Description
Technical field
The utility model relates to automobile operating mechanism, is specially a kind of transmission top cover operating mechanism realizing automobile gearbox choosing, gearshift function.
Background technique
Automotive engineering develop rapidly in recent years, market is to automobile, and especially the requirement of commercial car manoeuvring performance is more and more higher.Along with commercial car adopts flexible shaft manipulation in a large number, gearbox operating mechanism becomes the important step affecting car load manoeuvring performance.
Conventional gearbox operating mechanism inefficiency, feel is unintelligible and select gear shift heavy, can not meet the need of market.
Summary of the invention
The utility model exists that feel is unintelligible, shifting is heavy and the problem of inefficiency in order to solve existing gearbox operating mechanism due to unreasonable structure, provides a kind of transmission top cover operating mechanism.
The utility model adopts following technological scheme to realize: a kind of transmission top cover operating mechanism, comprise top cover and be provided with the gear level in top cover, the gear selecting groove of left and right distribution is had in top cover below gear level, the outer end of two gear selecting grooves is all screwed with locking bolt, adjustment steel column is all placed with in gear selecting groove inside locking bolt, gear selecting spring is provided with inside two adjustment steel columns, the gear selecting pin that the inner passes gear selecting groove is placed with inside gear selecting spring, the cylinder of gear selecting pin has annular arc groove, the vertical draw-in groove arranged is had in top cover immediately below annular arc groove, goring push spring is placed with in draw-in groove, goring push spring upper end is provided with the pushing tow ball be close to annular arc groove.
When carrying out gear selecting operation, rotate shift selecting rocking arm and drive gear selecting pivoted arm and gear selecting pin to move, when gear selecting puts in place, goring push spring is under the effect of elastic force, and annular arc groove place pushing tow ball being stuck in gear selecting pin carries out spacing, and gear selecting has put in place obvious feel; When gear selecting return, the spring force of gear selecting spring is relied on to carry out revert action respectively; By regulating the length of adjustment steel column, adjusting the elastic force of gear selecting spring, and then the comfortable smooth and easy performance of adjustment gear selecting, overcoming existing gearbox operating mechanism due to unreasonable structure and having that feel is unintelligible, shifting is heavy and the problem of inefficiency.
The utility model reasonable in design is reliable, selects gear shift feel clear, and engage a gear and to pluck grade return smooth and easy, has simple, the easy to operate and advantage that cost is low of structure.
