Background technology
Minicar AMT transmission assembly is on the basis of former 4V1 manual transmission, is integrated with the completely new product automatically selecting gear shifting operator, clutch actuator and transmission control unit (TCU) to be formed afterwards.Gear shift action is selected to be driven by step electric machine and gear shifting motor respectively.Owing to selecting gear shifting operator assembly to be the brand-new product developed, being the Performance And Reliability of test executing device assembly product, needing separately selecting gear shifting operator assembly to carry out engine bench test.Chassis testing room is without the test-bed being specifically designed to this product testing, and recognize through investigation, consulting, what the current device that can realize loading was generally hydraulic pressure and pneumatic control is main, but research and development and the design cost of hydraulic pressure and pneumatic means are higher, the design cycle is long, and bulkyly cannot to be arranged in high-low temperature test chamber, for the test of separating final election gear shifting operator needs, chassis testing room determines a set of simple and practical, the handled easily of designed, designed and the little load simulating device of volume, builds special test stand.
Summary of the invention
The purpose of this utility model is to provide a kind of minicar AMT transmission test load simulating device, it can simulate gear shift resistance really and accurately, and can biaxial loadings be carried out, fill up in the blank selecting the test capability in the special test of gear shifting operator assembly.
The technical solution of the utility model is achieved in that minicar AMT transmission test load simulating device, by shift block, selector shaft, guide holder, load simulation spring, spring block, spacer, set nut, the auxiliary axis of guide, shell forms, it is characterized in that: on selector shaft, cover has two spring blocks and load simulation spring, load simulation spring is between two spring blocks, the spring block of selector shaft front end is fixed by set nut, the spring block of selector shaft rear end is spacing by the shaft shoulder of selector shaft, casing is on selector shaft, selector shaft front end is exposed from case nose, spacer is between shifting shaft front springs block and shell, spacing to shifting shaft front springs block, guide holder is fixedly connected with outer casing back, and selector shaft rear end is fixedly connected with shift block through guide holder, auxiliary axis of guide one end is inserted in guide holder, and the other end is fixedly connected with shift block, leads to shift block.
Good effect of the present utility model is that it is simple and practical, handled easily and volume is little, gear shift resistance can be simulated really and accurately, improve test efficiency, and can biaxial loadings be carried out, filled up in the blank selecting the test capability in the special test of gear shifting operator assembly.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, minicar AMT transmission test load simulating device, by shift block 1, selector shaft 2, guide holder 3, load simulation spring 4, spring block 5, spacer 6, set nut 7, the auxiliary axis of guide 8, shell 9 forms, it is characterized in that: on selector shaft 2, cover has two spring blocks 5 and load simulation spring 4, load simulation spring 4 is between two spring blocks 5, the spring block 5 of selector shaft 2 front end is fixed by set nut 7, the spring block 5 of selector shaft 2 rear end is spacing by the shaft shoulder 2-1 of selector shaft 2, shell 9 is enclosed within selector shaft 2, selector shaft 2 front end is exposed from shell 9 front end, spacer 6 is between shifting shaft 2 front springs block 5 and shell 9, spacing to shifting shaft 2 front springs block 5, guide holder 3 is fixedly connected with shell 9 rear end, and selector shaft 2 rear end is fixedly connected with shift block 1 through guide holder 3, the auxiliary axis of guide 8 one end is inserted in guide holder 3, and the other end is fixedly connected with shift block 1, leads to shift block 1.
As shown in Figure 2, shift block 1 is for replacing the selector fork groove in variator, and gear shift shifting block can move in this shift block 1 elongated slot, realizes selecting gear shift course of action; Selector shaft 2, for selector shaft actual in alternative variator, selector shaft 2 is designed with shaft shoulder 2-1, for fixed stop 5, realizes the biaxial loadings function of spring; Guide holder 3 and shell 9 are connected to form the installing space of load simulation spring 4, are arranged on after on sample holder 10 with shifting actuator sample 11 and are connected; Load simulation spring 4, for simulating gear shift resistance; Spring block 5 is for positioning load simulation spring 4, two shift block 5 on selector shaft 2 are located respectively by the shaft shoulder 2-1 on selector shaft 2 and set nut 7, move left and right in process at selector shaft 2, spring block 5 can do relative motion on selector shaft 2 and set nut 7; Spacer 6, for stopping that spring block 5 moves right, also can adjust the initial position after load simulation spring 4 prestrain simultaneously; Set nut 7, is connected with selector shaft 2 by screw thread, for the position of the spring block 5 of the precompression length and fixed gear shift axle 2 front end that adjust load simulation spring 4; The auxiliary axis of guide 8, for the side-to-side movement of assisted gearshift axle 2, the effect played auxiliary guiding and support.
As shown in Fig. 3,4,5, during test, when gear shift shifting block is when moving right, selector shaft 2 moves right, and now load simulation spring 4 also has the trend run to the right, but owing to being subject to the restriction of selector shaft 2 front springs block 5, load simulation spring 4 can not mass motion and can only being compressed, and this resistance stops gear shift shifting block to move right.
When selector shaft 2 is toward left movement, load simulation spring 4 also has the trend of picture left side motion, and owing to being subject to the restriction of selector shaft 2 rear end spring block 5, spring can not mass motion and can only being compressed, and this resistance stops again gear shift shifting block to left movement.Gear shift resistance simulation process when just achieving gear shift shifting block left and right back and forth movement by above-mentioned reciprocatory movement.
