Description

Powered and suspended wheel suspension with extreme turning

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an driven and sprung wheel suspension with extreme rotation.

BACKGROUND ART

At present, there is no solution for powered and suspended axle suspension with extreme high-angle steering. Existing drive-wheel solutions that do not have drive in the disk do not allow them to be rotated at higher angles due to the construction using a homokinetic joint. When dealing with extreme wheel steering, there is a problem with the combination of the large steering angle and the application of the torque that is applied to the wheels by means of the shaft.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are overcome by the driven and suspended extreme steering wheel suspension, whose first universal joint is rigidly connected to the axle steering gear and the second universal joint is rigidly connected to the axle differential according to the invention, which is characterized in that the first universal joint is rigidly coupled to a steering shaft which at its other end is rigidly coupled to a first double universal joint, wherein the steering shaft extends through a ver25 duct, wherein the first double universal joint is rigidly coupled to the rod, the rod extending through the cross hinge upper; which is pivotally connected by a split lever, which, at its other end, is pivotally connected to the hinge fixture by means of a first pin which is fixedly connected to the hinge fixture.

Furthermore, it is advantageous if an axial roller bearing is arranged between the upper and the upper hinge.

Furthermore, it is advantageous if a lower cross hinge is rotatably mounted on the underside of the hook, on which the locking nut is prevented from axial displacement, the lower cross hinge being rotatably connected to a lower lower lever which is supported by the other end a rubber sleeve is located by the lower lever and the hinge fixture.

Advantageously, the yoke is fixedly connected to the cross hinge by the upper and lower hinge, the opening of which passes through the PTO shaft, which on the one hand is firmly connected to the axially floating coupling, which is firmly connected to the other universal joint, and on the other with a second double universal joint, wherein the second double universal joint is rigidly connected to the horizontal axis of the pivot.

It is further preferred that a radiaxial roller bearing is mounted on the horizontal axis of the pivot for rotatably supporting the wheel.

Furthermore, it is advantageous if the split lower lever is pivotally connected in the middle to the hinge fixture by means of a second pin which is firmly connected to the hinge fixture.

The advantage of the designed device is its unique design, which made it possible to adapt its individual elements so that all the required characteristics of the wheel suspension - torque transmission, suspension, steering - while achieving a very above-standard angle of rotation, were maintained. The design of the device significantly influences the possibilities of steering wheels of vehicles.

Overview of the figure in the drawing

An example of a possible embodiment of the driven and sprung wheel suspension with extreme rotation according to the present invention is shown in an axonometric view in the attached fig. 1.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to an driven and sprung suspension of an extreme turning wheel, wherein the first universal joint 1 is rigidly connected to a steering shaft 2 which at its other end is rigidly connected to the first double universal joint 3, the steering shaft 2 extending through a vertical guide 4, wherein the first double cardan joint 3 is rigidly connected to the linker 5, the linker 5 extending through the upper cross hinge 6, to which a split upper lever 7 is rotatably coupled, with its other end rotatably connected to the hinge bracket 8 by a first pin 21 which is firmly connected to the hinge fixture 8.

An axial roller bearing 9 is disposed between the top 5 and the cross hinge 6. An underside cross hinge 10 is rotatably mounted on the underside of the hinge 5 on which the nut 11 is secured against axial displacement, the bottom cross hinge 10 being rotatably connected to the split lever 12 the lower end, which is pivoted by the other end in the hinge holder 8, wherein a rubber sleeve 13 is arranged between the lower lever 12 and the hinge holder 8.

A yoke 14 is fixedly connected to the cross hinge 6 by the upper cross hinge 10 and the lower hinge 10, through the opening of which a drive shaft 15 extends through the hole, which on one side is rigidly connected to an axially floating clutch 16 which is rigidly connected to the second universal joint 17 and the second double universal joint 18, wherein the second double universal joint 18 is rigidly connected to the horizontal axis of the rod 5.

A radiaxial roller bearing 19 is mounted on the horizontal axis of the pivot 5 for rotatably supporting the wheel 20.

The split lower lever 12 is pivotally connected in the middle to the hinge fixture 8 by means of a second pin 22 which is rigidly connected to the hinge fixture 8.

The driven and suspended extreme suspension wheel suspension allows the suspension wheel to be swiveled up to 75 ° to achieve high maneuverability while transmitting torque from the drive to the wheel. The steering pulse is applied to the first universal joint i and is further transmitted by the steering shaft 2 via the vertical guide 4. The vertical guide 4 allows spatial rotation of the steering shaft 2 and further permits movement of the steering shaft 2 in the vertical direction caused by the spring 20. The steering shaft 2 is further transmitted via the first double universal joint 3 to the wheel 5 of the wheel 20. The wheel 5 is mounted at the top in a cross-hinge 6 upper and bottom in the lower hinge 10 secured against axial displacement by the nut 11. 5 and the cross hinge 6 of the upper is mediated by an axial bearing 9.

The vertical springing movements are made possible by a double split lever 7 at the top and a split lever 12 at the bottom. The split upper lever 7, which is pivotally connected to the upper cross hinge 6, pivots about the first pin 21, which is fixedly received in the hinge bracket 13, when springed.

The split lower lever 12, which is pivotally connected to the lower cross hinge 10, is on the opposite side pivotally mounted in a rubber sleeve 13 which is rigidly connected to the hinge fixture 8. As it moves, it rotates around a second pin 22 which is rigidly connected to the hinge fixture 8.

The drive torque is applied to the wheel 20 via a second universal joint 17, which is rigidly connected to an axially floating clutch 16, which in turn transmits the torque to a fixed coupling.

-2GB 302519 B6 PTO drive shaft 15. The axially floating clutch 16 aligns the axial displacements of the drive PTO shaft 15, which are adapted to rotate the wheel 20. Furthermore, the torque from the PTO shaft 15 is transmitted via a rigidly coupled second double cardan joint 18 to the thrust 5. which allows rotation of the wheel 20 and transmission of axial and radial forces to the wheel.

The drive shaft 15 of the drive passes through the yoke 14, which stabilizes its position against deflection while allowing small axial displacements.

The device serves as part of an axle of, for example, a truck or vehicle that requires increased mobility and steering capability over a small area, along with the transmission of torque from the vehicle drive. Said wheel suspension, as part of the axle of the vehicle, makes it possible to drive into or out of tight spaces, to rotate with a small path radius and to have very good maneuverability.

Industrial applicability

The device can be used wherever the vehicles are used where the specified property is high from the controllability of the steering, for example, trucks in confined spaces, etc.
