Abstract
The utility model relates to a steering drive axle. The steering drive axle comprises an axle case, a main driver driven bevel gear, a differential mechanism, an inner half axle, steering main pins, a universal joint, a wheel braking device, an outer half axle, a hub speed reducer, a steering joint shell and a steering joint support, wherein the inner half axle and the outer half axle are connected through the universal joint; the steering main pins and the steering joint shell are fixedly connected together and are supported on the steering joint support by two rolling cone bearings; the upper and lower steering main pins are located on the same axis; the steering joint support is fixedly connected with the axle case; the inner half axle is connected with a half axle gear of the differential mechanism through a spline; the left end of the outer half axle is connected with a solar wheel of the hub speed reducer through a spline; and a planet carrier of the hub speed reducer is fixedly connected with a wheel hub. The half axle is divided into inner and outer parts which are connected through the universal joint, so that the half axle has power transmitting and steering functions; in addition, since the universal joint is an equal-angle-speed universal joint, the transmission of power is not influenced.
Description
Technical field
The utility model relates to a kind of steering drive axle.
Background technology
Construction machinery and equipment, in order to obtain maximum tractive force, improves its off-road capability, mostly adopts full-bridge to drive, and forward and backward bridge is drive axle.For the construction machinery and equipment that there is unit frame, turns to deflection wheel, must there is steering drive axle just can make car sedan-chair have transferring power and the function turning to concurrently.
Utility model content
The utility model is intended to address the above problem, a kind of steering drive axle is provided, and its semiaxis divides to be made inside and outside two parts and connects by CV joint, the function that has transferring power concurrently and turn to, can not affect the transmission of power, its technical scheme adopting is as follows:
A kind of steering drive axle, comprise: axle housing, main gear device driven wheel of differential, diff, inner shaft, steering yoke bolt, universal-joint, car side brake, outer semiaxis, wheel reduction gear, steering swivel shell and steering swivel bearing, described inner shaft is connected by universal-joint with outer semiaxis, together with described steering yoke bolt is fixed in steering swivel shell and by two tapered roller bearings, be supported on steering swivel bearing, upper and lower two steering yoke bolts are on same axis, described steering swivel bearing and axle housing Joint, described inner shaft is connected with the axle side gear of diff by spline, the left end of described outer semiaxis is connected with the sun wheel of wheel reduction gear by spline, pinion carrier and the wheel hub of described wheel reduction gear are fixed together.
On technique scheme basis, described universal-joint is CV joint.
On technique scheme basis, the right-hand member of described outer semiaxis is bearing in the hole of steering swivel shell by copper sheathing.
The utlity model has following advantage: its semiaxis divides to be made inside and outside two parts and connects by universal-joint, the function that has transferring power concurrently and turn to, therefore and because universal-joint is the transmission that CV joint can not affect power.
Brief description of the drawings
Fig. 1: cross-sectional view of the present utility model;
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, a kind of steering drive axle of the present embodiment, it is characterized in that, comprise: axle housing 1, main gear device driven wheel of differential 2, diff 3, inner shaft 4, steering yoke bolt 5, universal-joint 6, car side brake 7, outer semiaxis 8, wheel reduction gear 9, steering swivel shell 10 and steering swivel bearing 11, described inner shaft 4 is connected by universal-joint 6 with outer semiaxis 8, together with described steering yoke bolt 5 is fixed in steering swivel shell 10 and by two tapered roller bearings, be supported on steering swivel bearing 11, upper and lower two steering yoke bolts 5 are on same axis, described steering swivel bearing 11 and axle housing 1 Joint, described inner shaft 4 is connected with the axle side gear of diff 3 by spline, the left end of described outer semiaxis 8 is connected with the sun wheel of wheel reduction gear 9 by spline, pinion carrier and the wheel hub of described wheel reduction gear 9 are fixed together.
Preferably, described universal-joint 6 is CV joint.
Preferably, the right-hand member of described outer semiaxis 8 is bearing in the hole of steering swivel shell 10 by copper sheathing 12.
When work, because the propons of construction machinery and equipment is normal drive axle, therefore torque is passed to wheel nave by main gear device, diff, inner shaft, isogonism band universal-joint, outer semiaxis, wheel reduction gear all the time, make rotation of wheel, driving device advances, if back axle is also participated in driving, front-rear axle drives jointly, can obtain larger tractive force.While turning to, this steering drive axle drives track arm, makes steering swivel rotate and make front-wheel deflection around steering yoke bolt, realizes turning to of construction machinery and equipment, therefore and owing to having used CV joint not affect the transmission of its power.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
