Definitions

  • the present invention relates to a device at gear lever stands for manoeuvring a gear box for an engine vehicle according to the preamble of the appended claim 1.
  • gear lever stands for manoeuvring gear boxes for motor vehicles is equipped with a ball and socket joint with a joint ball that is applied on the gear lever for its bearing in a joint socket that is a part of the ball and socket joint which joint socket is applied in a lever console.
  • a stop is arranged, which has to be overcome with a certain action, usually pressing the gear lever in its longitudinal direction.
  • the gear lever is then axially carried in the joint ball in order to enable the longitudinal displacement movement that is required.
  • This previously known solution has proven to provide disadvantageous force relationships and demands that a large number of component are included and also brings that vibrations in the engine and the gear box are transmitted to the gear lever to a great extent.
  • the purpose with the present invention is to bring about a device at gear lever stands of the type specified above, which is composed by fewer parts, which retains the torsional movement on the gear lever and enables a more efficient reduction of vibrations in the gear lever.
  • Fig. 1 is a side view of a device at a gear lever stand according to the invention in a first gear position
  • Fig. 2 is a top view of the device with a gear lever in the same position
  • Fig. 3 is a vertical longitudinal view through the device along the line C-
  • Fig. 4 is a vertical transversal view through the device along the line B-
  • Fig. 5 is a side view through the device with the lever in an alternative gear position, for example reverse position,
  • Fig. 6 is a horizontal view through the device along the line D-D in Fig. 5, and
  • Fig. 7 is a vertical cross-section through the device along the line A-A in Fig. 6.
  • the device according to the invention is a part of a gear lever stand 1 , which outer design is disclosed in Fig. 1 and 2.
  • the gear stand 1 consists of a gear lever 2, which is pivotally mounted carried in a lever console 3, made such as a house, which is firmly mounted in a motor vehicle at the driver's place.
  • a gear lever handle 4 see dot dashed line
  • different gear positions of the lever may be occupied and thus a gear box for the propelling engine in the engine vehicle may be manoeuvred.
  • the lever movements are transmitted via a manoeuvre rod 5 to the gear box, where the different lever movements provide unique manoeuvre movements which are transmitted to the gear box in a previously known way.
  • a special reaction rod 6 protrudes from the lever stand and is arranged to be coupled to the gear box or the propelling engine of the vehicle in order to reduce vibrations and the gear lever which are transmitted via the manoeuvring rod 5 in a way previously known in itself.
  • the gear lever 2 is pivotally mounted in the gear lever console 3, i.e. the house by means of a ball and socket joint.
  • This purpose is achieved as the gear lever extends through a joint ball 7 which is a part of the ball and socket joint, which is pivotally mounted in a joint socket 8, which is carried in the lever console 3.
  • the joint ball 1 and its joint socket 8 determines the joint point or pivoting point of the gear lever 2, around which the gear shift movements of the lever takes place.
  • the manoeuvre rod 5 is coupled via a joint coupling 10, which is arranged to transfer a gear movement of the lever to the manoeuvre rod 5.
  • the gear lever extends symmetrically through the joint point in the joint ball 7, which is axially undisplaceable applied to the lever 2.
  • the joint ball 7 is made as a ring-shaped element, with a partially spherical, convex bearing surface 11 and a mainly cylindrical pervading cavity 12, which is coaxial with the gear lever 2, which by way of example is made as a tube.
  • the cavity 12 has a diameter which is larger than the diameter of the lever tube, which externally preferably is cylindrical and surrounded by one or two case-shaped coaxial damping means 13, 14, suitably in the form of rubber bushings which are threaded on the lever tube.
  • the ring-shaped joint ball 7 in equipped with a central flange 15, which is facing radially inwards and which intrudes into a corresponding ring-shaped recess at the joint between the two damping means 13, 14. These are kept in place axially by means of two metal washers 16, 17, which in turn are kept axially locked by means of pervading pins or rivets 18, 19 which extend through holes in the lever tube 20.
  • a ring-shaped distance is maintained between the damping means and the joint ball, which absorbs vibrations with small amplitudes.
  • the joint socket 8 may in principle consist of one single convex ring-shaped spherical joint surface, but is preferably divided into two ring sections, which in a known way are spring loaded towards each other in order to eliminate a play in the joint surfaces.
  • two socket parts 21 , 22 are thus arranged and carried together in a ball holder 23, which constitutes a closed tube-shaped casing 24 around the ball socket and the joint ball 7.
  • the joint socket 8 is thus arranged to keep the joint ball 7 axially fixed but also to allow pivoting movements.
  • the ball holder 23 and the lever 2 are connected in such a way that the lever may not be longitudinally displaced relative to the joint ball holder.
  • the joint ball holder 23 is instead movably suspended in the lever console 3 in order to be admitted to perform a determined and limited shift movement.
  • the joint ball holder 23 is suspended between two cylinder sector elements 25, 26 which are movably applied in the lever console or the house.
  • the suspension in these elements have in the example shown been achieved by means of an elastic ring-shaped suspension in the form of O-rings 27, 28 made of rubber, which are arranged in fitted recesses on the outside of the joint ball holder and the inside of the sector elements.
  • the damping elements are intended to absorb vibrations in the console in order to reduce vibration movements to the lever together with the damping elements 13, 14 around the lever tube 20.
  • the suspension is not intended to admit any considerable side displacement movement between the ball holder and the sector element.
  • the sector elements 25, 26 are, however, movably suspended towards the inside of the lever console 3, i.e. the house is equipped with inward facing supporting surfaces 45, 46 for the sector elements. These, and thus the joint ball holder 8, are thus vertically movable relative to the house within a predetermined moving area, which is disclosed in Fig. 4.
  • the upper end position is determined by the impact of the sector elements 25, 26 towards the downward facing wall 28 of the lever console or the house on the lower side of the upper side 47 of the house, which is equipped with an opening 48 for through-connection of the lever 2.
  • the lower end position is limited by an impact hm 30, 31 in the house, more closely in a slot 49 into which a protrusion 32 from the sector elements intrude.
  • the joint ball holder is spring loaded in a direction upwards, mainly in the longitudinal direction of the gear lever by means of a spring mechanism 33 which in the example shown consists of two draw springs 34, 35 which with an upper attachment 36 on the top are placed in a part of the house, i.e. its upper part 47. With a lower attachment 37 the draw springs 34, 35 are applied in the joint ball holder 23, more closely where the reaction rod 6 is mounted in the joint ball holder 23.
  • reaction rod 6 transmits the same vibration movement that the manoeuvring rod 5 transmits to the lower joint point 10 to the joint ball holder and thus the joint ball and the lever at its joint point 38. This is achieved by fastening the reaction rod 6 in the gear box or the engine, e.g. by means of a screw in the hole 50, and forms a rigid connection with the joint ball holder 23.
  • the vibration movements appear in phase and eliminates vibration movements on the lever in the form of oscillatory motions.
  • the gear lever displays a sidewards directed, upwards turned hooking element 40, which is firmly applied to the lower end 9 of the lever. Further, the house 3 or the console displace a downwards, rigid hooking-up part 41 arranged to cooperate with the hooking element. During normal shifting movements, the hooking element 40 is out of engagement with the hooking up part 41 and beside this due to the fact that the gear lever and its joint ball with ball holder is in its upper position, as shown in Figs. 3 and 4, due to the action of the spring mechanism.
  • the gear lever When the gear lever is about to take its special gear position, e.g. reverse position which is blocked or obstructed when the lever is in its upper position, the gear lever is pushed down by the driver who presses the gear lever body 42 with the hand, thus displacing the lever 2 axially downwards a distance along its longitudinal axis 43.
  • the joint ball 7 As the joint ball 7 is axially locked to the gear lever, the joint ball follows the axial movement downwards, where the joint socket and the ball holder 23 follow this movement and also bring the surrounding sector elements 25, 26.
  • means are arranged to create an initial movement resistance against the downwards directed movement, e.g. in the form of grinders 52 in slots.
  • the resistance is overcome, by elastic non-rigidness in the O-rings 27, 28.
  • the sector elements may slide towards the inside of the house with their outside against the action of the springs 35.
  • this movement is a pivoting movement around a pivoting point, which is determined by the mounting 50 of the reaction rod 6 in the vehicle.
  • the hooking element 40 is lowered such that it passes the hooking up part 41 when the driver also moves the gear lever and thus pivots this in the plane of the paper according to Fig. 7, where the lever is hooked up and thus retained in a hooked up position by the action of the spring mechanism that strives upwards.
  • the reverse shift is taken and retained by means of the hooking up mechanism.
