Definitions

  • the present invention relates to tools for vehicles (such as cars, buses, trucks, etc.). More specifically the present invention relates to an improved dismounting tool for use in vehicle repairs and maintenance or vehicle dismantling.
  • An object of the present invention is therefore to alleviate the abovementioned problems and provide an abutment body and an improved dismounting tool, wherein the abutment body is configured so that it may be used in a dismounting tool and the improved dismounting tool is configured to remove hubs or flanges associated with suspension and transmission assemblies having different bolt configurations.
  • the assemblies having different bolt configurations is to be understood as meaning that the improved dismounting tool can be used to remove components and/or assemblies that have various hole profiles.
  • the hole profiles refer to the relative placement of the through-holes of an assembly or component which are arranged to connect the assembly or component with another component of a vehicle.
  • an abutment body for attachment to a tool yoke of a dismounting tool for use in pulling, pushing or separating components associated with drive shafts and/or wheel shafts
  • the abutment body comprising: a main portion extending along a first axis, the main portion having a first end and a second end, and a pair of threaded securing holes arranged adjacent to the first end, wherein the pair of threaded securing holes are configured to receive a pair of securing bolts for securing the abutment body to the tool yoke; and two connecting portions extending from the second end of the main portion, each connecting portion having an elongated opening extending along a common curved path in a geometric plane perpendicular to the first axis, wherein each one of the elongated openings is configured to receive a connecting bolt for connecting the abutment body to the component that is to be separated.
  • any reference to one element of the invention being perpendicular to another element means that the first element is substantially perpendicular to the second element. For example, a deviation of a few degrees from a right angle is considered perpendicular in the case of the direction in which the connecting portions extend.
  • the first end is to be understood as being the end that is closest to the tool yoke when the abutment body is secured thereto.
  • the second end is to be understood as being the end that is closest to the component that is to be separated when the abutment body is connected thereto.
  • abutment body comprise a main body and two connecting bodies extending from one end of the main body, a T-shaped abutment body is achieved.
  • a pair of the abovementioned abutment bodies can for example be used together with a tool yoke in a dismounting tool to remove a vehicle's wheel hub.
  • the abutment bodies are connected to either side of the tool yoke and secured at a distance from each other so to align with the wheel hub bolts of the wheel hub that is to be removed.
  • the abutment bodies are then connected to the wheel hub so that a force can be applied such that the wheel hub is pulled off its shaft.
  • the force can for example be applied to the abutment bodies via the tool yoke using a hydraulic cylinder.
  • An example of such a hydraulic cylinder is disclosed in the currently unpublished and pending European Patent Application No. 15189415.1 , by the same Applicant, incorporated herein by reference.
  • the abutment body By having a pair of threaded securing holes, the abutment body can be secured to a tool yoke by means of two securing bolts, thus providing a more secure and stable connection therebetween.
  • Having two securing bolts increases both the strength of the connection in a direction parallel with the first axis, as well as the connection's capacity to prevent the abutment body from turning about the first axis. The stronger connection achieved is beneficial if the abutment body is to be used in a pulling operation.
  • a reinforcement is provided that strengthens the connecting portions so that they are less likely to deform when the abutment body is used as part of a dismounting tool.
  • a more durable abutment body is achieved.
  • the elongated opening has a width that is greater than the diameter of the connecting bolt, but smaller than the diameter of the head of the connecting bolt.
  • a connecting bolt may move freely along the length of the elongated opening and a user may therefore connect the abutment body to wheel hubs having a number of different bolt configurations.
  • a universal wheel hub dismounting tool may be achieved by using the abovementioned abutment body.
  • a more space efficient abutment body is achieved. Having an elongated opening that extends along a straight path would require more space than having the elongated opening extend along a curved path, provided that the abutment body is to be used in a wheel hub dismounting tool arranged to dismount wheel hubs of varying diameters and bolt configurations.
  • the abutment body when used in a wheel hub dismounting tool, provides a more space efficient solution to the problem of dismounting wheel hubs of a vehicle.
  • the connecting portions may be curved, in order to achieve a more space efficient abutment body. Having connecting portions that extend along a straight path would require more space than having connecting portions extending along a curved path, provided that the abutment body is to be used in a wheel hub dismounting tool arranged to dismount wheel hubs of varying diameters and bolt configurations. Thus, the abutment body, when used in a wheel hub dismounting tool, provides a more space efficient solution to the problem of dismounting wheel hubs of a vehicle.
  • the main portion may be provided with a central recess coaxially aligned with the first axis, the central recess extending in a direction from the second end towards the first end.
  • This recess is to be understood as extending into the abutment body starting from the surface of the abutment body which is arranged to face and come into contact with the wheel hub that is to be dismounted.
  • the recess can for example extent about 25 % - 50 % of the length of the main portion of the abutment body.
  • the abutment body This enables the abutment body to accommodate a bolt head located on the wheel hub that is to be dismounted, thus improving the usability of the abutment body. Having this recess also provides an improved balance between mass and strength of the abutment body.
  • the main portion As the main portion is arranged to be subjected to forces coaxially aligned with the first axis of the abutment body, the main portion of the abutment body can be provided with a recess as described above without lower the strength of the abutment body to such an extent that the structural integrity of the abutment body is compromised.
  • the pair of threaded securing holes may extend in a direction substantially parallel with the first axis. In doing so, a stronger and more durable abutment body is achieved.
  • the majority of the force experienced by the abutment body is substantially parallel with the first axis.
  • the securing holes being parallel with the first axis allows for an orientation of the securing bolts which provides a stronger connection of the abutment body to the tool yoke than what would have been possible if the securing holes had been perpendicular to the first axis.
  • the central axes of the pair of threaded securing holes may be laterally offset or otherwise not coaxially aligned.
  • the central axes of the threaded securing holes may be parallel with each other and aligned with a plane that bisects the main portion and which extends between the connecting portions of the abutment body.
  • the plane which the threaded securing holes are aligned with is substantially perpendicular to the direction in which the connecting portions extend from the main portion of the abutment body.
  • the abutment body being provided with laterally offset threaded securing holes provides a more secure connection of the abutment body to the tool yoke.
  • the securing holes be laterally offset, the securing bolts arranged to be fitted therein have a larger capacity to take up any force couple, or bending or twisting moment acting on the abutment body.
  • the main portion is at least 75 mm, measured in a direction from the first end to the second end.
  • the main portion may be at least 75 mm, preferably at least 85 mm and most preferably at least 90 mm.
  • the abutment body By having a main portion that extends at least 75 mm, the abutment body can be effectively used in wheel hub dismounting tools in such a way that wheel hubs of varying bolt configurations can be dismounted.
  • the tool yoke can be distanced from the wheel hub sufficiently to accommodate components of the vehicle that might otherwise be in the way and prevent connection of the dismounting tool to the wheel hub.
  • the main portion of the abutment body may be provided with two recesses arranged on a respective lateral surface facing a respective one of the two connecting portions, the two recesses being provided adjacent to the second end of the main portion and being arranged to receive at least a portion of a head of a respective connecting bolt for connecting the abutment body to the wheel hub that is to be dismounted.
  • the recesses arranged on either side of the abutment body are arranged such that the range of positions in which a connecting bolt can be received by the elongated opening on the connecting portions of the abutment body is increased.
  • the recesses are such that a more usable abutment body is achieved, i.e. an abutment body which, when used in a dismounting tool, can be connected wheel hubs having a wider range of dimensions and/or different bolt configurations.
  • the abutment body may be symmetric in order to achieve a more universally applicable dismounting tool when using this abutment body. Also, the abutment body being symmetric increases its usability and the users of the dismounting tool are therefore spared of any unnecessary workloads caused by an asymmetrical and non-user friendly product design.
  • the abutment body being symmetrical is to be understood as meaning that it has a plane of symmetry that is parallel with a respective central axis of the pair of threaded securing holes, i.e. that the plane of symmetry is aligned with the first axis of the main portion and also bisects the main portion.
  • the curved path may be aligned with a portion of an elliptical path, thus achieving a more space efficient abutment body.
  • Having an elongated opening that extends along a straight path would require more space than having the elongated opening extend along a curved path, provided that the abutment body is to be used in a wheel hub dismounting tool arranged to dismount wheel hubs of varying diameters and bolt configurations.
  • Having the curved path follow a portion of an elliptical path is beneficial and space efficient.
  • the abutment body when used in a wheel hub dismounting tool, provides a more space efficient solution to the problem of dismounting wheel hubs of a vehicle.
  • an improved dismounting tool comprising a tool yoke, two abutments bodies according to any one of the preceding claims and two pairs of securing bolts for securing either one of the two abutment bodies to the tool yoke, the tool yoke having two side portions and a central threaded through hole, wherein each one of the two side portions comprises a securing slit arranged to receive a pair of securing bolts for securing the abutment body to the tool yoke, each one of the securing slits extending in a direction parallel with a longitudinal axis of the tool yoke.
  • a tool yoke is in the present context to be interpreted as a part that secures two or more components so that they move together.
  • the tool yoke will however be further exemplified and described in the detailed description.
  • the slits are to be interpreted as elongated openings of a generally rectangular shape (which may or may not have rounded corners).
  • the hole openings of the slits are arranged on the same two sides of the tool yoke as those of the central through hole, so that the hole axis of each slit and the hole axis of the central through hole are parallel.
  • the present invention is based on the realization that currently available tools used for dismounting wheel hubs are often difficult to operate and/or not particularly versatile which increases costs for conventional workshops.
  • an improved dismounting tool having two abutment bodies and a tool yoke that are configured such that the dismounting tool can be used with a large variety of different wheel hubs and is furthermore robust and simple to handle, many of the problems associated with currently known products can be overcome.
  • the abutment bodies can be secured to the tool yoke in a number of different positions corresponding to wheel hubs having a number of different bolt configurations.
  • the abutment bodies are preferably secured close to the central threaded through hole of the tool yoke, and for large wheel hubs, the abutment bodies are preferably secured further apart.
  • the distance between the elongated openings of the connecting portions of the abutment bodies can be controlled by securing the abutment bodies at varying positions in the securing slits of the tool yoke.
  • the central threaded through hole of the tool yoke is to be understood as being configured to receive a tool for applying an axial force to a shaft of a vehicle and an oppositely directed force to the tool yoke.
  • the improved dismounting tool further comprises two washers, wherein each one of the two washers is arranged to connect one of the two pairs of securing bolts.
  • the dismounting tool e.g. engaging a correspondingly threaded hydraulic cylinder in the central through hole
  • a single washer having two openings i.e. one washer for each pair of securing bolts
  • the abutment bodies can be made more compact, and the overall dismounting tool is easier to assemble.
  • the circular path may be coaxially aligned with the central threaded through hole.
  • an axially directed force used to remove or dismount a wheel hub is evenly distributed among the two abutment bodies.
  • the risk of the dismounting tool failing and causing irreparable damage to either the vehicle, the dismounting tool, or the operator is diminished.
  • a safe and reliable dismounting tool is achieved.
  • Each one of the two securing slits may be configured so that each one of the two pairs of securing bolts prevents a respective one of the two abutment bodies from rotating about the first axis when the abutment body is secured to the tool yoke by means of the securing bolts.
  • the securing slits being arranged so that the abutment bodies are prevented from rotating is to be understood as meaning that the securing slits have a width that is greater than the diameter of the securing bolts, but smaller than the diameter of the head of the securing bolts.
  • Each one of the securing slits may be circumferentially defined by a respective side portion of the tool yoke, i.e. each slit may be enclosed within a respective side portion of the tool yoke.
  • the securing slits are not open, but closed slits.
  • the present inventors realize that by arranging a threaded central through hole and two slits on each side of the central through hole, the slits being enclosed within the side portions of the tool yoke, the dismounting tool is made more user friendly and most of all safe-to-use since the risk of having the tool yoke deform such that the abutment bodies slide outwards and ultimately detach from the tool yoke is diminished.
  • the tool yoke may further comprise two threaded lateral securing holes arranged on a lateral surface of the tool yoke, the threaded lateral securing holes having a central axis parallel with the longitudinal axis of the tool yoke, and wherein each one of the threaded lateral securing holes is arranged to receive a correspondingly threaded securing fastener having a bottom surface configured to abut against the pair of securing bolts within the securing slit, in order to prevent the two abutment bodies from moving away from each other during operation of the improved dismounting tool.
  • the tool yoke may also comprise two correspondingly threaded securing fasteners.
  • having the lateral securing holes allows the dismounting tool to have a larger operating range (i.e. the abutment bodies can move across larger distances since the securing fastener does not press against or abut the head of the bolt used to secure the abutment bodies to the tool yoke) and reduces the risk of an operator being clamped between the lateral securing fasteners and the securing bolts.
  • This also provides a benefit over EP2163347 , in which the components connected to the tool yoke may slide outwards and cause harm to an operator or equipment.
  • the improved dismounting tool to be discussed and presented in the following is preferably made from a rigid material such as any metal or alloys. It can, however, be made from other materials depending on the desired application as will be obvious for one skilled in the art.
  • the method for manufacturing such an improved dismounting tool using a metallic material is considered to be well known in the art and for the sake of brevity omitted in the following.
  • Fig. 1A and Fig. 1 B illustrate different perspective views of a tool yoke 2 according to an embodiment of the present invention.
