Description
Technical field
The utility model relates to a kind of manual car shift of transmission components.
Background technique
In recent years, as national standard requires to improve to fuel economy and client chases after the higher of shifting comfort
It asks, automotive light weight technology and driver comfort promote the important process content for having become each automaker.In manual transmission,
Clump weight has important role for improving shift performance in shift assembly, and the rotary inertia of clump weight is bigger, shift sucking
It is better to feel, and secondary pulse is also lower.For previous shift assembly, clump weight is fixedly connected with control shaft, and clump weight is same
When have the effect for increasing shift inertia and gear-shifting rocker arm, although this structure is simple, the rotation of clump weight relation control axis
Inertia is fixed and invariable, and to increase rotary inertia, and general way is to increase the weight of clump weight, and clump weight weight increases
It will lead to gearbox weight increase, to reduce VE Vehicle Economy, and to will lead to block selecting power not right for the self weight of clump weight
Claim.
Summary of the invention
The purpose of this utility model is to provide a kind of manual car speed changer lever shift assemblies, overcome former shift group
Part increases the shortcomings that rotary inertia way will affect block selecting power, reduction VE Vehicle Economy using clump weight weight is increased.
A kind of manual car speed changer lever shift assembly, it is characterised in that：Including clump weight, clump weight rocker arm, lead
To pin, snap ring, bushing, straight pin, gear-shifting rocker arm, resilient key, gear-shifting ball joint, control shaft, clump weight is riveted on clump weight rocker arm
One end, guide pin is riveted on clump weight rocker arm, and the clump weight rocker arm other end is by bushing and cylinder pin connection, on straight pin
Snap ring is installed in portion, and speed-changer operation lid is fixed on by interference fit in straight pin lower part, and the snap ring on straight pin is matched for limiting
Pouring weight rocker arm is moved axially along straight pin, and one end of gear-shifting rocker arm is provided with guide groove, and the guide pin on clump weight rocker arm is inserted into it
In, gear-shifting ball joint is riveted on the other end of gear-shifting rocker arm, and gear-shifting rocker arm and control shaft pass through elastic pin connection.Clump weight rocker arm is logical
Bushing and cylinder pin connection are crossed, so that the self weight of clump weight is transmitted to speed-changer operation lid, eliminates clump weight self weight to choosing
The influence of shelves power.The guide pin on guide groove driving clump weight rocker arm on gear-shifting rocker arm, to drive clump weight rocker arm around circle
Pin rotation.
The utility model has the advantages that：The utility model is driven on clump weight rocker arm by the guide groove on gear-shifting rocker arm
Guide pin, the revolving speed of clump weight rocker arm is higher than the revolving speed of gear-shifting rocker arm, therefore clump weight is transformed into around the rotary inertia of straight pin
It will be amplified after control shaft, and the rotation speed ratio between clump weight rocker arm and gear-shifting rocker arm is with the increase of gear-shifting rocker arm corner
And increase, therefore the rotary inertia that clump weight is transformed into control shaft will be also gradually increased, and compared with previous structure, be turned on an equal basis
Dynamic inertia, required clump weight is lighter, and as rotary inertia increases, and sucking sense is stronger, and secondary pulse is smaller.This is practical new
Type structure can mitigate clump weight, and enhancing shift sucking sense reduces secondary pulse, eliminates clump weight self weight to the shadow of block selecting power
It rings, meets the requirement of automotive light weight technology design and shift performance boost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the utility model is mounted on speed-changer operation and covers cross-sectional view；
In figure：Clump weight 1, clump weight rocker arm 2, guide pin 3, snap ring 4, bushing 5, straight pin 6, gear-shifting rocker arm 7, resilient key
8, gear-shifting ball joint 9, control shaft 10.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of manual car speed changer lever shift assembly, including clump weight 1, clump weight rocker arm 2, guide pin 3, snap ring
4, bushing 5, straight pin 6, gear-shifting rocker arm 7, resilient key 8, gear-shifting ball joint 9, control shaft 10, clump weight 1 are riveted on clump weight rocker arm 2
One end, guide pin 3 is riveted on clump weight rocker arm 2, and 2 other end of clump weight rocker arm is connect by bushing 5 with straight pin 6, justifies
Snap ring 4 is installed on 6 top of pin, and speed-changer operation lid, the snap ring 4 on straight pin 6 are fixed on by interference fit in 6 lower part of straight pin
It is moved axially for limiting clump weight rocker arm 2 along straight pin 6, one end of gear-shifting rocker arm 7 is provided with guide groove, on clump weight rocker arm 2
Guide pin 3 be inserted, gear-shifting ball joint 9 is riveted on the other end of gear-shifting rocker arm 7, and gear-shifting rocker arm 7 and control shaft 10 pass through bullet
Property pin 8 connect.Clump weight rocker arm 2 is connect by bushing 5 with straight pin 6, so that the self weight of clump weight 1 is transmitted to speed changer behaviour
Vertical lid eliminates the influence that clump weight 1 is self-possessed to gear selecting power.It is driven on clump weight rocker arm 2 by the guide groove on gear-shifting rocker arm 7
Guide pin 3, the revolving speed of clump weight rocker arm 2 is higher than the revolving speed of gear-shifting rocker arm 7, therefore clump weight 1 is around the rotary inertia of straight pin 6
It will be amplified after being transformed into control shaft 10, and the rotation speed ratio between clump weight rocker arm 2 and gear-shifting rocker arm 7 is with gear-shifting rocker arm
The increase of 7 corners and increase, therefore the rotary inertia that clump weight 1 is transformed into control shaft 19 will be also gradually increased.The utility model can
To mitigate clump weight, enhancing shift sucking sense reduces secondary pulse, eliminates the influence that clump weight is self-possessed to block selecting power, meet vapour
The requirement of vehicle light-weight design and performance boost of shifting gears.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then shall be regarded as belonging to the protection scope that claims that the utility model is submitted determine.
