FRONT LIFTING SYSTEM FOR VEHICLE

Abstract

A front lifting system for vehicle comprises a threaded pipe, an annular hydraulic unit, and a fixing base. When the threaded pipe covers a shock absorber, a spring covers a damper of the shock absorber and two ends of the spring are respectively abutted against the annular hydraulic unit and the damper. At this time, the annular hydraulic unit does not act. When the annular hydraulic unit acts, it pushes the spring upwardly and further the spring pushes the damper upwardly so that the front of the vehicle may be lifted up to prevent the front of the vehicle with lower chassis from damage while going uphill or downhill.

Claims

1. A front lifting system for vehicle, comprising: a threaded pipe adapted to cover an existed shock absorber which has at least one shoulder portion, the threaded pipe having an outer threading portion formed at an outer surface thereof; at least one step portion formed at an inner surface of the threaded pipe, the at least one step portion is adapted to be abutted against the at least one shoulder portion of the existed shock absorber; a ring base having an inner threading portion, the inner threading portion is screwed with the outer threading portion of the threaded pipe, the ring base being moved upward and downwardly by being threaded relative to the threaded pipe; an annular hydraulic unit mounted to the threaded pipe and being abutted against an upper surface of the ring base; a fixing base adapted to be connected with a stabilizer link, the fixing base screwed with the threaded pipe and located below the ring base.

2. (canceled)

3. (canceled)

4. (canceled)

5. The front lifting system for vehicle as claimed in claim 1, wherein the ring base is separated from the fixing base with a predetermined distance, and the predetermined distance is adjusted by screwing the ring base relative to the threaded pipe.

6. The front lifting system for vehicle as claimed in claim 1, wherein the threaded pipe is made of an aluminum material.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023] Referring now to the drawings where like characteristics and features among the various figures are denoted by like reference characters.

[0024] Please refer to FIGS. 1 to 8, a front lifting system 100 for vehicle may comprise a threaded pipe 1 which is made of an aluminum material, but not limited thereof.

[0025] The threaded pipe 1 may cover a shock absorber 200 which is suitable for the Electronic Damping System.

[0026] The shock absorber 200 has at least one shoulder portion 210. At least one step portion 11 is formed at an inner surface of the threaded pipe 1. The at least one step portion 11 is abutted against the at least one shoulder portion 210 of the shock absorber 200.

[0027] Please refer to FIG. 3, it shows a first embodiment of the front lifting system 100 for vehicle. There are two step portions 11 and two shoulder portions 210 whose quantity is corresponding to the quantity of the step portions 11.

[0028] Please refer to FIG. 7, it shows a second embodiment of the front lifting system 100 for vehicle. There is single one step portion 11 and single one shoulder portion 210 whose quantity is corresponding to the quantity of the step portion 11.

[0029] The front lifting system 100 for vehicle may further comprise a ring base 2. The ring base 2 has an inner threading portion 21. The threaded pipe 1 has an outer threading portion 12 formed at an outer surface thereof. The inner threading portion 21 is screwed with the outer threading portion 12 for adjusting upwardly and downwardly.

[0030] The front lifting system 100 for vehicle may further comprise an annular hydraulic unit 3. The annular hydraulic unit 3 covers the threaded pipe 1 and is abutted against an upper surface of the ring base 3. That is, the annular hydraulic unit 3 is located above the ring base 2.

[0031] The front lifting system 100 for vehicle may further comprise a fixing base 4 for connecting a stabilizer link (not shown). The fixing base 4 is screwed with the threaded pipe 1 and located below the ring base 2. The fixing base 4 may be moved upwardly and downwardly relative to the threaded pipe 1 by screwing so as to adapt the lengths of stabilizer links (not shown) of different kinds of vehicles.

[0032] In addition, the ring base 2 is separated from the fixing base 4 with a predetermined distance D (shown as in FIG. 3). The predetermined distance D may be adjusted by screwing the ring base 2 relative to the threaded pipe 1.

[0033] Please refer to FIGS. 5 and 6, when the threaded pipe 1 covers the shock absorber 200, a spring 300 covers a damper 220 of the shock absorber 200 and two ends of the spring 300 are respectively abutted against the upper surface of the annular hydraulic unit 3 and the end of the damper 200 which is distant from the annular hydraulic unit 3. At this time, the annular hydraulic unit 3 does not act. Please refer to FIG. 7, when the annular hydraulic unit 3 acts, the annular hydraulic unit 3 pushes the spring 300 upwardly and further the spring 300 pushes the damper 220 upwardly so that the front of the vehicle (not shown) may be lifted up to prevent the front of the vehicle with lower chassis from damage while going uphill or downhill.

[0034] The foregoing descriptions are merely the exemplified embodiments of the present invention, where the scope of the claim of the present invention is not intended to be limited by the embodiments. Any equivalent embodiments or modifications without departing from the spirit and scope of the present invention are therefore intended to be embraced.

[0035] The disclosed structure of the invention has not appeared in the prior art and features efficacy better than the prior structure which is construed to be a novel and creative invention, thereby filing the present application herein subject to the patent law.
