Q:

How does a hydrostatic transmission work?

A:

A hydrostatic transmission works through the use of a pump connected to a mover that drives a hydraulic motor. The motor, powered through the generation of flow, is connected to the load. This can be used to transmit power from the primary mover to the load itself. However, many types of hydrostatic transmissions also use variable distance pumps or motors. This allows for the regulation of torque and power.

Hydrostatic transmissions take rotary power from a primary source, usually an internal combustion engine, and transmit that to a load with its own set of unique characteristics, according to Hydraulics & Pneumatics. This often necessitates the regulation of torque, power and speed. Hydrostatic transmissions can do this with a hydraulic motor. When different types of pumps and motors are added, more variables can be controlled in the power transmission process. Standard hydrostatic transmissions function only as gearboxes unless they are outfitted with these variable pumps and motors. Accordingly, the majority of hydrostatic transmissions use those pumps and motors to achieve greater utility.

Hydrostatic transmissions are often used in vehicles that have small engines and require variable speed outputs. For example, small riding mowers and some tractors have engines that utilize hydrostatic transmissions.

    How does a hydrostatic drive work?

    A:

    A hydrostatic drive works by either mounting the standard hydraulic system hardware onto a reservoir with an attached hydraulic motor or by bolting a housed hydraulic pump and motor to a mechanical axle. These different types of hydrostatic drives are installed in vehicles depending on the specific speed and industrial needs of the vehicle. They can be found in a variety of different industrial equipment.

    How does a Tiptronic transmission work?

    A:

    A Tiptronic transmission can function as an automatic transmission or a manual transmission depending on which setting has been selected. Tiptronic devices often have special performance settings to give the driver more control over a vehicles performance and make automatic mode feel more like a sports car.

    How does a dual-clutch transmission work?

    A:

    A dual-clutch transmission, also called an automated manual transmission or semi-manual automatic, is a transmission with internal gears that shift using two electro-hydraulically actuated clutches. The vehicle's computer chooses the ratios automatically, or the driver can choose the ratios using a shift lever or shift paddles on the steering wheel.

    Do transmission stop leak products work?

    A:

    Transmission stop leak products work for small or minor transmission leaks. If the transmission leaks a large amount of fluid, stop leak should not be used.
