Steering pair placed on double-wishbone independent suspension and its automobile

Abstract

The invention relates to a steering pair placed on a double-wishbone independent suspension and a car provided with the same. The steering pair comprises a steering gear, an auxiliary frame, an upperswing arm rotating shaft, an upper swing arm, an E-shaped support, an upper rotating shaft, a thrust bearing, a knuckle, a tie rod, a lower swing arm, a front camshaft, a rear camshaft, a lower rotating shaft, an upper bushing and a lower bushing. The upper swing arm is connected with the E-shaped support, the E-shaped support is rotationally connected with the knuckle through the upper rotating shaft, the E-shaped support is rotationally connected with the lower end of the knuckle through the lower rotating shaft at the same time, the lower swing arm is connected with the E-shaped support, and the lower swing arm is rotationally connected with the auxiliary frame through the front camshaft and the rear camshaft. According to the technical scheme, the entity rotating shafts are adopted, sothat a steering mechanism is independent from an independent suspension mechanism; the length of the axis of the knuckle is unchanged, and the angle is basically unchanged; mutual interference of theindependent suspension mechanism and the steering mechanism is avoided during movement, and the performance of the independent suspension and the steering mechanism is improved; and steering ease, returnability and safety of wheels are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, in particular to a steering pair placed on a double-wishbone independent suspension and an automobile thereof. Background technique [0002] Automobile suspension is an important part to ensure ride comfort. At the same time, as a force transmission part connecting the body (or frame) and axle (or wheel), the automobile suspension is also an important part to ensure the safety of the car. [0003] Independent suspension is to install the left and right wheels on one axle of the car separately under the body (or frame). The axle adopts a disconnected type, and the middle section is fixed on the body (or frame). The wheels do not affect each other when they are impacted, and because the suspension is light in weight, strong in buffering and shock absorption, the ride comfort is good. All indicators are better than the non-independent suspension, but the structure of the indep...
