CN202768722U - Dual-spring rear shock absorber of knight-type motorcycle - Google Patents

Abstract

The utility model discloses a dual-spring rear shock absorber of a knight-type motorcycle, which comprises an upper guide tube component, a lower guide tube component, an outer shock absorbing spring, an inner shock absorbing spring and a damper, wherein the damper is connected between the upper guide tube component and the lower guide tube component; a shock absorbing pad is arranged in the damper; a regulator is arranged outside the damper; a dust-proof cover is mounted outside the lower end of an upper guide tube, a spring seat is mounted at the lower end of a lower contact; the damper is sleeved with the outer shock absorbing spring; one end of the outer shock absorbing spring is mounted on the spring seat; the inner shock absorbing spring is arranged between the damper and the outer shock absorbing spring; and one end of the inner shock absorbing spring is mounted on the spring seat. Compared with the original single-spring rear shock absorber, the dual-spring rear shock absorber is stronger in bearing capacity, and more stable and softer in shock absorption performance, and particularly meets requirements of people in rural areas and mountainous areas on heavier goods loading.

Description

A kind of riding motorcycle double-spring rear shock absorber

Technical field

The utility model relates to a kind of component of motorcycle, more specifically to the motorcycle double-spring rear shock absorber that uses on a kind of motorcycle.

Background technique

At present, the rear shock absorber that uses on the riding motorcycle is single spring rear shock absorber, and single spring rear shock absorber damping performance is relatively poor, not too adapts to when motorcycle loads than parcel in the bad place walking of the road conditions such as rural area and mountain area.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of riding motorcycle double-spring rear shock absorber to be provided, and it is stronger than former single spring rear shock absorber bearing capacity, and damping performance more steadily and soft.

The purpose of this utility model is achieved by the following technical programs: a kind of riding motorcycle double-spring rear shock absorber, comprise the upper conduit assembly, the downcomer assembly, damper and outer damping spring, connection damper between upper conduit assembly and the downcomer assembly, the upper conduit assembly is by upper connection, upper conduit and upper sebific duct form, the downcomer assembly is by lower contact, downcomer and lower sebific duct form, damper inside is provided with beam, the damper outer installment has regulator, dust-proof cover is equipped with in outside, upper conduit lower end, the lower contact lower end is equipped with spring seat, outer damping spring is enclosed within the damper outside, one end of outer damping spring mounts elastically, it is characterized in that between damper and outer damping spring, being provided with the internal damping spring, one end of internal damping spring mounts elastically, upper connection and lower contact adopt cast aluminium to make, can make like this upper connection and lower contact corrosion-resistant, and it is not yielding, dust-proof cover, regulator and damper surface coverage have the decorative chromium plating layer, can make so the antirust and beautiful shape of riding motorcycle double-spring rear shock absorber.The internal damping spring is sign

Wire spring, outer damping spring for the sign $\frac{6.5-11-\mathrm{GB}342-82}{65\mathrm{Mn}-C-\mathrm{GB}4357-84}$ Wire spring.

Can find out that from above technological scheme the present technique content is to convert at former single spring rear shock absorber, change inside and outside two damping springs into by the wall scroll damping spring, inside and outside dual spring combination, double-spring rear shock absorber is installed in the effective travel that does not change vibration damper on the riding motorcycle, and shock resistance is good, bearing capacity strong, damping performance is more steadily soft, adapts to especially the rural area, the mountain area masses load the demand than parcel.
