Wheel-clamping device for a wheel-service-machine and method for reversibly clamping a wheel on a wheel-clamping device for a wheel-service-machine

Abstract

The present invention concerns a wheel-clamping device for wheels on wheel-service-machines with only one drive unit and further a method for clamping wheels on a wheel-clamping device of wheel-service-machines with only one drive unit. The innovative wheel-clamping device for a wheel-service-machine according to the present invention comprises a frame 20 having a through-opening 22, and a spindle 30 being rotatably supported in the through-opening 22. Further, the spindle 30 has a through-hole 32 with a mounting-side end 30b and a driving-side end 30a, which is connectable to a drive means which is provided for a rotary movement for the spindle 30, wherein the spindle 30 has an external thread 34 on an external circumferential portion. Moreover, the wheel-clamping device comprises a sleeve 50 with a turntable 58 for the wheel to be clamped, wherein the sleeve 50 has an internal thread portion 52 which is in threaded engagement with the external thread-portion 34 of the spindle 30. Furthermore, a stopping or holding means 70 is able to temporarily hold the sleeve 50, and a clamping means 60 for the temporarily fixation of a fixing element 40 which is inserted through the mounting-side end 30b, to the spindle 30 is also provided in the innovative wheel-clamping device.

Description

technical field [0001] The invention relates to a wheel clamping device for a wheel on a turntable of a wheel repair machine having only one drive unit, and to a device for clamping a wheel on a wheel clamping device of a wheel repair machine having only one drive unit method. Background technique [0002] From EP patent 2110270 is known a wheel mounting device to which the rim of a wheel of a motor vehicle can be fixed. The rim may be rigidly connected to the wheel mounting arrangement. Furthermore, the rim may be centered on the central axis of the wheel fixing tool. [0003] It is also known from US patent 5244029 to use a cone to fix and center a motor vehicle wheel on a stationary flange. Said cone is hand-tightened around a hollow externally threaded fixed shaft, projecting on the flange on which the wheel is arranged. [0004] In the known devices and methods briefly described above, the rim of the tire can be fixed to the turntable by means of additional actuatin...

AI Technical Summary

Problems solved by technology

The use of manual actuators for the adjustment of the rim on the turntable does not carry any increased risk of machine failure, but the process of adjustment is more time consuming than the automatic process

Also, the installation of the wheel on a wheel repair machine by hand is not user friendly, especially when a large number of wheels need to be repaired, which means installation, balancing, etc.
