Steering trapezoidal arm for automobile

Abstract

The invention relates to a steering trapezoidal arm for automobiles, which comprises a body. The two sides of the body are symmetrically provided with transverse reinforcing ribs and longitudinal reinforcing ribs. A hole seat 1 is symmetrically arranged on both sides, and a fixing hole is arranged on the hole seat 1, and the transverse reinforcing rib is fixedly connected to the hole seat 1, and a bearing 1 is arranged in the fixing holes, and the cross arm 21 There is a hole seat 2 at the end, and a connection hole is provided on the hole seat 2, and a bearing 2 is arranged in the connection hole, and the bearing 1 and the bearing 2 are movably connected with the fixing hole and the connection hole, and are provided with transverse reinforcement Ribs and longitudinal ribs can not only increase the mechanical strength of the steering trapezoidal arm, but also reduce the weight of the steering trapezoidal arm and reduce the weight of the car. By providing hole seat 1 and hole seat 2, the two ends of the fixing hole and the connecting hole can be aligned with each other. The steering trapezoidal arm forms a certain distance to prevent friction between the mounting part and the first cross arm and the second cross arm.

[0002] With the continuous improvement of the speed of the expressway network, people pay more attention to the driving stability and driving safety of the vehicle, so that the non-independent suspension vehicles can no longer meet the requirements of driving safety and handling stability. , the use of independent suspension on vehicles has become a development trend. Each wheel of an independent suspension vehicle moves independently relative to the frame, and its steering bridge is disconnected, so the steering trapezoid in the steering mechanism must also be able to Divided into two or three sections, the design of the disconnection point needs to be completed by considering the requirements of the vehicle suspension beating and the vehicle steering requirements. The selection of the disconnection point is related to whether the left and right steering wheels can turn around the same instantaneous center, so that the tires Causes wear and tear, and is also related to whether it interferes with suspension jumps and causes movement to interfere with steering, resulting in excessive steering characteristics of the vehicle, affecting vehicle handling stability and driving safety, and the steering knuckle arm is affected by the overall layout of the vehicle. Its design space It is also relatively small. To sum up, the above points make it difficult to design the whole disconnected trapezoid, which greatly increases the difficulty in the front axle layout of independent suspension vehicles, and to a certain extent also causes tire wear, poor handling stability, and even some The driving safety cannot be guaranteed. The general trapezoidal steering arm is a solid structure, and the connecting hole is in direct contact with the mounting part, resulting in increased friction, long service life and serious wear, which affects the service life of the trapezoidal steering arm.
