[0027]The first elastic member 10 is provided so as to be able to absorb displacement due to stress applied to the bushing arrangement in the vehicle transverse, longitudinal and vertical directions. Preferably, the first elastic member has appropriate rigidity in the vertical direction and softness in the transverse and longitudinal directions. The bushing arrangement 6a also comprises a second bushing element. The second bushing element comprises a second elastic element 13 and a second rigid sleeve 12 . The second rigid sleeve 12 is arranged radially spaced apart from the first rigid sleeve 11 and has a radially inner axial face 16 and a radially outer axial face 17 . The second elastic element 13 is arranged in the space between the first and the second rigid sleeve 11 , 12 . Alternatively, the second bushing element may be arranged somewhere between the first rigid sleeve 11 and the core 9, so as to be in a position radially closer to the central axis 9a of the core.

Abstract

A bushing arrangement for the connection between a drivers' cab and the chassis of the vehicle. The anti roll bar comprises a torsion bear and two link arms. Each link arm has a first end portion connected to the torsion bar and a second end portion connected to a core (9) by a first bushing element. The first bushing element comprises a first rigid sleeve (11) arranged concentric to the core and a first elastic element (10) positioned between the first rigid sleeve and. the core. The bushing arrangement further includes a second bushing element arranged concentric at a radially outer or inner position relative to the first bushing element. The second bushing element comprises a second rigid sleeve (12) and at least a second elastic element (13) wherein at least a portion of the radially inner surface of the second rigid sleeve is arranged in contact with the radially outer surface of the second elastic element. The second elastic element is more elastic than the first elastic element. The second bushing element is provided with at least one adjustable stop arrangement comprising one stop portion (12a) included in the second bushing element.

Description

technical field [0001] The present invention relates to a bushing arrangement providing a connection between a cab and an anti-roll bar connected to the chassis of a vehicle. Background technique [0002] The cabin is exposed to forces such as vehicle rolling, vibrations from uneven road surfaces, and forces applied to the vehicle when cornering and braking. The anti-roll bar has a bushing arrangement to absorb vibration and transmit force. The elasticity of the bushing means determines the absorption capacity of the bushing means. The highly elastic bushing device satisfies the need for absorbing vibration or displacement, thereby providing vibration damping for the cab, while the highly rigid bushing device provides better contact with the road surface and provides better feedback to the driver. Furthermore, the bushing arrangement can be made flexible in some directions of the vehicle and stiff in other directions of the vehicle. [0003] WO03 / 062034 and EP525435 discl...
