Embodiment 1

[0018] Such as figure 2 As shown, the drum-type shock-absorbing suspension device in this embodiment includes an inner steel cylinder 2 and an outer steel cylinder 3 coaxially set and an elastic rubber 1 filled between the inner steel cylinder and the outer steel cylinder, such as figure 2 image 3 As shown, in the vertical direction, there is a half-moon-shaped axial gap 5 between the part of the inner surface of the outer steel cylinder 3 and the rubber 1, and the axial gap 5 runs through both ends of the entire suspension device and is vertically arranged The axial gap 5 is symmetrical about the axis of the outer steel cylinder 3, and the vertically arranged axial gap 5 makes there be more space for deformation in this direction, so that the stiffness in this direction is reduced and smaller than that of the left and right sides. For the stiffness in the transverse direction, by designing the size of the axial gap, the vertical and transverse stiffness of the shock absor...

Embodiment 2

[0020] Such as Figure 5 As shown, compared with Example 1, the difference lies in the setting position of the axial gap 5. In this embodiment, the axial gap is set in the elastic rubber 1, between the axial gap 5 and the outer steel cylinder 3 A layer of relatively thin rubber is adhered to the outer steel cylinder 3 to enhance the connection strength between the elastic rubber 1 and the outer steel cylinder 3 .

Abstract

The invention relates to a drum-type shock absorption suspension device. Aiming at the defect that the shock absorption performance of the traditional drum-type shock absorption suspension device is not adapted to the shock characteristic of a cab, the invention constructs the drum-type shock absorption suspension device comprising an inner steel cylinder and an outer steel cylinder which are sleeved coaxially, wherein rubber is filled between the inner steel cylinder and the outer steel cylinder; the inner surface of the outer steel cylinder has two opposite partial inner surfaces, and gaps exist between the partial inner surfaces and the rubber and axially pass through two ends of the outer steel cylinder. Due to the existence of the gaps, the vertical rigidity and the longitudinal rigidity of a shock absorber are different; and the sizes of the gaps are determined according to the shock characteristics of various different devices, and thus, the shock absorption property of the shock absorber can be consistent with that of the cab.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to a drum type shock absorbing suspension device. technical background [0002] The roller shock absorber is a kind of shock absorber with simple structure, such as figure 1 As shown, it usually consists of an outer steel cylinder 3, an inner steel cylinder 2 sleeved in the outer steel cylinder 3, and elastic rubber 1 filled between the outer steel cylinder 3 and the inner steel cylinder 2. This kind of shock absorber has a simple structure and is easy to install. , often used in the installation of construction machinery cabs, which play a shock-absorbing role in the cab and improve the comfort of the cab. However, since the rubber is filled between the inner steel cylinder and the outer steel cylinder of this drum type shock absorbing suspension, its vertical and lateral rigidity are the same, but the vertical and lateral vibrations of the cab are different, so the shock absorber The ...
