Abstract
A motorcycle full suspension rear axle apparatus comprises a transmission semiaxis, an axle housing, a brake disc, a brake drum assembly, a stripped nut assembly, a semiaxis bolt, a bearing 1, a bearing 2, a hole type back-up ring and a sealing ring, wherein the peripheral of the transmission semiaxis is provided with the axle housing; the peripheral of one end of the axle housing is provided with the brake drum assembly; the joint of the brake drum assembly and the transmission semiaxis is provided with the sealing ring; the brake drum assembly and the transmission semiaxis are connected by the stripped nut assembly through the sealing ring; and the joint where the end face of the top end of the transmission semiaxis and the brake drum assembly are combined is provided with the semiaxis bolt. All gravity is effected to the brake drum and the axle housing assembly when a motor tricycle bears weight, therefore the gravity is transmitted to the semiaxis to drive the motor tricycle move, load to the load-carrying by the transmission semiaxis is avoided, operation efficiency is raised, and service life of the transmission semiaxis is greatly increased; the motorcycle full suspension rear axle apparatus also has a simple structure and obvious weight reduction effect, and is suitable for popularization and usage.
Description
Technical field
The utility model is related to bicycle for old people vehicle bridge field, and especially a kind of motorcycle suspends rear axle entirely.
Background technology
At present, motorcycle rear axle is tapered configuration, easy to operate due to simple in construction, and traveling is flexible, and convenient use, price is relatively low, deep to be loved by vast old client, gos out and rides instead of walk or lie fallow using very convenient.But, because structure design is simple, car back axle uses single-bearing, brake drum is after gravity is born, power is directly passed and replaced onto bearing, pass and replace onto jackshaft through bearing again, various stress suffered by the part of each transmission power are far longer than other positions of power train, easily cause the damage of bearing, when vehicle jolts in traveling, jackshaft bears most of load weight, in the presence of various angle change power, the transmission resistance and loss for making vehicle increase, making the efficiency of mechanical movement reduces, the concentricity accuracy of axle housing and jackshaft is not high, so as to cause jackshaft to be broken, cause flywheel accident.
Number of patent application discloses a kind of Integral motor-driven axle of electric vehicle for 201020669553.3, and brake drum is directly delivered on jackshaft after gravity is born, long-term to use the fracture for easily causing jackshaft.
In view of the foregoing, existing bicycle for old people rear axle structure needs to improve.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art; a kind of motorcycle is provided to suspend full rear axle; brake drum is after gravity is born; gravity is passed by duplex bearing and replaced onto axle housing; so as to protect jackshaft; extend the service life of jackshaft, it is to avoid the generation of flywheel accident.
The utility model to achieve these goals, is adopted the following technical scheme that：A kind of motorcycle suspends rear axle entirely, be by：Jackshaft, axle housing, brake disc, brake drum component, stripped nut component, half axle bolt, bearing one, bearing two, pass back-up ring, sealing ring is constituted；Jackshaft periphery sets axle housing, axle housing one end periphery sets brake drum component, the junction of brake drum component and jackshaft sets sealing ring, brake drum component is connected by the sealed circle of stripped nut component with jackshaft, the end face on jackshaft top sets half axle bolt with the junction of brake drum component, the both sides in brake disc, brake disc are set to be correspondingly arranged brake block respectively on the inside of brake drum component.
Axially arranged pass back-up ring, bearing two, bearing one successively between brake drum component and axle housing.
Bearing one is set up in parallel with bearing two.
The beneficial effects of the utility model are：Pass back-up ring can prevent two bearing's looseness being set up in parallel or landing；Stripped nut component can prevent brake drum component from loosening or sliding, and strengthen vehicle security energy, while stripped nut component carrying sealing ring is combined with jackshaft prevents axle housing component gear oil seepage, so as to play sealing function；Conventional independent axes bearing is cancelled, security performance is improved using disjunctor brake drum component.
Motor tricycle is when bearing weight by all Action of Gravity Field on the brake drum and the axle housing component, so as to which power is transmitted in into semiaxis driving motor tricycle traveling, eliminate load of the jackshaft to load-carrying, operational efficiency is improved, jackshaft service life is greatly increased, simultaneously, shearing force and impulsive force are scattered on axle housing when bearing mutation, avoid jackshaft bear mutation when shearing force and impulsive force, prevent half axle fracture, it is to avoid the potential safety hazard such as flywheel.Simple in construction, weight loss effect substantially, is adapted to promote the use of.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is, general assembly structural representation；
In Fig. 1：Jackshaft 1, axle housing 2, brake disc 3, brake drum component 4, stripped nut component 5, half axle bolt 6, bearing 1, bearing 28, pass back-up ring 9, sealing ring 10.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in the figure, the periphery of jackshaft 1 sets axle housing 2, one end periphery of axle housing 2 sets brake drum component 4, the junction of brake drum component 4 and jackshaft 1 sets sealing ring 10, brake drum component 4 is connected by the sealed circle 10 of stripped nut component 5 with jackshaft 1, the end face on the top of jackshaft 1 sets half axle bolt 6 with the junction of brake drum component 4, and the inner side of brake drum component 4 sets the both sides in brake disc 3, brake disc 3 to be correspondingly arranged brake block respectively.
Axially arranged pass back-up ring 9, bearing 28, bearing 1 successively between brake drum component 4 and axle housing 2.
