INSTRUCTIONS: TECHNICAL FIELD The present invention relates to a stepless shifting mechanism, and more particularly to a stepless shifting mechanism suitable for a vehicle. 5 [Prior Art] For a general vehicle, if the vehicle is driven by the stepless speed change mode, a stepless transmission will be assembled in the vehicle. 1 is a cross-sectional view of a conventional stepless transmission. The 10-stage transmission 9 in the drawings includes an input shaft 91, a drive plate set 9, an output shaft 913, a drive plate set 94, and a Drive belt 95. The drive belt 95 is surrounded by the drive disc set 92 and the drive disc set 94. The drive disc set 92 includes a drive disc 921, a slide drive disc 922, a stop disc 923, and a plurality of balls 924, and a drive disc set. 94 includes a drive plate 15 941, a sliding drive plate 942, and a drive plate spring 943. Please refer to FIG. 1 and FIG. 2 as an exploded view of the main part of the conventional driving disc group. The driving disc 921 and the stopping disc 923 are coaxially fixed on the input shaft 91, and the blocking disc 923 includes three slides. Block 925, the sliding drive plate 922 is located between the driving plate 921 and the stopping plate 923 and is coaxially slidably disposed on the input shaft 91. The sliding driving plate 922 includes three sliding grooves 926, which respectively accommodate three sliders. 925, and the sliding drive disk 922 includes an accommodating space 927. The accommodating space 927 is corresponding to the blocking disk 923. The plurality of balls 924 are disposed in the accommodating space 927 and respectively respectively abut against the sliding driving disk. 922 and stop plate 923. 5200815696 In addition, the drive plate 941 is coaxially fixed to the output shaft 93, and the slide drive plate 942 is coaxially slidably disposed on the output shaft 93, and the input shaft 91 is coupled to a vehicle engine 96. Therefore, the input shaft 91 can transmit the rotational power of the vehicle engine 96 to the output shaft 93 via the transmission 5 belt 95 in a stepless shifting manner, and the rotation of the input shaft 91 causes the plurality of balls 924 to push the sliding drive plate 922 with its centrifugal force. The sliding shaft 91 is axially slid, sliding the three sliding grooves 926 of the driving plate 922 and sliding relative to the three sliding blocks 925 of the stopping plate 923, and the driving disk spring 943 pushes the sliding driving plate with its elastic force. 942 slides axially along the output shaft 93. 10 However, when the stepless transmission 9 is used for a period of time, the transmission belt 95 is worn, and at this time, the transmission belt 95 is caused to wear to change the height around the driving disk group 92 and the transmission disk group 94 (e.g., 1 is indicated by the dashed line in FIG. 1 , that is, the radius of the drive belt 95 surrounding the drive disk set 92 and the drive disk set 94 will vary, and the so-called stepless speed change is achieved by the drive belt 15 95 surrounding the drive disk set 92. This is achieved by a change in the radius of the drive plate set 94, so that the wear of the drive belt 95 relatively changes the speed ratio of the drive plate set 92 to the drive plate set 94. As described above, as a result of the wear of the transmission belt 95, the maximum speed of the stepless transmission 9 is lowered, that is, the vehicle cannot reach the highest speed state, so that the vehicle may cause problems such as poor fuel consumption and high noise. Moreover, when the vehicle engine 96 is at the highest speed position due to the wear of the drive belt 95, the rotational speed of the vehicle engine 96 at this position is greatly increased, and as a result, the probability of failure of the vehicle engine 96 is greatly increased. 200815696 SUMMARY OF THE INVENTION A stepless transmission, the stepless change, the output shaft, a drive plate set, and the stepless shifting mechanism of the present invention include a power input shaft, a drive plate set, and a drive belt.

The drive belt 6 in the figure is surrounded by the drive disc unit 3 and the drive, the disc unit 5, and the drive disc unit 3 includes a drive disc 31, a slide drive disc 32, a cymbal 5 stop 33, and a plurality of balls 34.

In addition, the drive disc 51 of the drive disc group 5 is coaxially fixed on the output shaft 40, the slide drive disc 52 of the drive disc group 5 is coaxially slidably disposed on the output shaft 4, and the input shaft 2 is coupled to a vehicle. Engine 7. Therefore, when the vehicle engine 7 starts to operate, the input shaft 2 can transmit the rotational power of the vehicle engine 7 to the output shaft 4 via the transmission belt 6 in a stepless shifting manner, and the rotation of the input shaft 2 causes the plurality of balls 34 to have their centrifugal force. The top 9 200815696 pushes the sliding drive disc 32 to slide axially along the input shaft 2, and the three sliding slots 321 of the sliding drive disc 32 are respectively slid relative to each other with the three sliders 331 of the stop disc 33, respectively. The drive disc spring 53 is axially slid along the output shaft 4 by pushing the slide drive disc 52 with its elastic force. 5 The accommodating space 320 of the sliding driving disk 32 of the driving disk group 3 includes an inner ring surface 323, and drives the sliding driving disk 32 of the disk group 3 and is provided with a stopping disk 322, and each slider 331 A wear bump 332 is protruded from the top to the stop plate 322 and between the plurality of balls 34 and the inner ring surface 323. Radially spaced by a gap t (as shown in Figure 3). In the present embodiment, the stopper disk 322 is locked and assembled on the sliding driving plate 32 by a plurality of screws 324, and the wear bumps 332 are made of plastic material, and the wear bumps 332 are triangular. 3, FIG. 4, and FIG. 5 are cross-sectional views of the stepless transmission of the first preferred embodiment of the present invention after wear. After the long-range transmission 1 is used, the transmission belt 6 will wear, so the transmission The height of the belt 6 around the driving disc group 3 and the driving disc group 5 will change. At this time, the wear bumps 332 on the slider 331 will also wear at the same time (as shown in FIG. 5), because the wear bumps are worn. After the 332 is worn, the gap t between the plurality of balls 34 and the inner annular surface 323 of the sliding drive disk 32 is reduced by the wear of the wear bumps 332 (as shown in FIG. 5), and therefore, relative The moving distance of the plurality of balls 34 in the radial direction is increased, that is, the plurality of balls 34 can be further pushed by the centrifugal force to push the sliding drive disk 32 to slide axially along the input shaft 2, so that the transmission belt 6 can be absorbed. Wear. 200815696 Therefore, by designing the wear bump 332 and the wear bump 332 to radially space a gap t between the plurality of balls 34 and the inner annular surface 323 of the slide drive disc 32, the transmission belt 6 can be overcome for a long time. The influence of the after-wearing causes the stepless transmission 1 to maintain the highest speed after the transmission belt 6 is worn, so that problems such as poor fuel consumption and high noise can be avoided, and the speed of the engine 7 can be prevented from being greatly increased, resulting in a failure probability. The problem of big increase.
