The VTP modular transmission system developed by VDS represents an optimal configuration of mechanical components and hydrostatic variators. This system is based on the principle of hydrostatic-mechanical power splitting and offers up to three superposition ranges (1R, and 2V), it can be equipped with/without high-low group, depending on the version.

The heart of the VTP transmission system, consisting of two drive trains (mechanical and hydrostatic), is a double planetary set at the transmission output (summing planetary module). In purely hydrostatic operation, the reversing planetary set is only active at low speeds, while the second planetary set superimposes mechanically and hydrostatically transmitted power. This results in high tractive force potential and a large gear spread, while at the same time minimizing mechanical effort.

The VTP transmission system is already used in almost all “off-highway” vehicle segments. Thanks to its modular design and availability in various sizes, which can be combined with different variators, the VTP system offers the flexibility to provide cost-efficient solutions even for small quantities. In this context, the VTP gearbox system is the ideal solution and enables the integration of all components required for stepless gearbox adjustment in a “basic module” and in any size.
