Patent number: 11034399Abstract: The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.Type: GrantFiled: May 9, 2017Date of Patent: June 15, 2021Assignee: BAE Systems Hägglunds AktiebolagInventor: Anders Bodin

Patent number: 7597411Abstract: The invention relates to a device for operating a track tension wheel on a tracked vehicle. The device comprises two operating cylinders, a pivoting cylinder (38, 48) for pivoting a tension wheel arm (10) that carries a tension wheel, and a tensioning cylinder (28, 30) for changing the distance between the center (25) of the tension wheel and the center of rotation (12) of the tension wheel arm. The tensioning cylinder (28, 30) is pivotally connected to a pivoting link arm (36), which link arm is arranged to be stationary in a first phase of a pivoting upward movement of the tension wheel arm (10) from a lowered position and to pivot around its connection to the link arm (36). In a second phase of the upward pivoting movement, a lug (50) on the tension wheel arm (10) is arranged to engage with the link arm (36) to cause the tensioning cylinder (28, 30) to be pivoted around the connection of the link arm (36) to the attachment (18) during a continued upward pivoting movement of the tension wheel arm (10).Type: GrantFiled: January 30, 2007Date of Patent: October 6, 2009Assignee: BAE Systems Hägglunds AktiebolagInventors: Anders Bodin, Mats Vigren

Patent number: 7093914Abstract: Device for manoeuvring a tension wheel in a chassis of a tracked vehicle, in which the tension wheel is rotatably mounted on a telescopic rocker arm (12). The rocker arm can, on the one hand, be lengthened and shortened by a first hydraulic cylinder and, on the other hand, swivelled about a transverse axis (14) by a second hydraulic cylinder for the purpose of raising and lowering the tension wheel. The first hydraulic cylinder is designed to act upon a lever arm (58) of a sleeve (54) rotatable in a hub part (20) of an inner part (18) of the rocker arm (12), which sleeve has an eccentrically mounted crank pin (52) which is hinge-connected to an outer part (22) of the rocker arm for the purpose of displacing the latter relative to the inner arm part, in the event of a mutual rotation motion between the sleeve (54) and the hub part (20) of the inner rocker arm part, in such a way that the rocker arm is lengthened upon a downward swivel motion of the arm and the tension wheel.Type: GrantFiled: April 7, 2004Date of Patent: August 22, 2006Assignee: BAE Systems Hagglunds AktiebolagInventors: Claes Eriksson, Anders Bodin
