Description

Novel three-pivot transmission steering mechanism

Technical Field

The utility model belongs to the technical field of three-pivot steering, and particularly relates to a novel three-pivot transmission steering mechanism.

Background

With the great improvement of the protection consciousness of people on the ecological environment, the application of the storage transport vehicle and the tractor with green, low carbon and energy saving in the fields of production, transportation, storage and the like has been more and more emphasized by various countries in the world, and the upgrading of the three-fulcrum steering mechanism as one of the most important parts of the electric tractor is urgent.

The traditional three-pivot tractor adopts a gear shaft rack structure in transmission, namely, gear shaft rack transmission, a rack is processed on a piston rod of a hydraulic cylinder, the rack is driven to linearly reciprocate by hydraulic pressure, the gear shaft is driven to steer left and right, however, the required steering force of the traditional slewing bearing structure is large, the steering force needs to be realized by arranging a hydraulic system, the overall dimension of the traditional mechanism is large, the space occupied by the rack in the transverse direction is large, an oil way needs to be arranged in the hydraulic transmission, and the whole steering system is not compact enough.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel three-fulcrum transmission steering mechanism to overcome the technical problem.

The technical purpose of the utility model is realized by the following technical scheme:

the utility model provides a novel three fulcrum transmission steering mechanism, includes the steering spindle and connects the epaxial wheel hub that turns to of steering spindle still includes the slewing bearing of connection on the three fulcrum frames, be connected with a slewing bearing on the slewing bearing, the last position of slewing bearing one side processing consistent hole of slewing bearing, the steering spindle is connected on a steering support, the steering support with slewing bearing's gear end is connected, motor output shaft on the three fulcrum frames passes the through hole, just makes gear on the motor output shaft end with slewing bearing's gear end meshes.

Furthermore, the slewing bearing comprises a support plate connected with the slewing bearing and connecting frames connected to two ends of the support plate, and each connecting frame is provided with a mounting hole for connecting the connecting frame with the three-pivot frame.

Further, the steering support comprises a steering plate connected to the gear end of the slewing bearing and a steering frame vertically connected with the steering plate, and the steering shaft is connected to the steering frame.

Further, the through hole has a circular shape.

Has the advantages that: the steering support is driven to rotate around the rotary support in a transmission mode of motor driving and gear transmission, so that steering is realized, the structure is more compact, the steering precision is higher, and the environment is protected.
