Description
Technical Field
The invention relates to a bracket, in particular to a steering system bracket based on an FSAE monocoque body.
Background
In the development process of the equation series events of college students, due to the pursuit of each motorcade on the light weight of the whole vehicle and the high-performance structure of the vehicle frame, a monocoque vehicle body technology appears. The monomer shell adopts a composite material structure, and a carbon cloth honeycomb aluminum sandwich structure is used as a vehicle body structure of the university formula racing vehicle to replace a vehicle frame structure, so that the torsional rigidity of the vehicle body is increased, and the weight of the whole vehicle with the vehicle frame is reduced to a certain extent. Monocoque body construction is currently a technology of interest to most fleets of vehicles.
In previous frame designs, the steering system was attached to the front ring of the frame by a bracket. In the frame manufacturing process, in order to ensure the precision of a frame finished product, the whole frame fixture can be manufactured in advance, the position of a front ring is ensured to be accurate, and the steering system cannot be greatly influenced. However, in the monocoque body structure, due to the influence of various aspects such as prepreg, adhesive film, honeycomb aluminum and the like and the manufacturing process, certain errors can be caused in the monocoque product and the design. In the design process of a steering system in the prior art, most fleets can directly design the angle of the bracket according to the design angle of the steering system, the geometric relationship of the steering system cannot be changed, namely the angle and the structure of the whole system cannot be changed, and meanwhile, because the point position of the steering bracket is positioned on the single shell and the single shell needs corresponding embedded parts according to the strength requirement, the point position of the bracket cannot be changed, so that the traditional rod bracket cannot be installed directly.

The purpose of the invention is as follows: the invention aims to provide a steering system support based on an FSAE monocoque body, which solves the problem of difficult assembly of a steering system.
The technical scheme is as follows: the steering system comprises a vehicle body support and a connecting rod support, wherein the vehicle body support is connected with the connecting rod support in an inserting mode, the vehicle body support is connected with a single shell vehicle body, the connecting rod support is connected with a steering system, the vehicle body support comprises a bottom plate, two bosses are fixed on the bottom plate, the connecting rod support is of a cylindrical structure, a protrusion is arranged on the outer side of the cylindrical structure along the axis direction of the cylindrical structure, and the bosses are inserted on the protrusion.
The connecting rod bracket is sleeved on a connecting rod of the steering system.
A deep groove ball bearing is arranged between the connecting rod support and the connecting rod, so that the normal function of the steering system is ensured.
The length of the cylindrical structure of the connecting rod bracket is at least 30 mm.
And ribs are arranged between the cylindrical structure and the bulges to be used as reinforcing structures.
The boss adopts a right-angled trapezoid structure.
The lug boss and the bulge are in transition fit.
The bottom plate is provided with bolt holes, and the vehicle body support is connected with the vehicle body through the bolts.
The car body bracket and the connecting rod bracket are both made of aluminum alloy.
Has the advantages that: the invention can avoid the influence of the monocoque body on the steering system to the maximum extent, and the influence is concentrated on the bracket and finally eliminated, so that the steering system is easy to install, the reworking of parts is avoided, and the loss of manpower and financial resources is avoided; the problem of because of the monocoque automobile body error leads to the steering system installation difficulty is solved, made things convenient for steering system's installation and fixed to a very big extent, dwindled installation time to within half an hour.
