Patent number: 10807222Abstract: A dismounting tool for disengaging ball joint connections on suspension and steering assemblies is disclosed. The dismounting tool comprises an actuator having two receiving portions, where the actuator is operable to force two receiving portions towards each other along an actuation axis. The dismounting tool further comprises a first tool member having an anvil portion with an engaging surface and a second tool member having a bifurcated portion with a supporting surface. Each of the tool members comprises a through hole and are detachably mounted to a respective receiving portion such that the through holes are arranged coaxially about the actuation axis such that the engaging surface faces the supporting surface. The actuator is, upon actuation, configured to move the two tool members towards each other along the actuation axis.Type: GrantFiled: June 28, 2018Date of Patent: October 20, 2020Assignee: WALLMEK I KUNGÄLV ABInventors: Niklas Wallman, Martin Hasselskog, Sten Johansson

Patent number: 10393184Abstract: A mounting tool and a method for mounting a wheel bearing assembly, having an inner ring flange and an outer bearing ring, into a bearing seat of an axle body of a vehicle are disclosed. The mounting tool includes a supporting member, two L-shaped holding members, which can be fastened at various positions along the supporting member, and at least one securing means for fastening the L-shaped holding members to the supporting member. The holding members each have a foot section with a recess, the foot sections being insertable in an intermediate space between the inner ring flange and the outer bearing ring in order to engage the outer bearing ring. Each recess has a shape configured to apply an evenly distributed pressure to outer bearing rings of several different dimensions. Hereby a flexible and versatile mounting tool is provided.Type: GrantFiled: July 7, 2016Date of Patent: August 27, 2019Assignee: WALLMEK I KUNGÄLV ABInventors: Niklas Wallman, Sten Johansson, Martin Hasselskog
