Abstract
The utility model relates to a reinforced aluminum alloy rear wheel of an electric bicycle. The reinforced aluminum alloy rear wheel of the electric bicycle is composed of a wheel axle, spokes and a rim which are formed into a whole through pressure casting, and the wheel axle, the spokes and the rim are made of aluminum alloy. The spokes are evenly distributed on the outer edge of the wheel axle in the radial direction and are integrated with the wheel axle, the rim is integrated with the spokes coaxially and is arranged on the outside of the spokes, a tyre is mounted on the rim, the wheel axle is connected with a transmission shaft of the electric bicycle, and one reinforcing through hole is formed in each spoke. According to the reinforced aluminum alloy rear wheel of the electric bicycle, the reinforcing through holes are formed in the spokes through pressure casting according to the stress flow faces of the spokes, therefore, the whole intensity of the wheel is improved effectively, the electric bicycle is light, the consumption of batteries is reduced, and a rider can ride the electric bicycle safely.
Description
Technical field
The utility model belongs to electric automobiles, relates to the wheel of battery-driven car, especially a kind of heavier-duty battery-driven car aluminum alloy trailing wheel.
Background technology
At present, battery-driven car is light because of it, it is energy-conservation fast to reach, and popularization and application is among people's life.Because battery-driven car speed is very fast, so wheel need possess higher intensity, also needs light simultaneously.Existing battery-driven car wheel is made of wheel rim, spoke and wheel shaft, and spoke is the support stressed member of supporting wheel shaft and wheel rim, and normally many spokes by radial equipartition constitute, and the spoke of similar bicycle designs that comparatively dullness is not attractive in appearance; The most important thing is that intensity is relatively poor, weight is heavier, has influenced the battery-driven car self speed, causes the battery-driven car deadweight bigger, the electric energy of waste battery.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the heavier-duty battery-driven car aluminum alloy that a kind of modern design is attractive in appearance, intensity is high, weight is lighter trailing wheel is provided.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of heavier-duty battery-driven car aluminum alloy front-wheel, wheel shaft, spoke and the die casting of wheel rim one by aluminum alloy material form, the outer rim radial equipartition one of wheel shaft is shaped on spoke, coaxial one is shaped on wheel rim outside spoke, tire is installed on the wheel rim, wheel shaft is connected with the transmission shaft of battery-driven car, it is characterized in that: all be shaped on one and strengthen through hole on each spoke.
And described reinforcement through hole is the circular arc through hole.
Advantage of the present utility model and beneficial effect are:
1, this wheel adopts the die casting mode to be shaped on the reinforcement through hole according to its stressed flow surface on spoke, has effectively improved the bulk strength of wheel, has guaranteed the safety that Electrical Bicycle is ridden.
2, this wheel has alleviated the weight of spoke by be shaped on the reinforcement through hole at spoke, has alleviated the own wt of wheel then, makes battery-driven car light, is convenient to people and moves, and has prolonged the battery consumption amount simultaneously.
3, this wheel design science, novel and beautiful, simple in structure, intensity is higher, and weight is lighter, is the regeneration product of existing battery-driven car wheel, has higher market application foreground.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of heavier-duty battery-driven car aluminum alloy trailing wheel, wheel shaft 4, spoke 2 and wheel rim 1 one die casting by aluminum alloy material form, and the outer rim radial equipartition one of wheel shaft is shaped on spoke, and coaxial one is shaped on wheel rim outside spoke, tire is installed on the wheel rim, and wheel shaft is connected with the transmission shaft of battery-driven car.
Innovative point of the present utility model is:
All be shaped on one and strengthen through hole 3 on each spoke, this reinforcement through hole is beneficial to the metallographic structure that improves spoke, improves the intensity of spoke, has alleviated the weight of spoke simultaneously.
Described reinforcement through hole is the circular arc through hole.
Claims (2)
1. heavier-duty battery-driven car aluminum alloy trailing wheel, wheel shaft, spoke and the die casting of wheel rim one by aluminum alloy material form, the outer rim radial equipartition one of wheel shaft is shaped on spoke, coaxial one is shaped on wheel rim outside spoke, tire is installed on the wheel rim, wheel shaft is connected with the transmission shaft of battery-driven car, it is characterized in that: all be shaped on one and strengthen through hole on each spoke.
