Problems solved by technology

This can lead to an undesired increase in size and weight
Another disadvantage of some known arrangements is that in use undesired axial movement of the stabilizer bar may occur which may interfere with normal operation of the stabilizer bar
Additionally, many stabilizer bar designs have relatively large dimensions, making it difficult to accommodate the stabilizer bar on the vehicle and comply with ground clearance constraints on the vehicle, especially when used with construction vehicles

Embodiment Construction

[0032] Refer to the attached Figure 2 to Figure 4 , shows a stabilizer bar 10 comprising an elongated shaft 12 mounted via a bracket 14 to an axle 16 of a truck 17 (only a small portion of the truck 17 is visible in the figure). In the arrangement shown, the shaft 12 is hollow along its entire length and is preferably in the form of a composite material. It will be appreciated that considerable weight savings can be achieved compared to arrangements comprising solid steel shafts or the like. Although in the arrangement shown, the shaft 12 is hollow throughout its length, it will be appreciated that this need not be the case, but instead, the shaft 12 may be of solid form or only near its ends. Hollow arrangements are also possible and such arrangements do not depart from the scope of the present invention.

[0033] Such as Figure 4 As best seen in FIG. 1 , within each end of the shaft 12 is a bearing assembly 18 secured to the associated bracket 14 in a manner that permit...

Abstract

The invention relates to a stabilizer bar (10) for use with the suspension of a vehicle such as a truck. The stabilizer bar (10) comprises a shaft (12) supported by bearings (18), at or near each end of the shaft (12) provided is a crank portion, for example in the form of a crank arm (30), each crank portion having a connecting points (32) for connection in use to a respective linkage member (34), wherein each connection point (32) is substantially aligned with the axis of a respective one of the bearings (18) relative to said shaft (12). The invention also relates to a vehicle comprising such a stabilizer bar (10) and a roll stabilization method using such a stabilizer bar (10).

Description

technical field [0001] The present invention relates to a stabilizer bar for a vehicle, and in particular, to a stabilizer bar suitable for use, for example, in a suspension associated with a front or rear axle of a vehicle such as a heavy truck, the stabilizer bar being The lever is operable to control or limit rolling motion of the vehicle chassis or body. The invention also relates to a vehicle comprising such a stabilizer bar and a stabilization method using such a stabilizer bar. [0002] The invention is applicable to heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described in relation to a truck-related suspension, the invention is not limited to this particular type of vehicle, but may also be used in other vehicles or other applications. For example, it can be applied to suspensions of cabs, etc. Background technique [0003] Many designs of stabilizer bars suitable for this type of application are known. figure 1...
