Description
Technical field
The present invention relates to a kind of steering and driving axle devices of high-clearance, belong to vehicle steer axle technical field, more particularly to
One kind can generate self-reacting steering and driving axle device with ground.
Background technique
Hilly and mountainous land is mostly based on the ground such as irregular ground, hillside fields, and traditional tractor is in Hills transfer and farmland
When operation, tractor attitudes vibration situation caused by landform and ground is complicated and changeable, and unit riding stability is poor, driver's peace
Full property is difficult to ensure.Therefore, to guarantee tractor in the adaptability in mountainous region, realization tractor is needed in hillside fields vehicle body self-level(l)ing
A kind of novel steering bridge, it can adapt to road surface automatically, and posture active levelling device and walking mechanism can be cooperated to make vehicle body
Leveling.
The plot of Hills is usually uneven, and when tractor work, each tire cannot come into full contact with ground, leads
Actuating power and riding stability decline.Therefore a kind of novel steering bridge is needed, can be come into full contact with tire is made with ground.
The plot of hilly and mountainous land usually rough and uneven in surface and crop specie is identical, and the high road clearance not only can protect axle housing
From the influence at the raised position in ground, moreover it is possible to damage when reducing farming to crops.
All-wheel drive vehicles have biggish driving force and overcome obstacle, prevent the ability skidded.In many a11wheel drives
Tractor, preceding bridge also take into account the effect of drive axle other than as steeraxle.
But existing farm tractor front axle, while being adapted to ground, it cannot be guaranteed that each tire comes into full contact with ground,
It is easy to cause stability poor, easily the security risks such as rollover.
Summary of the invention
To solve the above-mentioned problems, it the object of the present invention is to provide a kind of steering and driving axle of high-clearance, is suitable for not advising
Then road conditions and hillside fields, and can guarantee that tire comes into full contact with ground, body gesture can be cooperated to level, keep the stabilization of vehicle body.
The present invention is a kind of steering and driving axle of high-clearance comprising front axle housing body passes through swinging shaft among front axle housing body
Hinged with bracket with front axle support, wherein front axle support is fixedly connected with bracket, guarantees that front axle housing body can be rotated around fuselage；
Front axle housing body both ends are connected with end assembly, and end assembly includes the end shell and knuckle for being connected to front axle housing body end, end
Outside is connected with knuckle in end housing.
Further, the front axle housing body is banjo axle, and the road clearance passs from axle housing convex closure to axle housing terminal linear
Subtract, raised the height of axle housing convex closure, to increase the road clearance.
Further, hinged between end shell and front axle housing body, guarantee that end shell can be rotated around front axle housing body；
Knuckle is articulated with end shell, guarantees that knuckle can be around end housing into rotation；Between the end shell and bracket of two sides
It is hinged with pull rod, is hinged with track rod between the knuckle of two sides.
Further, pull rod both ends are hinged with end shell and bracket respectively, front axle housing body respectively with end shell and before
Bridge bracket is hinged, and on irregular ground or hillside fields etc. when road conditions, the angle between wheel and front axle housing body makes it with change
The body gesture self-level(l)ing of heavy grade can be cooperated, and be adapted to irregular ground, and connecing for tire and ground can be enhanced
Contacting surface product, enhances driving safety and riding stability；
Further, front axle housing body, end shell, bracket and pull rod are hingedly in quadrilateral shape, ensure that the stabilization of mechanism
Property；
Further, connect in front axle housing body equipped with main reducing gear and differential assembly, with main reducing gear and differential assembly
Semiaxis in the two sides inner shaft that connects and the two sides being connect with two sides inner shaft by interior universal joint, semiaxis passes through in the two sides
Semiaxis outside universal joint connection two sides outside two sides；Its power by main reducing gear and differential assembly reach left and right inner shaft and it is left,
Universal joint and left and right middle semiaxis in the right side, are then passed to left and right outer universal joint and left and right outer semiaxis (transmission shaft) passes to left and right two
Wheel hub rotates driving wheel.
Further, the end shell and the knuckle be hollow, the front axle housing body and end shell
Hinge axes (rotation axis) and the knuckle and end housing hinge axis (main pin axis) intersect at the outer universal joint
Center.Therefore, it can avoid the automatic movement interference for adapting to road conditions, driving and steering.
A kind of steering and driving axle of high-clearance of the present invention, the advantage is that:
1. front axle housing body can be rotated around center swinging shaft, and can rotate around rotary shaft before and after the shell of end,
Guarantee that front axle housing body can adapt to the operating conditions such as irregular road conditions or hillside fields automatically.
2. the hinged pull rod between end shell and bracket, angle between wheel and vehicle bridge can be made with road condition change,
The contact area for enhancing tire and ground keeps the stabilization of vehicle body while adapting to road conditions automatically.
3. hinged quadrangularly between drag link and vehicle bridge ensure that the adaptation road condition change that mechanism can be stable.
4. wherein the rotating shaft axis of main pin axis, front axle housing body and end housing hinge intersects at outer universal center,
Can avoid turning to, driving and it is automatic adapt to move during ground do not interfere, also ensure in steering procedure that power is not
It is disconnected.
5. the road clearance successively decreases from axle housing convex closure to axle housing terminal linear, the high road clearance not only can protect axle housing from
The influence at the raised position in ground, moreover it is possible to reduce the damage to crops.
