Problems solved by technology
[0003] In view of this, the present invention aims to propose an anti-difficult synchronizer for picking off gears. The synchronizer is provided with six guide teeth on the tooth sleeve to limit the circumferential deflection of the synchronous ring, which can prevent the synchronous ring from colliding with the gear sleeve after it is disengaged. The flat contact at the bottom of the inverted cone effectively solves the problem that it is difficult or even impossible to remove the gear during the operation of the car

Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0023] The invention will be described in detail below with reference to the accompanying drawings and examples.
[0024] The present invention creates a kind of anti-picking difficulty synchronizer, such as figure 2 As shown, it includes gear sleeve 1, gear hub 2, synchronous ring 3 and gear arranged coaxially. The gear sleeve 1 is socketed with the gear hub 2. 1 phase socket, the gear is provided with a cone 4, the outer edge of the gear hub 2 is provided with a through groove along the axial direction, and the inner edge of the tooth sleeve 1 is fixed with a slider 5, and the slider 5 is connected to the through groove. The positions of the grooves correspond to each other. The tooth sleeve 1 is composed of small sliders, common internal teeth 11 and guide internal teeth 12 distributed along the annular...

The invention provides a synchronizer preventing a neutral gear engagement difficulty. The synchronizer comprises a gear sleeve, a gear hub, a synchronizing ring and a gear which are arranged coaxially, wherein the gear sleeve and the gear hub are in sleeve joint, the synchronizing ring is arranged on one side of the gear hub and in sleeve joint with the gear sleeve, a cone on the edge of the gear is located below the synchronizing ring, a through groove is formed in the outer edge of the gear hub in the axial direction, and a slider is fixed on the inner edge of the gear sleeve and corresponds to the position of the through groove. The synchronizer has the following benefits: six guide teeth are arranged on the gear sleeve of the synchronizer preventing the neutral gear engagement difficulty and limit deflection of the synchronizing ring in the circumferential direction, the synchronizing ring can be prevented from being contacted with an inverted cone bottom plane of the gear sleeve after separation, and the gear sleeve performs neutral gear engagement smoothly.
Description
technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to an anti-difficulty synchronizer for picking off gears. Background technique [0002] Automobile synchronizer is a kind of mechanical equipment to achieve smooth shifting of automobiles. In manual mechanical transmissions, in order to make the gears mesh at a consistent speed and achieve smooth, impact-free shifting operations, synchronizers are often used to achieve shifting. blocking operation, such as Figure 1 As shown, although this structure has been widely used, it still has certain shortcomings: under normal circumstances, the gear sleeve moves a certain distance axially to achieve gear engagement. Then the torque is transmitted, and the synchronous ring relies on inertia to contact the splined inverted cone platform of the gear sleeve; when the gear is removed, the synchronous ring produces resistance to the gear sleeve, preventing the gear sleeve from ...
