Triumph TR3 año 1959

The Triumph TR3 is a sports car produced between 1955 and 1962 by Standard - Triumph in England. The variant facelift, popularly but unofficially known as the TR3A, entered production in 1957 and the final version, not official the TR3B, was produced in 1962.

TR3

Although the car was usually supplied as a two-seater convertible, a rear-seat casual and bolted steel hard top were available as extras.

The car was powered by a dc 1991 straight-4 OHV engine of the production initially of 95 HP (71 kW; 96 PS), an increase of 5 HP over the TR2 thanks to the larger carburetors SU-H6-equipped. This was increased later to 100 HP at 5000 rpm by the addition of a "high port" cylinder head and the manifold expanded. The four speed manual gearbox could be supplemented with a unit of overdrive on the three major indexes, electrical and controlled by a switch on the dash. In 1956 the front brakes were changed from drums to discs, the TR3 thus becoming the first series production car to be assembled in such a way.

The suspension was by double Arms , manganese bronze trunnion , coil springs and shock absorbers of tube in the front, optional anti-roll bar, and with the worm and the direction of the stick. Unlike the MG of the same time, the steering mechanism and linkage had considerable play and friction, which increased with wear.

The rear was conventional springs of foil , with solid axle and lever shocks, except that the (box) of rails were hung below the axle. The wheels were 15-inches in diameter and 4.5 inches wide (increased from 4 inches after the first few TR2s ), with wire wheels 48 spokes optional. Wire wheels are painted generally, either body color or argent (silver), but matte chrome and bright chrome were also available. The front disk or drum brakes and drums rear had no servoasistencia.

The weight of the TR3 was significantly greater than the Morgan Plus Four and the Porsches 356, but not much more than the MGA and the MGB. All except Morgan, who shares the same engine, were substantially less potent.

Under most conditions the car was very responsive and forgiveness, but it had a some handling vices. The chassis, which was shared by the TR2, TR3, TR4 TR3A and had limited wheel travel, and the car was a little high and narrow for a true sports car. As a result, cornering very hard, the rear wheel on the inside would lift, causing sudden oversteer due to the increased load on the rear tire outside. This was particularly true with radial tires increasingly common, the suspension TR2/3/3A original was built with older designs of pneumatic diagonal in mind. The elevation of the wheel was more sudden than that of other cars, as that was caused by reaching the end of the suspension travel while there was still load on the tire, so that the load on the other (outside) rear wheel was a function discontinuous load in the curves, instead of simply changing the slope.

The TR3 is a true roadster, designed for sunny days, but with rain protection removable. Features a hood, convertible) (USA top ) that fits within and off and removable side curtains, allowing doors very low with the collar to the arm of the driver to rest. There are holes in the ground, with rubber stoppers, so that the cat initially supplied could be used from the inside of the car, like the Jaguar XK120. The optional heater was poor and the shut-off valve was under the bonnet (US hood ). A third person can get behind the seats, if absolutely necessary.

13377 examples of the "pre-facelift" original TR3 were produced, of which 1.286 were sold in the Uk, and the rest is exported mainly to the USA.UU.. as of Q1 2011 there were approximately 826 licensed and 115 SORN registered TR3/3a's with the DVLA .

Performance

A car of hardtop with overdrive tested by the british magazine The Motor in 1956 had a top speed of 105,3 mph (169.5 km / h) and can accelerate from 0-60 mph (97 km / h) at 10.8 seconds. A fuel consumption of 27.1 miles per imperial gallon (10.4 L/100 km or 22.6 _mpg-Us) was recorded. The car for the test costs EUR 1103 with taxes included.

Other figures were recorded:

"TR3A"

In 1957 the TR3 was updated with various changes, including a radiator grille with total width and this model facelifted is commonly known as the "TR3A" Triumph. However, the cars are not badged as such and the name "TR3A" was not used officially, ^[11][12] as is evident from the sales brochures today.The "TR3A" was built between 1957 and 1962.

Although the facelift TR3 is often referred to as the TR3A, it is badged as a "Triumph TR3"

The "TR3A" was a minor update from the TR3. The changes include the new front grille wide, outside door handles of the doors, starter handle with a key, and it came with a tool kit full of series (this was an option on the TR3). The total production run of the "TR3A" was 58.236. This makes it the third TR of best-selling after the TR6 and TR7 . The TR3A was so successful that the molds of the original panel finally wore out and had to be replaced. In 1959 a slightly modified version came out that had raised stamped under the hinges of the bonnet and the boot and door handles, as well as a section of the rear floor redesigned. In addition, the windscreen is fixed with bolts in place of the connectors Dzus used in the first models "To". It is estimated that only 9.500 of the original to be 58,000 built survive in the world today. ^{[ citation needed ]}

The Triumph TR3 was the first production car to include disc brakes standard, which were carried on in the face wash "TR3A". The car was known for its ability to stop better, which is a favorite of autocross.

The "TR3A" is often seen in vintage and production racing today. The "TR3A", despite being almost 50 years old, is still competitive in the class E-Production SCCA ( Sports Car Club of America ).

In June 1977, the American Road & Track magazine published an article titled "driving Impressions: TR3A & TR250 "in its issue of the 30th anniversary. Posted a time of 0-60 mph in 12.0 seconds, power output of 100 HP (75 kW) at 4800 rpm , weight gap of 2.090 pounds (950 kg) and fuel consumption of 28 miles per imperial gallon (10 L/100 km ;. 23 _mpg-Us)

"TR3B"

The "Triumph TR3B" is an unofficial name given today to the final version of the TR3, which was produced in 1962. It was offered concurrent with the TR4 , which started production in 1961. The "TR3B" was a special event short of production in response to the concerns of the dealers, the buying public may not welcome the TR4.

It had the body of the "TR3A" later. There were two series, one with a number of commission preceded by TSF of which were produced 530. One with the numbers of commission preceded by TCF of which were produced 2804. Both series were produced in part in parallel. The series TSF were identical to the last run of TR3As, so that with the engine of 2 litres, but already with the gearbox fully synchronized TR4. The series of TCF had the engine TR4 2.138 (2,2) liters. The engine is a, straight bar 4 push-, 3-bearing, with shirts wet. Had 09:01 compression and it was very stiff. It was equipped with two carburetors to YOUR H6. It had 105 HP (78 kW) at 4.650 rpm and 172 N · m (127 lbf · ft) of torque at 3,350 rpm. Arrived around 20 miles per gallon-US (12 L/100 km; 24 _mpg-imp) to 30 miles per gallon U.S. (7,8 L/100 km, 36 _mpg-imp). The maximum speed was limited to approximately 110 mph (177 km / h) by the transmission ratio, unless it had overdrive. Overdrive electric trip (Laycock-de-Normanville Type A) was available as an option and operated on second, third, and fourth gears. Appearance was identical to the later US-version of the "TR3A", so that with different tires, light head, the rest is very similar to the TR3, except for a few handles of the grill and wider doors. It weighed 2,137 lb (969 kg).
