Abstract

The utility model discloses a downward and upward counteractive bar assembly with a rubber joint in front of a rear suspension, comprising a bar body, a bar head, a joint and an elastic piece. The bar head is fixed on the end of the bar body, on which is columniform cavum, where the joint is arranged inside by the elastic piece. Two ends with a pin hole of the joint extend outwards. The middle of the joint presents an annular heave shape. A bracing ring is arranged respectively on both ends of the elastic piece. The inside wall of the cavum of an end of the bar head is arranged with a protruding edge, which is clamped closely with the corresponding elastic piece, while the inside wall of the cavum of the other end is arranged with an annular clamping slot for installation of the clip spring, which will cling to the bracing ring at the corresponding end to fix the joint and the elastic piece inside the cavum. Compared with the conventional joint, the model has the advantages of simple structure, being easy for assembly, disassembly and replacement, stable and reliable performance, heavy load and long period of usage, etc, substantially reducing the loss of vehicle owner due to frequent replacement of the joint assembly.

Description

Reach down before a kind of rear suspension and go up back reaction rod band elastomer connector assembly

Technical field

Preceding the reaching down that the utility model relates in a kind of rear overhang rack balance sysmte gone up reaction rod joint assembly.

Background technique

The rear-suspension system of automobile mainly comprises trunnion shaft, balance shaft housing, spring, preceding reaching down gone up back reaction rod, support etc., reaching the two ends of going up back reaction rod wherein down is connected with vehicle frame with track bar bracket respectively, actuating rod is except bearing longitudinal force, also bear the radially torque of bearing pin and along vertical torque of actuating rod assembly axis, therefore the quality of actuating rod connector assembly seems particularly important to whole rear-suspension system, but existing various actuating rod connector assembly is because complex structure, the consumption of metal and rubber is all very big in working process, and rigidity is low, in use elastomer is easy to crack, come off, wearing and tearing, entrucking is short working life.

The model utility content

At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of long service life, rear suspension stable and reliable for performance, that load capacity is big is down preceding and go up back reaction rod band elastomer connector assembly.

For achieving the above object, the technical solution adopted in the utility model is: reach down before a kind of rear suspension and go up back reaction rod band elastomer connector assembly, comprise shaft, the bar head, joint and elastic component, the bar head is fixed on the shaft end, has a cylindrical cavity on it, joint is installed in this cavity by elastic component, its two ends that have pin-and-hole are protruding, described joint middle part is convex ringwise, the elastic component two ends are respectively arranged with support ring, the inwall of described bar head cavity one end is provided with the convex edge, this convex edge and corresponding elastic component support ring chucking, the inwall of the cavity the other end is provided with the annular slot that is used to install jump ring, and the support ring of jump ring and respective end compresses joint and elastic component are fixed in the cavity of bar head.

Described joint middle part is spherical in shape.

The outer edge place at described elastic component two ends offers the annular recess that matches with support ring respectively.

Described elastic component is made by rubber material, and sulfuration is at the middle part of joint.

Described shaft is a hollow-core construction, and disputer one side is provided with a protuberance, and this protuberance stretches into shaft cavity certain distance, and both weld fixing or heating presses groove to fix through mould.

The elastic component sulfuration is at the joint middle part that is convex in the utility model, both are bonding firmly, and be fixed in the bar head by jump ring and support ring, elastic component cooperates tightly with bar head and joint, compare with the traditional jointing assembly have replacing simple in structure, easy to assemble, stable and reliable for performance, advantages such as load capacity big, long service life, reduced the loss that brings to the car owner because of frequent replacing connector assembly.

Description of drawings

Fig. 1 is an overall schematic of the present utility model;

Fig. 2 is the utility model first embodiment's a cross-sectional schematic;

Fig. 3 is the utility model second embodiment's a cross-sectional schematic.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 1, first embodiment shown in Figure 2, reach down before the utility model and go up back reaction rod band elastomer connector assembly mainly by shaft 1, bar head 2, joint 3 and elastic component 4 are formed, it is more flat cylindric that bar head 2 is, one installation shaft 5 is arranged on its sidewall, shaft 1 is a hollow-core construction, installation shaft 5 stretches into certain distance in the shaft 1, the jointing welding is fixing, one cylindrical entire body cavity is arranged on the disputer 2, the middle part of joint 3 is convex ringwise, sulfuration has the elastic component of being made by rubber material 4 on it, it is cylindric that the outer surface of elastic component 4 also is, and matches with cavity internal surface on the bar head 2, and the inwall of bar head 2 upper plenums one end is provided with the convex edge, this convex edge and corresponding support ring 6 chuckings, the inwall of the cavity the other end is provided with the annular slot that is used to install jump ring 7, and the support ring 8 of jump ring 7 and respective end compresses joint 3 and elastic component 4 are fixed in the cavity of bar head 2, and it is protruding that joint 3 has the two ends of pin-and-hole, support ring 6 is identical with support ring 8 structures, is bending-like on the longitudinal section

Shape, it is inboard to compress mutually with elastomer 4, and its outside is fixing with convex edge and jump ring 7 chuckings, offers the annular recess that matches with support ring at elastic component 4 with the place of compressing mutually of support ring, so that both full contacts, fix reliably.

The 3rd embodiment as shown in Figure 3, the middle part of joint 3 is spherical in shape, and the installation shaft 5 of bar head 2 stretches into certain distance in the shaft 1, and both heating are after mould presses groove to fix, and other structures are identical with first embodiment.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but on its shape or structure, do any variation; every have identical with a utility model or akin technological scheme, all drops within the application's the protection domain.
