Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of commercial vehicle clutches, in particular to a torsion spring type separation device. Background Art
[0002] At present, my country's commercial vehicle sector generally uses pull-type separation or push-type separation devices between the clutch and the transmission. The working principle of the push-type separation device is as follows: the driver steps on the clutch pedal, and the force is transmitted to the separation fork through the power pump and other related components. The separation fork pushes the release bearing forward to press the clutch to achieve separation. When the driver releases the clutch pedal, the separation fork retreats, and it is necessary to drive the release bearing to move backward to allow the clutch to engage, thereby achieving the reconnection of the power of the engine and the transmission. In the common push-type separation device, the connection method between the release bearing and the release fork is "pin-slot type", in which the pins on both sides of the release fork clamp the vertical grooves on both sides of the release bearing, and pull the release bearing back to achieve clutch engagement.
[0003] The disadvantages of this connection method are obvious:
[0004] The separation stroke is limited and stuck: the distance between the contact surface of the separation fork and the pin will change during the separation process, while the distance between the contact surface of the release bearing and the slot is fixed, resulting in the disadvantages of sticking and stroke limitation in this connection mode, which cannot meet the universal application requirements;
[0005] The separation process is not gentle enough: Since the pin and the slot are rigidly connected, vibration and abnormal noise always occur during the pulling process, and the driver's subjective experience is very poor;
[0006] The life of the separation device is insufficient: the rigid connection is affected by vibration for a long time, resulting in insufficient life of the pin, affecting product quality.
[0007] High cost: The release bearing requires a vertical groove with very high machining precision, which results in high production cost. Utility Model Content

[0015] Furthermore, the diameter of the mounting hole corresponds to the diameter of the two end portions of the torsion spring.

[0032] The utility model is further described in detail below with reference to the accompanying drawings:
[0033] The utility model aims to provide a torsion spring type separation device to solve the technical problems of stagnation and travel limitation in the separation process in the prior art.
[0034] See also Figure 1 and Figure 2 In one embodiment of the utility model, a torsion spring type separation device is provided, including a release bearing 1, a release fork 2 and two sets of torsion springs 3; the release fork 2 is provided with two sets of connecting ends, the assembly end of the release bearing 1 is inserted into the two sets of connecting ends of the release fork 2, and the two sides of the assembly end of the release bearing 1 are connected to the two sets of connecting ends of the release fork 2 respectively through two sets of torsion springs 3.
[0035] Specifically, mounting holes 4 are respectively provided on both sides of the assembly end of the release bearing 1 and the two sets of connection ends of the release fork 2. One end of the torsion spring 3 is inserted into the mounting hole 4 of the assembly end of the release bearing 1, and the other end is inserted into the mounting hole 4 of the connection end of the release fork 2. The torsion spring 3 is used for connection without slotting. It only needs to set the mounting holes 4 on the release bearing 1 and the release fork 2, and insert the two ends of the torsion spring 3 into the mounting holes 4 of the release bearing 1 and the release fork 2 respectively, so as to complete the connection. The assembly is done by order, and the processing cost is low.
[0036] Specifically, the mounting hole 4 at the connection end of the release fork 2 is provided through, so that the end of the torsion spring 3 can completely pass through the mounting hole 4, thereby ensuring the stability of the connection between the torsion spring 3 and the release fork 2 and preventing the torsion spring 3 from falling off.
[0037] Specifically, the positions of the mounting holes 4 on both sides of the assembly end of the release bearing 1 and the two sets of connecting ends of the release fork 2 correspond to each other on the same horizontal line, making the separation process smoother and ensuring the stability of the separation operation.
[0038] Specifically, the two ends of the torsion spring 3 are bent and used to be inserted into the mounting holes 4 at the assembly end of the release bearing 1 and the connecting end of the release fork 2, thereby ensuring the assembly stability of the torsion spring 3 inserted into the mounting holes 4 at the assembly end of the release bearing 1 and the connecting end of the release fork 2, and avoiding the separation fork from falling off due to the torsion spring 3 not being installed properly, thereby affecting the separation operation.
[0039] Specifically, the diameter of the mounting hole 4 corresponds to the diameter of the two end portions of the torsion spring 3 , thereby ensuring the stability of the torsion spring 3 when assembled in the mounting hole 4 .
[0040] Specifically, the two groups of torsion springs 3 have the same structure, size and length, and the torsion spring connection is a flexible connection, which greatly improves the service life compared to the traditional pin rigid connection.
[0041] Specifically, the two groups of torsion springs 3 are respectively on both sides of the assembly end of the release bearing 1 and between the two groups of connecting ends of the release fork 2 with opposite rotation directions, ensuring that the separation process is smoother and improving the separation operation performance between the release bearing and the release fork.
[0042] In the present invention, the diameter of the assembly end of the release bearing 1 corresponds to the spacing between the two groups of connecting ends of the release fork 2, and the lengths of the two groups of connecting ends of the release fork 2 are the same.
[0043] The working process of a torsion spring type separation device provided by the utility model is as follows:
[0044] 1) First, bend the torsion spring 3 by 90 degrees and insert the two ends into the holes of the release bearing 1 and the release fork 2 respectively. Pay attention to distinguish the left and right torsion springs (with different rotation directions), and the installation is complete;
[0045] 2) Separation process: The front end of the release fork 2 presses against the rear end of the release bearing 1 and pushes forward. The clutch is pressed by the release bearing and then separated.
[0046] 3) Engagement process: the release fork 2 rotates backward, and the release bearing 1 is driven backward by the elastic force of the torsion spring 3. The elasticity of the torsion spring 3 itself can absorb the vibration during the process to ensure smooth engagement.
[0047] 4) During the whole process, the release fork 2 and the release bearing 1 have no travel limit and no stuck point, so the user experience is good, the production cost is low, and the service life is long.
[0048] To summarize, the utility model provides a torsion spring type separation device, in which the assembly end of the release bearing is inserted into the two sets of connecting ends of the release fork, and the two sides of the assembly end of the release bearing are connected to the two sets of connecting ends of the release fork by two sets of torsion springs respectively. When the release fork pulls the release bearing backward through the torsion spring, the elasticity of the torsion spring itself can absorb and filter out the vibration in the process, thereby ensuring that the separation process is smooth and silky. Due to the elasticity of the torsion spring, there is no travel limitation or card point in the separation process, so it is suitable for all separation situations and improves the separation operation performance.
