Abstract

The invention is a damping support device for a suspension mechanism, which comprises two dampers and two symmetrically arranged support groups. Each damper includes a sleeve and a moving rod. The moving rod can move with the sleeve relative to the sleeve. The cylinders are combined. Each support group is composed of a first support frame and a second support frame that are pivotally connected to each other. The top end of the first support frame is pivotally connected to the moving rod of the corresponding damper. The bottom end is pivotally connected to the side wall of the outer ring of the sleeve of the corresponding damper; since the sleeve and the moving rod of the damper are both pivotally connected to the support group, the support group can resist the radial bearing between the sleeve and the moving rod. The force keeps the sleeve and the moving rod in a specific axial relative relationship, so it can ensure that the damper moves normally and indeed exerts its preset effect, and can further extend the life of the damper.

Description

Damping support device of suspension mechanism

The invention relates to a vehicle supporting device, in particular to a damping supporting device of a suspension mechanism.

According to the general locomotive, the front and rear wheels are arranged in two lines on the same straight line, and the front wheels are arranged in a single wheel. The suspension mechanism of a general locomotive is mainly combined with the front wheel through two dampers, two of which are Capable of absorbing vibrations to maintain the handling and comfort of the locomotive on bumpy roads. However, for three- or four-wheeled locomotives with two side-by-side front wheels, the suspension mechanism and steering mechanism are both It is located above the two side-by-side front wheels, and its suspension mechanism is combined with the two front wheels through two dampers. The two dampers need to bear most of the weight of the suspension mechanism and the steering mechanism above it. Make sure that it is functioning properly.

However, the current damper's sleeve and the moving rod are axially actuated to absorb vibrations, but there is no mutual positioning restriction between the sleeve and the moving rod. Therefore, when the sleeve and the moving rod act axially, At the same time, radial rotation still occurs between the sleeve and the moving rod, especially when driving on poor roads, the reaction force transmitted from the wheel will cause the sleeve and the moving rod to bear both axial and radial The force of the damper will cause the load of the damper to exceed the preset range, which will not only keep the damper in a normal state, but also affect the life of the damper. Therefore, the existing dampers with side wheels installed side by side need to be improved. .

In order to solve the problem that the damper load of the existing suspension mechanism easily exceeds the preset range, and the lack and deficiency of the normal operation of the damper cannot be ensured, the main object of the present invention is to provide a damping support device for the suspension mechanism. Both the sleeve and the moving rod are pivotally connected to the support group.
