| Unit | SI system |
Hydrostatic transmissions (HSTs) are among the most versatile power transmission systems used in modern mobile and industrial machinery. By combining hydraulic pumps and motors into an integrated drive system, HSTs provide smooth, infinitely variable speed control, precise torque delivery, and seamless forward and reverse operation without changing the prime mover speed.
This comprehensive book presents the principles, construction, operation, selection, performance analysis, and practical applications of hydrostatic transmission systems using the SI System of Units. Designed for engineering students, faculty members, hydraulic professionals, and equipment designers, it bridges engineering theory with industrial practice through practical examples, engineering data, numerical problems, and real-world case studies.
The book explains both open-circuit and closed-circuit hydrostatic transmissions, their configurations, operating characteristics, displacement control methods, component specifications, and performance calculations. It also includes detailed case studies of actual hydraulic systems used in construction and mobile equipment, making it an invaluable reference for both learning and professional practice.
Whether you are designing a new hydraulic drive, maintaining heavy mobile equipment, or studying advanced fluid power systems, this book provides the knowledge required to understand and apply hydrostatic transmission technology with confidence.
