Abstract
The utility model discloses a position on-off gear sensor in an automatic transmission, which comprises a sensor body, a bushing and a transmission block, wherein the bushing and the transmission block are arranged at the lower end of the sensor body; a through hole matched with the transmission block is formed in the center of the bushing; the transmission block is arranged in the through hole in an up and down sliding manner; and the bushing is fixed with the sensor body. As the bushing and the transmission block are additionally arranged at the lower end of the sensor body, the tangential force on the sensor exerted by the shift fork pole of the automatic transmission can be converted into vertically upward pushing force, which reduces the abrasion of the sensor contact and prolongs the service life of the sensor; moreover, when the transmission block is abraded, all that is needed for continuous use is to replace the transmission block with a new one, so that the maintenance cost in the later period is reduced; and finally, when the position on-off gear sensor is in a neutral position of a high and low gear, the transmission block is in contact with neither the shift fork rod nor the round contact of the sensor, so that the service life of the sensor is further prolonged. Therefore, the position on-off gear sensor is suitable for gearboxes.
Description
Technical field
The utility model relates to the sensor that is used for automatic transmission, particularly relates to a kind of position switch mode gear position sensor that is used for automatic transmission.
Background technique
Before the utility model proposes, in touch sensor, like traditional reverse gear sensor, its direct and shifting fork bar grooves contact in circle contact, lower end.In this structure, the inclined-plane of reverse speed fork is directly justified the contact with sensor and is contacted, and acts on the sphere of round contact perpendicular to the active force on shift fork inclined-plane; Sensor circle contact receives oblique thrust; Like this, sensor circle contact suffered resistance in the process that moves upward is bigger, and produces big frictional force with case of transmission; Finally cause sensor life-time short, easy break-down.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of above-mentioned background technology, to provide a kind of simple in structure, long service life and the position switch mode gear position sensor that is used for automatic transmission easy to maintenance.
In order to realize above purpose; A kind of position switch mode gear position sensor that is used for automatic transmission that the utility model provides, comprising: sensor body is characterized in that; Also comprise the lining and the drive block that are arranged on the sensor body lower end; Said lining center is provided with the through hole that matches with said drive block, and said drive block slides up and down and is arranged in the said through hole, and said lining and sensor body are fixed.
In such scheme, said drive block is a tappet, and the upper-end surface of this tappet is the plane, and its lower end surface is a sphere, and the shifting fork bar with automatic transmission is converted into thrust straight up to the tangential force that sensor applied like this, has reduced the wearing and tearing of sensor contact.
In such scheme; Said drive block is a steel ball; The center of the round contact of the center of this steel ball and sensor body lower end is on same vertical curve, and the shifting fork bar with automatic transmission is converted into thrust straight up to the tangential force that sensor applied like this, has reduced the wearing and tearing of sensor contact.
The utility model and existing technology contrast; Show that fully its superiority is: through adding lining and drive block in the sensor body lower end; The shifting fork bar of automatic transmission is converted into thrust straight up to the tangential force that sensor applied; Reduce the wearing and tearing of sensor contact, improved the working life of sensor; Simultaneously, after the drive block wearing and tearing, the drive block that only need more renew can continue to use, and has reduced the maintenance cost in later stage; At last, when the high and low shift sensor mechanism was in the neutral position of high and low shift, drive block did not contact with shifting fork bar, and drive block does not contact with sensor circle contact yet, has further improved the working life of sensor.
Description of drawings
Fig. 1 is the user mode structural representation of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
Among the figure, sensor body 1, lining 2, drive block 3, through hole 4, automatic transmission shifting fork bar 5, automatic transmission housing 6.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail, but this embodiment should not be construed as the restriction to the utility model.
As shown in Figure 1; Present embodiment provides a kind of position switch mode gear position sensor that is used for automatic transmission; Comprise: sensor body 1, lining 2 and drive block 3; Said lining 2 centers are provided with the through hole 4 that matches with said drive block 3, and said drive block 3 slides up and down and is installed in this through hole 4, and the lower end of said lining 2 upper ends and sensor body 1 is fixed.Said drive block 3 is a tappet, and the upper-end surface of this tappet is the plane, and its lower end surface is a sphere.Certainly, drive block 3 also can be designed to steel ball, the center of the round contact of the center of this steel ball and sensor body lower end on same vertical curve (referring to Fig. 2).
As shown in Figure 2, when the utility model used: elder generation installed to drive block 3 in the through hole 4 of lining 2, then lining 2 is sleeved on the lower end of sensor body 1, the utility model was screwed on automatic transmission housing 6 through lining 2 to get final product at last.
As shown in Figure 1; The utility model is through adding lining 2 and drive block 3 in sensor body 1 lower end; 5 pairs of tangential forces that sensor applied of automatic transmission shifting fork bar are converted into thrust straight up, have reduced the wearing and tearing of sensor contact, improved the working life of sensor; Simultaneously, after drive block 3 wearing and tearing, the drive block 3 that only need more renew can continue to use, and has reduced the maintenance cost in later stage; At last, when the high and low shift sensor mechanism was in the neutral position of high and low shift, drive block 3 did not contact with automatic transmission shifting fork bar 5, and drive block 3 does not contact with sensor circle contact yet, has further improved the working life of sensor.
