Abstract
A front axle of a motor vehicle with steerable, driven or non-driven wheels on steering knuckles pivotably hinged at a wheel-guiding element with an upper and a lower bearing position, each of which accommodates a radial bearing for mounting a steering knuckle bolt with a pot-shaped sleeve with a sealed lubricant reservoir and forms a bearing bushing. A stop disk is arranged a bottom of the sleeve to absorb axial forces and roll bodies of the radial bearing are supported with the supporting surfaces at the stop disk.
Claims21
A front axle of a motor vehicle with steerable, driven or non-driven wheels on steering knuckles, which have been pivotably hinged at a wheel-guiding element with an upper and a lower bearing position, each of which with a pot-shaped sleeve with a sealed lubricant reservoir, accommodating a radial bearing for mounting a steering knuckle bolt and forming a bearing bushing, wherein
- the radial bearing includes a plurality of roll bodies arranged in an interior of the sleeve,
- a stop disk which absorbs axial forces is arranged at a bottom of the sleeve, the roll bodies including first supporting surfaces and being supported with the first supporting surfaces on the stop disk,
- the roll bodies also including second supporting surfaces opposite to the first supporting surfaces, and further comprising a pre-stressed disk spring placed on the second supporting surfaces of the roll bodies.
A bearing bushing for a steering knuckle mounting with a pot-shaped sleeve, accommodating a radial bearing and with a sealed lubricant reservoir, wherein
- the radial bearing includes a plurality of roll bodies arranged in an interior of the sleeve, and
- a stop disk is arranged at a bottom of the sleeve to absorb axial forces, the roll bodies including first supporting surfaces and being supported with the first supporting surfaces on the stop disk.
A bearing bushing for mounting a steering knuckle bolt, comprising:
- a pot-shaped sleeve having an interior and a sealed lubricant reservoir;
- a plurality of roll-shaped bodies arranged in said interior of said sleeve and adapted to be positioned between the knuckle bolt and an inside surface of said sleeve;
- and
- a stop disk arranged at a bottom of said sleeve to absorb axial forces, said roll-shaped bodies including first supporting surfaces in contact with said stop disk.
A front axle of a motor vehicle with steerable, driven or non-driven wheels on steering knuckles, which have been pivotably hinged at a wheel-guiding element with an upper and a lower bearing position, each of which with a pot-shaped sleeve with a sealed lubricant reservoir, accommodating a radial bearing for mounting a steering knuckle bolt and forming a bearing bushing, wherein
- the bushing includes a sealing unit which seals the mounting,
- the sealing unit comprising a spring-stressed sealing element,
- the radial bearing includes a plurality of roll bodies arranged in an interior of the sleeve, and
- a stop disk which absorbs axial forces is arranged at a bottom of the sleeve, the roll bodies including first supporting surfaces and being supported with the first supporting surface son the stop disk.
A front axle of a motor vehicle with steerable, driven or non-driven wheels on steering knuckles, which have been pivotably hinged at a wheel-guiding element with an upper and a lower bearing position, each of which with a pot-shaped sleeve with a sealed lubricant reservoir, accommodating a radial bearing for mounting a steering knuckle bolt and forming a bearing bushing, wherein
- the radial bearing includes a plurality of roll bodies arranged in an interior of the sleeve, and
- a stop disk which absorbs axial forces is arranged at a bottom of the sleeve, the stop disk having a coating of polyvinylidene fluoride (PVDF), the roll bodies including first supporting surfaces and being supported with the first supporting surface son the stop disk.
