Summary of the invention
The purpose of this utility model is exactly to provide a kind of spring to be assemblied in the inside of cylindrical bar, and shock absorber is housed, good damping result, stability, the mechanical hydraulic-pressure type damper of motorcycle that fiduciary level is high.
The purpose of this utility model is achieved in that a kind of mechanical hydraulic-pressure type damper of motorcycle, comprise upper joint sleeve 1, lower joint sleeve 2, upper joint sleeve 1 is connected with high-voltage oil cylinder 3 by gland 4, lower joint sleeve 2 is connected with low pressure oil cylinder 5, gland 4 is installed on the buffer beam 6, low pressure oil cylinder 5 two ends are provided with oil cylinder loam cake 7 and oil cylinder lower cover 8, main spring 9 is housed in the low pressure oil cylinder 5, in the high-voltage oil cylinder 3 in the buffer beam 6 auxiliary spring 10 is housed, low pressure piston 11 is housed in the low pressure oil cylinder 6, be provided with retracing spring 12 between low pressure piston 11 and the oil cylinder loam cake 7, low pressure piston 11 is provided with oil through 13, be provided with high pressure piston 14 in the high-voltage oil cylinder 3, high pressure piston 14 is fixing by auxiliary spring 10.Be provided with seal ring 15 between buffer beam 6 and the gland 4.Between low pressure oil cylinder 5 and the oil cylinder loam cake 7 and oil cylinder lower cover 8 between be provided with seal ring 16,17.Be provided with y-shaped ring 18 between high pressure piston 14 and high-voltage oil cylinder 3 inwalls.
The utility model makes the shock absorber good looking appearance owing to adopted the structure of built-in spring; Adopt the principle of work of spring and the dual vibration damping of hydraulic pressure, good damping result, stability is high; The setting of a plurality of seal rings oil leakage phenomenon can not occur in the use, has improved fiduciary level, is convenient to maintenance; Guidance quality is strong in motion process, long service life.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The structure of this device is: a kind of mechanical hydraulic-pressure type damper of motorcycle, comprise upper joint sleeve 1, lower joint sleeve 2, upper joint sleeve 1 is connected with high-voltage oil cylinder 3 by gland 4, lower joint sleeve 2 is connected with low pressure oil cylinder 5, gland 4 is installed on the buffer beam 6, low pressure oil cylinder 5 two ends are provided with oil cylinder loam cake 7 and oil cylinder lower cover 8, main spring 9 is housed in the low pressure oil cylinder 5, in the high-voltage oil cylinder 3 in the buffer beam 6 auxiliary spring 10 is housed, low pressure piston 11 is housed in the low pressure oil cylinder 5, is provided with retracing spring 12 between low pressure piston 11 and the oil cylinder loam cake 7, low pressure piston 11 is provided with oil through 13, be provided with high pressure piston 14 in the high-voltage oil cylinder 3, high pressure piston 14 is fixing by auxiliary spring 10.Be provided with seal ring 15 between buffer beam 6 and the gland 4.Between low pressure oil cylinder 5 and the oil cylinder loam cake 7 and oil cylinder lower cover 8 between be provided with seal ring 16,17.Be provided with y-shaped ring 18 between high pressure piston 14 and high-voltage oil cylinder 3 inwalls.
When this device uses, by upper joint sleeve 1 and lower joint sleeve 2 shock absorber is installed on vehicle body and the wheel, under complete vehicle curb condition, the bounce of retracing spring 12 is lower than 9 main springs, low pressure piston 11 is in low pressure oil cylinder 5 lower ends, if retracing spring 12 is slightly stressed, main spring 9 is in slight strained condition, hydraulic oil in the low pressure oil cylinder 5 is near the lower surface of low pressure piston 11, and retracing spring 12 is in normal condition.
During vehicle stand under load cruising, upper joint sleeve 1 and lower joint sleeve 2 produce pressure, gland 4 and buffer beam 6 are moved, drive low pressure piston 11 compression main springs 9, hydraulic oil enters the upper space of low pressure piston 11, because during cruising, upper joint sleeve 1 and lower joint sleeve 2 stressed less and even, hydraulic oil only commutes the upper and lower surface of low pressure piston 11.
When vehicle runs into bigger vibration, load strengthens, the pressure that upper joint sleeve 1 and lower joint sleeve 2 produce strengthens, make the mobile increasing of gland 4 and buffer beam 6, driving low pressure piston 11 moves down, compression main spring 9, the hydraulic oil in the low pressure oil cylinder 5 enters the high-voltage oil cylinder 3 of buffer beam 6 by oil through 13, promotes high pressure piston 14 and moves down, cause auxiliary spring 10 stressed work, when low pressure piston 11 two ends stress balances, pressurized process finishes, and recovers just often, the pressure that upper joint sleeve 1 and lower joint sleeve 2 produce reduces, low pressure piston 11 moves up under the effect of the bounce of retracing spring 12, and the hydraulic oil in the high-voltage oil cylinder 3 is back in the low pressure oil cylinder 5, the top and bottom stress balance of high pressure piston 14 destroys, under the effect of the bounce of auxiliary spring 10, high pressure piston 14 is quickened to move down, and hydraulic oil flows into low pressure oil cylinder 5 rapidly, under the combined action of the bounce of hydraulic oil and spring, low pressure piston 11 rises, and drives buffer beam 6 and rises to normal operating condition, finishes the vibration damping process one time.
Be provided with seal ring 15 between buffer beam 6 and the gland 4, be provided with seal ring 16,17 between low pressure oil cylinder 5 and the oil cylinder loam cake 7 and between the oil cylinder lower cover 8, be provided with y-shaped ring 18 between high pressure piston 14 and high-voltage oil cylinder 3 inwalls and be that to play envelope close, prevent that hydraulic oil from rushing down the effect of leakage.
