Problems solved by technology

And because of the strength, the end connecting the torque amplifier and the gearbox has not been able to be directly connected, and a connecting rod must be used
As a result, too many connection transition parts make the structure too complicated when the torque amplifier is applied, and the installation is very inconvenient

Embodiment Construction

[0013] The torque amplifier of this embodiment is as figure 1 As shown, it includes a casing 1 fixedly connected in sequence along the main axis direction, a stator 3 clamped by front and rear spacers 2 and 3, and a casing composed of a rear cover 5 . A spool sleeve 6 supporting the input spool 12 is housed in the casing, a rotor 7 forming a cycloidal pin-wheel pair is housed in the stator 3 , and an output shaft 11 is supported in the back cover 5 . The inner hole of the rotor 7 is meshed with the opposite ends of the input linkage shaft 8 and the output linkage shaft 10 through an inner spline. The other end of the input linkage shaft 8 is connected with the valve core sleeve 6 through the dial pin 7, and the other end of the output linkage shaft 10 is connected with the output shaft 11 through the internal spline of the inner end hole of the output shaft 11. The input valve core 12 extends outwards with an input shaft with a connection structure, the connection structure o...

Abstract

The invention relates to an integrated torque amplifier, and belongs to the technical field of hydraulic pressure. The torque amplifier comprises an outer shell consisting of a housing, stators clamped by front and rear isolation disks and a rear cover, wherein the housing, the stators and the rear cover are fixedly connected in sequence along the direction of a main axial line; a valve core sleeve which supports an input valve core is arranged in the housing; rotors which form cycloid pin gear pairs together with the stators are arranged in the stators; an output shaft is supported in the rear cover; inner holes of the rotors are simultaneously connected with the opposite ends of an input linkage shaft and an output linkage shaft through inner splines in a meshing manner; the other end of the input linkage shaft is connected with the valve core sleeve through a shift pin; the other end of the output linkage shaft is connected with the output shaft through an inner spline in a transmission manner; the input valve core extends out of the input shaft with a connection structure. During use, the integrated torque amplifier can be directly connected with an external input device without a connection transitional piece, so that the connection structure is obviously simplified, and the integrated torque amplifier is very convenient to mount and connect.

Description

technical field [0001] The invention relates to a torque amplifier, in particular to an integrated torque amplifier, which belongs to the technical field of hydraulic pressure. Background technique [0002] Torque amplifier is a torque amplification device mainly used in agricultural machinery. It is mainly composed of rotor stator meshing pair, valve body, linkage shaft, partition plate, back cover, valve core sleeve assembly and so on. Its specific structure and working principle can be found in the Chinese patent literature with application number 201420406381.9 titled "A Closed Output Torque Amplifier" and application number 201110073070.6 titled "Torque Amplifier". [0003] According to the applicant's knowledge, in the prior art, when the torque amplifier is installed in the main engine of the agricultural machinery, one end needs to be connected to the steering column before it can be connected to the steering wheel; the other end needs to be connected to the connecti...
