Definitions
- the invention relates to a height-adjustable support for semi-trailer or the like or supporting device of a vehicle, in particular a semi-trailer or trailer.
- Such supports are mounted in pairs on the front of semi-trailers and can be telescoped in support or transport position.
- Such supports are known for example from EP 0 675 029 and EP 1 104 369 B2. These have over cranks drivable transmissions with a
- the mechanical complexity is still increased by spindle drives, storage parts, etc., which causes considerable manufacturing costs and, unfavorably, a high column weight.
- a motor unit is attached to the above supports per pair, which additionally required mounting and hedging means a further mechanical effort and thus an increase in weight.
- Today's semitrailers with air-sprung rear axle aggregates can also be used on the fifth wheel or on the front of a saddle when mounting or unhitching via the fifth wheel. Raise or lower trailer. A hoisting or lowering by means of semi-trailer supports is therefore not required. Instead, only the fastest possible load-free extension and retraction of the supports from the transport position to the support position and vice versa has the highest priority in practice.
- a support as a commercial vehicle component and mass-produced product should have the lowest possible weight and must be inexpensive to manufacture.
- the invention has for its object to provide a height-adjustable support or support device for semi-trailer which very quickly, i. With only a few turns of the crank or efficient power drive, and can be easily brought into their support position and also back to the transport position, the weight and construction cost is low and only requires low production costs.
- a supporting device of a vehicle comprising an outer tube which is designed to be fixedly mounted on the vehicle, an inner tube which is displaceably arranged in the outer tube in the insertion and extension direction Actuating means for displacing the inner tube between a transport position and an operating position, and engagement means, which is designed in a first operating state, set the inner tube in the operating position to the outer tube such that a displacement of the inner tube is prevented in the insertion direction.
- the engagement device can be brought into a second operating state, in which a displacement of the inner tube to the outer tube in the insertion and extension direction is made possible.
- the engagement direction is thus changeable or displaceable between a first and a second operating state.
- the engagement means comprises an engagement means, such as a latch, with an engagement portion, such as a ratchet tooth, adapted to engage an outer tube engagement portion.
- a plurality of outer tube engaging portions are provided, which are suitably formed in the form of a rack piece or in the form of embossed parts of the outer tube.
- the plurality of outer tube engaging portions are arranged in the insertion and extension directions so that a plurality of engaging portions can engage therein simultaneously and / or the operating position of the inner tube can be set in an operating range defined by the plurality of outer tube engaging portions.
- an engagement means can be provided which has a plurality of engagement regions which are arranged linearly and / or transversely thereto in the insertion and extension directions and which can engage in the plurality of outer tube engagement regions.
- a plurality of outer tube engaging portions may be provided, it is thus possible to fix the inner tube relative to the outer tube in various positions along the insertion and extension direction. These positions form the operating area.
- a plurality, preferably two, engagement means are provided, which are in particular designed to engage via their engagement regions in opposite outer tube engagement regions.
- the engagement means may thus act in opposite directions and thus engage in respective outer tube engaging portions formed in opposite walls of the outer tube.
- the engagement means on the inner tube is pivotally mounted about an axis or translationally transverse, in particular perpendicular, to the insertion and Ausfahrrich- direction.
- the engagement means may thus be arranged in particular substantially stationary relative to the inner tube and be mounted pivotably relative to the inner tube.
- the engagement means is arranged stationary to the inner tube, that this can not be displaced in the insertion and extension, but only transversely, in particular perpendicular to the insertion and extension direction is movable to engage in corresponding Vietnameserohr- engagement regions.
- the engagement device in particular its predominant part - disposed within the inner tube.
- the engagement device can be configured such that only its engagement means projects through and over the inner tube during operation.
- the engagement means comprises a biasing means, such as a tension or compression spring, via which the engagement means is biased in the direction of the first operating state.
- a biasing means such as a tension or compression spring
- the engaging device is operatively connected to the actuating device such that it can be actuated or controlled via the actuating device.
- the engagement device upon actuation of the actuating device, the engagement device is brought into a second operating state and / or held and preferably in the presence of a force directed in the insertion direction on the Inner tube brought the engagement device in the first operating state.
- the directed in the insertion direction force or ground contact force is such that the inner tube is not moved further in the extension direction. This condition occurs when the distal end of the inner tube rests on the ground.
- the actuating device has an active / driven part, which is preferably operatively connected via a preferably flexible tension element, such as a rope, with the preferably rotationally or pivotably mounted engagement means, in particular the detent pawl.
- the engagement means in particular its engagement region, in this case is expediently connected to the tension element and can be brought out of engagement therewith with the outer tube and as a result the inner tube can be pulled up or lowered.
- the part of the tension element oriented along the insertion and extension direction is expediently shortened or lengthened when the actuating device is actuated.
- the actuating device has a drive shaft in order to actuate the active / driven part.
- the active / driven part preferably has a locking part region for a load pressure brake, a winding region for the tension element and preferably a driven spigot.
- the active / driven part has a locking portion in a winding region for the tension element, which is no longer covered by the tension element after complete unwinding of the tension element, so that a locking member can engage with the locking portion and another rotation the active / driven part prevented in the unwinding.
- Such an embodiment is particularly advantageous because the support is extended by a rotation of the active / driven part in the unwinding direction and, in the case of a further rotation without such a preferred embodiment, although the column foot already rests on the ground, it is unintentionally reopened.
- the winding region has a blocking portion, which may be formed as a partial recess into which, when the tension element is completely unwound, advantageously engages a locking member formed as a locking pawl and blocked in unwound tension element further rotation in the unwinding.
- the locking member may advantageously be acted upon by a spring.
- a preferably flexible tension member such as a rope
- the support device further comprises a display device which is designed to indicate the operating state of the engagement device.
- a display device which is designed to indicate the operating state of the engagement device.
- a signal pin or the like protrudes beyond the outer wall of the outer tube.
- this expediently has a vertical elongated hole oriented in the insertion / extension direction, through which the display device or the signal pin can pass.
- the outer tube is provided in at least one side region with vertically offset outer tube engagement areas or latching gaps, in this case a movable mounted in the inner tube engagement means or latching element and engage in a relative movement of the inner tube to the outer tube, so that the support in the support position their function fulfilling the load on the floor the abolishes.
- the engagement means or latching element is first disengaged via a flexible tension element fastened to the engagement means or latching element, and the inner tube is raised or lowered as a result. This is a structurally simple and easy to use handling.
- the rack piece can be worked out in the usual way from a semifinished product corresponding to its cross section, or, to save weight, it can be a thinner flat material which is shaped like a rack.
- latching element is preferably a latch which has at least one tooth provided, for which also parts, such as displaceable bolts, etc. are conceivable.
- a rope is preferred, but it may also be a band or the like.
- the vertical area of the cable fastened to the latching pawl is shortened simply by winding in order to ventilate the latching pawl and, as a consequence, to draw in the inner tube.
- the inner tube is lowered, ie extended.
- a winding area is provided around the axis of a shaft strand.
- the shaft train consists of a drive shaft to be driven by a hand crank, for example, and an active / driven part.
- the drive shaft and the active / driven part are partially configured so that they are parts of a load pressure brake and at the same time serve to connect with each other.
- the load pressure brake allows a controlled retraction and extension of the inner tube and in every position a secure holding of the load.
- the load is to be understood as meaning only the weight of the mass of the inner tube and a foot attached thereto.
- only one borrowed, arranged in the prop to be propelled load pressure brake assumes the holding function for both.
- There is an economic advantage because in the mitangetriebenen support only a winding area for the rope is required. It is also moderately favorable in terms of production if the active / driven part is fitted in one piece. ckiger design the winding area of the rope, as well as the Sperrteilbreich the load pressure brake and a driven pin has.
- the tensile or Nachlassvorgang of the rope for releasing the pawl and retraction and extension of the inner tube by a pneumatic differential cylinder, motor spindle drive or the like is exercised.
- a deflection roller for the rope is provided at the free end of the downward-pointing piston rod of a preferred pneumatic cylinder, by their downward or upward displacement, the respective desired movement of the rope.
- the rack pieces described above may be mounted in the outer portion of the outer tube, which preferably has a square cross-section, in the wall portion, that the teeth do not project inside, and the inner tube may be square. A preferred attachment of a rack piece is achieved when its teeth protrude in the outer tube on the inner wall.
- the rack piece is proposed on the inner tube to provide a push-in / export direction or longitudinal direction extending recessed wall portion whose width exceeds the width of the rack piece and whose depth is greater than the projection of the projecting into the outer tube teeth.
- the rear wall portion of the outer tube is to be used, because at the engaging there latching a signal pin can attach such that it can conveniently make the on or off state of the latch the driver visible on the front of the support.
- the pawl is pressurized by means of a spring, which is biased against the inner tube, which contributes together with the conditional by the weight of the latch action to secure engagement in the tooth gaps of the rack piece.
- the spring is placed on a stop, which is preferably attached to the latch.
- the train of the rope initially causes disengagement of the latch, wherein the stop abuts the inner tube, and causes the entrainment of the inner tube upwards. When let, ie extension of the inner tube, the stop in the inner tube in abutment and the weight of the inner tube and the foot is lowered controlled until the foot touches the ground.
