The work on the Maus would be divided between Krupp, responsible for the chassis, armament and turret and Alkett, who would be responsible for final assembly. The rear of the Maus in the Kubinka tank museum. The Maus tank was originally designed to weigh approximately 100 tons and be armed with a 128 mm main gun and a 75 mm co-axial secondary ...
Since the speed difference of the two tracks is independent of the gearbox selection, this makes the steering effect less pronounced at higher speeds; this means the tank has a longer turning radius at higher speeds, which is generally what is wanted. The system, however, produces only one radius for any given gearbox selection. [5]
The Leopard 2A4's motor is an MTU MB 873 Ka-501 water-cooled V12 diesel engine producing 1,479 hp at 2,600 rpm, coupled to a Renk HSWL 354 four-speed automatic transmission. The running gear of Leopard 2A4 consists of seven dual-tired rubber road wheels and four rubber-tired offset track return rollers on each side, with the idler at the front ...
The loaders noted that the IS-7 was comfortable and that the autoloader was easy to use. It was also able to achieve a top speed of 60 km/h, thanks to a 1050-horsepower diesel engine, giving it a power-to-weight ratio of 15.4 hp/tonne, a ratio superior to most contemporary medium tanks. Its armour was not only immune to the Jagdtiger's 12.8 cm ...

In September 1941, however, changes were made which lowered the effort to under 31 kg by changing the 3rd gear ratio, which lowered top speed in 3rd gear from 29 km/h to 25 km/h, but made shifting easier. Using the 5-speed gearbox allowed the T-34 to use 4th gear on terrain, with which it could reach 30 km/h. [76]
Crawl ratio is a term used in the automotive world to describe the highest gear ratio that a vehicle is capable of. Note that gear ratio, also known as speed ratio, of a gear train is defined as the ratio of the angular velocity of the input gear to the angular velocity of the output gear, and thus a higher gear ratio implies a larger speed reduction, i.e. the input speed is reduced more at ...
There is therefore one specific gear ratio at which the car can achieve its maximum speed: the one that matches that engine speed with that travel speed. [1] At travel speeds below this maximum, there is a range of gear ratios that can match engine power to air resistance, and the most fuel efficient is the one that results in the lowest engine ...
