Abstract
The utility model relates to an electric bicycle aluminum alloy rear wheel which is formed by an aluminum alloy wheel shaft, spokes and a rim in an integral pressure-casting mode. The integrated spokes are evenly distributed on the periphery of the wheel shaft in the radial direction, and the rim is coaxially and integrally arranged outside the spokes. A tyre is arranged on the rim, and the wheel shaft is connected with a power shaft of an electric bicycle. Reinforcing grooves are symmetrically formed in the inner face and the outer face of two sides of each spoke in a pressure-casting mode. The reinforcing grooves are formed in the inner face and the outer face of two sides of each spoke in the pressure-casting mode, so that the integral strength of wheels is effectively improved, the weight of the spokes is reduced, the electric bicycle is made to be lighter, and consumption time of a battery is prolonged. Safety of riding on the electric bicycle is guaranteed, and good market application prospects are achieved.
Description
Technical field
The utility model belongs to electric automobiles, relates to the wheel of battery-driven car, especially a kind of 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 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 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 dynamical axis of battery-driven car, it is characterized in that: all symmetry is suppressed strengthening groove on inside and outside of spoke both sides.
And described strengthening groove strengthening groove is on spoke, and is and similar to the outline of spoke.
Advantage of the present utility model and beneficial effect are:
1, this wheel adopts the die casting mode all to be suppressed with strengthening groove in the interior outside of spoke both sides, has effectively improved the bulk strength of wheel, has guaranteed the safety that Electrical Bicycle is ridden.
2, this wheel is suppressed with strengthening groove by the interior outside in the spoke both sides, has alleviated the weight of 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 battery-driven car aluminum alloy trailing wheel, wheel shaft 4, spoke 3 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 dynamical axis of battery-driven car.
Innovative point of the present utility model is:
All symmetry is suppressed strengthening groove 2 on inside and outside of spoke both sides, and this strengthening groove has improved the metallographic structure of spoke, has strengthened the degree of firmness of aluminum alloy, and then has improved the intensity of spoke, has alleviated the weight of spoke simultaneously.
In the present embodiment accompanying drawing, shown strengthening groove is on spoke, and is and similar to the outline of spoke, farthest to gain in strength.
Claims (2)
1. 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 dynamical axis of battery-driven car, it is characterized in that: all symmetry is suppressed strengthening groove on inside and outside of spoke both sides.
2. battery-driven car aluminum alloy trailing wheel according to claim 1 is characterized in that: described strengthening groove strengthening groove is on spoke, and is and similar to the outline of spoke.
