Abstract
Description
[0001] The invention relates to a device that significantly simplifies wheel changing on passenger cars and can be operated by one person.
[0002] The strenuous lifting and difficult fitting of the vehicle wheel onto the wheel bolts of the wheel hub is eliminated.
[0003] It is already known that devices for changing wheels exist, but these have some drawbacks. These devices are more cumbersome, heavier, and require more physical effort to operate.
[0004] Utility model DE 20 2008 007 539 U1 discloses a wheel mounting and adjustment trolley for car and truck wheels, wherein a wheel to be mounted on a vehicle axle can be positioned in a vertical, horizontal and axial direction.
[0005] Utility model DE 80 34 671 U1 discloses a wheel mounting trolley for truck wheels, which is designed similarly to a hand truck.
[0006] The invention aims to at least partially compensate for or eliminate the disadvantages caused by the prior art.
[0007] The invention essentially consists of two joined parts. One part is designed as a lever arm with rollers (4 and 5) and the second part as a receiving device (1) for a vehicle wheel.
[0008] The invention consists mainly of light metal and is therefore very light (approx. 1.2 kg). The device measures approximately 25 x 20 x 10 cm, and the lever arm can be extended by means of a simple plug connection (5). The space-saving device is lightweight, rustproof, maintenance-free, and therefore also environmentally friendly.
[0009] Thus, technological progress is clearly evident.
[0010] Cost-effective, factory-based production of the device is not a problem because its parts consist of commercially available materials.
[0011] The device has 4 rollers (2, 3 and 4) mounted on both the underside and the top. These rollers are used to move the device and the wheel, which is positioned vertically on the receiving device, in several directions by hand.
[0012] The rollers on the underside are smaller at the front (2) than at the rear (4). This size difference serves to balance the wheel, which is positioned vertically on the device. This is because passenger car wheels tend to tilt outwards. Here, too, a significant improvement compared to previous devices is evident.
[0013] The device has a two-armed lever arm (5) which is raised at approximately 40° by a bend in its lower part. A roller (4) is located at each bend. The lever arm serves as a lever arm and also for pushing or pulling the device, representing a further technical advancement.
[0014] The bracket is stabilized at the plug connection (5) by a cross connection (6).
[0015] The clamping bracket (8) in the center of the mounting device serves to keep the mounting device as horizontal as possible when the bracket arm is fully depressed. The lifting height of the mounting device is approximately 7 cm.
[0016] When removing a vehicle wheel, the device is only pushed under the jacked-up wheel until the upper 4 rollers (3) serve as support points.
[0017] It is important that the vehicle is only jacked up as far as absolutely necessary, i.e., the device should be slid under the tire tread with as little space as possible. After loosening the wheel nuts, the wheel slides vertically onto the device (1) by gently pushing or shaking the support arm. The device, along with the vehicle wheel, can then be pulled away. The wheel to be mounted is placed on the device and pushed together as close as possible to the wheel hub.
[0018] By rotating the wheel on the device, the rim holes are aligned with the wheel bolts. Then, using the device, the wheel is pushed onto the bolts and secured with the wheel nuts.
Claims
[1] Device for mounting and / or dismounting vehicle wheels, comprising a receiving device (1) for the vehicle wheel and a lever arm (10), wherein the lever arm is movably arranged, characterized by , that the lever arm (10) is rotatably mounted on the underside of the receiving device (1), wherein the lever arm (10) exerts a torque on the vehicle wheel by means of a support on the side of the receiving device facing the lever arm (10). [2] Device according to claim 1, wherein the receiving device (1) has at least one axle for receiving rollers (2) which are designed to position the receiving device (1) under the vehicle wheel. [3] Device according to one of the preceding claims, wherein the receiving device (1) has two axes for receiving rollers (2) which are designed to position the receiving device under the vehicle wheel. [4] Device according to one of the preceding claims, wherein the receiving device has at least one axle for receiving rollers (3) which are designed to rotate the vehicle wheel. [5] Device according to one of the preceding claims, wherein the receiving device has two axes for receiving rollers (3) which are designed to rotate the vehicle wheel. [6] Device according to claim 4 or claim 5, wherein the positioning axes are arranged substantially perpendicular to the roll axes. [7] Device according to any one of the preceding claims, characterized by , that the front rollers (2) on the underside of the receiving device are smaller than the rollers (4) on the lever arm in order to compensate for the lateral tilt of the vehicle wheel. [8] Device according to claim 7, characterized by , that the vehicle wheel can stand freely on the receiving device (1). [9] Device according to any one of the preceding claims, characterized by , that a clamping bracket (9) is provided under the receiving device, which extends from the lever arm (10) to the side of the receiving device (1) facing away from the lever arm.
