Abstract
A tractor steering axle capable of adjusting ground clearance mainly comprises a hub, a knuckle combined part, a master pin combined part, a master pin sleeve, a steering single-arm, a transverse tierod assembly, a crossbeam, a bracket, a pin shaft, a longitudinal tie rod and a steering double-arm, wherein the master pin sleeve and the crossbeam are welded to form a steering axle core support component; the flange of the knuckle combined part and the flange of the master pin combined part are connected through a positioning pin and a bolt; the master pin combined part is placed into the master pin sleeve and can rotate relatively; the upper end of the master pin combined part is fixedly connected with the steering single-arm and the steering double-arm; the steering single-arm and the steering double-arm are connected by the transverse tie rod assembly; the hub is mounted on the knuckle combined part and can rotate around the center of a knuckle; the bracket is hinged with the crossbeam through the pin shaft passing through the central hole of the crossbeam, and is used for supporting an engine; and the longitudinal tie rod pushes or pulls the steering double-arm to drive two wheels to rotate. The adjustment of two operation states, namely the conversion of the tractor steering axle between high ground clearance and low ground clearance, is achieved by rotating the knuckle combined part at 180 degrees and mounting.
Description
(1) technical field:
The utility model belongs to the trac. field, relates to the tractor steering bridge in crack, a kind of adjustable ground.
(2) background technology:
In the prior art, the trac. manufacturing enterprise of China develops crack, multiple highland or crack, lowland trac. in succession at the condition of service of different regions, and the trac. in this crack regularly has good result of use in certain zone.In recent years, domestic trac. cross-regional operation scope is increasing, and the road conditions of different regions, ridge height have certain difference, and the crack trac. can't be adjusted because of the ground Clearance regularly, and is poor at some operating area crossing abilitys, so scope of work is restricted.In addition, along with the increase of export volume, external user also has clear and definite requirement to the ground Clearance of trac..Therefore, design the tractor steering bridge in crack, a kind of adjustable ground, it is cooperated with drive axle, just can solve the problem that the height of crack trac. ground Clearance regularly can't be adjusted.
(3) utility model content:
The purpose of this utility model is to provide a kind of tractor steering bridge of crack, adjustable ground simple in structure, easy to use.
The utility model can be achieved through the following technical solutions above-mentioned purpose: as shown in Figure 1, the tractor steering bridge in crack, adjustable ground mainly comprises wheel hub 1,15, steering swivel component 2,14, stub component 3,13, main pin casing 4,12, turn to single armed 5, tie rod assembly 6, crossbeam 7, carriage 8, bearing pin 9, longitudinal tie 10 turns to both arms 11.It is characterized in that: main pin casing 4, crossbeam 7 constitute steeraxle core support part with main pin casing 12 weld togethers; The flange of steering swivel component 2 and steering swivel component 14 respectively with the flange of stub component 3 and stub component 13 by locating dowel pin and bolted connection, and can Rotate 180 ° change the installation site, adjust the ground Clearance; Captive joint with turning to single armed 5 in stub component 3 upper ends; Captive joint with turning to both arms 11 in stub component 13 upper ends, tie rod assembly 6 will turn to single armed 5 and turn to both arms 11 to link together; Wheel hub 1 and wheel hub 15 that tire is housed are contained in respectively on steering swivel component 2 and the steering swivel component 14, and can rotate around the steering swivel center; Carriage 8 is hinged with itself and crossbeam 7 by the bearing pin 9 that penetrates in crossbeam 7 interstitial holes, is used to support driving engine; Longitudinal tie 10 pushes away (or drawing) moving wheel hub 1 and wheel hub 15 that turns to both arms 11 drives that tire is housed and rotates.。
The utility model can be realized by technique scheme, and following beneficial effect is arranged:
Solve the problem that the trac. ground Clearance can't adjust according to actual condition from tractor steering bridge aspect, can enlarge the range of use of trac., helped the wider cross-regional operation of trac..
(4) description of drawings
Constructional drawing when Fig. 1 is crack, the tractor steering bridge lowland state in crack, adjustable ground of the utility model;
Constructional drawing when Fig. 2 is crack, the tractor steering bridge highland state in crack, adjustable ground of the utility model;
(5) specific embodiment
As shown in Figure 1, the tractor steering bridge in crack, adjustable ground mainly comprises wheel hub 1,15, steering swivel component 2,14, stub component 3,13, main pin casing 4,12 turns to single armed 5, tie rod assembly 6, crossbeam 7, carriage 8, bearing pin 9, longitudinal tie (or oil cylinder) 10, turns to both arms 11.
According to actual condition, with steering swivel component 2 and steering swivel component 14 simultaneously Rotate 180 ° respectively with stub component 3 and stub component 13 by locating dowel pin with after bolt is connected, reach state shown in Figure 2, realize the adjustment of crack, low, the high two kinds of ground of tractor steering bridge state.H+2X represents state lower bearing pin center, crack, highland and steering swivel centre distance.
