Description

M273472 Amendment_Case No. 94200591 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is related to differentials, especially a type of "differential direct And differential drive control structure improvement. [Prior art]

According to the former, the new patent case No. 0 9 2 2 1 2 7 3 1 "Difference in Structure Improvement of ATV", its adjustment mechanism includes components such as adjustment shaft, idler gear, fixed seat, pusher and knob. The adjusting shaft is suspended inside the hub between the relative driven gears of the left and right rear axles, and the peripheral surface is provided with concave and convex tooth surfaces, and the distal end pivot differential gear σ meshes with the driven gears of the left and right rear axles; the idler The gear hole is fitted with a concave and convex tooth surface, which is connected to the proximal end of the adjustment shaft relative to the differential gear latch. The spring is placed on the adjustment shaft between the differential gear and the idler gear for the thrust of the idler gear to move outward. The fixing seat is fixed on the platform on the outer side wall of the wheel hub, and a coupling hole is provided inside for the push portion to be screwed therein, and a blocking piece is placed on the top of the coupling hole to restrict the pushing portion therein; A piece of positioning sleeve is inserted, and the threaded section on the outer side is screwed forward and backward in the fixing hole coupling hole; the knob cover is sleeved on the fixing seat and locked with the pushing portion, and the pushing portion can be operated to screw in the fixing hole coupling hole. Advance and retreat; by its structure, it can adjust the differential structure There are dual modes of direct drive; however, its adjustment mechanism is set outside the differential structure. If you want to change the ATV to direct drive or differential transmission, you must get off the vehicle and rotate the adjustment mechanism under the vehicle, which not only causes the driver It is inconvenient and dangerous, so its maneuverability is not good, so it cannot be widely used by players.

Creation Instructions (2) The creator is based on long-term experience in research and development of automobile components, plus personal. After careful observation and research, I found that the conventional method is as described above. The shortcomings exist, continue to focus on research and development of new structures, and after collecting data for reference and after the concept is mature, 'international trial production of sample use, and found to have very good practical results in multiple applications', I would like to provide it to many applications. That is, the main purpose of this creation is to provide a direct and differential drive structure improvement of the differential. As long as the controller is turned, the tines of the moving disk can be pulled out of the moving disk through the wire rope traction and the harrow. The eating part of the speed gear assembly enables the first transmission shaft and the second transmission shaft to be set to a direct drive or a differential drive state. Therefore, it is extremely convenient to control, and it has indeed improved safety effects. '[Embodiment] In order to enable the members of the Bureau of Examinations and those who are familiar with this technique to use the techniques, methods and structures of this creation to achieve the above-mentioned objectives, It is completely clear, and the detailed description with the drawings and numbers is as follows: First of all, please refer to the first to third pictures. The creative structure provided by this creative is a direct and differential drive structure improvement, generally The upper system calls for assembling a control mechanism (20) between the differential speed assembly (10) and the second transmission shaft (12), which uses the control mechanism (20) to make the differential assembly (10). ) The first transmission shaft (11) and the second transmission shaft (12) can be set to "direct drive" or "differential rotation state", because the differential assembly (10) is not the design of this creation Characteristics, so its internal structure and effects will not be repeated, in which
