Abstract
The utility model discloses a novel shock-absorbing and noise-lowering gear level seat structure for a transmission. The gear level seat structure comprises a control lid, a spherical cushion, a gear level, dowel pins, and a large compression ball head. A flexible rubber flat cushion is arranged right below the spherical cushion, the spherical cushion and the rubber flat cushion have different elasticity, and a nylon sleeve is arranged between the control lid and the large compression large ball head. In the utility model, the structure of the original gear shifting seat is not changed, only the dowel pins, the large ball head of the gear level, the nylon sleeve, the rubber flat gasket, and the spherical cushion are optimized, and the shock-absorbing and noise-lowering effects are remarkable.
Description
Technical field
The utility model relates to a kind of new work transmission with damping noise reduction gear level holder structure, belongs to the automobile component field.
Background technology
At present, automobile has been come into huge numbers of families.The gear level holder structure of existing automobile is referring to shown in the accompanying drawing 2; Comprise handle cover 1, be located at handle lid interior compress big bulb 7; And the spring 8 and spring perch 9 that compress big bulb 7; Handle between the bottom of covering and compress big bulb and be provided with ball ring 3, the both sides that compress big bulb are provided with pin 4, and gear level 10 is located at the top that compresses big bulb.
Yet the lower end of the gear level holder structure of said structure is prone to take place the vibrations abnormal sound.Particularly because the requirement of car load discharging is more and more stricter; Driving engine has adopted a large amount of up-to-date technologys at aspects such as improving intake and exhaust, work by combustion; Like MPI multi point injection in inner cylinder direct injection, the cylinder, exhaust turbocharging etc., this feasible effective power with the money driving engine is greatly improved, but has also strengthened engine vibration simultaneously; Cause chassis resonance, cause gear level lower end vibrations abnormal sound.
Summary of the invention
The utility model purpose provides a kind of new work transmission with damping noise reduction gear level holder structure.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of new work transmission is with damping noise reduction gear level holder structure; Comprise and handle lid, ball ring, gear level, pin and compress big bulb; Be provided with the flexible rubber plain cushion under the said ball ring, ball ring is different with the elasticity of flexible rubber plain cushion; Said manipulation is covered and is compressed between the big bulb and is provided with nylon jacket.
In the technique scheme, the head of said pin is provided with cushion rubber.To avoid two side channel direct contacts of itself and the big bulb of gear level.
In the technique scheme, the lateral surface of said nylon jacket is provided with 2 bayonet sockets that cooperate with said pin.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1. the utility model does not change the structure of former gearshift seat, only optimal design big bulb, nylon jacket, rubbery flat gasket and the ball ring of pin, gear level, the damping noise reduction effect is obvious.
The compact conformation of the utility model, be convenient to manufacturing and assembling, interchangeability is strong, and cost low, be suitable for applying.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment one:
Referring to accompanying drawing 1,3, shown in 4, a kind of new work transmission comprises manipulation lid 1, ball ring 3, gear level 10, pin 4 that is connected on the change-speed box rear housing and spring 8 and the spring perch 9 that compresses big bulb 7 with damping noise reduction gear level holder structure; On pin 4, set up cushion rubber 5 referring to accompanying drawing 3, avoided two side channel direct contacts of itself and the big bulb 7 of gear level; In the outside of the big bulb 7 of gear level and handle cover and designed nylon jacket 6 between 1 endoporus, make the big bulb 7 of gear level cover not direct contact of 1 endoporus with manipulation; Cut off the direct friction between metal and the metal like this, effectively reduced the vibrations abnormal sound, two symmetrical circular hole bayonet sockets have been designed referring to accompanying drawing 4 in the end of nylon jacket 6, directly are installed on the pin 4; Reduce the thickness of ball ring, set up flexible rubber plain cushion 2, wherein, rubbery flat gasket 2 adopts soft rubber to process, and has changed the intrinsic vibration frequency at gear level place, has effectively improved the ability of buffering shock-absorbing.
During assembling, cover 1 bottom successively pack into rubbery flat gasket 2, ball ring 3 handling; Pin 4 installs to be riveted on behind the cushion rubber 5 to handle and covers in 1 the pin-and-hole; The circular hole bayonet socket of nylon jacket 6 is aimed at pin 4 down touch, all stick into pin until the circular hole bayonet socket of nylon jacket 6; Spring 8 and spring perch 9 are sleeved on big bulb 7 tops of gear level 10, then spring perch 9 are packed into to handle and cover 1 top.
What should explain is; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
