Abstract
The utility model discloses a child car wheel connection structure, which comprises a car axle and wheels at the two ends of the car axle, wherein one wheel is in key connection with the car axle; the other wheel is embedded with a rolling bearing; and the rolling bearing is matched with the car axle. The child car wheel connection structure is simple in structure and more flexible for making a turn; the wheels can be more flexibly operated; and the service life of the wheels can be prolonged.
Description
Technical field
The utility model relates to a kind of Wheel of children cart connection structure, belongs to wheel shaft and makes up the field.
Background technology
Existing children's battery car driving system, make the rear axle revolution by the chain transmission, two-wheeled is key with axletree and is connected, its shortcoming is: two-wheeled is that key is connected with axletree, all as driving wheel, must take turns during turning with ground and produce cliding friction after wheel movement, turn radius is large, understeer is lived, the wheel wear block.
The utility model content
The utility model is intended to provide a kind of and turns flexibly, the little Wheel of children cart connection structure of wheel wearing and tearing.
The purpose of this utility model can reach by following measures: a kind of Wheel of children cart connection structure, comprise the wheel at axletree and axletree two ends, and a described wheel is connected with the axletree key, and another wheel is embedded in antifriction-bearing box, and antifriction-bearing box coordinates with axletree.
The technique scheme difference with the prior art is: compare two wheels all as driving wheel, the utility model only designs a driving wheel, the another one wheel connects axletree by antifriction-bearing box, as flower wheel, during turning and ground produces friction of rolling, rolling frictional resistance is little, and wheel is handled more flexible, the wheel longer service life.
Further, described key is connected to flat key and connects, and the manufacturing of key connection structure is simple, and is with low cost.
The utility model is simple in structure, turns more flexible, and wheel is handled more flexible, can extend wheel life.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model Wheel of children cart connection structure embodiment.
The specific embodiment
With reference to Fig. 1, a kind of Wheel of children cart connection structure comprises the wheel at axletree 1 and axletree 1 two ends, and wherein left wheel 21 is connected with axletree 1 flat key, and right wheel 22 is embedded in antifriction-bearing box 3, and antifriction-bearing box 3 coordinates with axletree 1.
During wheel work, the left wheel 21 that is connected with axletree 1 flat key is installed the right wheel 22 of antifriction-bearing box 3 as flower wheel as driving wheel, and driving wheel drives flower wheel and rotates, and rolling frictional resistance is little, and wheel is handled more flexible, the wheel longer service life.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. Wheel of children cart connection structure comprises the wheel at axletree and axletree two ends, and it is characterized in that: a described wheel is connected with the axletree key, and another wheel is embedded in antifriction-bearing box, and antifriction-bearing box coordinates with axletree.
2. Wheel of children cart connection structure according to claim 1 is characterized in that: described key is connected to flat key and connects.
