Description

Joint ring assembly convenient to assemble

Technical Field

The utility model belongs to car cable part especially relates to a convenient assembly joint ring subassembly.

Background

The automobile cable is used as an important component of an automobile, and plays a role in transmitting motion energy (force and displacement), so that remote control is realized. The design direction of new motorcycle type is closing to user's demand increasingly, and user experience becomes the first factor of consideration, promotes to control and feels, increases interior trim space and becomes the development trend. And along with the increasing requirement of automobile host factory to the convenience of part installation and dismantlement, joint ring combination adopts traditional processing methods such as riveting, can cause the destruction to the part in the dismantlement process and can not satisfy customer's demand, and a follow up car development trend more agrees with car drive mechanism, and the design of more stable and convenient to dismantle joint ring combination is urgent.

In the prior art, as shown in fig. 4, a connecting rod 8 in a joint ring assembly passes through a gasket 9 and a joint sleeve 7, and a press riveting mode is adopted, so that the part of the connecting rod 8 higher than the gasket 9 is deformed, and the size of the part is larger than the inner holes of the gasket 9 and the joint sleeve 7, thereby achieving the purpose of limiting the connecting rod 8 from disengaging. As shown in fig. 5, the joint sleeve 7 is designed in an oval shape, and the larger size of the joint sleeve is easy to interfere with the surrounding environment of the inhaul cable, so that the performance of the inhaul cable is affected. After the connecting rod 8 is riveted and formed, only a special disassembling tool can be used, and parts can be damaged and cannot be quickly switched. Because of the connecting rod 8 quality is too light among the former technical scheme, only 15g leads to its natural frequency too high, because of the combination of joint ring uses the nut to fix on automobile transmission, the vibration that produces in the gearbox operation process transmits to the combination of joint ring, and the high-speed vibration of combination of joint ring easily makes the nut lax, produces the risk that the cable became invalid to because of joint ring combination quality is too light, the user is promoting the gear level and makes, and the feedback is felt relatively poorly.

Disclosure of Invention

The utility model provides a joint ring component which is convenient to assemble, which solves the problems that the prior joint ring component is easy to interfere with the surrounding environment of a guy cable, is inconvenient to disassemble, has overhigh natural frequency and has poor feedback hand feeling,

the utility model discloses the technical scheme who takes is, adapter sleeve and joint pole fixed connection, bush and adapter sleeve interference fit, round pin axle and bush clearance fit, split pin and round pin axle lower extreme cross-under, the packing ring cup joints at round pin axle lower extreme, and is located between split pin and the bush.

The joint sleeve is circular.

The weight of the pin shaft is 32-34 g.

The utility model has the advantages that the structure is novel, the risk of interference is avoided by adopting the circular joint sleeve, and the structure and the size are more fit with the automobile gearbox; the split pin connection mode is adopted, so that the disassembly is more convenient; increase round pin axle weight, make self natural frequency reduce, reduce the cable risk of inefficacy, increase user experience simultaneously.

Detailed Description

The joint sleeve 1 is fixedly connected with the joint rod 2, the bush 3 is in interference fit with the joint sleeve 1, the pin shaft 4 is in clearance fit with the bush 3, the cotter pin 6 is connected with the lower end of the pin shaft 4 in a penetrating way, and the gasket 5 is sleeved at the lower end of the pin shaft 4 and is positioned between the cotter pin 6 and the bush 3;

the joint sleeve 1 is circular;

the weight of the pin shaft 7 is 32-34 g.

The working principle is as follows:

as shown in fig. 1 to 5, the oval joint sleeve in the original technical scheme is optimized to be round in the technical scheme, so that interference between circumferential rotation and the surrounding environment of the inhaul cable is avoided, in order to ensure the overall strength, a bush 3 is added in a pin shaft 4 and a joint sleeve 1, the pin shaft 4 and the bush 3 are in clearance fit, the joint sleeve 1 and the bush 3 are in interference fit, and the part clearance between the pin shaft 4 and the joint sleeve 1 is eliminated; the split pin 6 is adopted to replace the press riveting processing technology of the original technical scheme, the assembly and disassembly are only carried out by using common pliers, and parts are not damaged; the mass of the pin shaft 7 is increased by 1 time compared with that of the connecting rod 2 in the prior technical scheme, the mass is increased to 32 g-34 g from 15g, the natural frequency of the joint ring assembly is reduced, the gear shifting feedback feeling transmitted to a user is moderate, and the user experience is increased.
