Description

Torque rod assembly of vehicle suspension

The present invention relates to a torque rod assembly of a vehicle suspension, and more particularly to a torque rod assembly of a vehicle suspension to prevent the bush from falling off the torque rod.

Generally, in the suspension of a vehicle, a bush is inserted into both ends of a torque rod supporting the axle, and the bush is fixed to the vehicle body, so that the impact or vibration transmitted from the road surface while driving is applied to the torque rod. By preventing direct transmission to the vehicle body, and through the bush to mitigate the impact.

1 is an exploded perspective view partially illustrating a torque rod assembly of a conventional vehicle suspension device, FIG. 2 is a partially cut away perspective view of the torque rod assembly of FIG. 1, and FIG. 3 is a torque rod assembly of FIG. 1. It is an internal cross section shown.

As shown, the conventional torque rod assembly of the vehicle suspension unit presses the bush 20 into the end housing 11 integrally provided at both ends of the torque rod 10, the groove 11a of the end housing 11 The snap ring 30 is fixed to the bush 20 as a structure to hold the expansion force of the bush 20 by inserting the snap ring 30 in the) and to prevent the bush 20 from being separated from the end housing 11. It is configured to.

The snap ring 30 is made of a material having elasticity, and has an open loop shape having an open portion 31 open at one side thereof, and the open portion 31 when press-fitted into the end housing 11. Is tightened to be pinched so as to fit in the groove 11a of the end housing 11.

Since the conventional torque rod assembly relies only on the snap ring 30 to prevent the detachment of the bush 20, the snap ring 30 may not be properly formed when the strength or assembly of the snap ring 30 is not properly performed. A problem of detachment occurs, which causes the bush 20 to be detached from the end housing 11, resulting in loss of function of the torque rod 10.

In addition, the snap ring 30 may be separated from the end housing 11 of the torque rod 10 due to the expansion force of the bush 20 concentrated in the opening 31.

The present invention has been invented to solve the above problems, a vehicle that can prevent the detachment of the bush and uniformly inhibit the expansion force of the bush by configuring a cap that is coupled to the end housing of the torque rod by screwing method The object is to provide a torque rod assembly of a suspension.

The present invention to achieve the above object is a torque rod which is provided with end housings at both ends; A bush press-fitted into the end housing; And a cap coupled to an inner side of the end housing at an upper portion of the bush to fix the bush.

Preferably, the cap is characterized in that formed in a ring shape.

Also preferably, a plurality of assembly grooves are formed in the cap to facilitate detachment of the cap to the end housing.

More preferably, the housing spiral portion is formed on the inner circumferential surface of the end housing, and the cap spiral portion corresponding to the housing spiral portion is formed on the outer circumferential surface of the cap to be engaged with each other.

More preferably, a support end for supporting the bottom surface of the cap is formed in the lower portion of the housing spiral of the end housing.

The present invention prevents the detachment of the bush by mounting the cap detachably fixed to the end housing of the torque rod, and the expansion force of the bush is concentrated on a specific portion of the cap by catching the expansion force of the bush in the entire portion of the ring-shaped cap To prevent the cap from leaving the end housing.

In addition, the present invention facilitates the assembly and disassembly of the torque rod by providing an assembly groove at the top of the cap, thereby reducing the process time for assembling and releasing the torque rod assembly.

There may be a plurality of embodiments of the present invention, and overlapping descriptions of the same parts as in the prior art may be omitted.

The present invention relates to a torque rod assembly of a vehicle suspension device, to configure the bush fixing means excellent in the coupling force to the end housing of the torque rod to prevent the fall of the bush.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 is an exploded perspective view showing a part of the torque rod assembly of the vehicle suspension according to the present invention, FIG. 5 is a combined perspective view showing a part of the torque rod assembly in FIG. 4, and FIG. 6 is a part of the torque rod assembly in FIG. 5. FIG. 7 is a cutaway perspective view of the cutting rod, and FIG. 7 is an internal cross-sectional view of the torque rod assembly of FIG. 5.

The torque rod assembly according to the present invention is coupled to the torque rod 100 having end housings 110 at both ends, the bush 120 press-fitted to the end housing 110, and the end housing 110. Cap 130 is made of a bush fixing means for preventing the separation of the 120.

As shown in FIG. 1, the present invention forms a housing spiral 111 on the inner circumferential surface of the end housing 110 in order to increase the coupling force between the torque rod 100 and the cap 130. The cap helical portion 131 corresponding to the housing spiral portion 111 is formed on the outer circumferential surface of the 130, so that the cap 130 and the end housing 110 are engaged with each other to be coupled in a screwing manner.

In this case, in order to prevent the cap 130 from being detached from the bush 120, when the cap 130 is coupled to the end housing 110, the bush is mounted to the end housing 110 of the torque rod 100. After pressing 120, the cap 130 is positioned on the bush 120.

To this end, the housing spiral part 111 is provided at an inner upper end of the end housing 110, and a support end 113 for supporting the bottom surface of the cap 130 is formed under the housing spiral part 111. do.

Accordingly, the housing spiral portion 111 is provided with a spiral formed to a predetermined position on the inner circumferential surface of the end housing 110.

In the present invention, the cap 130 is made of a closed loop shape of the ring shape to block the expansion force of the bush 120 in the entire circumferential direction in the same manner, and thus the bush (130) in a specific portion of the cap 130 Concentration of the expansion force of 120 can be prevented.

Accordingly, the coupling of the cap 130 to the torque rod 100 or the engine housing 110 is increased, thereby preventing the cap 130 from being separated from the engine housing 110 and removing the bush 120. Will be prevented.

On the other hand, the bush 120 is filled with a fluid that provides a predetermined pressure by increasing or decreasing the volume by the magnetic force therein, the torque rod assembly according to the invention is the end housing (B) by the expansion force of the bush (120) Unlocking (uncoupling) of cap 130 relative to 110 may have a self-locking function.

In addition, in the present invention, it is possible to apply an instant adhesive such as loctite to the cap helix 131 in order to enhance the loosening of the screw coupling between the cap 130 and the end housing 110.

In addition, by forming an assembly groove 133 that can be inserted and mounted to the tool on the upper portion of the cap 130, the user by using the assembly groove 133 to facilitate the removal of the cap 130 in the present invention The process time for assembling and disassembling the torque rod assembly can be shortened.

In the embodiment of the present invention, the assembling groove 133 is formed in plural, in order to facilitate the use of the tool is composed of two or four places is preferably arranged to face each other.

In this way, the work can be proceeded smoothly during manufacture of the torque rod assembly through the detachment of the cap 130 using the tool.

As described above, the present invention prevents the cap 130 from being separated by fixing the cap 130 that prevents the detachment of the bush 120 to the end housing 110, thereby preventing the departure of the bush 120. The function of the rod 120 can be maintained.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to these embodiments, and has been claimed by those of ordinary skill in the art to which the invention pertains. It includes all the various forms of embodiments that can be implemented without departing from the spirit.
