Problems solved by technology

[0002] Tractors are favored by farmers for their simple structure, easy operation, light weight, flexibility, high efficiency, wide application and low price. The tractor steering device is very important for driving safety, reducing driving labor intensity, improving transportation efficiency and extending service life. It plays an important role. The original mechanical steering gear is heavy to operate, the operator is prone to fatigue, and it is easy to affect the steering performance. The existing hydraulic steering device is relatively easy to make the steering gear or other parts due to the high pressure of the hydraulic pump and unstable oil pressure. Parts are damaged and the structure is not reasonable enough

Abstract

The invention relates to a hydraulic tractor steering device. The hydraulic tractor steering device comprises a tractor chassis. A traction shaft at the foremost end of the tractor chassis is hinged to a tractor head through a traction connecting piece, a driver seat is arranged at the front middle end of the tractor chassis, and a hydraulic steering gear is arranged in front of the driver seat. One end of a control shaft is fixedly connected with a steering wheel, and the other end of the control shaft is connected with the hydraulic steering gear. The front face of the hydraulic steering gear is communicated with a pressure reducer. A gear hydraulic pump is fixedly connected to the foremost end of the tractor head. An oil tank is fixedly arranged above the middle of the tractor head. The gear hydraulic pump and the oil tank are respectively provided with an oil outlet and an oil returning port. One end of a bi-direction hydraulic stretchy steering oil cylinder is hinged to a connecting head on one side of the tractor chassis, and the other end of the bi-direction hydraulic stretchy steering oil cylinder is hinged to a traction connecting piece through a hydraulic column. The hydraulic tractor steering device is reasonable in structure layout, labor is saved during operation, and the steering accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural transport machinery, in particular to a tractor hydraulic steering device. Background technique [0002] Tractors are favored by farmers for their simple structure, easy operation, light weight, flexibility, high efficiency, wide application and low price. The tractor steering device is very important for driving safety, reducing driving labor intensity, improving transportation efficiency and extending service life. It plays an important role. The original mechanical steering gear is heavy to operate, the operator is prone to fatigue, and it is easy to affect the steering performance. The existing hydraulic steering device is relatively easy to make the steering gear or other parts due to the high pressure of the hydraulic pump and unstable oil pressure. Parts are damaged and the structure is not reasonable enough. Contents of the invention [0003] In order to overcome the above-mentione...
