Description
Technical field
The present invention relates to fork truck rear steering drive axle field, particularly relate to a kind of rear steering drive axle slewing journal structure.
Background technology
At present, fork truck rear steering driving axis is generally individually without the drive axle driven, the cross-country ability of car load, driving
Power, climbing capacity are the most poor, thus cause final work efficiency poor, on the other hand, on irregular road surface, and drive axle
The bearing capacity being subject to is big, if the speed of service is too fast, accident easily occurs in fork truck, thus is badly in need of a kind of rear steering drive axle of design,
Improve the steering flexibility of fork truck, mounting process and dependability.
Summary of the invention
The present invention is directed to cross-country ability in prior art, driving force, climbing capacity and the most poor shortcoming of anti-Derailment Safety, carry
Supply a kind of rear steering drive axle slewing journal structure that a kind of steering flexibility is high, mounting process is good and dependability is good.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals:
Rear steering drive axle slewing journal structure, including sidesway cylinder, on sidesway cylinder piston rod cut with scissors by first connecting rod pin
Being connected to connecting rod, connecting rod saves arm by second connecting rod pin articulation steering, is provided with lining in knuckle arm, and the material of lining is carburizing
Steel (20CrMnTi)；By first connecting rod pin and the axial restraint of connecting rod and second connecting rod pin and the axial restraint of knuckle arm,
Make generation linkage reflection, promote knuckle around axle housing axial restraint；Not by axle each power effect, anti-wear performance at knuckle arm
Good, knuckle is served the effect of axial restraint.
As preferably, also including axle housing, be provided with lining between axle housing and knuckle arm, knuckle arm is axial by lining
It is fixed on axle housing.
As preferably, knuckle arm is fixedly connected with knuckle by straight pin and the first bolt, and knuckle arm drives and turns
Swinging to joint, the lower end of knuckle is fixedly connected with knuckle mounting seat by the second bolt, knuckle mounting seat is provided with
Angular contact articulated bearing, knuckle mounting seat is fixed on axle housing by angular contact articulated bearing.Because complete vehicle weight passes through axle housing
Acting on oscillating bearing, flat on irregular road, axle housing diagonal angle contact oscillating bearing produces the impulsive force of different directions, corner connection
The side force of the different directions that fork truck can be born by tactile oscillating bearing is converted into axial force.
As preferably, the first bolt and the second bolt are hexagon flange bolt.
Due to the fact that and have employed above technical scheme there is significant technique effect: by first connecting rod pin and connecting rod
Axial restraint and the axial restraint of second connecting rod pin and knuckle arm, make generation linkage reflection, promote knuckle around axle housing
Axial restraint；Because complete vehicle weight acts on oscillating bearing by axle housing, flat on irregular road, oscillating bearing is produced by axle housing
The impulsive force of different directions, oscillating bearing can bear not to the impulsive force in direction；Knuckle arm is provided with lining, main by turning
To power effect, knuckle is served the effect of axial restraint.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
The toponym that in accompanying drawing, each number designation is referred to is as follows: 1 sidesway cylinder, 2 first connecting rod pins, 3 connecting rods,
4 first bolts, 5 linings, 6 knuckle arms, 7 straight pins, 8 knuckles, 9 axle housings, 10 angular contact joint shafts
Hold, 11 knuckle mounting seats, 12 second bolts, 13 second connecting rod pins, 14 piston rods.
Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
Rear steering drive axle slewing journal structure, as it is shown in figure 1, include sidesway cylinder 1, on sidesway cylinder 1 piston rod 14 lead to
Crossing first connecting rod pin 2 and be hinged with connecting rod 3, connecting rod 3 saves arm 6 by second connecting rod pin 13 articulation steering, is provided with in knuckle arm 6
Lining 5.The material of lining 5 is 20CrMnTi, and wearability is good, and service life is up to 500,000 times；Not by axial force at knuckle arm 6
Effect, anti-wear performance is good, and knuckle 8 serves the effect of axial restraint.Also include axle housing 9, axle housing 9 and knuckle arm 6 it
Between lining 5 is installed, knuckle arm 6 is axially fixed on axle housing 9 by lining 5.
Knuckle arm 6 is fixedly connected with knuckle 8 by straight pin 7 and the first bolt 4, and knuckle arm 6 drives knuckle 8
Swinging, the lower end of knuckle 8 is fixedly connected with knuckle mounting seat 11 by the second bolt 12, and knuckle mounting seat 11 is installed
Angular contact articulated bearing 10, knuckle mounting seat 11 is had to be fixed on axle housing 9 by angular contact articulated bearing 10, the first bolt 4
It is hexagon flange bolt with the second bolt 12.The present embodiment use oscillating bearing 10 be model be the angular contact of GAC35S
Oscillating bearing, because complete vehicle weight acts on oscillating bearing by axle housing 9, flat on irregular road, contact joint, axle housing 9 diagonal angle
Bearing 10 produces the impulsive force of different directions, and the side force of the different directions that fork truck can be born by angular contact articulated bearing 10 turns
Turn to axial force.
Hereafter the design of steering and driving axle slewing journal structure and the selection of material improve All-terrain Forklift steering and driving axle and exist
Adaptability under the adverse circumstances such as mine, mud ground, sand ground.
In a word, the foregoing is only presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent
Change and modification, all should belong to the covering scope of patent of the present invention.
