Description

STEERING ARRANGEMENT FOR A VEHICLE TECHNICAL FIELD The invention relates to a steering arrangement for a vehicle and a vehicle comprising such a steering arrangement.

BACKGROUND AND PRIOR ART Steering arrangements for vehicles, such as trucks, generally comprise a steering knuckle, which may be rotatably mounted in relation to a king pin. An angle sensor may be provided between the steering knuckle and the kingpin in order to calculate and monitor the angular position of the steering knuckle relative to the kingpin. Thus, the actual steering angle of the steered wheel may be calculated and monitored, which may be useful for controlling the driving conditions of the vehicle.

The king pin which may be fixed with respect to a chassis of the vehicle and the steering knuckle rotates with respect to a central longitudinal axis of the kingpin which may also be the rotation axis of the steering knuckle. At least one bearing element allows the pivoting movement of the steering knuckle with respect to the kingpin around the rotation axis. The bearing elements may be rolling bearings having rolling elements such as rollers, balls or needles. In order to protect the bearing elements from dirt and fluids a cover may be mounted on the steering knuckle at the end of the king pin for closing an internal volume filled with a lubricant. In order to detect the angular position of the steering knuckle with respect to the king pin an angle sensor may be mounted inside the internal volume of the cover.

Document WO-A1-2016/116150 discloses a steering assembly for an automotive vehide. A steering knuckle is pivotally mounted around a king pin and a sensor unit is arranged for sensing the angular position of the steering knuckle with respect to the king pin. A cover is mounted on the steering knuckle so as to close an internal vol ume in which an axial end part of the king pin may extend. The sensor unit is arranged in the cover and is connected to the king pin by means of axially extending tongues which cooperate in a sliding manner with a protruding portion of the king pin.

SUMMARY OF THE INVENTION The steering knuckle may be provided with a drum brake or a disc brake. Drum brakes may need more mounting space than disc brakes. A central longitudinal axis of the king pin and a central longitudinal axis of a spindle for a wheel arranged on the steering knuckle may intersect each other in an angle different from 90°. This result in that one of the end portions of the king pin may be situated closer to the wheel and thus also closer to the drum brake than the other end portion. Due to lack of space on vehicles provided with drum brakes there may be no space for arranging an angle sensor on that part of the king pin which is situated closest to the drum brake. Thus, there is a need to arrange an angle sensor at a king pin and a steering knuckle at a position where it is enough space for the angle sensor.

There is a need to further develop a steering arrangement for a vehicle which reduces mounting time and costs.

The object of the invention is therefore to further develop a steering arrangement for vehicles comprising an angle sensor which may be arranged at a king pin and a steering knuckle where it is enough space for the angle sensor. Another object of the invention is to develop a steering arrangement for a vehicle which reduces mounting time and costs.

These objects are achieved with the above-mentioned steering arrangement according to the appended claims.

It would be advantageous to achieve a steering arrangement for a vehicle overcoming, or at least alleviating, at least some of the above mentioned drawbacks. In particular, it would be desirable to enable a steering arrangement for a vehicle provided with an angle sensor which may be arranged at a king pin and a steering knuckle where it is enough space for the angle sensor. To better address one or more of these concerns, a steering arrangement for a vehicle having the features defined in the independent claims is provided.

According to an aspect of the invention the steering arrangement comprises a king pin, a steering knuckle which is pivotally mounted around the king pin, an angle sensor provided with a sensor shaft, which is connectable to the king pin, an angle sensor housing in which the angle sensor is arranged and which is connectable to the steering knuckle of the steering arrangement. An attraction element is arranged between the sensor shaft and the king pin, so that sensor shaft is connectable to an end portion of the king pin by means of an attraction force which is directed in the axially direction of the king pin and the sensor shaft.

Such steering arrangement enables the measurement of the steering angle at a top of the king pin regardless type of brake system used, i.e. drum or disc brake. It also facilitates mounting the angle sensor since there may be no need for using distance elements, such as shims, to achieve correct pre-tension of the bearings arranged between the king pin and the steering knuckle. This reduces mounting time and costs. Also, such steering arrangement enables enough space for the angle sensor at the king pin and the steering knuckle. By means of the steering arrangement, steering system compliance and steering angles are easily measurable on vehicles equipped with either disc or drum brakes. Flexibility and compliance issues can easily be detected and quantified by means of the steering arrangement. Steering effort measurements are made possible and also more accurate by means of the steering arrangement, since the steering angles are measured at a position close to the wheels instead of a position at the steering wheel. The steering arrangement could also be used as a substitute for currently used steering wheel angle sensor used in systems for stability control or in active steering applications for e.g. lane keeping, path following, autonomous vehicles and other such functionalities. The angle sensor may be connected to an electronic control device comprising a measurement unit, which enabling angle measurements.

The attraction element which is arranged between the sensor shaft and the king pin reduces the mounting time of the steering arrangement. The sensor shaft is connectable to the end portion of the king pin by means of the attraction force which is directed in the axially direction of the king pin and the sensor shaft. The attraction force may be sufficient for transmitting torque between the sensor shaft and the king pin. The torque may be exerted by the pivoting movement of the steering knuckle on the sensor shaft via sensing elements in the angle sensor. The king pin may be attached to the chassis of the vehicle and may of that reason not be rotatable. Since the sensor shaft may be connected to the king pin by means of the attraction element the sensor shaft cannot rotate. However, an angle sensor comprises sensing elements that may have a relative movement in order to detect the pivoting angle between the king pin and the steering knuckle. These sensing elements may be magnets, optical devices or conductive elements. Since the sensor shaft stands still and the sensing elements surrounding the sensor shaft rotates when the steering knuckle pivots for pivoting the wheels when steering and turning the vehicle, pivoting angle between the king pin and the steering knuckle may be detected.

According to the invention, the attraction element is a magnet. When a magnet is arranged between the sensor shaft and the king pin the mounting time of the steering arrangement may be reduced. The magnet may be arranged as a separate unit between the sensor shaft and the king pin. The sensor shaft and the king pin are made of a magnetic material, such as steel, so that the magnet can be connected to the sensor shaft and to the king pin by means magnetic attraction force. The end portion of the sensor shaft and the end portion of the king pin are connectable to the magnet by means of the magnetic attraction force which is directed in the axially direction of the king pin and the sensor shaft. The magnetism of the magnet may be so strong that the attraction force may be sufficient for transmitting torque between the sensor shaft and the king pin. The magnet may be a permanent magnet.

According to a further aspect of the invention the magnet may be provided with at least one conically shaped point, which may interact with a conically shaped indentation in the end portion of the king pin and/or in the end portion of the sensor shaft. The conically shaped point may be have a direction so that the magnet may be centred in relation to a longitudinal central axis of the king pin and/or the sensor shaft. The conically shaped indentation in the end portion of the king pin and/or in the end portion of the sensor shaft may have longitudinal central axis which coincides with the longitudinal central axis of the king pin and/or the sensor shaft. The magnet may be provided with two conically shaped points which are directed in opposite directions, so that one of the points is intended to be arranged in an a conically shaped indentation in the end portion of the king pin and the other point is intended to be arranged in a conically shaped indentation in the end portion of the sensor shaft.

According to a further aspect of the invention the magnet may be provided with at least one conically shaped indentation, which may interact with a conically shaped point arranged in the end portion of the king pin and/or in the end portion of the sensor shaft. The conically shaped indentation may be have a direction so that the magnet may be centred in relation to a longitudinal central axis of the king pin and/or the sensor shaft. The conically shaped point in the end portion of the king pin and/or in the end portion of the sensor shaft may have longitudinal central axis which coincides with the longitudinal central axis of the king pin and/or the sensor shaft. The magnet may be provided with two conically shaped indentations which are directed in opposite directions, so that one of the indentations is intended to accommodate a conically shaped point in the end portion of the king pin and the other indentation is intended to accommodate a conically shaped point in the end portion of the sensor shaft.

According to a further aspect of the invention the attraction element may be a magnet attached to the sensor shaft, so that the sensor shaft is connectable to the king pin by means of a magnetic attraction force from the magnet. The magnet may be attached to the sensor shaft by means of any suitable means such as threaded screw connection, a weld or an adhesive. When a magnet is attached to the sensor shaft the mounting time of the steering arrangement may be reduced. The sensor shaft and the king pin may both be made of a magnetic material, such as steel, so that the magnet can be connected to the king pin by means of a magnetic attraction force. The end portion of the king pin are connectable to the magnet by means of the magnetic attraction force which may be directed in the axially direction of the king pin and the sensor shaft. The magnetism of the magnet may be so strong that the attraction force may be sufficient for transmitting torque between the sensor shaft and the king pin. The magnet may be a permanent magnet.

According to a further aspect of the invention the magnet may be provided with a conically shaped point, which may interact with a conically shaped indentation in the end portion of the king pin. The conically shaped point may have a direction so that the magnet with the sensor shaft is centred in relation to a longitudinal central axis of the king pin. The conically shaped indentation in the end portion of the king pin may have longitudinal central axis which coincides with the longitudinal central axis of the king pin.

According to a further aspect of the invention the attraction element may be a magnet attached to the king pin, so that the king pin is connectable to the sensor shaft by means of a magnetic attraction force from the magnet. The magnet may be attached to the king pin by means of any suitable means such as threaded screw connection, a weld or an adhesive. When a magnet is attached to the king pin the mounting time of the steering arrangement may be reduced.

The conically shaped indentation in the end portion of the sensor shaft may have longitudinal central axis which coincides with the longitudinal central axis of the sensor shaft.

According to a further aspect of the invention a central longitudinal axis of the king pin and a central longitudinal axis of a spindle for a wheel arranged on the steering knuckle intersect each other in an angle different from 90° resulting in that one of end portions of the king pin may be situated at a larger distance from the wheel than the other end portion. This result in that one of end portions of the king pin may be situated closer to the wheel than the other end portion. However, according to the invention also an intersection of 90° between the central longitudinal axis of the king pin and the central longitudinal axis of the spindle is possible.

According to a further aspect of the invention the sensor shaft and the king pin are connectable to that end portion of the king pin which may be situated at a larger distance from the wheel than the other end portion of the king pin. The end portion of the king pin which may be situated closer to the wheel may not provide enough space between the wheel or a drum brake for arranging the angle sensor on that end of the king pin. However, the end portion of the king pin which may be situated at a larger distance from the wheel than the other end portion of the king pin provides enough space between the wheel or a drum brake for arranging the angle sensor on that end of the king pin.

At least one bearing allows the pivoting movement of the steering knuckle with respect to the kingpin around the rotation axis. The bearing may be a rolling bearing having rolling elements such as rollers, balls or needles. In order to protect the bearing from dirt and fluids the angle sensor housing may also constitute a cover for closing an internal volume filled with a lubricant for the bearing.

DETAILED DESCRIPTION OF THE DRAWINGS Fig. 1 schematically shows a side view of a vehicle 1 , provided with a steering arrangement 2 according to an embodiment. The vehicle 1 may be provided with driver and passenger compartment 4 arranged on a chassis 6 of the vehicle 1. Also, the vehicle 1 may be provided with a powertrain 8, which comprises an internal combustion engine 10, a gearbox 12, and a propeller shaft 14. The gearbox 12 may be connected to drive wheels 16 via a propeller shaft 14. The vehicle 1 may be a heavy vehicle, e.g. a truck or a bus. The vehicle 1 may alternatively be a passenger car. The vehicle 1 may be manually operated, remotely operated or autonomously operated. The steering arrangement 2 may be connected to front wheels 18 of the vehicle 1 and to a steering wheel 20 in the driver and passenger compartment 4. A turning motion of the steering wheel 20 will turn the front wheels 18 via the steering arrangement 2. Instead of, or together with the steering wheel 20, an electronic control arrangement 22 may be connected to the steering arrangement 2 for remotely or autonomously operation of the vehicle 1. The steering arrangement 2 may also be connected to the drive wheels 16 of the vehicle 1. Instead of, or in combination with the internal combustion engine 10, an electric engine 23 may be connected to the powertrain 8.

Fig. 2 shows the steering arrangement 2 according to a first embodiment. The steering arrangement 2 comprising a king pin 24 and a steering knuckle 26 which may be pivotally mounted on bearings 27 around the king pin 24. The pivoting angle between the king pin 24 and the steering knuckle 26, which also represents a steering angle of the steering arrangement 2 and the vehicle 1 , may be measured by means of a an angle sensor 28. The angle sensor 28 may comprise a sensor shaft 30 which may be connectable to the king pin 24. The angle sensor 28 may be arranged within an angle sensor housing 32, which also may constitute a cover for the bearings 27 arranged between the king pin 24 and the steering knuckle 26. The angle sensor housing 32 may be connectable to the steering knuckle 26 by means of threaded bolts 33. However, the sensor housing 32 it selves may be provided with threads, so that the sensor housing 32 is connected to threads arranged in the steering knuckle 26. The king pin 24, which may be fixed with respect to a chassis 6 of the vehicle 1 , and the steering knuckle 26 rotates with respect to a central longitudinal axis 34 of the kingpin which may also be the rotation axis of the steering knuckle 26. The bearings 27 allow the pivoting movement of the steering knuckle 26 with respect to the king pin 24 around the central longitudinal axis 34. The bearings 27 may be a rolling bearing having rolling elements such as rollers, balls or needles. In order to protect the bearing from dirt and fluids the angle sensor housing 32 may also constitute a cover for closing an internal volume filled with a lubricant for the bearings 27.

The central longitudinal axis 34 of the king pin 24 and a central longitudinal axis 36 of a spindle 38 for the front wheel 18 arranged on the steering knuckle 26 intersect each other in an angle different from 90° resulting in that one of the end portions 40 of the king pin 24 may be situated at a larger distance from the front wheel 18 than the other end portion 42. This result in that one of end portions 42 of the king pin 24 may be situated closer to the wheel 18 than the other end portion 40. The sensor shaft 30 and the king pin 24 are connectable to that end portion 40 of the king pin 24 which may be situated at a larger distance from the front wheel 18 than the other end portion 42 of the king pin 24. The end portion 42 of the king pin 24 which may be situated closer to the wheel 18 may not provide enough space between the wheel 18 or a drum brake 44 for arranging the angle sensor 28 on that end of the king pin 24. However, the end portion 40 of the king pin 24 which may be situated at a larger distance from the wheel 18 than the other end portion 42 of the king pin 24 provides enough space between the wheel 18 or a drum brake 44 for arranging the angle sensor 28 on that end portion 40 of the king pin 24.

The sensor shaft 30 may be connectable to an end portion 40 of the king pin 24 by means of an attraction force which may be directed in the axially direction of the king pin 24 and the sensor shaft 30. The attraction force may be generated by means of an attraction element 46 that may be arranged between the sensor shaft 30 and the king pin 24. The attraction force should be sufficient for transmitting torque between the sensor shaft 30 and the king pin 24. Torque may be exerted by the pivoting movement of the steering knuckle 26 on the sensor shaft 30 via sensing elements in the angle sensor 28. The king pin 24 may be attached to the chassis 6 of the vehicle 1 and may for that reason not be rotatable. Since the sensor shaft 30 may be connected to the king pin 24 by means of the attraction element the sensor shaft 30 cannot rotate. The angle sensor 28 comprises sensing elements 48 that may have a relative movement in order to detect the pivoting angle between the king pin 24 and the steering knuckle 26. These sensing elements 48 may be magnets, optical devices or conductive elements which are adjacent to or surround the sensor shaft 30. Since the sensor shaft 30 stands still and the sensing elements 48 rotates when the steering knuckle 26 pivots for pivoting the wheels 18 when steering and turning the vehicle 1 , pivoting angle between the king pin 24 and the steering knuckle 26 may be detected.

The attraction element may be a magnet 46, such as a permanent magnet 46. In fig. 2 the magnet 46 may be attached to the sensor shaft 30, so that the sensor shaft 30 may be connectable to the king pin 24 by means of a magnetic attraction force from the magnet 46. The king pin 24 may be made of a magnetic material, such as steel, so that the magnet 46 can be connected to the king pin 24 by means magnetic attraction force. The end portion 40 of the king pin 24 may be connectable to the magnet 46 by means of the magnetic attraction force which may be directed in the axially direction of the king pin 24. The magnetism of the magnet 46 may be so strong that the attraction force may be sufficient for transmitting torque between the magnet 46 and the king pin 24. The magnet 46 may be provided with a conically shaped point 50, which may interact with a conically shaped indentation 52 in the end portion 40 of the king pin 24. However, the magnet 46 may be provided with at least one conically shaped indentation 52, which may interact with a conically shaped point 50 arranged in the end portion 40 of the king pin 24. The conically shaped point 50 and indentation may be have a direction so that the magnet 46 may be centred in relation to a longitudinal central axis of the king pin 24 and the sensor shaft 30. The angle sensor 28 may be suspended in a resilient element 51 , such as springs, so that the conically shaped point 50 on the magnet may coincide with the conically shaped indentation 52 in the end portion 40 of the king pin 24 even though the centre lines of the conically shaped point 50 and the conically shaped indentation 52 do not coincide.

Fig. 3 shows the steering arrangement 2 according to a second embodiment. According to this embodiment the magnet 46 may be attached to the king pin 24, so that the king pin 24 may be connectable to the sensor shaft 30 by means of a magnetic attraction force from the magnet 46. The sensor shaft 30 may be made of a magnetic material, such as steel, so that the magnet 46 can be connected to the sensor shaft 30 by means of magnetic attraction force. The end portion of the sensor shaft 30 may be connectable to the magnet 46 by means of the magnetic attraction force which may be directed in the axially direction of the sensor shaft 30. The magnetism of the magnet 46 may be so strong that the attraction force may be sufficient for transmitting torque between the magnet 46 and the sensor shaft 30. The magnet 46 may be provided with a conically shaped point 50, which may interact with a conically shaped indentation 52 in the end portion of the sensor shaft 30. However, the magnet 46 may be provided with at least one conically shaped indentation 52, which may interact with a conically shaped point 50 arranged in the end portion of the sensor shaft 30. The conically shaped point 50 and indentation may be have a direction so that the magnet 46 may be centred in relation to a longitudinal central axis of the king pin 24 and the sensor shaft 30.

Fig. 4 shows the steering arrangement 2 according to a third embodiment. According to this embodiment the magnet 46 may be arranged as a separate unit between the sensor shaft 30 and the king pin 24, so that the sensor shaft 30 and the king pin 24 are connectable via the magnet 46 by means of a magnetic attraction force from the magnet 46. The sensor shaft 30 and the king pin 24 are made of a magnetic material, such as steel, so that the magnet 46 can be connected to the sensor shaft 30 and the king pin 24 by means of magnetic attraction force. The end portion of the sensor shaft 30 and also the end portion 40 of the king pin 24 are connectable to the magnet 46 by means of the magnetic attraction force which may be directed in the axially direction of the sensor shaft 30 and the king pin 24. The magnetism of the magnet 46 may be so strong that the attraction force may be sufficient for transmitting torque between the magnet 46 and the sensor shaft 30 and between the magnet 46 and the king pin 24. The magnet 46 may be provided with conically shaped points 50, which may interact with conically shaped indentations 52 in the end portion of the sensor shaft 30 and the king pin 24. However, the magnet 46 may be provided with conically shaped indentations 52, which may interact with conically shaped points 50 arranged in the end portion of the sensor shaft 30 and in the end portion 40 of the king pin 24. The conically shaped point 50 and indentation may have a direction so that the magnet 46 may be centred in relation to a longitudinal central axis of the king pin 24 and the sensor shaft 30.

The angle sensor 28 may be connected to the electronic control arrangement 22 comprising a measurement unit, which enabling angle measurements.

The steering arrangement 2 enables the measurement of the steering angle at a top of the king pin 24 regardless type of brake system used, i.e. disc or drum brake 44. It also facilitates mounting the angle sensor 28 since there may be no need for using distance elements, such as shims, to achieve correct pre-tension of the bearings 27 arranged between the king pin 24 and the steering knuckle 26. This reduces mounting time and costs. Also, such steering arrangement 2 enables enough space for the angle sensor 28 at the king pin 24 and the steering knuckle 26. By means of the steering arrangement 2, steering system compliance and steering angles are easily measurable on vehicles 1 equipped with either disc or drum brakes 44. Flexibility and compliance issues can easily be detected and quantified by means of the steering arrangement 2.
