Be it drinks, clothes, electrical appliances, the delivery directly to the house is in. This also applies to supermarkets. One of them left the RM Customs GbR build a small series of e-trikes to slow down traffic jams and help protect the environment. For more comfort and safety To steer make Brake cylinder of ACE Shock GmbH installed.

E-cargo bikes as an environmentally friendly alternative

Delivering goods by vans and trucks poses increasing problems for cities: the growing number of home deliveries is causing more and more congested streets. In addition to the actual journeys, there is also the task of finding a parking space. E-cargo bikes are available at one Delivery radius of 2 km as in this case, the more environmentally friendly and faster choice. Cooperation with Edeka

An initial cooperation between the company RM Customs from Kleve on the Lower Rhine and the local Edeka-Center Schroff confirms this. The cargo bike, tailor-made by RM Customs in an underfloor design, can be Top speed of 45 km / h Even on busy roads, it can often be used and, thanks to a small photovoltaic system, can even achieve a range of more than the standard 60 km when exposed to sunlight.

This means that, despite a storage volume of the equivalent of eight shopping baskets with a maximum total weight of 100 kg, the battery of the freight bike does not have to be recharged after just a few deliveries.

Kettcar for adults creates a range of up to 200 km

After all, the innovative cargo bike, dubbed the Ecomobile, has one Fronthub motor and has an output of 2,3 kW with a maximum torque of 120 Nm, which is available to the supplier almost immediately from a standstill. A consumption of around 2,5 kWh per 100 km corresponds to 0,32 liters of petrol or 0,25 liters of diesel. If additional electricity is supplied by the photovoltaic system mentioned above, the range increases accordingly or it supports the charging process at the socket.

E-trike optimized with hydraulic brake cylinders

Before cooperating with Edeka, RM Customs already had one Prototype of his e-trike brought onto the road, reaching a speed of 25 km/h. During its development, the problem arose that the entire system rocked when there were potholes or sudden steering movements and the vehicle threatened to overturn. This was also a complaint from the TÜV. Since the further development reaches a top speed of 45 km/h, the company founders of RM Customs, Dr.-Ing. Marcel Rouenhoff and Dipl.-Ing. Markus Mühlberg, fix the unrest in the chassis.

A first try with Industrial gas springs did not meet the requirements. The second attempt was to turn to the gas spring team at ACE Schockdampfer GmbH. Innovative and high-quality gas pressure and gas tension springs are offered there. Based on positive experiences in applications in the leisure industry, the engineers at ACE in Langenfeld knew that their hydraulic brake cylinders would be even better suited to stabilizing vehicles than gas springs.

In addition to the automotive sector, industrial applications such as classic mechanical engineering, the electronics and furniture industries as well as the Medical Technology typical areas of application for these construction elements. Hydraulic brake cylinders are ideal for damping masses that swing back and forth.

Double-acting brakes

After considering all the key data, both sides decided to install components of this type HB-28-100-EE-PT. These hydraulic brake cylinders can be used as double or single-acting brakes. Their coated bodies in a slim design and the piston rods with a wear-resistant surface coating are features of high quality and durability.

As with all representatives of the HB family, the model used is a maintenance-freees, ready-to-install and closed system. The HB-28 is adjustable and, with a diameter of 28 mm and a stroke of 100 mm, delivers a variably adjustable pressure or pulling force of 30 to 3000 N.

This makes one Adjusting segment on the piston Easy adjustment is possible, with a large selection of attachments also making assembly easier.

After the solution found with the help of ACE worked well in the first two series of RM Customs e-trikes, it is currently running Development of the next generations. We are working on even more driving comfort, a larger trunk volume and a longer range. An undertaking that will certainly be successful given the ever-increasing demand for e-trikes.
