Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stabilizer bar mounting unit for a vehicle suspension,

An exemplary embodiment of the present invention relates to a vehicle suspension, and more particularly, to a stabilizer bar mounting unit of a vehicle suspension for mounting a stabilizer bar to a subframe.

Generally, a suspension of a vehicle is a device that connects an axle and a vehicle body to prevent damage to the vehicle body and cargo, thereby improving ride comfort, by controlling vibration, shock, and external force, which the axle receives from the road surface during traveling, from being directly transmitted to the vehicle body.

Particularly, a McPherson type suspension mainly applied to a small passenger vehicle has a structure in which a strut bar 1 is installed by connecting an upper side of a knuckle 3 and a vehicle body (not shown) as shown in Fig. 1, A spring (5) is provided on the bar (1).

The subframe 110 is formed by welding an upper plate 7 and a lower plate 9 to each other. The subframe 110 is formed as an H-shape, for example, (Not shown), a stabilizer bar 111, and the like, and a lower arm 12 is provided at the front and rear ends of the stabilizer gear box (not shown) on both sides thereof to be connected to a lower side of the knuckle arm 3.

The subframe 110 is connected to the transmission via a mounting unit (not shown) for attenuating the vibration, noise and impact force of the transmission (not shown).

The stabilizer bar 111 is a part for controlling the tilting of the vehicle body when the vehicle is steered. The stabilizer bar 111 is disposed in front of a steering gear box (not shown) between the right and left wheels, To the front side.

In this case, the stabilizer bar 111 is for controlling the rolling motion of the vehicle body when traveling on a turning or rough road surface, and does not act when the left and right wheels simultaneously move up and down. However, when the left and right wheels move up and down differently, And the rolling motion of the vehicle body is suppressed by the restoring force due to the torsion, thereby securing the stability of the vehicle.

The conventional bush unit 200 for mounting the stabilizer bar 111 on the sub frame 110 includes a mount bush 111 to which the stabilizer bar 111 is fitted and which is supported on both sides of the front side of the sub frame 110 140 and a bush bracket 160 which surrounds the periphery of the mount bush 140 and is fastened to the subframe 110.

Therefore, in the prior art, the mount bushing 140 is mounted on the mounting surface of the subframe 110 while the stabilizer bar 111 is inserted into the mount bushing 140, and the mount bushing 140 The mounting of the stabilizer bar 111 to the subframe 110 is completed while the both side portions of the bush bracket 160 are fastened to the subframe 110 using the mount bolts MB .

However, in the prior art, when the vehicle collides, the transmission collides with the stabilizer bar 111 while striking the front portion of the subframe 110. When the collision load of the transmission is directly transmitted to the stabilizer bar 111, It is vulnerable to the absorption of the collision energy.

An exemplary embodiment of the present invention has been made to solve the above problems and it is an object of the present invention to provide a vehicle suspension stabilizer capable of absorbing a collision load of a transmission due to a collision between a transmission and a stabilizer bar through a stabilizer bar, Provides a bar mounting unit.

The stabilizer bar mounting unit comprises: i) And a bush bracket that supports the respective mount bushes and is coupled to the subframe, wherein the mount bushes are mounted on the stabilizer And a separation block for allowing the bar to be pushed from the coupling hole to the rear side.

In the stabilizer bar mounting unit of the vehicle suspension, the mount bushes include a pair of main blocks disposed on both sides of the separation block and sandwiched between the separation blocks and the separation block through the bush bracket .

The stabilizer bar mounting unit of the vehicle suspension is characterized in that the bush bracket includes a first bracket that surrounds one of the main blocks and is coupled to the sub frame, a second bracket that surrounds the other main block, Bracket.

In the stabilizer bar mounting unit of the vehicle suspension, the separation block may be disposed so as to be detachable between the main blocks to form the engagement hole, and to protrude outside the surface of the main block.

In the stabilizer bar mounting unit of the vehicle suspension, the first and second brackets may surround the main block and support the protruding portions of the separation block.

In the stabilizer bar mounting unit of the vehicle suspension, mount brackets may be provided on both sides of the sub frame.

In the stabilizer bar mounting unit of the vehicle suspension, the first and second brackets may be coupled to the respective mount brackets through mount bolts.

According to the stabilizer bar mounting unit of the vehicle suspension according to the exemplary embodiment of the present invention as described above, since the separation bush is configured in the mount bush for enabling the rearward pivoting of the stabilizer bar in the event of a vehicle collision, The stabilizer bar is pushed rearward by the collision load, so that the collision load can be absorbed and dispersed more effectively, which can further improve the collision performance of the vehicle.
