Abstract

The utility model discloses an automobile synchronizer, comprising a tooth sleeve (1), a hub gear and a synchronous cone (2). The utility model is characterized in that two end faces of the tooth sleeve (1) are provided with an axial correction stopper (3); the synchronous cone (2) is provided with a plurality of spline teeth; one end of the spline teeth is provided with a hook head structure axial correction stopper (4) which cooperates with the axial correction stopper (3); the surface of the cone-shaped friction pairs is provided with six oil collectors (5). The utility model is advantageous in that the automobile synchronizer is used for a bus; when the gearbox shifts, the engaging depth of the cone and the tooth sleeve can be precisely controlled; the coaxiality and the verticality of the cone-shaped friction pairs rotating face and the rotating shaft rotating center can be automatically corrected; the synchronization time is shortened.

Description

A kind of automobile synchronizer
Technical field
The utility model relates to a kind of automobile synchronizer.
Background technique
Motor bus is the main traffic tool that people go on a journey and select for use, and the market recoverable amount is big, topped wide.Improve the whole usability of passenger vehicle gearbox, at first will improve the synchronizer usability, light smoothness, safe and reliable when making its gearshift will be lacked, fast lock in time.At present the synchronizer wear rate that uses is higher, and it is dark to exist cone and tooth cover meshs, the cone engagement not just and friction pair in conjunction with tension, and the engagement that causes and disengagement are moved not phenomenon efficiently of clamping stagnation are arranged.
Summary of the invention
The utility model provides a kind of motor bus automobile synchronizer, and during gearbox gear-shift, it can accurately control the depth of engagement of cone and tooth cover, proofreaies and correct the coaxality and the perpendicularity of taper friction pair surface of revolution and rotatingshaft rotating center simultaneously automatically; The friction pair conical surface is provided with the oil scraper trap, shortens lock in time.
The utility model has adopted following technological scheme: a kind of automobile synchronizer, it comprises tooth cover, tooth hub and synchronizing cone, described tooth cover both ends of the surface are provided with axial correction snubber, have the several keys tooth on the described synchronizing cone, be provided with the gib head axis of no-feathering to proofreading and correct snubber at key tooth one end, described gib head axis of no-feathering puts axial correction snubber to the correction snubber with tooth and matches, and described synchronizing cone conical friction secondary surface is provided with 6 oil scraper traps.
Have 48 key teeth on the described synchronizing cone; Described tooth cover, tooth hub and synchronizing cone material are alloyed steel.
The utlity model has following beneficial effect: the utility model has improved the surface of friction pair conjugation, reduced the friction pair wear rate, having stopped synchronous awl and tooth cover simultaneously meshed dark, cone engagement not just and friction pair in conjunction with tension, and the engagement that causes with throw off action not phenomenon efficiently of clamping stagnation arranged, thereby improved synchronizer synchronous effect and working life, make the lighter smoothness of shifted operation of gearbox, safe and reliable.On the friction pair conical surface, be provided with 6 circular-arc oil scraper traps, the friction pair that makes relative high speed rotating braking in conjunction with the time remove lubricant oil rapidly, thereby shorten lock in time.

Embodiment
As depicted in figs. 1 and 2, a kind of automobile synchronizer, it comprises tooth cover 1, tooth hub and synchronizing cone 2, described tooth overlaps 1 both ends of the surface and is provided with axial correction snubber 3, has the several keys tooth on the described synchronizing cone 2, preferably is provided with 48 key teeth.Be provided with the gib head axis of no-feathering to proofreading and correct snubber 4 at key tooth one end, described gib head axis of no-feathering matches with the axial snubber 3 of proofreading and correct on the tooth cover 1 to proofreading and correct snubber 4, and described synchronizing cone 2 conical friction secondary surfaces are provided with 6 circular-arc oil scraper traps 5.The material of described tooth cover 1, tooth hub and synchronizing cone 2 is an alloyed steel.

Claims (3)

1. automobile synchronizer, it is characterized in that it comprises tooth cover (1), tooth hub and synchronizing cone (2), described tooth cover (1) both ends of the surface are provided with axial correction snubber (3), described synchronizing cone has the several keys tooth on (2), be provided with the gib head axis of no-feathering to proofreading and correct snubber (4) at key tooth one end, described gib head axis of no-feathering matches to proofreading and correct the last snubber (3) of axially proofreading and correct of snubber (4) and tooth cover (1), and described synchronizing cone (2) conical friction secondary surface is provided with 6 oil scraper traps (5).
2. a kind of automobile synchronizer according to claim 1 has 48 key teeth on the described synchronizing cone (2).
3. a kind of automobile synchronizer according to claim 1, described tooth cover (1), tooth hub and synchronizing cone (2) material are alloyed steel.
