Abstract
This utility model provide crawler tractor from return manual steering gear, it includes steering wheel, turn to cover, wherein, cover is turned to be arranged on tractor driving by turning member support indoor, cover cross section is turned to take the shape of the letter U, steering bearing it is provided with at the bottom of U-lag, sleeve pipe one end is turned to be connected with steering wheel by nut, the sleeve pipe other end is turned to sequentially pass through turning member support, turn to cover, it is connected with encoder after steering bearing, encoder is arranged on by encoder support and turns to cover one end, it is positioned at and turns to turning to of cover on sleeve pipe, to be set with torsion spring set, it is set with torsion spring on torsion spring set outer peripheral face.This programme uses purely mechanic design, and its service life is long, stable, relatively has preferable mechanically stable power.
Description
Technical field
This utility model relates to referring to from return manual steering gear of tractor technical field, especially crawler tractor.
Background technology
It is little and to advantages such as the adhesion properties of soil good (being difficult to skid) that crawler tractor has the compressive load per unit area to soil, at soil moisture and soft with preferably passing through performance, propulsive efficiency is the highest, it is greatly favored by consumers, existing crawler tractor steering wheel return equipment mechanism is complicated, maintenance difficult.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the length in service life of a kind of crawler tractor, stable from return manual steering gear.
For achieving the above object, technical scheme provided by the utility model is: crawler tractor from return manual steering gear, it includes steering wheel, turn to cover, wherein, cover is turned to be arranged on tractor driving by turning member support indoor, cover cross section is turned to take the shape of the letter U, steering bearing it is provided with at the bottom of U-lag, sleeve pipe one end is turned to be connected with steering wheel by nut, the sleeve pipe other end is turned to sequentially pass through turning member support, turn to cover, it is connected with encoder after steering bearing, encoder is arranged on by encoder support and turns to cover one end, it is positioned at and turns to turning to of cover on sleeve pipe, to be set with torsion spring set, it is set with torsion spring on torsion spring set outer peripheral face, one end and turn to cover U-lag at the bottom of inconsistent and fix, the other end is inconsistent with turning member support and fixes.
Described steering wheel is provided with the collar, and the collar is enclosed within by collar bearing and turns on sleeve pipe, the collar and turn to and be provided with shaft block ring between sleeve pipe.
This utility model, after using such scheme, after steering wheel twisting, just can automatically reset back under the active force of torsion spring, and this programme uses purely mechanic design, and its service life is long, stable, relatively has preferable mechanically stable power.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 turning member support connection diagram.
Detailed description of the invention
nullBelow in conjunction with all accompanying drawings, the utility model is described in further detail，Preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2，Crawler tractor described in the present embodiment include steering wheel 1 from return manual steering gear、Turn to cover 8，Wherein，Cover 8 is turned to be arranged on tractor driving by turning member support 12 indoor，Cover 8 cross section is turned to take the shape of the letter U，Steering bearing 4 it is provided with at the bottom of U-lag，Sleeve pipe 11 one end is turned to be connected with steering wheel 1 by nut，Sleeve pipe 11 other end is turned to sequentially pass through turning member support 12、Turn to cover 8、It is connected with encoder 14 after steering bearing 4，Encoder 14 is arranged on by encoder support 9 and turns to cover 8 one end，It is positioned at and turns to turning to of cover 8 on sleeve pipe 11, to be set with torsion spring set 7，It is set with torsion spring 6 on torsion spring set 7 outer peripheral face，Torsion spring 6 one end and turn to cover 8 U-lag at the bottom of inconsistent and fix，The other end is inconsistent with turning member support 12 and fixes，Described steering wheel 1 is provided with the collar，The collar is enclosed within by collar bearing 5 and turns on sleeve pipe 11，The collar and turn to and be provided with shaft block ring 2 between sleeve pipe 11.After the steering wheel twisting of the present embodiment, just can automatically reset back under the active force of torsion spring, the present embodiment uses purely mechanic design, and its service life is long, stable, relatively has preferable mechanically stable power.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
