Abstract
A chassis dynamometer for motorcycles with a combustion engine, having a mounting unit, at least one fastening unit, an operating unit, a control unit and a roller for recording the peripheral speed of a motorcycle rear wheel is disclosed. The chassis dynamometer has a flow unit a drive unit, a diffuser and an outflow unit arranged downstream of the diffuser in the direction of flow where the diffuser and outflow unit form a flow channel carrying gas in the operating state, wherein the diffuser can be driven by the drive unit, where the control unit controls the drive unit as a function of the peripheral speed of the roller in such a way that a speed of the gas emerging from the outflow unit in the operating state is substantially equal to the peripheral speed at least from a peripheral speed of 150 km/h.
Claims9
A chassis dynamometer (1) for motorcycles with a combustion engine, comprising:
- a mounting unit (2);
- at least one fastening unit (3);
- an operating unit (4);
- a control unit (5);
- a roller (6) for recording the peripheral speed of a motorcycle rear wheel;
- and
- a flow unit (7), which in turn has comprises:
- a drive unit (8);
- a diffuser (9);
- and
- an outflow unit (10) arranged downstream of the diffuser (9) in the direction of flow,
- wherein the diffuser (9) and outflow unit (10) form a flow channel carrying gas in the operating state, wherein the diffuser (9) is configured to be driven by the drive unit (8), wherein the control unit (5) controls the drive unit (8) as a function of the peripheral speed of the roller (6) in such a way that a speed of the gas emerging from the outflow unit (10) in the operating state is substantially equal to the peripheral speed at least from a peripheral speed of 150 km/h.
A method for the inflow of gas towards a motorcycle with a combustion engine on a chassis dynamometer (1), having the steps:
- stationary acceleration of the motorcycle on the chassis dynamometer (1) and measurement of the peripheral speed of the rear wheel of the motorcycle;
- generating a flow of gas towards the motorcycle, wherein the gas is accelerated and compressed such that its speed corresponds to the peripheral speed of the rear wheel;
- and further having at least one of the following steps:
- generating a laminar flow of the inflow gas after the gas has been accelerated and compressed;
- filtering the gas before the gas is accelerated and compressed;
- generating control signals for a device for accelerating and compressing the gas and controlling a drive unit (8) for accelerating and compressing a gas as a function of the peripheral speed of the rear wheel;
- and
- positioning the gas flow in relation to the motorcycle on the chassis dynamometer.
