Problems solved by technology

[0003] 1. Processing difficulty and high cost
Because the outer friction ring of the double-cone lock-ring synchronizer with this structure is equipped with connecting claws, which is a special-shaped part, its structure is complex, the processing is difficult, and the processing cost is high, and it cannot be compared with the synchronization ring of the single-cone synchronizer of the same specification. achieve sharing
[0004] 2. The connection structure occupies the axial dimension

Embodiment Construction

[0013] see figure 1 , the present invention comprises a gear hub 1, an inner friction ring 4 and an outer friction ring 6, the two sides of the friction cone surface 13 of the outer friction ring 6 are flush with the two end surfaces 14, 15 of the outer friction ring 6, and the friction cone surface of the inner friction ring 4 The two sides of 12 are flush with the two end surfaces 10 and 11 of the inner friction ring 4 , and the inner friction ring 4 is engaged with the gear hub 1 . The clamping method is that the inner friction ring 4 is provided with a protrusion on the end surface corresponding to the gear hub 1, and the end surface of the gear hub 1 is provided with a groove that can be nested and matched with the protrusion corresponding to the protrusion. Wherein the protrusion and the groove appear in pairs, which can be two or more pairs.

[0014] The working process of the present invention is as follows: the sliding gear sleeve 2 is driven by the shift fork to mov...

Abstract

The invention relates to a double-cone automobile synchronizer, comprising a gear hub (1), an inner friction ring (4) and an outer friction ring (6), wherein two sides of a friction conical surface (13) of the outer friction ring (6) are level with two end faces (14 and 15) of the outer friction ring (6); two sides of a friction conical surface (12) of the inner friction ring (4) are level with two end faces (10 and 11) of the inner friction ring (4); the inner friction ring (4) is in clamping connection with the gear hub (1). The invention provides the double-cone automobile synchronizer which is low in machining difficulty and cost, resistant to wear, long in life-span and stable to work.

Description

technical field [0001] The invention relates to a double-cone automobile synchronizer. Background technique [0002] The double-cone lock-ring synchronizer has been widely used in the automobile industry. The inner friction ring and the outer friction ring of various double-cone synchronizers on the market are all directly connected. The outer circumference of the outer friction ring is provided with convex The claws (also called claws, generally three claws or six claws) are nested and matched with the recesses provided on the corresponding protrusions on the outer circumference of the inner friction ring. The inner friction ring is driven to rotate by three claws or six claws. The double cone lock ring synchronizer with this structure has the following disadvantages: [0003] 1. Processing difficulty and high cost. Because the outer friction ring of the double-cone lock-ring synchronizer with this structure is equipped with connecting claws, which is a special-shaped pa...
