Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0024] Such as Figure 1-4 As shown, the axial dense oil groove synchronous ring of the present invention is processed with a plurality of axial dense oil grooves 3 evenly distributed on the inner tapered surface 2 of the synchronous ring 1, and the number of axial dense oil grooves 3 needs to be determined according to the inner diameter of the specific synchronous ring. The cone diameter is determined. The diameter of the inner cone of the axial dense oil groove of the present invention is φ38-φ90 mm, and the number of dense oil grooves 3 is 88-235. For products with an inner cone diameter of φ38mm, the number of oil grooves is 77 to 114; for products with an inner cone diameter of φ57mm, the number of oil grooves is 116 to 171; for products with an inner cone diameter of φ90mm, the number of oil grooves is 183 to 270; the depth C of the oil groove is 0.30...

Abstract

The invention provides a synchronous ring of a car gearbox synchronizer. A large number of axial oil grooves are machined in the inner cone face of the synchronous ring. The tooth top width of each axial oil groove is 0.30-0.45 mm. The width of each oil groove is 0.7-1.0 mm. The oil groove section area of the axial-dense oil groove synchronous ring is larger than the section area of an existing synchronous ring thread groove, so that the oil dispersing gap is enlarged, oil dispersing effect is improved, oil discharging performance is improved, gear shifting performance is improved, abrasion cannot happen easily, and the gear shifting performance of the synchronous ring is effectively improved, and the service life of the synchronous ring is effectively prolonged.

Description

technical field [0001] The invention relates to an automobile gearbox synchronizer, in particular to a synchronizing ring on the synchronizer. Background technique [0002] The synchronizer system is applied to the automobile gearbox to make shifting light and shock-free. Gear shifting is to clutch gears with different reduction ratios to achieve different driving speeds. Engage to avoid impact when gears of different speeds mesh directly. The synchronizer relies on the friction system to achieve synchronization, and the synchronization ring prevents the meshing process when the speed is not synchronized. The synchronizer is the main component that improves the gear shifting performance of the car, synchronizes the main shafts with different speeds, and transmits the output torque of the engine. Driving safety and riding comfort, and improving the acceleration and economy of the car when starting play an extremely important role, and the synchronization ring is an importan...
