Abstract
Disclosed by the utility model is a kind of novel synchronizer, including splined hub and combined cover, the peripheral surface of the splined hub is equipped with external splines slot, the inner peripheral surface of the combined cover is equipped with the spline coordinated with external splines slot, there is gap between the spline and external splines slot, multiple flexible sliding blocks are equipped between the combined cover and splined hub.It is the utility model structure novel, ingenious in design, there is gap between the spline and external splines slot, in the case where not influencing combined cover and splined hub and coordinating, when combined cover when moving, the friction between combined cover and splined hub can be reduced so that combined cover is more smooth when moving.
Description
Technical field
The utility model is related to auto parts fields, in particular to a kind of novel synchronizer.
Background technology
Synchronizer is there are many structure type, widely used friction inertial type of synchronizer on automobile at present.It is by friction
Effect is realized synchronous.In structure in addition to having clutch collar, splined hub, the engagement gear ring in corresponding gear, being also additionally arranged makes engagement
Set is rapidly reached synchronous mechanism with the peripheral speed of corresponding gear ring, and the two is prevented to be engaged before reaching synchronous to prevent
The mechanism of impact.Lock ring type synchronized is one of which, compact-sized, but radial dimension is small, moment of friction is smaller between the conical surface,
It is chiefly used in transmitting the speed changer of the little car and pickup truck of torque.Existing lock ring type synchronized includes splined hub and combination
The peripheral surface of set, the splined hub is equipped with external splines slot, and the inner peripheral surface of the combined cover is equipped with the spline being adapted to external splines slot,
In existing synchronizer, when combined cover when moving, there are larger frictions between spline and external splines slot, this to combine
Set compares when moving to have some setbacks.
Utility model content
Provided by the utility model is a kind of novel synchronizer, and main purpose, which is to overcome in existing synchronizer, to be combined
Set compares the problem of having some setbacks when moving.
In order to solve the above technical problems, the utility model adopts the following technical scheme：
The peripheral surface of a kind of novel synchronizer, including splined hub and combined cover, the splined hub is equipped with external splines slot, institute
The inner peripheral surface for stating combined cover is equipped with the spline coordinated with external splines slot, has gap between the spline and external splines slot, described
Multiple flexible sliding blocks are equipped between combined cover and splined hub.
The utility model further includes two steel pricker rings, two nestable, conical ring and two conjunction gears, the two steel prickers ring are set respectively in two
In the left and right side of splined hub, described two it is nestable be respectively arranged in two steel pricker rings, in described two conical ring be respectively arranged on two it is nestable in,
Two conjunction gear is respectively arranged on the outside of conical ring in two, and described two nestable peripheral surfaces are equipped with multiple protrusions, two knot
It closes tooth and is equipped with multiple jacks, each jack is inserted into for a corresponding protrusion.
Further, the inner peripheral surface of the steel pricker ring is equipped with the first nylon dead turn, and the peripheral surface of the interior conical ring is equipped with
Second nylon dead turn.
From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the following advantages that：
1, the utility model structure novel, ingenious in design has gap, is not influencing between the spline and external splines slot
In the case of the cooperation of combined cover and splined hub, when combined cover when moving, the friction between combined cover and splined hub can be reduced, made
It is more smooth when moving to obtain combined cover.
2, the inner peripheral surface of the steel pricker ring is equipped with the first nylon dead turn, and the peripheral surface of the interior conical ring is equipped with the second nylon
Dead turn, the first nylon dead turn and the second nylon dead turn can reduce nestable rubbing between steel pricker ring and interior conical ring
It wipes, to extend the service life of synchronizer.
Description of the drawings
Fig. 1 is the schematic front view of the utility model.
Fig. 2 is the schematic top plan view of the utility model splined hub and combined cover.
Specific implementation mode
Referring to Figures 1 and 2.A kind of novel synchronizer, including splined hub 1 and combined cover 2, the periphery of the splined hub 1
Face is equipped with external splines slot 11, and the inner peripheral surface of the combined cover 2 is equipped with the spline 21 coordinated with external splines slot 11.21 He of the spline
There is gap 3 between external splines slot 11, multiple flexible sliding blocks 4 are equipped between the combined cover 2 and splined hub 1.It is described
There is gap 3 between spline 21 and external splines slot 11, in the case where not influencing combined cover 2 with the cooperation of splined hub 1, work as combined cover
2 when moving, can reduce the friction between combined cover 2 and splined hub 1 so that combined cover 2 is more smooth when moving.
Referring to Fig.1.The utility model further includes conical ring 7 and two conjunction gears 8 in two steel pricker rings 5, two nestable 6, two.Described two
5 ring of steel pricker is respectively arranged on the left and right side of splined hub 1, and described two nestable 6 are respectively arranged in two steel pricker rings 5, conical ring 7 in described two
It is respectively arranged in two nestable 6, two conjunction gear 8 is respectively arranged on the outside of conical ring 7 in two.Described two nestable 6 peripheral surface is equal
Equipped with multiple protrusions 61, two conjunction gear 8 is equipped with multiple jacks 81, and each jack 81 is inserted for a corresponding protrusion 61
Enter.The inner peripheral surface of the steel pricker ring 5 is equipped with the first nylon dead turn 51, and the peripheral surface of the interior conical ring 7 rubs equipped with the second nylon
Wipe circle 71, the first nylon dead turn 51 and the second nylon dead turn 71 can reduce nestable 6 with steel pricker ring 5 and interior conical ring 7 it
Between friction, to extend the service life of synchronizer.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should all belong to the row for invading scope of protection of the utility model
For.
