A support jack for supporting semitrailers includes a vertically telescopically displaceable supporting device having an outer sleeve and an inner sleeve. A method of assembling such a support jack, in which a spindle nut is connected detachably to the inner sleeve by means of at least one translatory and one rotary joining movement or at least by means of two translatory joining movements.

Support jack

A semi-trailer landing gear, in particular to support trailers, with a support element which includes an outer sleeve and an inner sleeve and which can be displaced in a telescopic manner in relation to the height. The outer sleeve includes a securing flange which can be applied to a vehicle. The aim of the invention is to develop a semi-trailer landing gear which is economical to produce and can also withstand high loads. The aim is achieved by virtue of the fact that the outer sleeve and the securing flange are made of a single piece of flat steel by edge rolling.

Semi-trailer landing gear

A support jack, in particular for supporting semitrailers, includes a vertically telescopically displaceable supporting element having an outer sleeve, and an inner sleeve that can be vertically displaced in a telescopic fashion, each sleeve having a rectangular cross-section with four sidewalls. At least the inner sleeve has a wall plate joined to two adjacent side walls with welding seams that improve the bending stiffness of the support jack. The welding seams can be located inside or outside either of the sleeves. Such a support jack can be located on the lower side of any vehicle.

A support jack for supporting semitrailers including a vertically telescopically displaceable supporting device having an outer sleeve and an inner sleeve. A spindle nut has projections and contact elements for being positively detachably connected to the sleeves. The projections interact with openings of the inner sleeve for fixing the spindle nut in the direction of the longitudinal axis of the support jack. The contact elements interact with an inner side of the outer sleeve for fixing the spindle nut in the direction of rotation about the longitudinal axis. A method of assembling a support jack is also described, in which the spindle nut is connected detachably to the inner sleeve by at least one translatory and one rotary joining movement or at least two translatory joining movements.

A semitrailer landing gear, particularly for supporting trailers, including a supporting element, which can be telescopically displaced in the height thereof and which has an outer sleeve and an inner sleeve, the outer sleeve having a fastening flange for placing on a vehicle. The aim of the invention is to develop semitrailer landing gears with a reduced weight as well as with favorable manufacturing costs. To this end, the invention provides that at least one lateral wall of the outer sleeve and/or of the inner sleeve is provided with an angled wall section extending in an axial direction.

Semitrailer landing gear

The invention describes an arrangement of lubricating grease inside the housing of a gear unit with rotatable components, particularly the gear unit of a jack. It also describes a grease pouch for receiving lubricating grease and a method for lubricating the gear unit with lubricating grease. Since the gear units are often not transported in their installed position, oil that has separated from the lubricating grease may leak from any gearbox openings. Thus, one of the objects of the invention was to provide an arrangement of lubricating grease in the housing of a gear unit, which on the one hand provides lubrication of the gear unit so that it is ready for operation in its delivery condition and on the other hand effectively prevents the oil separated from the lubricating grease from leaking prior to initial startup. This object is attained by enclosing the lubricating grease within at least one grease pouch prior to initial startup of the gear unit. The at least one grease pouch is inserted into the housing of the gear unit so as to contact the components. Upon initial startup the at least one grease pouch is torn open by the action of the components and releases the lubricating grease.

Support winch with grease supply

An apparatus for supporting a trailer of a tractor semitrailer has a supporting element that is telescopically adjustable by way of a gear shifting mechanism having a gear input shaft running vertically onto a spindle. In this way, the supporting element has an especially compact construction and can be installed very easily. The gear shift also has a free floating gear between two shift positions and can be shifted very conveniently.

Apparatus for supporting the trailer of a tractor-semitrailer

The invention relates to a supporting device, which comprises a larger clearance for the spindle, whereby the foot receiving device should comprise a high level of stability. The foot-receiving device comprises a component, which occludes the inner sleeve. Said component comprises an opening for admitting the spindle, at least one bracing element located on the upper and/or bottom sides thereof, and two opposing bearing points for the support foot.

Supporting device

A support device for semi-trailers including a leg which has a receiving device, on its lower end. The support leg has a base element with a base plate, whereby the base element is fastened to the base receiving device by a fixing device. The base element is connected by a pivot bearing device with the support leg, whereby the pivot bearing device is located below the damping element. The compression of the damping element is therefore fully decoupled from the pivoting movement of the base element.

Support device

A landing gear assembly for a semitrailer includes a pair of legs that may be simultaneously raised or lowered by turning a single crank. Each of the legs is configured to be able to be mounted in either an inboard or outboard configuration. This is achieved by providing both sides of each leg with no protrusions that extend beyond the space provided in the mounting bracket and the mounting hole used to connect the landing gear to the semitrailer. The gear assembly of the landing gear includes a unique floor base that receives and supports the input shaft. A cover is used to support the input ends of the input shaft and the output shaft. The cover is connected to the input side of the upper tube of the leg and allows the gear assembly to be easily assembled within the perimeter of the upper leg.

Trailer landing gear

The invention relates to a support device for semi-trailers comprising a leg which has a receiving device, on its lower end. The support leg has a base element with a base plate, which is mounted by means of two vertical plates on the base receiving device so that it can move vertically and can pivot. Between the base plate and the base receiving device there is a damping element. To achieve an improved pivoting capability of the support base, whereby the damping element is subjected to a small deformation, the damping element is located on the underside of the base receiving device so that cannot pivot, and is supported on a curved plate which is fixed to the base plate and the contour of which is adapted to the pivoting movement of the base plate in relation to the supporting leg.

The invention relates to a support foot, which is equipped with a damping element and which exhibits an improved pivotability. The fixing element which is provided for pivotally fastening to a foot receiving device rests on the damping element or is fastened to the same, whereby the fixing element is held by a bracket which is fastened to the foot plate and which overlaps the fixing element. According to another embodiment, the fixing element is comprised of two vertical plates fastened to the foot plate at a distance from the damping element, whereby each plate comprises a vertically arranged, longitudinal hole or a round hole having a diameter larger than the diameter of the bearing element.
