Recently, Allison Transmission, the world's leading supplier of medium-heavy commercial automatic transmissions and hybrid power systems, said that its automatic transmission was successfully matched with an automatic urban passenger car to Santa Fe, Argentina. Mercedes-Benz 1725 high-floor articulated coach manufactured by COLCAR Company is Argentina's best-selling Mercedes-Benz model, equipped with Allison T270R gearbox (built-in hydraulic retarder) and front-mounted engine.
Daniel Dobrilovich, COLCAR's service manager, explained: "We have been using articulated coaches made in Argentina for five years and equipped with front-mounted engines and manual gearboxes. Although manual transmissions can meet our needs, rear wheel brakes Due to overuse, the film is replaced on average every two and a half months. Frequent wear and tear on this important part is the main problem."
Dobrilovich said that because of this, they decided to use Mercedes-Benz articulated passenger cars equipped with Allison automatic transmissions and front-mounted engines. This Mercedes-Benz passenger car with its Metalpar chassis and air suspension received high praise and can transport 200 passengers at a time. Dobrilovich said, "Automatic high floor buses perform well and perform well. Compared to manual transmissions, Allison automatic transmissions have significant advantages in improving vehicle handling and reducing the number of vehicle maintenance. In the past, people often It is thought that the vehicles equipped with automatic transmissions consume more fuel. After actual comparison, we found that the automatic vehicle consumes the same fuel as the manual transmission."
Passenger buses equipped with Allison transmissions avoid common clutch wear problems for manual transmissions. It also has many advantages. For example, a hydraulic retarder not only helps the vehicle to stop accurately but also extends the life of the vehicle's braking system. Dobrilovich explained: "When approaching the parking spot, the driver only has to apply the brakes lightly and the automatic transmission can brake precisely. This reduces the maintenance of the vehicle."
Roberto Larossa, Allison Regional Manager for South America, said that buses equipped with Allison Transmission will not overuse the engine, providing a smooth and quiet driving experience for passengers and drivers. Therefore, the passenger car equipped with Allison automatic transmission helps maintain the stability of traffic flow and the vehicle can quickly brake and accelerate. These advantages are particularly important when the vehicle is driving in a heavily congested Santa Fe city. Because the Allison transmission requires no manual shifting, the driver can grasp the steering wheel with both hands while driving and concentrate on the road conditions.
