WIPO Patent Application WO/2009/103241
Kind Code:
A1
Abstract:
A torsion bar vehicle suspension device, which includes a front torsion bar spring (3) and a rear torsion bar spring (11) respectively installed at front and rear suspensions of the vehicle. The opposite ends of the front and rear torsion bar springs in the same side are connected mutually by a connection mechanism (7, 8), and are connected with a vehicle frame (4) through a positioning device (6, 9). The connection mechanism (7, 8) is mounted between the front and rear torsion bar springs in the same side, so that a linkage relationship is established between the front and rear torsion bar springs. The device improves the oscillation situation of the vehicle when driving the vehicle on an uneven ground, and prevents the vehicle frame and vehicle body skeleton suffering from torsional force. As a result, the usage life of the vehicle is prolonged.
