HYDROSTATIC TRANSMISSION MARKET INTRODUCTION

The powertrain efficiency deeply affects the performance of off-road vehicles like off-highway vehicles in terms of fuel economy, load capability, smooth control, etc.

The hydrostatic transmission (HST) systems have been widely adopted in off-road vehicles for providing large power density and continuous variable control, yet using relatively low efficiency hydraulic components.

HYDROSTATIC TRANSMISSION MARKET RECENT DEVELOPMENT AND INNOVATION

KYBhas created a hydraulic pump with modified swash plate control and a track motor with higher output and higher speed (compared to the level of the KYB's existing counterpart) to meet the demand of the distinct HST market for carriers, loaders, and other base machines movable with crawlers.The KYB product line has recently included this brand-new standalone HST. This hydraulic pump has a small footprint and is essentially a tandem pump made of two axial piston pumps with swash plates.

For usage in mowers or other vehicle applications, the KYB traditional equivalent (PSVH2-28 Series) utilised a pump control system that was actuated by a manual lever.To address the then-current market need for increased usability and simpler installation of extra functions, KYB had to implement a hydraulic pilot or electronic control system into the swash plate control. Based on traditional technology, KYB created this hydraulic pilot-controlled pump in response to demand. 

Parker'sIntegrated Hydrostatic Transmissions outperform rival products by terms of overall efficiency. This translates to higher horsepower for the mower deck or other features, as well as an improved ability to climb hills. The hydrostatic variable displacement pump, reservoir, filter, and industry-standard low-speed, high-torque motor are all included in one integrated package, cutting down on associated inventory and labour expenses. 

The HTG series transmission is a small, integrated product with torques up to 8180 lb-in, side loads up to 4000 lb, a shaft diameter of 1.25 inches, an integrated pump/motor assembly with the best Parker Torqmotor" TG gerotor motor in the business, an easy-to-service filter, a fan and pulley included, an integral reservoir (about 0.8 gal), quick fluid changes, and integral shock valves as standard. 

Sauer-Danfoss’ssmall LDU20 provides OEM equipment designers with an easy-to-install solution with best-in-class efficiency, low noise and vibration, and high lifetime by integrating a closed circuit variable displacement piston pump with direct displacement control (DDC) and a fixed motor. The closed circuit variable displacement piston pump and fixed motor are both included in the LDU20's single U-shaped enclosure. The LDU20 is the smallest hydrostatic transmission package in its class, measuring 170 mm long, 180 mm wide, and 240 mm high, making installation in OEM equipment with limited space simple. 

The LDU20 has a shaft centerline of 85 mm, which is smaller than the industry average of more than 100 mm. This is identical to classic Bantam Duty U-style (BDU) transmissions and outperforms the competitors in terms of power density.The LDU20, designed for vehicles with external charge sources, mounts directly to a customer's transmission housing, conserving space and facilitating installation by doing away with piping and housing.The use of a common charge pump for flow to steering or work has the added benefit of lowering the cost of the entire vehicle.

The Allison FracTran hydraulic fracturing transmission has been introduced, according to Allison Transmission. The transmission can handle up to 3,500 hp (2,609.95 kW) without requiring any hardware modifications. It was designed to handle 3,300 hp (2,460.81 kW) and 10,000 lb.-ft. (13,558.2 Nm) of input torque. The new Boomer tractor series from New Holland Agriculture, a division of CNH Industrial, is Stage V-compliant and offers greater performance without increasing size. The effectiveness and operator comfort of the tractors have been enhanced by new features.

With a variety of features, the new Boomer range also improves operator comfort and decreases fatigue. They come with the Cruise Control as standard on versions with hydrostatic gearbox. The EZ Speed function, which synchronizes the forward hydrostatic pedal and engine speed on hydrostatic transmission models, increases efficiency and versatility.

The engine speeds up when the user depresses the hydrostatic pedal when the hand throttle is in the low position. This guarantees they always have the appropriate ground speed and engine speed available. This is especially helpful in situations when, for instance, the operator wants to keep the tractor's noise level low when it is stopped and only turn up the engine speed when the tractor starts to move.

HYDROSTATIC TRANSMISSIONMARKET DYNAMICS

Emerging technologies in commercial-duty transmissions and powertrains include Hydrostatic transmissions and electric drive powertrains. In a hydrostatic transmission system, when the engine runs, it will rotate the drive shaft and the input shaft connected to it.

In a closed-circuit system, the movement of this input shaft will turn both the charge pump and piston pump, incorporating different mechanisms to facilitate shifting the automatic transmission gearbox. Electric drive powertrains are also emerging in certain end markets, such as transit buses, and are in part driven by efforts to reduce fuel consumption and greenhouse gas emissions.

Companies have been developing, designing and manufacturing gearboxes for the Construction & Agriculture industry and other sophisticated applications for many years and some have been working and developing hydrostatic-mechanical power split transmissions. The different versions should be developed as a gearbox designed specifically for mobile machinery that can fulfil strict requirements in terms of dynamic performance and reversing.

Hydrostatic-mechanical transmissions have been used in tractors for years. Construction machinery is now also set to benefit from the advantages of these systems, which is why a great deal of development work is currently being undertaken in the supply industry. 

Improvement in diesel consumption is the primary objective of these developments. Alongside the harmonious interaction between driver and machine, which itself has a huge impact on performance, the requirements in terms of dynamic performance play an equally important part and must therefore also be taken into account when designing transmissions.

Manufacturers offer the design of the whole system, combining its traditional mechanical know-how with strong electronic competencies. Able to support all the electric architecture topologies, leading the complete e-powertrain through a dedicated ECU, then sizing and integrating the most suitable electric modules: from motors and generators to inverters, batteries and battery management system to obtain the best performance for the entire system.

In order to better serve load-sensitive applications, ZF has developed its hydrostatic-mechanical power-split continuously variable technology, which is well-known for agricultural machinery. The new technology incorporates the ERGOPOWER transmission's advantages, which are valued by numerous industries. Due to significant increases in consumption and productivity, the transmission is ideal for the material handling industry in addition to leading applications like forestry machines and wheel loaders.

The market is seeing an increase in demand for more efficient drive systems as a result of rising fuel prices and more awareness of CO2 emissions. It is challenging to comply with emission requirements using traditional drives because they are imposed by the US EPA and EU rules, which set technological limitations and constraints on diesel engines. The unique demands for construction machines include high dynamics combined with heavy loads at low speeds. The brand-new ZF CVT gearbox technology meets these requirements precisely and to a level of economy that was previously unthinkable.

The adoption of new technologies, like CVT for industrial trucks, is accelerated by the rising demands for reduced fuel use and higher productivity.Future challenges for the diesel engine lift truck industry include a tendency toward lower engine speeds and the need for engine stability accomplished by a lack of dependence on the motor speed and driving speed. Both conditions are satisfied by ZF's continuously variable cPOWER.

In comparison to hydrodynamic transmissions and purely hydrostatic designs, hydrostatic-mechanical power-split transmissions offer significant advantages for these applications in terms of consumption. The advantages of continuously variable transmissions are evident across all speed ranges of a normal forklift operation cycle, during the controlled movement of the load, the positioning of transported materials, and the actual transfer. Because of the minimal amount of hydrostatic power used during this operation, maximum efficiency can be attained.

The mechanical portion of the transmission provides the majority of drive power after startup. This means that even in extremely brief loading cycles, the advantages of CVT technology can be seen in terms of fuel consumption.

Driving functions are best completed by the use of a complex hydraulic transmission-control unit and an onboard electronic device incorporated into the transmission. This results in a power management that is aligned in terms of sensitivity and driving comfort. ZF's expertise in transmission and vehicle system engineering is utilised by the cPower transmission series, which also makes use of well-known and tested building kit components.
