Problems solved by technology

In addition, the steering machine is rigidly fixed on the chassis or body of the walking machine through the steering frame, the angle of the steering wheel cannot be adjusted, and the comfort is poor.
With the increase in the size and load of the transport vehicle, the worm gear steering gear and the recirculating ball steering gear came into being. However, it is difficult to adjust the installation size, and the stagnation phenomenon occurs from time to time during the mechanical movement, which greatly increases the steering pressure. Steering force in the process, at the same time, it is difficult to achieve good ergonomics due to the limited space of the steering machine

Embodiment Construction

[0013] As shown in the drawings, the hydraulic steering machine of the present invention includes a steering shaft 2 and a steering wheel fixedly mounted on the top of the steering shaft 2 . The lower end of the steering shaft 2 is inserted in the drive cylinder 4 . The driving oil cylinder 4 is fixedly installed on the support 1, and is fixed on the vehicle frame or the chassis through the support 1. According to the installation position and space size of different vehicle models, the bracket 1 can adopt various structural forms.

[0014] The driving cylinder 4 includes a cylindrical cylinder body 41 with upper and lower end covers, and a driving cylinder piston 3 installed in the cylinder body 41 . The upper end cover 411 is fixedly installed on the upper end of the cylinder body 41 through the upper cover nut, and the lower end cover 422 is fixedly installed on the lower end of the cylinder body 41; A card slot, the annular card slot is clamped in the shaft hole of the u...

Abstract

The present invention relates to steering operation mechanical for motor tricycle, three wheeler, low speed transport vehicle, etc and is especially one kind of hydraulic direction machine. The hydraulic direction machine includes one shaft with annular slot, one steering wheel in the top of the shaft, one driving oil cylinder the shaft is inserted in, one executing oil cylinder with oil returning port and oil inlet communicated separately with the oil inlet and the oil returning port of the driving oil cylinder, and one rocker connected through a round head to the top of the piston in the executing oil cylinder. The hydraulic direction machine has driving mechanism and executing mechanism separately set and connected through middle hose, and this result in convenient design and installation of the steering mechanism and high adaptability.

Description

technical field [0001] The invention relates to a steering operation mechanism for three-wheeled motorcycles, three-wheeled automobiles, low-speed transport vehicles, tractors and wheeled self-propelled machines, in particular to a hydraulic steering machine. Background technique [0002] For a long time, agricultural machinery tractors, three-wheel vehicles, four-wheel low-speed vehicles, rice transplanters, etc. all use the steering wheel to drive the gear (or worm) on the steering shaft through the spline to rotate, and the gear drives the rack (or turbine and crank arm) The rotary motion is changed into linear motion, the rack (knuckle arm) is connected with the rocker arm on the main shaft of the front fork through the pin shaft (tie rod), the reciprocating linear motion is changed into swing motion, and the power is transmitted between the parts through rigid connections. The collision and friction between the components are transmitted to the steering wheel through th...
