摘要： A hydraulic piston machine including a housing, a shaft that is able to rotate relative to the housing, and a cam secured to one of the housing or the shaft. A cylinder block includes pistons that are able to move in the cylinder block opposite the cam in order to generate relative rotation between the cylinder block and the cam. The cylinder block is linked in rotation to the other of the shaft or the housing. A mechanism forms rotation guide bearings for guiding the rotation of the shaft relative to the housing, which mechanism includes a tapered plain bushing interposed between a housing element and an element linked in rotation with the shaft and in which the tapered plain bushing includes a radial through-slit extending through the entire radial dimension of the bushing.

摘要： A hydraulic system has two hydraulic circuits, each with a pressure generating unit acting on an actuator unit. The generating units are slot-controlled radial piston pumps and form a pump assembly with a single common pump support and single common rotor. The rotor is rotatable on a free protruding section of a common support hub and has piston-receiving bores on axially offset planes. The hub has two first and two second fluid bores. The first bores communicate with first pump connections and first control openings on the hub on a first plane, and the second fluid bores communicate with second pump connections and second control openings on the hub on a second plane. A first and a second adjustment frame, each having an eccentric ring and acting on the pump pistons, are disposed on respective planes perpendicular to the main axis and independently guided in a linearly movable manner.

摘要： A radial piston machine includes a housing, rotor, first braking member, and brake ring with a second braking member. The rotor is mounted in the housing to be rotatable relative to an axis of rotation, and has an end face facing in a direction of the axis of rotation. The first braking member is positioned on the end face. The housing has a body defining a ring-shaped extension relative to the axis of rotation. The brake ring is positioned to surround the extension and is configured to be movable in the direction of the axis of rotation so as to bring the second braking member into braking engagement with the first braking member. The brake ring is further configured to positively engage with an inner radial side of the extension to limit a twisting between the housing and brake ring.

摘要： A hydraulic radial piston engine has a lifting ring fixed to the casting, a rotor mounted opposite the lifting ring such that it is rotatable about an axis of rotation, multiple piston seats aligned radially in the rotor relative to the axis of rotation, and multiple pistons each displaceably mounted in a piston seat and which, over at least part of their length, have a non-circular guiding and sealing cross section that is coincident with a non-circular guiding and sealing cross section of the piston seats. Circularly cylindrical rollers are borne by the piston. With a given overall size, a greater swept volume per piston is possible and therefore a greater torque is produceable.

摘要： A hydraulic radial piston engine which comprises a lifting ring which is fixed to the casing, a rotor mounted opposite the lifting ring such that it can be rotated about an axis of rotation, a large number of piston seats aligned radially in the rotor with respect to the axis of rotation, a large number of pistons, each of which is displaceably mounted in a piston seat and which, over at least part of their length, have a guiding and sealing cross section that deviates from a circular shape and which is coincident with a guiding and sealing cross section of the piston seats which deviates correspondingly from the circular shape and remains constant as far as the outside of the rotor, and circularly cylindrical rollers which are borne by the pistons in bearing seats and aligned with their axis of rotation in the direction of the axis of rotation of the rotor, to support the pistons on the lifting ring. The rollers have two end faces which run at right angles to their axis of rotation, and face away from each other. The invention is based on the object of developing a hydraulic radial piston engine which has the features of the preamble of patent claim 1 in such a way that, with a given overall size, a greater swept volume per piston is possible, and therefore a greater torque can be produced, and that the rollers are secured in their position in the axial direction in a simple way. The intended object is achieved by the piston seats having two wall sections aligned at right angles to the axis of rotation of the rollers, and by the distance between the two end faces of a roller being only slightly less than the distance between the two flat wall sections of the piston seats.
