Abstract

PURPOSE:To reduce a shock noise at colliding contact to a pinion mate gear, by forming a side gear and axle shaft relatively axially movable. CONSTITUTION:Position relation between the first engagement recessed part 6 and the second engagement recessed part 7 is arranged in such a manner that under a condition adapted with the point end of an axle shaft 4 to a pinion mate shaft 11 further pressed with a side gear 2 to a pinion mate gear 10, a distance of at least backlash B is provided between an internal wall 6b in the outside of the recessed part 6 and internal wall 7b in the recessed part 7. Slide resistance force between a snap ring 8 and the axle shaft 4, generated when the axle shaft 4 is tightened by the snap ring 8, is arranged smaller than tension of a spring pressing the axle shaft 4 to the direction of a differential gear 1, at movement of the side gear 2, the axle shaft 4 is arranged not to move together.

The pinion mate gear rotates together with the differential coos to rotate a pair of side gears that mesh with the pinion mate gear while facing each other in the left and right direction. The rotation of this side gear is transmitted to the rotating wheels via the axle shaft connected to the side gear.
It is now possible to do so. By the way, if the axle shaft is an independent Nasbenzi type A, that is, one equipped with a universal joint, the differential gear 61 is mounted and supported on the vehicle body frame, and the side gear of the left drive gear and the axle marked -σ are attached to and supported by the vehicle body frame. These side gears are spline connected to the shaft. There is a stopper between the two axle shafts.

However, in the differential device 1, the distance between the side gear 2 and the pinion mate gear 10 is approximately 0.1 to 0.2 μ.
When a large driving force is applied, the backlash B is pushed outward by the engagement force of the side gear 2a marked with #.For this reason, the back of the side gear 2 and the differential case 9
A gap for backlash is provided between them. On the other hand, a spring force acting on the axle shaft 4 to press and bias the differential gear M1 is acting when the drive force is low, and when the driving force becomes small, the side gear is pushed back to its original position by the spring force. Accordingly, the side gear 2 is attached to the 111th pinion mate gear 10 and repeatedly moves back and forth in m directions ξ as the driving force changes.

Therefore, when the side gear 2 reciprocates and collides with the pinion mate gear W, the mass of the axle shaft 4 and the spring force of the scissor axle shaft 4 are added to the mass of the side gear 2, causing a large impact noise. ◎ In view of this conventional problem, this book address 1IIj has a problem that the axle shaft 7) of at least one of the first engagement recess or the JllI2 engagement recess has the above-mentioned locking in the axial direction. By increasing the thickness in the axial direction of the partial shave and allowing relative axial movement between the side gear and the axle shaft by this increased amount, the side gear can move back and forth without involving the axle shaft. This is designed to reduce the impact noise when the pinion mate gear moves and collides with the pinion mate gear.Hereinafter, the embodiments of the present invention will be described with the same reference numerals given to the same parts as the conventional structure based on the drawings. Detailed Description Figure 12 shows an embodiment of the present invention, in which the @11 engagement recess 6 formed on the inner periphery of the mounting hole S (hole spline Ja) of the side gear 2 is a engagement member similar to the conventional one. 7S: The engagement recess 1 is formed on the outer periphery of the axle shaft 4 (axial spline ja) and has a thickness substantially equal to the axial thickness of the cheek clip 8. In addition to wall thickness, at least side gear 2. The gap between the pinion mate gears 10 is formed to have a width wider than 1 minute.

From the above elliptical number, when the side gear 1 reciprocates in the same axial direction of the axle shaft 4 due to fluctuations in driving force,
$1111 Between # and ζ, the installed cheek clip a is Il of the axle shaft 4! It slides within the width of the 1294 matching recess 1. Therefore, when the driving force becomes large and the first side gear 2 is farthest from the pinion mate gear (10 force),
The hole spline Ja of the side gear 2 slides on the axial spline Ba of the axle shaft 4, and the side gear 2
moves to contact T6 with the differential shaft ~ sp. At this time, if the amplification amount of the second engagement recess s7 is equal to that of the pack sleeve, when the side gear 1 comes into contact with the differential case 9, in particular, the circlip 8 2-conjunction 4-part r outer inner @y
If it also comes into contact with b, ζ will make a roar. Incidentally, the gap for the 13-minute back push is set between the back surface of the formed tooth part of the side gear 2 and the inner surface of the differential case 9. A gap of 13 minutes may be set between the 9th stage s9& and the back push.

On the other hand, when the driving force becomes smaller, the tooth clip 8 together with the side gear 2 moves toward the counterfeit pinion mate gear 10, and only the side gear 2 collides with the pinion mate gear 1o. Therefore, although only the mass of the side gear 2 collides with the impact noise at the time of this collision, the impact noise is significantly reduced to the extent that it is almost nonexistent.

という優4た効果を奏する。
Since only the side gear moves without involving the axle shaft, when the side gear collides with the pinion mate gear that meshes with this side gear, only the amount of the side gear collides and the impact noise is significantly reduced. 1
It hardly makes any noise to the occupants. Also, J
If T is formed by the bank lash of the night gear by the width of the IJ mark, only the side gear can be moved at all times, and impact noise can be almost eliminated. Furthermore, since the axle shaft does not move completely, the amount of movement of the side gear, that is, the backlash, can be increased by appropriately widening the amplification amount of the engagement recess. This has the advantageous effect of reducing processing costs for providing L, improving mass production efficiency, and reducing product costs.
