Abstract

PURPOSE: To adjust the length of a torque rod provided with a first mounting end and a second mounting end and having a longitudinal shaft body by making the shaft body and both ends of polymerizable synthetic material. CONSTITUTION: At first, half rod shafts 62 and 65 are fixed to desired parts of a vehicle chassis separately. When fixing them, they are positioned such that both of the ends 63 and 64 of the half rods 62 and 65 are completely connected to each other. Since these ends 63 and 64 are connected to each other with play, the length of a torque rod is varied as occasion demands. A sleeve member 66 is located on the rod shaft 65 and when the rod shafts 62 and 65 are connected to each other, a passage C is formed between the ends 63 and 64, and when the member 66 is made to slide, it completely covers the ends 63 and 64. Since the member 66 scarcely has play to the rod shafts 62 and 65, both of the rod shafts 62 and 65 are aligned to each other at each center, and an opening 68 is aligned to the passage C. After that seal joint agent is poured from the opening 68 to integrate synthetic materials forming the rod shafts 62 and 65 and the member 66.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to torque rods, and more particularly to torque rods for use in certain vehicles made of polymerizable polymeric materials, and for use in drive train components of said vehicles. The present invention relates to an I-lecture rod that connects the vehicle chassis and the vehicle chassis and stabilizes the drive train by mitigating the strains that the vehicle receives from road and terrain conditions when the vehicle is accelerating, stopping, or operating. Such a torque rod is
It is fixedly attached to the differential housing and the vehicle chassis in the axial direction, parallel direction, or diagonal direction.

BACKGROUND OF THE INVENTION Torque rods for automotive vehicles, particularly vehicles with tandem axle suspension, are well known. Rods of this type in use today are substantially made of steel and have a steel shaft with a pair of straddle mounting ends, each with a lateral opening defining a socket. ing. The mounting end has a mounting flange with an opening for mounting at a specific location on the chassis and drive train side.

There are basically two types of straddle attachment ends. One has a central ball with a pair of outwardly extending mounting flanges that fit into respective sockets. An insulating lining material made of plastic or metal is interposed between the ball and the socket. Additionally, the ball and lining are secured within the socket by one or more rings positioned by presses, stakes or flanges in a snap-ring fashion. The advantage of this arrangement is that the ball is fully rotatable relative to the socket and there is a high angular contact between them.

A second type of straddle mounting end has a cylindrical bin body with two outwardly extending flanges mounted in respective sockets. A rubber insulating lining material is interposed between the bottle main body and the socket. During assembly, this rubber is deformed and fitted between the inner surface of the socket and the surface of the cylindrical bottle body. With this structure,
The angulation and rotation of the pin relative to the socket is regulated.

(Problems to be Solved by the Invention) However, the above conventional structure has the following problems. First, conventional torque rods are heavy, weighing approximately 20 bonds.

Second, they are difficult to manufacture, requiring almost complete casting or forging techniques and a high degree of expertise in assembly operations using heavy presses and the like.

Third, traditional torque rods are expensive to manufacture and replace because they are difficult to manufacture and the raw materials required are expensive.

Fourth, the insulating lining material interposed between the pole and the socket is prone to wear. And fifth, since the length of the conventional torque rod cannot be adjusted,
Incompatibility for different vehicle types.

(Means, actions and effects for solving the problem) Therefore,
The first object of the present invention is to make a material from a polymerizable material,
Another object of the present invention is to provide a torque rod whose length can be adjusted. When the rod is constructed as a single structure, flanges integrally formed with the rod shaft are provided at both ends of the rod. Moreover, the rod shaft is
Constructed as a hollow, solid, or multilayered structure with multiple concentric layers.

On the other hand, even when the rod shaft is configured as a two-piece structure, the shaft is divided into two halves, and each of the halves has ends that can be connected to each other with a clearance. Otherwise, it has the same structure and precepts as above.

A sleeve provided with an injection opening is slidably disposed on both connectable rod ends. After adjusting the two halves to each other to obtain the desired length (this adjustment may be performed after or before the attachment of the two halves to the vehicle body). (b), sliding the sleeve over the coupling connection and injecting seal bonding agent into the passageway in the coupling through the opening. Then, when this adhesive hardens,
Both halves are connected substantially integrally.

10 The torque rod having the above structure solves the problems of the prior art described above. That is, firstly, compared to conventional torque rods, torque rods made of composite materials have
Its weight is less than half. Second, the construction, which may include shaping, polishing, shaving, etc., is relatively simple.

Third, the resulting manufacturing and replacement costs are low. Fourthly, since no insulating lining material is used, there is no risk of this lining material being worn out. And the fifth
However, the structure using synthetic materials according to the present invention allows for easy adjustment of the length of the torque rod.
