Description

Technical Field

[0001] The utility model relates to the technical field of overrunning clutch devices, in particular to an automobile overrunning clutch with low noise and wear resistance. Background Technique

[0002] An electric starting overrunning clutch (also known as an overrunning clutch), also known as a "ratchet", is a device that transmits the power of an automobile engine to the axle in a switching manner. When a gasoline engine-powered vehicle is running, the engine keeps running. However, to meet the requirements of vehicle driving, the vehicle must have actions such as stopping and shifting gears. Therefore, a set of mechanisms must be added at the external connection of the engine to interrupt the power transmission as needed, so as to achieve the actions of making the vehicle stationary or shifting gears while the engine keeps running.

[0003] The application number is CN202221864602.8, which discloses a low-noise and wear-resistant automobile overrunning clutch, including a transmission shaft. The outer wall of the transmission shaft is in clearance fit with a mounting seat. The mounting seat is rotationally connected to the transmission shaft through a bearing. An oil injection mechanism is provided on the mounting seat, and a noise reduction mechanism is provided on the mounting seat. For this low-noise and wear-resistant automobile overrunning clutch, through the cooperation between the oil injection mechanism and the transmission shaft, when the transmission shaft is driven by an external force at the mounting seat and rotates, the transmission shaft can drive the balls at the pipe body to rotate. When the balls rotate, the lubricating oil transferred from the inside of the box body into the pipe body will be coated on the surface of the transmission shaft and the bearing. Thus, self-lubrication can be achieved between the bearing and the transmission shaft, eliminating the need for regular manual oil injection, effectively avoiding forgetting to pour lubricating oil, which may cause the wear rate of the transmission shaft to accelerate and generate noise when the transmission shaft is transmitting power at the mounting seat, thereby improving the working stability of the overrunning clutch.

[0004] The low-noise and wear-resistant automobile overrunning clutch disclosed in the above document has the following defects: When this overrunning clutch is installed in a vehicle for use, it needs to be installed on the transmission shaft for rotational cooperation. Since the overrunning clutch needs to rotate continuously, it needs to continuously rub against the transmission shaft. However, this overrunning clutch does not have components that can be stably matched, resulting in insufficient endurance of the overrunning clutch and being easily damaged.

[0005] It can be seen that the existing automobile overrunning clutch does not have the function of high wear resistance, and it is necessary to improve the existing deficiencies to provide a function of high wear resistance. Content of the Utility Model

[0006] The purpose of the utility model is to provide an automobile overrunning clutch with low noise and wear resistance to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a low-noise and wear-resistant automotive one-way clutch, which includes a fixed structure and a one-way clutch assembly. The one-way clutch assembly is installed on the inner wall of the fixed structure. The fixed structure includes a tooth block. Four tooth groove lock washers and friction plates are sleeved on the outer wall of the tooth block. The four tooth groove lock washers and friction plates are arranged alternately on the outer wall of the tooth block. The four tooth groove lock washers are meshed with the tooth block.

The outer ring of the tooth groove circle is inserted into the middle circular groove of the housing. A number of slots and card slots are provided on the outer wall of the housing. The number of slots and card slots are alternately distributed around the housing. The purpose of such a setting is that during the use of the one-way clutch, the tooth block fixes the housing through the outer ring of the tooth groove circle.

[0011] Further, a number of bumps on the three friction plates are on the inner walls of a number of slots. A number of bumps on the friction plate farthest from the housing are on the inner walls of the card slots. The purpose of such a setting is that during the use of the one-way clutch, the friction plate is inserted into the slot through the bump, so that the bump is fixed. Through the misaligned insertion of the bumps at the last row of friction plates into the card slots of the housing.

[0012] Further, a mounting plate is inserted on the inner wall of the housing. A toothed block ring is provided on one side of the mounting plate. The toothed block is meshed with the toothed block ring. Four screw rods are threadedly connected to the inner wall of the middle of the mounting plate. The rod bodies of the four screw rods penetrate through the concave blocks. The purpose of this setting is that during the use of this one-way clutch, the four groups of tooth groove lock plates and friction plates are fixed by the cooperation of the positioning plate and the screw rods.

[0013] Further, a compression spring and a positioning plate are sleeved on the outer walls of the four screw rods respectively. The positioning plate is on the outer wall of one side of the four positioning blocks. Both ends of the four compression springs are on the outer walls of the mounting plate and the sealing block. The purpose of this setting is that during the use of this one-way clutch, the one-way clutch assembly is limited and fixed on the positioning blocks in the concave blocks through the cooperation of the screw rods and the positioning plate, so that the one-way clutch assembly is fixed in the fixing structure.

[0014] The utility model has the following beneficial effects:
