An adjustment arrangement for adjusting an adjustable element of a motor vehicle, which has a motorized or non-motorized drive unit, wherein the drive unit has, as train components, a hollow cylinder and a rod axially guided therein, wherein the adjustment arrangement has a drive spring arrangement with a drive spring, wherein, for guiding the drive spring during operation of the adjustment arrangement, a tubular guide having a circumferential radial guide surface extends outside or inside the drive spring. It is proposed that the circumferential radial guide surface of the tubular guide has a geometry that differs from that of a cylindrical lateral surface, such that the drive spring, during operation of the adjustment arrangement, can only contact the circumferential radial guide surface of the tubular guide in the circumferential direction around the geometric drive axis with individual drive spring circumferential sections.
An adjustment arrangement, in particular a spindle drive, for adjusting an adjustable element, in particular a flap, of a motor vehicle, wherein the adjustment arrangement has two joint parts adjustable relative to each other along a geometric drive axis between a retracted position and an extended position for transmitting linear drive movements to the motor vehicle, each of which forms a drive connection with a counter-joint part on the motor vehicle side for coupling to the adjustable element on the one hand and to the motor vehicle on the other, wherein the adjustment arrangement has a motorized or non-motorized drive unit, wherein the drive unit has a drive train with several drive-coupled train components in order to transmit a force introduced into the drive connections, wherein the drive unit has, as train components, a hollow cylinder and a rod axially guided therein, wherein one of the joint parts is axially fixed to the hollow cylinder and the other of the joint parts is axially fixed to the rod, wherein the adjustment arrangement has a drive spring arrangement with a drive spring which acts on the two joint parts by providing an axial spring force, wherein a tubular guide, which has a circumferential radial guide surface, extends outside or inside the drive spring to guide the drive spring during operation of the adjustment arrangement, wherein the circumferential radial guide surface of the tubular guide has a geometry that differs from that of a cylindrical lateral surface, such that the drive spring, during operation of the adjustment arrangement, can only contact the circumferential radial guide surface of the tubular guide in the circumferential direction around the geometric drive axis with individual drive spring circumferential sections.
The adjustment arrangement, in particular a spindle drive, for adjusting an adjustable element, in particular a flap, of a motor vehicle, wherein the adjustment arrangement for transmitting linear drive movements to the motor vehicle has two joint parts adjustable relative to each other along a geometric drive axis between a retracted position and an extended position, each of which forms a drive connection with a motor vehicle-side counter-joint part for coupling with the adjustable element on the one hand and the motor vehicle on the other hand, wherein the adjustment arrangement has a motorized or non-motorized drive unit, wherein the drive unit has a drive train with several drive-coupled train components in order to transmit a force introduced into the drive connections, wherein the drive unit has as train components a hollow cylinder and a rod axially guided therein, wherein one of the joint parts is connected to the hollow cylinder and the other of the joint parts are each axially fixedly coupled to the rod, wherein the adjustment arrangement has a drive housing with an outer housing tube and an inner housing tube, which telescopically slide into each other during an adjustment between the retracted position and the extended position, and wherein, for guiding the inner housing tube on the outer housing tube during operation of the adjustment arrangement, the inner housing tube has a circumferential radial outer surface, wherein the circumferential radial outer surface of the inner housing tube has a geometry that differs from that of a cylindrical lateral surface, such that the outer housing tube in operation of the adjustment arrangement can only contact the circumferential radial outer surface in the circumferential direction around the geometric drive axis with individual housing tube circumferential sections.
