Description
技术领域：Technical field:
本实用新型涉及一种安装在电动车车把下的前电动车轮子。The utility model relates to a front electric wheel wheel installed under the handlebar of the electric vehicle.
背景技术：Background technique:
常规的安装在电动车车把下的前电动车轮子通常都是由轮辋、轮辐及轮毂构成；所述轮辐连接在轮辋内圈与轮毂外圈之间；所述轮毂呈圆柱形，且中间设有用来安装轴承的轴承安装孔。上述电动车轮子的工作原理是通过后驱动电动车轮子的带动，从而在地面摩擦力的作用进行转动。由于这种电动车轮子的驱动是靠其与地面的摩擦力来进行转动，因此，轮辐在电动车轮子中起着至关重要的作用，其强度参数的大小直接影响着电动车轮子的使用寿命，因此，轮辐的强度参数成为许多电动车轮子生产厂家首要考虑的问题。目前，用于电动车轮子上的轮辐通常是由多条单层辐条构成，虽然辐条的形状各式各样，但是，它们都有一个共同的特点，即每根辐条远离刹车装置安装孔的一端均是各自连接在轮辋内圈的不同位置，换句话说，每根辐条与轮毂内圈的连接处只受到一根辐条的作用力，这种结构大大影响了轮辐的强度，不同程度地缩短了电动车轮子的使用寿命。Conventional front electric wheel wheels installed under the handlebars of electric vehicles are usually composed of rims, spokes and hubs; the spokes are connected between the inner ring of the rim and the outer ring of the hub; There are bearing mounting holes for mounting bearings. The working principle of the above-mentioned electric wheel is to rotate under the action of ground friction by being driven by the rear-drive electric wheel. Since the wheel of this electric wheel is driven by its friction with the ground to rotate, therefore, the spoke plays a vital role in the wheel of the electric wheel, and its strength parameter directly affects the service life of the wheel of the electric wheel Therefore, the strength parameters of the spokes have become the primary considerations of many electric wheel manufacturers. At present, the spokes used on the wheels of electric vehicles are usually composed of multiple single-layer spokes. Although the spokes have various shapes, they all have a common feature, that is, the end of each spoke away from the mounting hole of the brake device. They are all connected to different positions of the inner ring of the rim. In other words, the connection between each spoke and the inner ring of the hub is only subjected to the force of one spoke. This structure greatly affects the strength of the spokes and shortens them to varying degrees. The service life of the electric wheel.
实用新型内容：Utility model content:
本实用新型要解决的技术问题是，提供一种保证轮辐用料更省的情况下，轮辐强度更强，使用寿命更长的电动车轮子。The technical problem to be solved by the utility model is to provide an electric wheel with stronger spoke strength and longer service life while ensuring less material used for the spokes.
本实用新型的技术解决方案是，提供一种具有以下结构的电动车轮子，它由轮辋、圆柱形轮毂及轮辐构成；所述圆柱形轮毂上设有轴承安装孔；所述轮辐包括若干对周向分布的辐条组；每对辐条组包括一根辐条I和一根辐条II；所述辐条I的形状与辐条II的形状相同；所述辐条I的一端连接在圆柱形轮毂左端面的边缘处；所述辐条II的一端连接在与圆柱形轮毂左端面边缘处相对应的圆柱形轮毂右端面边缘处；所述辐条I的另一端和辐条II的另一端同时连接在轮辋内圈的同一位置处；所述辐条I与辐条II之间为中空。The technical solution of the utility model is to provide an electric wheel with the following structure, which is composed of a rim, a cylindrical hub and a spoke; the cylindrical hub is provided with a bearing mounting hole; The group of spokes distributed in the direction; each pair of spoke groups includes a spoke I and a spoke II; the shape of the spoke I is the same as that of the spoke II; one end of the spoke I is connected to the edge of the left end face of the cylindrical hub ; One end of the spoke II is connected to the edge of the right end face of the cylindrical hub corresponding to the edge of the left end face of the cylindrical hub; the other end of the spoke I and the other end of the spoke II are simultaneously connected to the same position of the inner ring of the rim place; the spoke I and the spoke II are hollow.
采用以上结构后，与现有技术相比，本实用新型具有以下优点：与现有技术不同，本实用新型中的轮辐是由若干对周向分布的辐条组构成，而每对辐条组又包括一根辐条I和一根辐条II，由于辐条I和辐条II不但形状相同，而且它们未与圆柱形轮毂连接的一端同时连接在轮辋内圈的同一位置处，换句话说，本实用新型采用的是双层轮辐，每个轮辋内圈与辐条的连接处均可受到两根辐条的作用力即辐条I和辐条II和作用力，因此，本实用新型中轮辐的强度得到了较大的提高，从而延长了本实用新型的使用寿命；另外，由于所述辐条I与辐条II之间为中空，因此本实用新型用于轮辐的用料比较省，换句话说，在达到同等强度的情况下，本实用新型轮辐的用料要少于常规电动车轮子上轮辐的用料。After adopting the above structure, compared with the prior art, the utility model has the following advantages: different from the prior art, the spokes in the utility model are composed of several pairs of circumferentially distributed spoke groups, and each pair of spoke groups includes A spoke I and a spoke II, because spoke I and spoke II are not only identical in shape, and they are not connected to the same position of the inner circle of the rim at the same time at the end that they are not connected with the cylindrical hub, in other words, the utility model adopts It is a double-layer spoke, and the connection between the inner ring of each rim and the spoke can be subjected to the force of two spokes, that is, the force of spoke I and spoke II. Therefore, the strength of the spoke in the utility model has been greatly improved. Thereby prolonging the service life of the utility model; in addition, because the spoke I and the spoke II are hollow, so the utility model is used for the material of the spoke relatively economically, in other words, in the case of reaching the same strength, The materials used for the spokes of the utility model are less than those used for the spokes on the conventional electric wheel.
