Chassis Dynos allow to test vehicles and measure power without having to dismount the
engine. Power and torque available in the wheel, engine and losses in the transmission can
be measured. These dynos allow testing in the shop, avoiding street or road tests which
mean risk, difficulties and imprecise conclusions.
We build alternatives for cars, trucks, motorcycles, ATVs and karting, in inertial format, with electric or hydraulic brake and also combined.
Various models of chassis dynos are manufactured for these vehicles. All of them are very easy to assemble with portable structures that do not require installation. Operation is very simple and fast, with the latest technology data acquisition system that offer great precision and repeatability.
We manufacture different models according to type of vehicle and power to be measured. Inertial tests do not have a physical test limit, any vehicle can be mounted on the rollers and make an acceleration test. The limitation in these cases will be the quality of the measurement: as more power is tested, inertia must be higher, if it is not enough, the run will be too fast. In these cases the measurement will be inconsistent and not repetitive, with a significant margin of error.
Rolls have a special surface grip that avoids slipping and allows to reduce the load of the vehicle on the roller, minimizing heating and deformation. These dynos are also equipped with a pneumatic brake to stop the roller at the end of the tests and lock it for assembly and departure.
Below are presented different alternatives regarding diameter of the rollers, which is closely linked to the inertial moment and therefore to the equivalent mass of the rollers that the vehicle must "push".
