Embodiment 1

[0024] like figure 1 and figure 2 As shown, a push rod displacement monitoring mechanism of a vehicle clutch includes a clutch 1, a push rod 2, a rotating column 3 and an encoder 4, the push rod 2 is slidably installed on the clutch 1, and the push rod 2 is connected to the separation rocker of the clutch. The arm 5 and the push rod 2 can receive the thrust transmitted by the clutch pedal and the release rocker arm 5 to squeeze the diaphragm spring 6 of the clutch to produce deformation. The rotating column 3 is rotatably mounted on a bracket 7 of the vehicle chassis, the rotating column 3 is located on the side of the push rod 2, and an encoder 4 for detecting the rotation angle of the rotating column 3 is installed on the rotating column 3. The top of the rotating column 3 The central key is connected to a connecting rod 8, the other end of the connecting rod 8 is provided with a follower 9, and the push rod 2 is formed with an arc-shaped main limit groove 10 that cooperat...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 lies in the difference in the dustproof structure, such as image 3 As shown, the monitoring mechanism nails or glues an accordion-shaped dust cover 17 on the convex surface 13 of the connecting rod. The material of the dust cover 17 is a flexible waterproof fabric, and the dust cover 17 can cover the main limit groove 10. Among them, two dustproof covers 17 are symmetrically installed on the convex surface 13. One end of the dustproof cover 17 is fixed at the arc-shaped end of the main limiting groove 10, and the other end is fixed on the connecting rod 8. When the connecting rod 8 rotates The dust cover 17 can be stretched or folded alternately, for example: when the connecting rod 8 folds the left dust cover, the right dust cover is automatically stretched by the connecting rod, so that the main limit groove 10 is always protected from dust The cover 17 covers and isolates the dust from entering the groove.

Abstract

The invention provides a push rod displacement monitoring mechanism of a vehicle clutch, comprising a clutch and a push rod, the push rod is slidably mounted on a casing of the clutch, and the push rod receives the thrust transmitted from the clutch pedal to squeeze the diaphragm spring of the clutch It is characterized in that it also includes a rotating column and an encoder, the rotating column is rotatably installed on a bracket of the chassis, the rotating column is located on the side of the push rod, and an encoder for detecting the rotation angle of the rotating column is installed on the rotating column. A connecting rod is installed in the center of the top of the rotating column, and the other end of the connecting rod is provided with a follower. The push rod is formed with an arc-shaped main limit groove that cooperates with the follower. The main limit groove and the rotating column have the same center of circle. The follower is inserted into the main limit slot, and when the push rod is translated in translation, the follower of the connecting rod makes an arc-shaped movement track along the main limit slot to drive the rotating column to rotate. The invention can solve the problems that the structure of the existing push rod displacement monitoring mechanism is not compact enough and the detection accuracy needs to be improved.

Description

technical field [0001] The invention belongs to the technical field of clutches, and particularly relates to a push rod displacement monitoring mechanism of a vehicle clutch. Background technique [0002] The clutch is a common component in automotive mechanical transmission. It is located in the flywheel housing between the engine and the transmission. The driver can depress or release the clutch pedal to separate or engage the engine and the transmission. The basic requirements for vehicle clutches are: stable and reliable power transmission performance, smooth engagement, rapid and thorough separation; convenient adjustment and repair; small size and compact structure; good wear resistance and sufficient heat dissipation capacity; convenient and labor-saving operation. [0003] Among them, the power transmission performance of the clutch is a key requirement for the quality of the clutch. The power transmission status of the clutch in the process of separation and couplin...
