Automated Manual Transmission meaning: Automated Manual Transmission or AMT, is also known as Semi-Automatic Transmission (SAT) or Clutchless Manual Transmission (CMT). As the name suggests, an. Transmit (transitive) To send or convey something from one person, place or thing to another. (transitive) To spread or pass on something such as a disease or a signal. (transitive) To impart, convey or hand down something by inheritance or heredity. Let’s bring that concept back to the purpose of the transmission. Below you’ll find a diagram of the power flow when the different gears in a 5-speed manual transmission vehicle are engaged. It’s the largest gear in the transmission and enmeshed with a small gear. A typical gear ratio when a car is in first gear is 3.166:1.

Good teaching starts with an operational definition of teaching. There are three common views of what constitutes teaching: teaching as transmission, teaching as transaction, and teaching as transformation (Miller, 1996).

Teaching as Transmission. From this perspective, teaching is the act of transmitting knowledge from Point A (teacher’s head) to Point B (students’ heads). This is a teacher­-centered approach in which the teacher is the dispenser of knowledge, the arbitrator of truth, and the final evaluator of learning. A teacher’s job from this perspective is to supply students with a designated body of knowledge in a predetermined order. Academic achieve­ment is seen as students’ ability to demonstrate, replicate, or retransmit this designated body of knowledge back to the teacher or to some other measuring agency or entity. From this perspective standardized tests are considered to be an apt measure of students’ learning. While there are specific instances when this approach is useful, I find little research support for this as a general approach to teaching and learning.

Teaching as Transaction. From this perspective, teaching is the process of creating situations whereby students are able to interact with the material to be learned in order to construct knowledge. Constructivism is an educational philosophy consistent with this view. Here, knowledge is not passively received; rather, it is actively built up or constructed by students as they connect their past knowledge and experiences with new information (Santrock, 2004). And just as each student’s past knowledge and experiences are different, so too is the interpretation, understanding, and meaning of the new information that each ultimately constructs.

Teachers are not expected to pour knowledge into the heads of learners; rather, they assist learners in their construction of knowledge by creating experiences where students’ old information can transact with new information to create meaningful knowledge (knowledge that is connected to something students already know). Academic achievement from a constructivist perspective is seen as students’ ability to use this knowledge to solve real-world problems or to create products or performances that are valued in one or more cultural settings.

Teaching as Transformation. From this perspective, teaching is creating conditions that have the potential to transform the learner on many different levels (cognitive, emotional, social, intuitive, creative, spiritual, and other). Transformational teach­ing invites both students and teachers to discover their full potential as learners, as members of society, and as human beings. The ultimate transformational goal is to help develop more nurturing human beings who are better able to perceive the interconnectedness of all human, plant, and animal life (Narve, 2001). Holistic education is an educational philosophy consistent with the transformative view (Miller, 1996). Learning is said to have occurred when these experiences elicit a transformation of consciousness that leads to a greater understanding of and care for self, others, and the environment. Academic achievement from this perspective is similar to self-actualization. That is, it is perceived as discovering and developing each individual’s unique talents and capabilities to the fullest extent possible. Academic achievement also involves becoming aware of the multiple dimensions of self and expanding one’s consciousness.

TRANSFORMING EDUCATION

`Learning can take place using all three views or approaches; however, it is my observation that the most powerful and sustaining learning experiences are created when transactional and transformational approaches are used predominately.

The transformational view of teaching incorporates the basic elements of constructivism and adds meaning, consciousness, and interconnectedness. Public schools operating from this perspective are places of inquiry where questions become just as important as answers. The primary role of teachers here is to enable students to discover and embrace their inner core and develop their interests and unique talents to the fullest extent possible; in other words, self-actualization. Curricula are a means to this end, not an end in and of itself. Academic achievement becomes closely linked with self-actualization and is highly individualized. Personalized goals as well as authentic assessment are used to describe learning. Schools and teachers are held accountable by assessing students’ and teachers’ movement toward personalized goals and by examining the extent to which students are engaged in meaningful learning experiences.

Hydrostatic transmission is a category of engine mechanics, and basically describes a system in which power is generated and transmitted by pressurizing and releasing fluid through specialized pumps. It’s also sometimes called “continuously variable transmission,” and it works by converting energy harnessed from the movement fluid through hydraulic pumps to the drive train of a vehicle. This sort of transmission can technically be used to power almost any type of machine, though it’s most commonly seen in heavy-duty machinery like tractors and backhoes. The transmission has the ability to provide a lot of power very quickly, but it isn’t usually very efficient when it comes to acceleration and maintaining high speeds. As such, it isn’t usually a good choice for passenger cars or trucks that spend most of their time on the highways.

How it Works

Motor vehicle engines usually come in several different types, and in most cases they’re named based at least in part of how they work. Passenger cars, for instance, are typically marketed with either “automatic” or “standard” transmissions, and both are terms that describe how the technology works — which is to say, whether the engine gears will shift automatically in response to driver speed, or whether they require driver engagement. Describing an engine as having a hydrostatic transmission is usually a statement about how the engine actually operates internally. In these cases, fluid is transferred from a piston pump to the motor through a series of tubes, and the energy generated in the process is what actually powers the vehicle.

There are no provisions for a clutch or a need for changing gears with this kind of transmission. To change speeds the operator simply moves the speed selector in the direction that represents the desired reaction. Typically, the farther forward the speed selector is pushed, the faster forward the tractor or vehicle will go, while pulling the lever to the rear while in motion will allow the vehicle to slow down. From a stopped position, pulling the lever backward places the vehicle in reverse.

Most Common Applications

This sort of transmission works really well for machinery that needs to have a lot of power without a lot of movement. Most machines that use it also have big enough engine boxes to hold its typically large size; it’s common in land-moving equipment and industrial machinery, particularly tractors, excavators, and forklifts. Anything that needs a lot of power and energy in short bursts can usually benefit from this sort of energy arrangement, though it’s not usually a good choice for vehicles that need speed. This includes cars, trucks, and equipment that needs to move in traffic.

Ease of operation is one of the biggest advantages to hydrostatic transmission. By eliminating the clutch pedal, the machine becomes much less complicated to operate. The vehicle's speed and power can be easily controlled with levers instead of a throttle, too, and the engine can also be used to control the descent down a hill or grade by using speed and direction rather than brakes.

This sort of transmission also makes certain jobs more efficient, and may allow the operator to get work done more comfortably than with the tiresome pushing of the clutch and the changing of gears. Once acclimated to the hydrostatic drive, most operators are able to manipulate the machinery with one hand without ever touching the throttle or the braking system until finished with the task.

Drawbacks and Disadvantages

The hydrostatic transmission model isn’t without its faults, though. The mechanics involved in transferring power from the hydraulic shafts to the to gearbox increases the odds of something becoming stuck. The power application often directs far too much torque to the wheels in a soft terrain situation, making them prone to spinning; also, in most cases, the tire speed is not as effectively managed as by a throttle. This can create a control issue that typically results in the operator losing the fight between gravity and soft surfaces.

Expense might also be a factor. Hydraulically powered drive systems tend to be more costly than more typical clutch and gear models. The fluid alone is often pricey to buy, and maintenance and service tends to be a lot more expensive, too. For these reasons, some people choose traditional clutch transmission systems for their machinery, particularly if it’s something that’s only used sometimes or for limited projects.
