Abstract
Abstract In a gearshift device, especially in a motor vehicle, for shifting the speeds of a transmission, with a bearing bracket with a ball joint cup that receives a ball joint sphere mounted on a gearshift lever pivotable in two planes, stops mounted on the gearshift lever and fixed stops in the area of the ball joint sphere are provided, an imaginary line connecting which runs through the central area of the ball joint sphere, one pair of stops being provided with a rounded element for rolling on the other pair of stops. An adjusting plate formed on the bearing bracket is pivotably mounted in the fastening area with a base plate, in one pivot plane (preselection plane) of the gearshift lever.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
A gearshift device in a motor vehicle for shifting the speeds of a transmission comprising: (a) a gearshift lever pivotable in two planes and mounted on a ball joint sphere; (b) said gearshift lever having two movable stops; (c) a bearing bracket cup for receiving at least a portion of said ball joint sphere; (d) two pair of fixed stops each pair fixed with respect to said cup and cooperating with said movable stops to limit the pivot angle of said lever in one of said planes; (e) said movable stops provided with an element for rolling on the fixed stops; and (f) said movable stops being colinear with a line passing through the center of said sphere and each of said pair of fixed stops being colinear with said line when engaged with said movable stops.
Claim 2
Dependent Claim
137 words
A gearshift device in a motor vehicle for shifting the speeds of a transmission comprising: (a) a gearshift lever pivotable in two planes and mounted on a ball joint sphere; (b) said gearshift lever having two movable stops; (c) a bearing bracket cup for receiving at least a portion of said ball joint sphere; (d) two pair of fixed stops each pair fixed with respect to said cup and cooperating with said movable stops to limit the pivot angle of said lever in one of said planes; (e) said movable stops provided with an element for rolling on the fixed stops; and (f) said movable stops being colinear with a line passing through the center of said sphere and each of said pair of fixed stops being colinear with said line when engaged with said movable stops.
Claim 3
Dependent Claim
46 words
A gearshift device as claimed in claim 1, wherein the stops on the gearshift lever (48, 50) include a shackle stop surrounding the ball joint sphere at a distance through an angle of approximately 180°, the ends of said shackle stop being provided with rounded elements.
Claim 4
Dependent Claim
23 words
A gearshift device as claimed in claim 2, wherein the shackle stop is molded onto a shell-like attachment on the ball joint sphere.
Claim 5
Dependent Claim
44 words
A gearshift device according to claim 1 further comprising a bearing bracket for supporting said ball joint cup, an adjusting plate for adjusting the position of said cup, said fixed stops including elastic cushion plates mounted on said adjusting plate of the bearing bracket.
Claim 6
Dependent Claim
27 words
A gearshift device as claimed in claim 4, wherein said adjusting plate of the bearing bracket is pivotably mounted in one pivot plane of the gearshift lever.
Claim 7
Dependent Claim
79 words
The gearshift device according to claim 5 further comprising a base member for holding said bearing bracket, said adjusting plate being adjustably secured to said base member and having a curved section whose radius of curvature is coextensive with that of said ball joint sphere when located within said cup and said adjusting permitting adjustment of the pivot angle relative to said base plate established by the fixed stops by means of displacement about the control axis of curvature.
