Description

A kind of five-pointed star plate

Technical field

This utility model belongs to put-put production field, is specifically related to a kind of five-pointed star plate.

Background technology

Along with the lifting of national income level, automobile becomes the preferable of people's trip and selects, and different terrain and district The people in territory, selects automobile variable speed type the most different；The automobile variable speed of main flow is divided into fluid drive and hand gear now, and at hands In dynamic speed change, the drive mechanism of automobile need one stir gearshift parts five-pointed star plate, the most different five-pointed star plate structures Directly affect automobile and stir efficiency and the stability of gearshift.

Utility model content

This utility model solves the problem in that when offer stirs gearshift in vehicle transmission mechanism, has higher stability The invisible plate of one.

Concrete technical scheme is as follows: a kind of five-pointed star plate, including disk body (1) be distributed on this disk body (1) excircle Circular arc roller shifting block (1-1), described roller shifting block (1-1) and disk body (1) integrated setting, the most adjacent described roller is dialled Block (1-1) bottom is connected, and it it is critical only that: be installed with driving lever (2) on the end face of described disk body (1), and described driving lever (2) wraps Including reinforcement bar (2-2) and be arranged on the shifting block (2-1) of reinforcement bar (2-2) outer end, the both sides of this shifting block (2-1) outer end are Circular arc, the tail end of described reinforcement bar (2-2) is fixedly connected with fixed disk (1-2), and this fixed disk (1-2) is positioned at described disk body (1) center and with this disk body (1) integrated setting；

Offering screw via (1-3) in described disk body (1) center, this screw via (1-3) sequentially passes through described Disk body (1) and fixed disk (1-2) are arranged；Being provided with round heavy stand (1-4) on the other end of described disk body (1), this is round heavy Platform (1-4) overlaps with the centrage of described screw via (1-3), and described round heavy stand (1-4) is provided with blind hole (1-41).

The principle of this technical scheme: by screw through screw via, this utility model is fastened on selector shaft；Heavy stand Internal diameter match with the axle journal cylindrical of selector shaft, make this utility model realize the location of radial direction at the axle journal of selector shaft； The bearing pin arranged on selector shaft axle journal end face is inserted blind hole, it is achieved this utility model is fixed on selector shaft axle journal, thus will The rotating torque of selector shaft passes to this utility model, makes five-pointed star plate rotate；In drive mechanism, when five-pointed star plate rotates, Elastic roller is lifted by roller shifting block, makes elastic roller cross the top of roller, slips between two roller shifting blocks the most again, thus Gear is made to be positioned at a relatively fixed position.

For preferably realizing this utility model, may further be: described shifting block (2-1) and described roller shifting block (1-1) One is correspondingly arranged, and described shifting block (2-1) is installed in that described roller shifting block (1-1) is upper and roller shifting block (1-1) is integrated sets with this Put, when this utility model rotates, driving lever stir the gear in drive mechanism, thus realize the gear shift function of drive mechanism, So, the cooperation of shifting block and roller shifting block makes gearshift in hgher efficiency；

Six described roller shifting blocks (1-1), described roller shifting block (1-1) side it is installed with on described disk body (1) excircle The radius of limit circular arc is 50mm, and the top arc radius of described roller shifting block (1-1) is 1.5mm, described roller shifting block (1-1) Another side arc radius is 15mm, and the most adjacent arc radius between described roller shifting block (1-1) bottom is 5mm, this Sample, when starting gear shift, is lifted elastic roller by the side circular arc that roller shifting block radius is 50mm, and this arc surface is shallower, Make elastic roller lifting more steadily be easier to, after elastic roller crosses the circular arc that roller shifting block top radius is 1.5mm, slip into Another side radius of roller shifting block is 15mm circular arc, due to the design that another side arc size is less, makes another side Circular arc is relatively steep, stops after elastic roller continues to slip into the circular arc that radius between two roller slider bottoms is 5mm, and elastic roller is not Easily return sliding, make roller shifting block by more reliable and more stable for the function of roller location in gearshift；

The circular arc radius of described shifting block (2-1) both sides is 3mm.

The beneficial effects of the utility model are: the round heavy stand of design and blind hole make this utility model can be stable with gearshift Axle rotates, and structure has simple easily processing；The driving lever of design is made up of reinforcement bar and shifting block, firm in structure is hardly damaged, it is ensured that The durability of work；The roller shifting block design of unique side, the function making roller shifting block be positioned by roller is more reliable and more stable.
