Rhombus suspended frame for changing direction of vehicle

Abstract

The invention discloses a rhombic steering suspension for a vehicle, comprising a tire, a spoke on the tire, a rolling external ring, a rolling internal ring, a bearing, a steering mechanism, a support rod and suspension arms. The rolling external ring is fixed on the spoke and disposed on the rolling internal ring through the bearing. The steering mechanism comprises a king pin, a king pin bush, a steering hydraulic cylinder, a king pin copper bush and a king pin small bush, the king pin bush is fixed on the middle part of the support rod and sleeves the king pin through the king pin copper bush, the king pin is arranged in the rolling internal ring along the radial direction of the bearing, and the lower end of the king pin is supported on the bearing, the upper ends of the king pin, the king pin bush and the king pin copper bush are supported on the bearing through the king pin small bush. One end of the steering hydraulic cylinder connects with the rolling internal ring, and the other end is hinged to the end of the support rod, two suspension arms are respectively hinged to the two ends of the support rod. The suspension employs a design having a small height size and capable of lowering the vehicle instrument panel, can quickly dismantle the tire, and is favourable to improve the operation stability and running safety of the vehicle.

Description

technical field [0001] The invention relates to a vehicle suspension system and a steering system, in particular to a diamond vehicle steering suspension. Background technique [0002] In the vehicle chassis layout scheme, the steering system is closely related to the suspension, and there are mainly single-wheel steering and two-wheel steering. If the two steering wheels of the vehicle are symmetrically arranged left and right along the forward direction of the vehicle, the two-wheel steering scheme of the vehicle is generally adopted, such as ordinary cars and buses. The two front suspensions simultaneously undertake the steering function, and the front left suspension and the front right suspension pass Driven by the steering rod, the coordination of the steering angle of the left and right suspensions is achieved through the trapezoidal mechanism. The corresponding suspension driving forms include cross-arm suspension, trailing-arm suspension, MacPherson suspension and s...

AI Technical Summary

Problems solved by technology

If a single steering wheel is arranged in the center plane of symmetry in the forward direction of the vehicle, single-wheel steering is used, such as a vehicle with a three-wheel chassis and a four-wheel vehicle with a diamond chassis. At present, the steering suspension of this chassis layout mainly adopts motorcycle fork type. Suspension is not conducive to the interior space layout of the vehicle and the removal of tires. Vehicles with this type of suspension have a relatively large suspension height, so the dashboard will be designed higher

If a two-wheel steering suspension is used, this type of suspension is generally supported on one side, and the steering suspension of a diamond-shaped vehicle is arranged in the symmetrical plane of the vehicle, which will cause the suspension to support the vehicle asymmetrically, making the front wheels Leaning to one side affects the handling stability and driving safety of the vehicle
