Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Such as Figure 1-Figure 6 As shown, the present invention schematically shows a steering device.

[0018] The invention discloses a steering device, such as figure 1 , figure 2 As shown, it includes a valve body 5, an isolation disc 7 and a rotor-stator engagement pair 8, and the valve body 5 and the rotor-stator engagement pair 8 are connected to each other through the isolation disc 7 by means of connecting bolts. In the inner hole 5-5 of the valve body 5, an oil return ring groove 5-1, a left ring groove 5-2, a right ring groove 5-3 and an oil inlet ring groove 5-4 are sequentially formed (see figure 2 ), and is equipped with a spool sleeve 6 for switching the internal flow ch...

Abstract

The invention provides a steering device, including a valve body, an isolation disk and a rotor and stator engagement pair. The valve body and the rotor and stator engagement pair are connected with each other through the isolation disk, an oil return ring groove, a left ring groove, a right ring groove and an oil inlet ring groove are sequentially formed in an inner hole of the valve body, and avalve core sleeve for switching internal flow passages is arranged. The valve body of the steering device has two opposite end faces, and an oil inlet port and an oil return port, as well as a left oil port and a right oil port are formed in the two opposite end faces are respectively. The steering device not only reasonably sets the positions of the oil ports in the wall thickness positions between the adjacent ring grooves, so as to ensure no "cavity communication", but also skillfully utilizes screw threads and bottom holes thereof to realize the communication between the oil inlet port andthe oil return port, and solves the problem that there is no space in the separate production of a communication hole. The machining technology of each inclined hole is feasible, and the steering device can be installed conveniently without increasing parts and increasing the size.

Description

technical field [0001] The invention relates to the technical field of steering, in particular to a steering device. Background technique [0002] Hydraulic steering device is a steering device commonly used in engineering machinery, agricultural machinery and other engineering vehicles. Usually, the hydraulic steering device is mainly composed of valve body, rotating stator meshing pair, valve core, valve sleeve, isolation disc and other components, and its interior constitutes a complex flow path to meet steering control. The valve body has an oil inlet P and an oil return port T respectively connected with the oil supply and oil return circuits, and a left oil port A and a right oil port B connected with both ends of the steering drive cylinder. For a long time, the four ports on the valve body have been located on the same plane (see figure 1 ), which facilitates the flow channel design layout and machining inside the steering device. However, as the hydraulic steerin...
