Hub and rotor separator and method

Methods and devices and clamps for separating a hub from a rotor of a rotor/hub assembly, including a platform having a top portion to receive the rotor and an opening to allow a pusher from a jack or press to pass through the opening, and a set of clamps configured to hold the rotor in a fixed position with respect to the platform while the pusher pushes through the opening to contact the hub to separate the hub from the rotor. The clamps are generally C-shaped and devoid of moving parts and slip inwardly upon the platform to hold the rotor while the pusher pushes upward to release the hub from the rotor, and the clamps have a slot to allow the clamps to rotate and store out of position in a non-use mode.

Brake disc and method for producing a brake disc

A brake disc includes a friction ring consisting at least partially of a first material and a brake rotor hat consisting at least partially of a second material that is different from the first material. The friction ring includes a flange formed in the axial direction, wherein the flange is connected to the brake rotor hat by means of at least one connection element. An intermediate piece is provided between the surface of the brake rotor hat in contact with the connection element and the connection element. In this way, a stable mechanical connection is created between the flange of the friction ring and the brake rotor hat.

The present invention relates to an electronic braked-integrated in-wheel motor driving device. According to one embodiment of the present invention, an apparently complicated driving device structure, which is formed due to the installation of a brake, can be avoided, and a product appearance of a wheel-chair, to which the in-wheel motor driving device is applied, can be simplified, whereby the driving device improves the visual appearance as well as the brake function and can thus enhance production competitiveness.

Leading-edge steering assembly
11584435 · 2023-02-21 ·

A leading-edge steering system is provided for a front suspension of an off-road vehicle. The leading-edge steering system is comprised of a spindle assembly that supports a drive axle assembly to conduct torque from a transaxle to a front wheel. A first rod-end joint pivotally couples an upper suspension arm and the spindle assembly, and a second rod-end joint pivotally couples a lower suspension arm and the spindle assembly. A steering rod-end joint pivotally couples a first end of a steering rod with a leading-edge portion of the spindle assembly. A steering gear is coupled with a second end of the steering rod and configured to move the steering rod, such that the spindle assembly rotates with respect to the upper and lower suspension arms. The leading-edge portion is configured to exert primarily tensile forces on the steering rod during travel over rough terrain.

Wheel hub and a system formed of wheel hub and brake element

A wheel hub for a utility vehicle includes a brake element abutment surface against which a brake element bears in an installed state, and a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and/or a receiving region for a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state.
