Embodiment Construction
[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. Obviously, the described embodiments do not limit the present invention.
[0045]The present invention provides a lock-ring type inertial synchronizer with a new structure, which adopts an open ring spring 5 as its elastic element, and the two open ring springs 5 are respectively installed in the spring hook grooves 61 on both sides of the synchronizer hub 6 , the middle of the synchronizer sliding sleeve 1 is provided with a gear limit platform 11 . When in neutral, the open ring spring 5 is located on both sides of the gear limit platform 11 of the synchronizer sleeve 1 , and the open ring spring 5 only bears the installation pre-tightening force of the spring hook groove 61 on the synchronizer hub 6 . When the synchronizer is in gear, the synchronizer sleeve 1 moves axially to the g...

The invention belongs to synchronizer structures, provides a locking ring type inertial synchronizer, and aims to solve the technical problems that an existing synchronizer has a large number of parts, is not good for lightweight of the parts and is poor in overall reliability and a limiting structure is low in processing efficiency and prone to damage. According to the synchronizer, two open ringsprings are adopted as elastic elements, and a gear engaging limit table is arranged in the middle of the tooth crest of internal teeth of a synchronizer sliding sleeve; spring hook clamp grooves formounting the open ring springs are formed in two sides of the tooth bottom of external teeth of a synchronizer gear hub; an external friction ring, a middle cone ring and an internal friction ring are arranged sequentially in a sleeving manner from outside to inside and symmetrically arranged on two sides of the synchronizer gear hub, and every two adjacent contact surfaces are in conical surfacefit; when the synchronizer is in a neutral gear state, the synchronizer sliding sleeve is arranged outside the synchronizer gear hub in a sleeving manner, and the gear engaging limit table is locatedbetween the two open ring springs; and when the synchronizer is in a gear engaging state, the outer end surface of the gear engaging limit table of the synchronizer sliding sleeve are propped againstthe combined tooth end surface of a synchronizer combined gear ring.
Description
technical field [0001] The invention belongs to a synchronizer structure, in particular to a lock-ring type inertial synchronizer. Background technique [0002] like figure 1 and Figure 4 , The common lock-ring type inertial synchronizer with sliding sleeve and tooth limit is adopted, and the compression spring 05 is used as the elastic element. A downward axial force is applied to the ejector pin 09, and under the elastic action of the compression spring 05, the ejector pin 09 moves downward. The synchronizer gear hub 06 , the outer friction ring 02 and the synchronizer combined with the ring gear 07 are engaged. [0003] like figure 2 It is a schematic diagram of the structure of the lock-ring inertial synchronizer of another limiting method when it is in neutral. The working principle is the same as the above, except that the limiting is changed to be completed by setting the limiting boss on the ring gear. [0004] The above-mentioned synchronizers all have the fo...
