Description

Technical Field

[0001] The utility model relates to the technical field of tricycle frames, in particular to a novel load-bearing frame structure of an electric tricycle. Background Art

[0002] As is well known, the function of the frame is to support and connect each assembly of the vehicle, keep each assembly in a relatively correct position, and bear various loads inside and outside the vehicle. The frame must have sufficient strength and stiffness to bear the load of the vehicle and the impact transmitted from the wheels. It can protect passengers from being injured and the vehicle from being damaged.

[0003] When driving at high speed on the road, it is generated, and its size is related to the vertical vibration acceleration, and also related to the size and distribution of the static load on the frame. This kind of load-bearing frame generates bending deformation. When the vehicle is driving on an uneven road, the front and rear wheels of the vehicle are no longer in the same plane. The skew-symmetric dynamic load causes the frame and the body to tilt together. Its degree depends on the unevenness of the road and the stiffness of the frame and the suspension. This kind of load causes the frame to generate torsional deformation. There are also other loads. When the vehicle brakes or accelerates, the load moves. When turning, a lateral inertial force will be generated, causing local torsional forces on the parts installed at different positions on the frame.

[0004] With the progress of technology, those materials that were previously only used in aircraft and military applications are gradually entering the civilian market. For example, aluminum alloy and titanium alloy, which have a lower density than steel. Especially the emergence of high-strength steel has greatly reduced the weight of the frame. In some parts where only steel can be used, high-strength steel plates can be used to reduce the thickness of the steel plates, thereby reducing the weight. Therefore, a novel load-bearing frame structure of an electric tricycle is proposed in response to market demand. Content of the Utility Model
