Quadricycles (L7e), also referred to as Heavy quadricycles, are defined by Framework Directive 2002/24/EC as motor vehicles with four wheels other than those referred to as light quadricycles, whose unladen mass is not more than 450 kg for passenger vehicles or 600 kg for vehicles intended for carrying goods not including the mass of batteries ...

2018年2月16日 · In a collaboration the fka, the School of Design Pforzheim and the material producer Hydro have developed the concept of a L7e-class micro car. The legal safety requirements for this vehicle class are low. The newly developed car’s passive safety, however, exceeds these requirements, inter alia thanks to the use of aluminum.

2017年11月27日 · L6e类和L7e类机动车的整备质量通常只有普通汽车的三分之一，当与汽车发生碰撞后，更易造成严重损伤。 德国保险协会的研究表明，在碰撞速度为45km/h的正面碰撞事故中，不同质量的汽车与L6e类机动车发生碰撞后双方车辆速度变化量差异很大，结果如图3所示 ...

2023年4月5日 · This study proposes an optimization methodology to design a monocoque sandwich structure under operating conditions for an L7e using a finite element model via HyperWorks. Woven fiberglass...

2019年9月4日 · The L7e vehicle class describes a small and light, battery-driven micro car. The requirements for such cars are: Under 3.7 meters in length, 1.5 meters wide, and 2.5 meters high; Lighter than 450 kilograms (excluding the battery system) Maximum continuous rated power 15 kW; Maximum speed of 90 kilometers per hour

根据欧盟规定，属于l6e的低速电动车,最高额定功率小于4千瓦,驾驶者年龄需满14周岁,申请驾照只需要简单的考试；属于l7e的低速电动车，最高额定功率小于15千瓦,驾驶者年龄需满16周岁,申请驾照需要5小时理论培训和驾驶理论考试。

2020年8月3日 · Excluding the battery, L7e cars have a weight limit of 450 kg. Using aluminium for the entire body combines low material weight with excellent structural properties and high energy absorption. A one-box design, with intensive use of closed-section aluminium profiles, enables optimal use of space and minimizes production costs.

2019年6月14日 · In the Next Generation Car project, the DLR Institute for Vehicle Concepts has developed a vehicle concept based on the L7e category with a body weight of just 90 kg. The structural concept consists largely of hybrid materials in sandwich construction. The article presents the results of the crash tests of two car bodies.

the L7e classification. New solutions are to be developed to solve the conflict of objectives between guaranteeing the resid - ual space at small outer vehicle dimensions and the prescribed weight limit. The car body material aluminum shows the poten - tial to combine a low specific material weight•with good structural properties and

Structural components of the L7e vehicle finite element model. [...] An electric heavy quadricycle, categorized as an L7e vehicle, is an alternative solution for sustainable mobility with a...
