专利摘要:
The fifth wheel (3) of an articulated vehicle comprising the coupling between a semi-trailer (2) and a tractor (1) is provided with measuring apparatus for measuring forces imparted from the semi-trailer. The apparatus comprises a sensing device (5) for measuring horizontal loads (AD), and a sensing device (6) for measuring vertical loads (W). The signals from the sensing devices (5) and (6) are fed into an electronic controller (26), in turn to cause the brakes (27) on the trailer (2) to be applied to achieve balanced braking, anti-lock control, and traction control of the wheels. We can therefore use a tractor fitted with a braking system of the brake-by-wire type with a conventional semi-trailer, without modifications to semi-trailer or to the braking components of the semi-trailer.

Claims (11)
[1]
Claim
1. The brake system for an articulated vehicle in which the tractor is connected to the semi-trailer via a fifth wheel coupling device, comprising a measuring device that provides control signals to a pressure regulator in the brake drive and includes a sensor for measuring forces depending on the weight of the semi-trailer and acting essentially in vertical plane perpendicular to the horizontal plane on the fifth wheel coupling device including a towing plate mounted on the tractor frame by means of an explode on the sides of the supports with the possibility of a limited swing of 55 around the transverse axis perpendicular to the main longitudinal axis of the tractor, characterized in that, in order to increase the braking efficiency, the measuring device is equipped with a sensor for measuring forces opposite to 5 1757452 6 directions in the general horizontal plane, depending on the relative acceleration or deceleration between the tractor and the trailer, issuing control signals 5, independent of the signals of another sensor. ''
[2]
2. The system according to claim 1. characterized in that it is equipped with an electronic controller 10 that reads the signals of the sensors of the measuring device and generates electric currents supplied to the pressure regulator in the brake drive of the semi-trailer.
[3]
3. The system according to claim 1 or 2, which is related to the fact that the towing plate is connected to the supports by means of fastening nodes connected to it by coaxial pins, one sensor is installed at one support, and the other sensor is at another support.
[4]
4. The system according to claim 3, I distinguish between the one and the other. that each fastener assembly includes an elastic device. 25
[5]
5. A system according to claim 3 or 4, characterized in that one mounting unit includes a first-type lever acting on the first sensor, and the other mounting unit includes a third-type lever acting on the second sensor.
[6]
6. The system according to p. 5, characterized in that the levers are mounted on supports with the possibility of swinging on the yards, limited by elastic devices.
[7]
7. The system according to claim 6, with the fact that at least one elastic device
15 The swarm is made in the form of a spring.
[8]
8. The system according to p. 6, characterized in that. that at least one elastic device is made in the form of a leaf spring.
20
[9]
9. The system of claims. 1-8, with the exception of the fact that the sensors are displacement sensors.
[10]
10. The system of claims. 1-8, characterized in that the sensors are load sensors.
