Abstract
The invention discloses a transmission shifting and positioning mechanism. The transmission shifting and positioning mechanism comprises a gearbox body, a shifting shaft, a gear switching table and a shifting positioning pin. The shifting shaft, the gear switching table and the shifting positioning pin are arranged in the gearbox body; the gear switching table is in a circular-truncated-cone shape and is fixed to the shifting shaft in a surrounding and sleeving mode; a gear groove is formed in the side wall of the gear switching table, and the gear positioning pin abuts against the gear groove in a stretchable mode. As the gear switching table and the shifting positioning pin are matched to lock gears, the shifting positioning pin stably reciprocates, and a gear taking-off phenomenon can be avoided; as the gear switching table is in the circular-truncated-cone shape and is arranged on the shifting shaft in the surrounding mode, the whole shifting and positioning mechanism is small in size, easy to arrange and stable in working.
Description
Technical field
The invention belongs to motor car engine speed changer field, be specifically related to a kind of shifting of transmission positioning means.
Background technique
The automobile-used double-clutch speed changer of prior art (be called for short: DCT) or automatic transmission speed changer (be called for short: gear shift AT) and halting mechanism are as shown in Figure 1.During gear shift, drive cockscomb tooth 02 to rotate primarily of shift shaft 01, cockscomb tooth 02 is arranged multiple gear groove, different slotted eye represents different gear, specifically can be divided into parking shelves, reverse gear, neutral gear and forward gears (being called for short: P shelves, R shelves, N shelves and D shelves).After shift shaft 01 rotates selected gear, corresponding gear groove rotates and snaps in notch by the gear card 04 be fixed on transmission case casing and positions, this structure cockscomb tooth 02 needs and a cockscomb tooth pull bar 03 coordinates compacting park pawl 05, cause gear box size larger, gear card 04, owing to being that chip snaps in mode, also existing and snaps in the unstable problem in location.
Summary of the invention
The present invention discloses a kind of shifting of transmission positioning means, reduces gear shift Position Design space and realizes gear shift position stability simultaneously.
A kind of shifting of transmission positioning means disclosed by the invention, comprising: gear box, shift shaft, gear switch platform, gear shift locating stud;
Shift shaft, gear switch platform, gear shift locating stud are positioned in gear box;
Described gear switch platform is round table-like, and is fixed on shift shaft around suit;
Described gear switch platform sidewall arranges gear groove, and gear shift locating stud extension type props up gear groove.
Further, the shank of gear shift locating stud is socketed a spring and is inserted in the hollow key of a gear shift holding down bolt together with spring, shank is guide movement in hollow key, and spring two props up gear shift locating stud plunger and hollow key corresponding surface respectively and drives gear locating stud extension type to prop up gear groove; Described gear shift holding down bolt bolt head is fixed on gear box sidewall.
Further, described gear switch platform is sleeved on shift shaft, and is fixed on shift shaft axis body through gear switch platform sidewall by a bolt.
Advantageous Effects of the present invention is: adopt gear switch platform and gear shift detent fit to lock gear, because the to-and-fro motion of stretching of gear shift locating stud is stablized, there will not be the problem bad and out of supply with parking stall slot fit; Further, gear switch platform presents round table-like, and around being arranged on shift shaft, whole gear shift positioning means volume is little, arranges easy, working stability.
