Description
Technical field
The utility model relates to automobile gearbox control members, and in particular to a kind of control block installed on gear lever.
Background technique
Automobile gearbox control member includes gear lever, and gear selecting shifting block and control block are installed on gear lever, and gear selecting shifting block is used
In stirring for gear selection position, control of the control block for the reverse gear switch of reverse gear indicator light.The control block of the prior art, general
Gear control is carried out in one direction, and control precision is not also high, and can not achieve self-locking function.
Summary of the invention
In view of currently known technology there are the problem of, the purpose of this utility model is intended to provide a kind of achievable reverse gear and opens
The multi-faceted high-precision control closed, and realize the self-locking control block of the high-precision curved of self-locking function.
The utility model adopts the following technical scheme that complete:
The self-locking control block of high-precision curved, using solid forging structure, it is characterised in that: by intermediate sleeve and be connected to
Between sleeve the upper fan-shaped boss of periphery, lower fan-shaped boss composition, intermediate sleeve are equipped with central shaft hole, upper sector boss up and down
Scalloped surface cam curved surface is set in the axial direction, cam curved surface includes the first surface being sequentially connected, the second curved surface,
The center line of three curved surfaces and the 4th curved surface, first surface and central shaft hole is in reversed 10 degree of angles, the second, the 4th curved surface and center
The center line of axis hole is in positive 10 degree angles, and for the center line of third curved surface and central shaft hole in 60 degree of angles of forward direction, lower sector is convex
The scalloped surface of platform is equipped with left and right triangular groove along the vertical centerline bilateral symmetry of cylindrical central sleeve, the inside arm of angle of triangular groove and perpendicular
Straight center line is in 30 degree of angles, and the outside arm of angle and vertical centerline are in 80 degree of angles, and left and right triangular groove passes through the transition of arc groove phase
Connection.
Angle of circumference of the upper and lower sector boss on intermediate sleeve is 60 degree.
The control block of above-mentioned technical proposal is provided with upper fan-shaped boss and lower sector in the periphery up and down of intermediate sleeve
Boss completes axis when the cam curved surface of the scalloped surface setting axial direction of upper sector boss is to realize that control block moves axially
It is controlled to the gear in direction, symmetrical left and right triangular groove, arc groove is arranged to realize control in the scalloped surface of lower sector boss
Clamp dog completes the gear control of circumferential direction when circumferentially rotating, and then come the multi-faceted high-precision control of realizing reverse gear switch.
In addition, angle of circumference of the upper and lower sector boss on intermediate sleeve is 60 degree, sector boss above and below is convex when more than 60 degree
The camber of wheels and triangular groove do not play gear control action, play self-locking function.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the shape assumption diagram one of the utility model,
Fig. 2 is the shape assumption diagram two of the utility model,
Fig. 3 is the front side direction view of Fig. 1,
Fig. 4 is the A-A view of Fig. 3.
Specific embodiment
As shown, the self-locking control block of the high-precision curved of the utility model, using solid forging structure, by intermediate sleeve
1 is equipped with center with the upper fan-shaped boss 2 for being connected between about 1 periphery of sleeve, the lower fan-shaped composition of boss 3, intermediate sleeve 1
Axis hole 4, angle of circumference of the upper and lower sector boss on intermediate sleeve 1 is 60 degree, and the scalloped surface of upper sector boss 2 is in axial direction
Side sets up cam curved surface 5, and cam curved surface 5 includes first surface 51, the second curved surface 52,53 and of third curved surface being sequentially connected
The center line B of 4th curved surface 54, first surface 51 and central shaft hole 4 is in reversed 10 degree of angles, the second curved surface 52, the 4th curved surface 54
It is pressed from both sides in positive 10 degree of angles, third curved surface 53 and the center line B of central shaft hole 4 in positive 60 degree with the center line B of central shaft hole 4
The scalloped surface at angle, lower sector boss 3 is equipped with left and right triangular groove 6, triangle along the vertical centerline A bilateral symmetry of cylindrical central sleeve 1
The inside arm of angle and vertical centerline A of slot 6 are in 30 degree of angles, and the outside arm of angle and vertical centerline A are in 80 degree of angles, left and right triangle
Slot 6 is connected by 7 phase transition of arc groove.
