Abstract
A gear shift operation device of speed variator of mini car consists of handle set in shift lever with dust proof cover, ball surface protective cover, lining, ball surface protective cover board, conical spring, reinforced board, seat board, lower protective cover. The shift lever can rotate and axial move. Said invention combines shift selection and shifting mechanism to simplify structure and improve operation facility and reliability.
Description
Technical field:
The present invention relates to a kind of improvement of mid-get car shifting of transmission steering unit.
Background technology:
General mid-get car change-speed box all is to finish gear selecting and gear shift work with two cover mechanisms, at first carry out gear selecting: shifter bar promotes rocking arm and rotates; rocking arm drives the gear selecting backward stick action; the gear selecting pull bar drives change-speed box shift selecting rocking arm gear selecting again; after gear selecting finishes, promote shifter bar again and carry out gear shift, and shifter bar drives rocking arm and rotates; rocking arm drives the gear shift backward stick action, and the gear shift pull bar drives the shifting of transmission rocking arm again and finishes gear shift work.In order to prevent misoperation, gear selecting mechanism and gearshift are can interlocking.Because this selector gear finished by gear selecting and gear shift two cover systems, part is many, the activity link is many, uses wearing and tearing to make each junction gap increase for a long time, the reduction yarage, sometimes even malfunctioning.
Summary of the invention:
Technical matters to be solved by this invention provides a kind of two cover mechanisms with gear selecting, gear shift and is combined into a cover mechanism, and simplified structure improves yarage and reliability.
Technical scheme of the present invention is: handle is installed on the shifter bar, outside at shifter bar is equipped with dust boot, the sphere sheath, lining, sphere sheath cover plate, cone-shaped spring, brace panel, seat board, lower jacket, shifter bar can be swung needed angle by any direction in the sphere sheath, dust boot and sphere sheath cover plate bolt, pad and nut are installed on the seat board, the gear shift arm axle can rotate again and can move axially, peace is passed through hangers, control operating rod links to each other with shifter bar, handle is housed on the shifter bar, gear shift arm axle and hangers are to be rigidly connected, can be with welding, riveted joint or the body that is rigidly connected that is threaded, can also be an integral body that processes with a material, shift fork is installed on the shift shaft, shift fork can be finished the gear selecting action and finish the gear shift action around its rotation along with the gear shift arm axle moves axially, control operating rod is by lining, steel pipe, draw the ear body that is rigidly connected that is welded, also can or be threaded with riveted joint, can also be an integral body that is processed into a material.
The present invention has cancelled mutual interlocking gear because gear shift and gear selecting are made into to be finished by system of an axle with the work that two axles, two systems finish, and simplifies the structure greatly, and cost-cutting improves yarage, and the minimizing fault has improved service life.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B portion view of Fig. 1;
Fig. 4 is gear shift arm axle and shift fork structural representation;
Fig. 5 is the control operating rod structural representation.
The specific embodiment:
With reference to accompanying drawing, handle 1 is installed in shifter bar 2, in the outside of shifter bar dust boot 3 is installed, sphere sheath 4, lining 5, sphere sheath cover plate 6, cone-shaped spring 7, brace panel 8, seat board 9, lower jacket 10, shifter bar can be swung needed angle by any direction in the sphere sheath, dust boot 3 and sphere sheath cover plate 6 are used bolt, pad and nut are installed on the seat board 9, gear shift arm axle 27 can rotate again and can move axially, it is by hangers 28, control operating rod 15 links to each other with shifter bar, handle is housed on the shifter bar, gear shift arm axle and hangers are to be rigidly connected, can be with welding, riveted joint or the body that is rigidly connected that is threaded, can also be an integral body that processes with a material, shift fork 16 is installed on the shift shaft, shift fork 16 can be finished the gear selecting action and finish the gear shift action around its rotation along with gear shift arm axle 27 moves axially, control operating rod 15 is by lining 23, steel pipe 29, draw ear 26 body that is rigidly connected that is welded, also can or be threaded with riveted joint, can also be an integral body that is processed into a material.
