Abstract

The invention provides an operating lever track slab with simple and reliable structure and an operating lever locating mechanism. The operating lever locating mechanism comprises an oscillating bar and a ball pin in sliding connection with the oscillating bar in the axial direction; the operating lever track slab has a structure that an elastic element enabling a ball head of the ball pin to be in contact with a track in a normal state is arranged between the oscillating bar and the ball pin. The operating lever track slab is characterized in that a track slab is provided with the track for the ball pin to move inside; the track is provided with a plurality of pits matched with the ball head of the ball pin so as to enable the ball head to be in a stable state, and the surfaces of the pits are parts of a sphere; the track changes in the length direction, the width direction and the thickness direction of the track slab, i.e. the X direction, the Y direction and the Z direction; and the bottom surface of the track arranged between two adjacent pits in the X direction protrudes upwards.

Description

Operating lever locating mechanism and operating lever track slab

Technical field

The present invention relates to the operating lever locating mechanism and the operating lever track slab of automobile gearbox.

Background technology

The effect of operating lever locating mechanism is to make joystick be stabilized on certain gear, and will have the variation of operating effort sense when gear shift.Existing operating lever locating mechanism generally comprises fork, with fork at the ball end that axially becomes sliding block joint; Have the operating lever track slab of track, make the elastic element that the bulb of ball end contacts with track when between fork and ball end, being provided with in normality.The structure of using is with X, Y direction separately, uses two groups of ramp structures (two track plates of joystick are arranged) respectively, the combination mechanism of two cover inclined-plane+springs, and realizable force sense and location, the complex structure number of parts is many, and reliability is relatively poor, and the cost height.

Summary of the invention

The purpose of this invention is to provide a kind of failure-free operating lever track slab simple for structure.

Operating lever track slab of the present invention has the track that moves for ball end within it on a track plate; Have a plurality of matching with the bulb of ball end so that bulb is in the pit of stabilized conditions on the track, the surface of pit is the part of sphere; Track promptly changes to three directions to, Z to, Y at X at the length direction of track plate, Width, thickness direction; Make progress track bottom surface between two adjacent pits to upper process at X.

The beneficial effect of this operating lever track slab: only use a track plate, promptly on a track plate, have track, simple for structure; Make progress track bottom surface between two adjacent pits to upper process at X, make to move up and when shifting gears, ball end will slide up and down on direction at Z, has tangible power sense and changes at X at joystick.

As improvement, described operating lever track slab makes progress track bottom surface between two adjacent pits to upper process at Y.Make to move up and when shifting gears, ball end will slide up and down on direction at Z at Y, have tangible power sense and change at joystick.

The operating effort sense changed tangible operating lever locating mechanism when the present invention provided a kind of reliable, gear shift simple for structure simultaneously.

Operating lever locating mechanism of the present invention, comprise fork, with fork at the ball end, the described operating lever track slab that axially become sliding block joint, make the elastic element (as spring) that the bulb of ball end contacts with track when between fork and ball end, being provided with in normality.

The beneficial effect of this operating lever locating mechanism: only use a track plate+spring structure can realize the joystick location, simple for structure reliable.Make progress track bottom surface between two adjacent pits to upper process at X, make to move up and when shifting gears, ball end will slide up and down on direction at Z, has tangible power sense and changes at X at joystick.Therefore, this operating lever locating mechanism uses one 3 dimension track structure, realizes the location and the operating effort sense of joystick, cooperates sensor again, realizes the ride control of people to vehicle.

The specific embodiment

Referring to the operating lever locating mechanism shown in Fig. 6-7, comprise one can around the fork 20 of a fixed point (centre of sphere) swing, with fork 20 at the axial ball end 21 that becomes sliding block joint, have an operating lever track slab 23 of track 22, make the spring 24 that the bulb 25 of ball end contacts with track when between fork and ball end, being provided with in normality.

Referring to the operating lever track slab 23 shown in Fig. 1-5.Having 7 on the track matches so that bulb 25 is in the

pit

31,33,34,36,38,39,42 of stabilized conditions with the bulb of ball end.Match with bulb 25 spheres in the surface of each pit.Be respectively X with length direction, Width, the thickness direction of track plate and see Fig. 1 to X, Y, the Z coordinate figure of, Z its centre of

sphere
