CreepDrive™ Offering Expands!
Poclain Hydraulics is bringing even more value to its customers by strengthening its full systems offering. The company is leveraging its efforts through a strategic restructuring of its organization in order to focus on system solutions. The CreepDrive™ offering, with a new dedicated motor and pumps, all from the High Performance range of products, is a perfect example of the new strategic focus.
The expanded CreepDrive™ offering will address the needs of a wider range of applications. It was introduced at INTERMAT Paris in 2018.
The CreepDrive™ system, a true hybrid mechanical-hydraulic transmission, allows vehicles to work at very low constant speeds regardless of the engine speed, providing auxiliary systems with the power they need to perform work effectively. When the system is disengaged, the vehicle is able to drive at normal on-road speeds with no mechanical transmission efficiency losses.
The complete CreepDrive™ lineup contains 2 different sizes of motors, a range of pumps and a plug & play control kit including the CAN bus communication. The new motor called CDM20 provides up to 2,4 l of displacement with 2 speeds (possibility to switch from full to half displacement).
Considering the gear reduction ratio in the rear drive axle differential, the CDM20 can provide an overall torque ranging from 50,000 to 100,000 Nm (36,000 to 72,000 ft lbf). Other new features include a reinforced shift cylinder as well as an extremely robust design. This new motor rounds out the existing motor range by offering twice the speed and 3 times as much torque.
Despite this significant performance improvement, the motor length has only increased by 50 mm and remains lighter than comparable products to meet the needs and requirements of outfitters. Integration into a wider range of vehicle applications, including medium commercial vehicles where constant speed and accurate positioning are essential, is now easier. CreepDrive™ removes the added stress on braking and clutching experienced with trucks working at low speeds as well as the additional maintenance required to keep those systems working properly.
Replacing friction braking with hydrostatic braking acting as an integral decelerator reduces the need to feather the brakes. Also, radial technology eliminates the need for an additional reduction stage and offers some of the highest efficiencies on the market. This reduces fuel consumption and noise.
