In order to develop better products, it is sometimes necessary to start over from the beginning. To be successful with this, some basic research is needed. For Onspot, acceleration tests are something that is carefully analyzed. Read more here.
Onspot is mounted in one of the toughest places on a vehicle. Screwed on with a steel plate on the rear axle. Not even the vehicle's suspension provides any relief as the automatic snow chain system is fitted before it has any effect. Constantly exposed to dirt, water, ice and snow from the road.
Part of the system is the vehicle bracket itself. It is exposed to a constant influence on the movements of the vehicle and the condition of the road. Constantly shaking and moving in different directions. In addition, an Onspot cylinder with arm and chain wheel sits on it.
The rear axle of moves and behaves in different ways on different vehicles. On a heavy truck, with a total weight of over 16 tons, it moves more slowly in height due to its own weight and mass compared to the rear axle of a 3.5 ton light truck. The lighter vehicle has a smaller and lighter rear axle. It moves faster verticaly than a heavy rear axle does. They have different frequencies in the movements up and down. This affects the durability of a bracket.
To understand how different vehicles behave, Onspot has always performed different types of tests and tests. All to understand the basic physics and thus be able to make more sustainable products. A product that lasts a long time, preferably the entire life of the vehicle, is best from an environmental and sustainability point of view.
Recently, so-called acceleration tests were performed with Onspot. Then you measure the frequency with which an Onspot moves vertically when it is mounted on a vehicle. This is done with accelerometers mounted on test vehicles. These transfer the movements to different graphs. These graphs are translated into a movement pattern that is then used in shake-tests in the test lab at Onspot.
Since it is the movement vertically that affects a vehicle brackett the most, it is important to have the knowledge about this.
This time, the tests were performed with a smaller van. The test equipment is mounted and then driven lap after lap on a carefully selected circuit. The circuit contains many different types of roads and surfaces. The purpose has been to understand how a vehicle with an individually sprung drive shaft behaves. If there is any difference from one with a rigid rear axle.
The tests have exceeded expectations well. The results will be of great benefit to the development department in the development of new vehicle brackets. Demand for Onspot is constantly increasing. More vehicle categories are requested by customers and users as the system actually solves the problem of poor grip by increasing the friction to the road surface. Feel free to read more about this in the blog "What is traction, friction and grip?".
