Description

The brake handle with lockable mechanism motorcycle/electric car butterfly drg

Technical field

The invention belongs to butterfly brake field, relate in particular to a kind of brake handle with lockable mechanism motorcycle/electric car butterfly drg.

Background technology

Current motorcycle/electric car disc brake mainly comprises that brake handle, parking brake hydraulic actuating cylinder, disc brake block and hydraulic brake system form, brake handle is the control mechanism that braking force produces, when brake handle rotates, thereby the compressed control of parking brake hydraulic actuating cylinder hydraulic brake system braking brake block produces braking force.Yet no matter the application force on brake handle is chaufeur parking brake power initiatively, the passive brake weight still causing due to other external force, all can bring braking force to drg.

When motorcycle/electric car chaufeur was worn raincoat and travelled in the rainy day, on market, conventional raincoat is all that the parts such as handlebar, brake handle are all hidden now, and the air draught in the time of can making to travel like this can act on brake handle, thereby causes passive brake; Because chaufeur cannot expect when can brake suddenly, thereby give to travel, bring danger, if there is this situation while turning round, tend to cause the accident, particularly, under the environment that it's raining and blowing hard, this problem is particularly outstanding.Therefore how to avoid bringing braking force just to become problem demanding prompt solution because air draught is delivered to brake handle application force by raincoat.

Summary of the invention

The object of the present invention is to provide a kind of brake handle with lockable mechanism motorcycle/electric car butterfly drg, be intended to solve because air draught is delivered to by raincoat the problem that brake handle application force brings braking force.

The present invention realizes like this, a kind of brake handle with lockable mechanism motorcycle/electric car butterfly drg, this brake handle comprises parking brake handle, locking handle, handle fixed bearing, mutual interlocking gear and pivot pin, described parking brake handle, locking handle is connected by described pivot pin with described handle fixed pedestal, described parking brake handle, locking handle can rotate along the described pivot pin being fixed on described handle fixed bearing, described locking handle is located in described parking brake handle, described mutual interlocking gear connects respectively described parking brake handle, locking handle and handle fixed bearing, described mutual interlocking gear is controlled described parking brake handle by locking handle and is rotated.

Further technical scheme of the present invention is: this brake handle also comprises pull back spring, and described pull back spring one end connects described locking handle, and the other end connects described handle fixed bearing.

Further technical scheme of the present invention is: this brake handle also comprises locking handle locating dowel pin, and described locking handle locating dowel pin is connected on described parking brake handle, and the position of the corresponding described locking handle locating dowel pin of described locking handle is provided with depressed part.

Further technical scheme of the present invention is: this brake handle also comprises parking brake handle locating dowel pin, described parking brake handle locating dowel pin one end is connected to described handle fixed bearing front end, and the corresponding described parking brake handle position of the described parking brake handle locating dowel pin other end is provided with depressed part.

Further technical scheme of the present invention is: described mutual interlocking gear is comprised of circular hole, the second through hole, fluting, steel ball mounting hole and sealing screw and steel ball, described circular hole is located on described locking handle, described the second through hole is located on described parking brake handle, described fluting is located on described handle fixed bearing, by described pivot pin fixing described parking brake handle, locking handle and handle fixed bearing, described circular hole, the second through hole, fluting align, and described steel ball is packed into and fixed by steel ball mounting hole and sealing screw.

Further technical scheme of the present invention is: described fluting is two, and described groove depth is less than described steel ball radius.

Further technical scheme of the present invention is: described diameter of the steel ball equates with groove depth sum with described the second through hole, and described diameter of the steel ball equates with described first via depth one half-sum the second via depth sum.

Further technical scheme of the present invention is: described locking handle locating dowel pin adopts and is threaded in described parking brake handle.

Further technical scheme of the present invention is: described parking brake handle locating dowel pin adopts and is threaded with described handle fixed bearing.

Further technical scheme of the present invention is: described circular hole is the first through hole or hole slot.

The invention has the beneficial effects as follows: by parking brake handle, transmit the suffered air draught of raincoat, avoid locking handle to be depressed, utilize mutual interlocking gear locking parking brake handle that air draught is produced and transferred to handlebar mountain by dynamic deformation from motion, and can not make parking brake handle rotate; When chaufeur need to initiatively brake, first press locking handle, now parking brake handle is removed lockup state, thereby produces braking force; When end of braking, this device can automatically reset to initial condition locking parking brake handle, therefore this device can effectively solve under strong wind rainy weather, when wearing raincoat and driving motorcycle/electric car, thereby the passive brake weight bringing to brake handle due to air draught causes the problem of traffic safety.This handle arrangement is simple, with low cost, easy to use.
