DE20023449U1 - Automatic gear selector handle for vehicle, with button to move tie rod acting via connecting part against pivot joint - Google Patents

Abstract

The handle has a button (4) which can move horizontally in a casing (11) and transmit motion to the tie rod (6) by means of a traction lever turning about a cylindrical pin. A diverting lever (1) is connected to the traction rod by another cylindrical pin (3). The diverting lever is supported on the casing, and its movement is limited by a spacer (12).

Description

The innovation concerns a selector handle with push mechanism for actuation one in the selector lever arranged rod according to the preamble of the first claim.

The innovation is applicable for selector handles from Automatic circuits of motor vehicles where it is required is to redirect the movement of a button on the selector handle and by means of a transmission element, preferably a tension rod to transmit to the transmission.

In motor vehicles with an automatic shift is usually a switching or Selector handle arranged the console of the motor vehicle with which the desired gear is set. To the dialing process is to be made in the selector handle arranged a button that the driver, with his fingers, in the automatic selector handle pushes, which causes that of can be shifted from one gear to the other. In the dial there is a pull rod for this, which moves the button on the Automatic transmission transmits. at a button protruding horizontally into the automatic selector handle, the movement must the key, however, is transferred to the transmission mechanism arranged vertically in the selector handle, or redirected. Sloping surfaces on the End of the button or the pull rod. Intermediate mechanisms are also common, which based on inclined planes the force from the button up deflect the tension rod by 90 °, or transferred. This has the disadvantage that wear parts are present are that need to be replaced or serviced, require specific installation spaces and not without in every dialing position damage the drawbar can be dismantled.

Out DE 44 34 135 A1 a shift lever for a motor vehicle transmission is known, in which the shift handle is attached to the shift lever rod and is held with locking tongues. A push button moves a lever mechanism, the end of which protrudes up and down in a locking rod. This mechanism cannot be used in any selection handles specified by the car manufacturer. Its assembly is complicated and so is the disassembly.

It is therefore the task of innovation to provide a device, the disadvantages of the prior art is eliminated and can be used in various types of selection handles, whereby disassembly in any dial position without damaging the Drawbar and with little effort, with low friction and low wear may be possible should.

This task is done by an automatic selector handle on the gear lever of a motor vehicle with the characteristic features of the first claim solved.

Subclaims give advantageous refinements the innovation again.

The solution according to the innovation sees an automatic selection handle on the gear lever of a motor vehicle, which is from the selector lever to switch to the selected one Switch positions exist, a handle of the selector lever and one on the handle located button for operating a transmission element to the automatic transmission, being a pull lever opposite the housing the handle is fixed, transfers the force from the button to the tension rod. The power transmission takes place in such a way that the Pushbutton on the selector handle to move the drawbar over a driver against the extension a support lever acts, which is supported with its other end in the housing and is connected by means of a cylindrical pin to an angle lever which is in turn pivoted about a cylindrical pin on the housing and with its pen-shaped renewal protrudes into a recess of the pull rod and moves it.

It is advantageous that the push button is guided by means of a T-profile in part of the housing of the selector handle.

It is also advantageous if the support lever spherical at its lower end accomplished is.

Advantageously, the Path of the support lever bounded towards the drawbar by a spacer his.

The following is the innovation five figures and an embodiment explained in more detail.

The figures show:

1 : Automatic selector handle with deflection mechanism in with its functional parts.

2 : Automatic selector handle with deflection mechanism in one cut across the handle

3 : Representation with the functional parts of the automatic selector lever

4 : Section A – A of 3

5 : Cut across the selector handle with pull rod and housing.

The 1 shows the automatic selection handle of a motor vehicle with his button 4 against a profile 13 acts. The support lever 1 , which is with its lower end on the housing 11 is supported by means of a cylindrical pin 3 with the angle lever 2 connected, which in turn with the cylinder pin 7 on the housing 11 is pivotally arranged and with its pin-shaped extension 14 into a recess 10 the tie rod 6 protrudes ( 5 .) The extension 15 of the support lever 1 is about the carrier 8th of the T-profile 13 when pressing the pushbutton 4 entrained so that by the pivotally arranged angle lever 2 on the housing 11 the extension 14 moved up and the tie rod 6 is raised.

The 2 , a cut across the selector handle, is the interaction of lateral extension 15 of the support lever 1 and the driver 8th of the T-profile 13 refer to. Like the win kelhebel 2 with the support lever 1 through the cylinder pin 3 is connected and both levers 1 . 2 interact with each other, the angle lever 2 with the cylinder pin 7 on the housing 11 is attached, the 3 be removed. The interaction becomes clear from the lateral extension 15 of the support lever 1 also from the 4 who have a cut of 3 represents.

The 5 shows how the pen-shaped extension 14 into the recess 10 the tie rod 6 engages so that the movement of the push button 4 on the drawbar 6 is transmitted. Because the movement of the push button 4 not directly on the joint of the cylinder pin 3 , but to a much higher point, has the advantage that the transmission of the movement of the push button takes place in such a way that only 30% of the movement of the push button 4 on the drawbar 6 is transmitted. This is a major advantage of the innovation over all other known solutions.
