Description

Technical Field

[0001] The technical solution relates to the technical field of automobile driven disc assemblies, and in particular to a driven disc device with a built-in idle speed. Background Art

[0002] Urban public transportation is becoming more and more mature, especially bus transportation. Fuel-powered city buses basically use 420 / 430 clutches, and most of their pressure plate assemblies are lever-type. Due to the limitations of their release levers, their matching driven plate assemblies are often unable to use conventional idle damping driven plates, but can only use ordinary driven plates. Ordinary driven plates do not have an idle function, which leads to a series of problems such as start-up jitter, abnormal noise, unclear separation, and uneven jitter during driving. At the same time, the original conventional 420 / 430 driven plate idle speed is an external idle speed, and the idle speed setting on the damping plate will be very high. The idle speed will interfere with the release lever of the pressure plate assembly, thereby affecting the operation of the driven plate. Utility Model Content

[0003] The purpose of this technical solution is to provide a driven disk device with built-in idle speed, by embedding the idle speed module in the driven disk module, so as to solve the problem that the idle speed module will interfere with the driven disk module when it is externally mounted on the driven disk module.

[0004] The purpose of this technical solution is achieved in this way:

[0007] Preferably, the connecting part is movably engaged with the transmission part through a clamping structure, and the clamping structure includes: a clamping part, which is protrudingly arranged on the peripheral side of the connecting part; and a clamping groove, which is formed on the inner side of the transmission part; wherein the clamping part is movably engaged in the clamping groove, and a buffer gap is provided between the clamping part and the clamping groove.

[0008] Preferably, the driven disc module at least comprises: a disc hub assembly, the idle module is arranged on the disc hub assembly; and a plurality of shock absorbing springs, which are arranged on the disc hub assembly.

DETAILED DESCRIPTION

[0021] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the idle module 1 of the existing driven disc device including the idle function is placed outside the driven disc and located at the center of the driven disc. The idle module 1 has a plurality of idle springs 6 arranged on the surface of the outer disc hub 15. Since the idle spring 6 itself has a certain height, after being arranged on the surface of the outer disc hub 15, it will cause motion interference with the other components of the driven disc device, thereby affecting the normal use of the driven disc.

[0023] like Figure 2 and Figure 3 As shown, the driven disk device includes: an idle module 1, which is used to connect to a power source; and a driven disk module 2, which is arranged on the idle module 1 and can move with the idle module 1; wherein, the idle module 1 includes: a connecting part 3, which has a connecting hole 4, and the connecting hole 4 is used to connect to a power source; a transmission part 5, which is movably clamped outside the connecting part 3 and can move with the connecting part 3; and at least one idle spring 6, which is arranged between the connecting part 3 and the transmission part 5, and simultaneously movably abuts against the connecting part 3 and the transmission part 5; wherein, the connecting part 3 pushes the transmission part 5 to move through the idle spring 6.

[0024] The driven disk module 2 is generally configured the same as the original structure, the difference being the structure of the idle module 1 and its position on the driven disk module 2. The idle module 1 is placed at the center of the driven disk, and can be driven by a power source to work, and drive the driven disk module 2 to work.

[0025] Specifically, the connecting part 3 is movably connected to the transmission part 5, and the clamping part 9 is fixedly connected to the driven disk module 2. When the connecting part 3 is driven to rotate by the power source, the clamping part 9 rotates along with it and drives the driven disk module 2 to work. During this process, the idle spring 6 performs idle work.

[0026] like Figure 3 and Figure 4 As shown, the connecting portion 3 is recessed to form at least one mounting groove 7, and the transmission portion 5 is recessed to form at least one mounting groove 8. The mounting groove 1 7 and the mounting groove 2 8 cooperate to form a mounting position, and the idle spring 6 is placed in the mounting position.

[0027] The mounting groove 1 7 and the mounting groove 2 8 are used to place the idle spring 6. The idle spring 6 can abut the connecting part 3 and the transmission part 5 at the same time. When the connecting part 3 rotates, it preferentially compresses the idle spring 6, and the transmission part 5 rotates through the power transmission of the idle spring 6.

[0028] like Figure 3 and Figure 4 As shown, the connecting part 3 is movably engaged with the transmission part 5 through a clamping structure, and the clamping structure includes: a clamping part 9, which is protrudingly arranged on the peripheral side of the connecting part 3; and a clamping groove 10, which is formed on the inner side of the transmission part 5; wherein the clamping part 9 is movably engaged in the clamping groove 10, and a buffer gap is provided between the clamping part 9 and the clamping groove 10.

[0029] When the idle module 1 is working, the idle spring 6 is always in a compressed state, and in order to increase the connection stability between the connecting part 3 and the transmission part 5, a clamping structure is provided, which can make the power transmission more stable and ensure that the connecting part 3 and the transmission part 5 will not idle.

[0030] like Figure 3 As shown, the inner hub 13 is provided with a plurality of positioning pins 19 , and the positioning pins 19 cooperate with each other to form a positioning area, and the idle module 1 is placed in the positioning area. The inner hub 13 is also provided with a plurality of positioning ring pieces 20 , and the positioning ring pieces 20 are sleeved outside the idle module 1 .

[0031] The design of the positioning pin 19 and the positioning ring 20 can increase the stability of the idle module 1 placed on the driven disc module 2 .

[0032] like Figure 2 and Figure 3 As shown, the driven disc module 2 at least comprises: a disc hub assembly 11, the idle module 1 is arranged on the disc hub assembly 11; and a plurality of shock-absorbing springs 12, which are arranged on the disc hub assembly 11, and the disc hub assembly 11 at least comprises: an inner disc hub 13, a mounting hole 14 is provided at the center thereof, and the idle module 1 is placed in the mounting hole 14; an outer disc hub 15, which is arranged on the side of the inner disc hub 13 through a pin body; and a disc hub cover shell 16, which is connected to the transmission part 5 through a rivet 17.

[0033] The rivet 17 is used to fix the connecting disk hub cover 16, the inner disk hub 13 and the transmission part 5. The idle module 1 drives the outer disk hub 15 to rotate through the inner disk hub 13 and the disk hub cover 16. When the outer disk hub 15 rotates, the shock absorbing spring 12 works. The disk hub cover 16 preferably pushes the shock absorbing spring 12 for buffering, and then drives the outer disk hub 15 to rotate.

[0034] like Figure 2 and Figure 3 As shown, the inner hub 13 and the hub cover 16 are both provided with mounting grooves 18 for mounting the shock absorbing spring 12 .

[0035] The shock absorbing spring 12 abuts against the inner hub 13 and the hub cover 16 at the same time, so it can play a shock absorbing role.

[0036] The above shows and describes the basic principle and main features of the technical solution and the advantages of the technical solution. The technicians in this industry should understand that the technical solution is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the technical solution. Without departing from the spirit and scope of the technical solution, the technical solution will have various changes and improvements, which fall within the scope of the technical solution to be protected.
