Method and device for automatically resetting zero position on hydraulic transmission device

Abstract

The invention discloses a method and device for automatically resetting a zero position on a hydraulic transmission device. In a pump chamber of the hydraulic transmission device, a handle on the hydraulic transmission device is reset to the zero position by an automatic zero-position resetting device; the hydraulic oil in the pump chamber is utilized to lubricate and maintain the automatic zero-position resetting device; and meanwhile, the integrated level is increased. On the basis of delicate design, the automatic zero-position resetting device used for the handle is mounted in the cavity of a shell of the hydraulic transmission device, so that the surplus space in the cavity is fully utilized and the hydraulic oil in the chamber can be used to lubricate and maintain the automatic zero-position resetting device; therefore no additional lubricating oil is needed, the maintenance cost is lowered, the integrated level is also increased and the three-dimensional space is efficiently reduced; the device is convenient to install and use; few components are use; the structure is simple to implement; and the production cost is lowered. Besides, a U-shaped arc rail is used for controlling the handle to reset, the zero-position resetting operation is high in speed and can be buffered, and the service life is longer.

Description

technical field [0001] The invention relates to a resetting method and device, in particular to a method and device for automatically resetting a handle on a hydraulic transmission device. Background technique [0002] At present, the hydraulic transmission devices used in various fields (including hydraulic transmission devices for fixed equipment and hydraulic transmission devices for mobile equipment) basically return the handle to the neutral position manually or mechanically, or restore the handle to the neutral position through the action of solenoid valves and other hydraulic components. , but all need to be lubricated by lubricating oil, the integration degree is not high, the system structure is complex, the three-dimensional space is large, and the production cost is high. Contents of the invention [0003] The object of the present invention is to provide a method and device for automatic centering of a hydraulic transmission device. The invention not only impr...
