The invention relates to a brake transmitter arrangement for a braking system of a vehicle with the features of the preamble of claim 1, a link arrangement with a link and with the brake transmitter arrangement and a vehicle with the link arrangement.

Braking systems of small and/or very small vehicles often include brake transmitters with manually operable brake levers, which are arranged on a handlebar of the small and/or very small vehicle. An actuating force can be generated by means of the brake transmitter and introduced into a brake receiver of the brake system in order to brake a wheel of the vehicle. In mechanical brake systems, the actuating force is usually transmitted from the brake master to the brake slave by a cable.

The pamphlet DE 20 2018 004 603 U1 describes, for example, an arrangement of a frame for a vehicle, a bicycle handlebar, a bicycle fork and a braking device. The braking device includes a brake lever which is arranged on the bicycle handlebar and which has a brake cable.

It is the object of the present invention to provide a functionally improved brake transmitter for a brake system of a vehicle. This object is achieved by a brake transmitter arrangement for a braking system of a vehicle with the features of claim 1, by a link arrangement with the brake transmitter arrangement and with a link for a vehicle with the features of claim 8 and by a vehicle with the link arrangement according to claim 10. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and the attached figures.

The subject matter of the invention is a brake transmitter arrangement for a braking system of a vehicle. The vehicle has at least one wheel. For example, the vehicle is designed as a single-lane or multi-lane vehicle. The vehicle can preferably be driven by muscle power and/or electrically. In particular, the vehicle is embodied as a small and/or extremely small vehicle, meaning vehicles without a seat or self-balancing vehicles with or without a seat.

The vehicle is preferably designed as a small or very small electric vehicle or as an electric vehicle. With only one wheel, the vehicle can be designed as an electric unicycle, e.g. as a so-called monowheel or solowheel. With two or more wheels, the vehicle is preferably a scooter, in particular an electric motorcycle, an electric scooter, an electric scooter, electric kick scooter, electric scooter, e.g. e-scooter, a Segway, hoverboard, kickboard, skateboard, longboard or the like. educated. Alternatively, the vehicle can be designed as a bicycle, in particular as an electric bicycle, e.g. as a pedelec or as an e-bike. Alternatively, the vehicle can be designed as a multi-track bicycle, in particular with three or more wheels. For example, the vehicle can be a transport or cargo bike, in particular a motorized or electrically driven transport or cargo bike, in particular a three-wheel or four-wheel pedelec or a rickshaw, in particular with or without a roof, or a cabin scooter.

The vehicle has a link, by means of which the at least one wheel of the vehicle can be steered in one direction of travel. The link preferably has an axial longitudinal extent which runs transversely to the direction of travel of the vehicle. In particular, the link has a first and a second outer axial end, with an edge area adjoining the first outer axial end. Starting from the respective end, the edge region preferably has a length of at least 30 millimeters, preferably at least 50 mm, in particular at least 70 mm and/or at most 110 mm. It is preferred within the scope of the invention that the vehicle has a closure cap for each outer axial end of the link, by means of which the ends can be closed and/or closed.

The vehicle preferably has the braking system. In particular, the braking system is designed to brake the at least one wheel of the vehicle. The brake system preferably includes the brake transmitter arrangement and a brake receiver, for example a brake shoe or brake disc, to form a frictional connection with a wheel-side friction partner of the vehicle.

The brake master assembly includes a hand lever. The hand lever can be pivoted about a pivot axis when an actuating force is introduced. The pivot axis is defined, for example, by an axle device of the brake transmitter assembly. The actuating force can preferably be introduced into the brake system by means of the hand lever, in particular by manual actuation of the hand lever. The hand lever can preferably be pivoted about the pivot axis from a rest position into an actuated position. In the rest position, the braking system of the vehicle is preferably inactive, whereas in the actuated position of the Hand lever is active, so that at least one wheel is braked.

The brake transmitter arrangement preferably comprises a housing, with sections of the hand lever being accommodated in a receiving section of the housing. The hand lever is preferably fastened pivotably to the housing by means of the axle device. In particular, the hand lever has an axle seat and the housing has at least one hole, preferably two holes, for the axle device. In particular, the axle means is secured in the holes in the receiving portion and extends through the axle seat of the hand lever.

Optionally, the hand lever and the housing, in particular the receiving section, include corresponding and/or interacting upper stop elements, which form an upper end stop of the brake transmitter arrangement. It is also possible within the scope of the invention for the hand lever and the housing, in particular the receiving section, to have corresponding and/or interacting lower stop elements which form a lower end stop of the brake transmitter arrangement. The upper end stop preferably limits the pivoting of the hand lever from the actuated position into the rest position. In particular, the lower end stop limits the pivoting of the hand lever from the rest position to the operating position.

The housing and the hand lever, which is pivotably connected to the housing, can preferably be fastened to the handlebar. For this purpose, the brake transmitter arrangement preferably includes a fastening device, which is designed, for example, as a half-shell that can partially, for example half, encompass the handlebar. The housing preferably has a gripping section which can partially, e.g. half, grip the handlebar. The fastening device and the wrap-around section can preferably be connected and/or connected to form a fastening clamp, by means of which the brake transmitter arrangement can be arranged, in particular fastened, on the handlebar. For example, the wrap-around section and the fastening device can be connected to one another in a positive and/or non-positive manner, in particular screwed together to form the fastening clip. The fastening clip is preferably designed to be arranged in the edge area of the first outer axial end of the link and/or to fasten the brake transmitter arrangement in the edge area.

The brake transmitter arrangement has a cable pull, in particular with a first cable end and with a second cable end. The cable pull is designed to transmit the actuating force, in particular directly or indirectly, to the brake receiver. The cable pull is preferably designed to actuate the brake actuator of the vehicle's braking system. For this purpose, the cable pull is preferably operatively connected to the hand lever and to the brake receiver, in particular if the brake transmitter device is arranged on the handlebar. The cable pull is preferably arranged at least in sections, preferably completely, in a hollow space in the handlebar, with it extending axially along the longitudinal extension of the handlebar when the brake transmitter arrangement is arranged on the handlebar.

According to the invention, the brake transmitter arrangement has a transmission device. A translation of the actuating force from the hand lever to the cable pull can be adjusted by means of the translation device. Optionally, an actuation path between the hand lever and the cable pull can be set using the transmission device. In particular, the actuating force and optionally additionally the actuating travel can be changed, with the setting of the translation of the actuating force and optionally additionally the actuating travel being able to be carried out in particular before integration and/or commissioning of the brake transmitter arrangement on the vehicle.

It is advantageous that a braking performance of the vehicle, in particular of the braking system, can be improved by the possibility of an adjustable translation between the hand lever and the cable by means of the translation device. In particular, it can be set how strongly the braking system of the vehicle responds when the hand lever is actuated. In particular, it can be preset on the vehicle to what extent and/or to what proportion the actuating force applied to the hand lever is transferred to the brake actuator. In this way it can be achieved that the vehicle can also be braked safely on a roadway with a gradient. Accidents caused by excessive braking force and sudden wheel lock can also be avoided.

In a preferred embodiment of the invention, the transmission device comprises a swivel joint device. The swivel joint device can preferably be swiveled about a joint swivel axis. In particular, the joint pivot axis is in the same direction and/or parallel to the pivot axis about which the hand lever can be pivoted. The swivel joint device comprises, for example, two sheet metal parts. The sheet metal parts can be essentially triangular or circular, for example. In particular, they are rectified, congruent in a plan view from above assigns and / or at least partially connected to each other at a distance. Preferably, the swivel joint means is located in the cavity of the handlebar when the brake transmitter assembly is located on the handlebar.

A possible constructive implementation of the invention provides that the transmission device has a pull rod with a first rod end and a second rod end. Preferably, the first rod end is connected to the hand lever. For this purpose, the hand lever has, for example, a fastening area in which a suitable fastening section of the first rod end is fastened. For example, the fastening area is arranged on and/or formed by a hook device formed on the hand lever. In particular, the hook device grips the fastening section of the pull rod in a form-fitting manner, so that the pull rod is fastened to the hand lever with the first rod end. It is possible for the first rod end to be arranged in a rotationally fixed manner in the fastening area. Alternatively, the first rod end may be rotatable and/or slidable in the attachment area.

The second rod end of the drawbar is preferably attached to the swivel joint means in a first attachment position. For example, the first fastening position is formed and/or fixed by a bore in the swivel joint device, in particular in both sheet metal parts. In particular, the pull rod runs from the hand lever to the swivel joint device. Preferably an opening is provided in the link through which the drawbar can extend to the pivot means located, for example, in the cavity of the link. The second rod end can preferably be pivoted together with the pivot joint device about the joint pivot axis. It is possible here that the second rod end is arranged in a rotationally fixed manner in the first fastening position. Alternatively, the second rod end may be rotatably and/or slidably disposed in the first mounting position.

In a further possible design implementation of the invention, the first cable end of the cable pull is attached to the swivel joint device in a second attachment position. For example, the second fastening position is formed and/or fixed by a further bore in the swivel joint device, in particular in both sheet metal parts. Preferably, the first cable end can be pivoted about the joint pivot axis together with the pivot joint device. It is possible here that the first cable end is arranged in a rotationally fixed manner in the second fastening position. Alternatively, the first cable end can be arranged rotatably and/or slidably in the second attachment position. The second cable end of the cable pull is preferably connected directly or indirectly to the brake receiver, in particular with the interposition of at least one functional component of the brake system.

It is preferred within the scope of the invention that by attaching the pull rod to the hand lever during and/or during the transfer of the hand lever from the rest position to the actuated position, the pull rod is pulled, with the result that the swivel joint device is swiveled about the joint swivel axis will. By pulling on the tie rod and by pivoting the swivel joint device, the tie rod is moved in a first direction, in particular upwards. Furthermore, it is preferred within the scope of the invention that the cable pull is pulled, in particular due to the attachment of the cable pull to the swivel joint device, when this is swiveled about the joint swivel axis. The pivoting of the swivel joint device preferably triggers a pulling, directed axially along the longitudinal extent of the link, on the cable pull, which preferably extends in the hollow space of the link. In particular, the brake receiver is activated at and/or during the pulling of the cable in the axial direction when the brake master assembly forms part of the vehicle's braking system.

It is particularly preferred within the scope of the invention that the translation of the actuating force between the hand lever and the cable pull is dependent on the arrangement of the first fastening position relative to the second fastening position on the swivel joint device. The translation of the actuating force between the hand lever and the cable pull can preferably be adjusted and/or changed by the arrangement of the first fastening position in relation to the second fastening position on the swivel joint device. Because the distances between the two fastening positions and optionally additionally between the joint pivot axis and the first fastening position and/or the second fastening position are varied, the actuation paths between the hand lever or the pull rod and the pull cable are changed. This leads in particular to a correspondingly changed translation of the actuating force between the hand lever and the cable.

In one possible embodiment of the invention, the brake transmitter assembly includes at least one reset device, which is designed to reset the hand lever from the operating position to the rest position, especially when no manual force is applied to the Hand lever more done. For example, the restoring device is designed as at least one elastic device, for example as at least one tension spring. The restoring device preferably stores the manual actuating force during and/or during the transfer of the hand lever from the rest position to the actuating position. In particular, the restoring device returns the hand lever to the rest position with the stored actuating force. The restoring device is preferably fixed to the hand lever, for example to the hook device, and to the housing, for example to the wrap-around section.

In a possible structural embodiment of the invention, the transmission device has a swivel joint housing. Preferably, the swivel joint means is pivotally received in the swivel joint housing. Preferably, the pivot joint means includes a pivot pin. In particular, the swivel joint device comprises a sliding sleeve. Preferably, the pivot pin is received in the sliding sleeve. In particular, the pivot pin is mounted pivotably in the pivot joint housing via the sliding sleeve.

In a further possible constructional configuration of the invention, the swivel joint housing has a first through-opening and a second through-opening. The tie rod preferably extends through the first passage opening between the hand lever and the swivel joint device. In particular, the cable pull extends axially away from the swivel joint device through the second passage opening, in particular to the brake receiver or to the at least one functional component of the brake system.

A further object of the invention is a link arrangement with the brake transmitter arrangement designed according to the previous description and/or according to one of claims 1 to 7. The link assembly also includes a link for a vehicle. The handlebar and/or the vehicle are preferably designed according to the previous description.

The brake transmitter assembly is arranged on the handlebar. The brake transmitter arrangement is preferably fastened in the edge area of the handlebar, with the edge area adjoining the first outer axial end of the handlebar.

In a preferred embodiment of the invention, the link has a cavity and an opening leading into the cavity. The opening is preferably arranged in the edge area. Preferably, the handlebar includes a tube surrounding the cavity. Preferably the tube has the opening.

In a possible development of the invention, the swivel joint housing and/or the swivel joint device is/are arranged in the cavity, in particular completely accommodated therein. Preferably, the pull rod extends from the hand lever through the opening in the handlebar to the swivel joint means. In particular, the pull rod, optionally starting from the hand lever of the brake transmitter arrangement, is guided through the opening into the cavity and attached to the swivel joint device. In particular, the opening is arranged overlapping or congruent with the first through-opening in the swivel joint housing in a top view of the link. In particular, the tie rod extends through the opening and through the first through opening.

The second through-opening, through which the cable exits the swivel joint housing, is preferably made in the swivel joint housing in such a way that it is directed in the axial direction towards the second outer axial end of the link. The cable pull can thus extend axially in the cavity from the swivel joint device to the brake calliper or the at least one functional component of the brake system.

In a particularly preferred embodiment of the invention, the brake transmitter arrangement is fastened in the edge area of the handlebar in such a way that the hand lever, in particular an actuating section of the hand lever, extends to the second outer end of the handlebar. In particular, the actuating section of the hand lever runs in the same direction and/or parallel to the axial longitudinal extent of the handlebar, in particular transversely to the direction of travel of the vehicle, pointing towards the second outer end of the handlebar. The housing is preferably at a smaller distance from the first outer axial end than the hand lever. It is possible that the housing is arranged adjacent to the closure cap of the first outer axial end.

It is advantageous that this positioning of the brake transmitter arrangement, in particular the hand lever, allows the integration of the swivel joint device and/or the swivel joint housing into the cavity and the insertion of the connecting rod through the opening. The step-up device can thus be largely integrated and the cable pull can be fully integrated in the cavity and guided to the brake receiver or to the at least one functional component so that it is invisible from the outside. Due to the invisible integration, the vehicle can have a simple appearance, which is too optical can lead to benefits. In addition, the translation device and the cable in the cavity are well protected against damage, for example due to the vehicle tipping over and hitting a ground, so that damage to the cable and thus the brake system can be avoided in an advantageous manner.

A further advantage is that the hands of the driver of the vehicle are protected in the event of accidents or certain driving manoeuvres, since the housing is arranged in particular further out on the handlebars than the hand lever on whose actuating surface the driver's hand is arranged. If the vehicle tips over, it can thus advantageously be avoided that the hand is pinched and injured between the first outer axial end of the link and the ground. Injuries that can occur due to driving the vehicle relatively close along a wall can also be avoided. Also in this case, the hand lever directed towards the second outer axial end of the handlebar and/or the housing arranged outside at the first end can prevent the hand from being pinched between the first end and the wall.

A vehicle with the link arrangement according to the previous description and/or according to claim 8 or 9 forms a further subject of the invention. The vehicle is preferably designed according to the previous description.

Corresponding or identical parts are each provided with the same reference symbols in the figures.

In the 1 A perspective front view of a vehicle 1 is shown. The vehicle 1 is designed as an electrically driven scooter, in particular as an e-scooter. The vehicle 1 has a handlebar 2 . The vehicle 1 has a first, steerable front wheel 4 and a second, steerable rear wheel 5, which are rotatably arranged on a frame 6 of the vehicle. The handlebar 2 is connected to a wheel fork 8 of the front wheel 4 via a frame rod 7 so that it can be steered by means of the handlebar 2 . The vehicle 1 includes a braking system 9 by means of which the first wheel 4 and/or the second wheel 5 can be braked. The brake system 9 comprises a brake transmitter arrangement 10 and a brake receiver which is operatively connected to the brake transmitter arrangement 10 in order to form a frictional connection with a friction partner on the wheel.

The link 2 has an axial longitudinal extent which runs transversely to a direction of travel F of the vehicle. The link 2 has two outer axial ends 3,24. A first axial outer end 3 is adjoined by an edge region 11 . Starting from the first end 3, the edge region 11 has a length of at least 30 mm, preferably at least 50 mm, in particular at least 70 mm and/or at most 110 mm. In the edge area 11, the brake transmitter assembly 10 is attached.

the 2 shows a perspective top view of a tube 12, which forms part of the handlebar 2. The tube 12 has a cavity 13 . In the edge area 11 of the tube 12 there is an opening 14 which forms an access to the cavity 13 .

the 3 shows a longitudinal section through a link arrangement 50 which includes the link 2 and the brake transmitter arrangement 10 . Shown is a section of the handlebar 2 with the tube 12 which has the first axial outer end 3 . This is closed with a closure cap 15 which is inserted into the tube 12 . The handlebar 2 has a casing 16 which can be formed from a foam material or from rubber, for example. The casing 16 extends along the longitudinal extent of the link 2 and surrounds the tube 12, with the edge region 11 adjoining the first axial outer end 3 being recessed.

The brake transmitter arrangement 10 is fastened in the edge area 11 of the handlebar 2 . The brake transmitter assembly 10 comprises a housing 17, a hand lever 18, a fastening device 19, a cable pull 20, two resetting devices 21, only one of which is visible, and a transmission device 38.

The hand lever 18 is pivotally connected to the housing 17 via an axle device 22 of the brake transmitter arrangement 10 . As a result, when an actuating force F is introduced manually, the hand lever 18 can be transferred, in particular via an actuating surface 23 of the hand lever 18, from a rest position R shown into an actuating position not shown. In the actuated position, the brake actuator of vehicle 1 is active, so that its front wheel 4 and/or rear wheel 5 is braked.

The brake transmitter arrangement 10 is arranged on the first end 3 in such a way that the hand lever 18 , in particular the actuating surface 23 , extends essentially in the same direction and/or parallel to the longitudinal extension of the handlebar 2 . In this arrangement, the hand lever 18 points away from the first axial outer end 3 . He is to a second outer axial end 24 of the handlebar 2 (see 1 ) directed. This has the advantage that injuries to a hand of the driver of the vehicle 1 in an accident, in particular if the vehicle 1 tips over and hits a surface, are better protected against injury, since the hand is avoided between the surface and the handlebars 2 is trapped. Even when driving too close to a wall, the described arrangement of the brake transmitter arrangement 10 and alignment of the hand lever 18 can help to ensure that the hand is not pinched between the wall and the handlebar 2 .

A further advantage of the described arrangement of the brake transmitter assembly 10 and the orientation of the hand lever 18 is that the cable 20 and a large part of the transmission device 38 can be accommodated in the cavity 13 of the tube 12 . The cable pull 20 and the majority of the transmission device 38 are thus integrated in the handlebar 2 in a space-saving manner and are invisible from the outside. There they are well protected against damage that can occur, for example, as a result of an accident or as a result of the vehicle 1 tipping over.

In the 4 a perspective plan view from above of the hand lever 18, in particular of the actuating surface 23, is shown. the 5 shows a perspective top view of the hand lever 18 from below. The actuating surface 23 extends in a first longitudinal area of the hand lever 18. At the end, in a second longitudinal area of the hand lever 18, different functional devices of the hand lever 18 are arranged and/or formed.

The hand lever 18 has at the end in the second longitudinal region a hook device 25 with two opposite hook elements 26a, 26b directed in the same direction. A bore is made in each of the hook elements 26a, 26b, which forms an engagement interface 27 for the restoring devices 21. Each hook element 26a, 26b forms a lower stop element 28 of the hand lever 16 for a lower end stop 29 of the brake transmitter assembly 10 (see 3 ).

The hand lever 16 has an axle seat 30 for the axle device 22 (see 3 ) on. The axle seat 30 is formed by a bore which runs completely transversely through the second longitudinal area of the hand lever 18 .

The hand lever 18 also includes upper stop elements 31 for an upper end stop 32 (see FIG 3 ) of the brake transmitter arrangement 10. The upper stop elements 31 are designed as lugs which protrude laterally from the hand lever 18.

In the 6 and 7 different perspective views of the housing 17 are shown. The housing 17 has a receiving section 33 and an encompassing section 34 . The receiving section 33 comprises two side walls 35a, 35b and a top wall 41, which together delimit a receiving area. The receiving section 33 is intended to receive the hand lever 18 in sections in the receiving area and to arrange it pivotably on the housing 17 . For this purpose, a hole 39 is provided in each side wall 35a, 35b for the passage of the axle device 22 (see 3 ) is provided. The axle device 22 can be fixed in the two holes 39 . The axle assembly 22 extends through the axle seat 30 in the hand lever 18 (see FIG 4 and 5 ) and ends with both ends in the holes 39. As can be seen from the 3 As can be seen, the axle device 22 forms a pivot axis 67 about which the hand lever 18 can be pivoted from the rest position R into the actuated position.

In the 8th a section of the receiving section 33 is shown with a view into the receiving space enclosed within the side walls 35a, 35b and the top wall 41. Further upper stop elements 40 are formed on each side wall 35a, 35b and extend from the respective side wall 35a, 35b into the receiving space. Together with the upper stop elements 31 of the hand lever 18 (see 4 and 5 ), the further upper stop elements 40 form the upper end stop 32 of the brake transmitter arrangement 10 (see 3 ).

Two further lower stop elements 42 are arranged on the top wall 41 of the receiving section 33 and protrude into the receiving space. Together with the lower stop elements 28 of the hand lever 18 (see 4 and 5 ), the further lower stop elements 42 form the lower end stop 29 of the brake transmitter arrangement 10 (see 3 ).

The wrap-around portion 34 of the housing 17 is designed to hold the tube 12 (see FIG 2 and 3 ) partially, especially half, to encompass. For this purpose, it has an essentially curved, in particular semi-annular shape, the radius of which is essentially the same as the radius of the tube 12 .

The wrap-around section 34 has two connection interfaces 36 for connection to mating connection interfaces 37 of the fastening device 19 which is designed to fasten the brake transmitter arrangement 10 to the handlebar 2 . The fastening device 19 is in the 9 shown in a top perspective view. The fastening device 19 is designed as a half-shell. The half-shell has a radius which essentially corresponds to the radius of the tube 12 . As a result, the fastening device 19 can be placed on the pipe 12 and partially encompass it, for example halfway.

How from the 3 As can be seen, the fastening device 19 together with the gripping section 34 of the housing 17 can form a fastening clamp 54 for fastening the brake transmitter arrangement 10 to the handlebar 2 . The fastening clip 54 completely surrounds the tube 12 of the handlebar 2 in the edge area 11 . To form the fastening clip 54, the fastening device 19 is fastened, in particular screwed, to the wraparound section 34 in the connection interfaces 36 and connection counter-interfaces 37 provided for this purpose by means of fastening means, for example screws.

According to the 7 the housing 17 has two attachment interfaces 43 which are designed as bores in the wraparound section 34 . The reset devices 21 can be fastened in the fastening interfaces 43 .

Thus, the restoring devices 21 extend, as in FIG 3 evident, between the engagement interfaces 27 of the hand lever 18 (see 4 and 5 ) and the attachment interfaces 43 of the housing 17. When the hand lever 18 is actuated and the rest position R is transferred into the actuated position, the restoring devices 21, which are designed as tension springs, are tensioned. When the actuating force is no longer acting on the hand lever 18 and it is not actuated, the tension springs pull the hand lever 18 back into the rest position R.

According to the 3 the transmission device 38 has a pull rod 46, a swivel joint device 47 and a swivel joint housing 48.

The swivel joint housing 48 is in the 10 in a perspective side view and in the 11 shown in an axial rear plan view. The swivel joint housing 48 is a sheet metal part which is essentially or largely in the form of a circular cylinder. It has an axial longitudinal extent and dimensions by means of which it can be inserted into the cavity 13 of the tube 12 (see 2 and 3 ) can be recorded.

At a front axial end, which according to the 3 is directed towards the first outer axial end 3 of the link 2 , the swivel joint housing 48 has a circular bead 49 . According to the 3 the bead 49 surrounds the tube 12 at its first end 3 so that it is arranged between the tube 12 and the closure cap 15 . As a result, the swivel joint housing 48 is positively secured in the cavity 13 against axial slipping in the cavity 13 .

The pivot joint housing 48 has a first through opening 51 and a second through opening 52 . The first through opening 51 is made in a jacket 55 of the swivel joint housing 48 which extends axially. The second through hole 52 is in accordance with 11 introduced at the rear axial end of the swivel joint housing 48, which in the installation situation according to 3 faces away from the first outer axial end 3 of the link 2 .

How from the 3 As can be seen, the first through-opening 51 is arranged congruently with the opening 14 in the tube 12, so that access to an interior space 56 of the swivel joint housing 48 is formed. In the inner space 56 of the pivot joint housing 48, the pivot joint device 47 is accommodated in a pivotable manner.

the 12 shows a perspective cross section through the pivot joint housing 48 in which the pivot joint device 47 is arranged pivotable about a joint pivot axis 64 . The joint pivot axis 64 runs in the same direction and/or parallel to the pivot axis 67 about which the hand lever 18 can be pivoted. Due to the fact that the swivel joint housing 48 and the swivel joint device 47 accommodated therein are arranged in the cavity 13 of the tube 12, they are arranged invisibly, space-savingly and protected against damage.

The swivel joint device 47 comprises a first sheet metal part 57 and a second sheet metal part 58, which are essentially triangular. The sheet metal parts 57, 58 are arranged in the same direction and spaced apart from one another and are connected to one another via a pivot pin 59 of the pivot joint device 47. The pivot pin 59 is coaxial with the joint pivot axis 64 . The pivot pin 59 is accommodated in a sliding sleeve 60 of the pivot joint device 47 . The swivel joint housing 48 has a sliding sleeve receptacle 61 which is integrated into the jacket 55 in the form of a bulge. The two sheet metal parts 57, 58 can be pivoted about the joint pivot axis 64 in the sliding sleeve receptacle 61 by means of the pivot pin 59.

The tie rod 46 extends between the hand lever 18 and the swivel joint device 47, being firmly connected to the two sheet metal parts 57, 58 and the hand lever 18. For this purpose, the pull rod 46 runs through a free space 53 in the gripping section 36 of the housing 17.

The tie rod 46 can transmit the actuating force F acting on the hand lever 18 to the swivel joint device 47 . To transmit the actuating force F, the pull rod 46 is moved upwards by the hand lever 18 pivoting about the pivot axis 67 and at the same time a little axially to the first outer end 3 of the link 2, as a result of which the swivel joint device 47 is pivoted about the joint swivel axis 64.

For attachment to the hand lever 18, the pull rod 46 has a cylindrical attachment section 44 at one end of the rod, which is fitted in an attachment area 45 formed by the hook elements 26a, 26b of the hand lever 18 (see Fig 4 ) rotatably or alternatively rotatably and/or slidably seated. For attachment to the swivel joint device 47, the pull rod 46 has an engaging cylinder 63 on a second rod end. In each of the sheet metal parts 57, 58 of the swivel joint device 47, a bore 62 for the engagement cylinder 63 is introduced in a first fastening position 68. The engaging cylinder 63 is, as in the 3 shown, held in the bores 62 in a rotationally fixed or alternatively rotatable and/or slidable manner. Thus, the tie rod 46, in particular the second rod end, can be pivoted together with the pivot joint device 47 about the joint pivot axis 64.

The cable 20 is also attached to the swivel joint device 47 . For this purpose, it has a further engagement cylinder 65 on a first rope end, which is arranged in further bores 66 in the sheet metal parts 57, 58 in a rotationally fixed manner or alternatively rotatably and/or slidably. The further bores 66 define a second fastening position 69 on the swivel joint device 47. The cable pull 20, in particular the first cable end, can thus be swiveled together with the swivel joint device 47 about the joint swivel axis 64. From the further bores 66, the cable 20 extends through the second passage opening 52 in the swivel joint housing 48 axially through the cavity 13 of the tube 12, the cable 20 being connected at a second cable end to at least one further functional component of the brake system of the vehicle 1 in the cavity 13 and/or is connected to the brake calliper of the vehicle 1. Because the cable 20 is arranged in the cavity 13, it is invisible, space-saving and protected against damage.

When triggered by the actuation of the pivot lever 18 pivoting of the swivel joint device 47 about the joint pivot axis 64, the cable 20 in the installation situation according to 3 pulled a little axially towards the first outer end 3 of the handlebar 2, so that the cable pull 20 is shortened in relation to the at least one further functional component and/or the brake calliper and the functional component and/or the brake calliper is thereby activated.

A translation of the actuating force F and optionally an additional actuating travel from the hand lever 18 to the cable 20 depends on the first fastening position 68 and the second fastening position 69, their arrangement relative to one another and/or relative to the joint pivot axis 64. The translation can be adapted to this effect and /or be adjusted so that better braking performance of the vehicle 1 is achieved can be avoided and accidents caused by excessively sudden braking can be avoided.

The fastening positions 68, 69 are selected in a corresponding manner in order to adapt and/or set the translated actuating force F and optionally additionally the translated actuating travel. In particular, the fastening positions 68, 69 are defined in relation to one another and/or to the joint pivot axis 64 in order to carry out the adaptation and/or adjustment. For example, a set with a large number of pairs of sheet metal parts can be provided, so that a pair of sheet metal parts suitable for the respective selected transmission of the actuating force F can be provided in the swivel joint device 47 .
