Anti-roll bar holder and shock absorber using the anti-roll bar holder

The present invention relates to a technical field of a vehicle shock absorber, in particular, an anti-roll bar holder that does not damage the structure of the shock absorber due to positioning, and a shock absorber using the anti-roll bar holder.

According to the configuration of the conventional automobile shock absorber 9, please refer to the figures 5 and 6, which are usually installed between the chassis of the vehicle body (not shown) and the axle (not shown), and the shock absorber 9 has a a screw 91, a telescopic rod 92 axially extending through the screw 91 and displaceable relative to the screw 91, and an upper limit seat 93 disposed on the upper portion of the telescopic rod 92 and connected to the chassis of the vehicle body, The adjusting ring sleeve 94 of the lower part of the screw 91 is disposed on the outer side of the telescopic rod 92 and the screw 91, and is elastically connected to the elastic element 95 between the upper limit seat 93 and the adjusting ring sleeve 94, and is screwed to the screw 91, and is located at the adjustment Below the collar 94, a base 96 for connecting to the axle, and a screw silled to the screw 91, and located between the adjustment collar 94 and the base 96, can be connected to an anti-roll bar 98 (commonly known as a tie rod) Tilting rod mount 97.

In order to adapt to different vehicle types and driving conditions, the adjusting ring sleeve 94, the base 96 and the anti-roll bar fixing seat 97 are all designed to be adjustable relative to the screw 91. The position of the nut structure is to facilitate the adjustment of the elasticity of the elastic member 95, the distance between the chassis of the vehicle body and the wheel, and the position and balance of the opposite ends of the anti-roll bar 98.

The anti-roll bar fixing base 97 has a nut 971 which is screwed on the screw 91 and an ear portion 972 which extends outward from the nut 971. One end of the anti-roll bar 98 is fixed at the ear portion 972, and is prevented by The tilt rod holder 97 can adjust the anti-roll bar 98 in the axially up and down positions of the screw 91 with respect to the screw 91. A nut 971 is disposed on one side of the nut 971 in a radial direction with a plurality of through-nuts 971 and a locking bolt 974 extending through the slot 973. The internal thread surface 975 of the nut 971 is matched with the thread of the screw 91. The ear portion 972 is disposed on the outer annular surface of the nut 971 with respect to the dissection groove 973.

Although the position of the anti-roll bar fixing seat 97 can be easily adjusted by the screwing of the internal thread surface 975 along the screw 91, and the locking bolts 974 are locked to reduce the spacing of the dissection grooves 973, the nut 971 can be clamped. Tightly fixed to the screw 91 to achieve the positioning effect; however, if the force is too large, the screw 91 may be squeezed (the screw is a hollow rod), causing the screw 91 to deform, eventually affecting the telescopic rod 92 in the screw 91. The fluency of the next activity reduces the suspension effect of the shock absorber 9.

In addition, as shown in FIG. 7 , another embodiment of the conventional anti-roll bar holder 80 has a nut 801 which is screwed on the screw 91 and an ear 802 extending outward from the nut 801 , and a nut The 801 has a ring wall 803, a female thread surface 804 formed on the inner side of the ring wall 803, a positioning hole 805 extending through the ring wall 803, and a positioning bolt 806 lockable into the positioning hole 805.

In use, the anti-roll bar holder 80 can be rotated by the internal thread surface 804 to the upper and lower preset positions of the screw 91. Then, the positioning bolt 806 is screwed to the positioning hole 805 and abuts against the surface of the screw 91. Therefore, the anti-roll bar holder 80 can be restricted from rotating relative to the screw 91 to achieve the positioning effect. However, since the top of the positioning bolt 806 abuts, the thread on the surface of the screw 91 is broken, and the anti-roll bar is fixed next time. When the seat is 80, the thread on the screw 91 is broken and deformed, and the anti-roll bar holder 80 is less likely to be displaced in the axial direction of the screw 91.

In order to solve the above-mentioned lack of the conventional structure, some manufacturers have proposed to solve the previous case, such as China Patent Publication No. I324663 "A locknut, anti-rolling anti-roll bar anti-roll bar mount, and anti-roll bar The shock absorber of the anti-roll bar holder is disclosed by the summary field. "The lock nut includes a main body unit and a positioning bolt screwed to the main body unit. The main unit includes a defined one. a perforated peripheral wall and a strip-shaped slit extending through the peripheral wall, the peripheral wall having a spaced-apart internal thread surface, an outer peripheral surface, an upper and lower end surface connected to the internal thread surface and the outer peripheral surface, the strip opening The slot is defined by an upper slot surface and a lower slot surface, the peripheral wall further having an upper screw hole extending from the upper end surface to the upper slot surface, and an alignment of the upper screw hole and extending from the lower slot surface to a lower screw hole penetrating the lower end surface. The positioning bolt is screwed to the upper and lower screw holes to locally deform the internal thread surface to achieve a stable locking effect.

Although the previous case (I324663) can solve the lack of deformation of the screw 91 caused by the conventional structure, the structure still has the following defects: the conventional case has a slot in the side of the main unit, so that The main unit is complicated to process and troublesome; because the opening of the strip-shaped groove will cause the internal thread surface to be continuous, how to ensure the smoothness of the internal thread surface is screwed, and the yield of the product is obviously tested. Moreover, the opening of the strip-shaped groove will inevitably form a burr on the inner thread surface. If it is not cleaned, it will cause obstacles and difficulties in screwing. If the cleaning is arranged, an additional process must be added.

In addition, the conventional internal thread surface can only be partially deformed, and cannot be annular and the overall threaded thread is tightly pressed, so that the positioning effect can only be localized, posing a potential positioning risk.

In view of the above problems and deficiencies of the prior art, one of the aims of the present invention is to provide an anti-roll bar holder and a shock absorber using the anti-roll bar holder, in addition to facilitating the user to adjust the anti-roll bar holder. It can be properly fixed to the preset position of the shock absorber, and avoid the advancement of the structure and thread of the shock absorber due to the positioning of the anti-roll bar fixing seat.

The anti-roll bar fixing base 2 is screwed on the screw 11 and located between the adjusting ring sleeve 14 and the base 16 to provide an anti-roll bar 98 (commonly known as a tie rod) connection; the anti-roll bar holder 2 includes a screw sleeve on the screw An upper positioning ring 21, a lower positioning ring 22, a connecting lug 23 selectively protruding from one of the upper and lower positioning rings 21, 22, and a plurality of legs for forming the upper and lower positioning rings 21, 22 The positioning bolt 24 is axially supported or clamped in the opposite direction.

The upper positioning ring 21 includes an upper shaft hole 211 and a plurality of upper locking holes 212, and an upper threaded portion 213 is formed on the inner surface of the upper shaft hole 211. In implementation, the upper positioning ring 21 is threaded onto the screw 11 by the upper threaded portion 213. The locking holes 212 are symmetrically arranged, and can be selectively used for screw holes, class holes, or omitted. The thread of the upper threaded portion 213 may be a single thread or a multi-thread thread. In addition, the outer ring surface of the upper positioning ring 21 can selectively adopt a circular toroid or a polygonal toroid (for example, a quadrangular torus, a pentagonal torus, a hexagonal torus, and an octagonal torus).

The lower positioning ring 22 includes a lower shaft hole 221 and a plurality of lower locking holes 222 formed in the axial direction and in parallel through the lower positioning ring 22, and the inner surface of the lower shaft hole 221 forms a lower thread portion 223.
