摘要： The invention relates to a hydrostatic mechanical drive, comprising a hydrostatic radial piston motor (4) whose pistons are supported by rollers on an outerlying cam ring (8), said cam ring being rigidly connected to the drive housing (1), and guided in a rotatable piston support (9). Said piston support is rotationally fixed to an output shaft (11) and is guided between an axial bearing (6) and an axially mobile distributor piece (15) of an oil distributor (13), the distributor piece (15) pressing on the piston support (9) with an axial force. A brake (20) which acts on the output shaft (11) closes by means of a closing spring and opens when the hydraulic pressure exceeds a set value. According to the invention, the piston support (9) is displaceable within an axial limit and the closing spring (12) is located between the axial bearing (6) and the piston support (9), whilst the brake (20) is located on the other side of the piston support (9) between the latter and a part (14) which is rigidly connected to the drive housing (1). The brake is activated through the piston support (9). The distributor piece (15) generates an axial force in dependence on the hydraulic pressure. This axial force is adapted to the closing spring (12) in such a way that the brake (20) opens when the hydraulic pressure exceeds the set value.

Le carter présente une partie (2C) dite "couvercle de distribution" qui est située autour du distributeur (16). Ce couvercle de distribution (2C) et ce distributeur (16) présentent respectivement une première et une deuxième portion axiales (70, 72) dans lesquelles sont respectivement ménagés un premier et un deuxième logement (76, 78) destiné à recevoir une goupille (80) qui sert au blocage en rotation et qui, tout en permettant un léger débattement du distributeur (16) par rapport au couvercle de distribution (2C), empêche que le distributeur (16) ne se désolidarise du couvercle (2C) lors du montage du moteur.
