Abstract
The invention relates to a hydrostatic drive ( ) with a hydraulic pump ( ) and a first hydraulic engine ( ) that is linked with the hydraulic pump ( ) via a first working line section ( ), the hydraulic engine driving a first drive train ( ). The hydrostatic drive further comprises a second hydraulic engine ( ) that is linked with the first hydraulic engine ( ) via a second working line section ( ), the second hydraulic engine driving a second drive train ( ). The second hydraulic engine ( ) is linked with the hydraulic pump ( ) via a third working line section ( ). According to the invention, an on-off valve ( ) is located in the first working line section ( ) and the second working line section ( ). When a slip arises at the first drive train ( ), said on-off valve can link the first working line section ( ) with the second working line section ( ) directly, that is while by-passing the first hydraulic engine ( ).
