Abstract
A double-bearing weight reduction method of a full-suspension rear axle is composed of a transmission half axle, an axle housing, a brake disc, a drum brake component, a locking round nut assembly, half axle nuts, a first bearing, a second bearing, a hole pattern check ring and a sealing ring. When a motor tricycle is loaded with weight, all the weight is acted on the drum brake and the axle housing component, so that force is transmitted to the half axle to drive the motor tricycle to travel, the load of the transmission half axle to the carrying weight is removed, thus operating efficiency is improved, and the service life of the transmission half axle is greatly prolonged. Meanwhile, accidental change occurs, shear force and impact force are dispersed onto the axle housing, the transmission half axle is prevented from bearing the shear force and the impact force during accidental change, half axle rupture is avoided, and the potential risks like a flywheel are also avoided. The structure is simple, the weight reduction effect is obvious, the safety coefficient for drivers and passengers is improved obviously, and the double-bearing weight reduction method of the full-suspension rear axle is suitable for popularization and application.
Description
Technical field
The present invention relates to bicycle for old people vehicle bridge field, especially a kind of duplex bearing weight losing method of full suspension back axle.
Background technology
At present, motorcycle rear axle is tapered configuration because simple in structure, easy to operate, travel flexibly, the convenient use, price is lower, deeply is subjected to vast old client's love and esteem, going out rides instead of walk or lies fallow use very convenient.But, because structure design is simple, the car back axle adopts single-bearing, brake wheel is after bearing gravity, power is directly passed for to bearing, pass for to jackshaft through bearing, the suffered various stress of the part of each transferring power are far longer than other positions of transmission system, easily cause the damage of bearing again, when in vehicle is being advanced, occurring jolting, jackshaft has born most of load weight, changes in various angles under the effect of power, and the transmission resistance of vehicle and loss are increased, make the Efficiency Decreasing of mechanical movement, the concentricity accuracy rate of axle housing and jackshaft is not high, thereby causes the jackshaft fracture, causes the flywheel accident.
Number of patent application is 201020669553.3 to have announced a kind of Integral motor-driven axle of electric vehicle, and brake wheel is directly delivered to after bearing gravity on the jackshaft, and long-term use easily causes the fracture of jackshaft.
In view of the foregoing, invent out a kind of duplex bearing weight losing method of full suspension back axle now.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art; a kind of duplex bearing weight losing method of full suspension back axle is provided; brake wheel is after bearing gravity; gravity is passed for to axle housing by duplex bearing; thereby protected jackshaft; prolong the service life of jackshaft, avoided the generation of flywheel accident.
The present invention adopts following technical scheme to achieve these goals: a kind of duplex bearing weight losing method of full suspension back axle is by jackshaft, axle housing, brake disc, brake wheel assembly, stripped nut assembly, half axle bolt, bearing one, bearing two, the pass back-up ring, seal ring consists of; Motor with motor-tricycle when bearing weight with all Action of Gravity Fields above the brake wheel assembly; after the brake wheel assembly is stressed the gravity going down is arrived whole brake wheel assembly; stripped nut assembly and seal ring are fixed on the brake wheel assembly on the jackshaft; the brake wheel assembly passes gravity on the bearing one that is set up in parallel and bearing two to the center; in the bearing rotary process, pass for arriving bearing inner sleeve through roller after bearing one and bearing two overcoats are stressed; the inner sleeve of bearing one and bearing two passes power for and is distributed on the axle housing; axle housing is in the periphery of jackshaft; axle housing has born whole gravity of motor-tricycle, and jackshaft does not bear gravity under the protection of axle housing.
Half axle bolt is fixed on the brake wheel assembly on the end face of jackshaft, makes brake wheel assembly and bearing one and bearing two tight pressings.
Bearing one and bearing two inner sleeves and the tight fit of axle housing, pass back-up ring prevent bearing and bearing two loosening or landings.
During brake, the brake facing of both sides is subjected to the spring tension effect to the axle housing application of force in the brake disc, and axle housing is stressed to be contacted with jackshaft, makes the jackshaft slow-down or stops.
The invention has the beneficial effects as follows: motor-tricycle when bearing weight with all Action of Gravity Fields on described brake wheel and described axle housing assembly, thereby power is transmitted in semiaxis driving motor-tricycle travels, removed the load of jackshaft to load-carrying from, improve operating efficiency, greatly increase jackshaft service life, simultaneously, when bearing sudden change, shearing force and impulsive force are scattered on the axle housing, shearing force and impulsive force when avoiding jackshaft to bear sudden change, prevent half axle fracture, avoided the potential safety hazards such as flywheel.Simple in structure, weight loss effect is obvious, and driver and crew's safety factor is obviously improved, and is fit to promote the use of.
Description of drawings
