Problems solved by technology

If the lubricating grease solidifies, when the engine is started, the release bearing will have a high starting torque. Such a high starting torque will cause the preload spring to break away from the slave cylinder, and even cause the slave cylinder to fail to work.

Embodiment Construction

[0029] It can be seen from the background art that there is a risk that the slave cylinder cannot work normally at low temperature.

[0030] Please refer to Figure 1-Figure 3 , figure 1 is a sectional view of a slave cylinder; figure 2 yes figure 1 Schematic diagram of the position of the retaining ring and preload spring in ; image 3 yes figure 2 The partially enlarged schematic diagram of the dotted box A.

[0031] As shown in the figure, a slave cylinder includes a release bearing 7, a retaining ring 1, a preload spring 3 and a piston 2. The inner ring of the release bearing 7 is sleeved on the outer ring surface of the retaining ring 1, and the spring of the preload spring 3 One end of the wire is fixed on the boss 5 on the inner ring surface of the retaining ring 1, and is in contact with the boss surface 6 of the boss 5, and the other end of the spring wire of the preload spring 3 is fixed on the housing seat (not shown in the figure). )superior. The preload s...

Abstract

The invention discloses a vehicle, separation device and a driven cylinder. The driven cylinder comprises a retainer ring, a preloading spring and an elastomer, wherein a stop part is arranged in theperipheral direction of the retainer ring; a first end of the preloading spring axially butts against the retainer ring; a first end of the elastomer butts against the stop part; and a second end of the elastomer butts against the end part of a spring wire at the first end of the preloading spring. In the driven cylinder, the elastomer is arranged between the retainer ring and the preloading spring, so that the separation of the retainer ring from the preloading spring caused by startup of an engine at low temperature can be prevented, the normal work of the driven cylinder at low temperatureis guaranteed, and the cost is lower.

Description

technical field [0001] The embodiment of the present invention relates to the field of hydraulic technology, in particular to an automobile, a separation device and a slave cylinder. Background technique [0002] The disengagement of the vehicle clutch is usually carried out by means of the release bearing of the concentric slave cylinder (CSC), through which the annular piston of the slave cylinder actuates the diaphragm spring elastic element of the vehicle clutch. The preload spring preloads the release bearing to press the release bearing against the clutch diaphragm spring. [0003] At lower temperatures, the grease inside the release bearing may solidify. If the lubricating grease solidifies, when the engine is started, the release bearing will have a high starting torque. Such a high starting torque will cause the preload spring to break away from the slave cylinder, and even cause the slave cylinder to fail to work. [0004] Therefore, how to ensure the normal oper...
