AI Technical Summary

Technical Problem

Existing methods for leveling motor homes and cars are cumbersome and require the vehicle to be moved, failing to account for wheel suspension rebound during tire lifting.

Method used

A device using a support arm, chain, and hydraulic jack to lift the tire directly, eliminating the need for vehicle movement and accounting for suspension rebound.

Benefits of technology

Enables easy, quick, and convenient leveling of vehicles without considering wheel suspension rebound, utilizing a commercially available electrohydraulic jack.

Abstract

Lifting device for vehicle tires and a jack for lifting vehicle axles without any rebound, e.g. for leveling caravans. Characterized in that the device consists of a support arm (1) which has a vehicle jacking plate (3) on the underside, a support chain (2) covered with a protective hose is attached to the left and right sides of the support arm, two tire pressure plates (4) are attached for torque absorption, a belt (5) attached to the support chain with spring hooks (tarpaulin hooks) for positioning the support chain.

Description

The apparatus is suitable for the purpose of leveling motor homes and cars easily, conveniently and quickly, and the vehicle does not need to be moved.By means of this device, the tire attached to the axle is directly lifted. As a result, no rebound travel of the wheel suspension is to be taken into account during leveling.The leveling is performed by means of the on-board jack.Commercially available electrohydraulic 12V trucks are convenient.Leveling Operation:The support arm of the device is placed parallel to the tire, resting against it, in front of the tire and aligned center to center.The carrying chain is then thrown with flywheel (on the ground) around the rear of the tire.The chain end, which is now visible on the other tire side, is fastened to the support arm on the other side with the aid of a screw and star-grip nut.Raise the support arm and place the lifting cylinder of the lifting arm under the lifting surface of the support arm. The jack should be placed as close to the tire as possible.Push the load-bearing chain upward on the left and right insides of the tire.Now pull the auxiliary belt from the tire rear slightly diagonally over the upper tire center forwards to the support arm and hang the spring hook as short as possible on the hook-in chain of the support arm.Check that the load-bearing chain bears only against the tire and not against parts of the brake system. Thus, the apparatus is installed and the lifting operation by means of the jack can startNamelist1 Support arm 2 Support chain 3 Protective tube 4 Color markings 5 Jack receiving plate 6 Non-slip support 7 Stop strip 8 Tire contact plates 9 Auxiliary belt 10 Tensioning hook 11 Hook-in chain 12 Belt fastening 13 Fastening screws
