System for attaching a wheel to a motor vehicle
View Patent ↗A system for attaching a wheel to a motor vehicle, having a wheel hub which bears on a drive shaft stub of the motor vehicle and to which the wheel to be attached is attached by way of a central fastening element. On one section the central fastening element has an external thread, by way of which the bolt is screwed to an internal thread of a wheel hub stub of the wheel hub, a slotted cone interacting with the central fastening element in such a way that when attaching the central fastening element to the wheel hub the slotted cone can be pressed against the wheel. The slotted cone here being braced on an outer face of the wheel hub stub and entering into a frictional connection with the wheel hub stub.
1. A system for attaching a wheel to a motor vehicle, the motor vehicle having an axle shaft stub and a wheel hub mounted thereto for attachment of the wheel, the system comprising:
a central fastening element having an external thread formed on one section thereof configured to mesh with an internal thread formed in a wheel hub stub of the wheel hub and an internal toothing; and
a locking safeguard for securing the attached wheel to the wheel hub, said locking safeguard including a locking pin movably disposed between a first position, in which said locking pin locks said central fastening element, and a second position, in which said locking pin releases said central fastening element, said locking pin having an external toothing, configured to mesh with said internal toothing of said central fastening element and to lock said central fastening element in the first position, and to become disengaged from said internal toothing of said central fastening element and to release said central fastening element in the second position.
2. The system according to claim 1 , wherein said external toothing of said locking pin and said internal toothing of said central fastening element form a toothing system.
3. A system for attaching a wheel to a motor vehicle, the motor vehicle having an axle shaft stub and a wheel hub mounted thereto for attachment of the wheel, the system comprising:
a central fastening element having an external thread formed on one section thereof configured to mesh with an internal thread formed in a wheel hub stub of the wheel hub; and
a locking safeguard for securing the attached wheel to the wheel hub, said locking safeguard including a locking pin movably disposed between a first position, in which said locking pin locks said central fastening element, and a second position, in which said locking pin releases said central fastening element, said locking safeguard including a carrier and a spring element accommodated in said carrier, and wherein said locking pin of said locking safeguard is supported for linear displacement in said carrier of said locking safeguard, said spring element pressing said locking pin into the first position, and said locking pin being displaceable from the first position into the second position against a spring force exerted by said spring element, said carrier of said locking safeguard having an external toothing configured to mesh with an internal toothing of the wheel hub.
4. The system according to claim 3 , wherein said locking pin of said locking safeguard is attached to said carrier of said locking safeguard.
5. The system according to claim 3 , wherein said external toothing of said carrier and said internal toothing of the wheel hub form a toothing system with torsional play.
6. The system according to claim 1 , which comprises an anti-theft safeguard interacting with said locking pin of said locking safeguard.
7. The system according to claim 1 , which comprises a slotted cone configured to interact with said central fastening element such that, when said central fastening element is being attached to the wheel hub, said slotted cone presses against the wheel, and said slotted cone is braced on an outer face of the wheel hub stub and enters into a frictional connection with the wheel hub stub.
8. The system according to claim 1 , which comprises driving pins fixedly connected to a brake disk and projecting at least partially into recesses formed in the wheel to be attached.
9. A system for attaching a wheel to a motor vehicle, the motor vehicle having an axle shaft stub and a wheel hub mounted thereto for attachment of the wheel, the system comprising
a central fastening element for attaching the wheel to the wheel hub of the motor vehicle; and
driving pins fixedly connected to a brake disk and projecting at least partially into recesses formed in the wheel to be attached, each of said driving pins being fixedly connected by way of a sleeve and a bolt to the brake disk, each of the sleeves, each of the bolts and each of said driving pins extending at least partially into a recess in a wheel rim of the wheel.
10. The system according to claim 9 , wherein said central fastening element has an external thread formed on one section thereof configured to mesh with an internal thread formed in a wheel hub stub of the wheel hub, and further comprising a slotted cone configured to interact with said central fastening element such that, when said central fastening element is attached to the wheel hub, said slotted cone presses against the wheel, and said slotted cone is braced on an outer face of the wheel hub stub and enters into a frictional connection with the wheel hub stub.
11. The system according to claim 9 , which further comprises a locking safeguard for securing the attached wheel to the wheel hub, said locking safeguard including a locking pin movably disposed between a first position, in which said locking pin locks said central fastening element, and a second position, in which said locking pin releases said central fastening element.
