Abstract
The utility model relates to a novel shift actuating mechanism. The novel shift actuating mechanism comprises a shift actuating mechanism main body and shift elastic steel balls. Auxiliary grooves are formed in the left side and the right side of a primary groove in the top of the shift actuating mechanism main body respectively, the length of the auxiliary grooves is equal to that of the primary groove, and cross sections of the auxiliary grooves are matched with those of the shift elastic steel balls in shape. The novel shift actuating mechanism enables the shift elastic steel balls to be limited by the newly-arranged groove of the shift actuating mechanism main body when the shift elastic steel balls are in other gears, positions of the shift elastic steel balls in other gears are controlled, and shift comfort of a whole car is improved.
Description
Technical field
The utility model relates to a kind of gearbox shifting actuator, especially relates to a kind of elastic steel ball of shifting gears in the accurate fixing novel gearshift actuator of other gears.
Background technique
The automobile great majority that China uses at present still are hand gear, the hand gear automobile is because the operation of shift hunting, easily make driver fatigue, and different driving technology levels causes bigger difference to fuel economy, the riding comfort of vehicle, expects so the automatic speed changing automobile is people.
Shift of transmission is to rely on the gearshift elastic steel ball to realize in reeded gearshift main body motion, has only a groove on the gearshift main body at present, the gearshift elastic steel ball only is subjected to indentation limitations at neutral gear position, it only is the position when having controlled gearshift elastic steel ball neutral, do not control the position of gearshift elastic steel ball when other gears, the position of elastic steel ball when other gears that can cause like this shifting gears can't accurately be fixed, feed back on the shift handle, amount of exercise can be bigger when other gears to make the driver experience shift handle, influences the shifting comfort of car load.
Chinese patent notification number CN 201386785 Y, on January 20 2010 day for announcing, name is called shift-selecting and changing actuating mechanism, comprises block selecting device, gearshift, shifting shift fork, gearshift axle, rotary angle transmitter, and the block selecting device comprises motor, worm screw, worm gear; Gearshift comprises gas pressure source, three or six solenoid valves, cylinder body, range piston, positioning piston, end cap.Three or six solenoid valves are integrated into combination brake switch and proporting.Rotary angle transmitter is two, and a rotary angle transmitter is connected worm gear central shaft axle head; A rotary angle transmitter is connected gearshift axle axle head; The rotary angle transmitter wire harness is connected with electric control mechanical type automatic speed variator ECU.Its deficiency is that the position of gearshift elastic steel ball when other gears can't accurately be fixed, and influences the shifting comfort of car load.
The model utility content
The purpose of this utility model is can't accurately fix in order to solve the position of existing gearshift elastic steel ball when other gears, influence car load shifting comfort defective and provide a kind of elastic steel ball of shifting gears in novel gearshift actuator that other gears are accurately fixed.
To achieve these goals, the utility model is by the following technical solutions:
A kind of novel gearshift actuator comprises gearshift actuator main body, gearshift elastic steel ball, and the position of the right and left of described gearshift actuator main body top master's groove has secondary groove.In the technical program, main groove the right and left in gearshift actuator main body respectively increases a secondary groove, that is to say in gearshift actuator main body and have three grooves, when neutral gear position, be the same with existing gearshift actuator, in the groove that the gearshift elastic steel ball mediates, when other gears, the indentation limitations that the gearshift elastic steel ball is increased newly by shifting actuator main body, control the position of gearshift elastic steel ball when other gears, improved the shifting comfort of car load.
As preferably, the length of secondary groove is identical with the length of main groove.
As preferably, the shape of secondary groove cross section matches with the cross section of gearshift elastic steel ball.In the technical program, make secondary groove and gearshift elastic steel ball match, make them when other gears, the gearshift elastic steel ball can not skid off secondary groove.
The beneficial effects of the utility model are, the indentation limitations that gearshift actuator of the present utility model feasible gearshift elastic steel ball is increased newly by shifting actuator main body when other gears, control the position of gearshift elastic steel ball when other gears, improved the shifting comfort of car load.
Description of drawings
Fig. 1 is that the utility model gearshift elastic steel ball is at the schematic representation of neutral.
Fig. 2 is that the utility model gearshift elastic steel ball is at the schematic representation of other gears.
Among the figure, 1, gearshift actuator main body; 2, gearshift elastic steel ball; 3, main groove; 4, secondary groove.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further explained:
With reference to Fig. 1, a kind of novel gearshift actuator comprises gearshift actuator main body 1, gearshift elastic steel ball 2, and the position of the right and left of described gearshift actuator main body 1 top master's groove 3 has secondary groove 4.The length of secondary groove 4 is identical with the length of main groove 3.The shape of secondary groove 4 cross sections matches with the cross section of gearshift elastic steel ball 2.
With reference to Fig. 2, main groove the right and left in gearshift actuator main body respectively increases a secondary groove, that is to say in gearshift actuator main body and have three grooves, when neutral gear position, be the same with existing gearshift actuator, in the groove that the gearshift elastic steel ball mediates, when other gears, the gearshift elastic steel ball has been controlled the position of gearshift elastic steel ball when other gears by the indentation limitations that shifting actuator main body increases newly, has improved the shifting comfort of car load.
