Embodiment Construction
[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0020] see figure 1 , figure 2 , image 3 , taking the lower swing arm as an example, in this embodiment, the multifunctional adjustment mechanism applied to the double wishbone independent suspension is installed at the hinge of the lower swing arm 2 and the sub-frame swing arm connecting plate 3, and the sub-frame swing arm connecting plate There are two 3, extending downwards from the sub-frame 1, which are respectively arranged on the outer sides of the lower swing arm 2. The lower swing arm 2 is provided with through holes, and the swing arm connecting plate 3 of the sub-frame is provided with waist-shaped holes at corresponding positions.
[0021] Corresponding to the connecting plate 3 of the swing arm of the sub-frame, the multi-funct...

A multifunctional adjusting mechanism applied to double-wishbone independent suspensions is mounted at the articulating joint between a lower swing arm and subframe and swing arm connecting plates and comprises at least one adjustment assembly, each adjusting assembly comprises a fixed parallel channel holder and an eccentric washer, the fixed parallel channel holders are fixed on the outer sides of the subframe and swing arm connecting plates, the eccentric washers are fixed in the channels of the fixed parallel channel holders, the fixed parallel channel holders are provided with slotted holes, the eccentric washers are provided with eccentric holes, fixing screws run through the eccentric holes, the slotted holes, the lower swing arm and the subframe and swing arm connecting plates to be fixedly connected with nuts at the other ends, and when rotated, the eccentric washers can drive the fixing screws to horizontally move in the slotted holes by means of the eccentric holes of the eccentric washers, so that the lower swing arm is driven to horizontally shift relative to the subframe and swing arm connecting plates. As long as the eccentric washers are adjusted by a certain angle, the inner point of the lower swing arm can move along the Y direction, i.e., the kingpin inclination angle is changed; the structure is simple, the cost is low, mounting is convenient, and the stability is good.
Description
technical field [0001] The invention relates to the field of automobile independent suspensions, in particular to a multifunctional adjustment mechanism applied to double wishbone independent suspensions. Background technique [0002] For the design and adjustment of independent suspension, how to control the wheel alignment parameters and wheelbase within the involved range and enhance its adaptability has always been an important issue. And wheel alignment parameters including kingpin inclination angle, kingpin caster angle and wheel camber angle are also important guarantees for controlling the attitude of the vehicle. [0003] The wheel camber and kingpin inclination play a very important role in the lateral force of the vehicle, and the wheelbase is a key design index that directly affects the handling of the vehicle; while the wheel camber, kingpin inclination and wheelbase are important for mass production. The fixed models produced must be controlled within a precis...
