Following will be combined with the drawings in the embodiments of the present invention, technical solution in the embodiment of the present invention carried out it is clear,
It is fully described by, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
As shown in figs 1 to 6, the invention discloses a kind of door check devices, including vehicle body side hinge arm 1, shaft
3, car door side hinge arm 2, clutch discs 6 and gear disk 13 and torque plate 5, wherein vehicle body side hinge arm 1 is fixed on vehicle body, and
Shaft 3 is fixed on vehicle body side hinge arm 1, i.e. vehicle body side hinge arm 1 and shaft 3 is stationary component;Vehicle door side hinge
Arm 2 is fixed on car door, and is rotatablely connected with shaft 3;Clutch discs 6 are rotatably set in shaft 3, and gear disk 13 is fixed on
In shaft 3, and the gear disk 13 can limit the rotation of clutch discs 6, in addition, torque plate 5 is set in shaft 3 and and car door
Side hinge arm 2 rotates synchronously, and clutch discs 6 can be made to make clutch discs 6 along the axial movement of shaft 3 in 5 rotation process of torque plate
It is detached from the limit of gear disk 13.
When car door stationary state, clutch discs 6 and torque plate 5 are in and stablize stitching state, while clutch discs 6 are by gear disk 13
Limit, mechanism are in the limit state of steady stability.When enabling, when enabling moment loading to torque plate 5, make torque plate 5 to from
The thrust that disk 6 generates an axial direction is closed, when this axial thrust is greater than preset value, clutch discs 6 start relatively sliding with torque plate 5
It moves and rotation, and clutch discs 6 is made to progressively disengage the limit of gear disk 13, when clutch discs 6 and gear disk 13 exit limit completely,
The aperture of adjustable car door.At closing time, shutdown torque is applied to torque plate 5, and torque plate 5 is made to generate an axial direction to clutch discs 6
Thrust, when this axial thrust is greater than preset value, clutch discs 6 and the beginning Relative sliding of torque plate 5 and relatively rotate, and
So that clutch discs 6 is progressively disengaged gear disk 13 and be gradually backed out engagement, realizes and close the door.
It is directly connected in door check device disclosed herein with car door side hinge arm 2, i.e., by vehicle door spacing
It device function and is integrated on body hinge, does not need that individually door check device is installed, improve installation effectiveness.
It can be one grade, two grades, third gear or more multi gear in practice for the limit gear of door check device
Position, wherein when for one grade, above-mentioned structure is located at clutch discs when door opening degree is default aperture and is limited by gear disk.
Door opening degree is limited in order to better improve, prevents from bumping to side vehicle or barrier when opening the door.This
A kind of mode of multi gear position limit is provided in application, specific:
There is wedge-shaped impression on above-mentioned torque plate 5, and have the wedge shape cooperated with the wedge-shaped impression convex in clutch discs 6
It rises, is that clutch discs 6 provide one by wedge-shaped impression and the lozenges of wedge-shaped protrusion to guarantee in 5 rotation process of torque plate
Upward axial force realizes the disengaging of clutch discs 6 and gear disk 13, facilitates adjustment door opening degree.Specifically, above-mentioned torque plate
The wedge-shaped impression being arranged circumferentially on 5 there are three tools along torque plate 5, and above-mentioned wedge-shaped protrusion and the wedge-shaped impression one
One is corresponding, that is, realizes the limit of multiple gears.
In specific embodiment, above-mentioned gear disk 13 and clutch discs 6 are limited by flank engagement, pass through flank engagement reality
Existing limit of the gear disk 13 to clutch discs 6, and when clutch discs 6 are by default axial force, it can be detached from flank engagement, that is, be detached from
The limit of gear disk 13.
Preferably, the tooth form of above-mentioned gear disk 13 is conical surface tooth, is had and the conical surface tooth engagement in corresponding clutch discs 6
The flank of tooth.Conical surface tooth is arranged can be convenient for the abrasion between reduction the clutch discs 6 during rotation flank of tooth.It in practice can be according to not
With need to be arranged different limit methods, as long as can be realized gear disk to the limit of clutch discs 6 and clutch discs 6 by
The limit of gear disk 13 can be detached from when default axial force.
In addition, door check device disclosed herein further includes including clutch discs 6 being pressed on torque plate 5 and shelves
Elastic component on the disk 13 of position.Specifically, the elastic component is disk spring 7, it is set to generate shelves group drag for compressing clutch discs 6
With engagement reset force.
It is as follows for the specific course of work in conjunction with structure above:
When car door stationary state, under the action of disk spring 7, the wedge-shaped protrusion of clutch discs 6 and the wedge shape of torque plate 5 are recessed
Slot, which is in, stablizes stitching state, while the conical surface tooth of clutch discs 6 and gear disk 13 is in fully engaged state, and mechanism is in static state
Stable limit state, as shown in Figure 4.
When enabling, enabling moment loading to torque plate 5 makes the wedge groove of torque plate 5 generate an axial direction to clutch discs 6
Thrust, when this axial thrust is greater than the pressure of disk spring 7, clutch discs 6 start Relative sliding and phase with torque plate 5
To rotation, and it is gradually backed out clutch discs 6 with gear disk 13 and engages, when clutch discs 6 exit completely with gear disk 13 to be engaged,
Under enabling power and the collective effect of disk spring 7, carried out rapidly behind clutch discs 6 and 13 one space of teeth of rotational offset angle of gear disk
Engagement, mechanism enter next gear limit state.If continuing to open the door, mechanism repeats above-mentioned breakdown action.Door opening action
When stopping, car door is stopped at corresponding gear state by position-limit mechanism.State is as shown in Figure 5 when car door opening crosses gear.
At closing time, on enabling moment loading to torque plate 5, the wedge-shaped impression of torque plate 5 is made to generate an axis to clutch discs 6
To thrust, when this axial thrust is greater than the pressure of disk spring 7, clutch discs 6 and torque plate 5 start Relative sliding simultaneously
And it relatively rotates, and be gradually backed out clutch discs 6 with gear disk 13 and engage;When clutch discs 6 skid off the wedge groove and cunning of torque plate 5
When on the inclined-plane outside to wedge groove, clutch discs 6 are exited completely with gear disk 13 and are engaged, but due to the effect of inertia of shutdown, are turned
Square disk 5 continues to rotate and clutch discs is driven to rotate synchronously.At this time clutch discs 6 by the pressure of disk spring 7, torque plate 5 it is oblique
Surface pressure and rotational resistance, three kinds of power reach dynamic equilibrium, and position-limit mechanism is made to be in non-limit state, keep door closing procedure flat
It is suitable.Shutdown movement stops, and when car door stop motion, clutch discs 6 are slid onto the wedge shape of torque plate 5 under the action of disk spring 7
In groove.Dynamic balance state is as shown in Figure 6 at closing time for mechanism.
The adjacent teeth angular separation of conical surface tooth is the gear angular interval of door check device, the gear on gear disk 13
Angular interval is carried out etc. point determining according to car door maximum opening angle by numbers of gear steps.Shape of the gear torque by wedge-shaped impression, ruler
Very little and disk spring 7 parameter matching computation determines, is not specifically limited herein.
