摘要： Une unité d'entraînement de puissance pour une structure d'inversion de poussée comprend un moteur réversible (10) dans un circuit hydraulique (36, 37) et possède des cycles de fonctionnement normaux de rangement et de déploiement. Dans un cycle de déploiement, la charge sur le moteur (10) constitue une aide et, dans l'éventualité d'un cycle de déploiement involontaire, la charge sur le moteur peut être sensiblement plus élevée. De manière à éviter cette charge accrue sur le moteur dans un cycle de déploiement involontaire, le circuit hydraulique possède une soupape d'auto-rerangement (100) qui détecte la charge élevée d'assistance dans l'éventualité d'un fonctionnement de déploiement involontaire et change le fonctionnement de l'unité d'entraînement de puissance pour faire marcher le moteur (10) dans un cycle de rangement pour empêcher d'exercer une charge élevée continue sur le moteur et sur la structure d'inversion de poussée.

摘要： The invention refers to hydraulic rotation transmissions and can be used in power transmissions and transmissions where the stepless ratio variation is essential. It can also be used as stepless speed transmission for vehicles (FIG. 1). Getting any transmission ratio with higher performance factor is achieved by applying in the hydraulic transmission new scheme, including motionless and movable bodies containing two coupled rotors, composing of camshafts with pistons and separated by motionless wall. Transmission ratio varies from 0 to maximal value displacing the movable body in axial direction by means of overhanging control arm.

摘要： It is an object to accurately control swash plate angles of movable swash plates of a hydraulic pump and/or a hydraulic motor. In a hydraulic stepless speed changing device, a hydraulic pump and/or a hydraulic motor, at least one of which is of a variable displacement type, and a hydraulic servo mechanism for controlling swash plate angles of movable swash plates of the hydraulic pump and/or the hydraulic motor are integrated and the movable swash plates are tilted thorough operation of a speed change operation lever. Load control mechanisms are formed by integrally providing actuators having a cylinder, a spool, and the like for sliding speed change drive members to the speed reduction side, the speed change drive members tilting the movable swash plates of the hydraulic servo mechanism. The load control mechanisms are actuated by pressurized oil led from a main oil path of a closed circuit formed by connecting the hydraulic pump and the hydraulic motor to the actuators.

摘要： A drive system for use in utility vehicles, such as agricultural forage harvesters and combines, includes a hydrostatic transmission having a pump driven by a main engine of the vehicle and having first and second motors respectively coupled to front and rear axles of the vehicle by way of first and second differential gear sets. The pump and one or both of the motors have a variable displacement determined by positioning respective swash plates through the agency of a lever, in the case of the pump, and by electronic devices, in the case of the motors, the electronic devices acting in response to control signals sent by a control arrangement, which in turn, operates in response to signals produced by pressure sensors associated with the motors and by signals produced by speed sensors associated with output shafts of the hydraulic motors. The control arrangement has a memory for storage of data, such as maximum legal ground speed and the ratio of the speeds of the axles as results from a given wheel size, and uses this information for controlling the hydrostatic transmission such that the vehicle does not exceed the speed, and the front and rear axles are driven so as to produce the same ground speed.

摘要： Hydrostatic transmissions are useful for propelling a machine to do work and travel relative to the ground. In performing work functions and during travel it is desirable to adjust machine speed to aid in handling the machine. The subject hydrostatic transmission control system includes a infinitely adjustable creeper hand lever which can be moved to any desired position and be maintained in the selected position until moved by the operator. A spring biased inching pedal can be used in combination with the creeper lever to further adjust the machine speed. This arrangement of components provides a control system for the hydrostatic transmission which can be adjusted and maintained at a desired setting.
