This type is compact and ideal for applications with space constraints, besides being economical. This enclosed assembly is then bolted to an axle. The hydraulic pump, drive motor, and other components are all enclosed in a common housing, with the motor and the pump sharing a common valve. In this circuit, the input drive is the hydrostatic pump connected to the prime mover, and the output drive is the drive motor which is connected to the load. The hydrostatic transmission is a closed-loop circuit, where the fluid exiting from the drive motor outlet is returned to the hydrostatic pump without being sent to the tank. When rotated backward by 7º on a stationary vehicle, it is put into reverse transmission, by directing the fluid in the backward direction. When the swashplate is rotated backwards when the vehicle is in motion, it has a slowing effect. When the swashplate is rotated forwards by 15º, the vehicle begins moving in the forward direction. When the swashplate is vertical, no fluid is sent to the motor, and it is not operated. This is controlled by a swashplate, which is operated by a hand lever on the equipment. The pressure and amount of fluid sent to the drive motor dictates the speed at which the wheels move. The most famous type of CVT is the hydrostatic transmission, which finds application not only in heavy equipment, like forklifts, agricultural tractors, and industrial machinery, but also in vehicles, riding mowers, and even tanks. This problem can be solved by using a continuous variable transmission (CVT), also called a gearless transmission. This means that the engine power reduces momentarily when gears are being changed. The changing of gears, either manually or automatically, creates disruptions in the power transmission of the vehicle. Transmission can be either manual, where the driver himself has to change gears, or automatic, when the vehicle itself does this task. The transmission also performs this task of modifying the engine speed, by engaging and disengaging gears of different levels. IC engines have the limitation that they cannot operate below a specific rate, so this creates a problem while stopping or slowing down the vehicle. This is made possible by the vehicle’s transmission, which ‘transmits’ the power generated by the engine to the axle of the vehicle, making the wheels turn. These engines produce rotational motion, but the vehicle has to move in a linear fashion. Most modern vehicles work using an internal combustion engine. The Honda DN-01 motorcycle is the first consumer road vehicle that used a hydrostatic transmission.
