Abstract
The utility model discloses an anti-fracture rear axle for an electric tricycle, and belongs to the technical field of electric tricycles. The anti-fracture rear axle comprises a half shaft and an axle tube, wherein one end of the half shaft is provided with a spline joint, and the other end of the half shaft is provided with a brake hub, a shoe block and a brake disc; a bearing is arranged in the axle tube and between the axle tube and the half shaft; a positioning sleeve is sleeved on the half shaft between the bearing and the brake hub; an inner ring of the bearing is clamped by the positioning sleeve and a boss on the half shaft; the inner wall of the axle tube is provided with a clamp spring slot; a clamp spring is arranged in the clamp spring slot; and an outer ring of the bearing is clamped by the clamp spring and a step on the inner wall of the axle tube. The anti-fracture rear axle has the beneficial effects that: the bearing is positioned by using the positioning sleeve, and the clamp spring slot is not required to be formed on the half shaft, so that the problem of stress concentration is eliminated, the fracture of the half shaft of the rear axle is effectively prevented, and running safety of the electric tricycle is guaranteed.
Description
Technical field
The utility model relates to a kind of electric tricycle rearmost axle, belongs to the electro-tricycle technical field.
Background technology
At present, electro-tricycle is because its convenience, economy and the feature of environmental protection, and becomes widely used a kind of vehicle.But there is the unreasonable part of design in the prior electric tricycle rear axle: the bearing between rear axle shaft and the bridge tube mainly leans on the jump ring location on the semiaxis, promptly must on semiaxis, make the jump ring groove; Its defective is that semiaxis and bearing produce stress concentration easily in jump ring groove position in operation process; Thereby cause semiaxis to damage even fracture; Bring potential safety hazard for going of electro-tricycle, influence the person and safety traffic, to the quality of electro-tricycle with cause negative effect service life.
Summary of the invention
In order to overcome the weak point of above-mentioned prior art, the utility model provides a kind of electro-tricycle anti-fracture back axle, adopts the locating bush location bearing, thereby has eliminated problem of stress concentration, effectively prevents the semiaxis fracture, guarantees the electro-tricycle traffic safety.
The utility model is realized through following technical scheme: the anti-fracture back axle of a kind of electro-tricycle, and it comprises semiaxis, an end of semiaxis has spline joint; The other end of semiaxis is equipped with braking hub, hoof piece and brake disc; The middle part of brake disc is fixed with bridge tube, and bridge tube is sleeved on the described semiaxis, and described bridge tube is fixed with flange near an end of Formation of Axle Shaft Spline joint; Between bridge tube inside and the described semiaxis bearing is housed; Be set with locating bush on the semiaxis between described bearing and the braking hub, there is the jump ring groove position near bearing on the bridge tube inwall of locating bush homonymy, in the jump ring groove jump ring is housed; Be manufactured with boss on the semiaxis of the opposite side of described bearing; Boss and described locating bush block bearing cone, and are manufactured with step on the corresponding bridge tube inwall of semiaxis lug boss position, the outer ring that step and described jump ring block bearing.
Described bearing installation is on the position near brake disc on the described semiaxis.
The beneficial effect of the utility model is:
1, adopts the locating bush location bearing, need on semiaxis, not make the jump ring groove, thereby eliminate problem of stress concentration; Effectively prevent the rear axle shaft fracture; Strengthen the stability and the safety of operation, guarantee the electro-tricycle traffic safety, improve the quality and the service life of electro-tricycle.
2, simple in structure, be convenient to implement to promote, have good economic benefit and social benefit.
Description of drawings
According to accompanying drawing and embodiment the utility model is further specified below.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Among the figure, 1, flange, 2, semiaxis, 3, bridge tube, 4, bearing, 5, jump ring, 6, locating bush, 7, brake disc, 8, the hoof piece, 9, the braking hub.
The specific embodiment
Like Fig. 1, the anti-fracture back axle of a kind of electro-tricycle shown in Figure 2, it comprises semiaxis 2, and an end of semiaxis 2 has spline joint; The other end of semiaxis 2 is equipped with braking hub 9, hoof piece 8 and brake disc 7; The middle part of brake disc 7 is fixed with bridge tube 3, and bridge tube 3 is sleeved on the described semiaxis 2, and described bridge tube 3 is fixed with flange 1 near an end of semiaxis 2 spline joints; Between the inner and described semiaxis 2 of bridge tube 3 bearing 4 is housed, described bearing 4 is installed on the semiaxis 2 on the position near brake disc 7.
Be set with locating bush 6 on the semiaxis 2 between described bearing 4 and the braking hub 9; There is the jump ring groove position near bearing 4 on bridge tube 3 inwalls of locating bush 6 homonymies; Jump ring 5 is housed in the jump ring groove, is manufactured with boss on the semiaxis 2 of the opposite side of described bearing 4, boss and described locating bush 6 block the inner ring of bearing 4; Be manufactured with step, the outer ring that step and described jump ring 5 block bearing 4 on corresponding bridge tube 3 inwalls of semiaxis 2 lug boss position.Like this, need on semiaxis 2, not make the jump ring groove, just can effectively locate, thereby eliminate problem of stress concentration, effectively prevent the rear axle shaft fracture, guarantee the electro-tricycle traffic safety, improve the quality and the service life of electro-tricycle bearing 4.
