Description

Device for maintaining the required air pressure in vehicle tires.

State of the art

The checking and maintenance of the air pressure in vehicle tires specified by the vehicle manufacturer is usually ensured by the driver (or persons authorized to do so). The air pressure is checked at random or fixed intervals and adjusted to the specified value if necessary.

problem

Often, these maintenance tasks are neglected, resulting in greater wear than necessary, unnecessary costs and, above all, an increased burden on the environment, both through increased fuel consumption and through increased production costs for vehicle tires.

Solution

This problem is solved by ensuring that the device maintains the required air pressure regardless of maintenance work.

Benefits achieved

By always setting the correct air pressure on all of a vehicle's tires, driving safety is increased, fuel consumption is reduced and the burden on the environment is reduced

Device for maintaining the required air pressure

An exemplary embodiment of the invention is explained with reference to Figures 1 to 4. They show:

Fig. 1 All essential components of the device Fig. 2 Vehicle tire and rim with position of the device

Fig. 3 the device in the position of rest and uniform movement.

Fig. 4 the device under the influence of negative acceleration

The main components of the device are described in Figure 1.

1 housing

2 sledges

3 pressure cylinders

Control valve
Return spring

6 Pressure line to vehicle tire

7 Ventilation valve

11 Push rod

12 pistons

Figure 2 describes the position of the device on the rim.

8 vehicle tires

9 Rim

10 Location of the device

The device uses the kinetic energy that occurs during braking by converting the mass inertia of the slide 2, which is mounted in the housing 1, into gas pressure in the pressure cylinder 3.

The control valve 4 passes the provided pressure to the pressure line to the vehicle tire 6 if the tire pressure is below the specified value.

When the braking process is completed, the return spring 5 ensures that the slide 2 returns to its original position. The ventilation valve supports this process.

The device is mounted on the rim 9, the position of the device 10 is determined from the mass, pressure and path conditions.

Contrary to the linear representation of the device, a radial arrangement of the components around the axis is recommended in order to increase the efficiency.
