Description
Technical field
The present invention relates to parking hand control valve (HCV), particularly relate to the cancel system of parking hand control valve (HCV) locking.
Background technology
Hand control valve (HCV), as a kind switching function valve, generally has three kinds of functions: braking during standstill, releasing braking during standstill, emergency brake (optional).Wherein in order to prevent maloperation, needing to design a kind of switch lock locking mechanism, opening lockable mechanism, can switch under three kinds of states; Prevent from touching hand control valve (HCV) under unforeseen circumstances by mistake, and cause hand control valve (HCV) action, parking suddenly or suddenly remove parking and produce security risk on ramp in making to travel.As shown in Figure 1, 2, the lockable mechanism of application is at present pull-type, by bar handle (wherein handle is often connected with joystick and cam) according to steering push-and-pull, can directly switch between driving and parking." driving " position in Fig. 1 is in during its middle rolling car, pull joystick to parking position according to A direction during parking, now latch 76 is along the camber line of fixed mounting 74, when sliding into parking position, latch 76 under spring force, snap in the draw-in groove that fixed mounting 74 arranges at parking position, form parking lock.First upwards lift carrying handle 73 according to the direction of B when removing parking, make the latch 76 be connected with carrying handle 73 depart from the draw-in groove of fixed mounting 74; Cam 75 drives joystick 72 and bar handle 71 to reset to road location under the effect of side direction return spring.The adjustment of brake-pressure is then by aforesaid operations, and the valve body being controlled lower end by cam 75 carries out air pressure adjustment and opening and closing.
There is following shortcoming in existing pull-type safety locking mechanism: operates uncomfortable, not smooth; Profile has limitation, with the interior trim style harmony extreme difference of vehicle newly developed; In order to the satisfied balance handling sense and outward appearance, the appearance and modeling of carrying handle and bar handle is subject to certain restrictions.
Prior art: 71-bar handle, 72-joystick, 73-carrying handle, 74-fixed mounting, 75-cam, 76-latch, 77-draw-in groove.
Summary of the invention
In order to solve the problems such as parking stick control is inconvenient, appearance and modeling is restricted, the present invention devises the cancel system of a kind of push type locking, thoroughly changes maneuverability pattern, reaches optimized handling traveling comfort, increases the object of product appearance designability.
For achieving the above object, the technical solution used in the present invention is as follows:
The cancel system of a kind of parking hand control valve (HCV) locking, it comprises:
Bar handle, has first blind hole inside from edge and the second blind hole in it, described first blind hole and described second blind hole intersect;
Button, it is placed in described first blind hole and is connected with described bar handle moving sets;
Elastic element, it is fixedly connected with described bar handle with described button respectively along described button moving direction;
Pull bar, it is placed in described second blind hole and is connected with described bar handle moving sets;
Joystick, it is connected with described pull bar, and it has latch;
Described button has the described pull bar of support and the fitting surface coordinated with described pull bar, and when described button compresses described elastic element, described pull bar moves along described second blind hole and carries on described latch.
Selectable, described first blind hole is orthogonal with described second blind hole, and described fitting surface is dip plane, and described pull bar has the antifriction-bearing box coordinated with described fitting surface, and described antifriction-bearing box can along described fitting surface scroll-up/down.
Selectable, described first blind hole is orthogonal with described second blind hole, and described fitting surface is dip plane, and described pull bar has the second fitting surface coordinated with described fitting surface, and described second fitting surface and described fitting surface fit.
Selectable, the two ends of described fitting surface have positioning plate.
Selectable, described elastic element is spring.
Selectable, described button outer end has button cap.
Beneficial effect of the present invention:
Pressed gently can be removed parking lock by palm when held bar handle thumb, external form, radian, button force and stroke all can carry out design modifying according to client's feel demand; New construction is comparatively strong from the sense of external form science and technology simultaneously, and structure realizes uncomplicated, can be widely used in the exploitation of all kinds of gas braking vehicle hand control valve (HCV); Adopt antifriction-bearing box to coordinate with fitting surface, force of rolling friction is less than force of sliding friction, and the motion of button more easily drives pull bar to move, and action is more smooth; Adopt the second fitting surface and fitting surface, ensure enough area of contact, action is more stable.
