Description

Toe-in adjusting rod and suspension assembly with toe-in adjusting rod Technical Field The invention relates to the field of suspension systems, in particular to a front beam adjusting rod and a suspension assembly with the front beam adjusting rod. Background Most of structures playing a role in adjusting a front beam in the current market are rear upper control arms or rear lower control arms, the main structure of the structure is that a stamping part and a press-fit sleeve are welded, and compared with an aluminum alloy material structure, the structure has the disadvantages of heavy weight, unstable manufacturing process and large welding deformation, and finally the assembly efficiency and reworking probability of the whole automobile are influenced. And in recent years, the economic and automobile industries of China rapidly develop, and domestic automobile competition becomes increasingly white and hot. With the increasing quality feeling, quality requirement and performance requirement of people on automobiles, lightweight materials and optimized structural designs generated by fortune are put into the spotlight of the industry. The front beam adjusting rod plays a role in connecting the auxiliary frame and the steering knuckle and adjusting the front beam in the whole vehicle. As an important structural member of the chassis of the whole vehicle, the chassis not only carries important performance indexes, but also meets the arrangement space requirement of the whole vehicle. The traditional rear suspension front beam adjusting rod adopts a sheet metal stamping part, a basin-shaped structural form is realized through a welding process, and along with the fact that vehicles are bigger, particularly new energy vehicles rise recently, the weight of the whole vehicle is generally far greater than that of a traditional fuel vehicle type due to the influence of the weight of a battery. The chassis structural member strength performance index brought by the increase of the vehicle weight also causes the water-swelling ship to be high, and the volume and the weight of the structural member are continuously increased to meet the performance requirement, so that sufficient space cannot be provided for the battery arrangement. In addition, the existing toe-in adjusting lever is generally of a two-stage structure. For example, patent 201410223659.3-a disclosure of an automotive toe-in adjustment lever. Although the adjustment of inclination can be realized to traditional two-section formula toe-in adjusting pole, overall structure is comparatively complicated, simultaneously because be sectional type structure, self intensity is not enough. And the existing front beam adjusting rod has more modules and more assembly procedures. In order to improve or solve at least one of the above problems, it is necessary to optimally design the existing toe-in adjusting lever. Disclosure of Invention The invention aims to provide an integral toe-in adjusting rod structure. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The front beam adjusting rod comprises a front beam rod body, wherein one end of the front beam rod body is provided with a first connecting mechanism, and the other end of the front beam rod body is provided with a second connecting mechanism; the first connecting mechanism comprises a connecting ring arranged on the front beam rod body, wherein the connecting ring is provided with a first assembly hole; The second connecting mechanism comprises two assembly plates which are distributed on the front beam rod body at intervals, and each assembly plate is provided with at least one second assembly hole.
