Abstract
The utility model discloses a gear-shifting self-locking three-shaft five-gear manual speed changing box, and comprises a casing, an ejection push rod, a limiting steel ball and a rolling steel ball which are all arranged in a gear-shifting self-locking device. Two ends of the casing are provided with holes, and the ejection push rod which is arranged in one end of the casing is provided with a compression spring. The ejection push rod penetrates out of the hole arranged at one end of the casing, the end portion of the ejection push rod arranged outside the casing is an arc-shaped surface, the limiting steel ball is arranged in the arc-shaped surface, and the rolling steel ball is arranged between the arc-shaped surface and the limiting steel ball. The other end of the casing is connected with a position switch, and the ejection push rod is contacted with the position switch. Because the gear-shifting self-locking device and the position switch for the gears of the speed changing box are integrated, different position signals are sent out by utilizing the motion of the ejection push rod when a gear self-locking device of the speed changing box shifts gears. Accordingly, the structure arrangement is more reasonable, and the space of the structure is greatly saved.
Description
Technical field
The utility model relates to a kind of manual transmission, is specifically related to the moving gearbox of three five blocks of a kind of gearshift self locking type.
Background technique
The speed changer that different automobile types disposed from the present market mainly is divided into: manual transmission (MT), automatic transmission (AT), manual speed changer (AMT), stepless speed variator (CVT).
For the moving gearbox (MT) of three five blocks, generally all be provided with operating handle gearshift self-locking dress, in the process of putting into gear, promote distance that shift fork moves forward and backward when not enough if handle speed change lever, gear can not influence the life-span of gear in engagement on the facewidth fully.Even reach complete facewidth engagement, also maybe be owing to reasons such as thumps, the gear generation moves axially and has reduced gear meshing length, even breaks away from engagement fully.In order to prevent the generation of this situation, so self-locking device should be set.
The present operating mechanism of transmission assembly all need realize usually shifting gears auto-lock function and neutral, signal output function such as reverse gear.Usually gearshift self-locking mechanism and neutral, reverse gear etc. the signal output function be to realize through different mechanisms respectively.Signal output apparatus and gear self-locking device such as be neutral, reverse gear is two devices independently.Arrangement of parts is difficult like this.
The model utility content
In order to overcome above-mentioned deficiency, the purpose of the utility model is to provide a kind of three five blocks of gearshift self locking type that make the gearshift self-locking device have signal output function and reasonable structural arrangement moving gearbox.
To achieve these goals, the technological scheme below the utility model adopts:
The moving gearbox of three five blocks of gearshift self locking type comprises housing, propulsion arm, spacing steel ball and rolling steel balls in the gearshift self-locking device, the two ends perforate of said housing; Propulsion arm is located in the end of housing, establishes pressure spring on the propulsion arm, and propulsion arm passes from housing one stomidium; The end of the propulsion arm outside housing is a cambered surface, and a steel ball of limiting in the cambered surface is provided with rolling steel balls between cambered surface and the spacing steel ball; The other end of housing is connected with position switch, and propulsion arm contacts with position switch.
The switch push rod of said position switch stretches in the housing, and its end face contacts with propulsion arm, establishes Returnning spring on the switch push rod.
The beneficial effect of the utility model: because the gearshift self-locking device and the position switch of gearbox gear integrated, different position signals is sent in the action of propulsion arm when utilizing the gearshift of gearbox gear self-locking device; Its structural configuration is ingenious rationally, and level of integration is high, saves arrangement space greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, gearshift shifting block; 2, rolling steel balls; 3, spacing steel ball; 4, propulsion arm; 5, pressure spring; 6, Returnning spring; 7, switch push rod; 8, gear box casing; 9, housing; 10, position switch; 11, groove.
Embodiment
As shown in Figure 1, the moving gearbox of three five blocks of gearshift self locking type comprises housing 9, propulsion arm 4, spacing steel ball 3 and rolling steel balls 2 in the gearshift self-locking device; Said housing 9 two ends perforates, propulsion arm 4 is located in the end of housing 9, establishes pressure spring 5 on the propulsion arm 4; Propulsion arm 4 passes from housing one stomidium, and the end of the propulsion arm 4 outside housing is a cambered surface, the steel ball 3 of limiting in the cambered surface; Be provided with rolling steel balls 2 between cambered surface and the spacing steel ball 3, spacing steel ball 3 contacts with gearshift shifting block 1; Propulsion arm 4 is axially established groove 11.Position switch 10 is located at the other end of housing 9, and the switch push rod 7 of position switch 10 stretches in the housing 9, and its end face is enclosed within propulsion arm 4 grooves.Establish Returnning spring 6 on the switch push rod 7.Housing 9 is enclosed within the gear box casing 8.
Working principle: when transmission assembly is shifted gears; Gear level is around self center rotation, and rolling steel balls can fall into two dotted line steel balls of figure position respectively, and is different apart from the distance at center with the steel ball contact surface; Make spring seat be in different positions; Switch assembly contacts with spring seat through the switch push rod, sends different position signals. and component gearshift shifting block 1 is rigidly connected with the gear level of gearbox, under the effect of gearshift power, rotates around the gear level center.In rotating process, rolling steel balls 2 contacts with the different curved sections of component gearshift shifting block 1, and pressure spring 5 produces the feel power; After gearshift puts in place; Rolling steel balls 2 can fall into two dotted line steel balls of figure position respectively, and is different apart from the distance at center with the steel ball contact surface, makes spring seat be in different positions; Switch assembly contacts with spring seat through the switch push rod, sends different position signals.
Claims (2)
1. the moving gearbox of three five blocks of a gearshift self locking type comprises housing, propulsion arm, spacing steel ball and rolling steel balls in the gearshift self-locking device, the two ends perforate of said housing; Propulsion arm is located in the end of housing; Establish pressure spring on the propulsion arm, propulsion arm passes from housing one stomidium, and the end of the propulsion arm outside housing is a cambered surface; A steel ball of limiting in the cambered surface; Be provided with rolling steel balls between cambered surface and the spacing steel ball, it is characterized in that: the other end of housing is connected with position switch, and propulsion arm contacts with position switch.
