Watt connecting rod installation structure

Abstract

A watt connecting rod installation structure comprises a coupled lever horizontally lying above a torsion beam. The middle portion of the coupled lever is hinged to the torsion beam through a fixed shaft fixed to the upper side of the torsion beam. Two horizontally-arranged push-pull rods are hinged to the two ends of the coupled lever. The other ends of the two push-pull rods are hinged to the portions, on the two sides, of an automobile body. Due to the fact that the structure is installed at the upper end of the torsion beam and occupies the horizontal space above the torsion beam, the longitudinal space of a chassis does not need to be occupied, the structure can be suitable for a vehicle model which is provided with a low base and cannot reserve a longitudinal space for a traditionalwatt connecting rod, the application range of the structure is wider, and the structure at the bottom of an automobile is more compact. Due to the fact that the two ends of each push-pull rod are directly connected to the automobile body, an axial support is additionally provided for each of the two sides equivalently, and connection is more stable.

Description

technical field [0001] The invention relates to a connection structure between an automobile body and a torsion beam, in particular to a Watt connecting rod installation structure. technical background [0002] Such as figure 1 As shown, in the current design of the rear torsion beam, the Watt link is a rod added to the left and right of the rear suspension. One end of the rod is installed at the end of the body and moves vertically with the body. The two rods 101 are connected by a coupling device 102, and the coupling device is connected to the torsion beam 103. The two rods interact with the coupling device to limit the range of motion of each other, so that the compression of the suspension on both sides can be reduced. and stretch. The compression and expansion ranges of the suspension 104 are made. The force on both sides of the suspension is more even, and the vehicle roll will be significantly reduced, which greatly improves the stability of the vehicle body, espe...

Problems solved by technology

[0004] However, due to the arrangement of the Watt connecting rod, a large longitudinal space needs to be reserved at the bottom of the car, which makes the bottom structure of the car not compact enough, which runs counter to the expectations and requirements of market consumers.

Also because the Watt connecting rod has high requirements on the longitudinal space at the bottom of the car, it is difficult to apply it to models with a low chassis
