The mechanical disc brake device of the electro-mobile structurally comprises a brake disc, a brake assembly, a pull rod, a connecting plate, and a flange. The brake disc is connected with electro-mobile wheel drums through the flange in a threaded mode. The brake disc is fastened on electro-mobile wheels. The brake assembly is fixedly connected with the center of an electro-mobile wheel shaft through the connecting plate and is used for fixing rotation direction through the pull rod. The disc brake braking is achieved by a brake being matched with the brake disc. Compared with the prior art, the mechanical disc brake device of the electro-mobile has the advantages of being reasonable in design, simple in structure, convenient to use, low in manufacturing cost, and good in braking effect.
Description
Technical field
The utility model relates to a kind of bicycle disc brake, and a kind of electric motor car mechanical formula disc brake apparatus specifically is provided.
Background technology
The day of using along with battery-driven car, braking safe became nowadays sixty-four dollar question to promote, and the battery-driven car rear braking mostly uses to rise and stops now, and major defect is that braking distance is oversize, and is more obvious when electric vehicle loading is larger; Present also some battery-driven car also adopts the hydraulic disc brake as motor bike, and hydraulic disc brake is to waste one's talent on a petty job for battery-driven car, and the lightweight speed of battery-driven car is also unhappy, and the hydraulic disc brake cost of price is high.
Summary of the invention
The utility model is for above problem, provides a kind of insensitivity good, electric motor car mechanical formula disc brake apparatus simple in structure.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of electric motor car mechanical formula disc brake apparatus comprises by brake disc, the brake assembly, and pull bar, connecting panel and flange consist of, and brake disc is threaded with electric wheel drum by flange, and brake disc is fastened on the wheel; The brake assembly is connected and fixed by connecting panel and electric bicycle wheel shaft center, and by the fixing rotation direction of pull bar, described brake cooperates with brake disc realizes the disc brake braking.
The brake assembly comprises support; rocking arm; drag-line; spring; outer brake facing; interior brake facing; brake facing spring; sliding shaft sleeve; the pump housing; piston regulating block; piston rod; the piston cover plate; threaded mandrel and nut; wherein; an end of described drag-line connecting rocker arm; the other end of rocking arm connects piston rod; and fix by threaded mandrel and nut; described piston regulating block; piston rod; the piston cover plate assemblies piston assembly; be installed on the pump housing; spring is contained between the pump housing and the rocking arm; the screw inclined plane of piston rod rotates so that the piston regulating block outwards uses, thereby brake facing in promoting.
The beneficial effects of the utility model are: compared to existing technology, adopt the similar principle of hydraulic disc brake, heat radiation is good, has improved the safety of battery-driven car driving, and the installation of this mechanical disc brake and dismounting are all easier, also need not change the structure of vehicle frame.Therefore, the utlity model has easy to use and have the advantage of safety brake performance.

The specific embodiment
Below in conjunction with the drawings and specific embodiments a kind of electric motor car mechanical formula disc brake apparatus of the present utility model is further described.
Shown in accompanying drawing 1,2, electric motor car mechanical formula disc brake apparatus described in the utility model comprises brake disc 1, brake assembly 2, pull bar 3, connecting panel 4, flange 5; Brake disc 1 is threaded with electric wheel drum by flange 5, and brake disc 1 is fastened on the wheel, and brake assembly 2 is connected and fixed by connecting panel 4 and electric bicycle wheel shaft center, by the fixing rotation direction of pull bar 3.
As shown in Figure 3 and Figure 4, wherein brake assembly 2 comprises support 1A, rocking arm 2A, drag-line 3A, spring 4A, outer brake facing 5A, interior brake facing 6A, brake facing spring 7A, sliding shaft sleeve 8A, pump housing 9A, piston regulating block 1B, piston rod 2B, piston cover plate 3B, threaded mandrel 5B, nut 6B.Wherein, piston regulating block 1B, piston rod 2B, the piston assembly of piston cover plate 3B assembled group are contained on the pump housing 9A; rocking arm 2A is contained in piston rod 2B other end; spring 4A is contained between pump housing 9A and the rocking arm 2A; threaded mandrel 5B and nut 6B are contained in the other end; by nut 6B rocking arm 2A is fixed on the piston rod 2B, and support 1A is connected with the pump housing two slip axis holes, and shoe plate two holes are connected with support two axis holes.
Rocking arm 2A: drive the piston component rotary action.
Drag-line 3A: drive rocking arm 2A action, outer application force is provided.
Outer brake facing 5A, interior brake facing 6A: produce friction force with brake disc 1.
Brake facing spring 7A: make the brake facing return.
Sliding shaft sleeve 8A: with support 1A slip effect.
Piston component (piston regulating block 1B, piston rod 2B, piston cover plate 3B, steel ball 4B, threaded mandrel 5B, nut 6B): pushing mechanism.
Principle of work of the present utility model: when drag-line 3A applies a tensile force f; rocking arm 2A draws and forwards certain position to; piston rod 2B screw inclined plane rotates so that piston regulating block 1B outwards uses in the piston component; thus brake facing in promoting; interior brake will contact first with brake disc; support begins to slide; thus outer brake facing is also contacted with brake disc, and when tensile force f increased, inside and outside brake facing clamped brake disc; produce drag friction power and play braking action; when drag-line 3A return, corresponding rocking arm 2A is by drag-line upper spring return, and the piston regulating block is return previous status; brake facing separates with brake disc under the spring-force driven dual of brake facing spring, and battery-driven car can travel again.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
