Clément-Panhard

• 
  1896 – A . C. Krebs at the steering lever of his system car.
• 
  1896 – Electromagnetic gearbox from A. C. Kreb's car patent.
• 
  1896 - A. C. Krebs car patent drawing FR256344.

The 1896 Krebs system car (FR256344, GB189619774A) introduced several new features in the car design.

• The three point suspension system generalized (engine and chassis)

since we know that three points are enough to determine a plane.[1]

To these sides [of the frame of the car] I fix or suspend at three points provided with pivoted joints, the motor mechanism which is thereby placed out of the influence of the deformations to which the frame of the car is liable to be subjected during the motion.[2]

• The electromagnetic constant mesh gear box

I had imagined this arrangement to avoid the brutal shocks that the gears undergo when changing gear, a solution that seemed barbaric to me.[3][4]

• The speed shifting at the steering device

For the purpose of operating the electro-magnetic clutch, I employ a commutator arranged preferably under the handle bar and adapted to be operated in such a manner as to establish, according to five different positions, the electrical connections that correspond respectively to: rest; forward movement at low speed; forward movement at medium speed; forward movement at high speed; and movement in the rearward direction.[5]

• The damped steering and the rack and pinion steering gear

Upon the turntable of the fore-carriage is fixed a toothed sector in which engages a pinion mounted on the upper turntable and whose axle carries a toothed wheel situated in a box connected by two tubes to the box of the car. A second toothed wheel mounted on the steering spindle is connected to the first one by means of a chain passing through these two tubes. Elastic rods, consisting for example of coiled springs, are substituted for the links of the chain in the straightportions of the said tuges. By this means the chain is always taut and the springs neutralize the vibrations transmitted to the chain by the jolting of the fore-carriage and so prevent the said vibrations from being transmitted to the steering spindle.[2]

• The forward (positive) caster angle on the steering axis

To ensure the stability of direction by the means of a special arrangement of the fore-carriage, that is to say, to re-establish automatically the parallélism of the two axles of the vehicle when there is no tendency to keep them in any other direction, or after a temporary effort has caused them to diverge from said parallélism; ... The axle of the fore-carriage is situated behind the projection of the axis of the pivot pin in order to ensure the stability of direction above referred to [of a quantity which can vary from 1/7 to 1/8 of the distance which separates the points of contact of the two front wheels with the ground].[2]

• The metallic wheel hub system, Levassor to Krebs:

You would kindly give us permission to use your wheel hub system for which, since you say it is very good, it might be worth patenting.[6][7]

• Aesthetic

The car of Commander Krebs, resulting from very personal and new ideas, has a particular and original aspect. We will add that this aspect is very satisfying and more elegant than any car that we have been allowed to see so far.[1]

• 
  1899-05-06 – The Autocar: "The light Panhard car". The mechanical version of the electromagnetic constant mesh gearbox of the A. C. Krebs system car.
• 
  1900 – Clément-Panhard driven by a woman.
• 
  1900 - one of the first Spanish vehicles registered in the Balearic Islands.[8]
• 
  1900 – Mr Herbert Farthing collected his Clément-Panhard (VCP) from the docks at Southampton.[9]
• 
  1927 - The VCP at the first London-to-Brighton veteran car run in November 1927.
• 
  1946 – movie La revanche de Roger la honte: "In 1885. Roger Laroque, a courageous industrialist, is embroiled in a criminal intrigue by the deviousness of his mistress."
• 1950 – Clément-Panhard driving through Paris.
• 2004 – 1899 Panhard et Levassor – the Clément-Panhard Car (VCP) from A. C. Krebs: "a mechanical nightmare".[9]

In 1896 A. C. Krebs intended to design a car system simple, reliable, aesthetic and secure for beginners. The 1898 Clément-Panhard car inherited the 1896 Krebs patent features, and got new ones.

• The three point suspension system generalized (engine and chassis)

This principle is identical, although the front axle is simpler. With the central pivot axle the intention of A. C. Krebs is double:

• Make the front axle independent of the chassis so as to keep the chassis in a horizontal position even in the event that one of the steering wheels is lifted by an object in its path:

One may wonder why this arrangement, generally considered defective for high-speed cars, was adopted for this cart. This is due to the fact that the manufacturer had above all in view to establish a car of a moderate price, essentially maneuverable, able to make turns on the spot and never having to exceed the speed of 30 kilometers per hour. Under these conditions the steering by rigid axle was perfectly admissible.[10]

• Apply the caster angle principle (see below).
• The mechanical constant mesh gear box

The electromagnetic gearbox is replaced by a mechanical gearbox on the same principle of gears always in mesh. [11]

• The speed shifting at the steering device

The speed shifting is now located on the right side of the car.

• The damped steering and the rack and pinion steering gear

This steering principle is identical, although the rack and pinion system is simpler.

• The forward (positive) caster angle on the steering axis

This steering principle is identical :

The swivel pin extending up from the front, axle for carrying the front end of the vehicle body, is connected to the axle spring by a bracket pivoted horizontally to the spring, and the swivel pin is slightly inclined backward at its upper end so that a downward extension of its axial line will pass at a slight angle in front of the wheel axle. By this arrangement when the front axle has been turned more or less out of its position parallel with the rear axle for lateral steering or turning, and is then released, it will, automatically move-back into the parallel position.[12]

• The metallic wheel hub system

A. C. Krebs generalizes his metallic wheel hub system to the entire Panhard & Levassor range.

• Aesthetic Mr. de Nève said of his VCP in 1950:

It's a small Duke Clément-Panhard of 3 hp. A low, open, two-seater car, engine in the back, well made to show off, with a lady by its side.[13]

• The Krebs cone clutch

The Levassor cone clutch improved by A. C. Krebs (see patent above).

• Engine regulation on admission

A. C. Krebs introduce the engine regulation on admission, instead of the exhaust (see patent above).

• 1899 – The constant level carburetor (FR295792).
• 1900 – The water circulation pump (FR300040).

• 
  1901 – Cycles Automobiles Clément – advertisement for Clément-Panhard Cars.[17]
• 
  1901 – Advertising postcards for the Voiture Clément-Panhard (VCP): "What are they waiting for? Ah! it can only be a ... Clément-Panhard car".
• 
  1902 – The Clément-Panhard new model: "6 horsepower engine, electric ignition, wooden wheels, high-speed car."

In 1901, new features are introduced in the VCPs:

• Both hot tube and electric ignition (from 1900):

The ignition advance lever makes it possible to obtain all the speeds between two speeds of the gear change by suitably varying the engine speed.[14]

• A. C. Krebs irreversible worm gear steering and Ackermann system.
• Front suspension with two tweezer springs.
• Detachable gearbox locks

From 1901 John Stirling buys Clément-Panhard chassis to sell them in many countries with his own bodies.

To prove the robustness of the Clément-Panhards, in July 1901 John Stirling broke the record for crossing the United Kingdom from John-O'-Groat's to Land's End in 59 hours and 15 minutes.[18]

• 
  1901 – VCP Stirling: Parisian Phaeton.
• 
  1901 – VCP Stirling: delivery van.
• 
  1901 – VCP Stirling: miniature brougham
• 
  1901 – VCP Stirling: light dogcart.
• 
  1901 - Stirling light dog-cart.

1901 - At the autoshow, Clément presented an engine set that could be fitted to any bicycle. This engine is derived from the Krebs engine for the Clément-Panhard Car and is dependent on the Panhard & Levassor patents.

• 
  1901 - The Clément autocycle with the removable motor derived from the Krebs engine of the Clément-Panhard Car.
• 
  1901 - Advertisement for the Clément autocycle mentioning the dependence on the Panhard & Levassor patents of A. C. KREBS.

• 
  1900 - Clément-Panhard (VCP) Phaeton.
• 
  1906 - Ford model N.

It should be noted the many similarities in principle between the Clément-Panhard car of 1898 (see above) and the Ford model N of 1906, forerunner of the Ford model T:

• Intended for the general public;
• Solid and safe;
• Generalization of the suspension by 3 points and triangulations;
• Transverse spring on the front axle, so the VCP waddles as does the Ford T;
• A quasi-automatic gearbox etc.

Also the use of vanadium steel by Ford comes from a Panhard & Levassor racing car that crashed during a race in America.[19]
