Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 1, it is a kind of automobile variable speed gear level assembly static test device, including testing stand 1 and is arranged on testing stand 1
On fixed mechanism and load maintainer, the fixed mechanism is used to fix the bracket component 14 of gear shift bar assembly 15, described
Load maintainer includes load bar 2, elastic element 3 and connector sleeve 4, is connected between 2 one end of load bar and testing stand 1 by articulate
It connecing, 3 one end of elastic element is connected on load bar 2, and the other end is connected with connector sleeve 4, and connecting hole 10 is provided on connector sleeve 4,
Limited position mechanism is set on the testing stand 1, and position-limit mechanism is used to limit the movement position of load bar 2.
The fixed mechanism includes the side shield 6 and rear baffle 7 that are fixedly mounted on testing stand 1, is provided on rear baffle 7
Locating rod 8 and top baffle 9, the locating rod 8 are stretched into the hole cooperation on bracket component 14 in bracket component 14, the side shield
6th, rear plate washer 7 and top baffle 9, which respectively coordinate the side plate of bracket component 14, back plate and top plate, positions, limit bracket component 14
Movement.
The position-limit mechanism is the gag lever post 5 being fixedly mounted on testing stand 1, and gag lever post 5 is located at 2 lower section of load bar.
Such as Fig. 2, when being tested using the device gear shift bar assembly, gear shift bar assembly is placed into experiment
On platform 1, the bracket component of gear shift bar assembly is positioned by side shield 6, at this time in locating rod 8 and bracket component 14
Hole be located on same axis, promote bracket component 14 backward along side shield 6, make locating rod 8 through on bracket component 14
Hole is stretched into bracket component 14, while the back plate of bracket component 14 is close to rear baffle 7, and the top plate of bracket component 14 is with fending off at this time
It is fitted closely between plate 9, so far completes the fixed installation to gear shift bar assembly 15；Connector sleeve 4 is passed through into connecting hole 10
13 head of gear level is sleeved on, makes to connect between elastic element 3 and gear level 13, pulls load bar 2 downwards, elastic element 3 is drawn
Stretch, elastic element 3 acts on a tangential elastic pulling force on gear level 13, load bar 2 due to being limited be subject to gag lever post 5,
It rotates down after a certain distance in the position stop motion of gag lever post 5, elastic element 3 is stretched a fixed length at this time
Degree, according to the characteristic of elastic element, elastic element 3 provides a constant elastic force in the position, that is to say, that elastic element 3
A constant elastic pulling force is provided to gear level 13 in the position, the size of this elastic pulling force is exactly to test gear shift bar
Test force needed for assembly 15.By changing the coefficient of elasticity of elastic element 3 or the restraining position of position-limit mechanism can be realized pair
The adjustment of required test force value.
The elastic element 3 uses Hookean spring, and Hookean spring is advantageous in that its coefficient of elasticity is a fixed value so that
It is more convenient in the selection of elastic element and the setting of restraining position.
It is connected respectively by cable wire 12 between the elastic element 3 and load bar 2 and connector sleeve 4, by between three
Flexible connection preferably realizes the transmission of interaction force, improves and act on the stability of loading force and one on gear level 13
Cause property.
Such as Fig. 3, spacer 11 is provided in the connecting hole 10 of the connector sleeve 4, spacer 11 is fixedly mounted in connecting hole 10
Wall, the spacer 11 use nonmetallic materials；Using spacer 11 made of nonmetallic materials, connector sleeve 4 and gear level 13 it
Between when connecting, contacted directly between spacer 11 and gear level 13, play protection gear level 13 and increase connection friction between the two
The effect of power can prevent from falling off between connector sleeve 4 and gear level 13 in loading procedure.
The detection process of the device is：Gear shift bar assembly is fixed on testing stand by fixed mechanism first
Then positioning connects gear level by connector sleeve, pulls load bar downwards, elastic element, which is stretched, loads gear level,
When load bar moves to the position of gag lever post, whether rotate between the gear in observation gear shift bar assembly, if occurring
Rotation then illustrates that product is unqualified, and product qualification is illustrated if not rotating.
The present invention specification and drawings be considered as it is illustrative and not restrictive, on the basis of the present invention, ability
