Description
Technical field
This utility model relates to automotive transmission detection equipment, particularly, relates to a kind of rolling off the production line for automotive transmission and loads examination
The Quick Connect Kit tested.
Background technology
Along with developing rapidly of Domestic Automotive Industry, the localization process of key components and parts is accelerated, and variator is as the core of automobile
Heart parts have possessed the ability of autonomous Design and large-scale production the most.In variator manufacture process, loading test run of rolling off the production line
The noise of detection variator, gearshift performance, sealing etc. are to ensure that the critical process of variator quality, are also up to ten million units levels
The bottleneck operation of assembly line.As long as improve variator by design innovation and process modification to load test run detection efficiency, with regard to phase
When in the efficiency (assembly line is line production) that improve whole piece assembly line.
Seeing Fig. 1, the most traditional variator loading Detecting data test run flow process that rolls off the production line is as follows: variator assemble after the most calmly
The pallet being loaded with variator, on pallet, is delivered to off-line test test bay by electronic raceway, relends and help positioner by position
With the position that sensor adjusts the pallet being loaded with variator, transmission input shaft heart line is positioned at same with test bay input motor
The position of axle, the output axial line of differential mechanism 1 is positioned at the position coaxial with test bay two loading motor power transmission shaft 3 simultaneously,
Variator is injected the gear oil of specified volume again, promotes pallet by hydraulic jack, the power shaft of variator is inserted with defeated
Enter in the inner spline housing that electric machine main shaft is connected, then clamped by hydraulic jack.Two be connected with two loading motor main shafts add
Carry power transmission shaft 3 (external part 2 is external splines 21) slowly to be stretched in differential mechanism two ends internal spline 11 by oil cylinder respectively, stretch out
End 2 and loading power transmission shaft 3 are fixed together by seam 22 and bolt 23, are driven by hydraulic jack and load transmission
External part 2 is directly inserted in the internal spline 11 of differential mechanism 1 by axle 3, it is easy to oil sealing 4 and internal spline 11 are damaged, and
Connection between external part 2 and differential mechanism 1 is for being rigidly connected, and internal spline 11 only staggers completely with external splines 21 and could insert
Entering, want low speed rotation to load power transmission shaft 3 during insertion, often result in that to align the spline time long, oil cylinder pushing loads and passes
Moving axis moves existence impact, if being inserted directly into oil sealing 4 and the internal spline 11 that can destroy differential mechanism 1 when staggering the most completely, even
Whole variator is caused to scrap.
It addition, load the flexible by hydraulic jack control of power transmission shaft 3, flexible stroke by proximity switch to signal control,
When different case of transmissions or correlated parts axial dimension there are differences, loading the flexible displacement of power transmission shaft 3 can not adjust by separate unit
Whole so that splined shaft axial dimension cannot compensate, when splined shaft stretches into the most shallow, poor sealing leakage of oil at oil sealing can be caused；
When splined shaft stretches into too deep, the parts such as bad variator planet wheel spindle, oil sealing can be squeezed.
At country's 13 planning and constructing industry new systems, Accelerating The Construction manufacturing power, implement " made in China 2025 "
Situation under, energy-conservation obtained vigorously supporting of government with new-energy automobile industry, ev industry is also into great-leap-forward
Period of expansion, electric automobile slows down to roll off the production line to load to detect and there is problem above too.
Chinese patent 201420654091.6 discloses a kind of automotive transmission loading bench outfan flexible drive device, the program
Middle variator is mainly guided by its trundle with the connection of output driving head, although its trundle the inner is arranged with bullet
Spring, can be connected certain cushioning effect to variator with driving head, but its trundle its butt junction location flange fully-inserted
After the upper pin-and-hole corresponding with trundle, between butt junction location end face of flange and driving head end face, yet suffer from the biggest impact, its
Cushioning effect is limited.
