Welcome

Parts Services Holland Ltd. was founded in 2009 by four people who share their passion about two- and four wheel vehicles and in particular, the mechanical part.

By this passion and great interest in the so-called “green economy” we have joined forces and have developed in a creative and innovative way a new revolutionary gearbox.

The team was in agreement that the current traditional propulsion system, the data with various axes and many gears that was in the late 19th century en early 20th century could be improved. A major drawback of the system is that there are many different and relatively heavy parts needed, the return loss is very high and the engine power and release to the powered wheel are great.
In short:
- a costly investment with little return,
- a high wear and tear,
- relatively expensive in maintenance.

The team has managed to come up with a new revolutionary system.
The new system has been patented and has the following names:
CONTROLLED ROTATION SYSTEM” and “DUAL SLIDE GEAR

Explanation about CVT and CRS.

We received a lot of questions about the difference between the CVT-system and our CRS-system. We would like to explain to our visitors the difference between these systems. 

CVT

The CVT-system is based on the principle of two conical based pulleys.
These pulleys move towards and away from each other on an axle. Between the pulleys a belt is moving.
When the pulleys move towards each other, the belt moves outwards. When the pulleys move away from each other, the belt moves inwards. This generates a diameter either larger or smaller. Which will result into a larger or smaller gear.

In the picture below you see the visualization of this process.

CRS

The CRS-system is based on the principle of 2 disks with slide elements. These slide elements move inwards and outwards and create a larger or smaller diameter. The belt is moving over the disks. Which will result into a larger or smaller gear.

The slide elements are operated by a hydraulic enclosed system.

In the picture below you can see the visualization of this process.
