluminum and had the front and rear sub-frame made ​​of tubular steel, which were joined by reinforcements of steel plates in the sills. During the year 1956, the aluminum sheets were gradually replaced by steel. In 1958 there were only the bumper, the tank, the cooling jacket of the engine and most engine and transmission parts from aluminum, but the overall weight of the car was still relatively low for a comfortable six-seater sedan.

Their modern design gave her a unique combination of great space, comfort, performance and economy with a low purchase price. However, the reliability was to be desired, as the car was suffering from severe motor and wind noise. The Tiger version had a tuned engine with a larger cooling jacket.

Models

Data of the model Dyna Z Tigre ( 1958)

  • Purchase price ( in the U.S.): $ 2,000 ( the price was at the level of a vehicle from the lower middle class, between the Volkswagen Beetle and the Peugeot 403).
  • Engine: Two cylinder, four- stroke boxer engine with 851 cc displacement, air cooling; Valve springs as roller bearings, concentric Torsionstäbe; Valve stem; Crankshaft and main bearings and roller bearings for " Panhard patent"; Bag cylinders with non-removable aluminum cylinder heads; dry cylinder liners; soft engine mounts, which dampen the rough running engine of the two- cylinder; Radial fan on crankshaft end; large cooling jacket made of aluminum with cooling fins.
  • Power: 50 hp (37 kW) at 5500 rpm.
  • Drive: Front-wheel drive. The drive shafts are concentric tubes with rubber spacers, universal joints at the differential and double universal joints ( constant velocity joints ) at the wheel
  • Transmission: 4- speed transmission with cable shift in a cast aluminum housing together with the differential gear; 2nd and 3rd gear synchronized; 2nd and 4th gear with helical gearing; Steering wheel gearshift. Unlike most front-wheel drive car with a longitudinal engine of Panhard has built the gearbox between the motor and differential gear. Engine, clutch, gearbox and differential are located one behind the other. The direct drive (1:1) is achieved on the 3rd gear; 4th gear is designed as an overdrive.
  • Clutch: friction clutch with cable operation. In some markets, there was also a magnetic coupling, which was filled with iron filings: When attached to the housing coil is energized, stiffen these chips and connect the fixed to the crankshaft clutch basket with the clutch disc on the transmission input shaft. The electrical energy is generated by a special double - alternator, a coil supplies current to the battery and the remaining electric power system and the other for magnetic coupling. When the engine is accelerated above idle speed, moves so slowly the clutch.
  • Empty weight: 815 kg
  • Fuel consumption: about 6 l / 100 km
  • Maximum speed: 144 km / h
  • Steering: with screw behind the front suspension, quick steering column.
  • Front suspension: two transverse leaf springs, bent downward; high ground clearance. No stabilizer, resulting in sharp cornering for lifting of the inside rear wheel. Steering arms and steering shafts rotate in jacks that are mounted in the eyes of the transverse leaf springs.
  • Rear Suspension: rigid axle on solid support levers acting on the torsion bars. The axis is a V- shaped tube between the rear wheels, which is mounted in the middle with an elastic bearing on the transverse support of the rear subframe. Sit on each side of three parallel torsion bars, which are connected on the inside. As with the front axle lacking a stabilizer.
  • Body: made ​​of steel sheet ( previous models: aluminum sheet ), streamlined shape, four doors, low air resistance ( drag coefficient: 0.26 ) despite flat, not flush to the frame side windows, windshield and rear window rubber seal and gutters.
  • Interior: six seats on two benches
  • Brakes: drum brakes in the wheels; Low pedal force despite missing brake booster; Brake drums made ​​of aluminum with riveted steel braking surfaces ( exchangeable); on later models with cooling fins.

Driving impressions

The aluminum tanks are often leaking at the level sensors. In sharp cornering with an empty trunk of the car lifts the inside rear wheel like a Citroën 2CV, despite the downward bending of the front transverse leaf springs. This was probably caused by the weight distribution and the spring rates. The chassis swallows big waves and holes. The driving stability is very good, despite the sometimes raised rear wheel. The steering is very smooth, although a servo support is lacking. Driver and front passenger sliding around on the smooth plastic covers the seat. The heating is very effective. Are doubly coupled to load the 4th gear must, but this is not a problem since the 3rd gear is designed as a direct gear. The reverse gear is hard to find. Due to the soft engine mounts the clutch for inexperienced drivers is only with difficulty gentle to use. The brake lights also serve as back-up lights (since the ignition switch is bridged on the rear light unit, the car can be started without a key so when the reverse gear and the foot brake ). The car has no steering lock, but the unusual ( in the U.S.) controls make it relatively theft proof. As an additional safety device with a main switch ( with a French two-letter abbreviation called ) on the steering column, the connection will be disconnected to the battery. As with modern vehicles of the 21st century, the turn signal, the parking lights, the main beam and the Zweitonhupe be operated with the same lever. This ensures that all of these functions are easy to find; the turn signal, however, can easily be confused with the high beam. For greasing the vehicle a complicated lift is needed, which at the time was not available in most gas stations. The vehicle is often cited as an example of an aerodynamic design. The comb - tail was not yet common.
