Definitions
- the invention relates to a motor vehicle with a body section and an electromechanical wheel brake according to the preamble of claim 1.
- Hydraulic wheel brakes are connected to the body via a rigid brake line and to the wheel housing via a flexible brake hose.
- the coupling point between these two sections is a hydraulic screw connection which, because of its robust nature, can be placed in the wheel housing or even on the underbody of the vehicle. There it is exposed to adverse environmental conditions such as dirt, moisture, ice and falling rocks. It happens that during a technical vehicle inspection, hairline cracks are found in the surface of the brake hoses. Then the brake hoses must be replaced. It is assumed that there will be corresponding regulations for the replacement of defective lines for electrical lines to the brake actuators of new types of wheel brakes.
- a motor vehicle comprising a chassis and a body section, which delimits a wheel housing area from an interior area of the body, wherein a wheel with an associated electromechanical wheel brake is arranged on the side of the wheel housing area, the electromechanical wheel brake being connected to an electronic control and regulating unit via an electrical line of the motor vehicle can be connected, the electrical line comprising a first line section in the wheelhouse area and a second line section in the body interior area, wherein the first and the second line section are connected to one another via an electrical connection device which is arranged in the interior area of the body.
- the advantage of the invention lies in a body-fixed connection of the electrical line of the electromechanical wheel brake to the electronic control and regulation unit of the motor vehicle, which is arranged in a protected area of the vehicle body, which is atmospherically ventilated and sealed against the wheel housing.
- electrical connections are not as robust as their hydraulic counterparts. Such connections typically have cavities into which water and dirt must not penetrate.
- the invention thus protects the electrical connection device for the electrical line of an electromechanical wheel brake in the interior body area from environmental influences such as moisture, water, snow, mud and stone impact. This arrangement increases the functional reliability of the electrical line.
- the electrical connection device is preferably detachable.
- the detachable electrical connection device is particularly preferably designed as a plug connection or a clamp connection.
- the detachable type of connection has the advantage that in the event of a defect, the line on the wheel housing side is replaced and the line on the body side is retained.
- the first line section is accommodated via a seal on the body section.
- the seal is made of an elastomeric material.
- One end of the first line section can be pushed through an opening in the body section via the elastomeric seal and connected to the second line section via the electrical connection device.
- the seal protects the electrical connection device from water and dirt, which is located in the wheel housing area.
- the elastomeric seal also makes it easier to repair a defective cable.
- the first line section includes a ventilation hose which leads from an actuator of the electromechanical wheel brake to the connecting device.
- the ventilation hose is preferably arranged within a casing of the first line section.
- the ventilation hose particularly preferably opens out into an opening which is provided on the connecting device.
- FIG. 1 shows a section of a motor vehicle.
- FIG. 1 shows a detail of a motor vehicle with a chassis 1 which, in the case of a self-supporting body, transitions into a body section 2 or, in the case of a non-self-supporting body, is connected to this.
- Body section 2 delimits a wheel housing area 3 from an interior area 4 of the body.
- a wheel 11 with an associated electromechanical wheel brake 5 is arranged in the area of the wheel housing 3 .
- Wheel 11 is connected to chassis 1 via a steering knuckle 13 and a wheel suspension 12 and stands on a roadway 14.
- Body section 2 is part of the motor vehicle body and, with its specially shaped wall, represents the wheel housing.
- Electromechanical wheel brake 5 is connected via an electrical line 6 and 7 to an electronic control and regulation unit 10 of the motor vehicle for activating wheel brake 5 .
- Electrical line is divided into a first line section 6 and a second line section 7 .
- the first line section 6 is arranged in the wheel housing area 3 .
- First line section 6 is designed to be flexible enough to withstand dynamic influences (bending, twisting, buckling) from wheel movements.
- First line section 6 leads from a connection point 15 on wheel brake 5 to a connection point 16 on body section 2.
- An electrical connection device 8 is provided at the connection point 16, by means of which the first and second line sections 6 and 7 are connected to one another.
- the electrical connection device 8 is arranged in the interior area 4 of the body. In other words, in an area within the vehicle that is protected from environmental influences.
- a seal 9 is provided at the connection point 16, by means of which an end region of the first line section 6 is held on the body section 2 in a sealing manner.
- the second line section 7 is arranged in the interior area 4 of the body.
- the second line section 7 leads from the electrical connection device 8 to the electronic control and regulation unit 10.
- Electromechanical wheel brake 5 is thus connected to the electronic control and regulation unit 10 via a detachable electrical connection device 8 that is secured against dirt in order to actuate it.
